Description

Technical Field

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

[0002] Mushroom-shaped Velcro is a common fastener consisting of a mushroom-shaped male buckle and a female buckle that interlocks with it. It achieves connection through the interlocking of the mushroom heads, and is characterized by its ease of use and repeatable opening and closing. It is widely used in clothing, bags, home furnishings, automotive interiors, and other fields, enabling the quick connection and separation of components, replacing traditional zippers, buttons, and other fasteners, and bringing great convenience to people's lives and production.

[0003] Currently, mushroom-shaped hook and loop fasteners only lock together via their mushroom-shaped ends. However, this lack of stability under complex external forces means that the fasteners are prone to loosening or even detaching under conditions of frequent clothing wear and movement, or when bags are carrying heavy loads. This affects normal use and limits the application of mushroom-shaped hook and loop fasteners in scenarios requiring stringent connection stability. Therefore, we propose a highly stable mushroom-shaped hook and loop fastener. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a highly stable mushroom-shaped hook and loop fastener to solve the technical problem that the current hook and loop fasteners, which rely solely on the mushroom heads for interlocking, are not stable enough when faced with complex external forces, thus limiting their application in scenarios with stringent requirements for connection stability.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a highly stable mushroom-shaped hook and loop fastener, comprising a lower hook and loop mechanism and an upper hook and loop mechanism that snaps onto the lower hook and loop mechanism. The lower hook and loop mechanism includes a first base band, and the upper hook and loop mechanism includes a second base band. A connecting layer is provided at the upper end of the first base band and the lower end of the second base band. Lower mushroom-shaped hooks are arrayed at the upper end of the connecting layer of the first base band, and upper mushroom-shaped hooks are arrayed at the lower end of the connecting layer of the second base band. The upper mushroom-shaped hooks snap onto the four lower mushroom-shaped hooks.

[0006] Preferably, a first buffer layer is provided on the upper end of the connection layer of the first baseband, the first buffer layer is located between the lower mushroom buckles, and the first buffer layer is located directly below the upper mushroom buckle.

[0007] Preferably, a second buffer layer is provided at the lower end of the connection layer of the second baseband. The second buffer layer is located between the upper mushroom buckles. Buffer grooves are provided at the upper end of the first buffer layer and the lower end of the second buffer layer. The second buffer layer is located directly below the lower mushroom buckle.

[0008] Preferably, the upper mushroom buckle includes a second mushroom stem and a second mushroom head disposed at the lower end of the second mushroom stem. The lower end of the second mushroom head is located in the buffer groove of the first buffer layer, and the outer surface of the second mushroom head is arrayed with limiting balls.

[0009] Preferably, the lower mushroom buckle includes a first mushroom stem and a first mushroom head disposed at the upper end of the first mushroom stem. The upper end of the first mushroom head is located in the buffer groove of the second buffer layer, and the outer surface of the first mushroom stem is provided with positioning grooves corresponding to the limiting ball.

[0010] Preferably, the upper end of the second mushroom head is provided with a limiting ring, the limiting ring is made of rubber, and the cross-section of the limiting ring gradually decreases from bottom to top in a stepped distribution. The lower end of the first mushroom head is provided with a limiting groove array, the limiting groove is set as an arc along the long axis direction, the arc center of the limiting groove matches the circle center of the limiting ring, and the shape of the limiting groove cross-section is adapted to the cross-sectional shape of the limiting ring.

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

[0012] 1. This utility model, through the design of upper and lower mushroom-shaped buckle structures, and the unique structure of "one upper mushroom-shaped buckle snapping between four lower mushroom-shaped buckles", combined with the precise engagement of the limiting ball and the positioning groove, and the tight nesting of the rubber limiting ring and the limiting groove, makes the mushroom-shaped hook and loop fastener not only locked by the mushroom head, but also comprehensively enhance the stability of the hook and loop connection from the horizontal and vertical directions, and even from various angles. It prevents the mushroom-shaped hook and loop fastener from easily loosening and falling off when faced with complex external forces. It can meet the needs of scenarios with high requirements for connection stability, and solves the problem that the current method of locking the mushroom heads together is not stable enough when faced with complex external forces, which limits the application of the mushroom-shaped hook and loop fastener in scenarios with strict requirements for connection stability.

[0013] 2. This utility model also incorporates a limiting ring and limiting groove structure. The limiting groove is arc-shaped, allowing the limiting ring to engage with multiple limiting grooves at once. The stepped structure provides an effective anti-detachment mechanism in multiple directions. The stepped shape also aids in self-positioning and calibration during engagement. The stepped shape of the limiting ring and limiting groove increases the contact area and engagement depth of the engagement. Furthermore, when subjected to external force, each step can share a portion of the tensile or shear force, thereby greatly improving the overall stability of the connection and significantly enhancing the vertical connection strength of the upper and lower mushroom-shaped buckles. This effectively prevents the buckle from coming undone under vertical tension, making the connection more secure. Attached Figure Description

Detailed Implementation

[0023] like Figures 1 to 8 As shown, this utility model relates to a highly stable mushroom-shaped hook and loop fastener, comprising a lower hook and loop mechanism 100 and an upper hook and loop mechanism 200 engaged with the lower hook and loop mechanism 100. The lower hook and loop mechanism 100 includes a first base band 101, and the upper hook and loop mechanism 200 includes a second base band 201. A connecting layer 102 is provided at the upper end of the first base band 101 and the lower end of the second base band 201. Lower mushroom-shaped hooks 104 are arranged in an array at the upper end of the connecting layer 102 of the first base band 101, and upper mushroom-shaped hooks 202 are arranged in an array at the lower end of the connecting layer 102 of the second base band 201. The upper mushroom-shaped hooks 202 are engaged between the four lower mushroom-shaped hooks 104. This utility model enhances the stability of the hook and loop connection not only through the mushroom head locking mechanism but also through multiple locking actions from horizontal and vertical directions, and even from various angles, preventing the hook and loop fastener from easily loosening and detaching under complex external forces. This meets the requirements for scenarios with high connection stability.

