Description

Technical Field

[0001] The utility model relates to the technical field of hook and loop fasteners, in particular to a back-to-back injection hook and loop fastener. Background Art

[0002] Velcro, also known as magic tape, is a common and practical connecting auxiliary material. Velcro usually consists of two parts, one side is a soft fibrous hair surface, and the other side is a hook surface with tiny hooks. When the hair surface and the hook surface contact each other, they will stick together tightly to achieve the function of fixing and connecting. It is easy to use and can be quickly adhered and separated without complicated operations. Secondly, it has strong adaptability and can be applied to various materials and surfaces. In addition, Velcro has a certain durability and can still maintain a good adhesion effect after repeated use. Among them, some Velcro adopts the back-to-back injection form, which can increase the thickness and strength of the Velcro. Compared with the traditional single-layer Velcro, the back-to-back injection shape makes the Velcro thicker, so it has better stability and durability when subjected to tension and pressure.

[0003] Existing back-to-back injected Velcro is usually made of materials such as nylon, which has good durability and strength and excellent bonding strength. Because the hook surface and the hair surface on both sides are closely combined, the contact area during adhesion is increased, which significantly improves the adhesion force. It can firmly connect various objects and is more stable. It can withstand frequent use and large pulling force and is not easy to deform or damage.

[0004] However, the existing back-to-back injected Velcro usually has strong adhesion, which ensures the stability of its connection to a certain extent, but at the same time it is also difficult to remove it conveniently. Due to its strong adhesion, it is necessary to exert a large force when separating it, which makes the operation more laborious. In addition, there is a lack of force-bearing tape during the removal process, which means that when the user tries to separate the Velcro, there is no structure to apply force, resulting in a lack of an effective fulcrum for the removal action, further increasing the difficulty and inconvenience of the operation. For this reason, a back-to-back injected Velcro is proposed to solve the above problems. Utility Model Content

[0027] Reference Figure 1-Figure 3 The utility model provides an embodiment: back-to-back injection Velcro, including Velcro 1, a hook surface 2 is fixedly connected to the top of the Velcro 1, a suede surface 3 is fixedly connected to the top of the Velcro 1, a connecting disc 8 is fixedly connected inside the Velcro 1, a connecting belt 6 is arranged on the outer wall of the Velcro 1, an anti-slip disc 7 is fixedly connected inside the connecting belt 6, a fixed disk 5 is arranged on the top of the Velcro 1, a fixing column 9 is fixedly connected to the outer wall of the fixing disk 5, the outer wall of the fixing column 9 is slidably connected to the inside of the Velcro 1, the outer wall of the fixing column 9 is slidably connected to the inside of the connecting belt 6, a fixing component is arranged inside the fixing column 9, and the fixing component acts to fix the fixing column 9.

[0028] Specifically, when faced with a situation where contact adhesion is required, the connecting tape 6 can be cleverly used to tear it off more conveniently without using excessive force or using sharp tools to forcibly separate the Velcro 1, effectively avoiding possible damage to the surface of the object connected thereto, and being able to comprehensively protect the surface of the object connected thereto from the risk of scratches or breakage. At the same time, in order to further optimize the performance, an anti-slip disc 7 is deliberately added to the position where the inside of the Velcro 1 and the connecting tape 6 contact each other, which can significantly increase the friction, thereby making the connection more stable and reliable. In addition, since the Velcro 1 and the connecting tape 6 are both sewn products, this feature further enhances their stability. The sewing process makes the connection between the various components tighter and firmer, making it less likely to be damaged during use, greatly extending the service life, and improving the overall reliability and durability.

[0029] Reference Figure 3 The fixing assembly includes a block 10 , and the outer wall of the block 10 is slidably connected to the inside of the fixing column 9 .

[0030] Specifically, the device is fixed by the block 10 inside the fixing column 9 to prevent it from falling off by itself. This fixing method can ensure that the device remains stable during use and avoid the device from loosening or falling off due to unexpected circumstances, thereby improving the reliability and safety of the device.

