Description

Technical Field

[0001] The present application relates to the technical field of cable reels, and in particular to a novel cable reel. Background Art

[0002] Power cord reels are commonly used to extend the power supply for appliances used indoors and outdoors. Most cord reels currently on the market utilize a circular, rotating cable drawer to store the cords. The reel's front receptacle also rotates with the reel.

[0003] If the user wants to move the cord reel by adjusting the extension length of the cord reel's power cord, they must first unplug the appliance, then retract the cord reel to the desired length. Once the cord reaches the desired length and position, they can then plug the appliance back into the reel. This process is relatively cumbersome. Furthermore, if the user forgets to unplug the appliance before moving the reel, the plug will rotate with the reel, causing the appliance's power cord to become twisted and entangled, potentially posing a risk. Based on this, the inventors developed a new type of cord reel with a fixed central socket. Summary of the Invention

DETAILED DESCRIPTION

[0037] The present application is further described in detail below with reference to the accompanying drawings.

[0038] The embodiment of the present application discloses a novel cable reel.

[0040] The bracket 11 is a special-shaped structure, wherein the bracket 11 can suspend the cable tray 16 so that the cable tray 16 can rotate to retract and release the power cord 17.

[0041] Reference Figure 2 A fixed shaft 111 is provided on the bracket 11, and one end of the central fixed shaft 12 is detachably connected and fixed to the fixed shaft 111, wherein the detachable connection includes but is not limited to plug-in, clip-on, threaded connection, etc.

[0042] The power source dynamic-stationary conversion structure 13 is disposed on the other end of the central stationary shaft 12 , wherein the hub 14 is rotationally connected to the central stationary shaft 12 through the power source dynamic-stationary conversion structure 13 .

[0043] Reference Figures 3 to 5 The power source dynamic-static conversion structure 13 includes two or three groups of dynamic-static components 131 and an insulating plate 132 provided between two adjacent groups of dynamic-static components 131;

[0044] If there are two sets of movable and fixed components 131 , the two sets of movable and fixed components 131 are respectively used to connect the live wire L and the neutral wire N of the power supply, so as to realize the electrical connection between the power cord 17 and the socket board 15 .

[0045] If there are three sets of movable and fixed components 131 , the three sets of movable and fixed components 131 are respectively used to connect the live wire L, the neutral wire N and the ground wire E of the power supply, so as to realize the electrical connection between the power cord 17 and the socket board 15 .

[0046] Specifically, refer to Figure 5 and Figure 6 In this embodiment, the power supply dynamic-static conversion structure 13 includes three groups of dynamic-static components 131 and two groups of insulating plates 132. The two groups of insulating plates 132 have jacks distributed between the three groups of dynamic-static components 131 to achieve insulation between the three groups of dynamic-static components 131.

[0047] Reference Figures 6 to 8The movable and fixed assembly 131 includes a base plate 1311, a spring piece 1312 and an upper plate 1313 that are electrically connected to each other, wherein the base plate 1311 is fixedly connected to the upper plate 1313. Preferably, the base plate 1311 and the upper plate 1313 are plugged in. Specifically, a plug-in plate 1314 is provided on the base plate 1311, and a slot 1315 is provided on the upper plate 1313. The plug-in plate 1314 is plugged into the slot 1315 to realize the plug-in connection between the base plate 1311 and the upper plate 1313.

[0048] The spring piece 1312 is located between the bottom plate 1311 and the upper plate 1313, and the bottom plate 1311 and the upper plate 1313 clamp the spring piece 1312. The bottom plate 1311, the spring piece 1312, and the upper plate 1313 are all circular in circumferential direction, and the bottom plate 1311 and the upper plate 1313 can rotate relative to the spring piece 1312. In addition, the spring piece 1312 has an overall bow-shaped, wavy, or arc-shaped structure, etc., so that the bottom plate 1311 and the upper plate 1313 can better contact the spring piece 1312 and maintain electrical connection.

[0049] Reference Figure 8 The spring piece 1312 is provided with a stopper 1316, which can be used to electrically connect to the socket board 15. Figure 4 and Figure 6 A stopping groove 121 is provided on the central fixed shaft 12, and a stopping piece 1316 is passed through the stopping groove 121. The spring piece 1312 is fixedly connected to the central fixed shaft 12 through the stopping piece 1316 and the stopping groove 121, wherein the stopping piece 1316 can serve as a fixed wire terminal on the spring piece 1312, and is used to realize electrical connection with the socket board 15 through wires.

