Top suspension door rail for storage cabinet

Abstract

The invention discloses a top suspension door rail for a storage cabinet. The top suspension door rail comprises a groove-shaped upper rail. At least two pulley guide rails for mounting door pulleys are vertically parallelly arranged in the groove-shaped upper rail and are arranged along the length direction of the upper rail, the lower end of each pulley guide rail is upwardly bent towards the same side to form a pulley support rail, a plurality of pulley mounting holes are formed in the upper rail at intervals and are formed in the bottom of a groove, which is formed in a position above the pulley guide rails, of the upper rail, and an ascending separation preventing device for preventing the corresponding door pulley from being separated from the corresponding pulley support rail is mounted at each pulley mounting hole. The top suspension door rail has the advantages that the ascending separation preventing devices are arranged at the pulley mounting holes to prevent derailing phenomena of the pulleys at the pulley mounting holes, accordingly, the derailing phenomena due to ascending of the pulleys can be prevented, and the pulleys can stably run on the pulley support rails.

Description

Technical field [0001] The invention relates to the technical field of storage cabinets, in particular to an upper-hung door track for storage cabinets. Background technique [0002] The original sliding doors were only used for the sliding doors of bedroom or dressing room wardrobes, but with the development of technology and the diversification of decoration methods, from traditional sheet surfaces to glass and aluminum alloy profiles, from sliding doors, folding doors to partitions The function and use range of doors and sliding doors are constantly expanding. In this case, the use of sliding doors began to become diverse and abundant. In addition to the most common partition doors, sliding doors are widely used in bookcases, wall cabinets, living rooms, exhibition halls, sliding doors, etc. [0003] The wood panels used for sliding doors (mainly fiberboard and particleboard) are man-made panels, and the adhesives used contain harmful substances such as formaldehyde.

AI Technical Summary

Problems solved by technology

Metal pulleys are strong but prone to noise when in contact with the track

The wheels of some low-grade sliding doors are made of organic plastics, which are easy to wear and deform. Over time, they will fluctuate when pushed and pulled. The open wheel structure is easy to get dust and wear the internal bearings.
