As shown in fig. 1 and 2, the pressure container includes a container body 10, a sealing cover 20 covering an opening of the container body 10, the sealing cover 20 being hinged to an outer side of the container body 10 by a hinge support 30, so that the sealing cover 20 is mounted to the container body 10, and the side of the container body 10 is opened after the sealing cover 20 is opened, as in the operation of opening a door.
As shown in fig. 1 and 2, the present invention relates to a quick-opening structure of a pressure container, which includes a sealing cover 20 for sealing an opening of a container body 10 and a quick-opening assembly for pushing the sealing cover 20 to release or tightly cover the opening of the container body 10. Referring to fig. 2, the quick-opening door assembly includes a stopper groove 3 disposed at the mouth of the container body 10 and disposed at the outer edge of the sealing cover 20, a pressing rod assembly 1 disposed on the outer surface of the sealing cover 20, and a driving assembly 2 connected to the pressing rod assembly 1.
In this embodiment, as shown in fig. 3, the driving assembly 2 includes a rotating shaft 21 installed on an outer surface of the sealing cover 20 and a link assembly driven by the rotating shaft 21. The connecting rod component is connected with the pressure rod component 1. During operation, the rotating shaft 21 rotates to drive the connecting rod assembly to push the pressure rod assembly 1 outwards to enter the limiting groove 3 to compress the sealing cover 20 to the opening of the container body 10, and sealing of the container is achieved. Specifically speaking, the split rod 11 in the pressure rod assembly 1 enters the limiting groove 3 to press the sealing cover 20 to the opening of the container body 10, so as to seal the container. Or the rotating shaft 21 rotates reversely to drive the connecting rod assembly to pull the pressure rod assembly 1 inwards to exit the limiting groove 3, so that the pressure rod assembly 1 releases the sealing cover 20, and the sealing cover realizes quick opening of the door.
Among the above-mentioned technical scheme, when container body 10 needs to be sealed, with sealed lid 20 lid in container body 10's oral area, at this moment, sealed lid 20 has been in spacing groove 3, then expands through depression bar subassembly 1 for depression bar subassembly 1 also gets into spacing groove 3, because spacing groove 3 is to sealed lid 20 spacing in the axis direction, makes depression bar subassembly 1 compress tightly sealed lid 20 to container body 10's oral area, realizes container body's sealed. When the container body 10 needs to be opened, the driving assembly 2 is operated reversely, so that the pressure rod assembly 1 contracts, the pressure rod assembly 1 exits the limiting groove 3, the pressure applied by the pressure rod assembly 1 on the sealing cover 20 disappears, the sealing cover is loosened, and the sealing cover 20 can be opened quickly.
Among the above-mentioned technical scheme, at sealed operation and the quick in-process of opening of lid 20, all only through operating drive assembly 2 can, drive assembly 2 is last not to set up drive assembly such as screw rod, lead screw, among this technical scheme, realize the quick removal on a large scale of depression bar subassembly through link assembly, the rotation axis 21 is rotatory to be close to 90 angle and can be realized the expansion and the shrink of depression bar subassembly 1, easy operation is quick, can realize closing the door fast sealed and open the door soon, can realize quick frequent operation.
Among the above-mentioned technical scheme, the structure setting of opening the door soon is outside sealed lid, does not occupy the space of sealed lid radial direction in the space, and the effectual sealed range of opening and shutting of having avoided the increase realizes the miniaturization and the convenience of opening the door soon. Structurally, the structure of the sealing cover or the container body is not depended on, the sealing cover and the container body in any shape or structure can be opened quickly, and the adaptability is wide. For example, a rectangular or polygonal cylindrical container body or a sealing cover can adopt the quick-opening door structure in the technical scheme.
As shown in fig. 2, the groove width of the limiting groove 3 (the groove width refers to the width of the limiting groove in the axial direction of the sealing cover) is larger than the thickness of the sealing cover 20, so as to provide a space for the compression bar assembly 1 to enter the limiting groove 2 and compress the sealing cover 20. The outer diameter of the notch 33 of the limiting groove 3 far away from the container body 10 is not smaller than the outer diameter of the sealing cover 20, so that the sealing cover 20 can be directly pressed into or withdrawn from the limiting groove 3 conveniently.

The locking hole 42 is a blind hole, which does not affect the sealing of the sealing cover 20.
As shown in fig. 5, the sealing cover 20 is further provided with a safety limiting device 5, and the safety limiting device 5 includes a safety hole 51 formed in the sealing cover 20, a safety valve disposed in the safety hole 51, and a limiting hole 52 formed in the split rod 11 disposed outside the safety hole 51. After the split rod 11 is placed in the limiting groove 3 and the sealing cover 20 is pressed to seal, the limiting hole 52 is coaxial with the safety hole 51. The safety valve comprises a valve body 55 arranged in the safety hole 51 and a limiting rod 53 arranged in the valve body 55, and only a spring 54 is sleeved on the limiting rod 53. Under the action of high pressure in the container, the limiting rod 53 is ejected outwards, the spring 54 is pressed, and the limiting rod is inserted into the limiting hole 52 on the splitting rod, so that the limiting of the splitting rod 11 is realized, the splitting rod 11 is prevented from moving, and the operation of opening the sealing cover in a sealed container under the high-pressure state is avoided. When the pressure in the container disappears, the action and the air pressure on the limiting rod 53 disappear, the spring 54 resets, the limiting rod 53 exits from the limiting hole 52 on the split rod, the handle can be rotated through normal operation, the compression bar component 1 can be contracted, the compression bar component exits from the limiting groove, and the sealing cover can be opened quickly.
