Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-4 The connecting structure of an elevator car and a shaft shown in the figure comprises an elevator shaft 7, a main guide rail 9 and a secondary guide rail 12 are installed at the inner wall position of the elevator shaft 7, a sky beam 6 is arranged at the upper end position of the elevator shaft 7, a control cabinet 4 for controlling the operation of the entire elevator is installed at the upper end of the sky beam 6 at the right position, a traction machine 5 is installed at the upper end of the sky beam 6 at the middle position, the traction machine 5 is started to move the traction rope 3 installed at the outer position, and the traction rope 3 moves the elevator car body 1 at the lower end position through the traction machine 5, a fixed sleeve 2 is arranged at the upper end position of the elevator car body 1, the fixed sleeve 2 sleeves the traction rope 3 at the inner position, the upper end of the fixed sleeve 2 is close to the outer wall of the traction rope 3 at the guide wheel 17 at the front and rear sides, and the upper and lower ends of the elevator car body 1 are respectively installed with a car frame upper beam 8 and a car frame lower beam 16. Safety clamps 10 are provided at the left and right end positions of the lower beam 16 of the car frame, and the car guide shoes 11 at the positions on both sides of the outer end surfaces of the upper beam 8 and the lower beam 16 of the car frame can move along the main guide rail 9. The outer end surfaces of the upper beam 8 and the lower beam 16 of the car frame are both installed with mounting bases 15, and a support frame 14 is fixed at the upper end position of the mounting base 15, and a connecting rod 18 is sleeved at the inner side position of the support frame 14, and the connecting rod 18 is sleeved at the inner position of the support frame 14 through the rotating shaft 21 at the left and right end positions, and a fixed block B23 is fixed at the inner position of the support frame 14, a torsion spring 22 is wound at the outer wall position of the rotating shaft 21, and a fixed block A20 is fixed at the upper end of the rotating shaft 21 at the outer position, and the wear-resistant brush 19 at the front end position of the connecting rod 18 is fitted with the main guide rail 9, and a rear buffer 13 is installed at the bottom position of the elevator car body 1.

[0024] When the passenger presses the floor button, the control cabinet 4 receives the signal and instructs the traction machine 5 to start. The traction machine 5 pulls the elevator car body 1 through the traction rope 3 to run on the main rail 9. The car rises or falls in the elevator shaft 7, guided by the main rail 9. Safety devices such as the car guide shoe 11 and the safety clamp 10 ensure the safety of the car during operation to prevent accidents.

[0025] like Figure 1 and Figure 2As shown, after the traction machine 5 starts working, the traction rope 3 moves, and the traction rope 3 pulls the elevator car body 1 to rise and fall. The traction rope 3 passes through the fixed sleeve 2 and is installed with the elevator car body 1. The movement of the traction rope 3 causes the guide wheel 17 to rotate. The control cabinet 4 and the traction machine 5 are both installed at the upper end of the sky beam 6. The control cabinet 4 can control the speed of the traction machine 5. During the lifting process of the elevator car body 1, the car guide shoe 11 moves along the main guide rail 9, and the main guide rail 9 is distributed on both sides of the inner wall of the elevator shaft 7.

[0026] The fixed sleeve 2 wraps the pulling rope 3 at the inner position, and the guide wheel 17 located at the upper end of the fixed sleeve 2 fits tightly with the pulling rope 3.

The rotation of the rotating shaft 21 compresses the torsion spring 22 through the fixed block A20.

[0028] The wear-resistant brush 19 is tightly attached to the outer wall of the main guide rail 9. When the elevator car body 1 is raised or lowered, the angle between the connecting rod 18 and the support frame 14 changes, so that the rotating shaft 21 compresses the torsion spring 22 through the fixed block A20. At the same time, the torsion spring 22 releases the compression force, so that the wear-resistant brush 19 is tightly attached to the outer wall of the main guide rail 9. During the operation of the elevator car, the wear-resistant brush 19 cleans impurities.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
