Description

Technical Field

[0001] The utility model relates to the technical field of five-claw buttons, in particular to a five-claw button with stable opening and closing force. Background Art

[0002] Stainless steel five-prong buttons offer the best value among metal buttons. Their high hardness, long service life, and corrosion resistance have earned them a reputation for quality and affordability. Despite their industry-wide success over two decades, they continue to suffer from issues such as inconsistent opening and closing force. This significant variation in opening and closing force has currently discouraged high-end brand customers from using stainless steel five-prong buttons. The main drawbacks of existing stainless steel five-prong buttons are:

[0003] The gaps between the two adjacent spring pieces of the existing stainless steel five-claw button are tightly connected without any gaps. They influence and restrict each other and cannot move freely independently, resulting in impaired rebound force, tight initial opening and closing force, and continuous decrease in subsequent opening and closing force. Therefore, the present application proposes a five-claw button that can provide stable opening and closing force. Utility Model Content

[0004] The purpose of the present invention is to provide a five-claw button with stable opening and closing force to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a five-claw button with stable opening and closing force, comprising a female buckle and a male buckle cooperating with the female buckle, a snap-fitting protrusion is provided at the axis of the male buckle, a snap-fitting interface cooperating with the snap-fitting protrusion is provided at the axis of the female buckle, an annular snap-fitting metal sheet is provided around the snap-fitting interface on the female buckle, a plurality of punching grooves are evenly provided on the annular snap-fitting metal sheet along the circumferential direction, and the annular snap-fitting metal sheet is evenly divided into a plurality of spring pieces by the plurality of punching grooves.

[0006] Wherein, the width of the punching groove is 0.3 mm.

[0007] Wherein, the surface of the clamping protrusion is provided with an annular groove which cooperates with the plurality of elastic sheets.

[0008] Wherein, the female buckle is provided with a first five-claw fastener, and the female buckle is clamped and fixed on the fabric by the first five-claw fastener.

[0009] Wherein, the male buckle is provided with a second five-claw fastener, and the male buckle is clamped and fixed on the fabric by the second five-claw fastener.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model divides the annular clamping metal sheet into multiple equal elastic sheets, and a punching groove is formed between two adjacent elastic sheets, so that there is enough space between two adjacent elastic sheets for separation and relative independence, and the two adjacent elastic sheets do not affect each other, which provides good conditions for the stability of the resilience of the elastic sheet. When the male buckle is buckled or separated, the elastic sheet (resilience) on the female buckle can return or open freely, and the return process is not affected by the connected elastic sheets. Therefore, the opening and closing force will be consistent, ensuring stable force and extending the service life at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Please refer to Figures 1-9, the present utility model provides a technical solution: a five-claw button with stable opening and closing force, including a female button 30 and a male button 40 that cooperates with the female button 30. A clamping protrusion is provided at the axis of the male button 40, and a clamping interface that cooperates with the clamping protrusion is provided at the axis of the female button 30. An annular clamping metal sheet is provided around the clamping interface on the female button 30. A plurality of punching grooves 31 are evenly arranged along the circumferential direction on the annular clamping metal sheet. The punching groove 31 can be any one of 2-10. The annular clamping metal sheet is evenly divided into a plurality of elastic pieces 32 through the plurality of punching grooves 31. The elastic piece 32 can be any one of 2-10. The number of elastic pieces 32 is the same as the number of punching grooves 31. When the male button 40 and the female button 30 need to be assembled together, the clamping protrusion on the male button 40 is inserted into the clamping interface of the female button, and the annular clamping metal sheet is divided into a plurality of equal elastic pieces 32, and a punching groove 31 is formed between two adjacent elastic pieces 32, so that there is enough space between two adjacent elastic pieces 32 for separation, relatively independent, and two adjacent elastic pieces 32 do not affect each other, which provides good conditions for the stability of the elastic force of the elastic piece 32. When the male button 40 is fastened or separated, the elastic pieces 32 (resilience) on the female button 30 can all freely return to their positions or open, and the return process is not affected by the connected elastic pieces 32. Therefore, the opening and closing force will remain consistent. On the premise of ensuring stable force, the service life is also extended.

[0024] Among them, the width dimension of the punching groove 31 is 0.3 mm. The adjacent elastic pieces 32 are separated by the punching groove 31, so that there is enough space between two adjacent elastic pieces 32 for separation, relatively independent, and two adjacent elastic pieces 32 do not affect each other, which provides good conditions for the stability of the elastic force of the elastic piece 32.

[0025] Among them, an annular groove that cooperates with a plurality of elastic pieces 32 is provided on the surface of the clamping protrusion. After the clamping protrusion on the male button 40 is inserted into the clamping interface of the female button, the plurality of elastic pieces 32 are stuck at the annular groove, so that the male button 40 is fastened on the female button 30.

[0026] Among them, a first five-claw fastener 10 is provided on the female button 30. The female button 30 is clamped and fixed on the fabric through the first five-claw fastener 10. When assembling the female button 30, the female button 30 and the first five-claw fastener 10 are respectively located on both sides of the fabric, and then the first five-claw fastener 10 is pressed on the female button 30, so that the female button 30 is clamped and fixed on the fabric through the first five-claw fastener 10.

[0027] Among them, a second five-claw fastener 20 is provided on the male button 40. The male button 40 is clamped and fixed on the fabric through the second five-claw fastener 10. When assembling the male button 40, the male button 40 and the second five-claw fastener 20 are respectively located on both sides of the fabric, and then the second five-claw fastener 20 is pressed on the male button 40, so that the male button 40 is clamped and fixed on the fabric through the second five-claw fastener 10.

[0028] Working principle: When in use, the female buckle 30 and the first five-claw fastener 10 are respectively located on both sides of the fabric. Then, the first five-claw fastener 10 is pressed onto the female buckle 30, so that the female buckle 30 is clamped and fixed on the fabric through the first five-claw fastener 10. The male buckle 40 and the second five-claw fastener 20 are respectively located on both sides of the fabric. Then, the second five-claw fastener 20 is pressed onto the male buckle 40, so that the male buckle 40 is clamped and fixed on the fabric through the second five-claw fastener 10. Then, the clamping protrusion on the male buckle 40 is inserted into the clamping port of the female buckle, and a plurality of elastic pieces 32 are stuck in the annular groove, so that the male buckle 40 is buckled onto the female buckle 30, thereby buckling the male buckle 40 and the female buckle 30 together.

[0029] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
