Description

Technical Field

[0001] This utility model relates to the field of mushroom hook and loop fastener technology, and more specifically, to a mushroom hook and loop fastener with good wear resistance. Background Technology

[0002] Mushroom-shaped hook and loop fasteners are an openable closure system consisting of two plastic backing strips with mushroom-shaped plastic protrusions. The backing of the mushroom-shaped hook and loop fasteners can be customized with different adhesive backings or no adhesive backing. When the two pieces are pressed together, the mushroom heads lock into each other and make a sound. They can be easily disassembled, reused, and feature strong fastening, convenient opening and closing, and high strength. They can replace many traditional fasteners.

[0003] Currently, mushroom-shaped hook and loop fasteners undergo frequent opening and closing operations. During this process, the upper and lower mushroom-shaped protrusions press against each other and rub against each other. With repeated use and significant friction, the mushroom-shaped protrusions are prone to wear, severely affecting the lifespan of the hook and loop fasteners. Therefore, we propose a mushroom-shaped hook and loop fastener with improved wear resistance. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a mushroom-shaped hook and loop fastener with good wear resistance, so as to solve the technical problem that the mushroom heads will squeeze and rub against each other during the opening and closing operation of the current mushroom hook and loop fastener, which will cause wear on the mushroom heads and affect the service life of the mushroom hook and loop fastener.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mushroom-shaped fastener with good wear resistance, comprising a lower mushroom mechanism and an upper mushroom mechanism that snaps onto the lower mushroom mechanism. The lower mushroom mechanism includes a lower base band, a lower connecting band is provided on the lower base band, and a lower mushroom buckle is provided at the upper end of the lower connecting band. The lower mushroom buckle includes a lower mushroom stem and a lower mushroom head provided at the upper end of the lower mushroom stem. The upper mushroom mechanism includes an upper base band, an upper connecting band is provided at the lower end of the upper base band, and an upper mushroom buckle is provided at the lower end of the upper connecting band. The upper mushroom buckle includes an upper mushroom stem and an upper mushroom head provided at the lower end of the upper mushroom stem.

[0006] Preferably, the lower mushroom stem is provided with a first curved portion and a second curved portion in sequence along its long axis, and the arrangement of the first curved portion and the second curved portion forms an S-shape for the lower mushroom stem as a whole.

[0007] Preferably, the upper end of the lower mushroom head is provided with a buffer groove, the buffer groove is cross-shaped, and a spherical groove is provided at the center of the buffer groove.

[0008] Preferably, the upper end of the lower mushroom head is provided with a guide opening at the upper part of the buffer groove, and the guide opening is wide and opens outward from bottom to top.

[0009] Preferably, the upper cross-section of the upper mushroom head is elliptical, the upper mushroom head gradually decreases in size from top to bottom, and the lower end of the upper mushroom head is spherical.

[0010] Preferably, a fixing rod is provided on the side end of the upper mushroom stem. The fixing rod is L-shaped, and a compression ball is provided at the end of the fixing rod. The compression ball is located in a spherical groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of a lower mushroom stem and buffer groove structure, innovatively designs the lower mushroom stem in an S-shape, possessing unique elastic deformation capabilities. During frequent opening and closing operations, whether it is the pressure generated by the upper mushroom buckle or the pulling force applied during disassembly, the S-shaped lower mushroom stem can cleverly buffer these forces through its own deformation, greatly reducing the friction force on the mushroom head. At the same time, the cross-shaped buffer groove at the upper end of the lower mushroom head allows the upper part of the lower mushroom head to deform inward when the upper and lower mushroom heads are pressed against each other, thereby reducing the friction between the upper and lower mushroom heads. With the cooperation of both, the wear degree of the mushroom head is significantly reduced, greatly improving the overall wear resistance of the mushroom hook and loop fastener and effectively extending its service life. This saves users the cost and effort of frequently replacing the hook and loop fastener, solving the problem that the mushroom heads are pressed against each other and generate friction during the opening and closing operations of current mushroom hook and loop fasteners, causing wear on the mushroom head and affecting the service life of the mushroom hook and loop fastener.

