Abstract
The utility model relates to a sealing device. The sealing device comprises a container body and a container door, and further comprises a sealing ring, a door hook plate, a door hook pin, a compressed air inlet and exhaust opening and a hook pin plate, the sealing ring, the door hook plate, the door hook pin and the compressed air inlet and exhaust opening are arranged on the container body, and the hook pin plate is arranged on the container door. When the container door is closed, the door hook plate is hooked on the outer surface of the container door, the hook pin plate hooks the door hook pin, the sealing ring abuts against the container door by means of the pushing force effect of compressed air entering the compressed air inlet and exhaust opening, and therefore the container door is tightly attached to the door hook plate. When the container door is opened, the compressed air acting on the sealing ring is pumped out through the compressed air inlet and exhaust opening, the sealing ring resets to the initial position, and therefore the container door is in the movable opening state. The sealing device can achieve reliable sealing between the container door and the container body, and has the advantages that use is safe, the door can be conveniently opened and closed, and the service life is long.

Further, be provided with the seal groove arranging along its opening end on described container body all over the body, described seal ring is placed in sealing groove, and described pressurized gas enters row mouthful and is connected with sealing groove.
Further, the opening end of described container body is provided with flange, and described seal groove is opened on this flange.
Further, described door hook plate has several, is separately positioned on upside and left and right two sides of the opening end of described container body.
Further, described gate stop pin has several, is arranged on the downside of the opening end of described container body; Described hook pin plate has and the corresponding quantity of gate stop pin, and is arranged on the downside of described container door.
Preferably, described container body and container door are roughly rectangular.
Further, described seal ring comprises elastic wall and the air cavity being surrounded by elastic wall, and described air cavity enters from described pressurized gas the pressurized gas that Pai Kou passes in order to receive.
Preferably, described seal ring roughly takes the shape of the letter U.
Further, the folding of described container door is moved in same plane.
Further, on described container body, be provided with suction valve and outlet valve.
Compared with prior art, the utlity model has following advantage:
First, the utility model seal arrangement is when container door is closed, by passing into pressurized gas to seal ring applied thrust, make it hold out against container door, can realize the reliable sealing between container door and container body, avoid container body generation leakage phenomenon, improve the Security of using; Also can reduce the requirement to machining accuracy of container door and container body, convenient manufacture simultaneously.
Secondly, while opening the door, extract pressurized gas out, seal ring gets back to initial position, can not affect the unlatching of container door and close next time, so switch gate is all very convenient.
Moreover container door adopts and to move up and down retractable structure, not easy to wear, long service life, and can improve the space availability ratio of product.

Embodiment
The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.
As shown in Figures 1 to 6, a kind of seal arrangement described in the present embodiment, comprises container body 1 and container door 2, is provided with suction valve 3 and outlet valve 4 on container body 1.
Also comprise that the seal ring 5, door hook plate 6, gate stop pin 7, the pressurized gas that are arranged on container body 1 enter row's mouth 8 and be arranged on the hook pin plate 9 in container door 2.When container door 2 is closed, door hook plate 6 hooks are in the outer surface of container door 2, hook pin plate 9 hooks gate stop pin 7 by the dog hole 91 arranging on it, seal ring 5 withstands container door 2 by entering the thrust of row's mouthful 8 pressurized gass that pass into from pressurized gas, make container door 2 be close to door hook plate 6, thereby the sealing that realizes 1 of container door 2 and container body is with fixing.When container door 2 is opened, by pressurized gas, enter row's mouth 8 pressurized gas that acts on seal ring 5 is extracted out, make seal ring 5 be reset to initial position, and then make container door 2 in removable open mode.
Further, for the ease of the installation setting of seal ring 5, the opening end of container body 1 is welded with flange 10, offers the seal groove 11 arranging along container body opening end on flange 10 all over the body, and seal ring 5 is placed in sealing groove 11.Meanwhile, pressurized gas enters row's mouth 8 and is connected with sealing groove 11, so that enter row's mouthful 8 pressurized gass that pass into from pressurized gas, can enter 11 pairs of seal ring 5 applied thrusts of seal groove.
Preferably, container body 1 and container door 2 are roughly rectangular, can certainly be designed to according to actual needs other shape.Door hook plate 6 has several, is separately positioned on upside and left and right two sides of the opening end of container body 1.Gate stop pin 7 has several, is arranged on the downside of the opening end of container body 1; Hook pin plate 9 has and the corresponding quantity of gate stop pin 7, and is arranged on the downside of container door 2.
Preferably, for the ease of seal ring 5, under compressed-air actuated thrust, better make sealing action or resiliently deformable, seal ring 5 roughly takes the shape of the letter U, it comprises elastic wall and the air cavity being surrounded by elastic wall, and described air cavity enters row's mouthful 8 pressurized gass that pass in order to receive from pressurized gas.
Preferably, container door 2 adopts the retractable structure that moves up and down in same plane.Select, container door 2 also can adopt the retractable structure that moves left and right in same plane again.
As mentioned above, described in the present embodiment, the sealing principle of seal arrangement is:
1. close the door: when container door 2 is closed to while closing the door precalculated position, enter row mouthfuls 8 pass into pressurized gas (pressure of pressurized gas should be greater than the pressure in container body) from pressurized gas, pressurized gas is released seal ring 5 to withstand container door 2, makes door be close to door hook plate 6.When container passes into pressed gas by suction valve 3, because the compression pressure of seal groove 11 is greater than the pressure in container, the gas in container just can not let out by seal ring 5.
2. open the door: after the pressure in container is discharged by outlet valve 4, can enter row's mouth 8, the pressurized gas in seal groove 11 be extracted out and form negative pressure by pressurized gas, make in seal ring 5 indentation grooves, leave container door, door can be reciprocatingly slided between the gap of flange 10 and 6 formations of door hook plate, open the door and door-closing operation.
In addition, the all right design safety interlock of the utility model, for example can pass through electrical apparatus control system, control when door also pass to close the door precalculated position time, seal ring can not be inflated, gapped between door and seal ring, in container, can not boost, can prevent that Men Wei from shutting the container explosion accident of boosting and occurring.
As described above, it is only this novel preferred embodiment, when not limiting with this scope of this novel enforcement, the simple equivalence of in every case doing according to this novel claim and novel description changes and modifies, and all still belongs in the scope that this new patent contains.
