[0002] With the continuous improvement of technology and the widespread application of electrical equipment, electricity has become an indispensable energy source in modern society. Therefore, cables used to transmit electrical energy play a crucial role in daily life and industrial production. During cable laying, cable laying racks, as auxiliary tools, are of great significance in ensuring the quality and efficiency of cable laying.

[0003] Currently, common cable laying racks are mainly composed of trays or ladders, accessories, supports, hangers, and other components. Tray-type cable trays consist of a base plate and side plates, which are used to directly support the cable load. Ladder-type cable trays consist of side plates and several crossbars, forming a trapezoidal component with a certain rigidity.

[0004] Traditional cable laying racks mostly use an integrated design structure for fixing, which makes it difficult to quickly adjust the height according to the actual needs of the cable. They are also inconvenient to transport and have poor fastening effect when placing cables, which may cause the cables to slip or fall off during the laying process, thus affecting the laying quality and safety. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a height-adjustable cable laying rack, which aims to improve the problem that traditional cable laying racks are difficult to quickly adjust in height according to actual needs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a height-adjustable cable laying rack, including a base, wherein an adjustment component is provided inside the base;

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

[0025] Reference Figures 1-4 One embodiment of this utility model is a height-adjustable cable laying rack, including a base 5, and an adjustment component is provided inside the base 5;

[0026] The adjustment assembly includes a support rod 1, one end of which is rotatably connected to a base 5, which supports the entire device. A rotating shaft 2 is rotatably connected inside the support rod 1. A fixing block 8 is fixedly connected to the middle of the rotating shaft 2, which is used to cooperate with the movement of a threaded rod 7. The threaded rod 7 is threadedly connected inside the fixing block 8. A support rod 4 is rotatably connected to the outer wall of the rotating shaft 2. A bracket 6 is rotatably connected to one end of the support rod 4, which supports the cable. A support rod 14 is rotatably connected to one side of the outer wall of the bracket 6. A rotating shaft 2 is rotatably connected to one end of the support rod 14. A fixing block 9 is fixedly connected to the middle of the rotating shaft 2. A support rod 15 is rotatably connected to the outer wall of the rotating shaft 2. One end of the support rod 15 is rotatably connected to the other side of the inner wall of the base 5. A limit component is provided on the upper surface of the bracket 6.

[0027] Specifically, support rod 1 is rotatably connected to base 5 and can rotate around base 5. Rotating shaft 2 is rotatably connected inside support rod 1 and is threadedly connected to fixing block 8 via threaded rod 7. When threaded rod 7 rotates, it pulls fixing block 8 and rotating shaft 2 to move along support rod 1, thereby changing the angle between support rod 2 4 and support rod 1, and realizing height adjustment. Support rod 2 4 is rotatably connected to the outer wall of rotating shaft 2, and the other end is rotatably connected to bracket 6, so that bracket 6 can rise and fall with the rotation of support rod 2 4. Bracket 6 is rotatably connected to the inner wall of base 5 on the other side via support rod 3 14 and support rod 4 15.

[0028] Reference Figures 1-4 The limiting component includes a second fixing block 18, a second limiting block 19 fixedly connected to the upper surface of the second fixing block 18, a limiter 20 provided on the upper surface of the second fixing block 18, the limiter 20 is used to limit the cable from falling off, a sliding groove 24 is provided inside the limiter 20, the second limiting block 19 is slidably connected inside the limiter 20, a buckle 21 is fixedly connected to the upper surface of the limiter 20, the buckle 21 is used to prevent the limiter 20 from loosening, a third fixing block 25 is fixedly connected to the upper surface of the bracket 6, and a third limiting block 22 is fixedly connected to the upper surface of the third fixing block 25.

[0029] Specifically, by pushing the second limiting block 19 to slide in the slide groove 24 of the limiter 20, the second limiting block 19 is fixed in the slide groove 24 using the buckle 21 to ensure that the cable will not slip out of the laying frame during the laying process.

[0030] Reference Figures 1-4 One end of the threaded rod 7 is fixedly connected to a handle 10 for driving the threaded rod 7 to rotate. The outer wall of the threaded rod 7 is fixedly connected to a limit block 5 11, which is rotatably connected inside the fixed block 4 9. The outer wall of the threaded rod 7 is fixedly connected to a limit block 4 13, which is rotatably connected inside the fixed block 4 9. A limit rod 12 is provided inside the limit block 5 11 for limiting the limit block 5 11. One end of the threaded rod 7 is fixedly connected to a limit block 13 for limiting the threaded rod 7. A caster 16 is fixedly connected to the lower surface of the base 5. A support block 17 is fixedly connected to the outer wall of the base 5. A threaded rod 26 is threadedly connected inside the support block 17. A roller 23 is fixedly connected inside the bracket 6 to reduce the friction between the cable and the device.

[0031] Specifically, the height of the device is adjusted by rotating the threaded rod 7 by the throttle 10. The limit block 4 13 works in conjunction with the limit rod 12 to ensure the stability of the adjusted height. The limit block 1 3 is used to limit the range of motion of the threaded rod 7. The caster 16 facilitates the movement of the equipment. The threaded rod 26 works in conjunction with the support block 17 to increase the stability of the equipment. The roller 23 reduces the friction between the cable and the device and increases convenience.

[0032] Working principle: When the height of the cable laying frame needs to be adjusted, the throttle handle 10 is turned, which drives the threaded rod 7 to rotate. The threaded rod 7 is internally threaded to the fixed block 8. Therefore, rotating the threaded rod 7 will cause the fixed block 8 to move on the threaded rod. The fixed block 8 is connected to the support rod 1 and support rod 4 through the rotating shaft 2. Therefore, the movement of the fixed block 8 will drive the support rods 1, 4, 14, and 15 to change the angle between each support rod through the rotating shaft 2, thereby adjusting the height. The bracket 6 is connected to the support rod 14 through the rotating shaft 2, and then to the support rod 4 through the rotating shaft 2, which limits the movement. The fitting design of Block 5 11 and Limiting Block 4 13 with Fixed Block 4 9, as well as the setting of Limiting Rod 12, provides additional limiting function to ensure the stability of the bracket 6 after height adjustment. Roller 23 reduces the friction between the device and the cable during laying. When the bracket 6 reaches the required height, it pushes Limiting Block 2 19 to slide in the slide groove 24 of Limiter 20 to the appropriate position. Using buckle 21, Limiting Block 2 19 is fixed in the slide groove 24 to ensure that the cable will not slip outside the laying frame during the laying process. By adjusting the threaded rod 26 to move up and down inside the support block 17, the device can be kept balanced in uneven use scenarios. Casters 16 facilitate movement.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
