[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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.

[0023] Example 1

[0024] As attached Figures 1 to 4The cable retractor shown includes a base 1, which serves as the foundation of the entire device. The base 1 needs sufficient strength and stability to support other components and ensure the stability of the device during use. A clamping mechanism 2 is provided on the upper surface of the base 1. The clamping mechanism 2 includes a vertical plate 21, which is slidably connected to the upper surface of the base 1. A roller hole 22 is provided on the right surface of the vertical plate 21. A roller 23 passes through the inner surface of the roller hole 22 and is slidably connected to the roller 23. A take-up roller 24 is fixedly connected to the outer arc surface of the roller 23. A toothed groove 25 is arranged in a circumferential array on the right surface of the roller hole 22. A motor 26 is fixedly connected to the right surface of the vertical plate 21. This mechanism includes the vertical plate 21, roller hole 22, roller 23, take-up roller 24, toothed groove 25, motor 26, and gear 27. The vertical plate 21 is slidably connected to the upper surface of the base 1, allowing the vertical plate 21 to move within a certain range to accommodate cables of different lengths. A roller 23 is installed inside the roller hole 22. A take-up roller 24 is fixedly connected to the outer arc surface of the roller 23 for winding the cable. A toothed groove 25 meshes with a gear 27 of a motor 1 26. The rotation of the motor 1 26 drives the take-up roller 24 to realize the winding and unwinding of the cable. The output shaft of the motor 1 26 is fixedly connected to a gear 27, which meshes with the toothed groove 25. A U-shaped rod 28 is fixedly connected to the upper surface of the base 1. The U-shaped rod 28 passes through the vertical plate 21 and is slidably connected to the vertical plate 21. A bidirectional lead screw 29 is rotatably connected to the upper surface of the U-shaped rod 28. A motor 210 is fixedly connected to the right surface of the base 1. The output shaft of the motor 210 is fixedly connected to the bidirectional lead screw 29. The bidirectional lead screw 29 passes through the vertical plate 21 and is threadedly connected to the vertical plate 21. This rod passes through the vertical plate 21 and is slidably connected to it, ensuring the stability and guidance of the vertical plate 21 when winding and unwinding the cable. The upper surface of the U-shaped rod 28 is rotatably connected to a bidirectional lead screw 29, which is used to adjust the position of the vertical plate 21. The upper surface of the base 1 is fixedly connected to a wire straightener 211, which is located in front of the shaft roller 23. It is used to organize and guide the cable when winding and unwinding the cable, ensuring that the cable is neatly wound on the take-up roller shaft 24, and avoiding cable tangling or damage.

[0025] In this cable retractor for power distribution maintenance, the clamping mechanism 2 is used to fix and drive the take-up roller 24. The vertical plate 21 can slide on the base 1, and this sliding connection design facilitates its position adjustment. The roller 23 passes through the roller hole 22 on the right surface of the vertical plate 21 and can slide. The take-up roller 24 is fixed on the outer arc surface of the roller 23 to realize the take-up and take-up of the cable. The toothed grooves 25 are arranged in a circumferential array on the right surface of the roller shaft hole 22. The motor 26 is fixed on the right surface of the vertical plate 21. The gear 27 connected to its output shaft meshes with the toothed grooves 25. When the motor 26 starts, it drives the shaft roller 23 and the take-up roller shaft 24 to rotate through the meshing transmission of the gear 27 and the toothed grooves 25, thereby performing cable winding or unwinding operations. The vertical plate 21 is threadedly connected to the bidirectional lead screw 29, and the U-shaped rod 28 provides guidance. The vertical plate 21 will slide in a straight line along the U-shaped rod 28 and the surface of the base 1, thereby adjusting the position of the take-up roller shaft 24 to meet the needs of cable winding and unwinding of different lengths. During the cable winding and unwinding process, the cable straightener 211 can sort and straighten the cable to prevent the cable from getting tangled or knotted during winding and unwinding, making the cable winding and unwinding smoother and more orderly, and improving the efficiency and quality of winding and unwinding operations.

