Preferably, the placing groove is formed by concave-down forming of the upper surface of the base, and a hollowed-out cover plate is buckled above the placing groove.

Preferably, a fork hole for inserting a fork of a forklift is formed between the two opposite side surfaces of the base, and the fork hole is completely separated from the upper side of the base.

Preferably, the box cover is a frustum-shaped shell which gradually increases from top to bottom. The box cover adopts a frustum-shaped shell, can adopt a cone frustum, a square frustum and the like, and is convenient for nesting and stacking the box cover in a structure with a small upper part and a big lower part.

Preferably, the box cover is a square frustum-shaped shell.

Preferably, the air exhaust hole is positioned in the center of the top surface of the box cover.

Preferably, a pre-tightening spring is arranged between the upper part of the elastic hook lock and the box cover, a pin shaft fixed on the box cover is arranged in the middle of the elastic hook lock, the lower part of the elastic hook lock is an inward bent hook head, the inner side surface of the hook head is a guide inclined plane, and the hook head is hooked and buckled on a hanging plate on the base.

The utility model discloses a seal box can lock automatically to utilize the check valve to bleed and realize that current leakproofness detects, utilize baroceptor to realize the long-time monitoring of incasement gas pressure.
