Description

Technical Field

[0001] The invention relates to the field of buttons, in particular to a locking buckle. Background Art

[0002] Buttons, also known as "buttons". In ancient Rome, the earliest buttons were used as decorations, while brooches were used to fasten clothes. In the 13th century, buttons had the same function as they do today. At that time, people knew how to make buttonholes on clothes, which greatly improved the practical value of buttons. In the 16th century, buttons became popular. With the widespread use of buttons, ordinary buttons with buttonholes could no longer meet people's growing needs, and plug buckles gradually emerged. Currently, there are many types of plug buckles used and sold on the market, and they are widely used. Common products include school bags, backpacks, waist bags, baby carriers, ropes, pet products, and special-purpose clothing products. Common plug buckles are generally composed of male buckles and female buckles, and corresponding buckle mechanisms are respectively provided on the male buckle and the female buckle to achieve buckle. First, since the locking part of this type of buckle is designed at the end of the buckle pin, it can only achieve single-point or double-point locking at the same torque, and cannot withstand large pulling force and multi-angle pulling force. The lever arm is long, and a slight force will cause deformation or release of the buckle locking part, and the reliability is poor; secondly, since this type of buckle adopts a plug-in locking structure, the buckle itself is large in size, and it will take up more space for installing and placing the buckle body during use, and the application scenarios are limited; thirdly, after this type of buckle is locked, it is necessary to press the pins at the same time to release them so that they can be released at the same time, which is not quick in operation. In summary, this type of buckle cannot solve the application needs of more complex scenarios, and cannot fully meet people's life needs. Summary of the invention

[0003] In order to overcome the above problems, the present invention provides a locking buckle.

[0004] The technical solution of the present invention is: a locking buckle, comprising a first mortise, a second mortise and a tenon, wherein the inner side of the first mortise is provided with N+1 recessed mortise grooves, the outer side is provided with a first mortise fixing groove, and the inner side of the first mortise is provided with a through hole transversely; the inner side of the second mortise is provided with N+1 transversely protruding mortise heads, and the outer side is provided with a second mortise fixing groove; the mortise heads are provided with a through hole transversely; the tenon is column-shaped; it is divided into two sections, both of which are column-shaped; the width of one section is slightly smaller than that of the other section, a tenon fixing groove is provided at the edge of the section with a smaller width, and the length of the section with a smaller width is smaller than that of the section with a larger width.

[0005] A locking hole is arranged on one side of the front side of the inner side of the first mortise, which is located above the through hole; two clamping holes are arranged on the other side of the back side of the first mortise; and a slideway is arranged between the two clamping holes.

[0006] The mortise grooves correspond to the mortises; the number of the mortises is the same; the mortise on the second mortise can be inserted into the mortise groove on the first mortise, and the mortise is connected together, and the tenon is inserted into the through hole and the through hole.

[0007] The maximum inner diameter of the through hole and the through hole corresponds to the maximum outer diameter of the tenon.

[0008] The wider section of the tenon is provided with N+1 mortise grooves on one side, each mortise groove is provided with a buckle and a hook, and the hook is an inverted "L" shape; the tail end of the longer section of the tenon is provided with an anti-slip device, and the tenon groove at the tail end is also provided with a limiting buckle, which is located behind the hook; a raised clamping point is provided on the smaller section of the back side of the tenon at the connection between the smaller section and the larger section, and the clamping point corresponds to the clamping hole.

[0009] The first mortise and tenon, the second mortise and tenon are all made of nylon.

[0010] Compared with the prior art, the beneficial effects of the present invention are: better tensile strength; smaller connection size of the buckle body; convenient and quick opening with one hand. First, the locking part designed by the invention realizes lateral connection in the middle of the buckle, which can realize N+1 multi-point locking, can withstand large lateral tension and inclination tension, has a short force arm, is not easy to deform or lock release, and has good tensile resistance and reliability; secondly, due to the structure of the invention adopting a plug-in buckle, a central axis through-core locking structure, the volume of the buckle is significantly reduced, and only a small space is required for installing and placing the buckle body during use, and the application scenarios are more extensive; thirdly, after the buckle is locked, the invention only needs to lift the tenon body to release the mortise and tenon groove (or mortise body) on both sides, which is convenient and quick and can be operated with one hand. In summary, the invention solves the technical problems of easy unlocking, poor strength, large volume, and difficult operation of traditional buckles in the prior art, provides more choices for the application needs of more complex scenarios, and can meet people's needs for high-strength, quick-opening, and easy-to-use buckles.