[0024] Specifically, a first buffer layer 103 is provided on the upper end of the connecting layer 102 of the first baseband 101. The first buffer layer 103 is located between the lower mushroom buckles 104 and directly below the upper mushroom buckle 202. The first buffer layer 103 is provided for pressure buffering of the upper mushroom buckle 202.

[0025] Furthermore, a second buffer layer 203 is provided at the lower end of the connecting layer 102 of the second baseband 201. The second buffer layer 203 is located between the upper mushroom buckles 202. Buffer grooves 105 are provided at the upper end of the first buffer layer 103 and the lower end of the second buffer layer 203. The second buffer layer 203 is located directly below the lower mushroom buckle 104. The second buffer layer 203 is provided for buffering the lower mushroom buckle 104.

[0026] It is worth noting that the upper mushroom buckle 202 includes a second mushroom stem 2021 and a second mushroom head 2022 disposed at the lower end of the second mushroom stem 2021. The lower end of the second mushroom head 2022 is located within the buffer groove 105 of the first buffer layer 103, and the outer surface of the second mushroom head 2022 is arrayed with limiting balls 2024. When the buckle is subjected to pressure, the presence of the buffer groove 105 allows the first buffer layer 103 and the second buffer layer 203 to undergo a certain degree of elastic deformation, absorbing and dispersing part of the impact force, and preventing the mushroom buckle from being damaged due to excessive instantaneous pressure.

[0027] It is worth noting that the lower mushroom-shaped latch 104 includes a first mushroom stem 1041 and a first mushroom head 1042 disposed at the upper end of the first mushroom stem 1041. The upper end of the first mushroom head 1042 is located within the buffer groove 105 of the second buffer layer 203. The outer surface of the first mushroom stem 1041 is arrayed with positioning grooves 1044 corresponding to the limiting ball 2024. When the mushroom-shaped latches are engaged, the limiting ball 2024 can engage within the positioning groove 1044, which can initially define the position of the mushroom-shaped latches.

[0028] It is worth noting that the upper end of the second mushroom head 2022 is provided with a limiting ring 2023. The limiting ring 2023 is made of rubber. The cross-section of the limiting ring 2023 decreases from bottom to top in a stepped distribution. The lower end of the first mushroom head 1042 is provided with a limiting groove 1043. The limiting groove 1043 is set as an arc along the long axis. The center of the arc of the limiting groove 1043 matches the center of the circle of the limiting ring 2023. The shape of the cross-section of the limiting groove 1043 is adapted to the cross-sectional shape of the limiting ring 2023. The limiting groove 1043 is arc-shaped, allowing the limiting ring 2023 to be engaged in multiple limiting grooves 1043 at once. The stepped structure provides an effective anti-disengagement mechanism in multiple directions. The stepped shape also helps with self-positioning and calibration during engagement. The stepped shape of the limiting ring 2023 and the limiting groove 1043 also increases the contact area and engagement depth of the mutual engagement. Furthermore, when subjected to external force, each step can share a portion of the tensile or shear force, thereby greatly improving the overall stability of the connection.

[0029] Working principle: This embodiment provides a highly stable mushroom-shaped hook and loop fastener. In use, align the upper mushroom-shaped hook and loop fastener 202 of the upper hook and loop mechanism 200 with the lower hook and loop mechanism 100. The mushroom-shaped hooks are distributed such that one upper mushroom-shaped hook and loop 202 is located in the gap between four lower mushroom-shaped hook and loop fasteners 104. Then, apply appropriate pressure downwards. The second mushroom rod 2021 and the second mushroom head 2022 move downwards. Under the action of the mushroom arc surface, the second mushroom head 2022 can enter between the four first mushroom heads 1042. Further descent allows the second mushroom head 2022 to... The lower end of the second mushroom head 2022 enters the buffer groove 105 of the first buffer layer 103. The limiting balls 2024 arrayed on the outer surface of the second mushroom head 2022 will precisely engage with the positioning groove 1044 pre-set on the outer surface of the first mushroom rod 1041 of the lower mushroom buckle 104 as the second mushroom head 2022 descends. This action achieves a preliminary limiting effect, effectively preventing relative displacement between the upper mushroom buckle 202 and the lower mushroom buckle 104 in the horizontal direction. Simultaneously, the upper end of the first mushroom head 1042 will enter the second buffer... Within the buffer groove 105 of layer 203, the upper buckle mechanism 200 continues to be pressed down. Under the action of the buffer layer, it can continue to descend a little further. Since the limiting ring 2023 set at the upper end of the second mushroom head 2022 is made of rubber, it has a certain degree of elasticity and flexibility. The limiting ring 2023 will gradually embed into the limiting groove 1043. When the rubber limiting ring 2023 is embedded into the limiting groove 1043, it will undergo a certain deformation and fit tightly against the inner wall of the limiting groove 1043, so that the upper mushroom buckle 202 can lock four The lower mushroom-shaped buckle 104 is locked by the mushroom head and then locked again by the limiting ring 2023, which further enhances the connection stability of the upper mushroom-shaped buckle 202 and the lower mushroom-shaped buckle 104 in the vertical direction and at various angles, greatly reducing the possibility of the buckle coming undone under complex external forces. When the buckle is under pressure, the presence of the buffer groove 105 allows the first buffer layer 103 and the second buffer layer 203 to undergo a certain degree of elastic deformation, absorbing and dispersing part of the impact force, and preventing the mushroom-shaped buckle from being damaged due to excessive instantaneous pressure.
