Examples

Referring to fig. 1 to 5, the present invention provides an airtight steel door, which includes a door body 10 and a sealing assembly 20.

Wherein, door body portion 10 and seal assembly 20 cooperate, compare in traditional joint strip sealed have better airtight effect.

The door portion 10 includes an outer door frame 110, an inner door frame 120, and a door panel 130. The inner door frame 120 is fixedly arranged at the inner side of the outer door frame 110, and the inner door frame 120 and the outer door frame 110 are integrally formed; the door panel 130 is hingedly installed inside the outer door frame 110 in front of the inner door frame 120. The seal assembly 20 includes a bladder 210, an air inlet tube 220, and a gasket 240. The front side of the inner door frame 120 is provided with a square frame groove 121, the airbag 210 is arranged inside the square frame groove 121, the sealing gasket 240 is fixedly arranged on the front side of the inner door frame 120, and the sealing gasket 240 and the inner door frame 120 are fixed through gluing. The rear side of the airbag 210 is communicated with an air inlet pipe 220, the air inlet pipe 220 penetrates through the inner door frame 120, and the air inlet pipe 220 is provided with a one-way valve 230.

Air is injected into the air bag 210 inside the square groove 121 from the air inlet pipe 220 until the air bag 210 bulges out of the square groove 121, and the one-way valve 230 prevents the air inside the air bag 210 from being discharged outwards. When the door panel 130 is closed, the rear side of the door panel 130 contacts with the air bag 210 bulged from the inside of the square frame groove 121, and compared with the traditional sealing rubber strip, the sealing rubber strip has a better air-tight effect and reduces dust entering a room. When frequently used, additional gas may be supplied into the airbag 210 through the gas inlet pipe 220. The gasket 240 on the inner side of the door panel 130 can also provide a good sealing effect when the airbag 210 is short of gas, and can be used as an auxiliary seal.

In the above embodiment, the air pump 250 is installed at the rear side of the outer door frame 110, and an air outlet port of the air pump 250 is communicated with one end of the air inlet pipe 220 away from the air bag 210. The rear side of the bottom of the air bag 210 is communicated with an air overflow pipe 260, and the air overflow pipe 260 is provided with a pressure relief valve 270. The air pump 250 can rapidly supply air into the air bag 210, and when the air supply in the air bag 210 is over-pressure, the air can be discharged from the air overflow pipe 260 through the pressure release valve 270, so that the air bag 210 is prevented from being damaged by excessive air.

Further, the door portion 10 further includes an observation window 140, and the observation window 140 is mounted on the door panel 130; the observation window 140 is used to penetrate the condition of the inside of the door. The door portion 10 further includes a handle 150, and the handle 150 is mounted to the front surface of the door panel 130. The outer edges of the door panels 130 close to one side of the inner door frame 120 are all fixedly provided with sealing strips 280, and the sealing strips 280 are used for sealing when the lifting door panels 130 are in contact with the air bags 210. A door closer 160 is installed between the top of the door panel 130 and the outer door frame 110. Hinge 170 is provided between outer door frame 110 and door panel 130. The door closer 160 is provided so that the door panel 130 can automatically close the door panel 130.

It should be noted that the specific model specification of the air pump 250 needs to be determined by type selection according to the actual specification of the device, and the specific type selection calculation method adopts the prior art, so detailed description is omitted. The power supply of the air pump 250 and its principle will be clear to a person skilled in the art and will not be described in detail here.

The working principle of the airtight steel door is as follows: when the air bag is used, air is injected into the air bag 210 in the square groove 121 from the air inlet pipe 220 until the air bag 210 bulges out of the square groove 121, and the one-way valve 230 prevents the air in the air bag 210 from being discharged outwards. When the door panel 130 is closed, the rear side of the door panel 130 contacts with the air bag 210 bulged from the inside of the square frame groove 121, and compared with the traditional sealing rubber strip, the sealing rubber strip has a better air-tight effect and reduces dust entering a room. When frequently used, additional gas may be supplied to the interior of the airbag 210 through the gas inlet tube 220. The gasket 240 on the inner side of the door panel 130 can also provide a good sealing effect when the airbag 210 is short of gas, and can be used as an auxiliary seal. The air pump 250 can rapidly supply air into the air bag 210, and when the air supply in the air bag 210 is over-pressure, the air can be discharged from the air overflow pipe 260 through the relief valve 270, so that the air bag 210 is prevented from being damaged due to excessive air injection.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
