Suspended sliding door pulley device

The present invention relates to a pulley device for a suspended sliding door, and more particularly to a suspension sliding door pulley device which is arranged on a top edge of a door panel mounted on a sliding door, thereby enabling the sliding door to be in the rail of a door frame. Sliding and cushioning the door panel when opening, avoiding direct impact on the door frame. Wherein, the pulley device comprises a buffer and a shock-absorbing roller assembly combined with the buffer, which can prevent the roller assembly and the door panel from jumping up and down or left and right, and thereby improving the life and durability of the buffer and pulley device. And avoid the noise of jumping or shaking.

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.

Since the mounting rail 80 has a considerable gap between the first pulley 96, the second pulley 97 and the auxiliary pulley 98, the upper and lower jumps and lateral sway are easily generated when the door panel 90 slides 80 relative to the mounting rail, causing the first pulley 96. The second pulley 97 and the auxiliary pulley 98 are prone to excessive wear and even damage, resulting in damage, and it is easy to cause a beating noise during the sliding of the door panel, causing trouble to the user.

The present inventors have created a suspension type sliding door pulley device in view of the shortcomings of the existing pulley block of the hanging sliding door, which is easy to be swayed and swayed relative to the installation track.

The main purpose of the present invention is to provide a suspension sliding door pulley device which is arranged on the top edge of a door panel mounted on a sliding door, thereby enabling the sliding door to slide in the track of a door frame and to the door panel when opening the door. The buffer function is achieved to avoid direct impact on the door frame. Wherein, the pulley device comprises a buffer and a shock-absorbing roller assembly combined with the buffer, which can prevent the roller assembly and the door panel from jumping up and down or left and right, and thereby improving the life and durability of the buffer and pulley device.