[0031] Reference Figure 1 and Figure 3 The fixed column 9 is slidably connected with a pressing column 14 inside, and the outer wall of the pressing column 14 is fixedly connected with a connecting rod 4. The bottom of the pressing column 14 is fixedly connected with a sliding column 13. The outer wall of the sliding column 13 is sleeved with a spring 2 15. The top of the spring 2 15 is fixedly connected to the bottom of the pressing column 14. The bottom of the spring 2 15 is fixedly connected with a fixed disc 2 16. The outer wall of the fixed disc 2 16 is fixedly connected to the inside of the fixed column 9. The outer wall of the sliding column 13 is slidably connected to the inside of the fixed disc 2 16. The bottom of the sliding column 13 is fixedly connected with a conical slider 17. The outer wall of the conical slider 17 is slidably connected to a roller 19. The outer wall of the roller 19 is rotatably connected to a connecting column 18. The outer wall of the connecting column 18 is sleeved with a spring 11. One end of the spring 11 is fixedly connected to the outer wall of the block 10, and the other end of the spring 11 is fixedly connected to a fixed disc 12. The outer wall of the fixed disc 12 is fixedly connected to the inside of the fixed column 9, and the outer wall of the connecting column 18 is slidably connected to the inside of the fixed disc 12.

[0032] Specifically, the connecting rod 4 is pressed. Under this operation, the pressing column 14 can be effectively driven to descend by virtue of the powerful conduction effect of the connecting rod 4. Then, the sliding column 13 is driven to descend by the pressing column 14, and the conical slider 17 is driven to descend together. At the same time, during the pressing process, the pressing column 14 will strongly compress the spring 2 15. Then, due to the continuous descent of the conical slider 17, the rebound characteristics of the spring 1 11 can effectively drive the card block 10 to slide smoothly into the interior of the fixed column 9, so that the fixed column 9 can be easily removed from the Velcro. 1 is taken out from the inside, which is simple and efficient, and provides great convenience for subsequent maintenance and cleaning work. When the connecting belt 6 is dirty or damaged, the advantage of being able to be easily replaced is particularly prominent. The connecting belt 6 can be treated specifically alone, and there is no need to carry out comprehensive cleaning or maintenance operations on the entire item, which effectively extends the service life of the item. Because in actual use, the worn or aged connecting belt 6 can be replaced alone, so there is no need to discard the entire item helplessly just because of the problem caused by the connecting belt 6.

[0033] Working principle: when the Velcro 1 is separated, align the connecting belt 6 with the anti-skid disc 7 and the connecting disc 8 fixed inside the Velcro 1, then press the connecting rod 4, and drive the fixedly connected pressing column 14 to move through the connecting rod 4, and then drive the fixedly connected sliding column 13 to descend through the pressing column 14, and at the same time, compress the fixedly connected spring 2 15 through the pressing column 14, and then drive the fixedly connected conical slider 17 to descend through the sliding column 13, and then drive the fixedly connected block 10 to move through the rebound of the spring 11, and at the same time, drive the fixedly connected connecting column 18 to move through the block 10, and then Then, the connecting column 18 drives the rotating connected roller 19 to slide on the outer wall of the conical slider 17 to which it is slidably connected. Then, the fixing column 9 can be put into the Velcro 1 and the connecting belt 6 to connect them. Then, the connecting rod 4 is loosened, and the pressing column 14 is driven to return to its original position by the rebound of the spring 2 15. Then, the conical slider 17 is driven to return to its original position by the pressing column 14, thereby pushing the roller 19 to slide, and pushing the connecting column 18 to move. Then, the fixedly connected block 10 is driven to move by the connecting column 18, and at the same time, the spring 11 is driven to stretch for subsequent use, thereby fixing it, and the Velcro 1 can be easily removed.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
