The power box comprises a box body, the box body comprises a box wall, a box door and a door lock structure, the door lock structure comprises a first lock rod which is arranged on the inner wall of the box door and can extend out of the box door upwards, a second lock rod which can stretch out of the box door downwards, a rotating shaft arranged on the inner wall of the box door, a rotating lock rod which is arranged on a rotating shaft and can be rotated to the outside of the side wall of the box door, and cranks which are arranged on the rotating shaft and are in point symmetry with the center point of the rotating shaft as the symmetric point, the first lock rod and the second lock rod are connected with the cranks through rotating connecting rods,the power box further comprises a first lock block, a second lock block and a third lock block which are arranged on the box wall, the first lock block is provided with a first lock hole matched withthe first lock rod, the second lock block is provided with a second lock hole matched with the second lock rod, and the third lock block is provided with a lock groove formed in the rotating path of the rotating lock rods. The door lock structure strength is good, the wind-resistance capacity is high, the lock effect is good, the power box is effectively suitable for the area with the large wind,and the beneficial effect of being convenient to lock is achieved.

Description

technical field [0001] The invention relates to the field of power equipment, in particular to a power box. Background technique [0002] The power distribution junction box is referred to as the power box, which is a kind of distribution box and the final equipment of the power distribution system. Closed or semi-closed metal cabinets. At present, the door lock mechanism of the power box generally achieves the effect of closing the door through a lock rod or a lock head. The structural strength is not very good, and the wind resistance is poor. In areas with strong winds, the locking effect is not very good. When it is opened under action, the electrical components in the box are prone to damage, such as a power box published by the application number CN201520908025.1. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a power box, the door lock has good structural strength, strong wind resistance, good locking...
