Detailed Description
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, and it should be understood that the preferred embodiments are described herein for purposes of illustration and explanation, and not limitation.
As shown in fig. 1, 2 and 3, the integrated gangway ladder door sealing mechanism includes an upper door body 1 and a lower door body 2, a sealing assembly 3 is arranged between a front leaf of the upper door body 1 and a front leaf of the lower door body 2, the sealing assembly 3 includes a front sealing member 21 and a rear sealing member 32, the front sealing member 31 is respectively attached to the lower door body 2 and the rear sealing member 32, and the rear sealing member 32 is respectively attached to the front sealing member 31 and the upper door body 1, such that sealing between the upper door body 1 and the lower door body 2 is achieved through the sealing assembly 3, and a manner of attaching and sealing the two sealing members 21 to the upper door body 1 and the lower door body 2 is adopted herein, compared with a sealing manner of one sealing member, which can not only improve sealing performance in structural design, but also save material, reduce weight, and improve safety between the upper door body 1 and the lower door body 2, the phenomena of collision damage and the like cannot easily occur.
Specifically, the top of the front leaf of the lower door body 2 extends upward to form a first attaching portion 21, the first attaching portion 21 attaches to the front sealing member 31, the top of the front sealing member 31 extends out of the first attaching portion 21 and is obliquely and upwardly formed with a flow guide portion 211, the inner cross-section of the front sealing member 31 is circular and is provided with a first through hole 311, the outer cross-section of the rear sealing member 32 is also circular and is provided with a second through hole 321, the second through hole 321 is located on the outer side of the rear sealing member 32 and horizontally attaches to the first through hole 311, so that the external gas can firstly pass through the flow guide portion 211 and then reaches the outer portions of the first through hole 311 and the second through hole 321, namely a V-shaped portion formed between the first through hole 311 and the second through hole 321, and therefore, the sealing between the upper door body 1 and the lower door body 2 is realized through mutual extrusion between the first through hole 311 and the second through hole 321, and the sealing structure of a common sealing member is realized, this design improves sealed effect through contacting each other and two sealing members of mutual extrusion, simultaneously, the design of two through-holes can save material, reduce weight on the one hand, and on the other hand can guarantee to have certain extrusion space when receiving great atmospheric pressure, can not open the door body 1 and cause gas leakage with lower door body 2 by the bullet once.
