Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 , the utility model provides a technical solution:

[0020] A push-pull gate is installed on a wall 1. A door opening 2 is provided on the wall 1. The gate comprises an upper support mechanism 3, a lower support mechanism and two sets of movable doors 4. The upper support mechanism 3 is horizontally arranged on the wall 1 and is located directly above the door opening 2. The two sets of movable doors 4 are movably connected to the upper support mechanism 3 respectively. The two sets of movable doors 4 can move left and right in the horizontal direction and can close the door opening 2. The lower support mechanism comprises two channel steels 5 horizontally installed on the ground. The two channel steels 5 are located on both sides of the door opening 2. The extension direction of any channel steel 5 is the same as the sliding direction of any movable door 4. The bottom end of any movable door 4 is slidably connected to the corresponding channel steel 5.

[0021] In this embodiment, the door opening 2 opened on the wall 1 is convenient for pedestrians and vehicles to pass through. The upper support mechanism 3 is used to install two movable doors 4, and the two movable doors 4 can move left and right to realize the opening and closing of the door opening 2. The lower support mechanism is used to guide the two movable doors 4 so that the movable doors 4 do not slide randomly.

[0022] In some implementations of the present embodiment, the upper support mechanism 3 is a columnar structure, the cross-section of the upper support mechanism 3 is rectangular, a through groove 6 is provided on the side of the upper support mechanism 3 close to the movable door 4, and the width of the through groove 6 is smaller than the width of the upper support mechanism 3; at least two groups of sliding mechanisms 7 are arranged in the upper support mechanism 3, and the execution ends of the two groups of sliding mechanisms 7 pass through the through groove 6 and are respectively connected to the two groups of movable doors 4.

[0023] In this embodiment, the upper support mechanism 3 is designed as this structure, which facilitates the movable door 4 to move left and right under the drive of the sliding mechanism 7 to realize the opening and closing of the door opening 2.

[0024] In some implementations of this embodiment, the sliding mechanism 7 is a hanging conveying chain, and a connecting rod 701 is provided on the hanging conveying chain. The free end of the connecting rod 701 extends out of the through slot 6 and is connected to the movable door 4.

[0025] In this embodiment, the sliding mechanism 7 adopts a suspension conveying chain, which can suspend the movable door 4 on the upper support mechanism 3 and facilitate the movable door 4 to move left and right on the upper support mechanism 3, so as to realize the opening and closing of the door opening 2. The sliding mechanism 7 can be composed of a connecting rod 701, a running wheel 702, two chain plates 703 and two guide wheels 704. The two guide wheels 704 are rotatably arranged on the two chain plates 703 respectively. The two chain plates 703 are detachably connected. The running wheel 702 is rotatably arranged at the connection of the two chain plates 703. One end of the connecting rod 701 is connected to the running wheel 702, and the other end extends out of the through groove 6 to connect with the movable door 4; the running wheel 702 and the two guide wheels 704 can abut against the inner wall of the upper support mechanism 3. In this structure, the two guide wheels 704 play a guiding role, the running wheel 702 plays a role of bearing weight and "walking", and the connecting rod 701 connects the suspension conveying chain and the movable door 4. In this embodiment, one movable door 4 is controlled by two sets of suspension conveying chains.

[0026] In some implementations of the present embodiment, the cross-section of the channel steel 5 is in a "concave" shape, and the opening of the channel steel 5 faces the movable door 4. Two pulleys 8 are symmetrically arranged at the bottom end of any movable door 4. Any pulley 8 is rotatably connected to the movable door 4, and any pulley 8 can abut against the inner bottom of the channel steel 5.

[0027] In this embodiment, two channel steels 5 installed on the ground respectively guide the movement of the two moving doors 4. The pulley 8 at the bottom of the moving door 4 can roll back and forth in the channel steel 5, thereby improving the continuity of the movement of the moving door 4.

[0028] In some implementations of this embodiment, the arbitrary movable door 4 is a frame structure.

[0029] In this embodiment, the movable door 4 is a frame structure, which is convenient for manufacturing. The movable door 4 can be composed of a door panel main rib 401, a door panel secondary rib 402 and a plurality of embedded door panels 403, wherein the plurality of embedded door panels 403 are installed in the door panel secondary rib 402, the door panel secondary rib 402 is installed in the door panel main rib 401, and the door panel main rib 401 is connected to the connecting rod 701. When the movable door 4 is hit and the embedded door panel 403 is partially damaged, only the damaged embedded door panel 403 needs to be replaced, and the entire movable door 4 does not need to be replaced, which indirectly reduces the use cost.
