Description

Technical Field

[0001] This utility model relates to the field of sliding buckles, and in particular to an adjustable sliding buckle assembly and chain. Background Technology

[0002] The hoods of everyday cotton-padded coats are usually secured to the main body of the coat with buttons, zippers, or an integrated structure. However, the hoods of cotton-padded coats are typically large, and these securing methods limit their mobility. When cycling in winter, because the body cannot move freely with the head, the hood cannot rotate synchronously with the head, obstructing the rider's left and right vision and greatly hindering their ability to observe road conditions, thus creating a traffic safety hazard.

[0003] Currently, hat-related technologies that allow for synchronized head rotation 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 its lower end. A buckle is located on the outside of the chain teeth, and a sliding buckle assembly is also located on the outside of the chain teeth. A fixed buckle is located at the front end of the sliding buckle assembly. When a user wears the hood, the hood rotates synchronously with the head, and the chain teeth slide relative to the sliding buckle assembly without pulling. The hood has high mobility and is easy to use. However, this connection structure still has shortcomings: the width of the sliding groove of the sliding buckle assembly cannot be adjusted, meaning the sliding buckle assembly can only match a single size of chain teeth. This results in poor structural design flexibility. If the chain tooth size is larger than the groove width, a new mold needs to be created, which increases mold costs and causes manufacturing difficulties for manufacturers. Summary of the Invention

[0004] This utility model provides an adjustable sliding buckle assembly and chain belt to solve the problems of the above-mentioned sliding buckle assembly, such as the inability to adjust the width of the sliding groove and poor structural flexibility.

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

[0006] An adjustable sliding fastener assembly includes a slider, a base, and a back plate arranged in sequence. The slider and the base have a groove in the middle of their opposite sides for a mating chain tooth to pass through. A gap is reserved between the upper end of the slider and the upper end of the base. The lower end of the base has a groove, and the lower end of the slider has a protrusion that fits the groove. The upper surface of the protrusion has multiple equally spaced limiting grooves that are connected in sequence in a wave shape. The upper wall of the groove has a protrusion that fits the limiting groove near the groove opening. The protrusion is interference-fitted into the limiting groove. The base is detachably connected to the back plate.

[0007] Furthermore, magnets are embedded in both the base and the back plate, and the base is connected to the back plate via the magnets.

[0008] Furthermore, the aforementioned base is connected to the aforementioned back plate via a snap-fit ​​structure.

[0009] Furthermore, the upper surface of the aforementioned protrusion is provided with eight, nine, or ten limiting grooves.

[0010] Furthermore, the aforementioned slider has a circular cross-section, and the front edge of the slider has a chamfered structure.

[0011] A chain belt includes a fabric belt and a chain tooth row disposed at the lower edge of the fabric belt. The chain tooth row consists of a plurality of chain teeth arranged at equal intervals. A plurality of the aforementioned adjustable sliding buckle assemblies are fitted on the chain tooth row. The chain tooth row passes through the aforementioned sliding groove, and the fabric belt passes through the aforementioned gap.

[0012] 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:

[0013] 1. This utility model's sliding buckle assembly, by incorporating an adjustable sliding groove structure, achieves dynamic adaptation of the groove width, enabling it to match different sizes and models of chain teeth (e.g., chain tooth width differences within a range of 2-5mm are compatible). This completely overcomes the limitation of existing sliding buckle assemblies that can only adapt to a single specification of chain teeth. The same sliding buckle assembly can be widely used in the connection structures of different styles and sizes of cotton clothing and hats, significantly improving the universal adaptability of components and reducing the component adaptation costs caused by product model iterations.

[0014] 2. The sliding buckle assembly of this utility model achieves adjustable sliding groove while retaining the smooth sliding characteristics of chain teeth and sliding buckle assembly. When the user turns their head in scenarios such as cycling, the hat can rotate synchronously through the relative sliding of chain teeth and sliding buckle, effectively avoiding obstruction of vision; and the sliding process is smooth without jamming or pulling, which not only solves traffic safety hazards, but also improves wearing comfort.

[0015] 3. Magnets are embedded in both the base and the back plate of this utility model. The base is connected to the back plate through the magnets, so that the position of the sliding buckle assembly on the collar can be adjusted arbitrarily. Users can adjust it according to their own habits, so that the hat can rotate smoothly and bring a better user experience. Attached Figure Description

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] Reference Figures 1-5 An adjustable sliding buckle assembly includes a slider 1, a base 2, and a back plate 3 arranged in sequence. The slider 1 and the base 2 have a groove 20 in the middle of their opposing surfaces, through which a chain tooth 42 passes. A gap 10 is reserved between the upper end of the slider 1 and the upper end of the base 2. The lower end of the base 2 has a groove 22. The lower end of the slider 1 has a protrusion 11 that matches the groove 22. The upper surface of the protrusion 11 has multiple equally spaced limiting grooves 110. The limiting grooves 110 are connected in sequence in a wave shape. The upper wall of the groove 22 has a ridge 21 that matches the limiting groove 110 near the groove opening. The ridge 21 is interference-fitted into the limiting groove 110. After the ridge 21 is interference-fitted into the limiting groove 110, the groove width is not easily changed and is not affected by the rolling of the chain tooth 42. The base 2 is detachably connected to the back plate 3.

[0024] Reference Figure 4 Magnets 31 are embedded in both the base 2 and the back plate 3, and the base 2 is connected to the back plate 3 through the magnets 31.

[0025] Reference Figure 4 The upper surface of the aforementioned protrusion 11 is provided with eight, nine, or ten limiting grooves 110, preferably nine limiting grooves 110, each limiting groove 110 corresponding to a gear position, as shown in the reference. Figure 2 In the direction of arrow a, adjust the width of the slide 20 to accommodate different widths of the chain teeth 42.

[0026] Reference Figure 1 The cross-section of the aforementioned slider 1 is circular, and the front edge of slider 1 has a chamfered structure.

[0027] Reference Figure 4 , Figure 6 A chain belt 4 includes a fabric belt 41 and a chain tooth row located at the lower edge of the fabric belt 41. The fabric belt is sewn to the lower edge of the hat. The collar clip is located between the base 2 and the back plate 3. The chain tooth row consists of a plurality of chain teeth 42 arranged at equal intervals. Several adjustable sliding buckle assemblies are fitted on the chain tooth row. The distance between the chain teeth 42 is less than the length of the sliding groove 20. The chain tooth row passes through the sliding groove 20, and the fabric belt 41 passes through the gap 10.

[0028] 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.
