[0005] Furthermore, the opening and closing cover is made of fiberglass.

[0006] Furthermore, the embedded screw sleeve plate is made of metal.

[0007] Furthermore, the transition piece is fixedly connected to the opening and closing mechanism by bolts.

[0008] Furthermore, the bolt holes on the two planes of the transition piece sleeve are both oblong holes, which facilitates position adjustment during installation.

[0009] Furthermore, the embedded screw sleeve plate is provided with four screw sleeves, and four bolt holes are respectively provided on the two planes of the transition piece, and the opening and closing mechanism is fixedly connected to the transition piece by four bolts.

[0010] The rail vehicle opening and closing cover installation structure of the utility model is provided with four on the opening and closing cover, and the installation bolts are fastened to the embedded screw sleeves of the opening and closing cover through the transition piece, so as to fix the opening and closing cover on the opening and closing mechanism. The utility model makes the installation interface of the opening and closing cover and the opening and closing mechanism completely built into the opening and closing cover, which can effectively prevent the previous installation point from being bumped and scratched, increase the reliability and safety of the opening and closing cover installation, reduce the failure rate of the opening and closing mechanism, prevent the opening and closing cover from being scrapped, and make installation and maintenance faster. In addition, the internal embedded screw sleeve plate has a high demoulding rate, which increases the product quality. BRIEF DESCRIPTION OF THE DRAWINGS
