Description

Technical Field

[0001] This application relates to the field of load-bearing technology, and more specifically, to a cable-bearing device for charging piles that prevents dragging. Background Technology

[0002] The anti-drag charging pile cable support device is a support and protection device adapted to the charging pile cable. It can support and lift the charging cable of the charging pile, reduce the drag stress caused by the cable's own weight or external pulling force, and prevent the cable from friction and wear with the ground or loosening at the interface due to dragging. It is suitable for outdoor charging piles, parking lot charging spaces and other scenarios. The support position can be flexibly adjusted according to the cable length and usage requirements to ensure the integrity and safety of the cable in daily use and provide support for the stable charging operation of the charging pile.

[0003] In actual operation, the anti-drag charging pile cable carrying device is difficult to conveniently fix the length and quickly retract when adjusting the cable carrying length. During the winding and unwinding process, the charging pile cable is also prone to shaking, resulting in uneven winding. This makes the cable length adjustment operation inconvenient and unable to flexibly adapt to different usage needs of the charging pile cable, affecting the stable carrying capacity and convenient adjustment of the cable. Utility Model Content

[0004] The purpose of this application is to provide a charging pile cable carrying device that prevents dragging, thereby solving the technical problems mentioned in the background art.

[0005] This application provides a charging pile cable carrying device to prevent dragging, including a winding box. A fixed box is fixedly connected to the front end of the winding box. A fixed shaft is fixedly connected inside the fixed box and extends into the winding box. A ratchet is rotatably connected to one side of the outer wall of the fixed shaft and is located inside the fixed box. An extension ring is fixedly connected to the side wall of the ratchet. A rotating ring is fixedly connected to one end of the extension ring and extends into the winding box. A coil spring is provided inside the rotating ring. A pair of limiting blocks are fixedly connected to the lower part of the fixed box. A movable cylinder is slidably connected between the two limiting blocks. An extension cylinder is slidably inserted into the end face of the movable cylinder near the ratchet. A connecting spring is fixedly connected inside the movable cylinder and the extension cylinder. A tension strap is fixedly connected to the outer wall of the rotating ring and extends out of the winding box.

[0006] Optionally, one end of the coil spring is fixedly connected to the fixed shaft, and the other end of the coil spring is fixedly connected to the rotating ring.

[0007] Optionally, a fixed cylinder communicating with the fixed box is fixedly connected to the lower part of the front end face of the fixed box, and a pressing rod is fixedly connected to the front end face of the movable cylinder, and the pressing rod extends out of the fixed cylinder. A positioning spring is sleeved around the pressing rod, and the two ends of the positioning spring are fixedly connected to one side of the inside of the fixed cylinder and the movable cylinder, respectively.

[0008] Optionally, a movable groove is provided at the upper rear of the inside of the winding box, a fixed rod is fixedly connected inside the movable groove, and a pressing piece is slidably connected to the outer wall of the fixed rod.

[0009] Optionally, a support spring is sleeved around the fixed rod, and the two ends of the support spring are fixedly connected to the lower part of the moving groove and the pressing piece, respectively.

[0010] Optionally, a connecting piece is fixedly connected to the lower end face of the pull strip, and a fixing sleeve is fixedly connected to both ends of the connecting piece. An installation ring is fixedly connected to one side of the lower end of the fixing sleeve, and a fixing strap is fixedly connected to the other side of the lower end of the fixing sleeve. Velcro is sewn onto the lower side wall of the fixing strap.

[0011] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0012] This application utilizes an outward-pulling pull band to drive a rotating ring around a fixed axis. The coil spring stretches and stores energy, while the ratchet gear rotates. Simultaneously, the extension cylinder slides along the moving cylinder without affecting the rotation, until the pull band is pulled to the appropriate length. After pulling stops, the spring's rebound force drives the ratchet gear to rotate in the opposite direction. The extension cylinder, under the action of the connecting spring, resets and engages with the ratchet gear teeth, effectively limiting reverse rotation and fixing the pull band length. To shorten or retract, pressing the pressing rod causes the moving cylinder to slide, disengaging the extension cylinder from the ratchet gear. The coil spring releases its stored energy, retracting the pull band. Releasing the pressing rod resets the components, making operation convenient. During winding, the pressing plate, under the action of the support spring, adheres to the pull band, increasing winding stability and preventing it from wobbling within the winding box. The device is easy to use, flexible in winding and unwinding, and suitable for the needs of charging pile cables. Attached Figure Description

[0017] The present application will be further described in detail below with reference to the accompanying drawings.

[0018] Reference Figures 1-3 This application provides an anti-drag charging pile cable carrying device, including a winding box 1. A fixing box 2 is fixedly connected to the front end of the winding box 1. A fixing shaft 4 is fixedly connected inside the fixing box 2 and extends into the winding box 1. A ratchet 8 is rotatably connected to one side of the outer wall of the fixing shaft 4 and is located inside the fixing box 2. An extension ring 7 is fixedly connected to the side wall of the ratchet 8. A rotating ring 5 is fixedly connected to one end of the extension ring 7 and extends into the winding box 1. A coil spring 6 is provided inside the rotating ring 5. One end of the coil spring 6 is fixedly connected to the fixing shaft 4, and the other end of the coil spring 6 is fixedly connected to the rotating ring 5. A pair of limiting blocks 9 are fixedly connected to the lower part of the inside of the fixing box 2. A movable cylinder 10 is slidably connected, and an extension cylinder 11 is slidably inserted into the end face of the movable cylinder 10 near the ratchet 8. A connecting spring 12 is fixedly connected inside the movable cylinder 10 and the extension cylinder 11. A tension belt 19 is fixedly connected to the outer wall of the rotating ring 5, and the tension belt 19 extends out of the winding box 1. By pulling the tension belt 19 outward, the rotating ring 5 can be driven to rotate around the fixed shaft 4. The coil spring 6 is stretched and stored. At the same time, when the ratchet 8 rotates, the extension cylinder 11 slides along the movable cylinder 10 without affecting the rotation, until the tension belt 19 is pulled out to the appropriate length. After the pulling stops, the spring 6 rebounds and drives the ratchet 8 to rotate in the opposite direction. Under the action of the connecting spring 12, the extension cylinder 11 resets and is locked into the tooth gap of the ratchet 8, which can stably limit the reverse rotation and fix the length of the tension belt 19.

