[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0023] Refer to Figures 1-3 , a low-loss indoor distribution cabinet, including a distribution cabinet main body 1. A slide groove 2 is provided at the inner bottom of the distribution cabinet main body 1. The distribution cabinet main body 1 is slidably connected with a mounting rack 3 through the slide groove 2. A fixed seat 4 is fixedly connected to the outer side wall of the mounting rack 3. There are two fixed seats 4. The two fixed seats 4 are respectively located in the direction away from the cabinet door of the distribution cabinet main body 1. Slide rods 5 are fixedly connected to the inner side walls of the two fixed seats 4. Extrusion springs 6 are fixedly connected to the inner side walls of the two fixed seats 4. The two extrusion springs 6 are respectively located outside the two slide rods 5. One ends of the two extrusion springs 6 close to the mounting rack 3 are respectively fixedly connected with slide blocks 7. The inner side walls of the two slide blocks 7 are respectively slidably connected with the outer side walls of the two slide rods 5. Columns 8 are fixedly connected to the tops of the two slide blocks 7. Arc-shaped support plates 9 are fixedly connected to one sides of the two columns 8 close to the mounting rack 3. The two arc-shaped support plates 9 are semi-circular, and the openings of the two arc-shaped support plates 9 both face the mounting rack 3;
[0024] During use, the staff uses the mounting rack 3 to install electrical components. After installation and wiring are completed, the wires are aligned with one side of the arc-shaped support plate 9 at the terminal block. Under the action of the self-elastic force of the two extrusion springs 6, the two slide blocks 7 will move towards the mounting rack 3, thereby pushing the two columns 8 to drive the two arc-shaped support plates 9 to move towards different wire directions respectively, and then the two arc-shaped support plates 9 will squeeze and contact the wires and the terminal block, avoiding the wires from falling off from the terminal block during use, thereby avoiding poor contact between the wires and the terminal block, resulting in power loss, and reducing the temperature of the equipment to avoid safety accidents.
[0025] Refer to Figure 4, a groove 18 is formed at the bottom of the main body 1 of the distribution cabinet. There are two grooves 18, and the two grooves 18 are respectively located on both sides of the inner bottom of the main body 1 of the distribution cabinet. Two arc-shaped blocks 10 are fixedly connected to the bottom of the main body 1 of the distribution cabinet. The two arc-shaped blocks 10 are respectively located inside the two grooves 18. An elastic pin 11 is arranged at the bottom of the mounting rack 3. There are two elastic pins 11, and the two elastic pins 11 are respectively located above the two arc-shaped blocks 10, and the bottoms of the two elastic pins 11 are respectively in contact with the tops of the two arc-shaped blocks 10. During use, the staff can adjust the position of the mounting rack 3. As the two elastic pins 11 move with the mounting rack 3, they will gradually contract into the interior of the mounting rack 3, thereby releasing the blockage of the two grooves 18 on the mounting rack 3, and then facilitating the staff to pull the mounting rack 3 out of the interior of the main body 1 of the distribution cabinet for maintenance and repair.
[0026] Refer to Figure 4 , two fixing frames 12 are fixedly connected to the inner top of the main body 1 of the distribution cabinet. There are two fixing frames 12, and the two fixing frames 12 are symmetrically distributed with respect to the central axis plane of the main body 1 of the distribution cabinet. A set of moving columns 13 are slidably connected to the inner side walls of the two fixing frames 12. Two clamping blocks 14 are respectively fixedly connected to the bottoms of the two sets of moving columns 13, that is, a whole is composed of two moving columns 13 and one clamping block 14. Springs 15 are wound around the outer side walls of the four moving columns 13. After the staff docks the lines, the two clamping blocks 14 are used to clamp and fix the lines, avoiding the long-term downward drop of the lines, and thus avoiding excessive stress on the connection between the lines and the terminal blocks.
[0027] Refer to Figure 4 , four moving wheels 16 are fixedly connected to the bottom of the main body 1 of the distribution cabinet. The four moving wheels 16 are respectively located at the four corners of the bottom of the main body 1 of the distribution cabinet, and the four moving wheels 16 are all universal wheels, which is convenient for the staff to adjust the position of the main body 1 of the distribution cabinet according to the indoor situation.
[0028] Refer to Figure 4 , a handle 17 is fixedly connected to the outer side wall of the mounting rack 3. The handle 17 is located above the bottom of the mounting rack 3, and the top of the handle 17 is arc-shaped, which is convenient for the staff to grasp with their hands. And an insulating material is arranged outside the handle 17 to prevent the staff from getting an electric shock when adjusting the position of the mounting rack 3.
[0029] Refer to Figure 1 , ventilation holes 19 are formed through the outer side wall of the main body 1 of the distribution cabinet. There are two groups of ventilation holes 19, and each group contains multiple ventilation holes 19. The two groups of ventilation holes 19 are respectively located on both sides of the main body 1 of the distribution cabinet. The two groups of ventilation holes 19 improve the air circulation inside the main body 1 of the distribution cabinet, avoiding excessive temperature or humidity inside the main body 1 of the distribution cabinet and improving the service life of electrical components.
[0030] Working principle: When in use, the staff uses the mounting frame 3 to install the electrical components. After the installation and wiring are completed, the wires and the terminal are aligned with one side of the arc-shaped support plate 9. Under the action of the elastic force of the two extrusion springs 6, the two sliders 7 will move toward the mounting frame 3, thereby pushing the two columns 8 to drive the two arc-shaped support plates 9 to move in different line directions respectively, and then the two arc-shaped support plates 9 squeeze and contact the wires and the terminal to avoid the wires and the terminal from falling off during use, thereby avoiding poor contact between the wires and the terminal, resulting in power loss, and reducing the temperature of the equipment to avoid safety accidents.
[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
