Suspension sliding door buffer and pulley device

The present invention relates to a pulley device for a suspended sliding door, and more particularly to a buffer and pulley device for a suspended sliding door, which is disposed on a top edge of a door panel mounted on a sliding door, thereby enabling the sliding door to be in a The door frame slides inside the track and cushions the door panel when opening, avoiding direct impact on the door frame. Wherein, the pulley device comprises a buffer and a quick release pulley assembly detachably coupled to the buffer. When the buffer fails, the user can quickly separate the buffer and the quick release pulley assembly to remove the door panel. And by this, the faulty buffer is quickly replaced, and the quick release pulley assembly is easy to disassemble and has high durability.

Suspended sliding door is a common construction device for interior design. It fits the original structure of the room and separates the indoor space. Because the hanging sliding door system is mounted on the track to slide, it is at the top of the door panel. A cushioning device is provided to reduce the speed at which the door panel slides, and the situation that the speed of the door panel or the door frame is too fast when the door panel is pulled is generated, causing noise or pinching the person.

For the configuration of the prior art suspension sliding door, as shown in FIG. 12, the mounting rail 80 is fixed in the door frame at the top of the room, the mounting rail 80 and the door frame are of the same length, and the opposite ends are in contact with the indoor two. Between the opposite wall surfaces, two opposite sliding rail portions 81 are formed at the bottom slot of the mounting rail 80. The buffering device 95 is disposed inside the mounting rail 80 with a door panel 90. The first pulley 96 is disposed at opposite ends of the buffering device 95. The second pulley 97, the first pulley 96, the second pulley 97, and the auxiliary pulley 98 abut against the rail portion 81, and can roll on the rail portion 81 along the longitudinal direction of the mounting rail 80. When actually assembled, The top of the door panel 90 is connected to the bottom of the first pulley 96 and the second pulley 97 and the auxiliary pulley 98.

Due to the use of the hanging sliding door, the door panel 90 often slides, so that the buffering device 95 must be repeatedly operated, so that the buffering device 95 needs to be worn and has the need for maintenance and replacement. However, the prior art is in the process of maintenance. After the connection between the door panel 90 and the first pulley 96, the second pulley 97, and the auxiliary pulley 98 is released, the entire mounting rail 80 must be removed from the door frame to remove the buffer device 95 from the end of the mounting rail 80. Further, the maintenance and replacement work of the shock absorbing device 95 is performed. Therefore, in terms of maintenance efficiency, the additional construction steps of removing the mounting rail 80 not only make the overall process complicated, but also increase the time required for maintenance.
