Description

Technical Field

[0001] This utility model belongs to the technical field of cable tensioners, and specifically relates to a ratchet cable tensioner. Background Technology

[0002] The ratchet cable tensioner is a highly efficient and convenient rope tightening tool, widely used in power line construction, cargo bundling, and outdoor operations. Its core design utilizes a ratchet mechanism, achieving rapid tightening and locking of the rope through unidirectional rotation to prevent loosening. Operation is simple: just pull the handle to tighten the rope and release the ratchet to release it—effortless and safe. This tool is compact, durable, and compatible with various rope sizes, making it an ideal choice for improving work efficiency and safety.

[0003] However, existing tighteners still have some shortcomings. When using the collector, since the yarn needs to be recycled back into the tightener later, if the yarn is loose and not tightened during the recycling process, it will also be loose when it is recycled into the tightener, which reduces the tightness of the yarn winding and affects the convenience of reusing the yarn later.

[0013] In summary, the present invention has the following main advantages:

[0014] Firstly, during use, the crank handle can drive the turntable to rotate, which in turn drives the connecting shaft to rotate the circular plate and ratchet body, thus allowing for the winding and unwinding of the yarn. When winding the yarn later, to improve the tightness of the winding, the user can turn the screw. The shaft can make the end of the screw rotate in place, and the clamping plate will be pushed or pulled accordingly. This allows the user to adjust the spacing of the clamping plate. By having the clamping plate in contact with the yarn, the yarn will have resistance during winding, so that the yarn will remain taut during winding, which can effectively improve the tightness of the winding. At the same time, the easy adjustment of the clamping plate spacing also makes it convenient for the user to use yarn of different thicknesses.

[0015] Secondly, to prevent the cable from falling off during installation, the cable can be placed at the top of the pressure plate first, and then the pressure plate can be slid through the first groove so that the pressure plate presses on the cable. When the cable is retrieved, it will be wrapped around the outside of the pressure plate. While restricting the pressure plate position, it can also make the pressure plate press on the cable more secure, which can effectively prevent the cable from falling off during use. The snap-fit ​​principle makes it easy for users to disassemble and assemble the base plate later, so that users can clean or maintain its internal structure through the bottom of the protective shell.

Detailed Implementation

[0022] Example

[0023] refer to Figures 1 to 5This embodiment of a ratchet cable tensioner includes a protective shell 1. A circular plate 2 is rotatably connected to the inner wall of the protective shell 1. A ratchet body 3 is fixedly connected to the inner wall of the circular plate 2. A connecting shaft 6 is fixedly connected to the rear side of the circular plate 2. The rear side of the connecting shaft 6 protrudes from the protective shell 1. A turntable 9 is fixedly connected to the rear side of the connecting shaft 6. A crank handle 10 is provided on the rear side of the turntable 9. A cable 26 is provided on one side of the ratchet body 3. A connecting hole 25 matching the cable 26 is opened on one side of the protective shell 1. The cable 26 is located inside the connecting hole 25. A first mounting block 15 and a second mounting block 17 are snapped onto one side of the protective shell 1. A fixing block 21 is fixedly connected to one side of the first mounting block 15. A screw hole 24 is opened on the front side of the fixing block 21. A screw rod 23 is threadedly connected to the inner side of the screw hole 24. A rotating shaft 22 is fixedly connected to the rear side of the screw rod 23. A clamping plate 19 is slidably connected to one side of the second mounting block 17. The rear side of the rotating shaft 22 is rotatably connected to the front side of the clamping plate 19. In use, the crank handle 10 can drive the turntable 9 to rotate, so that the connecting shaft 6 can drive the circular plate 2 and the ratchet body 3 to rotate, thereby processing the winding and unwinding of the yarn 26. When winding the yarn 26 later, in order to improve the tightness of the winding of the yarn 26, the user can turn the screw 23. The rotating shaft 22 can make the end of the screw 23 rotate in place, and the clamping plate 19 will be pushed or pulled accordingly, which makes it easier for the user to adjust the spacing of the clamping plate 19. By the way that the clamping plate 19 is in contact with the yarn 26, the yarn 26 can have resistance when winding, so that the yarn 26 can be kept taut during the winding, which can effectively improve the tightness of the winding of the yarn 26, thereby improving the stability of the winding of the yarn 26.

[0024] refer to Figures 1 to 4 The protective shell 1 has a second slot 14 on one side. The other side of the first mounting block 15 and the second mounting block 17 are fixedly connected to a second locking block 16 that matches the second slot 14. The second locking block 16 is engaged inside the second slot 14. The second mounting block 17 has a third sliding groove 18 that matches the clamping plate 19 on one side. The clamping plate 19 is slidably connected to one side of the second mounting block 17 through the third sliding groove 18. Due to the presence of the second locking block 16, the engagement of the second locking block 16 can effectively fix the positions of the first mounting block 15 and the second mounting block 17, thereby preventing their positions from shifting. It also makes it easier for the user to remove the first mounting block 15 and the second mounting block 17 for later maintenance.