[0013] 2. This utility model also incorporates a squeeze ball and a spherical groove structure. After the squeeze ball enters the spherical groove, it not only adds extra fastening force to the mushroom-shaped hook and loop fastener connection, but also expands the lower mushroom head, preventing the buffer groove from affecting the locking ability of the lower mushroom head. This ensures that the mushroom-shaped hook and loop fastener can maintain a stable connection and avoids the problem of items falling off due to loose connection. Attached Figure Description

Detailed Implementation

[0020] like Figures 1 to 5 As shown, this utility model relates to a mushroom-shaped fastener with good wear resistance, including a lower mushroom mechanism 100 and an upper mushroom mechanism 200 snapped onto the lower mushroom mechanism 100. The lower mushroom mechanism 100 includes a lower base belt 101, a lower connecting belt 102 is provided on the lower base belt 101, a lower mushroom buckle 103 is provided at the upper end of the lower connecting belt 102, the lower mushroom buckle 103 includes a lower mushroom stem 104 and a lower mushroom head 105 provided at the upper end of the lower mushroom stem 104. The upper mushroom mechanism 200 includes an upper base belt 201, an upper connecting belt 202 is provided at the lower end of the upper base belt 201, an upper mushroom buckle 203 is provided at the lower end of the upper connecting belt 202, and the upper mushroom buckle 203 includes an upper mushroom stem 204 and an upper mushroom head 205 provided at the lower end of the upper mushroom stem 204. This invention can greatly reduce the friction on the mushroom head, significantly reduce the wear of the mushroom head, thereby greatly improving the overall wear resistance of the mushroom-shaped buckle and effectively extending its service life, saving users the cost and effort of frequently replacing buckles.

[0021] Specifically, the lower mushroom stem 104 has a first curved portion 1041 and a second curved portion 1042 arranged sequentially along its long axis. The arrangement of the first curved portion 1041 and the second curved portion 1042 forms an S-shape for the lower mushroom stem 104 as a whole. The lower mushroom stem 104 is innovatively designed in an S-shape, possessing a unique elastic deformation capability. In frequent opening and closing operations, whether it is the pressure generated by the upper mushroom buckle 203 or the pulling force applied during disassembly, the S-shaped lower mushroom stem 104 can cleverly buffer these forces through its own deformation, greatly reducing the friction force on the mushroom head.

[0022] Furthermore, a buffer groove 1051 is provided at the upper end of the lower mushroom head 105. The buffer groove 1051 is cross-shaped, and a spherical groove 1052 is provided at the center of the buffer groove 1051. The cross-shaped buffer groove 1051 provided at the upper end of the lower mushroom head 105 allows the upper part of the lower mushroom head 105 to deform inward when the upper and lower mushroom heads are pressed against each other, thereby reducing the friction between the upper mushroom head 205 and the lower mushroom head 105.

[0023] It is worth noting that the upper end of the lower mushroom head 105 is provided with a guide opening 1053 located above the buffer groove 1051. The guide opening 1053 is wide and opens outward from bottom to top. During the process of the extrusion ball 207 descending and inserting into the spherical groove 1052, the guide opening 1053 can guide the extrusion ball 207, so that the extrusion ball 207 can smoothly enter the spherical groove 1052.

[0024] It is worth mentioning that the upper mushroom head 205 has an elliptical cross-section at the top, gradually decreasing in size from top to bottom, and the lower end of the upper mushroom head 205 is spherical. The elliptical upper mushroom head 205, which gradually decreases in size from top to bottom, can adapt to the shape of the lower mushroom stem 104, allowing the lower mushroom stem 104 to limit the upper mushroom head 205.

[0025] It is worth noting that a fixing rod 206 is provided on the side end of the upper mushroom stem 204. The fixing rod 206 is L-shaped, and a compression ball 207 is provided at the end of the fixing rod 206. The compression ball 207 is located in the spherical groove 1052. After the compression ball 207 enters the spherical groove 1052, it not only adds extra fastening force to the mushroom hook and loop connection, but also expands the lower mushroom head 105, preventing the buffer groove 1051 from affecting the locking ability of the lower mushroom head 105, so that the mushroom hook and loop can maintain a stable connection state.

[0026] Working Principle: This embodiment provides a mushroom-shaped fastener with good wear resistance. In use, the upper mushroom mechanism 200 and the lower mushroom mechanism 100 are connected. When the upper mushroom head 205 approaches the lower mushroom head 105, it enters between the upper and lower mushroom heads 105 through compression, locking the upper and lower mushroom heads. During the compression process of the upper mushroom head 205, the lower mushroom head 105 can deform from the outside to the center under the action of the buffer groove 1051, effectively reducing the compression of the lower mushroom head 105 by the upper mushroom head 205. The S-shaped lower mushroom stem 104 can deform outwards, further reducing the friction of the snap-fit. When the upper and lower mushroom heads are locked, the compression ball 207 can descend and insert into the spherical groove 1052. During this process, the guide port 1053 can guide the compression ball 207. The compression ball 207, located in the spherical groove 1052, can expand the lower mushroom head 105, ensuring the locking ability of the lower mushroom head 105 and improving the connection stability. When the mushroom hook and loop fastener is disassembled, the lower mushroom head 105 will be compressed. The S-shaped lower mushroom stem 104 can buffer the force through its own elastic deformation, increasing the distance between the lower mushroom heads 105, thereby reducing the wear of the upper and lower mushroom heads and improving the overall wear resistance and service life of the mushroom hook and loop fastener.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
