Description

Novel tire-removing-free tire repairing tool

Technical Field

The utility model relates to a novel exempt from to take off child tire repair instrument belongs to tire repair technical field.

Background

In the prior art, a method for repairing a tire requires disassembling a wheel, removing the tire from a wheel hub, roughening an area near a leak point inside the tire at an inner side of the tire, attaching an unvulcanized rubber sheet, heating the rubber sheet and the tire together on a vulcanizing machine to a vulcanizing temperature, and performing partial vulcanization. After vulcanization is finished, the rubber sheet and the tire have strong adhesive force, in actual operation, due to poor temperature control precision of the simple vulcanizing machine, the situation that the tire body is damaged due to overhigh temperature can occur, and meanwhile, due to the fact that the method is time-consuming, the using range is less and less.

The most common tire repair method at present is a cold rubber patch method, which is to disassemble the tire, polish the area near the inner leakage point of the tire, then apply glue and attach the rubber patch to complete the tire repair. However, the method has the defects that holes on the tire body are not repaired, rainwater can invade from the holes, so that the framework material (steel wire) of the tire is corroded, the adhesion between rubber and the steel wire is damaged, and potential safety hazards exist. And the tire repairing method is very dependent on the adhesive strength of the rubber sheet. Once the adhesive layer leaks, the tire is decompressed in a short time, and thus there is also a safety concern.

The commonly used tire repair in the prior art also utilizes a mushroom nail to repair the tire, the mushroom nail has one more rubber rod than the rubber sheet, and the rubber rod penetrates out of the cavity from the inside of the tire during tire repair, so that the cavity is blocked. The tire repair method solves the problem of cavity corrosion, can control the leakage speed once leakage occurs, and also provides a layer of safety barrier, but still avoids failure in a certain proportion. Meanwhile, a part on the tire, namely a tire shoulder, is a part which is difficult to repair. The part has large deformation, and the common rubber sheet can be degummed in the repeated deformation and folding processes, so that the serious potential safety hazard exists. When the positions are repaired by the mushroom nails, the rubber sheets still can be degummed, only the rubber rods blocked in the holes play a role in sealing, and the tires have slow air leakage due to poor sealing performance of the rubber rods.

The introduction methods are all that the wheel needs to be disassembled, and in real life, a tire repairing method without disassembling the wheel is also provided, and the tire is repaired by using rubber strips. The tape is a fiber impregnated with glue and bonded together to form the tape. The surface of the adhesive tape is adhesive which has good viscosity and is not solidified. When the rubber strip sealing device is used, the rubber strip is folded by a tool, the rubber strip is forcibly plugged into the hole by the tool, and the rubber strip is extruded to play a sealing role depending on the elasticity of the tire body after the tool is pulled out. The tyre body has certain elasticity, the holes shrink, the space after the tool is pulled out is occupied, certain extrusion force still exists, and the tyre is sealed in this way. However, the tire repair method has uncertainty and a certain proportion of repair failures. The biggest problem is that the rubber strip is of a fiber structure, and is repeatedly extruded by a tire body in the using process, so that permanent deformation is generated, and the sealing property is lost; in addition, in the repairing process, the holes are enlarged, which increases the subsequent repairing difficulty.

In the prior art, a tire repairing nail is provided with an air stop ring structure at the head of the nail, and a conical sealing sleeve with a small front part and a large rear part is sleeved outside the nail. However, during the process of the repair screwing, the gland collapses. The thread and the air stop ring actually play a sealing role, air leakage can occur in the movement process of an automobile tire after repair, and the nail is rigid, so that the tire repeatedly deforms in the operation process of the tire, and the binding surface moves relatively and rubs, so that sealing failure is caused.

In view of the above, it is obviously necessary to develop a new tire puncture repair tool without removing the tire.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

the first embodiment is as follows: referring to fig. 1, a novel tire puncture-free tire repair tool comprises ascrew 1, and referring to fig. 4, a stickyadhesive film layer 2 is arranged on the surface of ascrew rod 5 of thescrew 1, theadhesive film layer 2 extends from the head of the screw to the screw rod area of thescrew 2, and the inner surface of theadhesive film layer 2 is adhered to the surface of thescrew rod 5 of thescrew 1.

In this embodiment, thescrew head 4 is a truncated cone-shaped structure, and the diameter of the outer surface is larger than that of the inner surface.

In this embodiment, the thickness of thescrew head 4 is 1.1mm, 1.3mm or 1.5mm, and thescrew head 4 is thinned, so that the length of the thread is further increased, and the repair space is increased.

