And, the slope of the slope of the first transmission member 271 is adapted to the slope of the slope of the second transmission member 272. Specifically, the width of the slope of the first transmission member 271 and the second transmission member 272 along the width direction of the door leaf 1 is the maximum distance of the second seal member 26 to move outward.

The arrangement of the transmission mechanism 27 facilitates the outward movement of the second sealing material 26 to seal the open side of the door leaf 1. Suitably, the grounding door 100 can also be provided with a mechanism for facilitating the return of the second sealing material 26 to the original position. For example, the ground door 100 can also include at least one set of support mechanisms 28 for moving the second sealant 26 back into place when the door leaf 1 is opened, increasing the useful life of the second sealant 26. For example, each of the second seals 26 may be provided with two sets of support mechanisms 28 disposed at the upper middle portion and the lower middle portion of the second sealant 26, respectively, so that the second sealant 26 is evenly stressed.

Specifically, the receiving mechanism 28 includes a first receiving member 281 and a second supporting member 282, wherein the first receiving member 281 is fixedly coupled to the second connecting rod 25, and the second receiving member 282 and the second sealing member 26 is fixedly connected, and the first support member 281 is connected to the second support member 282.

When the second pressing block 241 is disengaged from the pressure of the door frame when the door leaf 1 is opened, the second pressing piece 241 drives the first receiving member 281 to move upward through the second connecting rod 25 under the restoring force of the second spring 242. In the process, under the action of the inclined surface of the second receiving member 282, the first receiving member 281 forces the second receiving member 282 to drive the second sealing material 26 upward and simultaneously along the width direction of the door leaf 1. The inner seal is moved so that the second sealing material 26 can be returned to the original position after the door leaf 1 is opened.

In order to realize the smooth connection between the first support member 281 and the second support member 282 through the ramp and the second sealant 26 can be moved inward along the width direction of the door leaf 1, the top end of the first support member 281 is required. The width of the second receiving member 282 is greater than the width of the bottom end thereof; and the slope of the inclined surface of the first receiving member 281 and the slope of the inclined surface of the second receiving member 282 Adapted. Specifically, the width of the inclined surface of the first receiving member 281 and the second receiving member 282 along the width direction of the door leaf 1 should be greater than or equal to the width direction of the first transmission member 271 and the second transmission member 272 along the width of the door leaf 1. The width of the bevel is to ensure that the second sealing material 26 can return to its original position, thereby effectively ensuring its service life. Illustratively, in the embodiment shown in Figure 5, the structure of the support mechanism 28 is the same as that of the transmission mechanism 27, but the mounting direction is reversed.

In addition, according to the floor door 100 of the present invention, in order to further ensure that the sealing material can be restored to the original position when the door leaf 1 is opened, the floor door 100 further includes at least one first tension spring 291 and second tension spring 292. The first tension spring 291 is horizontally disposed, and the first end of the first tension spring 291 is fixedly coupled to the second link 25, and the second end of the first tension spring 291 is fixedly coupled to the second sealing member 26. In the closed state of the door leaf 1, as the second sealing material 26 moves outward under the action of the transmission device 27, the first tension spring 291 is in a stretched state; when the door leaf 1 is opened, the second sealing material 26 is in the first tension spring. Under the resilience of 291, it is easier and more convenient to restore the original position.

The second tension spring 292 is located at the junction of the first link 22 and the first sealing material 23 and is horizontally disposed. The first end of the second tension spring 292 is fixedly coupled to the first end 231 of the first sealing material 23, and the second end of the second tension spring 292 is fixedly coupled to the second end 222 of the first link 22.

Specifically, the bullet door 100 further includes a pin shaft 31 and a fixing member 32, wherein the second end 222 of the first link 22 is fixedly coupled to the end of the pin shaft 31, and the pin shaft 31 is perpendicular to the first link 22, the first end 231 of the first sealing material 23 is slidably connected to the pin shaft 31; the second end 232 of the first sealing material 23 and the bottom end 261 of the second sealing material 26 are fixedly connected by the fixing member 32. In this embodiment, the fixing member 2 is a fastening screw.

When the door leaf 1 is closed, under the action of the second control mechanism 24, the second link 25 slides down, so that the second sealing material 26 is moved outwardly and in the width direction of the door leaf 1 by the transmission mechanism 27, in the fixing member. Under the connection of 32, the second sealing material 26 drives the first sealing material 23 to slide away from the first connecting rod 22 along the axial direction of the pin shaft 31, and moves the second end 232 of the first sealing material 23 downward; When the first opening spring 291 and the receiving mechanism 28 act, the second sealing material 26 moves upward and close to the second connecting rod 25, thereby driving the first sealing material 23 along the axial direction of the pin shaft 31. Simultaneously, the second end 232 of the first sealing material 23 is moved upward; correspondingly, when the door leaf 1 is opened, under the action of the second tension spring 292, the first sealing material 23 will follow the pin. The axial direction of the shaft 31 moves closer to the first connecting rod 22, so that the second sealing material 26 can be brought closer to the second connecting rod 25, further ensuring that the second sealing member 26 is not exposed when the door leaf 1 is opened, ensuring the first The service life of the second seal 26.
