Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0025] See also Figure 1 and Figure 2 , this patent provides a technical solution: a bottom-mounted circular-arc elevator hall door device, comprising an elevator door sill body 10, wherein the elevator door sill body 10 comprises an elevator hall door body 11, a semi-arc upper sill 9 and an external cover plate 8, wherein the semi-arc upper sill 9 is arranged at the top of the elevator hall door body 11;

[0026] The external cover plate 8 is arranged on the outside of the elevator hall door body 11, and the guide rail 3 is installed on the inner upper end of the elevator hall door body 11;

[0027] The guide rail 3 is equipped with two sets of door slide assemblies 2 arranged opposite to each other, and the door slide assemblies 2 can move relative to each other on the guide rail 3, so as to realize the opening and closing of the elevator door;

[0028] The door slide assembly 2 includes two sets of guide wheel mechanisms 7 which are arranged opposite to each other and are mounted on the guide rail 3. The outer wall of the guide wheel mechanism 7 is equipped with a driving door plate 15.

[0029] The guide wheel mechanism 7 includes a guide wheel shaft 73, and the outer wall of the guide wheel shaft 73 is provided with a guide wheel groove 74, and the guide wheel groove 74 cooperates with the guide rail 3. The guide wheel shaft 73 can cooperate with the guide wheel 3 through the setting of the guide wheel groove 74, thereby realizing the movement of the guide wheel mechanism 7 on the guide rail 3.

[0030] A shaft cylinder 72 is installed on both sides of the guide wheel shaft 73, and a bearing plate 71 is installed on the outer wall of the shaft cylinder 72. The driving door plate 15 is connected to the bearing plate 71. There are two shaft cylinders 72, which are respectively installed on both sides of the guide wheel shaft 73. A bearing plate 71 is installed on the outer wall of each shaft cylinder 72 for connecting the driving door plate 15.

[0031] The inner wall of the shaft cylinder 72 is evenly provided with a rotating cavity 12 along its axis, and a ball 13 is installed inside the rotating cavity 12. The ball 13 is arranged in close contact with the guide wheel shaft 73, and the guide wheel shaft 73 can rotate in the shaft cylinder 72. When rotating, the ball 13 in close contact with it rotates successively, thereby improving the rotation efficiency of the guide wheel shaft 73.

[0032] An oil filling hole 14 is formed on the outer wall of the shaft cylinder 72 , and the oil filling hole 14 is communicated with the rotating cavity 12 . A hole plug is inserted into the oil filling hole 14 , and lubricating oil can be added into the rotating cavity 12 through the oil filling hole 14 .
