Compare with prior art, provide a pothook structure of safety belt, utilize reverse thinking, when the condition of not using, because the effect of spring, can push up the pothook spring bolt in the inboard of pothook body always, be in a closed loop's state, when using, need with the inside extrusion of pothook spring bolt just can have the neutral, then carry out the work of screw thread tightening, guarantee user's self safety.

Description

Clamping hook structure of safety belt

Technical Field

The utility model belongs to the technical field of the safety belt technique and specifically relates to a pothook structure of safety belt.

Background

The traditional safety belt hook is locked through the structure of the buckle, when the safety belt hook is not used, the buckle is in a loose or separated state, when a user uses the safety belt hook, the buckle is not locked due to self forgetting, or the phenomenon that the buckle is loose or falls off due to the friction condition during use exists, so that certain potential safety hazards exist.

Disclosure of Invention

The utility model discloses an overcome prior art not enough, provide a pothook structure of safety belt, utilize reverse thinking, when the condition not using, because the effect of spring can push up the pothook spring bolt in the inboard of pothook body always, be in a closed loop state, when using, need with the inside extrusion of pothook spring bolt just can have the neutral, then carry out the work of screw thread tightening, guarantee user's self safety.

In order to realize the above purpose, a clamping hook structure of a safety belt is designed, which comprises a clamping hook body and is characterized in that: the hook body is of a C-shaped structure, a hook lock tongue sleeve is connected and arranged below one side of the hook body, a hook lock tongue is embedded in the hook lock tongue sleeve, a baffle is connected to the bottom of the hook lock tongue, and a spring is arranged below the baffle; the top of the hook lock tongue is positioned above the hook lock tongue sleeve; the inner side of the upper part of one side of the hook body is provided with a thread structure.

The hook lock tongue is of a cylindrical structure, a protruding structure is arranged on the outer edge of the bottom of the hook lock tongue, and threads are arranged on the outer edge of the top of the hook lock tongue.

The protruding structure is a circular ring structure or a bump structure.

The thread of the outer edge of the top of the locking tongue of the clamping hook is matched with the thread of the inner side of the upper part of one side of the clamping hook body.

Compared with the prior art, the utility model, a pothook structure of safety belt is provided, utilizes reverse thinking, when the condition not using, because the effect of spring can push up the pothook spring bolt in the inboard of pothook body always, is in a closed loop state, when using, needs just can have the neutral with the inside extrusion of pothook spring bolt, then carries out the work of screw thread tightening, guarantees user's self safety.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Referring to fig. 1, 1 is a hook body, 2 is a hook bolt, 3 is a hook bolt sleeve, 4 is a raised structure, 5 is a baffle, and 6 is a spring.

Detailed Description

The invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, the hook body 1 is in a C-shaped structure, a hook lock tongue sleeve 3 is connected and arranged below one side of the hook body 1, a hook lock tongue 2 is embedded in the hook lock tongue sleeve 3, a baffle 5 is connected and arranged at the bottom of the hook lock tongue 2, and a spring 6 is arranged below the baffle 5; the top of the hook lock tongue 2 is positioned above the hook lock tongue sleeve 3; the inner side of the upper part of one side of the hook body 1 is provided with a thread structure.

The hook lock tongue 2 is of a cylindrical structure, a protruding structure 4 is arranged on the outer edge of the bottom of the hook lock tongue 2, and threads are arranged on the outer edge of the top of the hook lock tongue 2.

The protruding structure 4 is a circular ring structure or a bump structure.

The thread on the outer edge of the top of the hook lock tongue 2 is matched with the thread on the inner side of the upper part of one side of the hook body 1.

When the condition of not using, because spring 6's effect, can push up the head of pothook spring bolt 2 in the inboard of pothook body 1 all the time, be in a closed loop state, when using, need just can have the neutral with the inside extrusion of pothook spring bolt 2, then carry out the work of screw thread tightening, guarantee pothook spring bolt 2, guarantee user's self safety. In addition, the bottom of the hook lock tongue 2 is provided with a bulge structure 4, the diameter of which is larger than the inner diameter of the hook lock tongue sleeve 3, thus preventing the outer hook lock tongue 2 from being ejected out of the hook lock tongue sleeve 3 by the spring 6. The thread of the outer edge of the top of the hook lock tongue 2 is matched with the thread of the inner side of the upper part of one side of the hook body 1, so that the locking effect can be better achieved. The phenomenon that the hasps are loosened or fall off due to friction in the using process of a user is avoided.
