Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example: Figure 1-4As shown, the utility model provides a component installation structure of a high-voltage cabinet, including a high-voltage cabinet body 1, a symmetrically distributed installation frame 11 is fixedly installed inside the high-voltage cabinet body 1, a horizontal plate 12 is fixedly installed on one side of the installation frame 11, a fixed plate 13 is fixedly installed on the side of the horizontal plate 12 away from the installation frame 11, a movable plate 14 is arranged inside the installation frame 11, a uniformly distributed fixed rod 15 is fixedly installed on the side of the installation frame 11 away from the horizontal plate 12, a movable rod 16 is movably inserted inside the fixed rod 15, and the movable rod 16 and the movable plate 14 are fixedly installed on the side of the installation frame 11 away from the horizontal plate 12. 14 is fixedly connected, a first spring 17 is fixedly installed on one end of the movable rod 16 away from the movable plate 14, and the other end of the first spring 17 is fixedly connected to the inner wall of the fixed rod 15, and an array of clamping rods 18 are fixedly installed on one side of the movable plate 14 away from the movable rod 16. A plurality of through holes 19 corresponding to the clamping rods 18 are provided on the surface of the fixed plate 13, and two mounting beams 191 are provided inside the high-voltage cabinet body 1, and evenly distributed fixing holes 192 are provided on both sides of the mounting beams 191, and the clamping rods 18 and the fixing holes 192 are used in conjunction with each other.

[0018] A symmetrically distributed pull plate 2 is fixedly installed on one side of the two movable plates 14 away from the clamping rod 18. The pull plate 2 passes through the installation frame 11. A stabilizing plate 21 is fixedly installed on the opposite sides of the two pull plates 2. The stabilizing plate 21 and the installation frame 11 are fixedly connected by two second springs 22.

[0019] A stabilizing rod 3 is fixedly installed at the bottom end of the pull plate 2, and symmetrically distributed stabilizing grooves 31 are provided on the upper surface and the lower surface of the inner wall of the high-voltage cabinet body 1. Multiple stabilizing rods 3 are movably mounted in the corresponding stabilizing grooves 31. By setting the stabilizing rod 3 and the stabilizing grooves 31, the pull plate 2 can be limited to avoid displacement of the pull plate 2 during movement, while improving its stability.

[0020] A symmetrically distributed fan 4 is fixedly installed on one side of the high-voltage cabinet body 1 away from the mounting frame 11. By setting the fan 4, the components in the high-voltage cabinet body 1 can be cooled and their service life can be extended; there are two fans 4 to increase wind force and improve the heat dissipation effect.

[0021] Evenly distributed heat dissipation holes 5 are provided on both sides of the high-voltage cabinet body 1 close to the mounting frame 11. There are four heat dissipation holes 5. By providing the heat dissipation holes 5, the high temperature in the high-voltage cabinet body 1 can be discharged, further improving the service life of the components.

[0023] Working principle: In actual use, by pulling the movable plate 14 away from the horizontal plate 12, the movable plate 14 drives the movable rod 16 to move in the fixed rod 15. At this time, the movable rod 16 squeezes the first spring 17, and then places the two sides of the mounting beam 191 in the movable plate 14 and the fixed plate 13. By stopping the pulling force on the movable plate 14, the compressed first spring 17 releases the elastic force, driving the movable rod 16 and the movable plate 14 to move in the direction of the fixed plate 13. The movable plate 14 drives the clamping rod 18 to move. At this time, the clamping rod 18 enters the fixing hole 192 and the through hole 19 to complete the fixation of the mounting beam 191; by setting the pulling plate 2, it is convenient to pull the movable plate 14 to move, and by setting the second spring 22, the pulling plate 2 can be reset faster, thereby improving the resetting speed of the movable plate 14. At the same time, the stabilizing plate 21 can improve the stability of the pulling plate 2 to prevent the movable plate 14 from deflecting.

[0024] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
