The other side of the protective box has the same structure as the first side.

[0010] In one embodiment of this utility model, two guide rods are provided on both sides inside the protective box.

[0011] In one embodiment of this utility model, a plug is provided on one side of the power cord, and a connector is provided on the other side of the power cord. The outer wall of the power cord is slidably connected to the connector and the cleaning pad.

[0012] In one embodiment of this utility model, a connecting rope is provided at the corner of the protective box, and a gripping ring is provided at the end of the connecting rope.

[0013] In one embodiment of this utility model, the protective box is made of polyethylene.

[0014] In one embodiment of this utility model, a plurality of auxiliary grooves are provided on one side of the pressing plate.

[0015] In one embodiment of this utility model, the winding reel is made of polypropylene.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1) The included connecting rod facilitates easy access for users when pulling out the power cord. Note that a torsion spring is located at the connection between the rotating rod and the reel. When the user pulls out the power cord, the reel rotates, causing the gear ring to rotate ("clockwise for winding, counter-clockwise for unwinding" in this diagram). The counter-clockwise rotation of the gear ring, combined with the inclined rod structure and damping spring, allows for unwinding only counter-clockwise, facilitating cord extension. When the user releases the cord, the torsion spring causes the reel to wind up, but at this point, the connecting rod blocks the gear ring, preventing clockwise rotation and thus limiting the cord's movement. To prevent the cord from automatically resetting via the torsion spring after being pulled out, when the user needs to rewind the power cord after use, the user operates the pressing plate, causing it to rotate within the connecting frame, which in turn causes the connecting rod to separate from the toothed ring, contacting the limit position of the toothed ring. At this time, the torsion spring will drive the winding reel to rotate and rewind the power cord. When the user operates the pressing plate, the connecting rod, through the first hinge seat, the first fixed block, the second fixed block, and the second hinge seat, causes the damping rod spring to be pulled open and then store force. When the user finishes rewinding and releases the pressing plate, the damping rod spring will reset, which in turn causes the connecting rod to reset, thus realizing winding and fast winding and unwinding of the cord.

[0018] 2) The included cleaning pad allows for quick cleaning of the power cord during unwinding and rewinding, preventing excessive surface dirt. When the cleaning pad is in use for an extended period, the user can rotate the handle to turn the bidirectional screw. The screw, through its external thread and the engagement with the limit rod, causes the first and second connecting plates to move the auxiliary ring outwards, exposing the cleaning pad. The user can then tear off the cleaning pad, wash it, and replace it, thus achieving proper cleaning of the power cord. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Example

[0034] Please see Figure 1 - Figure 4 A power cord with a winding and unwinding structure includes a protective box 100, a winding and unwinding assembly 200, and a cleaning assembly 300.

[0035] Please refer to the details. Figure 1 The protective box 100 has rotating rods 110 on both the top and bottom of its inner wall.

[0036] Please see Figures 2-3The winding and unwinding assembly 200 includes a winding reel 210 rotatably connected between two rotating rods 110. A power cord 220 is installed inside the winding reel 210. Toothed rings 230 are provided at the top and bottom of the winding reel 210. A connecting frame 240 is embedded inside one end of the protective box 100. Two connecting rods 250 are hinged inside the connecting frame 240. The ends of the two connecting rods 250 are movably connected to the toothed rings 230. A first hinge seat 260 is provided on one side of each of the two connecting rods 250. A first fixing block is hinged inside the first hinge seat 260. A damping rod spring 270 is provided on one side of the first fixing block. A second fixing block is provided on one side of the damping rod spring 270. A second hinge seat 280 is hinged on one side of the second fixing block. A connecting frame 290 is provided on one side of the second hinge seat 280. A pressing plate 2910 is provided at one end of each of the two connecting rods 250.

[0037] In one specific embodiment, the connecting rod 250 facilitates the user's pulling out of the power cord 220. It's important to note that a torsion spring is installed at the connection between the rotating rod 110 and the reel 210. When the user pulls out the power cord 220, the reel 210 rotates simultaneously, causing the toothed ring 230 to rotate. In this embodiment, the toothed ring 230 rotates counter-clockwise to reel in the cord, and through the cooperation of the inclined rod structure of the connecting rod 250 and the damping spring 270, it can currently only rotate counter-clockwise to reel in the cord, making it easy for the user to pull out the power cord 220. When the user releases the cord, the torsion spring will cause the reel 210 to reel in the cord, but at this time, the connecting rod 250 blocks the toothed ring 230, preventing it from rotating clockwise, thus limiting the power cord 220's rotation. To prevent the power cord 220 from automatically resetting after being pulled out by the torsion spring, when the user needs to rewind the power cord 220 after use, the user can operate the pressing plate 2910 to rotate within the connecting frame 240, thereby causing the connecting rod 250 to separate from the toothed ring 230 and contact the limiting position of the toothed ring 230. At this time, the torsion spring will drive the winding reel 210 to rotate and rewind the power cord 220. When the user operates the pressing plate 2910, the connecting rod 250, through the first hinge seat 260, the first fixing block, the second fixing block, and the second hinge seat 280, causes the damping rod spring 270 to be pulled open and then store force. When the user finishes rewinding and releases the pressing plate 2910, the damping rod spring 270 will reset, thereby causing the connecting rod 250 to reset, thus achieving the purpose of winding and fast rewinding.

