[0014] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0015] In order to illustrate the technical solutions described in the present utility model, the following will be illustrated by specific embodiments.

[0016] As Figures 1-3 shown, the anti-disassembly positioning wristband provided in this embodiment includes a positioning module 1 and a wristband assembly. The wristband assembly includes a first connecting band 2 and a second connecting band 3. The end of the first connecting band 2 has a connecting buckle 4, and both sides of the end of the second connecting band 3 have teeth 31. The front and rear ends of the connecting buckle 4 are respectively an inlet and an outlet. A pair of cavities 41 are formed inside the connecting buckle 4. An elastic member 42 is integrally formed on the outer side wall of the cavity 41 facing the teeth. A convex tooth has been formed on the inner side of the end of the elastic member 42. The thickness of the elastic member 42 is greater than the thickness of the second connecting band 3. An L-shaped chute 44 is opened on the surface of the connecting buckle 4 opposite to the position of the cavity, and the two L-shaped chutes 44 are symmetrical. The L-shaped chute includes a horizontal portion and a vertical portion.

[0017] c This positioning wristband needs to be removed using an unlocking member 5. In the figure, the unlocking member 5 is in a shape of a capital letter "J", and a hand-held portion 51 is integrally formed upward at the middle position of the "J" shape.

[0018] The principle of the product is that when in use, the head end of the second connecting band is directly inserted into the inlet of the connecting buckle and extends out of the outlet, during the insertion process, the clamping teeth on both sides of the second connecting band contact the protruding teeth of the elastic member, the protruding teeth are pushed outward after contacting a clamping tooth, and the elastic member resets when the protruding teeth are located between two clamping teeth. Because one surface of the clamping teeth is a plane and the other surface is a 45° inclined surface, the direction of the protruding teeth is opposite, during the insertion process, the inclined surface of the clamping teeth and the inclined surface of the protruding teeth contact, which does not affect the normal insertion of the second connecting band. When the second connecting band is pulled out in the reverse direction, the plane of the clamping teeth and the plane of the protruding teeth contact to form a limit, so that the connecting buckle of the second connecting band and the first connecting band is locked, and the anti-disassembly effect is achieved.

[0019] In the structure, the side wall of the elastic member 42 is an inclined surface and is smoothly connected with the outer side wall of the cavity, a space is left between the end of the elastic member 42 and the outer side wall of the cavity, and the thickness of the protruding teeth at the end of the elastic member is the same as the thickness of the second connecting band. When the wristband needs to be removed, the unlocking member is inserted into the longitudinal part of the two L-shaped sliding grooves, and then the unlocking member is pushed along the transverse part of the L-shaped sliding groove, during the pushing process, the two end surfaces of the bottom of the unlocking member contact the inclined surface of the side wall of the elastic member, so that the unlocking member pushes the two elastic members apart, the protruding teeth are away from the clamping teeth, and then the limit is contacted, so that the second connecting band can be normally pulled out.

[0020] Further, as a specific structure, a straight groove 32 is formed at the end of the second connecting band 3, and a convex strip 45 is arranged at the position corresponding to the straight groove 32 of the connecting buckle 4. The convex strip 45 can guide the straight groove on the one hand, and can limit the maximum insertion depth of the second connecting band on the other hand.

[0021] In addition, a shallow groove is further arranged on the side wall of the connecting buckle, a short groove is arranged in the shallow groove, and a movable push block 47 is further arranged in the shallow groove. The connecting part of the inner wall of the push block 47 penetrates out of the short groove, and the connecting part has a stop block 46. By pushing the push block, the movement of the stop block can be realized. After the second connecting band is inserted, the push block is further pushed backward, so that the stop block 46 is located in the space behind the end of the elastic member, the elastic member can be locked, and the second connecting band is prevented from being further inserted and pulled out.

[0022] The above only describes preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
