Description

Technical Field

[0001] This utility model belongs to the technical field of power distribution cabinet structure design, specifically relating to a line fixing device for power distribution cabinets. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] In power distribution cabinets, the layout and securing of wiring are crucial. Traditional wiring securing methods often employ simple cable ties or clips, but these methods have many drawbacks. For example, cable ties may age and break after prolonged use, leading to loose wiring, affecting the normal operation of the distribution cabinet, and potentially causing safety accidents. Clip securing methods, on the other hand, may not effectively secure wiring when the distribution cabinet is subjected to vibration or changes in wiring, causing wire displacement, tangling, short circuits, and other problems. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 4 As shown, this utility model embodiment provides a line fixing device for a power distribution cabinet, specifically including a distribution cabinet body 1, a mounting base 2 installed inside the distribution cabinet body 1, a base 4 provided inside the mounting base 2, a sliding groove 5 opened on the top of the base 4, a lower clamping plate 7 fixedly installed on the top of the base 4, the top of the lower clamping plate 7 having an opening matching the sliding groove 5, a sliding column 6 slidably connected inside the sliding groove 5, the sliding column 6 passing through the opening on the lower clamping plate 7, an upper clamping plate 8 fixedly installed on the top of the sliding column 6, the upper clamping plate 8 matching the lower clamping plate 7. A return spring 18 is provided inside the sliding column 6, one end of the return spring 18 is fixed to the bottom wall of the sliding groove 5, and the other end of the return spring 18 is fixed to the top wall of the sliding column 6.

[0027] In this specific embodiment, the mounting base 2 is fixed to the inner wall of the main body 1 of the distribution cabinet, and the base 4 is movably connected inside the mounting base 2 to provide cushioning, reducing vibration when the parts on the base 4 are shaken. The lower clamping plate 7 is fixed to the base 4, allowing the power lines to be placed on it and fixed by the clamping force between the upper clamping plate 8 and the lower clamping plate 7. The upper clamping plate 8 can move up and down. When moving upward, the upper clamping plate 8 drives the sliding column 6 to move. The bottom of the sliding column 6 is open and hollow, allowing for the insertion of... The return spring 18 is stretched by the slide column 6, creating a distance between the upper clamping plate 8 and the lower clamping plate 7. The wire is then placed in the space, and the upper clamping plate 8 is released. The elasticity of the return spring 18 causes the upper clamping plate 8 to return to its original position, fixing the wire between the lower clamping plate 7 and the upper clamping plate 8, thus securing the wire. In conjunction with the rubber pad and anti-slip texture, the wire is firmly fixed, preventing damage to the wire. The installation and removal of the wire are convenient and quick, facilitating the maintenance and repair of the wire.

[0028] Please see Figures 1 to 4 As shown, limiting grooves 10 are provided on both sides of the inner circumference of the slide groove 5, and limiting blocks 9 are fixed on both sides of the circumference of the slide column 6. The two limiting blocks 9 are respectively embedded and slidably connected in the two limiting grooves 10. When the slide column 6 slides in the slide groove 5, the limiting blocks 9 and limiting grooves 10 limit the position of the slide column 6 to a linear motion, and prevent the slide column 6 from falling out of the slide groove 5. The top two sides of the lower clamping plate 7 are symmetrically provided with arc-shaped grooves 17. The bottom surface of the upper clamping plate 8 and the two arc-shaped grooves 17 are provided with rubber pads and anti-slip textures. The arc-shaped grooves 17 can make the line better positioned on the lower clamping plate 7, and it is not easy to cause displacement during and after fixing. The rubber pads and anti-slip textures can firmly fix the line when fixing the line on the lower clamping plate 7 and the upper clamping plate 8, while avoiding damage to the line. Moreover, the installation and removal of the line is convenient and quick, which facilitates the maintenance and repair of the line.

[0029] Please see Figures 1 to 4As shown, the top of the base 4 has four sets of sockets 13, and a U-shaped cable tie 14 is movably inserted into each set of sockets 13. Through the provided sockets 13 and the U-shaped cable tie 14, the U-shaped cable tie 14 is interference-fitted into the sockets 13, and the cable passes through the underside of the U-shaped cable tie 14 and is then fixed by the lower clamping plate 7 and the upper clamping plate 8. This can further plan and fix the cable. At the same time, when fixing the cable with the lower clamping plate 7 and the upper clamping plate 8, after the upper clamping plate 8 is pulled up, the U-shaped cable tie 14 can be embedded between the lower clamping plate 7 and the upper clamping plate 8 to block it, making it convenient to place the cable between the lower clamping plate 7 and the upper clamping plate 8. A handle 12 is fixed to the top of the upper clamping plate 8. The top of the upper clamping plate 8 is also provided with multiple evenly distributed heat dissipation holes 11. The handle 12 makes it easy to lift the upper clamping plate 8, and the heat dissipation holes 11 help the circuit dissipate heat during operation, avoiding the impact of heat accumulation on the circuit performance.

[0030] Please see Figures 1 to 4 As shown, the top of the base 4 has multiple cable passage holes 15, all of which pass through the mounting base 2. These holes facilitate downward cable routing without obstruction. Multiple evenly distributed buffer springs 3 are fixed to the bottom wall of the mounting base 2, with their tops fixed to the bottom of the base 4. The mounting base 2 is then bolted and threaded into the fixing block 16 and fixed to the inner wall of the distribution cabinet body 1. This design, using the buffer springs 3 to fix the base 4 within the mounting base 2, allows the base 4 to slide up and down within the mounting base 2. This effectively reduces the impact of distribution cabinet vibration on the cable fixing device, ensuring cable stability and reducing the risk of cable displacement or loosening due to vibration, thereby improving the safety and reliability of the power distribution cabinet.

[0031] The working principle and usage process of this utility model are as follows: When using this device, the upper clamping plate 8 is lifted by the handle 12. The upper clamping plate 8 is stretched by the sliding column 6 driving the return spring 18. At this time, a distance is created between the upper clamping plate 8 and the lower clamping plate 7. Then, the wire is placed in the arc groove 17, the upper clamping plate 8 is released, and the upper clamping plate 8 is reset by the elasticity of the return spring 18, fixing the wire between the lower clamping plate 7 and the upper clamping plate 8, thus completing the fixing of the wire. At the same time, with the rubber pad and anti-slip texture, the wire can be firmly fixed and damage to the wire can be avoided. Moreover, the installation and removal of the wire is convenient and quick, which facilitates the maintenance and repair of the wire.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
