[0002] Velcro, also known as Magic Tape, is a practical quick-connect material made of synthetic materials such as nylon or polyester. It consists of two parts: the hook side and the fleece side. The hook side has tiny hooks, while the fleece side is covered with countless tiny loops. When the two parts are pressed together, the hooks will tightly hook the loops, thus achieving a strong bond. Velcro is widely used in various daily necessities, clothing, backpacks, shoes, car interiors and many other fields due to its convenient connection and separation method.

[0003] The Velcro on the market currently usually has a fixed length. This design may not meet the length requirements of different individuals when used. Due to the differences in body shape and posture of each person, the length of the Velcro suitable for them may also be different. This fixed length design may cause some problems, such as insufficient length, which cannot provide a sufficient fixing effect; or too long length, which makes the excess part cumbersome and unsightly. Therefore, a Velcro with adjustable length is proposed to solve the above problems. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a length-adjustable Velcro, comprising a waist belt 1, wherein two sliding rods 14 are fixedly connected inside the waist belt 1, and sliding rings 13 are slidably connected to the outer peripheries of the two sliding rods 14, and an adjusting belt 8 is fixedly connected between the two sliding rings 13, and an adhesive component is fixedly connected to one end of the adjusting belt 8. When the Velcro needs to be lengthened, the hook surface belt 7 is pulled outward, thereby driving the adjusting belt 8 to slide in the waist belt 1, and the two sliding rings 13 on the adjusting belt 8 will also slide on the corresponding sliding rods 14, thereby ensuring that the movement trajectory and shape of the adjusting belt 8 will not deviate, the adjusting belt 8 is slidably connected inside the waist belt 1, and a connecting block 4 is fixedly connected to the top of the adjusting belt 8, and the connecting block 4 is slidably connected to the middle part of the waist belt 1. When it needs to be shortened, the connecting block 4 is slid inwardly, thereby driving the adjusting belt 8 to slide in the waist belt 1, and the two sliding rings 13 on the adjusting belt 8 will also slide on the corresponding sliding rods 14, thereby ensuring stability, thereby realizing the adjustment of the length of the Velcro, so that the Velcro can be suitable for more people, greatly reducing the use cost and improving the cost performance.

[0031] Reference Figure 1 and Figure 3The utility model provides an embodiment: a locking box 9 is fixedly connected to one side of the waist belt 1, a connecting column 15 is slidably connected to the middle of the locking box 9, a button 6 is fixedly connected to the top of the connecting column 15, a locking block 19 is fixedly connected to the bottom of the connecting column 15, two springs 17 are fixedly connected to the inside of the locking box 9, one end of the two springs 17 is fixedly connected to the block 18, the block 18 is slidably connected to the inside of the locking box 9, when the required length is adjusted, the button 6 is pressed inward, thereby driving the connecting column 15 and the locking block 19 downward, the two springs on the locking block 19 are fixedly connected to the inside of the locking box 9, and the two springs 17 are fixedly connected to the inside of the locking box 9. The groove 16 will squeeze the two blocks 18 outward, causing the two blocks 18 to squeeze the two springs 17 until the locking block 19 falls completely. The two blocks 18 will then be pushed back to their original positions by the elastic force of the two springs 17, thereby locking the locking blocks 19. The locking blocks 19 will also lock the adjustment belt 8 below. When the length needs to be adjusted, it is only necessary to rotate the button 6 to drive the locking blocks 19 to disengage from the lock of the two blocks 18 to contact the locked state, thereby realizing the locking function of the Velcro length, improving the stability of the device, and enhancing the fixing effect of the device.

[0032] Reference Figure 1 and Figure 3 The utility model provides an embodiment: an adhesive component includes a hook belt 7, which is fixedly connected to one end of an adjusting belt 8, a suede 2 is fixedly connected to the top of the belt 1, and a tension belt 3 is fixedly connected to one side of a connecting block 4. The tension belt 3 is convenient for users to pull the connecting block 4, and a wear-resistant layer 11 is fixedly connected to the top of the belt 1. The wear-resistant layer 11 is made of a more wear-resistant material, which prolongs the service life of the device. The suede 2 is fixedly connected to the middle of the wear-resistant layer 11, and a skin-friendly layer 10 is fixedly connected to the top of the belt 1. The skin-friendly layer 10 is fixedly connected to one side of a locking box 9. The skin-friendly layer 10 is made of a more gentle material. A hanging rope 12 is fixedly connected to one end of the belt 1. The hanging rope 12 is convenient for storing the device. The four corners of the top of the locking box 9 are fixedly connected to anti-scratch corners 5. The anti-scratch corners 5 can prevent sharp edges from scratching users, and grooves 16 are provided on both sides of the locking block 19.

[0033] Working principle: when the Velcro needs to be lengthened, pull the hook belt 7 outwards, thereby driving the adjusting belt 8 to slide in the waist belt 1, and the two sliding rings 13 on the adjusting belt 8 will also slide on the corresponding sliding rod 14, thereby ensuring that the movement trajectory and shape of the adjusting belt 8 will not deviate. When it needs to be shortened, slide the connecting block 4 inwards, thereby driving the adjusting belt 8 to slide in the waist belt 1, and the two sliding rings 13 on the adjusting belt 8 will also slide on the corresponding sliding rod 14, ensuring stability, thereby achieving adjustment of the length of the Velcro, making the Velcro suitable for more people, greatly reducing the cost of use, and improving the cost performance.

[0034] When the required length is adjusted, the button 6 is pressed inward, thereby driving the connecting column 15 and the locking block 19 downward, and the two grooves 16 on the locking block 19 will squeeze the two blocks 18 outward, causing the two blocks 18 to squeeze the two springs 17 until the locking block 19 falls completely. The two blocks 18 will then be pushed back to their original positions by the elastic force of the two springs 17, thereby locking the locking block 19, and the locking block 19 will also lock the adjustment belt 8 below. When the length needs to be adjusted, it is only necessary to rotate the button 6 to drive the locking block 19 to disengage the locking of the two blocks 18 to contact the locked state, thereby realizing the locking function of the Velcro length, improving the stability of the device, and enhancing the fixing effect of the device.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