In this embodiment, the maximum diameter of the outer surface of the head of the screw 1 (i.e. the maximum diameter of the outer surface of the truncated-cone-shaped structure) is 5.5mm, and the maximum diameter of the corresponding preferred thread is 5mm, or the maximum diameter of the outer surface of the head of thescrew 1 is 6mm, and the maximum diameter of the corresponding preferred thread is 5mm, so that the diameter of the head of the screw is reduced, which is beneficial for screwing the head of the screw into the tire hole, and further enlargement of the wound is avoided.

In this embodiment, the afterbody ofscrew 1 has the cylinder structure of smooth cambered surface type head, and the diameter size of cylinder structure is 2mm, and the height is 2mm, or the diameter size of cylinder structure is 3mm, and the height is 5mm, and the cylinder structure that has blunt round head (smooth cambered surface type head) has formed the seeker of screw, the utility model discloses a cylinder structure of blunt round head forms the direction head, and ordinary self-tapping screw, either the tip, or the drill bit of taking cutting function, then smooth blunt head in this embodiment, has unique effect in the application. The hole drilled by the nail may be inclined, both heads have a cutting function and may not follow the hole wall but rather drill a new channel, which may lead to a repair failure. And the utility model discloses a head is blunt (glossy arc spherical surface structure), and cambered surface type head structure can be for the shape similar with a certain head of egg, does not possess the drilling ability, can only go forward along the pore wall direction, and the head is glossy, also is favorable to the direction, and smooth cambered surface type head and cylinder structure are integrated into one piece in this embodiment.

In this embodiment, the diameter of thethread 6 of thescrew 1 is gradually reduced from the head to the tail.

In this embodiment, the adhesive film layer is an adhesive, such as rubber glue of type 3M4799 or other similar adhesives, and can be bonded well with metal and rubber.

In this embodiment, the head of thescrew 1 is provided with a cross-shaped groove.

In this embodiment, referring to fig. 1, theadhesive film layer 2 is uniformly covered and adhered on the screw.

After the nail is screwed into the tire body, the thread part of the nail is wedged into the rubber of the tire body to form a spiral groove. The gas leaks to have two channels, firstly along the faying face of screw thread and rubber, spiral rising leaks to the matrix outside. The second path is to cross the top of the screw thread and leak to the outside after several screw threads are crossed continuously. Referring to fig. 3, for the utility model discloses a tire's structure diagram is twisted to the instrument, the rete and the nail closely adhere, before twisting, can add the activator in the hole, the activator can soften the gluey on nail surface, and is lubricated, twists very easily. The most important purpose is to avoid the strong friction and adhesion between the film layer on the surface of the nail and the carcass, thereby damaging the wrapping of the nail by thefilm layer 2.

In the wedging process of the nail, theadhesive film layer 2 at the top of the screw teeth is inevitably stripped, so that the nail rolls and migrates inside the hole, and the inside vacancy is randomly filled. The root part between the threads is less extruded by the adhesive film, so that the adhesive film can be kept intact. The thread valley part is well bonded with the tire body, and the channel with spiral leakage is perfectly sealed. The nail glue falls off more at the top of the screw teeth. However, the combination of the thread and the tyre body is tight, and meanwhile, most of the migration of thefilm layer 2 still remains in the groove of the tyre body and the top of the thread to play a role in sealing. The length of a complete thread is approximately 10 cm, and although the sealing is intermittent, gas leakage is almost impossible.

Gas leakage, while possibly climbing over the thread crest, cannot cross the thread trough, and this channel is also perfectly sealed.

After the nail is screwed into the carcass, a sandwich structure is formed: therubber film layer 2 is clamped between the tire body and the nail. Preferably, the adhesive force between thefilm layer 2 and the carcass is strongest, the adhesive force between thefilm layer 3 and the nail is inferior, and the cohesive force of thefilm layer 2 is the lowest. When the structure is damaged, for example, by driving a nail out of a hole, the damaged surface may occur on the adhesive film itself, or if the damage occurs on the bonding surface of the adhesive film and the nail.

Theglue film layer 2 is wrapped on the nail, dried and solidified, the friction coefficient between the glue film and the rubber is large, and meanwhile, the glue film has certain viscosity. The adhesive film is easily peeled off from the nail during the screwing-in process. In order to improve the condition, a solvent is required to be added into the tire hole, the solvent plays a good lubricating role in the screwing process, and meanwhile, the solvent dissolves the surface of the adhesive film to play an activating role, so that the adhesive bonding of the adhesive film and the tire body is facilitated. To enhance the adhesion effect, an interface treatment agent may be added to the solvent. The adhesive force of the adhesive film is gradually enhanced along with the volatilization of the solvent and the absorption of the solvent by the tire body. The nail is integrated with the carcass.

