Description

Technical Field

[0001] This utility model relates to the field of webbing technology, specifically to an elastic adjustable webbing. Background Technology

[0002] Webbing is a strip-shaped material used for connecting, fixing, or decorating. It is usually made of fiber, plastic, or other synthetic materials. Due to its good elasticity, abrasion resistance, and adjustability, webbing has been widely used in many fields. In the clothing industry, webbing is often used to make belts, shoulder straps, and other parts, which are both beautiful and practical. In the field of sports equipment, elastic adjustable webbing can be used to connect and adjust equipment parts to meet the needs of different users. In addition, webbing is also widely used in packaging, fixing, and protection, such as for securing goods and protecting electrical wires.

[0003] According to patent document CN208472282U, an elastic webbing with adjustable tension is disclosed, comprising a webbing body integrally woven together. The webbing body includes a webbing main body and webbing sub-body integrally woven together by shuttle weaving. The webbing sub-body can freely appear in three spatial positions: upper, middle, and lower. The tension of the webbing main body can be freely adjusted by finely adjusting the tension of the webbing sub-body. This invention provides an elastic webbing with adjustable tension, employing a double-layer structure to create a double-layer elastic webbing. By adjusting the tension of the webbing sub-body, the tension of the entire elastic webbing can be freely adjusted.

[0004] While webbing has demonstrated unique advantages in many fields, there are still some areas for improvement. For example, adjusting the tightness of traditional webbing often requires manual operation, such as knotting or using additional fasteners. This is not only cumbersome, but also prone to loosening or damage after frequent adjustments or long-term use, affecting the performance of the webbing. In addition, the elasticity range of traditional webbing is limited, making it difficult to meet the needs of precise tightness adjustment in certain specific application scenarios.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 This utility model provides a technical solution: including a webbing take-up and release mechanism 1, a connecting block 3 fixedly connected to the top of the webbing take-up and release mechanism 1, and a webbing fixing mechanism 2 fixedly connected to the top of the connecting block 3.

[0023] Please see Figure 3The webbing take-up and take-down mechanism 1 includes a control frame 11, a take-up and take-down housing 12 fixedly connected to the rear side of the control frame 11, a control block 13 fixedly connected to the middle of the top of the inner wall of the control frame 11, a rotating rod 16 rotatably connected to the inner wall of the control block 13, a gear 14 fixedly connected to the middle of the outer wall of the rotating rod 16, a second gear 15 meshing with the top of the outer wall of the gear 14, and the outer wall of the second gear 15 rotatably connected to the middle of the top of the control frame 11. Both ends of the rotating rod 16 extend to the outer wall of the control block 13 and are fixedly connected with conical teeth 1. 7. The outer walls of the two conical teeth 17 are engaged with the second conical teeth 18. The inner walls of the two second conical teeth 18 are fixedly connected with rotating rollers 19. The rear ends of the two rotating rollers 19 extend to the inner wall of the take-up and release housing 12 and are respectively rotatably connected to the left and right sides of the rear side of the inner wall of the take-up and release housing 12. The two rotating rollers 19 are fixedly connected to the outer wall of one side of the inner wall of the take-up and release housing 12 with rotating rollers 110. The outer wall of the rotating rollers 110 is covered with webbing 111. One side of the two webbing 111 extends to the outer wall of the take-up and release housing 12.

[0024] When the length of the webbing 111 needs to be adjusted, the user can manually rotate the second gear 15. The second gear 15 meshes with the gear 14, causing the rotating rod 16 to rotate within the control block 13. At the same time, the conical teeth 17 on the rotating rod 16 mesh with the second conical teeth 18, driving the two rotating rollers 19 to rotate within the take-up and release housing 12, which in turn drives the rotating roller 110 to rotate, causing the webbing 111 to be wound or released on the rotating roller 110, thereby achieving the adjustment of the length of the webbing 111. The design of this webbing take-up and release mechanism 1 makes the adjustment of the webbing length more convenient and quick, improving work efficiency.

