Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
In the description of the present invention, it should be noted that the terms "inside", "outside", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
As shown in fig. 1, 2 and 3, the air-bag type airtight door of the present invention includes a door frame 10, and a door body 12 pivotally installed on the door frame 10. Door frame 10 is made by metal section bar, has the cavity that is used for the line in the door frame 10, and it can realize gaseous and electric wire and hide the line, and is whole neatly more and pleasing to the eye.
The door lock further comprises an electromagnetic lock 14 for locking the door body 12 and the doorframe 10, a control switch 16 is arranged on the doorframe 10, and the electromagnetic lock 14 is electrically connected with the control switch 16.
The door body 12 is provided with a front surface, a back surface and four side surfaces, grooves 18 are formed in the four side surfaces of the door body 12, all the grooves 18 are communicated with each other, and an annular air bag 20 is sleeved in the grooves 18. The air bag 20 is communicated with an air pipe 22, an electronic barometer (not shown) is arranged on the air pipe 22, the air pipe 22 is communicated with an electric control inflation and deflation valve (not shown), the electric control inflation and deflation valve is communicated with an inflator pump (not shown) or a high-pressure air source, and the control switch 16 is electrically connected with the electric control inflation and deflation valve and the electronic barometer.
The cross section of the air bag 20 comprises a plate-shaped base 24, an O-shaped bag body 26 arranged on the base 24 and a sealing strip 28 arranged on the bag body 26, wherein the cross section of the sealing strip 28 is W-shaped, and the base 24, the bag body 26 and the sealing strip 28 are integrally formed by silicon rubber.
Four angles of the door body 12 are arc-shaped, four angles of the door frame 10 are arc-shaped which are concentric with four angles of the door body 12 respectively, so that the air bag 20 at the corner is smooth in transition, the service life of the air bag 20 is prolonged, and the situation that insufficient air inflation at the sharp corner is not tight in sealing is avoided.
