Description

Technical Field

[0001] This utility model relates to the field of communication cable winding and unwinding technology, and specifically to a communication cable winding and unwinding device that can fix the cable. Background Technology

[0002] A cable winding and unwinding device for securing cables is a specialized piece of equipment used in communication engineering for cable laying, retrieval, and storage. It typically includes a reel for winding the cable, a frame that supports the reel and allows it to rotate, a power system that drives the reel to rotate forward and backward, and a key cable securing mechanism. The securing mechanism is usually located on the flange of the reel, and its function is to firmly clamp the cable end onto the reel at the beginning of cable winding and to prevent the cable from completely detaching from the reel at the end of unwinding, ensuring safe and efficient operation. The process is mainly divided into two stages: cable winding and cable unwinding. When winding the cable, the operator first passes the end of the cable through the guide device and locks it on the reel using the cable fixing mechanism. Then, the power system is started, the reel rotates, and the loose or retrievable cables are neatly wound onto the reel. When unwinding the cable, the process is reversed. The cable is pulled out from the rotating reel by mechanical equipment and laid to the designated location. However, the take-up drum in the take-up and unwinding device is connected by bolts, and there is no auxiliary structure during installation. Both ends of the take-up drum need to be supported. When the hand slips, the take-up drum is difficult to connect accurately, which reduces the flexibility of the take-up and unwinding device. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a communication cable winding and unwinding device that can fix the cable, which can effectively solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a communication cable winding and unwinding device for fixing cables, including a winding and unwinding frame, a motor fixedly connected to the right side of the winding and unwinding frame, a rotating shaft connected to one end of the motor, a winding drum inside the winding and unwinding frame, a connecting plate fixedly connected to the front of the winding and unwinding frame, an auxiliary structure on the front of the connecting plate, a fixing post connected inside the winding drum, a collar fixedly connected to the outside of the fixing post, a positioning groove inside the winding and unwinding frame, a sliding groove inside the fixing post, a driving structure inside the fixing post, a circular groove at one end of the winding drum, a fixing structure inside the circular groove, the auxiliary structure including a screw and a limiting plate, a nut threadedly connected to the external thread of the screw, a limiting groove outside the limiting plate, and a driving structure including a moving ring, a connecting rod, and a cross plate, a bolt inside the moving ring, and a spring on one side of the moving ring.

[0005] Furthermore, the collar is engaged in the positioning groove, the fixing post is rotatably connected in the take-up and put-down frame, and the screw is fixedly connected to the front of the connecting plate.

[0006] Furthermore, the screw is engaged in the screw rod, and the screw rod is connected to the limiting plate through the nut. The limiting plate is engaged in the take-up and take-down frame.

[0007] Furthermore, the connecting rod is slidably connected to the fixed column, the cross plate is snapped into the rotating shaft, the moving ring is slidably connected to the slide groove, and the moving ring is connected to the fixed column by a spring.

[0008] Furthermore, the fixing structure includes a sliding block, which is rotatably connected in a circular groove, and an L-shaped plate is fixedly connected above the sliding block.

[0009] Furthermore, the L-shaped plate is internally threaded with a threaded rod, the bottom end of which is connected to a suction cup, and the top end of which is fixedly connected to a turntable.

[0010] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. By setting up a take-up drum, a collar, a positioning groove, an auxiliary structure, and a connecting plate, the take-up drum can slide within the positioning groove via the collar. When the take-up drum is fully attached to the take-up and unwinding frame, the limiting plate is engaged with the take-up and unwinding frame. The limiting groove on the surface of the limiting plate will move within the positioning groove. After moving, the limiting plate will contact the collar, and the screw will penetrate the limiting plate. The screw locks the limiting plate with a nut, achieving initial centering and positioning. This greatly simplifies the installation process and effectively avoids the trouble of having to support the take-up drum with both hands in traditional installation. Even if the hands slip during operation, the connection can be completed quickly and accurately, significantly improving the flexibility and installation efficiency of the take-up and unwinding device.

[0011] 2. By setting up a fixed structure, the communication cable is stored using a winding drum. When storage is complete, the sliding block rotates on the surface of the circular groove. When the moving ring moves to the appropriate position, the turntable drives the threaded rod to rotate. After the threaded rod rotates, the suction cup at the bottom of the threaded rod will fix the communication cable. The suction cup uses adsorption force to firmly fix the cable end, preventing the cable from falling off due to loosening during transportation or storage. It is not only reliable in fixing, but also easy to operate, improving the safety and convenience of winding and unwinding operations. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the embodiments. Example 1:

