[0024] Embodiment

[0025] Please refer to Figures 1 to 3 , Figure 1 which is a schematic structural diagram of the present utility model, Figure 2 and which is an exploded structural diagram of the present utility model, Figure 3This is a cross-sectional view of the utility model. This embodiment provides an anti-theft lock catch, which includes a cap-shaped catch body 1, a lock body 2, and a catch base 3. The lock body 2 is arranged inside the cap-shaped catch body 1 and sleeved on the catch base 3. The cap-shaped catch body 1 is locked with the catch base 3 through the lock body 2. The cap-shaped catch body 1 has a hollow structure 11, and an annular groove 12 for carrying the lock body 2 is formed on the inner wall of the hollow structure 11. The lock body 2 is arranged inside the hollow structure 11. The lock body 2 includes a hollow fixed clamping base 21 and an elastic clamping opening 22. The elastic clamping opening 22 is fixed on the hollow fixed clamping base 21. The elastic clamping opening 22 can also be integrally injection-molded with the hollow fixed clamping base 21. The elastic clamping opening 22 is in the shape of a frustum of a cone. The catch base 3 includes a base plate 31, a connecting rod 32, and a cap-shaped locking tongue 33. One end of the connecting rod 32 is fixed on the base plate 31, and the end of the connecting rod 32 away from the base plate 31 is integrally formed with the cap-shaped locking tongue 33. The cap-shaped locking tongue 33 is inserted into the hollow fixed clamping base 21 and locked by the elastic clamping opening 22. When in use, in this application, the catch base 3 is inserted into the lock body 2 arranged inside the cap-shaped catch body 1, and then the lock body 2 is used to tightly lock the catch base 3. Specifically, the cap-shaped locking tongue 33 extends into the elastic clamping opening 22 arranged inside the hollow structure 11 from the hollow fixed clamping base 21 and is tightly locked by the elastic clamping opening 22. The anti-theft lock catch designed in this application can quickly realize the locking and unlocking between two or more objects. Compared with the lock catch with a traditional component structure, the structure of this application is simpler, more convenient and reliable to use, and has a low manufacturing cost. In order to ensure applicability to more objects and take into account the structural stability of the anti-theft lock catch, the diameter of the cap-shaped catch body 1 is preferably greater than or equal to 50 mm, the diameter of the hollow structure 11 is preferably greater than or equal to 30 mm and less than or equal to 45 mm, and the length of the connecting rod 32 is preferably 15 - 55 mm. In order to extend the service life of the anti-theft lock catch, a protective coating is applied on the surface of the anti-theft lock catch. The protective coating is composed of an epoxy resin layer, a soft waterproof buffer layer, and a wear-resistant surface layer stacked in sequence. The soft waterproof buffer layer is made of thermoplastic polyurethane material, and the wear-resistant surface layer is made of polyurea material. The protective layer designed in this way can not only prevent the anti-theft lock catch from oxidizing and rusting but also give the anti-theft lock catch a buffering force, providing a more comfortable touch for the user during use.
