[0024] The present application discloses a vehicle door fastener, like Figure 1 and Figure 2The door fastener comprises a hanging plate unit 1, a pressing plate unit 2 and a fastening unit 3. The hanging plate unit 1 and the pressing plate unit 2 are separate components, the hanging plate unit 1 is matched with and connected to the vehicle body edge side plane 41, the pressing plate unit 2 is matched with the vehicle door edge side plane 51 on the same side of the vehicle body edge side plane 41, and the pressing plate unit 2 is connected to the outer side flange 6 of the vehicle door edge side plane 51. The fastening unit 3 is perpendicular to the vehicle body edge side plane 41, and the fastening unit 3 is connected to and fastens the hanging plate unit 1 and the pressing plate unit 2 in an adjustable manner.

[0025] Through the implementation of the above-mentioned door fastener embodiment, the hanging plate unit 1 is matched with and connected to the vehicle body edge side plane 41 to fix the hanging plate unit 1 to the vehicle body, the pressing plate unit 2 is matched with the vehicle door edge side plane 51 on the same side of the vehicle body edge side plane 41, the fastening unit 3 is connected to and fastens the hanging plate unit 1 and the pressing plate unit 2 in an adjustable manner, and the pressing plate unit 2 is connected to the outer side flange 6 of the vehicle door edge side plane 51. When the hanging plate unit 1 and the pressing plate unit 2 are fastened, the hanging plate unit 1 is attached to the vehicle door edge side plane 51 and fixed to the vehicle door edge side plane 51, so that the hanging plate unit 1 and the pressing plate unit 2 are located on the edge side of the vehicle body and clamp the vehicle door edge side plane 51 to match the structure of the vehicle door after the railway freight shed car is modified, the vehicle door is pressed tightly to the vehicle body, and the reinforcement effect is achieved to prevent the vehicle door from moving and displacing, and the vehicle door from being out of frame. At the same time, the fastening unit 3 is perpendicular to the vehicle body edge side plane 41, the fastening unit 3 is arranged on the edge side of the vehicle body, and the activity range of the fastening unit 3 does not exceed the outer side of the vehicle door in any case, so that the over-limit problem is avoided and the train safety is ensured.

[0026] Further, the hanging plate unit 1 comprises a first plate body 11 and a second plate body 12 arranged in parallel, and an arc-shaped plate body 13 connected to the same side ends of the first plate body 11 and the second plate body 12. The first plate body 11 and the second plate body 12 form a hanging groove 14 matched with a pre-set long hole on the vehicle body edge side plane 41.

[0027] Through the implementation of the above-mentioned door fastener embodiment, the first plate body 11, the second plate body 12 and the arc-shaped plate body 13 are connected and integrally formed to form a "U" type structure, so that the hanging plate unit 1 can be hung on the pre-set long hole on the vehicle body edge side plane 41 through the hanging groove 14 between the first plate body 11 and the second plate body 12. At this time, the groove opening of the hanging groove 14 faces downward, the first plate body 11 is located on the inner side of the vehicle body edge side plane 41 and attached to the inner surface of the vehicle body edge side plane 41, and the second plate body 12 is located on the outer side of the vehicle body edge side plane 41 and attached to the outer surface of the vehicle body edge side plane 41, so that the hanging plate unit 1 is positioned on the vehicle body and cannot move horizontally.

[0028] Further, the length of the first plate body 11 is greater than the length of the second plate body 12, so that the support area of the first plate body 11 is greater than the support area of the second plate body 12.
