[0008] Furthermore, it also includes a limit plate; each push plate is equidistantly connected to a plurality of limit plates, and each mounting hole on the terminal block is located between two adjacent limit plates.

[0009] Furthermore, a rubber sleeve is provided on the limiting plate.

[0010] Furthermore, it also includes a U-shaped plate, a push block, a connecting rod, a limiting plate and a connecting plate; each push plate is respectively connected to two U-shaped plates in a damping sliding manner; each U-shaped plate is respectively fixedly connected with a number of push blocks at equal distances; the push block connected to the upper U-shaped plate of the same push plate and the push block connected to the lower U-shaped plate are staggered; all the limiting plates are connected to the push plate through a torsion spring shaft; each push block is located between two adjacent limiting plates, and each push block is in contact with two adjacent limiting plates, and the contact surface between the limiting plate and the push block is set as an inclined plane; each U-shaped plate is rotatably connected to a connecting rod at both ends; each connecting rod is respectively fixedly connected to a limiting plate; each push plate is respectively fixedly connected to both ends.

DETAILED DESCRIPTION

[0019] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. Example 1

[0020] A high voltage power cabinet that is easy to install and inspect, such as Figure 1-Figure 9 As shown, it includes a cabinet 1, a mounting frame 2 and a terminal block 3; three mounting frames 2 are welded in the cabinet 1; the terminal block 3 is detachably connected to the mounting frame 2, and a plurality of mounting holes 4 are provided on the terminal block 3; It also includes a mounting plate 5, a push plate 6 and a gripping rod 7; two mounting plates 5 symmetrically arranged on the mounting frame 2 connected to the terminal block 3; a push plate 6 is respectively connected to the two mounting plates 5 in a damping sliding manner; and two gripping rods 7 are respectively welded to the two push plates 6.

[0021] In order to facilitate manual gripping of the gripping rod 7 , the end of the gripping rod 7 is configured to be spherical.

[0022] In order to facilitate the insertion of 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 .

[0023] In order to avoid scratching the electric wires, a rubber sleeve is provided on the push plate 6 .

[0024] It also includes a limiting plate 8 ; a plurality of limiting plates 8 are 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 .

[0025] In order to isolate two adjacent electric wires, a rubber sleeve is provided on the limiting plate 8 .

[0026] 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; each push plate 6 is respectively connected to two U-shaped plates 21 in a damping sliding manner; each U-shaped plate 21 is respectively welded with a number of push blocks 22 at equal distances; the push block 22 connected to the upper U-shaped plate 21 of the same push plate 6 is staggered with the push block 22 connected to the lower U-shaped plate 21; all the limiting plates 8 are connected to the push plate 6 through the torsion spring 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 as an inclined surface; each U-shaped plate 21 is rotatably connected to a connecting rod 23 at both ends; each connecting rod 23 is respectively fixed with a limiting plate 24; each push plate 6 is respectively welded with a connecting plate 25 at both ends.

[0027] In order to facilitate manual pulling of the connecting rod 23 , a convex ring is provided at the end of each connecting rod 23 .

[0028] In order to facilitate forcing the limiting plate 8 to rotate, the contact point between the push block 22 and the limiting plate 8 is configured to be arc-shaped.

[0029] by Figure 2 The viewing angle is used as a reference, wherein the side where the cabinet 1 is located is the right side, and the side where the mounting frame 2 is located is the left side.

[0030] When in use, various electrical equipment are installed on the mounting frame 2, wherein the terminal block 3 is installed on the mounting frame 2 between two mounting plates 5; when it is necessary to check the tightness of the wires on the terminal block 3, firstly, the power-off operation is manually performed, and then the wires at the upper and lower parts of the terminal block 3 are checked; taking the inspection of the wires at the lower part of the terminal block 3 as an example: manually pull and push the push plate 6 under the terminal block 3 back and forth through the grip 7, and the push plate 6 moves back and forth in a damping manner in the mounting plate 5. Whenever the push plate 6 moves forward, the push plate 6 pushes the wires connected to the lower part of the terminal block 3 outward, so that the wires tend to be detached from the terminal block 3. After multiple pushes, the connection status of the wires and the terminal block 3 is manually observed. If the connection between the two is not firm, the wires are detached from the terminal block 3, or the wires are loosened from the terminal block 3, so that the tightness of the wires can be batch checked without manual pulling and testing one by one, thereby greatly improving the inspection efficiency.

[0031] When manually installing the wire into the mounting hole 4 of the terminal block 3, it is difficult to insert the wire end accurately due to the small size of the mounting hole 4. To solve this problem, the front side of the push plate 6 is arranged to be aligned with the rear side wall of the mounting hole 4 of the terminal block 3, such as Figure 3 and Figure 4 As shown; at this time, the wire can be first placed against the front side of the push plate 6 so that it is in the same vertical plane as the mounting hole 4. The operator only needs to make fine adjustments left and right to align the mounting hole 4 to smoothly insert the wire and improve installation efficiency.

