It should be understood that the specific features in the embodiments of this application and the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. Without conflict, the technical features in the embodiments of this application and the embodiments can be combined with each other.

[0029] As Figures 1-9 shown, a movable glass opening and closing mechanism for a door includes a skeleton structure, a glass assembly, a glass control assembly and a glass limit assembly;

[0030] The skeleton structure includes a cab skeleton 1 and door skeletons 2 symmetrically installed on both sides of the cab skeleton 1. The door skeletons 2 are movably installed on the cab skeleton 1 to realize the opening and closing of the door;

[0031] The glass assembly is hinged to the skeleton structure. The glass assembly includes glass 4, a gasket 5 and a glass skeleton 6. The glass skeleton 6 can be formed by welding a bent pipe and a rib plate, and the material is not limited to metal only; the glass 4 is installed on the glass skeleton 6, and the gasket 5 is installed between the glass skeleton 6 and the glass 4. A glass control assembly and a glass limit assembly are installed on the glass assembly. The glass control assembly cooperates with the glass limit assembly to control the glass 4 to achieve 180° opening and locking.

[0032] In some embodiments, as Figure 1 shown, the glass assembly is installed on the door skeleton 2 through a hinge 3, so that the door glass can easily achieve an opening of 180° or even a larger angle.

[0033] In some embodiments, as Figure 1 、 Figure 5 and Figure 6As shown, the glass control assembly includes a pull rod door lock 7 and a catch bracket 9. The pull rod door lock 7 is installed on the glass skeleton 6. The pull rope on the pull rod door lock 7 passes through the inside of the glass skeleton 6 and is connected to the glass limit assembly 15. The catch bracket 9 is installed on the glass 4.

[0034] In some embodiments, as Figure 7 shown, a lock cover 8 is installed on the catch bracket 9. The lock cover 8 can hide part of the glass limit assembly structure. The pull rope of the pull rod door lock 7 passes through the inside of the glass skeleton 6 and is not visible, improving the overall aesthetics of the cab.

[0035] In some embodiments, as Figure 1 、 Figure 4 and Figure 6 shown, the glass limit assembly includes a positioning lock and a limit bracket 12. The positioning lock includes a positioning lock body 11 and a positioning lock post 13.
