Use the technical scheme of this embodiment, the top of control box subassembly is provided with hook structure 30, when carrying out the equipment of control box subassembly, earlier make lid 20 hang on box base 10 through hook structure 30, realize the preliminary location of the two vertical direction, use hook structure 30 to make lid 20 rotate towards box base 10 as rotation center again, realize the lid of the two and close, lock lid 20 and box base 10 together through locking structure 40 at last, form the control box subassembly. When the control box assembly needs to be disassembled, the box base 10 and the box cover 20 are unlocked through the locking structure 40, and then the box cover 20 is rotated in a direction away from the box base 10 by taking the hook structure 30 as a rotation center. The assembling and disassembling process is simple, and operation of operators is facilitated. Therefore, the technical scheme of this embodiment can solve the comparatively complicated problem of operation when dismouting control box subassembly among the correlation technique effectively. Note that the box cover 20 is rotated in a certain rotation plane, and the rotation plane may intersect with the plane where the box base 10 is located, or may be parallel to the plane where the box base 10 is located. Preferably, the rotation plane of the box cover 20 intersects with the plane of the box base 10 and is perpendicular to each other.

As shown in fig. 5 to 9, the locking structure 40 includes a locking tongue 41 and a retaining member 42 disposed on the box cover 20 and a locking hole 43 disposed on the box base 10, the locking tongue 41 is rotatably disposed on the box cover 20, the locking tongue 41 has a locking position in backstop fit with the box base 10 and a dismounting position capable of passing through the locking hole 43, the retaining member 42 can apply an acting force to the locking tongue 41 to keep the locking tongue 41 at the locking position, wherein, in the process of mounting the box cover 20 on the box base 10, the locking tongue 41 is in abutting fit with the box base 10 and/or the locking hole 43 to overcome the acting force of the retaining member 42, so that the locking tongue 41 is switched from the locking position to the dismounting position to allow the locking tongue 41 to pass through the locking hole 43, and after the locking tongue 41 passes through the locking hole 43, the locking tongue 41 is switched from the dismounting position to the locking position by the acting force of the retaining member 42 to lock the box base 10 and the box cover 20; during the process of detaching the box cover 20 from the box base 10, the latch 41 is operated to switch from the locking position to the detaching position, so that the latch 41 passes through and leaves the lock hole 43 to unlock the box base 10 and the box cover 20.
