Description

Technical Field

[0001] This utility model relates to the field of wire reels, and more specifically, to an anti-rolling wire reel. Background Technology

[0002] Electrical wires are conductors that transmit electrical energy. They are classified into bare wires, magnet wires, and insulated wires. Bare wires have no insulation layer and include copper and aluminum flat wires, overhead stranded wires, and various profiles. They are mainly used in outdoor overhead lines and indoor busbars and switch boxes. Magnet wires are insulated conductors that generate a magnetic field when energized or induce a current in a magnetic field. They are mainly used in motor and transformer windings and other related electromagnetic equipment. Their conductor is primarily copper wire, and they should have a thin insulation layer and good electromechanical properties, as well as heat resistance, moisture resistance, and solvent resistance. Different insulation materials can be used to obtain different properties.

[0003] Before use, electrical wires are usually wound up using a spool to facilitate the unloading process. However, since most conventional spools are round to facilitate transportation and unloading, round spools also have certain drawbacks. For example, they are prone to rolling on uneven surfaces, and larger spools can easily cause safety hazards when rolling. Therefore, we have made an improvement and proposed an anti-rolling electrical wire spool. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-rolling wire reel, which solves the problem that existing anti-rolling wire reels are prone to rolling and causing safety hazards during use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] An anti-rolling wire reel includes a winding post, with rollers fixed at both ends of the winding post. A guide block is fixed on the surface of the roller, and an anti-roll frame is slidably disposed within the guide block. The anti-roll frame can slide along the length direction of the guide block, and a driving structure is provided at the center of the roller.

[0007] The roll cage is connected to the drive structure, and the roll cage can extend beyond the edge of the roller under the action of the drive structure.

[0008] As a preferred technical solution of this application, the anti-roll frame includes a sliding part and an anti-roll part, the sliding part and the anti-roll part are integrally connected, and the sliding part is slidably assembled with the guide block;

[0009] The sliding part is hinged to a drive arm at the end away from the anti-rolling part.

[0010] As a preferred technical solution of this application, the driving structure includes a driving shaft that is movably connected to the center of one side of the roller through a bearing, a driving disk is fixed on the surface of the driving shaft, and the end of the driving arm away from the sliding part is hinged to the surface of the driving disk.

[0011] As a preferred technical solution of this application, a drive handle is fixed to the surface of the drive shaft, and a grip is slidably inserted into the surface of the drive handle.

[0012] As a preferred technical solution of this application, the drive structure further includes a guide sleeve, which is fixed to the surface of the roller and wraps around the edge of the drive disk.

[0013] As a preferred technical solution of this application, a limiting rod is slidably provided inside the guide sleeve, and a spring is fixed on the surface of the limiting rod for fixing it to the side wall of the guide sleeve. One end of the limiting rod extends toward the drive disk and has a common limiting block.

[0014] As a preferred technical solution of this application, a female limiting block adapted to the male limiting block is fixed on the periphery of the drive disk. There are multiple female limiting blocks, and the multiple female limiting blocks are evenly distributed along the circumferential direction of the drive disk.

[0015] As a preferred technical solution of this application, anti-roll convex balls are fixed at both ends of the anti-roll portion, and anti-roll convex ribs are fixed in the middle of the anti-roll portion.

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

[0017] In the scheme of this application:

[0018] 1. With the anti-roll frame in place, when the reel does not need to be rolled for transfer or unloading, multiple drive arms can be swung by the drive structure. During the swaying process, the sliding part slides along the length of the guide block, and the anti-roll part moves to the outer periphery of the reel. This forms a triangular support structure in the circumferential direction of the reel. When the reel rolls, it is supported by the anti-roll part and obstructed, ensuring its safety in its placement state.