[0026] Example 2

[0027] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0028] In a preferred embodiment, a cable winding mechanism 3 is provided on the upper surface of the base 1. The cable winding mechanism 3 includes an inclined plate 31, which is fixedly connected to the upper surface of the base 1. A cable guiding groove 32 is formed on the upper surface of the inclined plate 31. The cable winding mechanism 3 mainly consists of the inclined plate 31, which is firmly fixed to the upper surface of the base 1 to ensure that there will be no loosening or displacement during use. The cable guiding groove 32 is ingeniously formed on the upper surface of the inclined plate 31. The design of the cable guiding groove 32 is not arbitrary; its shape has been precisely considered and calculated. The width of the groove is set according to the diameter range of common cables, which can accommodate cables of different thicknesses and ensure that the cables are not too loose and tangled in the groove. The depth of the cable guiding groove 32 has also been determined through repeated experiments to ensure that the cables can be stably placed in the groove and will not easily jump out. The length of the cable guide trough 32 is determined based on the overall dimensions of the inclined plate 31 and the actual needs of cable storage. Extending from one end of the inclined plate 31 to the other, it forms a smooth guiding path, guiding the cable to be stored orderly along a predetermined direction. Simultaneously, the inner wall of the cable guide trough 32 is smoothed using a special polishing process to reduce friction between the cable and the cable during loading and unloading, preventing damage to the cable sheath and extending the cable's lifespan. Furthermore, the edges of the cable guide trough 32 are rounded to prevent the cable from being scratched by sharp edges when entering or exiting the trough. These carefully designed details enable the cable winding mechanism 3 to efficiently achieve orderly cable storage and management in practical use.

[0029] In a preferred embodiment, a slide rod 33 extends through and is slidably connected to the rear surface of the base 1. A baffle 34 is fixedly connected to the front surface of the slide rod 33. One end of the slide rod 33 is fixedly connected to a spring 35, and the other end of the base 1 is fixedly connected to the spring 35. The spring 35 plays a crucial role in this structure, providing elastic force. When the slide rod 33 slides under external force, the spring 35 is stretched or compressed accordingly. According to Hooke's Law, the spring 35 generates an elastic force opposite to the external force. This elastic force causes the slide rod 33 to return to its initial position after the external force is removed, thus realizing the structure's reset function. This reset function is essential in many practical applications, such as automatic rebound devices and shock absorption systems, all of which rely on the elastic restoring force provided by the spring to ensure the continuous and stable operation of the entire structure, improving its efficiency and reliability.

[0030] In a preferred embodiment, an arc-shaped groove 4 is formed on the left surface of the vertical plate 21. An arc-shaped plate 5 is slidably connected to the inner surface of the arc-shaped groove 4. One end of the arc-shaped plate 5 is fixedly connected to one end of the second spring 6, and the other end of the arc-shaped groove 4 is fixedly connected to the other end of the second spring 6. This connection method employs a special process, ensuring a firm and reliable bond between the two, preventing loosening during normal use. Simultaneously, the other end of the second spring 6 is fixedly connected to the arc-shaped groove 4. The second spring 6 has an appropriate elastic coefficient, providing the arc-shaped plate 5 with a certain elastic support force to maintain a relatively stable state during sliding. Furthermore, it can adapt to the movement changes of the arc-shaped plate 5 through its own expansion and contraction when subjected to external forces, thereby fulfilling certain functional requirements, such as buffering and resetting.

[0031] The working process of this utility model is as follows: First, as can be seen from the figure, there are two sets of vertical plates 21. Therefore, when the bidirectional lead screw 29 rotates clockwise, the two sets of vertical plates 21 will separate to both sides. After the vertical plates 21 separate to both sides, the shaft roller 23 will disengage from the roller shaft hole 22 and fall downwards due to gravity. After falling onto the inclined plate 31, due to gravity and the setting of the inclined plate 31, the shaft roller 23 and the take-up roller shaft 24 roll down to the direction of the baffle 34. The baffle 34 will drive the slide rod 33 to move backward and compress the spring 35, restricting the take-up roller shaft 24 to a fixed position. At the same time, the arc plate 5 is without the take-up roller shaft. After being squeezed by 24, the take-up roller 24 is ejected by the elastic force of spring 6. When it is necessary to reposition the take-up roller 24, the empty take-up roller 24 can be placed directly on the arc plate 5. By rotating the bidirectional screw 29 counterclockwise, the two sets of vertical plates 21 are brought together in the middle. The take-up roller 24 will squeeze the arc plate 5 into the arc groove 4 and compress the spring 6. At this time, the gear 27 will mesh with the tooth groove 25. The motor 1 26 drives the shaft roller 23 to rotate, and the shaft roller 23 drives the take-up roller 24 to rotate, which works in conjunction with the wire winding machine 211 to take up the wire. The above is the working principle of this cable take-up and take-up device for power distribution operation and maintenance.
