Detailed implementation manners

[0027] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments. Embodiment 1

[0028] A high-voltage power cabinet for easy installation and inspection, as Figures 1 - 9 shown, includes a cabinet body 1, a mounting rack 2 and a terminal block 3; three mounting racks 2 are welded inside the cabinet body 1; the terminal block 3 is detachably connected to the mounting rack 2, and a plurality of mounting holes 4 are provided on the terminal block 3;

[0029] It also includes a first mounting plate 5, a push plate 6 and a grip rod 7; two symmetrically arranged first mounting plates 5 are provided on the mounting rack 2 connected to the terminal block 3; a push plate 6 is damping slidably connected in each of the two first mounting plates 5; two grip rods 7 are respectively welded on the two push plates 6.

[0030] In order to facilitate manual gripping of the grip rod 7, the end of the grip rod 7 is set to be spherical.

[0031] In order to facilitate inserting the wire into the mounting hole 4 of the terminal block 3, the front side of the push plate 6 is aligned with the rear side wall of the mounting hole 4 of the terminal block 3.

[0032] In order to avoid scratching the wire, a rubber sleeve is provided on the push plate 6.

[0033] It also includes a limiting plate 8; a number of limiting plates 8 are respectively equidistantly connected to each push plate 6, and each mounting hole 4 on the terminal block 3 is located between two adjacent limiting plates 8.

[0034] In order to isolate two adjacent wires from each other, a rubber sleeve is provided on the limiting plate 8.

[0035] It also includes a U-shaped plate 21, a push block 22, a connecting rod 23, a limiting plate 24 and a connecting plate 25; two U-shaped plates 21 are damping slidably connected to each push plate 6; a number of push blocks 22 are respectively equidistantly welded on each U-shaped plate 21; the push blocks 22 connected to the upper U-shaped plate 21 and the lower U-shaped plate 21 on the same push plate 6 are arranged in a staggered manner; all the limiting plates 8 are connected to the push plate 6 through a torsion spring rotating shaft; each push block 22 is located between two adjacent limiting plates 8, and each push block 22 is in contact with two adjacent limiting plates 8, and the contact surface between the limiting plate 8 and the push block 22 is set to be an inclined surface; a connecting rod 23 is rotatably connected to both ends of each U-shaped plate 21; a limiting plate 24 is fixedly connected to each connecting rod 23; a connecting plate 25 is welded to both ends of each push plate 6.

[0036] In order to facilitate manual pulling of the connecting rod 23, a convex ring is provided at the end of each connecting rod 23.

[0037] In order to facilitate forcing the limiting plate 8 to rotate, the contact part between the push block 22 and the limiting plate 8 is set to be arc-shaped.

[0038] Taking Figure 2 the perspective as a reference, the side where the cabinet body 1 is labeled is the right side, and the side where the mounting rack 2 is labeled is the left side.

[0039] In use, various electrical devices are installed on the mounting bracket 2. Among them, the terminal block 3 is installed on the mounting bracket 2 between two first mounting plates 5. When it is necessary to check the tightness of the wires on the terminal block 3, first, the power is cut off manually. Subsequently, the wires above and below the terminal block 3 are inspected. Taking the inspection of the wires below the terminal block 3 as an example: Manually pull and push the push plate 6 below the terminal block 3 back and forth through the grip rod 7. The push plate 6 moves back and forth in the first mounting plate 5 in a damping manner. Whenever the push plate 6 moves forward, the push plate 6 pushes the wire connected to the lower part of the terminal block 3 outwards, making the wire tend to break away from the terminal block 3. After multiple pushes, the connection state between the wire and the terminal block 3 is observed manually. If the connection is not firm, the wire will break away from the terminal block 3 or become loose from the terminal block 3. In this way, the tightness of the wires can be inspected in batches without manually pulling and detecting each one, greatly improving the inspection efficiency.

[0040] When manually installing the wire into the mounting hole 4 of the terminal block 3, since the size of the mounting hole 4 is small, it is difficult for manual operation to accurately insert the end of the wire. To solve this problem, the front side of the push plate 6 is set to align with the rear side wall of the mounting hole 4 of the terminal block 3, as Figure 3 and Figure 4 shown. At this time, the wire can first lean against the front side of the push plate 6 to make it in the same vertical plane as the mounting hole 4. The operator only needs to make left and right fine adjustments to align with the mounting hole 4 and smoothly insert the wire, improving the installation efficiency.

