Abstract

The invention discloses a draw hook with a self-locking function. The draw hook comprises a hook body, a lock catch, a lock block and an elastic sheet. The hook body comprises a hook part and a clamp block; the hook part comprises a first end and a second end; the clamp block is fixed to the first end of the hook part; and the clamp block comprises a first surface and a second surface. The lock catch comprises a first end and a second end; the first end of the lock catch is rotatably fixed to the first end of the hook part; a protrusion block is arranged on the lock catch; one end of the lock block is rotatably fixed to the lock catch; and a clamp hook is arranged at the other end of the lock catch. The draw hook abuts against the first surface through the clamp hook, acting force for getting close to the second end of the hook part is applied to the second end of the lock catch through the elastic sheet, and therefore self-locking of the draw hook is achieved. The reliability of mounting is improved, and the technical problems that a draw device in the prior art can not achieve self-locking, and a draw rope can not be mounted firmly are solved.

Description

technical field [0001] The invention relates to the technical field of traction equipment, in particular to a traction hook with self-locking. Background technique [0002] At present, there are mainly two types of traction devices used in the chassis of special off-road vehicles, one is the type with pin shafts in the middle of the upper and lower lugs, and the other is the type with tow hooks and shrapnel. The first kind of traction device is simple in structure, without self-locking device, and it is cumbersome to put the traction rope on the pin shaft again; Contents of the invention [0003] The present application provides a towing hook with self-locking, which solves the technical problem that the towing device in the prior art cannot realize self-locking, resulting in unreliable installation of the towing rope. [0004] The application provides a towing hook with self-locking, the towing hook includes a hook body, a lock, a lock block, and a shrapnel; [0005] Th...