[0025] refer to Figure 4A pressure plate 5 is slidably connected to the inner wall of the circular plate 2. A first groove 4 matching the pressure plate 5 is provided on the inner wall of the circular plate 2. The pressure plate 5 is slidably connected to the inner wall of the circular plate 2 through the first groove 4. The position of the pressure plate 5 corresponds to the position of the ratchet. When installing the line 26, in order to prevent the line 26 from falling off, the line 26 can be placed at the top of the pressure plate 5 first, and then the pressure plate 5 can be slid through the first groove 4 so that the pressure plate 5 presses on the line 26. When retrieving the line 26, the line 26 will be wrapped around the outside of the pressure plate 5. While restricting the position of the pressure plate 5, it can also make the pressure of the pressure plate 5 on the line 26 more secure, which can effectively prevent the line 26 from falling off when using it.

[0026] refer to Figure 4 and Figure 5 The bottom of the protective shell 1 is snapped with a base plate 12, and the bottom of the protective shell 1 is fixedly connected with a first locking block 11. The first locking block 11 is fixedly connected to the four sides near the corner of the bottom of the protective shell 1. The top of the base plate 12 is provided with a first locking groove 13 that matches the first locking block 11. The first locking block 11 is snapped into the inside of the first locking groove 13. The snapping principle facilitates the user to disassemble and assemble the base plate 12 in the future, so that the user can clean or maintain its internal structure through the bottom of the protective shell 1.

[0027] refer to Figure 3 and Figure 4 The protective shell 1 has a second sliding groove 7 on its rear side. The second sliding groove 7 is circular in shape. A slider 8 is slidably connected to the inner side of the second sliding groove 7. The rear side of the slider 8 is fixedly connected to the front side of the turntable 9. The connecting shaft 6 is located on the inner side close to the slider 8. Due to the presence of the slider 8, the slider 8 can provide secondary support and traction to the front side of the turntable 9 without hindering the rotation of the turntable 9, thereby effectively improving the stability of the rotation of the turntable 9.

[0028] refer to Figure 2 A rubber pad 20 is fixedly connected to the inner wall of the clamping plate 19. The rubber pad 20 is five millimeters thick and covers the inner wall of the clamping plate 19. The line body 26 is located on the inner side close to the clamping plate 19. Due to the presence of the rubber pad 20, which is made of rubber, it has good elasticity and rubber anti-slip resistance, which can effectively improve the stability of the traction of the line body 26 and also prevent the line body 26 from being abraded by the clamping plate 19 during the recycling process.

[0029] refer to Figure 1A rectangular opening 27 is provided on the front side of the protective shell 1, which communicates with the inside of the protective shell 1. A transparent glass 28 is fixedly connected to the inside of the rectangular opening 27, covering the inside of the rectangular opening 27. A handle 29 is fixedly connected to the front side of the protective shell 1. The handle 29 has rounded corners. Due to the opening of the rectangular opening 27, the user can directly view the inside of the protective shell 1 through the transparent glass 28 without opening the bottom plate 12, which is conducive to the user's constant observation of the winding and unwinding of the cable 26, thereby improving the safety of the cable 26.

[0030] Operating principle and advantages: During use, the crank handle 10 drives the turntable 9 to rotate, which in turn drives the connecting shaft 6 to rotate the circular plate 2 and the ratchet body 3, thereby enabling the winding and unwinding of the yarn 26. To improve the tightness of the yarn 26 during later winding, the user can turn the screw 23. The rotating shaft 22 allows the end of the screw 23 to rotate in place, and the clamping plate 19 will be pushed or pulled accordingly. This allows the user to adjust the spacing of the clamping plate 19. The clamping plate 19, in contact with the yarn 26, provides resistance during winding, thus facilitating the winding process. Maintaining a taut state during this period effectively improves the tightness of the rewinding of the yarn 26, thereby enhancing the stability of the yarn 26 winding. Due to the presence of the second locking block 16, its engagement effectively secures the positions of the first mounting block 15 and the second mounting block 17, preventing positional shifts. This also facilitates the user's later removal of the first mounting block 15 and the second mounting block 17 for maintenance. When installing the yarn 26, to prevent it from falling off, it can be placed at the top of the pressure plate 5, and then... A sliding groove 4 slides the pressure plate 5 so that the pressure plate 5 presses onto the wire 26. When the wire 26 is retracted, it will wrap around the outside of the pressure plate 5. While restricting the position of the pressure plate 5, it also makes the pressure of the pressure plate 5 on the wire 26 more secure, which can effectively prevent the wire 26 from falling off during use. The snap-fit ​​principle facilitates the user's later disassembly and assembly of the base plate 12, so that the user can clean or maintain its internal structure through the bottom of the protective shell 1. Due to the presence of the slider 8, the slider 8 can provide secondary support to the front side of the turntable 9 without hindering the rotation of the turntable 9. The support and traction effectively improve the stability of the turntable at position 9. Due to the presence of the rubber pad 20, which is made of rubber and has good elasticity and rubber anti-slip resistance, it can effectively improve the stability of the traction at position 26 of the line and also prevent the line 26 from being abraded by the clamping plate 19 during the retrieval. Due to the opening of the rectangular opening 27, the user can directly view the inside of the protective shell 1 through the transparent glass 28 without opening the bottom plate 12, which is conducive to the user to observe the retrieval and release of the line 26 at all times, thereby improving the safety of the line 26 in use.
