In this embodiment, the support 30 is a rolling member, preferably a pulley. In other embodiments, the support portion 30 includes a slide rail and a slider that are slidably coupled, and the shutter plate 13 is slidably coupled to the slide rail via the slider.

Preferably, in the second state, before the shutter plate 13 is in interference fit with the seal 12, the shutter plate 13 is in rolling or sliding connection with the support 30; in the third state, when the shutter plate 13 is in clearance fit with the seal 12, the shutter plate 13 is in rolling or sliding connection with the support portion 30.

The support portion 30 is provided to support the shutter plate 13 when the shutter plate 13 moves in the first direction or the third direction, so that the movement stability of the shutter plate 13 is improved.

Referring to fig. 2 and 3, along a fifth direction (shown by an X direction in fig. 2 and 3), the gate housing 10 has a third mounting portion 50 and a fourth mounting portion 51 which are oppositely disposed, referring to fig. 2 to 7, the fifth direction, the first direction and the second direction are perpendicular to each other, the third mounting portion 50 and/or the fourth mounting portion 51 is provided with a plurality of supporting portions 30, and the plurality of supporting portions 30 are disposed along the first direction. In this embodiment, the supporting portion 30 is mounted in a plurality of positions on the third and fourth mounting

portions

50 and 51. In other embodiments, a plurality of the supporting portions 30 are mounted to the third mounting portion 50 or the fourth mounting portion 51.

Referring to fig. 2, in the present embodiment, two third stoppers 23 are disposed on the first mounting portion 17 at intervals along the fifth direction, and correspondingly, two first stoppers 21 engaged with the third stoppers 23 are disposed on the shutter plate 13; two fourth stoppers 24 are arranged on the second mounting portion 16 at intervals along the fifth direction, and correspondingly, two second stoppers 22 matched with the fourth stoppers 24 are arranged on the shutter plate 13. However, the number of the third stoppers 23 and the fourth stoppers 24 is not limited, and the following conditions are satisfied: after the first stopper 21 and the third stopper 23 are contacted, the first stopper 21 is moved in the second direction or the fourth direction along the surface of the third stopper 23 by the driving part 14, and after the second stopper 22 and the fourth stopper 24 are contacted, the second stopper 22 is moved in the second direction or the fourth direction along the surface of the fourth stopper 24 by the driving part 14.

In the second state, while the shutter plate 13 completely closes the first opening 11a, the shutter plate 13 is tightly attached to the sealing element 12, so that interference fit is achieved, and the sealing element 12 is pressed by the shutter plate 13 at the positions of the third stopper 23 and the fourth stopper 24, so that an airtight effect is achieved. In the present embodiment in particular, the seal 12 presents four airtight pressing points, i.e. is pressed by the shutter plate 13 at the position of the two third stops 23 and the two fourth stops 24. Preferably, referring to fig. 15 in combination with fig. 2, two third stoppers 23 are provided at corners F, H of the sealing member 12 extending in the fifth direction, and two fourth stoppers 24 are provided at corners E, G of the sealing member 12 extending in the fifth direction. That is, the seals 12 are tightly compressed by the shutter plate 13 at the four corners E, F, G, H, thereby achieving the airtight effect of the lock gate 1.

To sum up, the above embodiments provided by the present invention are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
