Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present invention and should not be construed as limiting the present invention.

As shown in fig. 1 to 5, a plug door apparatus 100 according to an embodiment of the present invention includes: door panel 11, door frame 12 and drive member 3.

Specifically, the door panel 11 extends in the up-down direction, the door frame 12 is mounted on the door panel 11, the door frame 12 is fixedly connected to the door panel 11, the driving member 3 includes a fixing portion and a driving portion, the driving portion is fixedly connected to the corresponding door frame 12, and the driving portion and the fixing portion are relatively movable to drive the door panel 11 to move in the left-right direction.

Wherein the gantry 12 connecting the drive part and the door panel 11 is adjustable in position relative to at least one of the door panel 11 and the drive part.

For example, the relative position of the door frame 12 connecting the driving portion and the door panel 11 to the door panel 11 is adjustable; or the relative position of the driving part of the door frame 12 connecting the driving part and the door plate 11 can be adjusted; or the relative positions of the door frame 12 connecting the driving part and the door panel 11 and the driving part can be adjusted.

Therefore, the relative position of the door panel 11 and the driving portion of the driving member 3 can be adjusted by the gantry 12, thereby adjusting the position of the door panel 11.

The two components are fixedly connected and adjustable in position, namely, the two components are fixedly connected in the use process, and can move relatively only when adjustment is needed. For example, when the relative position of the two components needs to be adjusted, the position of the two components can be adjusted, and when the two components are used after the adjustment is completed, the two components can maintain a fixed connection state.

For example, if the door frame 12 and the door panel 11 are fixedly connected and the relative position is adjustable, it means that the door frame 12 and the door panel 11 are fixedly connected during the use process, and the door frame 12 and the door panel 11 can move relatively only when the adjustment is needed. Specifically, when the relative position between the door frame 12 and the door panel 11 needs to be adjusted, the positions of the door frame 12 and the door panel 11 can be adjusted, and when the door frame 12 and the door panel 11 are used after the adjustment is completed, the fixed connection state is maintained.

Additionally, the gantry 12 of the present invention is used to connect other components of the plug door apparatus 100, for example, the gantry 12 may be configured to connect to a load bearing assembly (e.g., a load bearing trolley, a plug trolley, etc.) of the plug door apparatus 100, the drive member 3, etc.

A plurality of gantries 12 may be provided to connect the load bearing assembly and the drive member 3, respectively.