In this embodiment, theadhesive layer 2 does not completely lose its adhesiveness after curing. When the glue is peeled off, the possibility of self-healing still exists.

The above reasoning was also confirmed by physical experiments. The tire repair nail manufactured in a laboratory shows good sealing capability. The tire repairing nail is already repaired after being wedged into the cavity. Can be normally used.

In this embodiment, a screw is used because thethread 6 plays a role in sealing, and in order to enhance the sealing effect, a screw is used.

In the prior art, the mushroom nail can be used reluctantly when the tire shoulder part is repaired, the mushroom nail not only has the sealing function by adhering the inner surface of the tire body with the conventional rubber sheet, but also has a certain sealing function by blocking the hole of the tire with the rubber rod, but has poor sealing property. In the using process, the deformation of the tire shoulder part is particularly large, the rubber sheet is easy to come unstuck in repeated deformation and pulling, and the rubber bar is completely used for sealing. In use, a phenomenon of slow breathing occurs.

When the tire repair nail with the air stop ring is applied to a tire shoulder part, the risk of air leakage is high. The tire repair nail is in direct contact with the tire body, and can barely play a certain sealing role under a static condition. Under the repeated deformation, a gap is gradually formed between the tire repair nail and the tire body, and the air leakage is gradually increased.

According to the scheme, the viscous rubber membrane layer is clamped between the tire repair nail and the tire body, the inner layer of the rubber membrane layer is bonded with the tire repair nail, and the outer layer of the rubber membrane layer is bonded with the tire body. When the tyre body deforms, the rubber film layer has certain deformation capacity. Even if large deformation occurs, the rubber film layer is separated from the tire repair nail or the tire body, the residual rubber material of the rubber film layer is still clamped between the tire repair nail and the tire body, a proper position can be automatically found for re-bonding under the extrusion effect, and the self-healing performance is certain.

Referring to fig. 3, the steps of the present embodiment are as follows:

1. finding thevehicle tire 7 to be repaired, rotating the puncture wound on thevehicle tire 7 to a position where the repair can be carried out, checking whether the puncture wound contains punctured foreign matters or not, and if so, pulling out the foreign matters;

2. cleaning a wound by using an activating agent or a solvent, aligning the tail part of ascrew 1 for repairing a tire to the puncture wound, matching a tool with a cross groove, rotating the tool under the action of an external force to drive the head part of the screw, a rubber membrane layer and the tail part of the screw, wherein the tail part of the screw is of a cylindrical structure with an obtuse circular head and is continuously extruded into the puncture wound along the path of the wound to form a sandwich structure, and the rubber membrane layer is clamped between a tire body and a nail; in the screwing process, the activating agent or the solvent has a lubricating effect, and simultaneously the surface of the rubber film layer is dissolved to play an activating effect, so that therubber film layer 2 is favorably bonded with the tire body of thetire 7, the rubber film layer is screwed continuously, the threads of thethread 6 are meshed with the tiresteel wire layer 8 until the outer end surface of the head of thescrew 1 is flush with the outer surface of thetire 7 or the outer end surface of the head of thescrew 1 is sunk into the outer surface of thetire 7;

3. over time, the adhesive strength of thefilm layer 2 will gradually increase over time, so that the nail is integrated with the carcass.

Example two: referring to fig. 2, the novel tire puncture-free tire repair tool comprises ascrew 1, wherein a stickyadhesive film layer 2 is arranged on the surface of ascrew rod 5 of thescrew 1, theadhesive film layer 2 extends from the head of the screw to the screw rod area of thescrew 2, and the inner surface of theadhesive film layer 2 is adhered to the surface of thescrew rod 5 of thescrew 1.

In this embodiment, referring to fig. 2, thefilm layer 2 is wrapped and adhered to the screw, and has a substantially conical structure.

In the embodiment, the thickness of the screw head is 1.2mm, namely the thickness of the truncated cone-shaped structure is 1.2mm, the screw head is thinned, the length of the thread is further increased, and the repairing space is improved. In this embodiment, the diameter of the outer surface of the head of thescrew 1 is 5.5mm, and the diameter of the head of thescrew 1 is reduced, so that the whole screw and the head of the belt are conveniently screwed into the tire body, and the wound is not obviously enlarged.