[0038] Please see Figure 4The cleaning component 300 includes a connector 310 disposed on one side of the protective box 100. A connecting ring 320 is disposed on one side of the connector 310. Auxiliary brackets 330 are disposed at both ends of the outer wall of the connecting ring 320. Connecting blocks 340 are disposed at the top and bottom of the two auxiliary brackets 330. A limit rod 350 is disposed between the two connecting blocks 340. A bidirectional lead screw 360 is rotatably connected to one side of another connecting block 340. A handle 370 is disposed through the remaining connecting block 340 on one side of the bidirectional lead screw 360. Two first connecting plates 380 are threadedly connected to the outer wall of the bidirectional lead screw 360. Two second connecting plates 390 are slidably connected to the outer wall of the limit rod 350. Two auxiliary rings 3910 are disposed between the first connecting plates 380 and the second connecting plates 390. A cleaning pad 3920 is pasted inside the two auxiliary rings 3910. The other side of the protective box 100 is provided with the same structure as the other side.

[0039] In one specific embodiment, the provided cleaning pad 3920 facilitates quick cleaning of the power cord 220 during cable unwinding and rewinding, preventing excessive surface dirt. Furthermore, when the cleaning pad 3920 is in prolonged use, the user can rotate the handle 370 to rotate the bidirectional lead screw 360. The bidirectional lead screw 360, through its external thread and engagement with the limiting rod 350, causes the first connecting plate 380 and the second connecting plate 390 to move the auxiliary ring 3910 outwards, thus exposing the cleaning pad 3920. The user can then tear off the cleaning pad 3920, clean it, and replace it, thereby achieving the purpose of cleaning the power cord 220.

[0040] Please see Figure 2 The protective box 100 has two guide rods 400 on both sides inside.

[0041] In one specific embodiment, the guide rod 400 facilitates the more stable winding of the power cord 220 into the take-up reel 210 when the take-up reel 210 is winding it up, thereby achieving the purpose of stable conveying.

[0042] Please see Figure 1 A plug 500 is provided on one side of the power cord 220, and a connector 600 is provided on the other side of the power cord 220. The outer wall of the power cord 220 is slidably connected to the connector 310 and the cleaning pad 3920.

[0043] In one specific embodiment, the provided plug 500 facilitates connection to an external socket, and the connector 600 is connected to the device to supply power, thereby improving work efficiency.

[0044] Please see Figure 1A connecting rope 700 is provided at the corner of the protective box 100, and a grip ring 800 is provided at the end of the connecting rope 700.

[0045] In one specific embodiment, the provided grip ring 800 allows users to carry the device more conveniently by using the grip ring 800 in conjunction with the connecting rope 700, thereby improving work efficiency and increasing portability.

[0046] Please see Figure 1 The protective box 100 is made of polyethylene.

[0047] In one specific embodiment, the presence of polyethylene allows users to easily utilize the robust and durable properties of polyethylene, making the protective box 100 more robust and durable, thus improving its stability.

[0048] Please see Figure 3 Several auxiliary grooves are provided on one side of the pressing plate 2910.

[0049] In one specific embodiment, the auxiliary groove allows the user to place their fingers into it during use, making it more comfortable to operate the pressing plate 2910 and improving its practicality.

[0050] Please see Figure 2 The reel 210 is made of polypropylene.

[0051] In one specific embodiment, the presence of polypropylene allows the winding reel 210 to be made more robust and durable during use, thus extending its service life.

[0052] In use, the connecting rod 250 facilitates the user's pulling out of the power cord 220. It's important to note that a torsion spring is installed at the connection between the rotating rod 110 and the take-up reel 210. When the user pulls out the power cord 220, the take-up reel 210 rotates simultaneously, causing the gear ring 230 to rotate. In this diagram, "clockwise for take-up and counter-clockwise for unwinding," the gear ring 230 rotates counter-clockwise. Through the coordination of the inclined rod structure of the connecting rod 250 and the damping spring 270, the gear ring 230 can currently only rotate counter-clockwise for unwinding, facilitating... When the user pulls out the power cord 220 and releases it, the torsion spring will cause the reel 210 to wind up. However, at this time, the connecting rod 250 abuts against the toothed ring 230, preventing it from rotating clockwise, thus limiting the power cord 220 to prevent it from automatically resetting after being pulled out by the torsion spring. When the user needs to wind up the power cord 220 after use, the user moves the pressing plate 2910, which rotates within the connecting frame 240, causing the connecting rod 250 to separate from the toothed ring 230 and contact the toothed ring 240. When the limit switch is set to 30, the torsion spring will drive the winding reel 210 to rotate and wind up the power cord 220. When the user pulls the pressing plate 2910, the connecting rod 250, through the first hinge seat 260, the first fixing block, the second fixing block, and the second hinge seat 280, causes the damping rod spring 270 to be pulled open and then store force. When the user releases the pressing plate 2910 after winding, the damping rod spring 270 will return to its original position, which in turn causes the connecting rod 250 to return to its original position, thereby achieving the purpose of winding and unwinding the cord and quickly winding it up. Finally, the cleaning pad 3920 facilitates the unwinding of the power cord 220. When winding and unwinding the cord, the cleaning pad 3920 can be used to quickly clean it, avoiding excessive dirt on its surface. When the cleaning pad 3920 is used for a long time, the user can turn the handle 370 to rotate the bidirectional lead screw 360. The bidirectional lead screw 360, through the cooperation of the external thread and the limit rod 350, causes the first connecting plate 380 and the second connecting plate 390 to move the auxiliary ring 3910 outward, thereby exposing the cleaning pad 3920. The user can then tear off the cleaning pad 3920, clean it, and replace it, thus achieving the purpose of cleaning the power cord 220.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
