Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments is as follows:

a small-size finger strength exerciser is shown in figure 1 and comprises a pair offinger cots 1 and a pair of fixed blocks 2 (one is arranged on the left and right in figure 1), eachfinger cot 1 is arranged in a sliding cavity in the correspondingfixed block 2 in a sliding mode, the sliding cavity of thefixed block 2 can be in a playground shape, the outer side of eachfinger cot 1 is cylindrical, and thefinger cots 1 can move left and right in the sliding cavity in thefixed block 2.

Regarding the sliding movement of thefinger cot 1 arranged in thefixed block 2, two methods are designed in the present application, one of which is that, as shown in fig. 2 and fig. 3, the upper and lower ends of thefinger cot 1 are both provided with the annularsliding chutes 11, the annularsliding chutes 11 are arranged at the outer side of thefixed block 2 and are in sliding fit with thefixed block 2, that is, the relative positions of thefinger cot 1 and thefixed block 2 are fixed by the annularsliding chutes 11. The method is convenient to install, and thefinger cot 1 is not easy to fall off from thefixed block 2.

The second step is as follows: as shown in fig. 4, baffles 21 (as viewed from fig. 1) are disposed at upper and lower ends of thefixing block 2, thebaffles 21 are provided with through holes in a field shape, thefinger stall 1 is disposed in a cavity formed by the twobaffles 21 and thefixing block 2, that is, the twobaffles 21 completely dispose thefinger stall 1 in the cavity, and at this time, thebaffles 21 should leave holes for placing fingers. Thebaffle 21 can be made into a package according to actual needs, so that the aesthetic feeling is improved.

The key point of this application lies in, has designedson connecting rod 3,female connecting rod 4, two connectingblocks 5 and has compression and tensile function'sspring 6, and here,spring 6 can select for use steelwire coil spring 6 orrubber spring 6, of course, also can customize the kind that meets the requirements according to actual conditions. Specifically, the method comprises the following steps:

the outer side of one end of thesub-connecting rod 3 is provided with an external thread, and the inner side is provided with a cylindrical inner cavity A31. The inner side of one end of the female connectingrod 4 is provided with an internal thread corresponding to the external thread of themale connecting rod 3, and the inner side is provided with a cylindrical inner cavity B41 corresponding to the cylindrical inner cavity A31. Here, the shapes of the middle portions of thesub connecting rod 3 and the female connectingrod 4 are not particularly limited, and may be cylindrical or square.

In this application, there are two connectingblocks 5 altogether, and the one end and 3 swivelling joint of sub-connecting rod and the other end of one of them connectingblock 5 and 2 fixed connection of a fixed block, the one end and 4 swivelling joints of female connecting rod and the other end and 2 fixed connection of another fixed block of another connectingblock 5. Here, when thesub connecting rod 3 and the female connectingrod 4 are rotated, the relative positional relationship between the two fixingblocks 2 can be maintained due to the connectingblock 5. Preferably, a smooth conical surface is arranged at the other end of thesub connecting rod 3 from outside to inside, an annular groove a32 is arranged at the rear end of the conical surface, the connectingblock 5 is provided with a conical surface and anannular boss 51 which are matched with thesub connecting rod 3, namely, the connectingblock 5 can be directly buckled on thesub connecting rod 3, the small-mouth conical surface of thesub connecting rod 3 firstly extends into thesub connecting rod 3, then the opening of thesub connecting rod 3 expands due to the action of the annular groove a32 until theannular boss 51 is matched with the annular groove a32, and the expanded opening is reduced to form self-locking. Similarly, the other end of the female connectingrod 4 is provided with a smooth conical surface from outside to inside, the rear end of the conical surface is provided with an annular groove B42, the connectingblock 5 is provided with the conical surface and theannular boss 51 matched with the female connectingrod 4, and the connectingblock 5 is buckled on thefemale connecting rod 4. Of course, the rotational connection here can also adopt other methods, and is not limited in particular here.

Thespring 6 is arranged in a cylindrical cavity A31 and a cylindrical cavity B41, one end of thespring 6 penetrates through thesub connecting rod 3 and the fixingblock 2 and then is connected with thefinger cot 1, and the other end of thespring 6 penetrates through the main connectingrod 4 and the fixingblock 2 and then is connected with thefinger cot 1. Here, the other ends of thesub connecting rod 3 and the female connectingrod 4 are both provided with openings of themovable springs 6 to facilitate the movement by the action of thesprings 6. Thespring 6 is shown schematically and has a certain thickness and is capable of being compressed and stretched.

When thesub-connecting rod 3 and the female connectingrod 4 rotate mutually, thespring 6 in the cylindrical cavity A31 and the cylindrical cavity B41 is pressed or stretched to deform, and the connection between thefinger cot 1 and thespring 6 is problematic, so that thefinger cot 1 and thespring 6 are likely to break to cause danger, or the adjusting limit position of thefinger cot 1 and thespring 6 cannot be controlled correctly. Therefore, a pair of stop blocks 7 is designed, a cavity is formed in one end, connected with the connectingblock 5, of the fixingblock 2, the stop blocks 7 are arranged in the cavity in a sliding mode, and one end of thespring 6 is used for fixing the stop blocks 7 respectively. When the distance between the female and male connector bars 4, 3 is elongated, thestopper 7 will abut against theconnector block 5 as shown in fig. 5. When thesub-connecting rod 3 is completely screwed into the main connectingrod 4, thestopper 7 will be tightly attached to the upper outer end of the cavity of the fixingblock 2 as shown in fig. 6. The cavity of the fixedblock 2 can be cylindrical, in this case, thestopper 7 is also cylindrical, and thespring 6 is arranged on the axis of thecylindrical stopper 7. Of course, the cavity of the fixingblock 2 may be designed as a rectangular body, and thestopper 7 may be changed accordingly.

In this application, the preparation of fixedblock 2 can adopt the mode of two halves combinations, processes out sliding cavity and the cavity of fixedblock 2. And (3) mounting and placing the components according to the positions shown in the figure 1, and finally closing the two combined fixedblocks 2. In addition, the materials required by the application can be common metals according to common exercise equipment.

This application is when using, can put intodactylotheca 1 with two arbitrary fingers (same hand or different one hand all can), stretch orcompression spring 6 through the finger, and then temper the finger, consider the position difference between the different fingers, the event can be realized through the position between adjustmentsub-connecting rod 3 and the female connectingrod 4, and, throughsub-connecting rod 3 and female connectingrod 4extension spring 6, when pullingspring 6 throughdactylotheca 1, then need bigger strength, therefore, the effect of regulating power has been played.

The invention has been described above with reference to a preferred embodiment, but the scope of protection of the invention is not limited thereto, and various modifications can be made and equivalents can be substituted for elements thereof without departing from the scope of the invention, and features mentioned in the various embodiments can be combined in any way as long as there is no structural conflict, and any reference sign in the claims should not be construed as limiting the claim concerned, from which the embodiment is to be regarded as being exemplary and non-limiting in any way. Therefore, all technical solutions that fall within the scope of the claims are within the scope of the present invention.
