Abstract

The invention relates to a sealed hinged air pressure box, which belongs to the technical field of power supply equipment boxes, and solves the problem that the existing box body cannot be opened and closed on the basis of the box cover, and ensures that the box cover device is effective and reliable and has high sealing performance to meet the requirements. question. The invention comprises: a box body, a box cover and a rotary hinge; one side of the box body and the box cover is connected by a rotary hinge; the opposite sides of the box cover connected to the side are respectively provided with gas springs connected with the box body; Vertical to the side; the rotary hinge includes an upper hinge, a lower hinge and a hinge pin; the fixed end of the upper hinge is fixedly connected with the box cover, the fixed end of the lower hinge is fixedly connected with the box body, and the hinge pin passes through the free end of the upper hinge and the free end of the lower hinge; the free end of the lower hinge is bent toward the outside of the box. The invention realizes rapid opening and reliable closing, has small volume, simple structure, convenient operation, effective reliability and high sealing performance.

Description

technical field [0001] The invention relates to the technical field of power equipment boxes, in particular to a sealed hinged air pressure box. Background technique [0002] The box cover device of the standard power supply equipment box is generally a fixed lock accessory (pin shaft, pressure riveting screw, etc. to realize the opening and closing of the box cover, and its reliability and sealing performance are poor. For non-standard power supply equipment boxes, box The opening method of the cover is usually designed as a rotary opening. When the locking screw or the pressure plate is loosened, the door will be supported along the hinge of the box cover under the action of the gas spring. In some cases that require effective reliability and high sealing performance For extremely high special occasions, due to limited space, it is necessary to design a hinged air pressure box cover device with small volume, simple structure and convenient operation to ensure the effective...
