[0016] The present invention will be further described in detail below with reference to the accompanying drawings.
[0017] This embodiment discloses a securely connected hook and loop fastener, such as... Figures 1 to 5 As shown, this utility model has the effect of strong connection stability, including a first strip 1 and a second strip 2. The first strip 1 has a hook surface 3; the second strip 2 has a rough surface 4; a first magnet 5 and a second magnet 6 are respectively fixedly arranged on the hook surface 3 and the rough surface 4; the first magnet 5 and the second magnet 6 attract each other; side magnets 7 are arranged on the sides of the hook surface 3 and the rough surface 4; the side magnets 7 attract each other; a first reinforcing block 8 is connected to both ends of the first strip 1; a second reinforcing block 9 is connected to both ends of the second strip 2; the first reinforcing block 8 and the second reinforcing block 9 are detachably and fixedly connected.
[0018] By adopting the above technical solution: after the hook surface 3 and the rough surface 4 are connected, the first strip 1 and the second strip 2 are connected, and the first strip 1 and the second strip 2 can be respectively set on the two sides of the item to be bonded; after the first strip 1 and the second strip 2 are bonded to the rough surface 4 through the hook surface 3, the first magnet 5 and the second magnet 6 attract each other, and the side magnets 7 attract each other, thereby making the stability between the first strip 1 and the second strip 2 strong; the detachable and fixed connection between the first reinforcing block 8 and the second reinforcing block 9 further improves the connection stability between the first strip 1 and the second strip 2; the face-to-face sides of the first magnet 5 and the second magnet 6 attract each other, and the face-to-face sides of the side magnets 7 attract each other.
[0019] like Figure 1 As shown, the length of the side magnet 7 is the same as the length of the hook surface 3 and the rough surface 4; the first magnet 5 and the second magnet 6 are located at the middle of the hook surface 3 and the rough surface 4, respectively.
[0020] By adopting the above technical solution: the length of the side magnet 7 is consistent with the length of the hook surface 3 and the rough surface 4, and the first magnet 5 and the second magnet 6 are located in the middle of the hook surface 3 and the rough surface 4 respectively, so that the first strip 1 and the second strip 2 are firmly connected.
[0021] like Figure 2 As shown, the first reinforcing block 8 and the second reinforcing block 9 are both provided with connecting grooves 10; both ends of the first strip 1 and the second strip 2 are located in the connecting grooves 10 and are fixedly connected to the connecting grooves 10.
[0022] By adopting the above technical solution, the two ends of the first strip 1 and the second strip 2 are located in the connecting groove 10, thereby further improving the connection stability between the first reinforcing block 8 and the second reinforcing block 9.
[0023] like Figure 3 , Figure 4 As shown, the first reinforcing block 8 has a protrusion 11; the second reinforcing block 9 has a notch 12; the protrusion 11 is located inside the notch 12; the protrusion 11 has a through hole 13; the second reinforcing block 9 has a through hole 14 and a side groove 15; the through hole 13, the through hole 14, and the side groove 15 are provided with a snap-fit rod 16.
[0024] like Figure 3 , Figure 4 As shown, the snap-fit rod 16 has a washer 17; the snap-fit rod 16 has a spring 18 on its outer side; one end of the spring 18 is fixedly connected to the washer 17; the other end of the spring 18 is fixedly connected to one side of the notch 12.
[0025] By adopting the above technical solution: when connecting the first reinforcing block 8 and the second reinforcing block 9, the snap-fit rod 16 can be pulled outward first to compress the spring 18 on the snap-fit rod 16. Then, the protrusion 11 is placed in the notch 12. Then, the snap-fit rod 16 is released so that one end of the snap-fit rod 16 passes through the through hole 13 on the protrusion 11 and the other end is located in the side groove 15. When one end of the snap-fit rod 16 is located in the side groove 15, the spring 18 will rebound, so that one end of the snap-fit rod 16 is firmly set in the side groove 15, thereby making the connection between the first reinforcing block 8 and the second reinforcing block 9 stable. When the spring 18 rebounds, the washer 17 abuts against the protrusion 11, thereby making the snap-fit rod 16 set firmly.
[0026] In summary, this utility model has the following beneficial effects: after the hook surface 3 and the rough surface 4 are connected, the first magnet 5 and the second magnet 6 can attract each other, and the side magnets 7 can attract each other, thereby making the stability between the first strip 1 and the second strip 2 strong; the protrusion 11 on the first reinforcing block 8 is located in the notch 12 opened on the second reinforcing block 9, and the snap-fit rod 16 passes through the through hole 13 on the protrusion 11, and one end of the snap-fit rod 16 is located in the side groove 15, thereby making the connection between the first reinforcing block 8 and the second reinforcing block 9 more stable and further improving the stability of the first strip 1 and the second strip 2.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
