The rectangular rod 31 is clamped into the pin holes 34 under the driving of the compression elastic force of the third spring 33, and can position the support rod 26.

[0040] Embodiment 4: Please refer to Figure 6 , Figure 7, This embodiment further elaborates on the first embodiment. An adjustment component is installed on the outer side of the second socket 27. The adjustment component includes a connecting plate 35 fixedly installed at the end of the rectangular rod 31 away from the support rod 26. On the side of the connecting plate 35 close to the second socket 27, two symmetrically distributed hemispheres 36 are fixedly installed. A U-shaped sleeve plate 37 is movably sleeved on the outer side of the second socket 27. On the side of the U-shaped sleeve plate 37 close to the second socket 27, four symmetrically distributed limit sliders 38 are fixedly installed, and the limit sliders 38 are close to the end of the U-shaped sleeve plate 37. The limit sliders 38 move in the moving groove, which can prevent the U-shaped sleeve plate 37 from detaching from the second socket 27.

[0041] The limit slider 38 is slidably connected to the second socket 27 through the moving groove. At the center of the side of the U-shaped sleeve plate 37 close to the second socket 27, a fourth spring 39 is fixedly installed, and the end of the fourth spring 39 away from the U-shaped sleeve plate 37 is fixedly connected to the second socket 27. The fourth spring 39 can drive the U-shaped sleeve plate 37 to move. On the outer side of the U-shaped sleeve plate 37, four symmetrically distributed second driving blocks 40 are fixedly installed. At one end of the second driving block 40 close to the hemisphere 36, a second slope is provided. The hemisphere 36 is in sliding contact with the second driving block 40 through the second slope. The hemisphere 36 is used to reduce the frictional resistance between the connecting plate 35 and the second driving block 40. The U-shaped sleeve plate 37 can drive the connecting plate 35 and the rectangular rod 31 to disengage from the pin hole 34 through the second driving block 40 and the hemisphere 36.

[0042] Working principle: When it is necessary to repair the electronic components in the switch cabinet body 1, the personnel open the cabinet door 2. After rotating the cabinet door 2 to an appropriate angle, the personnel hold the cabinet door 2 with one hand and rotate the carrier plate 6 with the other hand to make the carrier plate 6 rotate to a horizontal state. During this process, the connecting rod 10 slides on the first groove rod 7 through the limit straight groove 11, and when moving to the inclined baffle 12, it abuts against the inclined baffle 12 and drives it to rotate to the right. When the connecting rod 10 moves to the side of the inclined baffle 12 close to the second groove rod 8, since the upper end of the inclined baffle 12 abuts against the first groove rod 7 under the driving force of the compressed elastic force of the arc spring 13, the inclined baffle 12 cannot rotate to the left, so the connecting rod 10 can be locked by the inclined baffle 12. Then, the personnel can place the disassembled electronic components and other parts in the switch cabinet body 1 into the carrier plate 6. After the repair is completed, the personnel rotate the carrier plate up a certain distance, and then press the inclined baffle 12 to make the inclined baffle 12 in a horizontal state. At this time, the connecting rod 10 can move freely in the limit straight groove 11, and the carrier plate 6 can be folded and attached to the cabinet door 2, which can effectively prevent the carrier plate 6 installed on the outer side of the switch cabinet body 1 from hindering the personnel, and can also prevent the carrier plate 6 from being collided.

[0043] During the process of the carrier tray 6 rotating to the horizontal state, the first driving block 24 rotates together with it. During the rotation of the first driving block 24, the bending ejector rod 22, the bending connecting rod 18 and the arc-shaped rubber pad 16 are driven to move through the arc edge part 25 and the ball 23, so that the arc-shaped rubber pad 16 abuts against a plurality of convex teeth 17 on the outside of the first connecting seat 3, thereby locking the position of the cabinet door 2, which can prevent the cabinet door 2 from rotating and colliding with people under the action of the object gravity after the electronic components to be repaired are placed on the carrier tray 6; after the carrier tray 6 rotates back to the vertical state, the ball 23 disengages from the first driving block 24. During this process, the arc-shaped rubber pad 16 will move back and reset under the driving of the compression elastic force of the first spring 21. At this time, the cabinet door 2 can rotate normally.

[0044] After rotating the carrier tray 6 to the horizontal state and the locking assembly locks the position of the cabinet door 2, the operator moves the support rod 26 downward through the pressing plate 28. After the support rod 26 contacts the ground, the rectangular rod 31 will be inserted into the pin hole 34 under the driving of the compression elastic force of the third spring 33 to position the support rod 26. At this time, when placing an object through the carrier tray 6, the lower left corner of the cabinet door 2 can be supported by the support rod 26, which can effectively reduce the burden on the connecting assembly and extend the service life of the connecting assembly.

[0045] After rotating the carrier tray 6 back to the vertical state and the locking assembly releases the lock on the cabinet door 2, the operator pushes the U-shaped sleeve plate 37 with the foot. During the movement of the second driving block 40 along with the U-shaped sleeve plate 37, the second driving block 40 drives the hemisphere 36 and the rectangular rod 31 to move through the second slope. The rectangular rod 31 moves out of the pin hole 34 to release the positioning of the support rod 26. At this time, the support rod 26 will move up and reset under the driving of the compression elastic force of the second spring 29 and will not hinder the closing of the cabinet door 2.
