Description

Technical Field

[0001] This utility model belongs to the field of stage equipment technology, specifically, it relates to a stage cable reel device to prevent cable detachment. Background Technology

[0002] In the field of stage performance, various lighting, sound, and electric props require a large number of wires to ensure normal operation. Before and after the performance, it is essential to collect and organize these wires.

[0003] Traditional stage cable winding methods typically involve simply winding the cables onto a reel or spool. However, this method has several problems. First, due to the lack of effective securing measures, the cables are prone to loosening and coming undone during winding. This not only results in untidy winding but also risks dragging the cables on the ground during transport, causing wear and tear on the cable sheath and shortening the cable's lifespan. Second, traditional winding methods easily lead to the cables becoming tangled and knotted. During frequent performances, cables need to be repeatedly wound up and unwound. If the winding is not organized systematically each time, the cables become increasingly tangled. Once the cables are tangled, a significant amount of time is required to untangle them for the next use. This not only delays performance preparation time but may also damage the cables during untangling, increasing performance costs. Therefore, this utility model is proposed to address these issues. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a stage reel device that can overcome or at least partially solve the above problems and prevent derailment.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a stage take-up device for preventing wire detachment, including a mounting support, and further including: a take-up roller rotatably connected to the mounting support; a crank handle fixedly connected to one end of the take-up roller; the take-up roller is hollow inside, and a through-hole for fixing the end of the wire bundle is opened on the take-up roller; an anti-detachment plate is disposed on the lower side of the take-up roller; and a tensioning telescopic rod is symmetrically fixedly connected to the mounting support, and the telescopic end is fixedly connected to the anti-detachment plate.

[0006] To further reduce friction between the anti-detachment plate and the wire, the anti-detachment plate has multiple rows of movable grooves equidistantly spaced on the side near the take-up roller, and ball bearings are movably connected in the movable grooves.

[0007] To facilitate even winding of the wire onto the take-up roller, a fixed rod is fixedly connected to one side of the mounting bracket. A movable block is slidably connected to the fixed rod, and a rotating plate is rotatably connected to the movable block via a rotating shaft. A semi-circular groove for cooperation is formed on the side of the movable block adjacent to the rotating plate. Multiple rows of rubber brush strips are fixedly connected to the semi-circular grooves of both the movable block and the rotating plate. Threaded grooves are formed on the side of both the movable block and the rotating plate away from the rotating shaft, and connecting bolts are threaded into the threaded grooves. A drive mechanism for driving the movable block to reciprocate on the fixed rod is installed on the mounting bracket.

[0008] Furthermore, the drive mechanism includes a reciprocating screw, a first sprocket, a second sprocket, and a chain. The reciprocating screw is rotatably connected to the mounting bracket near the fixed rod. The moving block is threadedly connected to the reciprocating screw. The first sprocket is fixedly connected to the end of the reciprocating screw near the rotating handle. The second sprocket is fixedly connected to the rotating handle. The chain is sleeved on the first sprocket and the second sprocket.

[0009] To facilitate the movement of the device, a lifting rod is further fixedly connected to the mounting bracket.

[0010] To further improve the comfort of staff when holding the lifting rod, a rubber sleeve is fitted onto the lifting rod.

[0011] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: By using the tensioning telescopic rod and anti-detachment plate in combination, the present invention can not only ensure that the stage wires are wound and stored on the take-up roller in an orderly manner when the stage wires are wound and stored on the take-up roller, but also limit and fix the wires after the take-up is completed, so as to avoid the wires from falling off or getting tangled due to loosening.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] Example 1:

[0020] Reference Figures 1-3 A stage cable take-up device for preventing cable detachment includes a mounting bracket 1, and further includes: a take-up roller 101 rotatably connected to the mounting bracket 1; a crank handle 102 fixedly connected to one end of the take-up roller 101; the take-up roller 101 is hollow inside and has a through-hole 103 for fixing the end of the cable bundle; an anti-detachment plate 201 is disposed on the lower side of the take-up roller 101; and a tensioning telescopic rod 2 is symmetrically fixedly connected to the mounting bracket 1, with its telescopic end fixedly connected to the anti-detachment plate 201.