[0032] To further simplify the installation process of the wires, a number of limit plates 8 are provided on the push plate 6. When installing the terminal block 3, its position is fine-tuned so that the mounting hole 4 of the terminal block 3 is located between two adjacent limit plates 8; in this way, when the wire is against the front side of the push plate 6, the wire is located between two adjacent limit plates 8. There is no need to adjust the left and right positions additionally, so that the wire can be accurately aligned with the mounting hole 4, which greatly improves the convenience of wire installation; in addition, all the limit plates 8 are provided with rubber sleeves. When in use, the limit plates 8 can also play an isolating role. The limit plates 8 can isolate two adjacent wires to avoid accidental contact between adjacent wires due to vibration, external force or damage to the insulation layer, resulting in short circuits and other problems.

[0033] Take checking the wires at the bottom of the terminal block 3 as an example: before manually pulling the push plate 6 horizontally through the grip 7 to check the tightness of the wires, manually pull the connecting rod 23 located at the bottom of the push plate 6 to move forward, and 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 the two adjacent limit plates 8 to rotate, such as Figure 8As shown, the front parts of the two adjacent limit plates 8 are brought together, the torsion spring shaft at the connection between the limit plate 8 and the push plate 6 is stressed, and the wires between the two are enclosed. Based on the numbering from right to left, the odd-numbered wires are enclosed, and the even-numbered wires are not enclosed. Then the pulled-out connecting rod 23 is manually rotated so that the connecting rod 23 drives the limit plate 24 to rotate to the front of the connecting plate 25, so that the limit plate 24 is restricted by the connecting plate 25 to prevent the U-shaped plate 21, the push block 22, the connecting rod 23 and the limit plate 24 from moving backward, thereby preventing the limit plate 8 from rotating and resetting, so that the odd-numbered wires are always enclosed; then the push plate 6 under the terminal row 3 is manually pushed and pulled back and forth through the grip 7, so that the push plate 6 drives the limit plate 8 to move back and forth, and the limit plate 8 moves back and forth with the enclosed odd-numbered wires, so that the odd-numbered wires are always enclosed. When the odd-numbered wires shake, the wires connected to the terminal block 3 are pushed outward by the push plate 6, so that the wires shake relative to the terminal block 3, which is more in line with the manual inspection force and ensures the accuracy of the inspection. After checking the odd-numbered wires, first let the lower U-shaped plate 21 and the push block 22 move backward and reset, and the limit plate 8 is no longer restricted by the push block 22. The limit plate 8 is reset by the torsion spring shaft at the connection with the push plate 6, and then the U-shaped plate 21 and the push plate 6 located on the upper part of the push plate 6 are manually controlled to move. The principle is the same as that of checking the odd-numbered wires. Since the push block 22 connected to the U-shaped plate 21 located on the upper part of the push plate 6 and the push block 22 connected to the U-shaped plate 21 located on the lower part of the push plate 6 are staggered, therefore, when the U-shaped plate 21 and the push plate 6 located on the upper part of the push plate 6 are manually controlled to move, such as Fig. 9 As shown, the limiting plate 8 will cause the even-numbered wires to shake. Example 2

[0034] On the basis of Example 1, Figure 5 As shown, it also includes a mounting plate 2 9 and a mounting plate 3 10; two mounting plates 2 9 are welded on the cabinet 1; a mounting plate 3 10 is respectively connected in a damping sliding manner in the two mounting plates 2 9; and the backs of the two mounting plates 1 5 are respectively fixedly connected to a mounting plate 3 10.

[0035] The front side of the push plate 6 is arranged 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 is in contact with the part of the wire close to the terminal block 3, and when the wire is pushed outward by the push plate 6, or the odd-numbered wires surrounded by the limit plate 8 are moved back and forth, so that the odd-numbered wires shake, when checking the tightness of the wires in batches, the position where the push plate 6 and the limit plate 8 push the wire is 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 it be effectively checked whether the wire is relative to the terminal block 3 If the wires are loose, the connection between the wires and the terminal block 3 is easily damaged due to stress concentration, increasing the risk of electrical connection failure. Therefore, before inspection, the push plate 6 is manually pulled downward by the grip 7, and the push plate 6 drives the mounting plate three 10 to slide in a damping manner within the mounting plate two 9, so that the push plate 6 and the limit plate 8 are moved to a lower position, that is, the push plate 6 and the limit plate 8 are moved away from the connection between the wires and the terminal block 3, ensuring that the inspection is carried out stably, further ensuring the accuracy of the inspection, and avoiding damage to the connection between the wires and the terminal block 3 when the push plate 6 and the limit plate 8 push the wires.

[0036] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
