Description

buckle

technical field

The utility model relates to a buckle.

Background technique

At present, the belt buckles (also known as lanyard buckles and certificate card buckles) of the prior art include a rope fixing buckle and a hook, but the rope fixing buckle and the hook are all fixedly connected. When taking or displaying the ID card, the fingers are held on the rope fixing buckle, which makes the connection between the hook and the rope fixing buckle prone to stress concentration, which makes the hook easy to be fixed on the rope The joint of the buckle is broken, so there is a problem of poor stability in use.

Utility model content

The utility model provides a belt buckle with better stability in use aiming at the above problems.

The technical scheme used by the utility model to solve the above problems is to provide a belt buckle with the following structure, which includes a fixed buckle and a hook, and the upper end of the hook is hinged to the lower end of the fixed buckle.

After adopting the above structure, compared with the prior art, because the hook and the fixing buckle are hinged in the utility model, in the process of use, when people take or display the certificate card with their fingers on the fixing buckle, the certificate card and the card Under the influence of the hook's own gravity, the card surface of the ID card is always in the vertical direction, which is convenient for taking or displaying the ID card, and there will be no stress concentration at the connection between the hook and the fixing buckle, so it is also There is no situation that the hook is easy to break at the joint of the fixed buckle, and the use stability is good. Therefore, the utility model has the characteristics of good stability in use.

As an improvement, the upper end of the hook is provided with an opening, the opening is provided with a hinge shaft, the lower end of the fixed buckle is provided with a bump, and the bump is provided with a hinge hole hinged with the hinge shaft, and The axis of the hinged hole is parallel to the width direction of the fixed buckle; after setting in this way, there is no need to punch holes on the fixed buckle, so that the strength of the fixed buckle is better, thereby ensuring the connection strength between the fixed buckle and the lanyard, and improving the use of the utility model Stability, at the same time, the hook of this structure can be integrally formed with the hinge shaft, thereby shortening the production cycle, improving production efficiency, and reducing production costs.

As a further improvement, the fixed buckle is divided into a front part and a rear part, the inner wall of the front part is provided with a groove, and the upper end of the groove is opened on the upper end surface of the front part; The part is detachably connected, and the groove is provided with a snapping mechanism; the front part or the rear part or the front part and the rear part are connected with the bump; the fixed buckle of this structure is convenient to form, and it is also convenient for the worker Assemble, and after the snap-in mechanism is set, the connection strength between the fixed buckle and the lanyard is better, and the lanyard and the fixed buckle can bear greater pulling force, thereby further improving the use stability of the utility model.

As a further improvement, one side of the rear part is connected to one side of the front part through a flap; after this arrangement, the front part and the rear part are of an integrated structure, which can be injection molded at one time, and can also effectively avoid In the process of transportation and storage, if the front part or the rear part is lost, it will not be possible to assemble in pairs, thereby further improving the assembly efficiency of workers and reducing production costs.

As a further improvement, the bottom surface of the groove is provided with several tapered first protrusions, and the inner wall of the rear part is provided with several tapered second protrusions that are engaged with the first protrusions. protrusions; when the front part is connected to the rear part, the first protrusion and the second protrusion intersect; the structure of the interlocking mechanism of this structure is simple, easy to form, does not require separate parts, and the production efficiency is high. The cost is also lower, and the stability of the connection is also better.

As a further improvement, the inner wall of the rear part is provided with a concave, and the upper end of the concave is opened on the upper end surface of the rear, and the second protrusions are located in the concave, and the concave and the groove Relatively set; then after being set up like this, make the front part and the back part be separated in half, not only be conducive to forming like this, also be beneficial to the position limiting of the lanyard and the connection strength of the front part and the back part, make the utility model more cost-effective. While reducing, the stability of use is further improved.

As a further improvement, the bump is divided into a front block and a rear block, the front block is connected to the lower end of the front part, the rear block is connected to the lower end of the rear part, and the inner wall of the front block and the rear block A first arc-shaped groove and a second arc-shaped groove are respectively provided on the inner wall of the inner wall. When the front part is connected with the rear part, the first arc-shaped groove and the second arc-shaped groove form a hinge hole; , making the hinge hole easier to form, reducing the difficulty of demoulding, improving the yield, so that the cost is lower, and it is also easier for workers to install the hinge shaft on the hook into the hinge hole, so that the installation efficiency of workers is higher.

As a further improvement, a first step is provided below the first arc-shaped groove on the inner wall of the front block, and a second step is provided below the second arc-shaped groove on the inner wall of the rear block; When connecting with the rear part, the first step and the second step are staggered; after the steps are set, the gap between the front block and the rear block under the arc-shaped groove is no longer linear, so that the hinge axis can be aligned to the front when the hook is pulled down. The stress action of the block and the rear block makes the gap between the front block and the rear block less likely to become larger, and the connection stability of the hinge shaft and the hinge hole is better and less likely to be disengaged.
