Description

A cable tensioning device Technical Field

[0001] This utility model relates to the field of cable tensioning technology, specifically to a cable tensioning device. Background Technology

[0002] Cables are typically rope-like structures made of several or groups of conductors twisted together. Each group of conductors is insulated from each other and is often twisted around a central core. The entire structure is covered with a highly insulating outer layer. CN219801685 U discloses a cable tensioning device, which includes an operating plate. A motor is fixedly mounted on the bottom surface of the operating plate, and a tensioning mechanism and a tensioning wheel mechanism are located on the front surface of the operating plate. This cable tensioning device, through the cooperation of a fixed sleeve, screw, moving plate, and U-shaped frame, drives a ring-shaped clamping plate to move linearly in the back-and-forth direction when the rotating plate rotates. This adjusts the distance between the ring-shaped clamping plate and the fixed circular plate, ensuring that the ring-shaped clamping plate and the fixed circular plate fit against the outer side of the cable. This prevents the cable from moving and rubbing against the surface of the fixed column during tension adjustment, thus avoiding cable wear and affecting cable performance. If impurities enter the square groove, the bolts are unscrewed to disassemble the rotating plate, and the inside of the square groove is cleaned to prevent impurities from affecting the movement of the moving plate.

[0003] In the above scheme, when the tensioning mechanism slides up and down, the cables on both sides of the tensioning mechanism and the tensioning wheel mechanism will contract or relax simultaneously. However, in actual use, the cables on both sides of the device do not need to be tightened or loosened at the same time, so the device is not practical. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a cable tensioning device that has the advantage of tensioning one side of the cable and avoids the problem of both sides of the cable sliding simultaneously during tensioning.

[0005] To achieve the purpose of tensioning one side of the cable, this utility model provides the following technical solution:

[0006] A cable tensioning device includes a main board, with fixing components mounted on both side walls of the main board for fixing cables, and winding components mounted on the side walls of the main board for winding cables. The device also includes:

[0007] The winding assembly includes a first threaded post, a second threaded post, a third threaded post, and a fourth threaded post. The first threaded post, the second threaded post, the third threaded post, and the fourth threaded post are all rotatably mounted on the inner wall of the main board. The side walls of the first threaded post, the second threaded post, the third threaded post, and the fourth threaded post are threadedly connected to connecting plates. The side walls of the connecting plates are respectively rotatably connected to first rotating wheels, second rotating wheels, third rotating wheels, and fourth rotating wheels. The first threaded post, the second threaded post, the third threaded post, and the fourth threaded post correspond one-to-one with the first rotating wheel, the second rotating wheel, the third rotating wheel, and the fourth rotating wheel.

[0008] According to some embodiments, the fixing component includes a fifth rotating wheel, which is rotatably mounted on both sides of the motherboard. A mounting plate is fixedly connected to the side wall of the motherboard, and a threaded bolt is threadedly connected to the top of the mounting plate. A fixing block is rotatably connected to the end of the threaded bolt, and the side wall of the fixing block is set to be inclined.

[0009] According to some embodiments, the first threaded post, the second threaded post, the third threaded post and the fourth threaded post are all threaded with nuts on their sidewalls, and the nuts are used to fix the first threaded post, the second threaded post, the third threaded post and the fourth threaded post.

[0010] According to some embodiments, a limiting post is fixedly connected to the top of the fixing block, the limiting post penetrates the mounting plate, and grooves are provided on the side walls of the first, second, third, fourth and fifth rotating wheels. Cables are slidably connected to the inner cavity of the grooves, and the first, second, third, fourth and fifth rotating wheels are all on the same plane.

[0011] Beneficial effects

[0012] This utility model provides a cable tensioning device, which has the following beneficial effects:

[0013] This cable tensioning device is designed to tighten the cables on the left side of the motherboard. The cables on the right side of the motherboard are secured using a fixing component. Rotating the third threaded column causes the third rotating wheel to slide upwards, loosening the cable between the second and fourth rotating wheels. Rotating the second threaded column then causes the second rotating wheel to slide upwards, tightening the cables on the left side of the motherboard. The upward sliding of the cable between the second and fourth rotating wheels does not affect the tension of the cables on the right side of the motherboard, thus completing the tightening of the cables on the left side of the motherboard and the overall tightening of one side of the motherboard.

[0018] 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.

[0019] Referring to Figures 1-3, a cable tensioning device includes a main board 1, with fixing components 2 installed on both side walls of the main board 1 for fixing cables, and winding components 3 installed on the side walls of the main board 1 for winding cables. The device also includes:

[0020] The winding assembly 3 includes a first threaded post 301, a second threaded post 302, a third threaded post 303, and a fourth threaded post 304. The first threaded post 301, the second threaded post 302, the third threaded post 303, and the fourth threaded post 304 are all rotatably mounted on the inner wall of the main board 1. The side walls of the first threaded post 301, the second threaded post 302, the third threaded post 303, and the fourth threaded post 304 are all threadedly connected to a connecting plate 305. The side walls of the connecting plate 305 are respectively rotatably connected to a first rotating wheel 306, a second rotating wheel 307, a third rotating wheel 308, and a fourth rotating wheel 309.

