Description

Technical Field

[0001] The present application relates to a cable reel. Background Art

[0002] When the manual cable reel is pulling out the cable quickly, due to inertia, the turntable will continue to rotate quickly for a period of time after the pulling stops. At this time, the cable on the turntable will spread out inside the cable reel due to the centrifugal force. The scattered cables will randomly overlap, causing the overlapping cables to entangle with each other when the cable is pulled out again, resulting in the cable being stuck and unable to be pulled out.

[0003] In one possible solution, a gasket is provided between the rotating disk and the fixed shaft of the reel, and the gasket is fixed and pressed. When the rotating disk rotates, the gasket and the rotating disk generate friction, thereby forming a damping force so that the rotating disk can rotate slowly. However, due to factors such as size and assembly tolerance, the corresponding friction force is difficult to control, resulting in the rotating disk not rotating smoothly or the damping being too small.

[0033] In order to more clearly explain the above-mentioned purposes, features and advantages of the present application, the specific implementation methods of the present application are described in detail in this section in conjunction with the accompanying drawings. In addition to the various implementation methods described in this section, the present application can also be implemented in other different ways. Without violating the spirit of the present application, those skilled in the art can make corresponding improvements, deformations and substitutions, so the present application is not limited by the specific embodiments disclosed in this section. The scope of protection of the present application shall be subject to the claims.

[0034] In the following description, unless otherwise specified, the axial direction A refers to the axial direction of the cable reel, the circumferential direction C refers to the circumferential direction of the cable reel, and the radial direction R refers to the radial direction of the cable reel.

[0035] like Figures 1 to 4As shown, the embodiment of the present application provides a cable reel, which includes a chassis 1, a turntable 2, a damping structure 3 and a rolling body 4. The cable reel can be used to wind and store wires. For example, the cable reel can be used for electrical appliances with long power cords that need to be moved frequently, such as vacuum cleaners, high-pressure cleaners, etc. However, the present application is not limited thereto, and the cable reel of the embodiment of the present application can also be used for other devices or other types of cables.

[0036] The chassis 1 may include a bottom wall portion 11 and a peripheral wall portion 12. The bottom wall portion 11 may include a (roughly) flat plate-like structure extending along the circumferential direction C and radial direction R of the reel. The peripheral wall portion 12 may include a cylindrical structure extending along the circumferential direction C and axial direction A of the reel. The peripheral wall portion 12 may be connected to the outer periphery of the bottom wall portion 11.

[0037] The bottom wall 11 of the chassis 1 may be provided with a mounting post 13, which may be located at the center of the chassis 1. The mounting post 13 may extend along the axial direction A of the chassis 1, and the mounting post 13 extends from the bottom wall 11 to the same side as the peripheral wall 12.

[0038] like Figures 1 to 3 As shown, the turntable 2 can be rotatably connected to the chassis 1 relative to the chassis 1, and the turntable 2 can be sleeved on the mounting post 13, and the turntable 2 can rotate around the mounting post 13. The cable can be connected to the turntable 2, and as the turntable 2 rotates, the cable can be wound and stored in the turntable 2 or released from the turntable 2. The damping structure 3 is installed between the chassis 1 and the turntable 2, and when the turntable 2 rotates relative to the chassis 1, the damping structure 3 can stably provide friction.

[0039] The mounting column 13 may include a large diameter portion 131 and a small diameter portion 132. The large diameter portion 131 may be connected to the bottom wall portion 11 of the chassis 1, and the small diameter portion 132 may be connected to the large diameter portion 131. The diameter of the small diameter portion 132 is smaller than the diameter of the large diameter portion 131, and a step surface 133 may be provided between the large diameter portion 131 and the small diameter portion 132.

[0040] like Figures 2 to 4 As shown, the damping structure 3 includes a bolt 31 , a washer 32 , a bushing 33 and a spring 34 .

[0041] The spring 34 can be sleeved on the small diameter portion 132 of the mounting column 13, and the spring 34 can be a compression coil spring. Figure 2 The lower end of the large diameter portion 131 can abut against the step surface 133 between the large diameter portion 131 and the small diameter portion 132.

[0042] The bushing 33 includes a bushing end wall 331 and a bushing peripheral wall 332. The bushing end wall 331 may be annular, and the bushing peripheral wall 332 may be cylindrical. In the axial direction A of the reel, the bushing end wall 331 separates the spring 34 from the rotating disk 2, thereby preventing the rotating disk 2 from being worn. The bushing 33 can cover the spring 34. The other end ( Figure 2 The upper end of the spring 34 can abut against the bushing end wall 331 to separate the spring 34 from the turntable 2, and the bushing peripheral wall 332 can surround the radial outer side of the spring 34.

[0043] The bushing 33 can fix the spring 34 and prevent the spring 34 from being worn due to friction with the turntable 2 .

[0044] like Figure 3 and Figure 4 As shown, the axial end of the bushing peripheral wall 332 can be provided with a concave-convex tooth structure 333, and the step surface 133 of the mounting column 13 can be provided with a groove that cooperates with the tooth structure 333, so that the bushing 33 is positioned in the circumferential direction C and the bushing 33 cannot rotate relative to the chassis 1.

[0045] The turntable 2 can be sleeved on the bushing 33 . The outer peripheral surface and the top surface of the bushing 33 are smooth and flat. The bushing 33 plays a role similar to a bearing, reducing the wear between the mounting column 13 and the turntable 2 .

[0046] The mounting column 13 may be provided with a threaded hole, and the bolt 31 may pass through the turntable 2 and be screwed into the threaded hole of the mounting column 13, so that the turntable 2 is mounted on the chassis 1. The gasket 32 ​​may be sleeved on the bolt 31, and the gasket 32 ​​may be located between the head of the bolt 31 and the turntable 2. Tightening the bolt 31 may compress the spring 34, so that the gasket 32 ​​presses the turntable 2 and the turntable 2 is mounted on the mounting column 13. When the turntable 2 rotates, there are two positions in the damping structure 3 that can provide friction, one is that the bushing 33 and the turntable 2 can generate sliding friction, and the other is that the gasket 32 ​​and the head of the bolt 31 can generate sliding friction.

[0047] Furthermore, under the support of the spring 34, an axial gap may be left between the toothed structure 333 of the bushing 33 and the groove of the step surface 133, allowing the bushing 33 to move along the axial direction A. By rotating the bolt 31 to move the bushing 33 along the axial direction A, the degree of compression of the spring 34 can be adjusted. Within the adjustment stroke, the bushing 33 can move along the axial direction A of the reel, and the toothed structure 333 and the step surface 133 remain in an engaged state.

[0048] It can be understood that the compression amount of the spring 34 is easy to control. By accurately controlling the compression of the spring, the pressure on the turntable 2 can be stabilized and the consistency is good, and then the friction force of the turntable rotation is also easy to control, so that the damping of the turntable rotation is appropriate. After the turntable 2 is rotated by quickly pulling the cable, the turntable 2 can stop quickly, reducing the probability of wire explosion and wire jam.

[0049] The rolling body 4 can be rotatably connected to the bottom wall portion 11 of the chassis 1. The rolling body 4 can include a cylindrical structure. The axis of the rolling body 4 can extend along the radial direction of the reel. Multiple rolling bodies 4 can be arranged along the circumferential direction C of the reel. The rolling body 4 can be used to support the turntable 2 so that the turntable 2 can rotate smoothly.
