The unfolding assembly includes two T-shaped fixed cover plates 3, two movable side plates 5 and a front box plate 8;

[0027] The unfolding assembly further includes a plurality of fixed blocks 2, and the plurality of fixed blocks 2 are respectively rotatably connected to the corresponding movable side plates 5. The two T-shaped fixed cover plates 3 are respectively fixedly connected to the upper and lower sides of the front surface of the plug-in box installation backplane 1. One end of the movable side plate 5 away from the plug-in box installation backplane 1 is hinged to the front box plate 8 through a hinge;

[0028] Two splicing quick-release components arranged in a mirror image are arranged on the front box plate 8, and the splicing quick-release components are used to connect multiple components of the unfolding assembly. The splicing quick-release components include a first groove 6, a second groove 7, a rotating shaft 10, a hook plate 11, a worm gear 12 and a worm 15.

[0029] Furthermore, the splicing quick-release component further includes a rotating shaft fixing seat 9, the rotating shaft fixing seat 9 is fixedly connected to the front box plate 8, the rotating shaft 10 is rotatably connected to the rotating shaft fixing seat 9, the hook plate 11 is fixedly sleeved at one end of the rotating shaft 10, and the worm gear 12 is fixedly sleeved at the other end of the rotating shaft 10.

[0030] Further, the first groove 6 is opened at the front end of the corresponding movable side plate 5, the second groove 7 is opened at a position on the outer surface of the vertical plate of the T-shaped fixed cover plate 3 corresponding to the first groove 6, and the second groove 7 is also opened at a position on the outer surface of the front box plate 8 corresponding to the second groove 7.

[0031] Further, one end of the hook plate 11 away from the rotating shaft 10 extends into the first groove 6 from the two second grooves 7, the hook portion of the hook plate 11 is adapted to the second groove 7, and the worm 15 is meshed and connected with the worm gear 12.

[0034] During use, place the handle on the handle 16, manually rotate the anti-slip rotating sleeve 17, and the anti-slip rotating sleeve 17 can drive the worms 15 on the two splicing quick-release components to rotate through the long shaft 14, so that the worm 15 can drive the worm gear 12 to rotate. The rotating worm gear 12 drives the hook plate 11 to rotate a small angle through the rotating shaft 10, so that the hook plate 11 can be disengaged from the edge position of the second groove 7. At this time, pull the handle 16, and the front box plate 8 can be rotated open, and at this time, the two movable side plates 5 can also be rotated outwards without restriction, so that the circuit breaker and its connecting wires on the plug-in box mounting back plate 1 can be more clearly presented, thus facilitating the maintenance personnel to troubleshoot and perform daily maintenance, improving work efficiency, and avoiding the problems in the traditional plug-in box during maintenance, such as its space being closed, the operable space being narrow, and the field of vision being limited, which is not conducive to the maintenance operation of the maintenance personnel.

[0035] Due to the self-locking property of the meshing of the worm gear 12 and the worm 15 adopted by the set splicing quick-release component, the opening and closing of the hook plate 11 can be effectively and stably controlled, avoiding the problem that the hook plate 11 is unlocked due to external shaking, resulting in the circuit breaker on the plug-in box mounting back plate 1 being exposed to the outside and not being effectively protected.

[0036] Working principle: When in use, place the handle on the handle 16 and manually rotate the anti-slip sleeve 17. The anti-slip sleeve 17 can drive the worm 15 on the two splicing quick-release components to rotate through the long shaft 14, so that the worm 15 can drive the worm gear 12 to rotate. The rotating worm gear 12 drives the hook plate 11 to rotate a small angle through the rotating shaft 10, so that the hook plate 11 can disengage from the edge position of the second groove 7. At this time, pull the handle 16, and the front box plate 8 can be rotated open. And at this time, the two movable side plates 5 are no longer restricted and can also be rotated outwards, so that the circuit breaker and its connecting wires on the plug-in box mounting back plate 1 can be presented more obviously.