[0019] 2. Through the designed drive structure, the anti-roll frame can be reset when the anti-roll mechanism is not needed. This allows multiple anti-roll parts to be housed inside the roller, so that only the roller contacts the base surface, facilitating the rolling effect. Attached Figure Description

[0040] like Figures 1-7 As shown, this embodiment proposes an anti-rolling wire reel, including a winding post 1, with a roller 2 fixed at both ends of the winding post 1. A guide block 21 is fixed on the surface of the roller 2, and an anti-roll frame 22 is slidably provided in the guide block 21. The anti-roll frame 22 can slide along the length direction of the guide block 21, and a driving structure 3 is provided at the center of the roller 2. The anti-roll frame 22 is connected to the driving structure 3, and can be extended beyond the edge of the roller 2 by the action of the driving structure 3.

[0041] The roll cage 22 includes a sliding part 220 and a roll cage 221, which are integrally connected. The sliding part 220 is slidably assembled with the guide block 21. A drive arm 222 is hinged to one end of the sliding part 220 away from the roll cage 221.

[0042] The drive structure 3 includes a drive shaft 31 that is movably connected to the center of one side of the roller 2 via a bearing. A drive disk 32 is fixed on the surface of the drive shaft 31. The end of the drive arm 222 away from the sliding part 220 is hinged to the surface of the drive disk 32.

[0043] A drive handle 310 is fixed to the surface of the drive shaft 31. A handle 311 is slidably inserted into the surface of the drive handle 310. Sliding the handle 311 allows its outer end to be tightly attached to the surface of the drive handle 310 to form a storage effect. Similarly, sliding the handle 311 outward can completely pull it out, increasing the exposed length of the handle 311 and making it easier to grip during rotation.

[0044] The drive structure 3 also includes a guide sleeve 33, which is fixed to the surface of the roller 2 and wraps around the edge of the drive disk 32.

[0045] A limiting rod 330 is slidably provided inside the guide sleeve 33. A spring 331 is fixed to the surface of the limiting rod 330 for fixing it to the side wall of the guide sleeve 33. One end of the limiting rod 330 extends toward the drive disk 32 and has a common limiting block 332. Figure 7 As shown, when supported by the spring 331 in its natural state, the male limit block 332 will abut against the surface of the drive disk 32, thus forming a limiting effect on one side of the drive disk 32.

[0046] The drive disk 32 is fixed with a female limiting block 320 that is adapted to the male limiting block 332. There are multiple female limiting blocks 320, and the multiple female limiting blocks 320 are distributed at equal intervals along the circumferential direction of the drive disk 32.

[0047] Both ends of the anti-roll portion 221 are fixed with anti-roll convex balls 223, and the middle part of the anti-roll portion 221 is fixed with an anti-roll convex rib 224. Through the cooperation of the anti-roll convex balls 223 and the anti-roll convex rib 224, when the anti-roll portion 221 extends outside the roller 2, the anti-roll effect on the spool can be further improved.

[0048] In practical applications, when the reel needs to be prevented from rolling, the drive handle 310 is rotated to drive the drive disc 32 to rotate. During the rotation of the drive disc 32, the multiple drive arms 222 on it swing synchronously. When the drive arms 222 swing, the sliding part 220 can make the anti-roll part 221 on it slide on the outer periphery of the reel 2, thus forming a triangular support structure on the outer periphery of the reel 2, thereby creating an obstacle when the reel rolls, so as to achieve anti-roll.

[0049] During the process of the drive grip 310 driving the drive shaft 31 and its drive disc 32 to rotate, as follows: Figure 7As shown, the counterclockwise rotating drive disk 32 will drive the female limit block 320 on it to rotate synchronously. During the rotation, the male limit block 332 on it will avoid the corresponding female limit block 320 below. When the drive disk 32 finally rotates to the appropriate position, the male limit block 332 will be engaged with the corresponding female limit block 320 on one side due to the force of the spring 331. This prevents the drive disk 32 from rotating clockwise and thus ensures the stability of the roll cage 22 itself. When the drive disk 32 needs to be rotated and reset, the limit rod 330 is pulled upward to compress the spring 331 on it. At the same time, the male limit block 332 at the bottom of the upward-moving limit rod 330 will rise above the female limit block 320. Therefore, the drive disk 32 can be rotated clockwise to reset it and allow multiple roll cages 22 to be stored.

[0050] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
