[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1-Figure 3 As shown, it includes a lock body 1, with guide rails 4 symmetrically arranged inside the lock body 1, and lock frames 5 slidably mounted on the two guide rails 4. The lock frame 5 moves vertically on the guide rails 4, and a plurality of lock heads 3 are welded to the lock frame 5. A fixed column 11 is provided on the inner side wall of the lock body 1, and a shift block 6 is rotatably mounted on the fixed column 11. A pull rod 7 is provided in the lock body 1, and the pull rod 7 is inserted into the lock body 1. The pull rod 7 has a guide groove 71 formed therein. A guide shaft 12 matching the guide groove 71 is provided above the inner side wall of the lock body 1, and the guide shaft 12 moves in the guide groove 71. A tension spring 9 is provided on the pull rod 7, and the right end of the tension spring 9 is fixedly connected to the lock hook 8;

[0019] A second guide shaft 13 is provided on the inner side wall of the lock body 1, and a second guide groove 72 is provided on the pull rod 7. The second guide shaft 13 passes through the second guide groove 72, and the second guide groove 72 is parallel to the first guide groove 71;

[0020] One end of the shift block 6 is connected to the lock frame 5, and the other end of the shift block 6 is connected to the pull rod 7. The shift block (7) is designed in a "V" shape.

[0021] As an optimization solution of the present invention, by adding two guide rails 4 to the lock body 1 and installing a tension spring 9 between the pull rod 7 and the lock hook 8, the side lock can be made more stable, and the assembly is more reasonable, compact, smooth, and quiet. At the same time, the side lock will not be loose or stuck. The installation of the tension spring 9 creates a space for movement between the lock hook 8 and the pull rod 7, and the provision of the tension spring 9 makes the size more convenient and reserves space during assembly.

[0022] The use process of this utility model:

[0023] When this device is needed, first pull the main lock, and the lock tongue of the main lock drives the lock hook of the side lock to move. At the same time, the lock hook drives the shift block to rotate. Then, the shift block drives the lock frame to move vertically on the guide rail. Since the lock frame is fixedly connected to the lock head, the lock head is pushed open, and the side lock work is completed.

[0024] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
