[0046] See also Figure 1-Figure 13A two-way opening tunnel air door includes a door frame 1, which is fixed on the inner wall of the tunnel. A first door leaf 20 and a second door leaf 21 are hinged on two side rods 19 of the door frame 1, and the tops of the side walls of the first door leaf 20 and the second door leaf 21 are connected with connecting parts 2, and the two connecting parts 2 are located on the same side of the door frame 1, and a connecting rod 3 is rotatably connected between the tops of the two connecting parts 2, one of the connecting parts 2 is L-shaped, and the L-shaped connecting part 2 is located on the top of the side wall of the second door leaf 21 in the closing direction, and the other connecting part 2 is connected to the top of the side wall of the first door leaf 20 in the opening direction.

[0047] When the damper needs to be opened, the first door leaf 20 is pulled. When the first door leaf 20 is started, the connecting rod 3 is pulled. The connecting rod 3 pulls the L-shaped connecting piece 2, so that the second door leaf 21 opens in the other direction. Therefore, only one door leaf needs to be driven to open the two door leaves in both directions at the same time.

[0048] The first door leaf 20 and the second door leaf 21 are hinged to the side rod 19 of the door frame 1 through the first hinge 22 and the second hinge 23, see Figure 5 and Figure 6 The first hinge comprises a first fixing plate 24, which is fixed to the side wall of the side rod 19 of the door frame 1, and a first arc-shaped plate 25 facing the inner side of the door frame 1 is connected to the side wall of the first fixing plate 24, and a first connecting shaft 26 is connected to the side wall of the first arc-shaped plate 25 away from the first fixing plate 24, and the first connecting shaft 26 is hollow inside and has an opening at the top; the second hinge comprises a second fixing plate 27, which is fixed to the side wall of the door leaf, and a second arc-shaped plate 28 facing the outer side is connected to the side wall of the second fixing plate 27, and a second connecting shaft 29 is connected to the side wall of the second arc-shaped plate 28 away from the first fixing plate 24; two first hinges can be connected to the two side rods 19 of the door frame 1 respectively, and two second hinges can be connected to the side walls of the first door leaf 20 and the second door leaf 21 respectively, and the positions correspond to the first hinges respectively; during installation, the first door leaf 20 and the second door leaf 21 are hoisted, and the second connecting shaft 29 is inserted into the first connecting shaft 26, see Fig.13 This hinge method is within the cross section of the door frame side rod after the door leaf is opened.

[0049] Also, see Fig.10 The second fixing plate 27 can also be L-shaped and directly connected to the left and front side walls of the door leaf. Then, the second connecting shaft 29 is welded to the second fixing plate 27 on the left side wall. When connecting, the second connecting shaft 29 is inserted into the first connecting shaft 26. Fig.11 This hinge method does not locate inside the door frame side rod after the door leaf is opened, and does not occupy the door frame interface.

[0050] Furthermore, the top rods of the door frame 1 include: a first top rod 30, a second top rod 31 and a third top rod 32; one end of the first top rod 30 and the third top rod 32 are respectively connected to the tops of the two side rods of the door frame 1; the other ends of the first top rod 30 and the third top rod 32 are respectively connected to the opposite side walls of the second top rod 31; when the two door leaves are closed, a part is located directly below the second top rod 31, and a part of the first door leaf 20 and the second door leaf 21 close to the side rod of the door frame 1 is staggered with the first top rod 30 and the third top rod 32; when disassembling, the connecting rod 3 is first disassembled, and then only the first door leaf 20 and the second door leaf 21 need to be rotated by a certain angle, for example 30°, at which time the first door leaf 20 and the second door leaf 21 are completely staggered with the top rod, and then the first door leaf 20 and the second door leaf 21 are lifted upwards, so that the first door leaf 20 and the second door leaf 21 can be pulled out from the first connecting shaft 26 to complete the disassembly, making the installation and disassembly of the door leaves more convenient.

[0051] In addition, the length of the second push rod 31 may be equal to the length of the first push rod 30 and the third push rod 32 , or may be smaller than or larger than the length of the first push rod 30 and the third push rod 32 .

[0052] Furthermore, a mounting plate 18 is fixed on the side rod 19 of the door frame, a cylinder is movably hinged on the mounting plate 18, a first slide rail 5 is connected to the side wall in the opening direction of the first door leaf 20 or the second door leaf 21, a slider 6 is slidably connected in the first slide rail 5, and a piston rod 4 of the cylinder is movably hinged to the slider 6; a plug hole 7 is provided on the inner wall of the first slide rail 5, and a safety device is provided on the slider 6, the safety device comprising: a sleeve 8 connected to the side wall of the slider 6, a through hole is provided on the slider 6, and the through hole and the sleeve 8 are connected. Corresponding to the position, a locking rod 9 is movably connected in the sleeve 8, a first limit plate 10 is connected to the inner wall of the sleeve 8, a second limit plate 11 is connected to the side wall of the locking rod 9 located in the sleeve 8, and a spring 12 is sleeved on the side wall of the locking rod 9 located in the sleeve 8, the spring 12 is located between the first limit plate 10 and the second limit plate 11, a notch 14 is opened in the side wall of the end of the sleeve 8 away from the slider 6, a handle 13 is vertically connected to the upper end of the locking rod 9, and the other end of the handle 13 is located outside the sleeve 8 through the notch 14.

[0053] In this embodiment, the first slide rail 5 is connected to the side wall of the first door leaf 20 in the opening direction. When the first door leaf 20 and the second door leaf 21 need to be driven by the cylinder, the handle 13 is rotated into the notch 14. At this time, the spring is in a normal state, and the lower end of the locking rod 9 enters the socket 7 through the through hole, so that the slider 6 cannot move on the first slide rail 5. At this time, the piston rod 4 of the cylinder contracts to pull the first door leaf 20 to rotate. While the first door leaf 20 rotates, it drives the second door leaf 21 to rotate in the other direction.

[0054] When the cylinder fails, the lock rod 9 can be pulled outward through the handle 13 to compress the spring 12, and then the lock rod 9 can be rotated to place the handle 13 outside the notch 14. The lower end of the lock rod 9 is just located in the sleeve 8. At this time, the slider 6 can move in the first slide rail 5. When the staff pulls the first door leaf 20, it will not be supported by the piston rod, so that the first door leaf 20 and the second door leaf 21 can be manually closed and opened.

[0055] Furthermore, an adjusting air outlet 15 is opened on the side wall of the first door leaf 20 or the second door leaf 21. In this embodiment, the adjusting air outlet 15 opened on the second door leaf 21 is taken as an example for explanation. The two second slide rails 16 are respectively located above and below the adjusting air outlet 15. An adjusting air window 17 is slidably connected between the two second slide rails 16. The adjusting air window 17 corresponds to the position of the adjusting air outlet 15. When pressure relief is required, the adjusting air window 17 can be slid to the side. When not needed, the adjusting air window 17 can be slid to block the adjusting air outlet 15.

[0056] Furthermore, a pedestrian passage is opened on the side wall of the first door leaf 20 or the second door leaf 21. In this embodiment, the pedestrian passage is opened on the second door leaf 21 as an example. A sliding door track 33 is installed on the side wall of the second door leaf 21. A sliding door 34 is slidably connected to the sliding door track 33. The sliding door 34 corresponds to the position of the pedestrian passage. When only pedestrians enter and exit, the sliding door 34 can be slid to open the pedestrian passage, and pedestrians can enter and exit through the pedestrian passage, thereby reducing unnecessary losses.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
