Referring to fig. 1 to 3, there is shown a structure of a connection structure of a pulley of an elevator in the related art. As shown, the pulley 31' of the elevator 3' is riveted to the guide rail 33' of the elevator 3' (as at B in fig. 1 and 2) with a connecting pin 32' to provide a defined winding direction for the wire rope.

Referring to fig. 4 and 5, a preferred structure of a pulley connection structure of an elevator according to an embodiment of the present invention is shown. For avoiding rocking of glass when closing the door and even colliding with the abnormal sound, provided a pulley connection structure of riser in this embodiment, pulley 1 sets up on the guide rail 3 of riser through hollow pin 2 for lead the rope of riser.

Specifically, the pulley 1 is fixed to an end of the guide rail 3 so as to guide a rope of the lifter. To ensure the stability of the pulley 1, it is preferable that the hollow pin 2 is riveted to the end of the guide rail 3 to guide the rope of the elevator as a fixed pulley, and of course, the pulley 1 may be a movable pulley slidably coupled along the guide rail 3. That is, both the fixed pulley and the movable pulley in the lifter can be connected to the guide rail 3 by the connection structure.

With continued reference to fig. 4 and 5, the hollow pin 2 is provided with a buffer hole 21 provided with a buffer plug 4 therein, and the buffer plug 21 is used for buffering glass when the vehicle door is opened and closed. Specifically, the hollow pin 2 is a pin shaft of a hollow cylindrical structure, that is, a buffer hole 21 is provided on the pin shaft of the cylindrical structure. For the buffering of realization to glass, preferably, be equipped with buffering stopper 4 in the buffering hole 21 to cushion glass when the switch door through buffering stopper 4, can avoid rocking of glass through the flexible contact between buffering stopper 4 and the glass, and shake the glass that causes and the rigidity contact between the especially hard spare of other spare parts because of glass, and then avoid glass with collide with the abnormal sound, reduce the noise and improve the quality of closing the door of glass lower dead center position, thereby improve user's use and experience. In order to avoid the stress concentration of the hollow pin 2, preferably, the buffer hole 21 is disposed along the axis of the hollow pin 2, that is, the buffer hole 21 is disposed at the axis of the hollow pin 2, so that the buffer plug 4 is disposed along the axis of the hollow pin 2, thereby avoiding the deformation of the hollow pin 2 caused by the stress concentration of the hollow pin 2 during the buffer action, such as inclination.

In the above embodiment, the buffer hole 21 is a circular through hole so that the buffer plug 4 is fitted in the buffer hole 21. Of course, the buffer hole 21 may also be a square through hole or a through hole with other shapes, which is not limited in this embodiment. In order to facilitate the installation and the disassembly of the buffer plug 4, the buffer plug 4 is preferably detachably connected with the hollow pin 2 so as to be directly disassembled on a vehicle type without the buffer plug 4, so that the buffer plug is simple in structure and good in universality.

In the above embodiment, the cushion plug 4 includes: the embedding part 41, the plug 42 and the bump 43; wherein the content of the first and second substances,

the embedding part 41 is arranged between the plug 42 and the bump 43, and the diameter of the bump 43 and the diameter of the end (the right end as shown in fig. 5) of the plug 42 close to the embedding part 41 are both larger than the diameter of the embedding part 41, so that the embedding part 41 is inserted into the buffer hole 21 and is pressed against the left side and the right side of the hollow pin 2 through the plug 42 and the bump 43, and the buffer plug 4 and the hollow pin 2 are fixedly installed. The embedding portion 41 is a cylindrical structure adapted to the buffer hole 21, and the protrusion 43 is a truncated cone-shaped protrusion structure. In order to facilitate the assembly and disassembly of the buffer plug 4 even if the buffer plug 4 is inserted into the buffer hole 21, preferably, the plug head 42 has a frustum structure, and the diameter of the end (left end as shown in fig. 5) of the plug head 42 far away from the embedding part 41 is smaller than the diameter of the end (right end as shown in fig. 5) of the plug head 42 close to the embedding part 21, that is, the diameter of the plug head 42 from the left end to the right end is gradually increased, so that the buffer plug 4 is inserted into the buffer hole 21 from the right to the left, and the installation between the two is realized. When the buffer plug 4 buffers the glass, the buffer plug 4 buffers the glass through elastic deformation of the buffer plug 4, that is, the buffer plug 4 itself has micro-deformation. To reduce friction between the embedding portion 41 and the buffer hole 21, it is preferable that the diameter of the embedding portion 41 is smaller than or equal to the inner diameter of the buffer hole 21 to avoid abrasion of the embedding portion 41.
