Description

Technical Field

[0001] The utility model relates to the technical field of slide rails, in particular to a slide rail locking structure. Background Art

[0002] Slide rails, also known as guide rails and slideways, refer to hardware connection components fixed to the cabinet body of furniture for the movement of drawers or cabinet panels of furniture. Slide rails are suitable for drawer connections of wooden and steel drawers in cabinets, furniture, document cabinets, bathroom cabinets and other furniture. If the hinge is the heart of the cabinet, then the slide rail is the kidney. Whether those large and small drawers can be pushed and pulled freely and smoothly, and how they bear weight, all depends on the support of the slide rails. From the current technology, the bottom slide rail is better than the side slide rail, and the overall connection with the drawer is better than the three-point connection. The materials, principles, structures, and processes of drawer slides vary greatly. High-quality slide rails have low resistance, long life, and smooth drawers.

[0003] The existing slide rail locking structure cannot flexibly fix the slider on a certain section of the slide rail, making the slide rail insufficiently flexible, and the general slide rail lock is complicated to operate. Most existing slide rails achieve the closed locking of the slide rail through a plastic part at one end of the slide rail. This plastic part fails after being used for a period of time, causing the slide rail to automatically slide out easily, which is inconvenient to use. Utility Model Content
