DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 The utility model provides a technical solution: a self-locking clamp, comprising a first clamp body 1 and a second clamp body 2, first fixing blocks 3 are installed at both ends of the first clamp body 1, and second fixing blocks 4 are installed at both ends of the second clamp body 2; the first clamp body 1 and the second clamp body 2 are used to contact with the clamped object and clamp the clamped object. After the first fixing block 3 and the second fixing block 4 are connected, they can fix the first clamp body 1 and the second clamp body 2.

[0027] A plug rod 5 is installed on one side of the first fixing block 3 close to the second fixing block 4, and one end of the plug rod 5 slides through the second fixing block 4 and extends to the outside of the second fixing block 4; the plug rod 5 is provided to connect the first fixing block 3 and the second fixing block 4.

[0028] Furthermore, a connecting block 6 is installed on the side of the first fixed block 3 away from the second fixed block 4, and self-locking components are installed on the upper and lower ends of the connecting block 6 close to the second fixed block 4; the connecting block 6 is provided to connect and fix the two sets of self-locking components.

[0029] The first teeth 7 are installed at both the upper and lower ends of the second fixing block 4, and the top of the first teeth 7 extends to the inside of the self-locking component and is engaged with the self-locking component. The self-locking component includes a housing 8, and a support block 9 is arranged inside the housing 8. Pillars 10 are slidably inserted at the four corners of the support block 9, and both ends of the pillars 10 are connected to the inner wall of the housing 8. By providing the pillars 10, the pillars 10 are used to support the support block 9, and the support block 9 can stably move up and down inside the housing 8.

[0030] Furthermore, the second tooth 11 is installed on the side of the housing 8 close to the first tooth 7, and the bottom of the first tooth 7 is engaged with the second tooth 11. A through slot 12 adapted to the second tooth 11 is provided on the side of the housing 8 close to the first tooth 7, and the bottom of the first tooth 7 slides through the through slot 12 and extends to the inside of the through slot 12. The through slot 12 is provided to facilitate the first tooth 7 to enter the inside of the housing 8 and connect with the second tooth 11.

[0031] It is worth noting that the first teeth 7 and the second teeth 11 are both arranged in right triangles, the side of the second teeth 11 close to the first fixing block 3 is arranged in a right angle, and the side of the first teeth 7 close to the first fixing block 3 is arranged in an inclined surface.

[0032] Specifically, springs 15 are installed at four corners of the support block 9 away from the second tooth 11 , and one end of the spring 15 away from the support block 9 is connected to the inner wall of the housing 8 .

[0033] When the first hoop body 1 and the second hoop body 2 are self-tightened, the second hoop body 2 is moved close to the first hoop body 1, and the first hoop body 1 and the second hoop body 2 are close to each other, so that the hooped object can be tightened, and the first fixing block 3 and the second fixing block 4 are also close to each other, and the second fixing block 4 is connected to the first fixing block 3 through the insertion rod 5, and the second teeth 11 at the top and bottom of the second fixing block 4 enter the interior of the shell 8 through the through groove 12. In the process of driving the second teeth 11 to move, the second fixing block 4 will push the first teeth 7 to push the second teeth 11 downward, and the second teeth 11 slide on the surface of the pillar 10, and at the same time, the second teeth 11 drive the support block 9 to move downward and press the spring 15. When the first hoop body 1 and the second hoop body 2 tighten the hooped object, the second teeth 11 will mesh with the first teeth 7. The first teeth 7 and the second teeth 11 can be tightly connected through the reverse thrust of the spring 15, and the second teeth 11 cannot move to the side away from the first fixed block 3. At the same time, by setting the insertion rod 5, the moving trajectory of the second fixed block 4 can be limited, so that the second fixed block 4 and the second hoop body 2 can be limited to achieve the purpose of self-locking.

[0034] In addition, a screw 13 is installed on the side of the support block 9 away from the first fixed block 3, and a screw sleeve 14 is threadedly connected to the surface of the screw 13. A movable groove 16 adapted to the screw 13 is opened on one side of the housing 8, and one end of the screw 13 slides and extends to the outside of the housing 8 through the movable groove 16. When the hoop needs to be disassembled, the screw 13 is pressed toward the side away from the second teeth 11, and the screw 13 drives the support block 9 and the second teeth 11 to separate from the first teeth 7, so that the second fixed block 4 loses support and limitation, and the second fixed block 4 and the second hoop body 2 can be separated from the first fixed block 3 and the first hoop body 1, and the screw sleeve 14 is rotated at the same time. When the screw sleeve 14 is tightly fitted with the housing 8, the friction between the screw sleeve 14 and the housing 8 increases, and the position of the screw 13 and the support block 9 can be limited by the friction generated by the screw sleeve 14, so that it is convenient to adjust and limit the position of the second teeth 11 during disassembly, so as to achieve the purpose of easy disassembly and assembly.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
