Description

Technical Field

[0001] This utility model relates to a cable support device, specifically an adjustable cable support device for electrical engineering, belonging to the field of electrical engineering cable technology. Background Technology

[0002] Electrical engineering is defined as the discipline that creates electrical and electronic systems. Today, electrical engineering encompasses almost all engineering activities related to electronics and photonics. A large number of cables are used in electrical engineering, and support devices are often used during the use of cables.

[0003] According to the utility model patent application CN215934349U, a cable support device for electrical engineering is disclosed, which includes a fixing plate and a limiting plate. The left side of the inner side of the fixing plate is fixedly connected to the outer side of the limiting plate, and a sliding groove is provided on the right side of the limiting plate.

[0004] Although the swaying force generated by the cable can cause breakage or damage at the connection between the cable and the support device, the device lacks the function of adjusting cable tension. As a result, after the cable is installed, it is easy for the cable to be too tight or too loose, requiring adjustment of the entire cable. This increases the complexity of the operation for workers and reduces the practicality of the cable support device.

[0005] Therefore, an adjustable cable support device for electrical engineering is proposed here. Utility Model Content

[0006] This utility model proposes an adjustable cable support device for electrical engineering to solve the problem that existing cable support devices do not have the function of adjusting cable tension.

[0007] This utility model is achieved through the following technical solution: an adjustable cable support device for electrical engineering, including a frame, wherein an adjustment mechanism is provided inside the frame;

[0008] The adjustment mechanism includes two placement frames, each with both ends fixedly connected to the inner wall of the frame. Two sets of connecting springs are fixedly installed on the inner wall of each placement frame. A pulley is fixedly installed at the end of each connecting spring furthest from the placement frame. A ball screw is rotatably connected inside the frame. A movable plate is threaded onto the outer surface of the ball screw. Two fixing springs are fixedly installed on the upper surface of the movable plate. A mounting plate is fixedly installed at the top ends of the two fixing springs. A fixing frame is fixedly installed on the upper surface of the mounting plate. A roller is rotatably connected inside the fixing frame. A scale is fixedly installed on the bottom surface of the mounting plate. A locking assembly is located above the frame.

[0009] The locking assembly includes a turntable, the bottom surface of which is fixedly connected to the top end of a ball screw. Two limit springs are fixedly installed on the upper surface of the frame, and a connecting post is fixedly installed on the top end of each limit spring. Each connecting post is engaged inside the turntable.

[0010] Two sets of telescopic rods are fixedly installed on the inner wall of the placement rack, and the telescopic end of each telescopic rod is fixedly connected to the side of the pulley near the placement rack.

[0011] A slide bar is fixedly installed on the inner wall of the frame, and the outer surface of the slide bar is fixedly connected to the inner wall of the moving plate.

[0012] Two telescopic columns are fixedly installed on the upper surface of the movable plate, and the telescopic end of each telescopic column is fixedly connected to the bottom surface of the mounting plate.

[0013] Each of the connecting columns is fixedly equipped with a telescopic shaft at its bottom end, and the bottom end of each telescopic shaft is fixedly connected to the upper surface of the frame.

[0014] This utility model provides an adjustable cable support device for electrical engineering, which has the following advantages: This adjustable cable support device for electrical engineering includes a mounting frame, connecting spring, pulley, ball screw, moving plate, fixed spring, mounting plate, fixed frame, and roller. The connecting spring's elasticity causes the pulley to clamp and limit the cable. Simultaneously, the worker rotates the ball screw, causing it to move the moving plate up and down, thus adjusting the cable tension. This eliminates the need for manual adjustment of the entire cable, increasing the device's practicality. A scale is included, with the fixed spring's elasticity and the scale extending beyond the moving plate, allowing the worker to easily understand the cable tension and adjust it as needed. A locking component locks the ball screw, preventing it from rotating on its own during cable support and thus preventing the device's tension from adjusting automatically.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0025] Please see Figure 1 and Figure 2 This utility model provides an adjustable cable support device for electrical engineering, including a frame 1. An adjustment mechanism 2 is installed inside the frame 1. The adjustment mechanism 2 includes two placement frames 201, each with both ends fixedly connected to the inner wall of the frame 1. Two sets of connecting springs 202 are fixedly installed on the inner wall of each placement frame 201. A pulley 203 is fixedly installed on the end of each connecting spring 202 away from the placement frame 201. The pulley 203 clamps the cable from four positions using the elastic force of the connecting springs 202, thus supporting and limiting the cable. Two sets of telescopic rods 3 are fixedly installed on the inner wall of the placement frame 201. The telescopic end of each telescopic rod 3 is fixedly connected to the side of the pulley 203 near the placement frame 201. The installation of the telescopic rods 3 restricts the movement trajectory of the pulley 203, preventing it from deviating from its movement trajectory and ensuring the stability of the pulley 203's movement.