[0019] A fixed cylinder 3, which is connected to the fixed box 2, is fixedly connected to the lower front end of the fixed box 2. A pressing rod 13 is fixedly connected to the front end of the movable cylinder 10, and the pressing rod 13 extends out of the fixed cylinder 3. A positioning spring 14 is sleeved around the pressing rod 13, and the two ends of the positioning spring 14 are fixedly connected to one side of the inside of the fixed cylinder 3 and the movable cylinder 10, respectively. When it is necessary to shorten or retract, pressing the pressing rod 13 causes the movable cylinder 10 to slide, so that the extension cylinder 11 disengages from the ratchet 8. The coil spring 6 releases its stored force to retract the pulling band 19. After releasing the pressing rod 13, the positioning spring 14 drives the component to reset and re-fix it. The operation is convenient.

[0020] A movable groove 15 is provided at the upper rear of the inside of the winding box 1. A fixed rod 16 is fixedly connected inside the movable groove 15. A pressing piece 17 is slidably connected to the outer wall of the fixed rod 16. A support spring 18 is sleeved around the fixed rod 16. The two ends of the support spring 18 are fixedly connected to the lower part of the movable groove 15 and the pressing piece 17, respectively. During the winding process, the pressing piece 17 adheres to the pulling strip 19 under the action of the support spring 18, which can increase the stability of winding and unwinding and prevent it from shaking inside the winding box 1.

[0021] A connecting piece 20 is fixedly connected to the lower end of the pull strap 19. Both ends of the connecting piece 20 are fixedly connected to a fixing sleeve 21. A mounting ring 22 is fixedly connected to one side of the lower end of the fixing sleeve 21. A fixing strap 23 is fixedly connected to the other side of the lower end of the fixing sleeve 21. Velcro 24 is sewn onto the lower side wall of the fixing strap 23. After the cable passes through the fixing sleeve 21, it passes through the fixing strap 23, around the mounting ring 22, and is fixed by the Velcro 24. This allows the cable to form a stable connection with the fixing sleeve 21, the connecting piece 20, and the pull strap 19, preventing the cable from loosening during use.

[0022] Working principle: The operator installs the winding box 1 at the designated location. When installing the charging pile cable, first pass the charging pile cable through the inside of the fixing sleeves 21 at both ends of the connecting piece 20, adjust the position of the cable inside the fixing sleeves 21 so that the part of the cable that needs to be supported is aligned with the fixing sleeves 21, and then wrap the fixing strap 23 on the lower side of the fixing sleeve 21 around the mounting ring 22. The Velcro 24 on the lower side wall of the fixing strap 23 will stick and fix the fixing strap 23, so that the cable forms a stable connection with the fixing sleeve 21, the connecting piece 20 and the pull strap 19.

[0023] In use, pulling the pull strap 19 outward causes the rotating ring 5 to rotate around the fixed shaft 4. The coil spring 6 inside the rotating ring 5 is stretched and stores energy. Simultaneously, the rotating ring 5 drives the extension ring 7 and the ratchet 8 to rotate synchronously. During the rotation of the ratchet 8, the inclined surface of the ratchet teeth pushes the extension cylinder 11 to slide along the moving cylinder 10, compressing the connecting spring 12. The extension cylinder 11 slides in the gap between the teeth of the ratchet 8 without affecting the rotation of the ratchet 8, until the pull strap 19 is pulled out to the length suitable for the cable. When fixing the length of the pull strap 19, stop pulling the pull strap 19. The rebound force of the coil spring 6 causes the rotating ring 5, the extension ring 7, and the ratchet 8 to rotate in the opposite direction. At this time, the extension cylinder 11 returns to its original position under the elastic force of the connecting spring 12, and is engaged between the planes of the teeth of the ratchet 8, restricting the reverse rotation of the ratchet 8, thereby fixing the position of the rotating ring 5 and the pull strap 19.

[0024] If it is necessary to shorten or retract the length of the pull belt 19, press the pressing rod 13 on the outside of the fixing cylinder 3. The pressing rod 13 drives the moving cylinder 10 to slide along the two limit blocks 9. The positioning spring 14 is stretched, and the moving cylinder 10 drives the extension cylinder 11 to move away from the tooth gap of the ratchet 8 and move towards the extension ring 7. The limit on the ratchet 8 is released, the coil spring 6 releases its stored force, and drives the rotating ring 5 to rotate in the opposite direction, retracting the pull belt 19 into the winding box 1 until the cable length is adjusted to a suitable state. Release the pressing rod 13, the positioning spring 14 rebounds and pulls the moving cylinder 10 and the extension cylinder 11 to reset, and re-engage with the tooth gap of the ratchet 8 for fixation.

[0025] When the pull belt 19 is wound up, the pressing plate 17 at the upper rear of the inside of the winding box 1 adheres to the pull belt 19 under the elastic force of the support spring 18, increasing the stability of the pull belt 19 during winding and unwinding, and preventing it from shaking inside the winding box 1.

[0026] To remove the cable, first unfasten the Velcro 24 on the retaining strap 23, loosen the retaining strap 23 from the cable, and then remove the cable from the retaining sleeve 21 to complete the separation of the cable from the device.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
