Description

Technical Field

[0001] This application relates to the field of rope buckle technology, and in particular, to a self-locking rope buckle. Background Art

[0002] Rope buckles can conveniently fasten items that need to be tightened quickly. Rope buckles have the advantages of simple operation and convenient use, so they are increasingly favored by people.

[0003] Currently, the mainstream rope buckle products on the market, such as sliding or double-sided extrusion rope buckles, due to the limitations of their structural design, often result in relatively large sizes of the rope buckles and require two hands to operate. Therefore, it is difficult to meet the diverse needs of modern consumers for rope buckles. Especially in scenarios such as underwear that require frequent adjustment and often need to be operated with one hand, the inconvenience of traditional rope buckle designs is more significant. Moreover, the large size of the rope buckle easily affects the comfort of the wearer and reduces the aesthetics of the rope buckle.

[0004] In view of the above related technologies, the inventor believes that designing a small, thin, beautiful and easy-to-operate rope buckle has become an urgent problem to be solved in the current development process of rope buckle technology. Utility Model Content

[0005] In order to solve the above technical problems, this application provides a self-locking rope buckle.

[0006] A self-locking rope buckle provided by this application adopts the following technical solutions:

[0007] A self-locking rope buckle includes a mounting plate, a mounting block arranged at the tip of the mounting plate, a connecting block arranged at the arc end of the mounting plate, a cover plate connected to the mounting block and the connecting block, a rope belt, a clamping block, and an adjusting rod connected to the clamping block; the number of the connecting blocks is two, and the two connecting blocks are symmetrically arranged on both sides of the mounting plate. The clamping block and the adjusting rod are both arranged between the two connecting blocks. The gap between the clamping block and the connecting block is a rope-passing channel, and the rope belt passes through the rope-passing channel. One end of the clamping block far from the adjusting rod is connected with a spring, and one end of the spring far from the clamping block is connected with the mounting block. On both sides of the clamping block close to the rope-passing channel, clamping serrations are arranged, and one end of the clamping serrations far from the clamping block inclines in the direction away from the adjusting rod.

[0008] By adopting the above technical solution, when tightening the rope belt, the user can push the self-locking rope buckle with two fingers, without the need for pressing operation, thus conveniently realizing the tightening adjustment of the rope belt. The single-handed operation improves the convenience of the user to adjust the rope belt. The self-locking rope buckle has good aesthetics and a thin, light and small volume, thus improving the user experience and comfort. By pressing the adjustment rod to drive the clamping block to move, the space of the rope passing channel between the clamping serrations and the connecting block is increased, thus facilitating the loosening adjustment of the rope belt. The obliquely arranged clamping serrations are convenient for guiding the rope belt when the rope belt is tightened, and reduce the phenomenon of loosening and slipping of the rope belt after adjustment, improving the stability of the rope belt limit locking.

[0009] Preferably, a first limiting groove is formed on the mounting block, one end of the spring close to the mounting block is located in the first limiting groove, a second limiting groove is formed on the clamping block, and one end of the spring close to the clamping block is located in the second limiting groove.

[0010] By adopting the above technical solution, the first limiting groove and the second limiting groove limit the telescopic direction of the spring, increasing the installation stability of the spring and the stability of the spring telescopic process, thus effectively reducing the situation of the spring offset or falling off during long-term use, and further improving the service life and use convenience of the rope buckle.

[0011] Preferably, a guide rod is arranged in the second limiting groove, and one end of the spring close to the clamping block is sleeved outside the guide rod.

[0012] By adopting the above technical solution, the guide rod further limits the telescopic direction of the spring, thus further reducing the phenomenon that the normal operation of the clamping block is affected by the unstable movement of the spring. At the same time, the guide rod can also enhance the compressive capacity and durability of the spring, which is beneficial to improving the overall performance of the self-locking rope buckle.

[0013] Preferably, a guide slide bar is arranged on the mounting plate, a guide chute is formed on one side of the clamping block close to the mounting plate, and the guide slide bar is slidably connected with the guide chute.

[0014] By adopting the above technical solution, the arrangement of the guide slide bar and the guide chute increases the stability of the clamping block during movement, reduces the phenomenon of the clamping block offset during movement, and thus improves the use stability of the self-locking rope buckle.

[0015] Preferably, a first clamping groove is formed on the connecting block, a second clamping groove is formed on the mounting block, a first clamping post and a second clamping post are fixedly arranged on the cover plate, the first clamping post is clamped with the first clamping groove, and the second clamping post is clamped with the second clamping groove.

[0016] By adopting the above technical solution, the cover plate is connected to the connection block through the first clamping post and to the mounting block through the second clamping post, making the installation process of the cover plate simple and convenient.

[0017] Preferably, two guiding blocks are arranged on the mounting plate, and the two guiding blocks are respectively arranged on both sides of the adjusting rod.

[0018] By adopting the above technical solution, the two guiding blocks limit and guide the moving direction of the adjusting rod, ensuring that the adjusting rod moves stably in a straight line direction and reducing the occurrence of the phenomenon that the effect of loosening the rope is affected due to the deviation of the adjusting rod.

[0019] Preferably, a first limiting block is arranged on the mounting plate, a second limiting block is arranged on the cover plate, limiting grooves are formed on one side of the first limiting block and the second limiting block close to the adjusting rod, and the adjusting rod is located between the two limiting grooves.

[0020] By adopting the above technical solution, the setting of the limiting grooves further restricts the moving range of the adjusting rod, ensuring that the adjusting rod always moves within a preset range, thereby reducing the occurrence of the phenomenon that the rope buckle fails or is damaged due to excessive movement of the adjusting rod.

[0021] Preferably, a pressing block is arranged at one end of the adjusting rod away from the clamping block.

[0022] By adopting the above technical solution, the pressing block is easy to identify and convenient for the user to perform a pressing operation. By pushing the pressing block, the adjusting rod can be easily controlled, and then the operation of loosening the rope can be completed, further improving the user experience.

[0023] Preferably, a pressure relief groove is formed on one side of the connection block close to the clamping saw teeth.

[0024] By adopting the above technical solution, the setting of the pressure relief groove reduces the wear of the rope belt during the adjustment process, thereby improving the service life of the rope belt.

[0025] Preferably, a rope threading loop is arranged on the cover plate.

[0026] By adopting the above technical solution, the setting of the rope threading loop enables the user to sew the self-locking rope buckle on the clothing, thereby improving the use flexibility of the self-locking rope buckle.
