Description of the drawings
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the upper set of the utility model and the mounting structure schematic diagram trapped.
Specific implementation mode
As depicted in figs. 1 and 2, a kind of mining self-closing pedestrian's air door, it includes doorframe 1 and door leaf 2, further includes screw-casing group
Part, the sealing of Q types and damping rubber block, the screw-casing component are made of upper set 3,4, shaft 5 of trapping and compressed spring 6, door leaf 2
It is inlaid in doorframe 1, is fixed respectively at the position of two frame faces up and down of doorframe 1 and cover 3 on one, up and down the two of door leaf 2
One is fixed at the position of frame face respectively and traps 4, and the upper set 3 on the upper and lower side frame of doorframe 1 and door leaf 2 and traps 4 one by one
It is corresponding；A counterbore is offered on two frames up and down of door leaf 2；
Above set 3 is a column construction, and the upper end of the column construction is provided with a connection otic placode to both sides are radially projecting, and should
A stepped hole is offered in the middle part of the cylinder of column construction, big stepped hole is for being set with compressed spring 6, and small stepped hole is for wearing
If shaft 5；
It 4 is a cylindrical structure to trap, and the upper center of the cylindrical structure is provided with an overlap joint ear to both sides are radially projecting, and
A through-hole is offered in the middle part of the cylinder of the column construction, screw thread is provided in the through-hole；6 one end of compressed spring, which is stretched into, to be sleeved on
Set 3 big stepped hole in, other end apical grafting trap 4 upper end；Shaft 5 sequentially passes through the small stepped hole of set 3 and big
Stepped hole, be then passed through trap 4 through-hole after connect with the through hole whorl；Above the connection otic placode of set 3 and doorframe 1 are tight by bolt
Gu；Door leaf 2 is rotated relative to doorframe 1 with screw-casing component.
The center line that set 3 on two on two frames up and down of doorframe 1 is fixed on described in the utility model is straight at one
On line.Two be fixed on two frames up and down of door leaf 2 trap 4 center line point-blank, and upper set 3 with trap 4
Center line point-blank.The side being bonded is provided with damping rubber block with doorframe 1 in door leaf 2, it is close in door leaf 2
