Because the controller 5 comprises the inflation and decompression valve and the deflation valve, the gas pressure in the sealing element 4 can be conveniently controlled, and when the gas pressure in the sealing element 4 needs to be enhanced, the inflation and decompression valve can be opened, the deflation valve can be closed, and the sealing element 4 can be inflated through a gas source. The inflation pressure reducing valve can reduce the pressure of gas entering the sealing element 4, the gas source is prevented from filling the sealing element 4 with too large gas pressure, the control of the gas pressure inside the sealing element 4 is conveniently realized, and the sealing element 4 is effectively protected.
When the sealing element 4 is not needed to be sealed, the inflation and pressure reduction valve can be closed, the air release valve is opened, and the sealing element 4 is released from the air release valve, so that the internal pressure of the sealing element 4 is reduced, and the sealing between the door body 1 and the door frame 7 is not formed any more.
Preferably, the sealing groove 2 is arranged on the door body 1, the sealing strip 3 is arranged on the door frame 7, and a circumferential annular seal is formed between the door body 1 and the door frame 7 through the sealing piece 4. When the external gas got into the clearance department of door body 1 and door frame 7, because the sealing action of sealing member 4 and sealing strip 3, these gases are blockked in the space of sealing member 4 periphery, can't continue to enter into indoorly through door body 1, consequently can form more comprehensive effectual protection.
The sealing element 4 can be arranged on the inner side surface of the door body 1, and also can be arranged on the outer peripheral surface between the inner side surface and the outer side surface of the door body 1, so that the sealing fit between the door body 1 and the door frame 7 in four directions of up, down, left and right is realized, and the annular sealing effect is formed.
Of course, the sealing members 4 may be provided on the inner side surface and the upper and lower side surfaces of the door body 1, or on the inner side surface and the left and right side surfaces, as long as an annular sealing barrier zone can be formed between the door body 1 and the door frame 7.
In this embodiment, when the sealing member 4 is in a natural state, both opposite sides of the sealing member 4 are bent toward the inner cavity. Because two relative sides of sealing member 4 are crooked to the inner chamber, consequently can be so that sealing member 4 possess bigger volume, have bigger volume under the inflation state, can with realize more effective sealed cooperation between sealing strip 3, simultaneously when sealing member 4 is not inflated, two sides of sealing member 4 can be like inboard crooked, can not increase the volume of sealing member 4 and occupy, structural design is more reasonable, has effectively improved the volume ratio of sealing member 4 under aerifing and the uninflated state.
Preferably, in the present embodiment, the cavity of the sealing member 4 has an i-shaped cross section.
The two sides of the sealing element 4 can also be designed in a V-shape or W-shape etc.
In the present embodiment, the side of the seal 4 facing the weatherstrip 3 is provided with a bead 6 protruding toward the weatherstrip 3. After inflation of sealing member 4, the sand grip 6 can be at first with realize the contact between sealing strip 3, when the pressure in sealing member 4 continues to increase, sand grip 6 can be under the gas pressure effect in sealing member 4, imbed in sealing strip 3 to make and form better effectual sealed effect between sealing member 4 and the sealing strip 3.
Preferably, the protruding strips 6 are multiple and arranged at intervals in a zigzag manner, so that a multi-layer embedded seal can be formed between the sealing element 4 and the sealing strip 3, and the sealing protection effect is further improved. The cross section of the convex strip 6 can be rectangular, trapezoidal, triangular or circular arc.
Preferably, the sealing element 4 and the sealing strip 3 are both made of elastic materials, and the sealing matching effect between the sealing element 4 and the sealing strip 3 can be further improved by utilizing the elastic deformation effect of the sealing element 4 and the sealing strip 3.
Preferably, the weather strip 3 is bonded to the doorframe 7. Bond sealing strip 3 on door frame 7, can make sealing strip 3 and door frame 7 bond as an organic wholely, can make the material of door frame 7 itself unrestricted simultaneously, adopt the door frame 7 homoenergetic that various different materials made to realize good sealed cooperation relation between 3 with sealing strip, the structure is simpler, and the cost is lower, has increased the material optional scope of door frame 7, can follow cost and performance and carry out whole consideration in the aspect of selecting in the material of door frame 7, can obtain better price/performance ratio.
The sealing element 4 is bonded at the bottom of the sealing groove 2, and the sealing element 4 is expanded and extended out from the opening of the sealing groove 2 after being inflated, so that the sealing element 4 is bonded at the bottom of the sealing groove 2, the expansion deformation of the sealing element 4 cannot be influenced, the inflation expansion deformation capacity of the sealing element 4 can be more fully utilized, and the performance utilization is more fully realized.
Preferably, the door body 1 is provided with an annular sealing member 4 and an annular sealing strip 3, the sealing member 4 and the sealing strip 3 form a zigzag structure, the sealing strip 3 is arranged on the door frame 7 at a position corresponding to the sealing member 4 on the door body 1, and the sealing member 4 is arranged at a position corresponding to the sealing strip 3 on the door body 1. In this embodiment, the door body 1 is provided with the sealing member 4 and the sealing strip 3, and the door frame 7 is provided with the sealing strip 3 and the sealing member 4, respectively, wherein the sealing strip 3 on the door frame 7 is arranged corresponding to the sealing member 4 on the door body 1, and the sealing member 4 on the door frame 7 is arranged corresponding to the sealing strip 3 on the door body 1. Through the complementary structure matching, a complementary sealing structure can be formed between the door body 1 and the door frame 7, and the sealing performance between the door body 1 and the door frame 7 is further improved.
