The utility model provides a fast detachable belt hook with few mechanical processing procedures, simple manufacture, easy installation, strong versatility, low cost and reliable performance.

Referring to Fig. 1 to Fig. 5, in order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions to realize it. The quick dismountable belt hook provided by the utility model includes a fixed hook, a belt buckle, a movable hook, a spring, a cylindrical screw and a rivet.

The round rod at the bottom of the fixing hook passes through the circular through hole at the bottom of the buckle and is riveted with the buckle. The cylindrical screw passes through the threaded through hole and the threaded blind hole processed at the top of the buckle in turn to be fixedly connected with the buckle thread. The inner hole of the spring is set On the outer side of the rivet, the rivet passes through the circular through hole at the lower end of the ring bar of the fixed hook and the circular through hole at the bottom of the movable hook and is riveted with the fixed hook.

The fixed hook described in the technical solution is a steel part, the top of the fixed hook is an open ring rod, the lower end of the ring rod is processed with a circular through hole, the middle part of the fixed hook is processed into a cylinder, and the bottom end is a round rod.

The buckle described in the technical solution is a U-shaped part made of spring steel. A circular through hole is processed at the bottom of the buckle, a threaded through hole is processed on one side of the top of the buckle, and a threaded through hole is processed on the other side of the top of the buckle. Threaded blind hole.

The top of the movable hook described in the technical solution is a slender rod, the bottom is processed into a cylinder, the center of the cylinder is processed with a circular through hole, and a through groove is processed on the side of the cylinder at the bottom of the movable hook.

The cylindrical screw described in the technical solution is a stepped cylindrical part with a thin middle part and thick ends and threads at both ends.

The beneficial effects of the utility model are:

(1) The utility model uses a cylindrical screw to connect with the open end of the buckle thread, which solves the problem that the original buckle needs to be re-sewn when it is connected with the strap, and realizes the quick connection between the strap and the buckle.

(2) The cylindrical screw of the utility model is a stepped cylindrical part with thin middle part and thick ends and two ends with threads. In this design, since both ends of the cylindrical screw can be connected with the two ends of the top of the buckle, and the buckle is made of spring steel, the U-shaped part is elastic, so it can ensure the tight connection between the cylindrical screw and the buckle, and prevent the cylindrical screw from falling off. role.

(3) The main parts of the utility model adopt standard steel for stamping processing, the output of standard section steel is large, the machining process is few, the production is simple, and the production cost is low.
