Abstract

The invention discloses a packing container capable of rapidly sealing, locking and opening a case cover, solving the problem that the operation is complex and the consumed time is long when the case cover of the existing pressure-bearing sealed packing container is locked or opened. According to the packing container, a lower box (2) is movably provided with an upper box (1); hinged seats (4) are arranged on the outer side of the periphery of the box opening of the lower box in equal intervals; the hinged seats correspond to bolt seats (3); the top end of a U-shaped head handle (6) is hinged to the two ends of a hinged shaft (5); an upper hinge pin (12) is arranged between top ends of two parallel connecting plates (11); the bottom end of a connecting bolt (8) is hinged to the middle of the upper hinge pin (12); a bolt clearing hole (14) vertical to the axle wire of a cylinder is formed in a half-cylinder-shaped locking block (13) which is horizontally arranged; a screw of the connecting bolt (8) is movably buckled with a horizontal U-shaped groove in the bolt seat. The packing container can be rapidly and conveniently locked and opened without a tool.

Description

technical field [0001] The invention relates to a sealed packing box, in particular to a sealed packing box filled with a certain pressure of nitrogen gas to protect the products therein. Background technique [0002] The pressure-bearing sealed packaging box is composed of an upper box, a sealing ring and a lower box. It requires a certain pressure of nitrogen in the box to protect the products in the box. Therefore, the sealing effect is relatively high. The box body and the box cover of the existing pressure-bearing sealed packaging box are fixedly connected by multiple bolts, and the bolts and nuts are tightened or loosened one by one by using a wrench or professional tools to realize the locking or opening of the box cover of the packaging box. There are defects that locking or opening the box cover is cumbersome and time-consuming, and there are also fastening bolts and nuts that are easily damaged and affect the sealing effect of the box body. Contents of the inven...
