[0061] Please refer to Figure 9 and Figures 15-16 , the second rotating device 94 is similar to the first rotating device 93, and the difference is only that the second rotating device 94 lacks the guide rod 933.

[0062] When the maintenance is completed, the height of the inner box body 12 needs to be lifted, at this time the first rotating device 93 is pulled back, under the guidance of the arc-shaped chute on the top of the arc-shaped plate 10 to the guide rod 933, the rotating sleeve 931 moves to the direction close to the first rotating device 93, at this time the ratchet in the rotating sleeve 931 re-engages with the ratchet wheel 92, the first rotating device 93 is locked after being pulled back with the clamping seat 11 to prevent resetting, avoiding the reverse rotation of the first rotating arm 5 under the influence of the self-weight of the inner box body 12 when the second rotating device 94 rotates back, at this time the second rotating device 94 is installed at the ratchet wheel 92 on the right side, at this time the second rotating device 94 is rotated, the ratchet in the second rotating device 94 engages with the ratchet wheel 92 to drive the adjusting shaft 91 to rotate, and the adjusting gear 96 is synchronously rotated, the bottom of the strip-shaped plate 984 is provided with a rack, the rack is engaged with the adjusting gear 96, so that the adjusting gear 96 drives the rack and the strip-shaped plate 984 to move forward in the process of rotating, at the same time the travel plate 981 and the front sliding rod 982 are pushed to move forward, the front sliding rod 982 pushes the first rotating arm 5 to rotate, thereby driving the first rotating arm 5 to reset, in the process, the height of the bearing table 8 is lifted, and the inner box body 12 is restored to the initial height, thereby completing the resetting of the inner box body 12, the whole operation is more simple and convenient, when the inner box body 12 is restored to the initial height, at this time the connecting rod 18 drives the rotating plate 133 to rotate and restores it to the horizontal state, the travel frame 131 is pushed to move to the direction close to the back of the cabinet 1, so that the bottom of the rotating plate 133 contacts the top surface of the cabinet 1, thereby making the fixing device 13 play a role in suspending and supporting the inner box body 12, so that the inner box body 12 is fixed, and then the locking rod 142 is reset under the elastic force of the spring rod 144, and is re-inserted into the inside of the insertion hole 138 and locked.

[0063] When the fixing device 13 is suspended and fixed to the inner box body 12 through the connection with the connecting rod 18, at this time the first rotating device 93 is repeatedly pushed to move to one side, so that the ratchet in the rotating sleeve 931 is out of contact with the ratchet wheel 92 and is unlocked, and the second rotating device 94 is disassembled, at this time the second rotating arm 6 is manually pulled again to rotate, thereby making the bearing table 8 move downward, so that the top surface of the bearing table 8 is out of contact with the inner box body 12, at this time the sliding plate 4 can be moved left and right, and the position thereof is adjusted, thereby enabling different inner box bodies 12 to be disassembled and installed, and the practicability of the device is improved.

[0067] In the process of lowering the height of the inner box body 12 and moving towards the front of the cabinet body 1 and rotating the first rotating arm 5 and the second rotating arm 6, the rotating plate 133 is rotated at the same time, and in this process, the pneumatic rod 134 is stretched and generates damping effect, at the same time, in the process of rotating the first rotating arm 5 and the second rotating arm 6, the distance between the first rotating arm 5 and the second rotating arm 6 is reduced, so as to drive the rear sliding rod 993 to move towards the front sliding rod 982, at this time, the elastic force of the spring outside the spring limiting rod 983 also generates resistance to the displacement of the inner box body 12, avoiding the speed of the inner box body 12 being too fast to cause harm to the operator, and improving the safety of the device.

[0068] Please refer to Figure 1 and Figures 17-19 The bottom surface of the rotating plate 133 is in contact with the top surface of the cabinet body 1 in the initial state, and the locking rod 142 is inserted into the inside of the insertion hole 138 in the initial state.

[0069] When the inner box 12 needs to be overhauled, at this time, the height of the inner box 12 needs to be lowered, the first rotating device 93 is first pushed upwards, so that the guide rod 933 moves along the arc-shaped sliding groove at the top of the arc-shaped plate 10, and the first rotating device 93 is pushed to move to one side, so that the internal ratchet of the rotating sleeve 931 is out of contact with the ratchet wheel 92 and is unlocked, in the process of being pushed upwards, the handle 932 drives the push rod 17 and the top rod 16 to move towards the locking device 14, the front end of the top rod 16 pushes the inclined groove 143 and drives the locking device 14 to move downwards as a whole, so that the locking rod 142 is out of contact with the insertion hole 138 and the first safety is released, then the handle 132 is pulled and the travel frame 131 is dragged to move, so that the bottom surface of the rotating plate 133 is out of contact with the top surface of the cabinet 1, at this time, the rotating plate 133 is completely located above the installation slot 2 and cannot play a supporting role, at this time, the second safety is released, the operator can pull the inner box 12 outwards at this time, under the action of the gravity of the inner box 12, the second rotating arm 6 and the first rotating arm 5 rotate, and the height of the bearing table 8 is lowered, since the inner box 12 is located at the top of the bearing table 8 at this time, the height is lowered synchronously, and at the same time, the bearing table 8 is lowered, and is also moved towards the front of the cabinet 1 synchronously, so as to facilitate the maintenance and overhaul of the electrical elements and the circuit in the inner box 12 by the maintenance personnel, and the convenience of the device is improved.

