Description

TECHNICAL FIELD

[0001] The present application relates to a stage air box. BACKGROUND

[0002] The stage air box is a new type of packaging product for replacing transportation, which is generated to solve the problems of the traditional simple wooden box packaging and transportation, such as the ineffective protection of stage lamps and stage equipment during long-distance transportation and poor mobility.

[0003] The existing stage air box is mainly composed of a box body, a box cover and an aluminum frame. The aluminum frame is arranged at the opening edge of the box body and the box cover, and is connected with the box body and the box cover through a clamping groove and a protrusion. In this way, when the box body, the box cover or the aluminum frame is subjected to extrusion force, etc., the aluminum frame is easy to be separated from the box body or the box cover. The structure of the aluminum frame is that the cross section mainly includes a clamping part and a connecting part connected at one end of the clamping part, and a clamping groove for clamping a sealing ring is arranged on the end face of the connecting part. In order to improve the strength of the aluminum frame, a protruding rib extending inward is arranged on the inner side of the aluminum frame, and a bracket is installed on the two opposite protruding ribs. In the air box with such a structure, in order to improve the strength of the aluminum frame, the protruding rib is arranged along the inner side of the aluminum frame. In this way, the opening of the entire air box is smaller than the size of the box body due to the existence of the protruding rib. When the stage equipment is placed, the size of the stage equipment must be determined according to the size of the protruding rib. After the stage equipment is placed in the box body, part of the space in the box body is not used, which causes the waste of space. Moreover, in the case of stage equipment of the same size, the size of the box body is relatively large, so that it is inconvenient to carry and the transportation cost is high. In addition, the bracket is installed on the protruding rib, and the bracket hole is arranged on the bracket. In order to better place the stage equipment, a through hole corresponding to the bracket hole needs to be formed on the protruding rib. In this way, when the bracket is installed, the through hole and the bracket hole need to be corresponding in position, which requires high installation and processing requirements. Furthermore, in the above structure, the sealing ring is arranged between the two aluminum frames in the vertical direction, and the sealing glue is connected to one of the aluminum frames by glue. In this way, if the glue is too little, the connecting part of the sealing ring is firm, and if the glue is too much, the glue may overflow, which causes the appearance to be not beautiful. SUMMARY
