DETAILED DESCRIPTION

[0020] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0022] In the embodiment of the present invention, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0023] Reference example Figures 1 to 3 , an explosion-proof and corrosion-proof control box, comprising a box body 1 and a box cover 2. A liftable first push rod 3 is provided on one side of the box body 1, and a rotatable second push rod 4 is provided on one end of the first push rod 3. The second push rod 4 is hinged to the box cover 2. When the rotation position of the first push rod 3 and the second push rod 4 is higher than the top of the box body 1, the box cover 2 is rotated to make the box cover 2 and the box body 1 butt against each other, and the box cover 2 is made higher than the top of the box body 1 by the first push rod 3, and the box cover 2 is moved toward one side of the box body 1 by the second push rod 4, and the box cover 2 and the box body 1 are butted against each other, so that the box cover 2 is fixed in the position after the movement, so that the entrance of the box body 1 is completely exposed to the sight of the maintenance personnel, which not only improves the operable space and field of vision, but also prevents dust from adhering to the sealing strip 22. At the same time, it also prevents the maintenance personnel from rubbing against the sealing strip 22, thereby overcoming the problems mentioned in the background technology;