[0021] The first threaded post 301, the second threaded post 302, the third threaded post 303 and the fourth threaded post 304 correspond one-to-one with the first rotating wheel 306, the second rotating wheel 307, the third rotating wheel 308 and the fourth rotating wheel 309;

[0022] It should be noted that: Cable 402 is sequentially routed around the side walls of the first rotating wheel 306, the second rotating wheel 307, the third rotating wheel 308, and the fourth rotating wheel 309. The first threaded post 301, the second threaded post 302, the third threaded post 303, and the fourth threaded post 304 are rotated respectively to adjust the height of the first rotating wheel 306, the second rotating wheel 307, the third rotating wheel 308, and the fourth rotating wheel 309, thus clamping cable 402. For example, if it is necessary to tighten cable 402 on the left side of motherboard 1, the fixing component 2 can be used to clamp cable 402 on the right side of motherboard 1. The cable 402 between the second and fourth rotating wheels is loosened by rotating the third threaded post 303 and then rotating the third threaded post 303 to make the corresponding connecting plate 305 slide the third rotating wheel 308 upward. Then, the second threaded post 302 is rotated to make the second rotating wheel 307 slide upward, thereby tightening the cable 402 on the left side of the motherboard 1. The upward sliding of the cable 402 between the second rotating wheel 307 and the fourth rotating wheel 309 will not affect the tightness of the cable 402 on the right side of the motherboard 1, thus completing the tightening of the cable 402 on the left side of the motherboard 1.

[0023] Referring to Figures 1-3, the fixing component 2 includes a fifth rotating wheel 201, which is rotatably mounted on both side walls of the main board 1. A mounting plate 202 is fixedly connected to the side wall of the main board 1.

[0024] The top of the mounting plate 202 is threadedly connected to a threaded bolt 203, and the end of the threaded bolt 203 is rotatably connected to a fixing block 204, and the side wall of the fixing block 204 is set to be inclined.

[0025] It should be noted that rotating the threaded bolt 203 on the top of the mounting plate 202 causes the threaded bolt 203 to drive the fixing block 204 closer to the fifth rotating wheel 201, thereby fixing the cable 402 on the side wall of the fifth rotating wheel 201.

[0026] Referring to Figures 1-3, the first threaded post 301, the second threaded post 302, the third threaded post 303 and the fourth threaded post 304 are all threaded with nuts 4 on their sidewalls. The nuts 4 are used to fix the first threaded post 301, the second threaded post 302, the third threaded post 303 and the fourth threaded post 304.

[0027] The top of the fixing block 204 is fixedly connected to the limiting post 401, which penetrates the mounting plate 202.

[0028] The first rotating wheel 306, the second rotating wheel 307, the third rotating wheel 308, the fourth rotating wheel 309 and the fifth rotating wheel 201 all have grooves on their side walls, and cables 402 are slidably connected to the inner cavity of the grooves;

[0029] The first rotating wheel 306, the second rotating wheel 307, the third rotating wheel 308, the fourth rotating wheel 309, and the fifth rotating wheel 201 are all on the same plane;

[0030] It should be noted that: Nut 4 is used to fix the first threaded post 301, the second threaded post 302, the third threaded post 303 and the fourth threaded post 304 to fix the position of the cable 402. The function of the limiting post 401 is to prevent the fixing block 204 from rotating with the threaded bolt 203. The groove is designed to facilitate the placement of the cable 402, and the cable 402 will not deviate during the winding process.

[0031] Operation method: Pass the cable 402 around the fifth rotating wheel 201, the first rotating wheel 306, the second rotating wheel 307, the third rotating wheel 308, the fourth rotating wheel 309 on one side of the motherboard 1 and the side wall of the fifth rotating wheel 201 on the other side of the motherboard 1. Rotate the first threaded post 301, the second threaded post 302, the third threaded post 303 and the fourth threaded post 304 respectively to adjust the height of the first rotating wheel 306, the second rotating wheel 307, the third rotating wheel 308 and the fourth rotating wheel 309 to press the cable 402 tight. Rotate the threaded bolt 203 on the top of the mounting plate 202 to make the threaded bolt 203 drive the fixing block 204 closer to the fifth rotating wheel 201, thereby fixing the cable 402 on the side wall of the fifth rotating wheel 201.

[0032] For example, if it is necessary to tighten the cable 402 on the left side of the motherboard 1, the cable 402 on the right side of the motherboard 1 can be fixed by the fixing component 2. Then, the third threaded post 303 is rotated to make the corresponding connecting plate 305 drive the third rotating wheel 308 to slide upward, thereby loosening the cable 402 between the second rotating wheel 307 and the fourth rotating wheel 309. Then, the second threaded post 302 is rotated to make the second rotating wheel 307 slide upward, thereby tightening the cable 402 on the left side of the motherboard 1. The upward sliding of the cable 402 between the second rotating wheel 307 and the fourth rotating wheel 309 will not affect the tightness of the cable 402 on the right side of the motherboard 1, thus completing the tightening of the cable 402 on the left side of the motherboard 1.

[0033] 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.