[0025] Please see Figure 3-4The webbing fixing mechanism 2 includes two base rods 21. An inverted L-shaped connecting rod 22 is fixedly connected to the top of each base rod 21. A guide plate 23 is fixedly connected to the top inner side of each inverted L-shaped connecting rod 22. A U-shaped connecting rod 213 is fixedly connected to the middle inner side of each inverted L-shaped connecting rod 22. Outer clamping plates 214 are fixedly connected to the left and right sides of each U-shaped connecting rod 213. Upright rods 24 are fixedly connected to the left and right sides of the top of the guide plate 23. A lead screw connecting plate 25 is fixedly connected to the top of each upright rod 24. A lead screw 26 is rotatably connected to the inner wall of the lead screw connecting plate 25. A handle 27 is fixedly connected to the top of the lead screw 26. The outer wall of the lead screw 26 is located at the bottom of the lead screw connecting plate 25. A transmission rod 28 is threadedly connected to one side of the part. The bottom of the transmission rod 28 extends to the bottom of the guide plate 23. The outer wall of the transmission rod 28 is slidably connected to the inner wall of the guide plate 23. Two rotating rods 29 are rotatably connected to the bottom of the transmission rod 28. A clamping plate 210 is rotatably connected to the side of the two rotating rods 29 away from the transmission rod 28. A shrinking plate 211 is fixedly connected to the top inner side of the two clamping plates 210. Two second rotating rods 212 are rotatably connected to the outer side of the two shrinking plates 211. The side of the two sets of second rotating rods 212 away from the second rotating rods 212 is rotatably connected to the top inner side of the outer clamping plate 214. A spring 215 is fixedly connected to the inner side of the two rotating rods 29.

[0026] When the elasticity of the webbing 111 needs to be adjusted, first place the two webbing 111 inside the outer clamping plate 214 and the clamping plate 210. Then turn the handle 27. The handle 27 drives the lead screw 26 to rotate within the lead screw connecting plate 25. When the lead screw 26 rotates, it drives the transmission rod 28 to move up and down through the threaded engagement. When the transmission rod 28 moves, it drives the two rotating rods 29 to rotate around the transmission rod 28 as the center. When the two rotating rods 29 rotate, they drive the two clamping plates 210 to move in opposite directions. When 210 moves, it drives two expansion plates 211 to rotate on the second rotating rod 212. When the two expansion plates 211 rotate, they clamp the webbing 111 between the outer clamping plate 214 and the clamping plate 210. Then, the webbing 111 is expanded or contracted by the webbing expansion mechanism 1, thereby stretching the webbing. The user can adjust the number of turns of the throttle 27 as needed to control the length of the stretched webbing 111, thereby achieving the purpose of adjusting the elasticity of the webbing 111.

[0027] Working principle: When it is necessary to adjust the length of the webbing 111, the user can manually rotate the second gear 15. The second gear 15 meshes with the gear 14, causing the rotating rod 16 to rotate within the control block 13. At the same time, the conical teeth 17 on the rotating rod 16 mesh with the second conical teeth 18, driving the two rotating rollers 19 to rotate within the take-up and release housing 12, which in turn drives the rotating roller 110 to rotate, causing the webbing 111 to be wound or released on the rotating roller 110, thereby achieving the adjustment of the length of the webbing 111.

[0028] When the elasticity of the webbing 111 needs to be adjusted, first place the two webbing 111 inside the outer clamping plate 214 and the clamping plate 210. Then turn the handle 27. The handle 27 drives the lead screw 26 to rotate in the lead screw connecting plate 25. When the lead screw 26 rotates, it drives the transmission rod 28 to move up and down through the threaded engagement. When the transmission rod 28 moves, it drives the two rotating rods 29 to rotate around the transmission rod 28. When the two rotating rods 29 rotate, they drive the two clamping plates 210 to move in opposite directions. When the two clamping plates 210 move, they drive the two expansion plates 211 to rotate on the second rotating rod 212. When the two expansion plates 211 rotate, they clamp the webbing 111 between the outer clamping plate 214 and the clamping plate 210. Then, the webbing 111 is expanded or contracted by the webbing expansion mechanism 1, thereby stretching the webbing. The user can adjust the number of turns of the handle 27 according to the needs, thereby controlling the length of the stretched webbing 111.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
