[0002] Metal snap buttons, typically made of metal, are commonly used on clothing, bags, and other textiles. They consist of four parts: two buttons and two corresponding buckles, which physically close and secure the buttons. These buttons are widely used for their durability and strength.

[0003] In the existing technology, each use of a button applies a certain amount of mechanical stress. Long-term stress can lead to metal fatigue, especially at the button's joints. This fatigue causes the metal to gradually lose its elasticity and strength, increasing the risk of wear and failure. Therefore, a wear-resistant metal four-piece button has been proposed to address this issue. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a wear-resistant metal four-piece button, which aims to improve the problem in the existing technology that long-term stress will cause metal fatigue, resulting in the gradual loss of elasticity and strength of the button's connecting parts.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1 - Figure 2 、 Figure 4 The utility model provides an embodiment: an anti-wear metal four-piece button, including a button cap 1 and a button base 2. The surface of the button cap 1 is fixedly connected to a rubber seat 12 by a bolt 11. The button cap 1 serves as the upper part of the button and is used to be fixed on the surface of an object. The presence of the rubber seat 12 helps to reduce the wear on the surface of the button cap 1 caused by direct friction, while increasing the comfort during operation. A socket 21 is provided on the surface of the button base 2, and a plurality of groups of slots 22 distributed in an array are provided on the inner wall of the socket 21. The socket 21 provides a fixed position for the insertion rod 32 to ensure the correct docking of the button cap 1 and the button base 2. The slots 22 on the inner wall of the socket 21 help ensure the stable insertion and fixation of the insertion rod 32, thereby enhancing the closing strength and durability of the button.

[0029] Reference Figure 2 - Figure 3 The bottom surface of the buckle cap 1 is provided with a connecting assembly 3, which is used to connect the buckle cap 1 and the buckle base 2. The connecting assembly 3 includes a collar 31, and an insert rod 32 is slidably connected to the inside of the collar 31. The collar 31 is used to surround the insert rod 32 and allow the insert rod 32 to move in the vertical direction. The side wall of the collar 31 is provided with multiple groups of array-distributed limiting grooves 33, and the limiting grooves 33 are internally slidably connected to limiting blocks 34. The limiting blocks 34 are fixedly connected to the outer wall of the insert rod 32. The mutual cooperation between the limiting grooves 33 and the limiting blocks 34 ensures the stability of the insert rod 32 in the collar 31. The insert rod 32 is adapted to the shape of the socket 21. The insert rod 32 is used to be inserted into the socket 21, thereby connecting to the buckle base 2. A transverse groove 35 and a vertical groove 36 are provided inside the insertion rod 32, and the transverse groove 35 and the vertical groove 36 are connected to each other. The transverse groove 35 is used to provide a track for the movement of two groups of wedge blocks 37, so that the wedge blocks 37 can move laterally along the inner wall of the transverse groove 35. Two groups of symmetrically arranged wedge blocks 37 are slidably connected inside the transverse groove 35. The wedge blocks 37 are adapted to the shape of the slot 22. The wedge blocks 37 are used to be inserted into the interior of the slot 22 to provide a fixing effect for the insertion rod 32 to prevent the insertion rod 32 from falling off after entering the socket 21. The two groups of wedge blocks 37 are elastically connected by a return spring 38. The return spring 38 provides elastic support to the two groups of wedge blocks 37, so that the two groups of wedge blocks 37 move back to back, ensuring the stability and long-term durability of the wedge blocks 37 in the slot 22.

[0030] Reference Figure 3 A linkage rod 39 is slidably connected to the interior of the vertical slot 36, providing space for the linkage rod 39 and the hinged rod 310 to move. The top of the linkage rod 39 is fixedly connected to the button cap 1. The linkage rod 39 is responsible for transmitting the operating force to release the button. Both sides of the linkage rod 39 are hingedly connected to the hinged rods 310, which are hingedly connected to the surface of the wedge 37. By pulling the button cap 1, the linkage rod 39 moves one end of the two sets of hinged rods 310 upward, while the other ends drive the two sets of wedges 37 to move backward, causing the return spring 38 to compress, separating the wedge 37 from the slot 22 and withdrawing the insertion rod 32 from the receptacle 21, thus achieving button release.

[0031] Working principle: When the user needs to close the button, he only needs to align the button cap 1 with the button base 2, and then press the button cap 1 to insert the insertion rod 32 into the insertion hole 21. Since the shape of the insertion rod 32 is adapted to the insertion hole 21, the insertion rod 32 can be smoothly inserted into the insertion hole 21. At the same time, since the interior of the insertion rod 32 is provided with a transverse groove 35 and a vertical groove 36, the transverse groove 35 provides a moving track for the wedge block 37, so that the wedge block 37 can move laterally along the inner wall of the transverse groove 35. During the insertion process, the wedge block 37 will automatically slide into the slot 22. Since the wedge block 37 is adapted to the shape of the slot 22, the wedge block 37 can be firmly stuck in the slot 22, thereby ensuring the stability of the insertion rod 32 in the slot 21. The return spring 38 provides elastic support for the wedge block 37, so that the wedge block 37 remains stable in the slot 22, thereby enhancing the closing strength and durability of the button.

[0032] When the user needs to open the button, he only needs to pull the button cap 1, and the linkage rod 39 will move one end of the two sets of hinged rods 310 upward, and the other end will drive the two sets of wedges 37 to move backward. The wedges 37 will separate from the slots 22, so that the insertion rod 32 can be pulled out of the socket 21, and the button can be detached.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
