Embodiment Construction

[0008] Below in conjunction with accompanying drawing, the present invention is further described: during use, the rotating manual gear turntable 2 on the protective door 1 can drive the crossbar 4 with the rotating teeth, drive the horizontal movable link bar 6, and then convert it into a vertical link bar 7 by reversing the connecting bar 7. In the vertical direction, move the vertical movable link bar 8 to drive the locking bolt 9 up and down, and the left and right two locking bolts 9 are connected to a linkage cross bar 16 with a positioning pin in the middle, and the linkage cross bar with the positioning pin has a left positioning pin and the right side positioning bolt 18, the right side positioning bolt 18 moves up and down in the right-side curved attenuation chute 17, and the left and right two curved attenuation chutes connect the lifting link 15 to realize the sealing of the ground beam 11. Up and down, the manual gear turntable 2 can rotate under the positioning o...

Abstract

The invention provides a sealed ground beam. The sealed ground beam is composed of a protective door, a manual gear rotating table, a rotating table fixed shaft, a cross rod with rotating teeth, horizontal fixed riveting grooves, transverse movable linking bars, reversing connecting bars, vertical movable linking bars, vertical fixed riveting grooves, latching bolts, a linkage cross rod with positioning bolts, an amplitude reduction chute with radian, a movable linking piece and a sealed ground beam body. According to the sealed ground beam, influences of the sealed ground beam body to a channel can be avoided, meanwhile, the ground beam body can be protected from being worn, sealing effects can be improved, and the protective door with the sealed ground beam body can be used for occasions where requirements on protection levels are high, such as headquarters, funk holes and airplane shelters in wars.

Description

technical field [0001] The invention relates to a protective door structure, in particular to a sealed ground beam structure of the protective door. Background technique [0002] There are many kinds of protective doors at present, which can prevent biochemical poisonous gas, and must be sealed. But most of the protective doors with airtightness at present have a ground beam structure underground, which protrudes from the ground when opened, which is not conducive to automobile driving, and long-term wear and tear will also reduce the airtight performance. Contents of the invention [0003] The invention provides a sealed ground beam that can be opened together with a door. [0004] The technical solution is as follows: [0005] A sealed ground beam is characterized in that it consists of a protective door, a manual gear turntable, a turntable fixed shaft, a horizontal bar with rotating teeth, a horizontal fixed riveting groove, a horizontal movable link bar, a reversing...
