Description

Technical Field

[0001] This utility model relates to the field of hook and loop fasteners, and in particular to a splicable hook and loop fastener. Background Technology

[0002] Hook and loop fasteners are a common connecting accessory used in bags and clothing. They have two sides: a male side with fine, soft fibers and a female side with elastic, hook-and-loop fibers. When the two sides are interlocked, under a certain lateral force, the elastic hooks are straightened, detach from the loops, and open, then return to their original shape. They can be opened and closed repeatedly. For example, patent document CN222532835U, entitled "A Hook and Loop Fastener with a Splicable Structure," discloses a splicable hook and loop fastener. By setting a concave surface in the first component, the first hook and loop are interlocked with the second component, resulting in a tight surface-to-surface fit between the first and second components.

[0003] However, the above-mentioned technical solutions lack structures to prevent or limit detachment, making them prone to falling off when hook and loop fasteners are connected. Therefore, it is necessary to develop a newer technical design that is simple in structure and not easily detached, thereby solving the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a splicable hook and loop fastener to solve the problems in the background art where hook and loop fasteners are prone to falling off when connected.

[0005] This utility model provides the following technical solution: a splicable hook and loop fastener, comprising a base unit, wherein the base unit is provided with a hook surface assembly, a rough surface assembly and a connecting assembly, the hook surface assembly is disposed on the front side of the base unit, the rough surface assembly is disposed on the back side of the base unit, and the connecting assembly is disposed around the base unit. The connecting assembly includes a sub-connector and a female connector, the sub-connector and the female connector are matched with each other, and two sets of each sub-connector and female connector are provided. The two sets of sub-connectors are perpendicularly disposed on the edge of the base unit, and the two sets of female connectors are perpendicularly disposed on the edge of the base unit relative to the sub-connectors.

Two sets of each type of connector are provided, with the two sets of sub-connectors perpendicularly positioned along the edge of the base unit, and the two sets of female connectors perpendicularly positioned relative to the sub-connectors along the edge of the base unit. This design allows users to splice multiple hook and loop fasteners together as needed. When one hook and loop fastener is damaged, only the damaged fastener needs to be replaced, eliminating the need to replace the entire unit, effectively reducing costs.

[0015] 2. The splicable hook and loop fastener of this utility model includes a connecting groove for connecting with a sub-connector, and a first limiting part is provided in the connecting groove to prevent the sub-connector from falling off.

For the same part in the embodiments of this application, the reference numerals may only be used to mark one part or component as an example. It should be understood that the reference numerals are also applicable to other identical parts or components.

[0035] Furthermore, in this application, the technical features described in an open-ended manner include both closed technical solutions composed of the listed features and open technical solutions that include the listed features.

[0036] To further understand the utility model content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0037] like Figure 1-6 As shown, the splicable hook and loop fastener includes a base unit 1. The base unit 1 has a hook surface assembly 2, a rough surface assembly 3, and a connecting assembly 4. The hook surface assembly 2 is located on the front of the base unit 1, the rough surface assembly 3 is located on the back of the base unit 1, and the connecting assembly 4 is located around the base unit 1. The connecting assembly 4 includes sub-connectors 41 and female connectors 42, which are mutually matched. Two sets of each sub-connector 41 and female connector 42 are provided. The two sets of sub-connectors 41 are perpendicularly arranged at the edge of the base unit 1, and the two sets of female connectors 42 are perpendicularly arranged opposite the sub-connectors 41 at the edge of the base unit 1. In this embodiment, the connecting assembly allows the user to splice multiple hook and loop fasteners according to usage. When one hook and loop fastener is damaged, only the damaged fastener needs to be replaced, without replacing the entire unit, effectively reducing costs. Of course, this is not a limitation; other straight lines can be used to splice the hook and loop fasteners together.

[0038] Specifically, the female connector 42 includes a connecting groove 421 for connecting with the male connector 41, and a first limiting part 422 is provided in the connecting groove 421 to prevent the male connector 41 from falling off. In this embodiment, by setting the first limiting part, when the male connector and the female connector are connected, the male connector can be prevented from detaching from the female connector. Of course, it is not limited to this, and other methods to prevent the male connector from detaching from the female connector can be used.

[0039] Specifically, the sub-connector 41 includes a connecting block 411 that matches the connecting groove 421. A second limiting part 412 is provided on the connecting block 411. The second limiting part 412 and the connecting block 411 are fixedly connected or integrally formed. The first limiting part 422 and the second limiting part 412 match each other. In this embodiment, when the first limiting part and the second limiting part engage with each other, the connecting block can be effectively prevented from disengaging from the connecting groove. Of course, this is not limited to this; other methods can be used to prevent the connecting block from disengaging from the connecting groove.

[0040] Specifically, the connecting block 411 is further provided with an elastic pressing part 413. The elastic pressing part 413 and the second limiting part 412 are fixedly connected or integrally formed. Pressing the elastic pressing part 413 causes the second limiting part 412 to disengage from the first limiting part 422, thereby causing the connecting block 411 to disengage from the connecting groove 421. In this embodiment, the pressing part can cause the second limiting part to disengage from the first limiting part, thereby causing the connecting block to disengage from the connecting groove; making the disassembly of the hook and loop fasteners simple and quick. Of course, it is not limited to this; other simple methods to disengage the second limiting part from the first limiting part are also possible.

[0041] Specifically, the connecting block 411, the second limiting part 412, and the elastic pressing part 413 are made of plastic. In this embodiment, the plastic material reduces production costs while also providing better elasticity to the elastic pressing part. Of course, the choice of material is not limited to this; any other material that reduces production costs while also providing better elasticity to the elastic pressing part can be used.

[0042] Specifically, the baseband unit 1, hook surface assembly 2, and rough surface assembly 3 are formed by hot pressing. In this embodiment, hot pressing makes the overall structure of the hook and loop fastener more stable. Of course, it is not limited to this; other methods that enhance the overall structure can be used.

[0043] Specifically, a nylon strap 5 is provided around the baseband unit 1, and the baseband unit 1 and the nylon strap 5 are fixedly connected. The connecting component 4 and the nylon strap 5 are connected by heat fusion sealing. In this embodiment, the connecting component and the nylon strap are connected by heat fusion sealing. This connection method makes the connection between the connecting component, the nylon strap, and the baseband unit more stable. Of course, it is not limited to this; other methods can be used to make the connection between the connecting component, the nylon strap, and the baseband unit more stable.

[0044] Working principle: When using, when it is necessary to splice the hook and loop fasteners together, insert the connecting block into the connecting groove. The first limiting part and the second limiting part match and engage with each other, which effectively prevents the connecting block from detaching from the connecting groove. When it is necessary to disassemble the hook and loop fasteners, press the elastic pressing part, which will drive the second limiting part to disengage from the first limiting part, thereby driving the connecting block to disassemble from the connecting groove, thus completing the disassembly of the hook and loop fasteners.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
