Description

TECHNICAL FIELD

[0001] The application relates to the technical field of hook-and-loop fasteners, and in particular to a double-hook hook-and-loop fastener with reliable fixation. BACKGROUND

[0002] A hook-and-loop fastener is a common connecting auxiliary material, which is usually composed of a hook surface and a loop surface. The working principle is that the hook-shaped fabric of the hook surface is attached to the loop-shaped fabric of the loop surface, thereby generating natural adhesion to achieve rapid connection. However, the hooks of the traditional hook-and-loop fastener are mostly single-layer, and after long-term connection of the claw hooks and the loop, the connection is prone to become unstable due to repeated separation and adhesion, which causes the two to easily separate.

[0003] At present, the Chinese utility model patent application with the publication number CN 220631280U and the publication date of March 22, 2024 provides a stretchable hook-and-loop fastener, which comprises a stretchable band, the upper end of the stretchable band is fixedly connected with a fixed block, the inner wall of the fixed block is provided with a sliding groove, two sliding grooves are symmetrically arranged, the bottom wall of the sliding groove is fixedly connected with a spring, and the sliding groove is slidably connected with a sliding block. The stretchable hook-and-loop fastener is characterized in that the threaded rod is rotated in the threaded hole by rotating the rotating disc, the threaded rod is rotated downward, the bottom of the threaded rod presses the upper end of the fixed plate to make the fixed plate move downward, the sliding blocks at both ends of the fixed plate press the springs in the sliding grooves to make the springs deform under stress and make the sliding blocks slide downward in the sliding grooves, thereby driving the fixed columns at the lower end of the fixed plate to make the pressing plate move downward, the pressing plate presses the stretchable band in the fixed block, and the stretchable band is fixed firmly to improve the fixing effect.

[0004] In the related art, the double-hook hook-and-loop fastener with reliable fixation is mainly fixed by the fixed block pressing the stretchable band, and the remaining band of the stretchable band is fixed by the hook-and-loop fastener. However, the structure of the hook-and-loop fastener is relatively simple, the hooks of the hook-and-loop fastener are single-layer, and after long-term connection of the claw hooks and the loop, the connection is prone to become unstable due to repeated separation and adhesion, which causes the two to easily separate. In the process of frequent use, the hook-shaped structure of the hook surface is prone to deformation or damage, such as straightening of the bent hook, insufficient bending degree, etc., thereby affecting the service life of the hook-and-loop fastener.

DETAILED DESCRIPTION

[0021] Based on this, in order to improve the technical problem that the structure of the hook-and-loop tape is relatively simple, the claw hook and the hanging wool are repeatedly separated and bonded, and the connection is easy to become unfirm, thereby affecting the service life of the hook-and-loop tape, the embodiment of the application provides the following scheme.

[0022] Please refer to Figures 1 to 3 , the embodiment of the application provides a fixed reliable double-shot hook hook-and-loop tape, the fixed reliable double-shot hook 12 hook-and-loop tape, which comprises a first connecting tape 1, a second connecting tape 2, a first rubber support layer 11, a second rubber support layer 22, a connecting cloth 21, hanging wool 23 and a double-shot hook 12, the first rubber support layer 11 is arranged on the first connecting tape 1, the second rubber support layer 22 is arranged on the second connecting tape 2, the connecting cloth 21 is arranged on the side of the second rubber support layer 22 away from the second connecting tape 2, the hanging wool 23 is arranged on the side of the connecting cloth 21 away from the second rubber support layer 22, and the double-shot hook 12 is arranged on the end of the first rubber support layer 11 away from the first connecting tape 1.

[0023] In some embodiments, please refer to Figures 1 to 3 , the double-shot hook 12 comprises a connecting column 121, an upper hook claw 122 and a lower hook claw 123, the connecting column 121 is arranged on the end of the first rubber support layer 11 away from the first connecting tape 1, the upper hook claw 122 is arranged on the connecting column 121, the lower hook claw 123 is arranged on the connecting column 121, the first rubber support layer 11 and the second rubber support layer 22 are semicircular, the first rubber support layer 11 and the second rubber support layer 22 are engaged and connected, and the length of the lower hook claw 123 is greater than the length of the upper hook claw 122.

