Description

Sliding assembly

Technical Field

The utility model relates to a sliding door field especially relates to a sliding assembly.

Background

The sliding door prevents the sliding door from colliding with the two sides of the door frame through the matching of the damper and the pulley. One of them is to fix the damper relative to the rail, and the sliding block in the damper is used in cooperation with the pulley on the door. When the damper and the damper are engaged, the damper provides a tensile force through the spring and a damping force through the damping tube. After disengaging, the pulley is free to move relative to the damper.

In the prior art, patent CN201510552826.3 provides a sliding guide device convenient for installing a damper, and when the sliding guide wheel assembly moves, the toggle part is engaged with or disengaged from the hook, so as to play a damping role. However, when the sliding guide device is actually used, although the pulley has a certain self-balancing effect, the pulley is slightly small, and certain noise is generated; the main mounting block has a significant protrusion in the middle, but the opening at the lower end of the rail is small, and this protrusion will easily cause unnecessary friction with the lower edge of the rail and also generate noise.

SUMMERY OF THE UTILITY MODEL

To prior art's defect, the utility model aims to provide a take slip silence, the good slip subassembly of self-balancing pulley of self-balancing effect.

The utility model adopts the technical proposal that: a sliding assembly comprises a pulley and a damper arranged on a sliding door guide rail; the damper is provided with a shell and a sliding block; the pulley comprises a main body and wheels, the wheels are rotatably arranged on two sides of the main body, the main body is provided with a damping clamping part clamped with or separated from the sliding block, and the damping clamping part is concavely arranged on the upper end surface of the main body; the pulley still has two fixed plates, is located the double-phase relative lateral surface of main part respectively, and the wheel is installed and is leaned on along the side at the fixed plate.
