Description

Technical Field

[0001] This utility model relates to the field of roller technology, and in particular to a cable winding expansion and contraction roller. Background Technology

[0002] An expansion and contraction roller is a roller device whose size can be adjusted as needed. Expansion and contraction rollers may serve different purposes in different types of equipment.

[0003] Chinese Patent No. CN221876184U discloses an expansion and contraction roller, including a main shaft and several expansion and contraction mechanisms. Each mechanism includes an arc-shaped top plate and a telescopic structure. A guide groove is provided on the main shaft, the arc-shaped top plate is mounted on the guide groove, and a return spring is installed within the guide groove. This invention, by arranging multiple expansion and contraction mechanisms that can move up and down along the guide groove around the outside of the main shaft, makes the disassembly of printed labels more convenient and faster. Simultaneously, during normal winding, the arc-shaped top plate can be reset by the return spring, reducing the frequency of use of the telescopic structure and improving the roller's service life. In summary, this technical solution has the advantages of simple structure, ease of use, and strong practicality, and is suitable for the winding of various printed labels.

[0004] However, the above technology has the following shortcomings: when shrinking the diameter of the main shaft through the telescopic structure, it is necessary to reduce the diameter formed by the cooperation of multiple arc top plates by pressing it from both ends of the arc top plate, and the method of adjusting the diameter in the referenced document is rather cumbersome. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a cable winding expansion and contraction roller that reduces the difficulty of adjusting the distance between multiple arc-shaped top plates by driving a control board to rotate, which in turn drives a bidirectional lead screw to rotate, and the bidirectional lead screw to drive two directional rings to rotate relative to each other or in opposite directions, thereby allowing the directional rings to move the arc-shaped top plate.

[0006] The technical solution of this utility model is a cable winding expansion and contraction roller, comprising: two mounting plates arranged side by side, with multiple connecting plates distributed in a ring on the two mounting plates; an adjustment assembly including a bearing on each of the two mounting plates, a bidirectional lead screw mounted on the two bearings, a control plate on each end of the bidirectional lead screw, two directional rings threadedly connected to the bidirectional lead screw, multiple push plates rotatably connected to each of the two directional rings in a ring, and multiple arc-shaped top plates distributed in a ring; the multiple arc-shaped top plates are rotatably connected to multiple pairs of push plates one-to-one; and a connecting member, one on each of the two mounting plates.

[0007] Preferably, both mounting plates are provided with toothed rings.

[0008] Preferably, the thickness of the toothed ring is greater than the thickness of the control plate.

[0009] Preferably, both control panels have grooves distributed in a ring shape.

[0010] Preferably, an intermediate bearing is provided between the control board and the mounting plate.

[0011] Preferably, the directional ring includes a movable ring portion threadedly connected to a bidirectional lead screw, and a plurality of mounting bracket portions arranged circumferentially on the movable ring portion; the mounting bracket portions slide in contact with the connecting plate.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] When this utility model is used, according to the required inner diameter of the cable reel, the control board drives the bidirectional screw to rotate. The bidirectional screw thread drives the two adjusting rings to move relative to each other or in opposite directions. During the movement of the adjusting rings, the push plate rotates. The push plate drives the arc top plate to adjust its position, thereby adjusting the diameter formed by the arc top plate. The adjustment can be made through a single control board, reducing the difficulty of adjusting the diameter of the roller. Attached Figure Description

[0019] Example 1

[0020] like Figures 1-4As shown, this embodiment proposes a cable winding expansion and contraction roller, including a mounting plate, an adjustment assembly, and a connector 3: two mounting plates 1 are arranged side by side, and multiple connecting plates 12 distributed in a ring are provided on the two mounting plates 1; the adjustment assembly includes a bearing 11 provided on each of the two mounting plates 1, a bidirectional lead screw 4 provided on the two bearings 11, a control plate 2 provided at each end of the bidirectional lead screw 4, two directional rings 5 ​​threadedly connected to each other on the bidirectional lead screw 4, multiple push plates 6 rotatably connected to each of the two directional rings 5 ​​in a ring, and multiple arc-shaped top plates 7 distributed in a ring; the connector 3 can be a mounting column or a groove, so that the roller can be suspended in the air by means of a coupling or other object.

[0021] Multiple arc-shaped top plates 7 are rotatably connected to multiple pairs of push plates 6 in a one-to-one correspondence; one connector 3 is set on each of the two mounting plates 1, the push plates 6 on the two directional rings 5 ​​are in the same position, and the push plates 6 in the same position on the two directional rings 5 ​​are a pair.

[0022] In this embodiment, according to the required inner diameter of the cable reel, the control plate 2 drives the bidirectional screw 4 to rotate. The bidirectional screw 4 drives the two adjusting rings 5 ​​to move relative to each other or in opposite directions. During the movement of the adjusting rings 5, the push plate 6 rotates. The push plate 6 drives the arc top plate 7 to adjust its position, thereby adjusting the diameter formed by the arc top plate 7. The adjustment can be made by a single control plate 2, reducing the difficulty of adjusting the diameter of the roller.

[0023] Example 2

[0024] like Figures 1-3 As shown in the figure, the cable winding expansion and contraction roller proposed in this embodiment, compared with the first embodiment, has toothed rings 8 on both mounting plates 1. If the roller needs to be driven by an external drive component, the drive component drives the toothed rings 8 to rotate through gear meshing, so that the roller can automatically wind and unwind. The thickness of the toothed rings 8 is greater than the thickness of the control plate 2, so that the control plate 2 installed on the mounting plate 1 will extend a certain length beyond the toothed rings 8, allowing the user to easily pinch the control plate 2 and improve the portability of adjusting the roller diameter.

[0025] Both control plates 2 have grooves 10 distributed in a ring shape. These grooves 10 provide users with a gripping space, allowing for some adjustment of the control plates 2 even in confined spaces. An intermediate bearing 9 is provided between the control plate 2 and the mounting plate 1. When the control plate 2 drives the bidirectional lead screw 4 to rotate, the intermediate bearing 9 can improve the smoothness of the rotation of the control plate 2 and reduce the force required to rotate the control plate 2.

[0026] Example 3

[0027] like Figure 4As shown, in this embodiment, a cable winding expansion and contraction roller is proposed. Compared with the first embodiment, in this embodiment, the directional ring 5 includes a movable ring portion 51 threadedly connected to the bidirectional lead screw 4, and a plurality of mounting bracket portions 52 arranged in a ring on the movable ring portion 51; the mounting bracket portions 52 are in sliding contact with the connecting plate 12.

[0028] In this embodiment, the bidirectional lead screw 4 drives the moving ring 51 to rotate. The moving ring 51 drives the push plate 6 to rotate through the mounting frame 52. The distance between the multiple arc-shaped top plates 7 is adjusted by adjusting the inclination of the push plate 6. The two push plates 6 and the arc-shaped top plates 7 are arranged in a trapezoidal shape, thereby improving the structural strength of the arc-shaped top plates 7. The mounting frame 52 will abut against the connecting plate 12, so that when the connecting plate 12 rotates, it will drive the mounting frame 52 to rotate synchronously, improving the practicality of the roller.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