[0021] The anti-detachment plate 201 has multiple rows of movable grooves equidistantly provided on one side near the take-up roller 101. Ball bearings 202 are movably connected in the movable grooves. When the take-up roller 101 rotates, the wire will come into contact with the ball bearings 202, reducing the friction between the wire and the anti-detachment plate 201 and preventing the anti-detachment plate 201 from causing wear to the wire.

[0022] The anti-detachment plate 201 plays a crucial role in the take-up process. Located below the take-up roller 101, it is connected to the mounting bracket 1 via a tensioning telescopic rod 2. The tensioning telescopic rod 2 adjusts the distance between the anti-detachment plate 201 and the take-up roller 101. During take-up, the anti-detachment plate 201 is close to the take-up roller 101 to prevent the wire from falling off. Due to the presence of the anti-detachment plate 201, the wire is guided systematically onto the take-up roller 101 during take-up. Simultaneously, the anti-detachment plate 201 securely holds the wire on the take-up roller 101, preventing tangling and knotting due to looseness.

[0023] Example 2:

[0024] Reference Figures 1-3A stage cable reel device for preventing cable detachment is basically the same as in Embodiment 1, but with the following additional features: a fixed rod 3 is fixedly connected to one side of the mounting bracket 1, a movable block 301 is slidably connected to the fixed rod 3, and a rotating plate 302 is rotatably connected to the movable block 301 via a rotating shaft. A semi-circular groove for cooperation is opened on the side of the movable block 301 adjacent to the rotating plate 302. Multiple rows of rubber brush strips 304 are fixedly connected in the semi-circular grooves of both the movable block 301 and the rotating plate 302. A threaded groove is opened on the side of the movable block 301 and the rotating plate 302 away from the rotating shaft, and a connecting bolt 303 is threadedly connected in the threaded groove. A drive mechanism for driving the movable block 301 to reciprocate on the fixed rod 3 is installed on the mounting bracket 1.

[0025] The drive mechanism includes a reciprocating screw 4, a first sprocket 401, a second sprocket 402, and a chain 403. The reciprocating screw 4 is rotatably connected to the mounting bracket 1 near the fixed rod 3. The moving block 301 is threadedly connected to the reciprocating screw 4. The first sprocket 401 is fixedly connected to one end of the reciprocating screw 4 near the rotating handle 102. The second sprocket 402 is fixedly connected to the rotating handle 102. The chain 403 is sleeved on the first sprocket 401 and the second sprocket 402.

[0026] When stage wiring harnesses need to be stored, the operator first places one end of the harness onto the take-up roller 101 through the through-hole 103, and then places the harness into the semi-circular groove on the movable block 301. Next, the rotating plate 302 and the movable block 301 are fixed together using connecting bolts 303, thus confining the harness within the two semi-circular grooves. When the operator rotates the take-up roller 101 by turning the crank 102, the crank 102 will then pass through the first sprocket 401... The second sprocket 402 and chain 403 drive the reciprocating screw 4 to rotate. The reciprocating screw 4 then drives the moving block 301 to move back and forth on the fixed rod 3. This ensures that the wire harness is evenly wound on the take-up roller 101 when it is wound around the take-up roller 101. At the same time, the rubber brush strip 304 set in the semi-circular groove removes small particles of debris adhering to the surface of the wire harness, preventing damage to the protective sheath of the wire harness after it is tangled together, thus effectively ensuring the service life of the wire harness.

[0027] Example 3:

[0028] Reference Figures 1-3 A stage cable reel device for preventing cable detachment is basically the same as in Embodiment 2, but with the following additional feature: a lifting rod 104 is fixedly connected to the mounting bracket 1. The lifting rod 104 facilitates the movement and transportation of the device by the staff, making it more convenient for the staff to use the device.

[0029] A rubber sleeve 105 is fitted onto the lifting rod 104. The rubber sleeve 105 makes it more comfortable for staff to hold the lifting rod 104.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