[0070] After the locking rod 142 is inserted into the insertion hole 138 at the top to achieve locking, at this time, the travel frame 131 cannot be directly dragged from the outside, avoiding the problem that the fixed device 13 arranged on the outside directly drags the inner box 12 to be released by irrelevant personnel, and at the same time, when the operator disassembles, the problem that the operator pulls the wrong travel frame 131 to cause the inner box 12 not supported by the bearing table 8 to be released by mistake is avoided, in addition, after the lifting of the inner box 12 is completed, if the operator forgets to reset the fixed device 13, when the resetting operation of the first rotating device 93 is performed and the second rotating device 94 is disassembled, the inner box 12 will be inclined forward under the influence of the self-weight, so as to remind the operator of the effect of the locking operation not being completed, avoiding the problem that the weight of the inner box 12 is completely borne by the first rotating arm 5 and the second rotating arm 6 to cause the structure to be damaged, and the reliability of the device is improved.

[0071] The present application adopts two safety measures to ensure correct operation, the first safety measure is that rotating the handle 932 to realize disengagement of the inner ring ratchet of the rotating sleeve 931 and the ratchet wheel 92 to realize unlocking, the second safety measure is that dragging the stroke frame 131 to realize disengagement of the rotating plate 133 and the top surface of the cabinet body 1 to realize unlocking, only when both safety measures are unlocked, the operation of reducing the height of the inner box body 12 can be realized, and the pre-operation of unlocking the second safety measure is that rotating the handle 932 to push the push rod 17, so the operator needs to unlock the first safety measure to unlock the second safety measure, which ensures the correct sequence of operation, and when the inner box body 12 is lifted, the first rotating device 93 needs to be rotated and the handle 932 is locked with the clamping seat 11, at this time, the ratchet of the inner ring of the rotating sleeve 931 can limit the ratchet wheel 92, preventing the adjusting device 9 from rotating during the lifting of the inner box body 12, and after the first rotating device 93 is rotated, the top rod 16 and the push rod 17 are also reset synchronously, so that the locking rod 142 is in the state of being locked under the elastic force of the spring rod 144, thereby facilitating the subsequent locking operation of the fixing device 13, and improving the convenience of using the device.

[0072] The use method of the present application is as follows:

When the inner box body 12 returns to the initial height, the connecting rod 18 drives the rotating plate 133 to rotate and return to the horizontal state, the pushing stroke frame 131 is pushed to move towards the back of the cabinet 1, so that the bottom of the rotating plate 133 is in contact with the top surface of the cabinet 1, thereby the fixing device 13 plays a role in suspending and supporting the inner box body 12, so that the inner box body 12 is fixed, and then the locking rod 142 is reset under the elastic force of the spring rod 144, and is reinserted into the inside of the insertion hole 138 and locked. When the fixing device 13 is fixed to the inner box body 12 through the connection with the connecting rod 18, the first rotating device 93 is repeatedly pushed to move to one side, so that the internal ratchet of the rotating sleeve 931 is out of contact with the ratchet wheel 92 and is unlocked, and the second rotating device 94 is disassembled. At this time, the second rotating arm 6 is manually pulled again to rotate, thereby driving the bearing table 8 to move downwards, so that the top surface of the bearing table 8 is out of contact with the inner box body 12. At this time, the left and right transverse sliding plate 4 can be adjusted in position, so that it can disassemble and install different inner box bodies 12. After the locking rod 142 is inserted into the inside of the insertion hole 138 and locked, the pushing stroke frame 131 cannot be directly pulled from the outside at this time, so as to avoid the problem that the fixing device 13 is arranged on the outside and directly pulled by irrelevant personnel, thereby causing the inner box body 12 to be released. Meanwhile, when the operator disassembles, the operator can also avoid the problem that the operator pulls the wrong pushing stroke frame 131, thereby causing the inner box body 12 that is not lifted by the bearing table 8 to be incorrectly released. In addition, after the lifting of the inner box body 12 is completed, if the operator forgets to reset the fixing device 13, when the first rotating device 93 is reset and the second rotating device 94 is disassembled, the inner box body 12 will be inclined forward under the influence of the self-weight, thereby reminding the operator of the effect of the incomplete locking operation. The present application adopts two safety devices to ensure correct operation. The first safety device is that the rotating handle 932 drives the internal ratchet of the rotating sleeve 931 to be out of position and disengaged from the ratchet wheel 92 to be unlocked. The second safety device is that the pushing stroke frame 131 is pulled to make the rotating plate 133 out of contact with the top surface of the cabinet 1 to be unlocked. When both safety devices are unlocked, the operation of lowering the height of the inner box body 12 can be performed, and the pre-operation of unlocking the second safety device is that the rotating handle 932 drives the push rod 17. Therefore, the operator needs to unlock the first safety device to unlock the second safety device, thereby ensuring the correct sequence of operation. Meanwhile, when the inner box body 12 is lifted, the first rotating device 93 needs to be rotated and the handle 932 needs to be locked with the clamping seat 11. At this time, the internal ratchet of the rotating sleeve 931 can limit the ratchet wheel 92.Prevent the inner box 12 in the process of lifting adjustment device 9 appears the case of rotation, and the first rotation device 93 rotation, the top bar 16 and push rod 17 will also be reset, so that the locking rod 142 in the spring rod 144 under the action of elastic force in the state of locking, so as to facilitate the subsequent locking operation of the fixing device 13.
