A smoothly rotating sliding buckle assembly

Abstract

This utility model relates to a smoothly rotating sliding buckle assembly, comprising a base and two limiting members. The upper surface of the base has two mounting grooves, and the bottom of each limiting member has a rotating shaft. The limiting members are rotatably connected to the base via the mounting grooves and the rotating shafts. The opposing sides of the two limiting members are both arc-shaped surfaces, forming a channel between them for the chain teeth to slide. This utility model fundamentally improves the sliding environment of the chain teeth through the synergistic design of the rotatable limiting members and the arc-shaped channel. The two limiting members are rotatably connected to the base via the rotating shaft, and their angles can adaptively adjust according to the meshing rhythm and position changes of the chain teeth, avoiding rigid interference between existing fixed structures and the chain teeth. Simultaneously, the chain tooth channel formed by the arc-shaped surface is highly adapted to the arc-shaped contour of the chain teeth, transforming the point contact friction of traditional straight-edge channels into surface contact guidance, eliminating jamming points caused by sharp edges.

Description

Technical Field

[0001] This utility model relates to the field of sliding fasteners, and in particular to a sliding fastener assembly that rotates smoothly. Background Technology

[0002] The hoods of raincoats worn daily are usually secured to the main body with buttons, zippers, or a single integrated structure. However, raincoat hoods are typically large, and these securing methods limit their mobility. When cycling in winter, the hood cannot rotate synchronously with the head because the body cannot turn freely, obstructing the rider's left and right vision and making it difficult to observe road conditions, thus creating a traffic safety hazard.

[0003] Currently, hat-related technologies that can rotate synchronously with the head have emerged in the market. For example, invention patent application number 2024108495650 discloses a hat chain connection structure. This structure includes a fabric strap, with chain teeth fixedly connected to the lower end of the strap. A buckle is provided on the outside of the chain teeth, and a sliding buckle assembly is also provided on the outside of the chain teeth. A fixed buckle is provided at the front end of the sliding buckle assembly. When a user wears the hood, the hood can rotate synchronously with the head when the head is turned. The chain teeth slide relative to the sliding buckle assembly without pulling, making the hood highly mobile and easy to use. However, this connection structure still has shortcomings: the sliding groove of the sliding buckle assembly has an angular structure. Although the edges of the chain teeth are chamfered, the chain teeth are prone to jamming when passing through the sliding groove, resulting in less smooth rotation and a poor user experience. Summary of the Invention

[0004] This invention provides a sliding buckle assembly that rotates smoothly, addressing the problem of chain teeth easily getting stuck when passing through the sliding groove.

[0005] The present invention adopts the following technical solution:

[0006] A smoothly rotating sliding buckle assembly includes a base and two limiting members. The upper surface of the base is provided with two mounting grooves, and the bottom of the limiting members is provided with a pivot. The limiting members are rotatably connected to the base by inserting into the mounting grooves through the pivot. The opposite sides of the two limiting members are both arc surfaces, and a channel for the chain teeth to slide is formed between the two arc surfaces. The upper end of the arc surface of the limiting members is provided with a protruding edge, and a gap is reserved between the protruding edges for the fabric tape to pass through.

[0007] Furthermore, it also includes a female fastener for a snap fastener, and the base is provided with a female fastener part that engages with the female fastener for a snap-fit ​​connection.

[0008] Furthermore, a torsion spring is provided between the aforementioned rotating shaft and the inner wall of the aforementioned mounting groove to facilitate the reset of the aforementioned limiting member.

[0009] Furthermore, the width of the channel is 3-6mm, preferably 6mm.

[0010] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages:

[0011] 1. This utility model fundamentally improves the sliding environment of the chain teeth by using a rotatable limiting component and a circular arc surface channel in a coordinated design. The two limiting components are rotatably connected to the base via a rotating shaft, and can adaptively adjust their angles according to the meshing rhythm and position changes of the chain teeth, avoiding rigid interference between the existing fixed structure and the chain teeth; at the same time, the chain teeth channel formed by the circular arc surface is highly adapted to the arc contour of the chain teeth, transforming the point contact friction of the traditional straight edge channel into surface contact guidance, eliminating the jamming caused by sharp edges and corners.

[0012] 2. This utility model reduces the sliding resistance of the zipper teeth in the channel by more than 40% through the rotatable limiting component. Even in scenarios where the zipper is bent or under uneven force, it can still maintain smooth movement without jamming, significantly improving the user's operating experience.

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0017] Reference Figure 1 , Figure 2 A smoothly rotating sliding buckle assembly includes a base 1 and two limiting members 2. The upper surface of the base 1 is provided with two mounting grooves 10. The bottom of the limiting member 2 is provided with a rotating shaft 22. The limiting member 2 is rotatably connected to the base 1 by inserting into the mounting groove 10 through the rotating shaft 22. The opposite side of the two limiting members 2 is an arc surface 21. A channel 20 for the chain teeth 41 to slide is formed between the two arc surfaces 21. The upper end of the arc surface 21 of the limiting member 2 is provided with a protruding edge 23. A gap is reserved between the protruding edges 23 for the fabric belt 4 to pass through.

[0018] It also includes a female fastener 3 with a male and female fastener, and the base 1 is provided with a female fastener 11 that is engaged with the female fastener 3 for snap-fit ​​connection.

[0019] A torsion spring 101 is provided between the aforementioned rotating shaft 22 and the inner wall of the aforementioned mounting groove 10 to cause the aforementioned limiting member 2 to reset. One end of the torsion spring 101 is connected to the inner wall of the mounting groove 10, and the other end of the torsion spring 101 is connected to the rotating shaft 22. The elastic force of the torsion spring 101 restoring its deformation causes the limiting member 2 to reset until it is aligned with the side wall of the base 1 (see reference). Figure 2 This allows the zipper tape to be aligned with channel 20 and passed through.

[0020] The width of the channel 20 is 3-6mm, preferably 6mm.

[0021] Reference Figure 3 The zipper strap consists of a fabric strap 4 and a chain tooth row 41 located at the lower edge of the fabric strap 4. The fabric strap 4 is sewn to the lower edge of the hat, and the female buckle 3 is connected to the collar. The base 1 is fastened to the female buckle 3, facilitating the removal and installation of the hat. The fabric strap 4 passes through the aforementioned gap, and the chain tooth row 41 slides within the channel 20, allowing the hat to rotate very smoothly and providing the user with an excellent experience.

[0022] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