[0024] In this way, the combination of the upper hook claw 122 and the lower hook claw 123 can provide stronger gripping force, and the length of the lower hook claw 123 is greater than that of the upper hook claw 122, which means that the lower hook claw 123 can be embedded deeper into the hook 23, providing a stronger anchoring effect, while the upper hook claw 122 can provide additional gripping force to ensure a more secure connection. At the same time, the first rubber support layer 11 and the second rubber support layer 22 are semi-circular and connected with each other, and this structure is similar to the engagement of gears, which can effectively disperse and balance external forces, and also increase the contact area between the double hook 12 and the hook 23. The rubber material itself has good elasticity and flexibility, and the design of the semi-circular rubber support layer makes the hook-and-loop fastener better adapt to different bending and twisting forces during use, and it can quickly recover to its original state after being subjected to external forces, maintaining good connection performance. The design of the semi-circular rubber support layer and the double hook claw in engagement connection makes the hook-and-loop fastener better disperse and absorb external forces during use, reducing local stress concentration and thus reducing the risk of damage caused by excessive pulling or frequent use. This design of the hook-and-loop fastener makes it more convenient and faster to use. Users only need to press lightly, and the double hook claw can be tightly combined with the hook 23 to achieve quick fixing; when disassembling, it only needs to be pulled apart lightly, which is simple and easy to operate. Due to its strong connection ability and durability, this hook-and-loop fastener can provide more reliable fixing effect for users and reduce the safety hazards caused by loose hook-and-loop fasteners.

[0025] In some embodiments, please refer to Figures 1 to 2 , the first connecting band 1 is provided with a first reinforcing layer 13 at one end away from the first rubber support layer 11, the second connecting band 2 is provided with a second reinforcing layer 25 at one end away from the second rubber support layer 22, the second reinforcing layer 25 is provided with a waterproof film 24 at one end away from the second connecting band 2, and the outer side edges of the first connecting band 1 and the second connecting band 2 are respectively fixedly connected with a shielding part 3, and the shielding part 3 is provided with a connecting band 4 at one side away from the first connecting band 1 and the second connecting band 2.

[0026] Thus, the design of the first reinforcing layer 13 and the second reinforcing layer 25 increases the wear resistance of the hook-and-loop fastener. The reinforcing layers can significantly enhance the anti-pulling ability of the end of the hook-and-loop fastener, preventing deformation or damage of the end of the connecting band 4 due to excessive pulling during use. At the same time, the waterproof film 24 is provided outside the second reinforcing layer 25, reducing the risk of the hanging wool 23 being wetted and thus reducing the adhesion, thereby reducing the service life of the hook-and-loop fastener. The waterproof film 24 can effectively prevent moisture from penetrating into the hook-and-loop fastener, thereby protecting the internal structure from a humid environment. At the same time, the design of the shielding part 3 reduces accidental detachment due to external forces during use. The shielding part 3 is fixed to the outer edge of the first connecting band 1 and the second connecting band 2, which can effectively protect the edge of the connecting band 4, preventing edge wear, tearing or curling. This design not only prolongs the service life of the hook-and-loop fastener, but also maintains the neatness and beauty of its appearance. The shielding part 3 not only has a protective function, but also has a decorative effect. By designing shielding parts 3 of different colors, patterns or materials, the overall appearance of the hook-and-loop fastener can be improved, making it more suitable for use in clothing, luggage and other products that have high requirements for appearance. The connecting band 4 facilitates the separation of the hanging wool 23 and the double-shot hook 12. This design of the double-shot hook 12 hook-and-loop fastener improves its strength, durability and waterproof performance by adding reinforcing layers, waterproof films 24 and shielding parts 3, and enhances its appearance and use safety, making it better meet the diverse needs of users.

[0027] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