[0041] To further simplify the wire installation process, several limiting plates 8 are provided on the push plate 6. When installing the terminal block 3, its position is finely adjusted so that the mounting hole 4 of the terminal block 3 is located between two adjacent limiting plates 8. In this way, when the wire leans against the front side of the push plate 6, the wire is located between two adjacent limiting plates 8. Without additional adjustment of the left and right positions, the wire can be accurately aligned with the mounting hole 4, greatly improving the convenience of wire installation. In addition, rubber sleeves are provided on all the limiting plates 8. During use, the limiting plates 8 can also play an insulating role. The adjacent wires are insulated from each other through the limiting plates 8 to prevent accidental contact between adjacent wires due to vibration, external force, or insulation layer damage, resulting in problems such as short circuits.

[0042] Taking the inspection of the wires below the terminal block 3 as an example: Before manually pulling the push plate 6 horizontally through the grip rod 7 to check the tightness of the wires, manually pull the connecting rod 23 located below the push plate 6 forward. The connecting rod 23 pulls the corresponding U-shaped plate 21 to move synchronously, so that the push block 22 on the U-shaped plate 21 forces two adjacent limiting plates 8 to rotate, as Figure 8As shown in the figure, the front parts of two adjacent limit plates 8 are made to approach each other, the torsion spring rotating shaft at the connection between the limit plate 8 and the push plate 6 is stressed, and the electric wire between the two is surrounded. Taking the count from right to left as a reference, the electric wires at odd positions are surrounded, while the electric wires at even positions are not surrounded. Then, manually rotate the pulled link 23 so that the link 23 drives the limiting plate 24 to rotate to the exact front of the connecting plate 25. In this way, the connecting plate 25 restricts the limiting plate 24, preventing the U-shaped plate 21, the push block 22, the link 23, and the limiting plate 24 from moving backward, thereby preventing the limit plate 8 from rotating back to its original position, and ensuring that the electric wires at odd positions are always surrounded. Then, manually push and pull the push plate 6 below the terminal block 3 back and forth through the grip rod 7, so that the push plate 6 drives the limit plate 8 to move back and forth. The limit plate 8 drives the surrounded electric wires at odd positions to move back and forth, causing the electric wires at odd positions to shake. Relatively, the electric wires connected to the terminal block 3 are pushed outwards through the push plate 6, making the electric wires shake relative to the terminal block 3, which is more in line with the force application during manual inspection and ensures the accuracy of the inspection. After inspecting the electric wires at odd positions, first let the U-shaped plate 21 and the push block 22 below move backward to reset. The limit plate 8 is no longer restricted by the push block 22 and is reset under the action of the torsion spring rotating shaft at the connection with the push plate 6. Then, manually control the actions of the U-shaped plate 21 and the push plate 6 located above the push plate 6. The principle is the same as that for inspecting the electric wires at odd positions. Since the push blocks 22 connected to the U-shaped plate 21 above the push plate 6 and the push blocks 22 connected to the U-shaped plate 21 below the push plate 6 are staggeredly distributed, when manually controlling the actions of the U-shaped plate 21 and the push plate 6 located above the push plate 6, as Figure 9 shown in the figure, the limit plate 8 will cause the electric wires at even positions to shake. Embodiment 2

[0043] On the basis of Embodiment 1, as Figure 5 shown in the figure, it further includes a second mounting plate 9 and a third mounting plate 10; two second mounting plates 9 are welded on the cabinet body 1; a third mounting plate 10 is respectively connected in a damping sliding manner in the two second mounting plates 9; the opposite parts of the two first mounting plates 5 are respectively fixed to a third mounting plate 10.

[0044] The front side of the push plate 6 is set to be aligned with the rear side wall of the mounting hole 4 of the terminal block 3, so that when installing the wire, the push plate 6 contacts the part of the wire close to the terminal block 3. When the wire is pushed outwards by the push plate 6, or the odd-numbered wires surrounded are reciprocated back and forth by the limiting plate 8, causing the odd-numbered wires to shake, in order to batch-check the tightness of the wires, the positions where the push plate 6 and the limiting plate 8 push the wires are too close to the connection between the wire and the terminal block 3, resulting in a small degree of shaking of the wire. In this case, not only can't it effectively check whether the wire is loose relative to the terminal block 3, but also the connection between the wire and the terminal block 3 is prone to be damaged due to stress concentration, increasing the risk of electrical connection failure; therefore, before the inspection, the operator manually pulls down the push plate 6 through the holding rod 7, and the push plate 6 drives the third mounting plate 10 to slide dampingly in the second mounting plate 9, so that the push plate 6 and the limiting plate 8 move to a lower position, that is, the push plate 6 and the limiting plate 8 are moved away from the connection between the wire and the terminal block 3, ensuring the stable progress of the inspection, further ensuring the accuracy of the inspection, and avoiding damage to the connection between the wire and the terminal block 3 when the push plate 6 and the limiting plate 8 push the wire.

[0045] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
