[0031] Example 4: Please refer to Figure 6 , Figure 7 , this embodiment further explains the first embodiment, an adjustment component is installed on the outer side of the second socket 27, and the adjustment component includes a connecting plate 35 fixedly installed on the end of the rectangular rod 31 away from the support rod 26, and two symmetrically distributed hemispherical bodies 36 are fixedly installed on the side of the connecting plate 35 close to the second socket 27, and a U-shaped sleeve 37 is movably sleeved on the outer side of the second socket 27, and four limit sliders 38 symmetrically distributed in pairs are fixedly installed on the side of the U-shaped sleeve 37 close to the second socket 27, and the limit slider 38 is close to the end of the U-shaped sleeve 37, and the limit slider 38 moves in the movable groove, which can prevent the U-shaped sleeve 37 from detaching from the second socket 27.

[0032] The limiting slider 38 is slidably connected to the second socket seat 27 through a movable groove, and a fourth spring 39 is fixedly installed at the center of one side of the U-shaped sleeve 37 close to the second socket seat 27, and the end of the fourth spring 39 away from the U-shaped sleeve 37 is fixedly connected to the second socket seat 27, and the fourth spring 39 can drive the U-shaped sleeve 37 to move. Four second driving blocks 40 symmetrically distributed in pairs are fixedly installed on the outer side of the U-shaped sleeve 37, and a slope 2 is provided at one end of the second driving block 40 close to the hemisphere 36. The hemisphere 36 is in sliding contact with the second driving block 40 through the slope 2. The hemisphere 36 is used to reduce the friction resistance between the connecting plate 35 and the second driving block 40. The U-shaped sleeve 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.

[0033] Working principle: When it is necessary to inspect and repair the electronic components in the switch cabinet body 1, the personnel opens the cabinet door 2, rotates the cabinet door 2 to a suitable angle, holds the cabinet door 2 with one hand, and rotates the carrier 6 with the other hand to rotate the carrier 6 to a horizontal state. During this process, the connecting rod 10 slides on the first slot rod 7 through the limiting straight groove 11, and when it moves to the inclined baffle 12, it presses 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 slot rod 8, the upper end of the inclined baffle 12 presses against the first slot rod 8 under the drive of the compression elastic force of the arc spring 13. Rod 7, so the inclined baffle 12 cannot rotate to the left, so that the connecting rod 10 can be locked by the inclined baffle 12, and then the personnel can place the electronic components and other parts removed from the switch cabinet body 1 on the carrier 6. After the inspection is completed, the personnel will rotate the carrier upward for a distance, and then press the inclined baffle 12 to make the inclined baffle 12 horizontal. At this time, the connecting rod 10 can move freely in the limiting straight groove 11, and can make the carrier 6 fold and fit the cabinet door 2, which can effectively prevent the carrier 6 from being installed on the outside of the switch cabinet body 1 to hinder personnel, and can also prevent the carrier 6 from being hit.

[0034] During the process of the carrier 6 rotating to the horizontal state, the first driving block 24 rotates therewith. During the rotation of the first driving block 24, the curved edge portion 25 and the ball 23 drive the bent top rod 22, the bent connecting rod 18 and the curved rubber pad 16 to move, so that the curved rubber pad 16 is against the multiple convex teeth 17 on the outside of the first connecting seat 3, so as to lock the position of the cabinet door 2, which can prevent the cabinet door 2 from rotating and colliding with personnel under the action of gravity after the personnel place the electronic components to be repaired on the carrier 6; after the carrier 6 rotates to the vertical state, the ball 23 disengages from the first driving block 24. During this process, the curved rubber pad 16 will move back and reset under the drive of the compression elastic force of the first spring 21, and the cabinet door 2 can rotate normally at this time.

[0035] After the carrier plate 6 is rotated to a horizontal state and the locking assembly locks the position of the cabinet door 2, the person moves the support rod 26 downward through the pressure plate 28. After the support rod 26 touches the ground, the rectangular rod 31 is inserted into the pin hole 34 driven by the compression force of the third spring 33 to position the support rod 26. At this time, when placing objects on the carrier plate 6, the support rod 26 can support the lower left corner of the cabinet door 2, which can effectively reduce the burden of the connecting assembly and extend the service life of the connecting assembly.

[0036] After the carrier plate 6 is rotated to a vertical state and the locking assembly releases the lock on the cabinet door 2, the person pushes the U-shaped sleeve 37 with his feet. During the movement of the second drive block 40 along with the U-shaped sleeve 37, the second drive 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, releasing the positioning of the support rod 26. At this time, the support rod 26 will move up and reset under the drive of the compression force of the second spring 29, and will not hinder the closing of the cabinet door 2.
