[0028] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figures 1 to 9 This embodiment provides a safety protection structure for a high-voltage switchgear, including a high-voltage switchgear 400. Several control buttons 401 are provided on the outer wall of the high-voltage switchgear 400. A hanging baffle 402 is fixedly installed at one end of the outer wall of the high-voltage switchgear 400. A control partition 100 is fixed to the outer wall of the high-voltage switchgear 400. The control partition 100 is a cuboid with one open end and a wavy shape at the other end. Several through holes 101a are provided on the outer wall of the control partition 100, with positions corresponding to the pivot pins 301. A spring element 200 and an adjusting element 300 are provided at each through hole 101a. The adjusting element 300 cooperates with the spring element 200 and with the control buttons 401. The control partition 100 is fixed to the outer wall of the high-voltage switchgear 400 by the hanging baffle 402 and fixing bolts. The entire control partition 100 is made of transparent insulating material.

[0031] A first connecting cylinder 102a is provided on the inner wall of the control partition 100 at the through hole 101a. A rotating groove 101a-1 is opened on the inner wall of the through hole 101a. The through hole 101a, the rotating groove 101a-1 and the first connecting cylinder 102a are all coaxially arranged. The elastic element 200 includes a toggle rod 201. A square groove 201a is opened through the outer wall of the toggle rod 201. A second connecting cylinder 201b with a size adapted to the first connecting cylinder 102a is provided at one end of the outer wall of the toggle rod 201. A rotating edge 201c is provided at the end of the second connecting cylinder 201b. The rotating edge 201c is rotatably connected inside the rotating groove 101a-1. Since the rotating edge 201c is rotatably connected inside the rotating groove 101a-1, the toggle rod 201 as a whole can rotate about the axis of the first connecting cylinder 102a with the height limited. The control button 401 is turned by rotating the toggle rod 201.

[0032] The adjusting component 300 includes a pivot pin 301, with a round rod 301a at its top and a square rod 301b at its top. The pivot pin 301, round rod 301a, square rod 301b, square groove 201a, and second connecting cylinder 201b are all coaxially arranged. The opening shape of the square groove 201a and the cross-sectional shape of the square rod 301b are both rectangular. The cross-sectional shape of the round rod 301a is a circle inscribed within the aforementioned rectangle. Both the round rod 301a and the square rod 301b are slidably connected within the square groove 201a. Lifting the pivot pin 301 causes the round rod 301a and the square rod 301b to slide within the square groove 201a. The square rod 301b slides up and down inside the square groove 201a. As the pivot pin 301 slides up and down, when the square rod 301b is completely disengaged from the square groove 201a, the outer wall of the round rod 301a is tangent to the inner wall of the square groove 201a. The actuating rod 201 is in a non-fixed state at 202. In this state, both the actuating rod 201 and the pivot pin 301 can rotate independently. When the square rod 301b is inside the square groove 201a, the outer wall of the square rod 301b is in contact with the inner wall of the square groove 201a. At this time, it is in a fixed state. In this state, if either the actuating rod 201 or the pivot pin 301 is rotated, the other will be driven to rotate in the same direction.

[0033] The pivot pin 301 is rotatably connected inside the first connecting cylinder 102a of the control partition 100. An energy storage spring 102b is fixedly connected inside the first connecting cylinder 102a, and the other end of the energy storage spring 102b is fixedly connected to the outer wall of the pivot pin 301. Under normal use, the lever 201 does not contact the control button 401. When the control button 401 needs to be pressed, the pivot pin 301 is slid upwards, causing the pivot pin 301 to be in a loose state relative to the lever 201. At this time, the pivot pin 301 is rotated, and because the energy storage spring 102b is connected to the outer wall of the pivot pin 301, energy is stored in the rotation. After energy storage is complete, the pivot pin 301 is slid downwards, and the pivot pin 301 is fixed to the lever 201. Throughout the above process, the end of the lever 201 is kept from contacting the control button 401. When the control button 401 is in contact, and the pivot pin 301 and the lever 201 are in a fixed state, the user releases the pivot pin 301. At this time, the energy storage spring 102b drives the pivot pin 301 to rotate, which in turn drives the lever 201 to rotate. The rotation of the lever 201 causes its end to contact the control button 401, thereby controlling the control button 401. After the lever 201 contacts the control button 401, it will continue to rotate due to the remaining potential energy, causing it to disconnect from the control button 401 and move to the other end. When the adjustment component 300 needs to be used again, the operation process is similar to the above process, but the pivot pin 301 needs to be rotated in the opposite direction to the previous rotation.

[0034] The square rod 301b is provided with a circular top cover 301c. The cross-sectional area of ​​the top cover 301c is larger than that of the square rod 301b. The function of the top cover 301c is to limit the feed degree of the square rod 301b at the square groove 201a, so as to facilitate the determination of the state of the actuating rod 201 and the pivot pin 301.
