During operation, the utility model can not only improve the stability of the connection between the door hanging wheel 8 and the pressure wheel 7 and the guide rail, making it difficult for them to separate from the guide rail, but also make the upper sill frame body 1 more firmly installed on the upper sill support frame in the elevator.

[0025] As a preferred embodiment, the reinforcement assembly includes a rectangular hole 11, a first bolt 16, a support plate 13, a first threaded rod 14, a first nut 15 and a pressure plate 12. The front end surface of the protruding plate 10 is provided with a rectangular hole 11. The front end of the protruding plate 10 is connected to two support plates 13 by a first bolt 16. The interiors of the two support plates 13 are both slidably connected with the first threaded rod 14. The upper ends of the two first threaded rods 14 are fixedly connected with a pressure plate 12. The pressure plate 12 passes through the rectangular hole 11 and is located at the upper end of the upper frame body 1. Each pressure plate 12 is located between the corresponding two mounting holes 20. The circumferential surface of the first threaded rod 14 is threadedly connected with the first nut 15. The first nut 15 is located at the lower end of the support plate 13. During operation, the support plate 13 is installed at the front end of the convex plate 10 by means of bolts, and then the mounting holes 20 are used in conjunction with the screws to fix the upper sill frame body 1 to the upper sill support frame, and then the first threaded rod 14 is used to penetrate the support plate 13 and press on the upper sill support frame, and then the first nut 15 is installed on the circumferential surface of the first threaded rod 14. Through the cooperation of the mounting holes 20 and the screws and the tight pressing of the pressure plate 12, double fixation can be achieved, so that the upper sill frame body 1 can be more firmly installed on the upper sill support frame in the elevator.

[0026] As another preferred embodiment, the connecting member includes a through hole 17, a second threaded rod 19 and a second nut 18. The front end of the upper frame body 1 is fixedly connected to the second threaded rod 19, and the circumferential surface of the second threaded rod 19 is threadedly connected to the second nut 18. The front end surface of the connecting frame 4 is provided with a through hole 17, the second threaded rod 19 passes through the connecting frame 4 through the through hole 17, and the second nut 18 is located at the front end of the connecting frame 4. During operation, after the second nut 18 is rotated along the second threaded rod 19 to move it away from the connecting frame 4, the connecting frame 4 can be moved upward along the second threaded rod 19 to drive the limiting frame 5 to move upward until the distance between the limiting frame 5 and the first guide rail 2 is greater than the size of the door hanging wheel 8, so that it is convenient to install the door hanging wheel 8 on the first guide rail 2, and then move the connecting frame 4 and the limiting frame 5 downward so that the limiting frame 5 blocks the upper end of the door hanging wheel 8.

[0027] Further preferably, two reinforcing plates 9 are fixedly connected inside the first guide rail 2. When working, the reinforcing plates 9 can improve the stability of the first guide rail 2 and prevent the first guide rail 2 from being deformed by the pressure of the door hanging wheel 8.

[0028] Further preferably, the upper sill frame 1, the first guide rail 2, the second guide rail 3 and the convex plate 10 are an integrated structure and are all made of galvanized sheet materials. During operation, the galvanized sheet materials not only have excellent anti-corrosion ability and strong toughness, but are also more durable. Therefore, the upper sill frame 1, the first guide rail 2, the second guide rail 3 and the convex plate 10 made of galvanized sheet materials are more durable and corrosion-resistant.

[0029] Working principle:

[0030] When in use, the upper sill frame body 1 is installed in the upper sill support frame in the elevator. The upper sill frame body 1 can not only be connected to the upper sill support frame by means of screws and mounting holes 20, but can also be reinforced by means of reinforcement components, so that the upper sill frame body 1 can be more firmly installed on the upper sill support frame in the elevator. During specific use, the limit frame 5 and the first guide rail 2 are respectively distributed at the upper and lower ends of the door hanging wheel 8, and the upper and lower ends of the door hanging wheel 8 are limited at the same time, so that the door hanging wheel 8 can move more stably on the first guide rail 2, and because the door hanging wheel 8 and the pressure wheel 7 are connected by the hanging plate assembly 6, the stability of the pressure wheel 7 on the second guide rail 3 can be improved, so that the door hanging wheel 8 and the pressure wheel 7 are not easy to detach from the guide rail.
