Description

Technical Field

[0001] This utility model relates to the field of partition door technology, and in particular to a protective and sealed partition door with a movable threshold in a subway section. Background Technology

[0002] Subway partition doors are the main protective facilities of subway civil defense projects and an extremely important component of the entire subway civil defense project. They serve to separate protective units and ensure that the protective functions of other protective units are not affected if the protective function of one protective unit is lost during wartime.

[0003] In existing technologies, buffer strips are mainly used to cushion the closing of partition doors, thereby reducing the collision between the partition door and the door frame. However, the buffer strips on existing partition doors are in fixed positions. With frequent opening and closing, they are subjected to long-term pressure, which can easily lead to surface wear and wear on the outer wall. Gradually, they can no longer effectively absorb the impact force when the door closes. When the partition door closes again, it will still generate a large impact force, which will put additional pressure on the door frame, door leaf and sealing strip, affecting the service life of the door. Therefore, it is necessary to propose a protective and sealed partition door with a movable threshold for subway sections to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Referring to Figures 1-5 A subway section movable threshold protection sealing partition door, including door frame 1 and door body 2, door body 2 rotates in door frame 1 by pivot, the inner wall of door body 2 is fixedly connected with baffle 5, the outer wall of baffle 5 and the outer wall of door frame 1 are on the same horizontal plane, the outer wall of baffle 5 is fixedly connected with two groups of air cylinders 7, one end of two groups of air cylinders 7 is set as open, and the inside is slidably connected with sliding rod 15, sliding rod 15 is set through baffle 5, the end of sliding rod 15 is fixedly connected with buffer strip 6, buffer strip 6 is in contact with the outer wall of door body 2, moving block 14 is slidably connected in air cylinder 7, sliding rod 15 is fixedly connected at the axis of moving block 14, compensation mechanism that compensates the position of buffer strip 6 is installed in air cylinder 7;

[0023] Specifically, by means of the buffer strip 6 arranged, when the door body 2 is closed, the impact force between the door body 2 and the door frame 1 in the closing process can be effectively absorbed and alleviated.

[0024] The compensation mechanism includes piston two 13 slidably connected in the air cylinder 7, the outer wall of piston two 13 is fixedly connected with spring 16, the other end of spring 16 is fixedly connected with moving block 14.

[0025] Specifically, by means of the elastic performance of spring 16 itself, when the outer wall of buffer strip 6 is abraded, under the action of spring 16, buffer strip 6 can always keep close contact with the outer wall of door body 2, so that even in the long-term use process, buffer strip 6 can still effectively absorb the impact force when the door body 2 is closed, and the excessive collision force between the door body 2 and the door frame 1 is avoided.

[0026] The outer wall of the door frame 1 is fixedly connected with a device cylinder 3, the outer wall of the device cylinder 3 is provided with an air pipe 4, the air pipe 4 penetrates through the door frame 1 and is communicated with the interiors of the two groups of air cylinders 7, a threaded rod 8 is rotatably connected in the device cylinder 3, the threaded rod 8 is coaxially and fixedly connected with the adjacent rotating shaft, the end of the threaded rod 8 is fixedly connected with a limiting block 12, and the radius size is greater than the radius of the threaded rod 8, a sliding block 9 is threadedly connected on the threaded section of the threaded rod 8, the end surface of the sliding block 9 is fixedly connected with two groups of connecting rods 11, the two groups of connecting rods 11 are symmetrically arranged, and the end portions of the two groups of connecting rods 11 are commonly connected with a piston one 10, and the outer wall of the piston one 10 is in contact with the inner wall of the device cylinder 3.

[0027] Specifically, when the door body 2 is closed, the threaded rod 8 drives the piston one 10 to slide upwards, drives the piston two 13 to drive the buffer strip 6 to slide to one side of the door body 2, and the piston one 10 is fed forward, so that the buffer strip 6 can provide greater and continuous contact pressure, effectively enhancing the ability of the buffer strip 6 to absorb impact force. When the door body 2 is closed, the buffer strip 6 can better contact the door body 2, reducing the reaction force of the impact, thereby protecting the door body 2, the door frame 1 and other components from damage.

[0028] In the utility model, when the door body 2 is in the open state, passengers or staff can normally pass, at this time, the buffer strip 6 is in the original state and is not subjected to external pressure.

[0029] When the door body 2 starts to close, the buffer strip 6 first contacts the door frame 1, and under the support of the sliding rod 15, a certain buffering effect is exerted on the door body 2, so that the door body 2 does not directly impact the door frame 1. With the further closing of the door body 2, the sliding rod 15 enters the interior of the air cylinder 7 under the driving of the moving block 14, and gradually compresses the spring 16. At this time, the spring 16 starts to store elastic energy, so that the buffer strip 6 can automatically adapt to different closing forces and always maintain close contact with the outer wall of the door body 2, thereby absorbing the impact force when the door body 2 is closed, reducing vibration and noise.

[0030] At the same time, the threaded rod 8 in the device cylinder 3 is driven to rotate during the closing of the door body 2, drives the sliding block 9 to slide along the axial direction of the threaded rod 8, the connecting rods 11 fixedly connected to the end surface of the sliding block 9 are synchronously pushed forward, finally the piston one 10 moves upwards, and further pushes the piston two 13, drives the buffer strip 6 to slide to the direction of the door body 2. Ensure that the buffer strip 6 can always maintain appropriate pre-tightening force under different closing states to adapt to the wear after long-term use, thereby prolonging the service life.

[0031] When the door body 2 is opened again, the threaded rod 8 is reversely rotated, drives the sliding block 9 and the connecting rods 11 to reset, the piston one 10 is withdrawn, and the buffer strip 6 gradually returns to the original position under the restoring force of the spring 16, ensuring that it can still provide effective buffering and sealing effect during the next closing.

[0032] In summary, the device realizes the buffer control and sealing compensation function in the closing process of the door body 2 through the cooperation of the air cylinder 7, the buffer strip 6, the spring 16 and the piston mechanism, so that the buffer strip 6 can still work effectively after long-term use, avoiding the problem that the traditional fixed buffer structure causes the buffer capacity to decrease due to wear, and improving the service life and safety of the door body 2.

[0033] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
