Automatic telescopic beltTechnical field
The present invention relates to a kind of belts, especially automatic telescopic belt
Background technique
Existing belt is using belt and two components of belt fastener, by the way that leather belt head is fixed on the one of belt fastener with the age of a draught animalEnd, the other end pass through belt fastener.Snak link on belt fastener again clasps belt.
Existing belt disadvantage still has belt exposing when being to buckle, and can not achieve automatic accomodation, and belt is totally blocked upGreat burden is brought to human body waist.And belt is also cut for the people of different building shape.It is travelling outdoors or is going on businessWhen it is inconvenient to carry.And the leather amount used when the production of existing belt is excessive, and cost of manufacture is high.
Summary of the invention
What the present invention was created is by making belt realize automatic telescopic from power resilient strip and gear drive is stored.Facilitate receiptsIt receives, mitigates waist burden.
The technical issues of to solve existing belt, innovation scheme of the invention are as follows:
A kind of automatic telescopic belt, including storing power dynamical system certainly (by resilient strip, one end of active powershift gear, bevel gearConstituted), power protective shell, transmission shaft, crawler belt, belt, two active buttons (one on leather belt head and shell and shellButton uses when being storage belt the other is when fixed leather belt head uses) and leather belt head fixing groove constituted.It is described to store power certainlyIt include resilient strip and active powershift gear and bevel gear in dynamical system.Dynamical system, which is individually isolated, is passed power by bevel gearOut.
It include two main shafts in crawler belt, crawler belt is stuck on the gear on main shaft both sides.When bevel gear passes powerWhen gear among to main shaft, main shaft rotation is to drive crawler belt to rotate.And it then drives and is fixed on when crawler belt rotationLeather belt head is sticked into the fixing groove on shell by the belt rotation on crawler belt when by apron drawing to position suitable with waistIn the middle.Fixed activity bar inside the shell will prevent gear from rotating clockwise when using belt, and rotating counterclockwise does not influence,And it can be rotated clockwise pressing activity bar button backgear.When not needing using belt directly by the fixation on lower casingSlot active button (all transmission parts inside belt can be realized because of resilient strip recycling elastic force and be rotated clockwise at this time) canBelt to be accommodated into shell.
The resilient strip and active powershift gear will be fixed in power protective shell.
The bevel gear will be fixed in the preformed hole among power protective shell both ends.
The transmission shaft will be fixed on monolithic case head and the tail both ends.
The crawler belt will be stuck on the gear on line shaft both sides.
The belt will be fixed on above crawler belt.
The activity bar will be fixed on inside monolithic case.
The button will be fixed on outside monolithic case.

Specific embodiment
Automatic telescopic belt as shown in Figure 1 is by monolithic case 13, crawler belt 6, transmission shaft 4, power protective shell 5 and shellThe main parts sizes such as resilient strip 1, active powershift gear 2, bevel gear 3 are constituted.
Power is stored by the resilient strip 1 (selecting high tenacity steel) being fixed on power protective shell 5, the principle for storing power is up timeNeedle discharges elastic force, stores elastic force counterclockwise.1 other end of resilient strip is fixed on active powershift gear 2, then will be moved by bevel gear 3Power passes to transmission shaft 4 above (transmission shaft 4 will be fixed on monolithic case).Crawler belt 6 is fixed on transmission shaft 4 to drive crawler belt 6Rotation, and the belt 7 being fixed on above crawler belt 6 when crawler belt 6 rotates can also rotate with it.When belt 7 is stretched to sufficient lengthWhen fixed belt waistline may be implemented with fixing groove 11 by leather belt head buckle 10.Belt need not be passed through as existing product againHead.Also belt need not be cut because waistline is wide or narrow again.Pressing fixing groove active button 12 when not in use then can be withBelt is recycled.
