Description

Technical Field

[0001] The utility model relates to the field of fire fighting equipment, in particular to a connection structure of a box body and a cover body of a fire fighting box. Background Art

[0002] A fire extinguisher box can be a box used to store and protect electronic equipment such as circuit boards and emergency power supplies of fire emergency evacuation indication systems. It can control fire emergency lighting in public buildings and provide the correct route for personnel escape and fire rescue when a disaster occurs.

[0003] The existing fire extinguisher box is composed of a box body and a cover body, and connectors are assembled on the sides of the box body and the cover body. The box body and the cover body are connected to each other and cannot be separated through the connector, and the cover body can be selected with the connector as the axis to perform opening or closing operations. Therefore, the connector is an indispensable accessory for fire extinguishers.

[0004] The existing connecting parts are composed of three parts, among which, a box part connected to the box body, a cover part connected to the cover body and a rotating shaft arranged between the box part and the cover part. The box part is provided with an extension part extending to the side of the cover body, the cover part surrounds the extension part, and is fixed by the rotating shaft passing through the cover part and the extension part. In order to ensure that the cover part and the cover part will not be separated, the rotating shaft will be deformed at both ends by stamping after being assembled on the box part and the cover part. This structure makes the processing time of the connecting parts too long, resulting in an increase in product cost; in order to facilitate production, the existing connecting parts are all processed and then installed on the fire extinguishing box, but since some fire extinguishing boxes are very large in size, in order to facilitate the assembly of fire extinguishing boxes, the fire extinguishing boxes are all assembled flat on the assembly line, resulting in the cover body and the box body being assembled. The cover body can only be lifted up for assembly, which is extremely inconvenient; when assembling the accessories inside the box body, the cover body needs to be opened, and opening the cover body in a flat manner will cause the sides of the box body and the cover body to be subjected to excessive force, thereby causing deformation, resulting in product damage.