[0050] Reference Figure 5 and Figure 8 The hub 14 is mounted on the central fixed shaft 12 and can rotate on the central fixed shaft 12. The hub 14 is fixedly connected to the upper plate 1313. Figure 3 Specifically, a spline 1317 is formed on one end of the upper plate 1313, and a keyway 141 is defined on the hub 14. The spline 1317 is inserted into the keyway 141 to achieve a fixed connection between the upper plate 1313 and the hub 14. A dynamic envelope terminal 1318 is formed on the other end of the upper plate 1313. The dynamic envelope terminal 1318 is used to be fixedly connected to the wire of the power cord 17 to achieve an electrical connection between the power supply dynamic-stationary conversion structure 13 and the power cord 17.

[0051] Reference Figure 4 and Figure 7Socket plate 15 is provided with a plurality of sockets and is fixedly connected to central fixed shaft 12. Specifically, central fixed shaft 12 is formed with a connecting rod 122, which passes through socket plate 15 and is coaxial with central fixed shaft 12 to prevent relative rotation between socket plate 15 and connecting rod 122. The L, N, and E poles on socket plate 15 are electrically connected to retaining plates 1316 on springs 1312 in the three sets of movable and fixed assemblies 131 via electrical wires.

[0052] Reference Figure 2 The cable tray 16 is fixedly connected to the wheel hub 14. Specifically, the cable tray 16 is sleeved on the outside of the wheel hub 14, and the cable tray 16 and the wheel hub 14 can adopt an interference fit.

[0053] Among them, a through hole is opened in the middle position of the cable tray 16, and the fixed shaft 111, the central fixed shaft 12, the power dynamic-fixed conversion structure 13, the hub 14 and the socket plate 15 are all located in the through hole, and the socket plate 15 can be rotatably connected to the cable tray 16.

[0054] Reference Figure 2 and Figure 5 The power cord 17 is wound on the cable tray 16, and the power cord 17 is electrically connected to the power dynamic-static conversion structure 13. Specifically, one end of the power cord 17 is fixedly connected to the dynamic wrapped wire terminal 1318 on the upper plate 1313 in the three groups of dynamic and static components 131, thereby realizing the electrical connection between the power cord 17 and the upper plate 1313. The other end of the power cord 17 is a plug.

[0055] Further, refer to Figure 9 When the cable reel is not in use, the cable reel 16 can be fixed, so an anti-rotation plate 18 is provided on the bracket 11. The anti-rotation plate 18 is clamped on the bracket 11 and can rotate on the bracket 11. An anti-rotation groove 161 for cooperating with the anti-rotation plate 18 is formed on the cable reel 16. By rotating the anti-rotation plate 18 so that it is placed in the anti-rotation groove 161, the cable reel 16 can be prevented from rotating. If the cable reel 16 needs to be rotated, the anti-rotation plate 18 is removed from the anti-rotation groove 161.

[0056] Reference Figure 1 At the same time, in order to facilitate the user to rotate the cable tray 16, a rotating handle 162 is installed on the side end of the cable tray 16, and the user can rotate the cable tray 16 by rotating the handle 162.

[0057] Reference Figure 1 and Figure 9 When the cable reel is not in use or to prevent the power cord 17 from being messy, the power cord 17 can be bound and fixed. A cable clip 19 is fixed on the side end of the cable reel, and the power cord 17 can be clipped into the cable clip 19.

[0058] In order to facilitate the user to transfer the cable reel, an insulating handle 20 is also provided on the top of the bracket 11, wherein the insulating handle 20 can be made of plastic or rubber material. The insulating handle 20 is wrapped on the bracket 11, and anti-slip grooves 201 are distributed on the insulating handle 20 to facilitate the user to grasp the insulating handle 20.

[0059] During use, the power cord 17 can be retracted and released through the cable tray 16. Since the cable tray 16 is fixed to the hub 14, the hub 14 can drive the upper plate 1313 and the bottom plate 1311 to rotate together on the central fixed shaft 12. Since the socket plate 15 is fixedly connected to the central fixed shaft 12, the cable tray 16 can rotate while the socket plate 15 does not rotate. In addition, the rotational connection between the bottom plate 1311 and the upper plate 1313 and the spring piece 1312 is utilized to realize the rotational electrical connection between the power cord 17 and the socket plate 15. Therefore, when the cable tray 16 retracts and releases the power cord 17, it will not affect the normal use of the electrical appliances connected to the socket plate 15.

[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
