Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a vertical load-bearing slide rail. Background Technique

[0002] A vertical load-bearing steel ball slide rail is a slide rail that uses high-precision steel balls as rolling elements. Generally, a bead sheet is embedded in the outer strip of the slide rail to fix the steel balls on both sides. The moving part is placed on the bead sheet, and the moving part slides back and forth through the rolling of the steel balls. It is mostly used in cabinets, wardrobe drawers, toolboxes, tool cabinets, fire trucks, etc.

[0003] The existing vertical load-bearing slide rail consists of an outer fixed rail, an intermediate fixed rail, and an inner fixed rail. Relative sliding between the fixed rails is achieved through precision steel balls. The overall structure is a mutually wrapped structure, that is, the outer fixed rail wraps the intermediate fixed rail, and at the same time, the intermediate fixed rail wraps the inner fixed rail. In the installation of some existing vertical load-bearing slide rails, the inner fixed rail is directly locked to the drawer by screws, and at the same time, the outer fixed rail is locked to the cabinet body. When the screws are installed horizontally, they need to bear too much supporting force, and the drawer is prone to unstable operation during long-term use. Therefore, a vertical load-bearing slide rail is proposed to solve the above problems. Content of the Utility Model
