Description

A kind of safety hook of loop wheel machine

Technical field

The utility model relates to a kind of hook, specifically a kind of safety hook of loop wheel machine.

Background technology

In commercial production, during the heavy object, loop wheel machine is indispensable transportation means, and the hook of loop wheel machine is the vitals on the loop wheel machine.Existing loop wheel machine hook also exists certain not enough, and the unhook accident often occurs, and affects production safety.

The utility model content

Technical problem to be solved in the utility model provides a kind of safety hook of loop wheel machine, can prevent that object from breaking off relations, and guarantees production safety.

The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: a kind of safety hook of loop wheel machine, comprise coupler body, be provided with snap ring at coupler body, the bill section of the bottom of snap ring and coupler body is hinged, root at coupler body is provided with the grab that matches with snap ring, described grab is J-shaped, its crotch end is towards snap ring, and match with snap ring, the other end and the coupler body of grab are hinged, both sides in the bottom of snap ring also are provided with connecting lever, and under snap ring was enclosed within state on the grab, connecting lever was equal with the medial surface of coupler body.

The beneficial effects of the utility model are: simple in structure, be convenient to processing, and can prevent that object from breaking off relations, and guarantees production safety.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Mark among the figure: 1, coupler body, 2, snap ring, 3, grab, 4, connecting lever.

The specific embodiment

As shown in the figure, a kind of safety hook of loop wheel machine comprises coupler body 1, be provided with snap ring 2 at coupler body 1, the bill section of the bottom of snap ring 2 and coupler body 1 is hinged, is provided with the grab 3 that matches with snap ring 2 at the root of coupler body 1, and described grab 3 is J-shaped, its crotch end is towards snap ring 2, and match with snap ring 2, the other end of grab 3 and coupler body 1 are hinged, also are provided with connecting lever 4 in the both sides of the bottom of snap ring 2, under snap ring 2 was enclosed within state on the grab 3, connecting lever 4 was equal with the medial surface of coupler body 1.

This hook structure is simple, is convenient to processing, hang up object after, snap ring 2 is stuck on the grab 3, when object slides and during collision snap ring 2, connecting lever 4 is subject to object to be stopped to snap ring 2 directions, prevent from that snap ring 2 from rotating to come off.When simultaneously snap ring 2 was outwards pushed up, grab 3 was tilted upward, with snap ring 2 hang tighter, can prevent that object from breaking off relations, and guarantees production safety.