[0017] Reference Figure 1-4This is the first embodiment of the present invention, which discloses a communication cable winding and unwinding device for fixing cables. It includes a winding and unwinding frame 1, a motor 2 fixedly connected to the right side of the frame 1, a rotating shaft 3 connected to one end of the motor 2, a winding drum 4 inside the frame 1, a connecting plate 5 fixedly connected to the front of the frame 1, an auxiliary structure 6 on the front of the connecting plate 5, a fixing post 11 connected inside the winding drum 4, a collar 9 fixedly connected to the outside of the fixing post 11, a positioning groove 10 inside the frame 1, and a positioning groove 10 inside the fixing post 11. The device has a sliding groove 12, a drive structure 7 inside the fixed column 11, a circular groove 13 at one end of the winding drum 4, a fixed structure 8 inside the circular groove 13, an auxiliary structure 6 including a screw 601 and a limiting plate 602, a nut 603 connected to the external thread of the screw 601, a limiting groove 604 outside the limiting plate 602, a moving ring 701, a connecting rod 702 and a cross plate 703, a bolt 704 inside the moving ring 701, and a spring 705 on one side of the moving ring 701.

[0018] The collar 9 is engaged in the positioning groove 10, the fixed column 11 is rotatably connected in the take-up and take-down frame 1, the screw 601 is fixedly connected to the front of the connecting plate 5, the screw 601 is engaged in the screw 601, the screw 601 is connected to the limiting plate 602 through the nut 603, the limiting plate 602 is engaged in the take-up and take-down frame 1, the connecting rod 702 is slidably connected in the fixed column 11, the cross plate 703 is engaged in the rotating shaft 3, the moving ring 701 is slidably connected in the slide groove 12, and the moving ring 701 is connected in the fixed column 11 through the spring 705.

[0019] By setting up the drive structure 7, a fast and stable connection between the winding drum 4 and the motor 2 shaft 3 is achieved. Utilizing the elastic restoring force of the spring 705, the moving ring 701 can adaptively adjust its position, effectively compensating for possible axial dimensional deviations during assembly and ensuring smooth connection. The cross plate 703 and the shaft 3 adopt a non-circular cross-section snap-fit ​​design, forming a reliable torque transmission path, avoiding slippage and ensuring high efficiency of power transmission. At the same time, the moving ring 701 is locked to the fixed column 11 by bolts 704, further enhancing the integrity and rigidity of the connection, preventing loosening or abnormal noise during winding, thereby ensuring a smooth winding process. Example 2:

[0020] Reference Figure 4 This is the second embodiment of the present invention, which differs from the first embodiment in that: The fixed structure 8 includes a sliding block 801, which is rotatably connected in the circular groove 13. An L-shaped plate 802 is fixedly connected above the sliding block 801. A threaded rod 803 is threadedly connected inside the L-shaped plate 802. A suction cup 805 is connected to the bottom end of the threaded rod 803. A turntable 804 is fixedly connected to the top end of the threaded rod 803.

[0021] By setting the fixing structure 8, the cable end is quickly and reliably fixed and conveniently released. The sliding block 801 design allows the L-shaped plate 802 to rotate flexibly around the axis of the winding drum 4, easily covering different positions where the cable end may appear. The height of the suction cup 805 can be accurately and effortlessly adjusted by rotating the turntable 804, so that it can effectively adapt to cables of different diameters and tension states. After the suction cup 805 contacts the cable surface, it generates adsorption force and pressure, which work together to form a firm fixing effect without damaging the cable sheath.

[0022] The remaining structure is the same as that in Example 1.

[0023] The workflow of this utility model is as follows: When the communication cable winding device winds up the communication cable, the winding drum 4 can slide within the positioning groove 10 via the collar 9. When the winding drum 4 is fully engaged with the winding frame 1, the limiting plate 602 is engaged with the winding frame 1. The limiting groove 604 on the surface of the limiting plate 602 will move within the positioning groove 10. After moving, the limiting plate 602 will contact the collar 9, and the screw 601 will insert into the limiting plate 602. The screw 601 locks the limiting plate 602 with the nut 603, subsequently driving the moving ring 701 to slide within the fixed post 11, forming a cross shape. The plate 703 moves with the moving ring 701 via the connecting rod 702. After moving, the cross plate 703 is engaged in the rotating shaft 3, and the spring 705 deforms accordingly. The moving ring 701 is then connected to the surface of the fixed column 11 via the bolt 704. Subsequently, the communication cable is wound up by the winding drum 4. When the winding is completed, the sliding block 801 rotates on the surface of the circular groove 13. When the moving ring 701 moves to the appropriate position, the turntable 804 drives the threaded rod 803 to rotate. After the threaded rod 803 rotates, the suction cup 805 at the bottom of the threaded rod 803 fixes the communication cable.

[0024] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
