Sealing box and box body sealing structure thereof

Abstract

The invention provides a box body sealing structure. The box body sealing structure comprises a box body, a box cover and a seal ring, wherein the box body is covered with the box cover, and the seal ring is arranged on the junction surface of the box body and the box cover. The box body is matched with the box cover through an annular groove and an annular flange, the seal ring is arranged in the annular groove, and the annular flange is connected into the annular groove in a mortise joint mode and squeezes the seal ring. The annular groove is formed in the box cover or the box body, and the annular flange is arranged on the box body or the box cover. An annular protrusion which abuts against the bottom of the seal ring is further arranged on the annular flange, the cross section of the annular protrusion is in a semicircular shape, chamfers are arranged on the annular groove and the annular flange respectively, and the bottom of the annular groove is in an arc shape. The sealing structure is simple in structure and good in sealing performance, and the problem that the sealing effect is not good due to the fact that dislocation of the junction surface occurs when the box body is covered with the box cover is effectively solved. The invention further provides a sealing box. The sealing box comprises the box body and the box cover, the sealing structure is adopted between the box body and the box cover, and the box body is fixedly connected with the box cover in a mode that hooks are arrange on the periphery.

Description

technical field [0001] The invention relates to the field of sealing technology, in particular to a box sealing structure and a sealing box with the structure. Background technique [0002] The sealing box is generally designed with a sealing groove on the joint surface of the box cover or the box body, the sealing ring is placed in the sealing groove, and the box body or the box cover squeezes the sealing ring to achieve the sealing effect. In many cases, the box cover and the box body are made of plastic, which will deform after a long time. When the box cover is closed on the box body, it is easy to have the problem of misalignment and deviation of the joint surface, resulting in insufficient extrusion of the sealing ring, resulting in a tight seal. The box is not well sealed. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a box body sealing structure with simple structure and good sealing ...
