DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] Example 1

[0032] An embodiment of the present application discloses a civil defense door for a mountain rail transit section.

[0033] Reference Figure 1 The civil defense door in the mountain rail transit section includes a door frame 1, a door leaf 2 and a connecting mechanism 3. The door frame 1 is installed on the track section structure. The door leaf 2 is hingedly installed on the side walls on the left and right sides of the door frame 1. In this embodiment, the left and right lines of the track are both located in the door frame 1.

[0034] By rotating the two door leaves 2 closer to each other, the two door leaves 2 can close the opening of the door frame 1 and isolate the track section as a protection unit. In addition, by using two door leaves 2, the space required for opening the door leaves 2 can be reduced, the design length of the civil defense section can be compressed, the door leaves 2 can be opened and closed conveniently, and the construction cost can be saved.

[0035] Reference Figure 1 , Figure 2 A threshold 5 is installed at the bottom of the door frame 1, and four rail grooves 51 are opened on the threshold 5. The four rail grooves 51 are respectively used for two tracks of the left and right lines to pass through.

[0036] By installing the threshold 5 at the bottom of the door frame 1, the threshold 5 can block the bottom of the track section, block the water in the track, and prevent water from flowing at the bottom of the track section; and by providing a track groove 51 for the track to pass through, the track can be built into the threshold 5 to avoid the track protruding, so that the door leaf 2 can abut against the upper part of the threshold 5 when closed, thereby better closing the track section and enhancing the overall sealing of the civil defense door.

[0037] Reference Figure 1 , Figure 2 A plurality of water holes 52 are provided on the threshold 5, and a closing assembly 6 is installed on the threshold 5. The closing assembly 6 is used to close the water holes 52. The closing assembly 6 includes a slide plate 61 and a tightening bolt 62. In the present embodiment, a support frame is installed on the side wall of the threshold 5. The slide plate 61 is slidably installed on the support frame along the direction toward the side wall of the threshold 5. The tightening bolt 62 is rotatably installed on the support frame. The tightening bolt 62 is threadedly connected to the slide plate 61. In the present embodiment, a rubber sealing ring is circumferentially installed on one side of the slide plate 61 facing the threshold 5. The rubber sealing ring can be tightened to the threshold 5 in the circumferential direction of the water holes 52, thereby enhancing the sealing of the slide plate 61 against the door frame 1 to close the water holes 52.

[0038] The staff rotates the tightening bolt 62, and the tightening bolt 62 drives the slide plate 61 to move towards the door sill 5, and the slide plate 61 can be pressed against the door sill 5 to close the water hole 52, so that the door sill 5 maintains its water blocking effect; when drainage is required, the staff rotates the tightening bolt 62 in the opposite direction, so that the slide plate 61 moves away from the door sill 5, and the water hole 52 is opened, and water can be discharged through the water hole 52, thereby meeting the drainage requirements of the track section, and the staff can conveniently control the opening and closing of the water hole 52.

[0039] Reference Figure 1 , Figure 3 The connecting mechanism 3 is installed on the door leaf 2, and the connecting mechanism 3 is used to support the door leaf 2. The connecting mechanism 3 includes an embedded part 31 and a telescopic pull rod 32. The embedded part 31 is installed on the track interval structure. The embedded part 31 includes an anchor rod 311, and the anchor rod 311 extends to the wall of the track interval structure and is anchored therein; the telescopic pull rod 32 is hingedly installed on the anchor rod 311, and the telescopic pull rod 32 is hingedly connected to the door leaf 2. The length of the telescopic pull rod 32 can be extended and retracted as the door leaf 2 is opened and closed. The telescopic direction of the telescopic pull rod 32 is consistent with the rotation direction of the opening and closing of the door leaf 2. The telescopic pull rod 32 includes a guide sleeve 321 and a guide rod 322. The guide sleeve 321 is hingedly installed on the anchor rod 311. The guide sleeve 321 is hollow inside and one end away from the anchor rod 311 is open. The guide rod 322 is slidably inserted in the guide sleeve 321, and the end of the guide rod 322 away from the guide sleeve 321 is hingedly installed on the door leaf 2.

[0040] When the door leaf 2 is opened and closed, the door leaf 2 drives the guide rod 322 to slide on the inner wall of the guide sleeve 321. The inner wall of the guide sleeve 321 guides and supports the movement of the guide rod 322, so that the guide rod 322 can only move along the opening and closing direction of the door leaf 2, and then support the door leaf 2. At the same time, the door frame 1 supports the door leaf 2, so that the door leaf 2 can only move along the opening and closing direction, preventing the door leaf 2 from shifting or deforming under the action of gravity, and effectively improving the stability of the civil defense door in the mountain rail transit section under normal operation; and by adopting the anchor rod 311 to firmly anchor the track section structure, the anchor rod 311 further firmly supports the guide sleeve 321, effectively improving the stability of the guide sleeve 321, and then improving the stability of the guide sleeve 321 supporting and guiding the guide rod 322.

[0041] Reference Figure 1 , Figure 3The opening diameter of the opening end of the guide sleeve 321 is smaller than the internal opening diameter of the guide sleeve 321. A limiting ring 4 is installed at one end of the guide rod 322 that slides inside the guide sleeve 321. The diameter of the limiting ring 4 is the same as the internal opening diameter of the guide sleeve 321. When the door leaf 2 is closed to seal the door frame 1, the limiting ring 4 just abuts against the inner wall of the opening end of the guide sleeve 321.

[0042] When the door leaf 2 is closed and drives the guide rod 322 to move, the guide rod 322 moves in the guide sleeve 321 in the direction away from the bottom wall of the guide sleeve 321. When the door leaf 2 is closed to close the door frame 1, the limit ring 4 abuts against the inner wall of the open end of the guide sleeve 321 to limit the movement of the guide rod 322 and prevent the guide rod 322 from further sliding out of the guide sleeve 321, thereby improving the stability of the guide rod 322 in the guide sleeve 321, and the guide rod 322 can limit the rotation angle of the door leaf 2 when it is closed, so that the maximum rotation angle of the door leaf 2 can only be rotated to the closed state, thereby preventing the door leaf 2 from rotating excessively.

[0043] The implementation principle of Example 1 of the present application is: when the door leaf 2 is opened and closed, the door leaf 2 drives the guide rod 322 to slide in the guide sleeve 321. The inner wall of the guide sleeve 321 supports the guide rod 322 and guides the sliding of the guide rod 322, so that the door leaf 2 can only rotate along the opening and closing direction, preventing the door leaf 2 from shifting or deforming under the action of gravity, and effectively improving the stability of the civil defense door in the mountain rail transit section under normal operating conditions.

[0044] Example 2

[0045] Reference Figure 4 The difference between the embodiment of the present application and embodiment 1 is that the telescopic pull rod 32 includes a hydraulic cylinder 323, the hydraulic cylinder 323 is hingedly mounted on the anchor rod 311, the piston rod of the hydraulic cylinder 323 is hingedly mounted on the door leaf 2, and the telescopic direction of the piston rod of the hydraulic cylinder 323 is consistent with the rotation direction of the door leaf 2.

[0046] The implementation principle of Example 2 of the present application is: the staff can drive the door leaf 2 to rotate to close the door frame 1 by controlling the extension of the piston rod of the hydraulic cylinder 323, and can open the door leaf 2 by controlling the retraction of the piston rod of the hydraulic cylinder 323, thereby effectively improving the convenience of the staff in controlling the opening and closing of the door leaf 2.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