[0026] Please refer to this carefully. Figure 1 The frame 1 is internally connected to a ball screw 204, and the outer surface of the ball screw 204 is threaded to a movable plate 205. A slide rod 4 is fixedly installed on the inner wall of the frame 1, and the outer surface of the slide rod 4 is fixedly connected to the inner wall of the movable plate 205. The installation of the slide rod 4 restricts the movement trajectory of the movable plate 205, thereby preventing the movable plate 205 from rotating during movement and ensuring the stability of the movement of the movable plate 205.

[0027] Please refer to this carefully. Figure 1 and Figure 3 Two fixing springs 206 are fixedly installed on the upper surface of the movable plate 205. The top ends of the two fixing springs 206 are fixedly installed on the mounting plate 207. Two telescopic columns 5 are fixedly installed on the upper surface of the movable plate 205. The telescopic end of each telescopic column 5 is fixedly connected to the bottom surface of the mounting plate 207. The installation of the telescopic columns 5 plays a role in restricting the movement trajectory of the mounting plate 207, thereby ensuring the stability of the movement of the mounting plate 207.

[0028] Please refer to this carefully. Figure 1 , Figure 3 and Figure 4 A mounting bracket 208 is fixedly mounted on the upper surface of the mounting plate 207. A roller 209 is rotatably connected inside the mounting bracket 208. A scale 210 is fixedly mounted on the bottom surface of the mounting plate 207. A fixing spring 206 cooperates with the scale 210. When the cable is subjected to tension, the fixing spring 206 is compressed, causing the scale 210 to extend out of the moving plate 205. The tension of the cable is determined by the distance the scale 210 extends out of the moving plate 205. A locking assembly 211 is provided above the frame 1. The locking assembly 211 includes a turntable 2111. The bottom surface of frame 1 is fixedly connected to the top of ball screw 204. Two limit springs 2112 are fixedly installed on the upper surface of frame 1. Each limit spring 2112 has a connecting post 2113 fixedly installed at its top. Each connecting post 2113 is engaged inside turntable 2111. The outer surface of turntable 2111 has through holes arranged at equal intervals. The elastic force of the limit springs 2112 makes the connecting post 2113 engage inside turntable 2111, thereby locking ball screw 204 and preventing ball screw 204 from rotating on its own, thus ensuring the stability of ball screw 204.

[0029] Please refer to this carefully. Figure 4 Each connecting column 2113 has a telescopic shaft 6 fixedly installed at its bottom end. The bottom end of each telescopic shaft 6 is fixedly connected to the upper surface of the frame 1. The installation of the telescopic shaft 6 restricts the movement trajectory of the connecting column 2113, thereby preventing the connecting column 2113 from deviating from its movement trajectory and ensuring the stability of the connecting column 2113.

[0030] In use, the worker first passes the cable through the inside of the pulley 203 and above the roller 209, so that the cable is sleeved on the outer surface of the roller 209. Simultaneously, the elastic force of the connecting spring 202 causes the pulley 203 to clamp and limit the cable. Then, the worker pulls the connecting column 2113 downwards, causing it to slide off the turntable 2111. Next, the worker rotates the turntable 2111, causing the ball screw 204 to rotate. This causes the ball screw 204 to move the moving plate 205 upwards, which in turn moves the cable upwards. Thus, the cable passes through the pulley 203. Under the action of 03 and roller 209, the cable forms an arch shape. During this process, the cable squeezes the roller 209, which in turn compresses the fixed spring 206, causing the scale 210 to move downward. The cable tension is determined by the length of the scale 210 extending out of the moving plate 205. Afterward, the worker loosens the connecting post 2113, which is then locked inside the turntable 2111 by the elastic force of the limit spring 2112, thereby locking the ball screw 204 and preventing the cable tension from adjusting itself. This allows the worker to adjust the cable tension as needed without having to adjust the entire cable.
