Description

Synchronous locking mechanism of slide rail

This creation is used in the field of industrial computer cabinets, especially a synchronous locking mechanism for slide rails. During operation, it can use the inner rail to drive the middle rail and the outer rail to synchronize sliding, and prevent the middle rail from operating first. Slider.

Press to mention all furniture, desks, cabinets or industrial computer cabinets, etc., which are divided into movable parts (drawers or cabinets) and fixed parts (body), by which the movable parts can reciprocate relative to the fixed parts And achieve the purpose of storage or use. In order to improve the smoothness of the movable part during its movement, a slide rail is generally installed between them. Such slide rails can be divided into two-stage slide rails and three-stage slide rails according to the unfolded length. The three-stage slide rail is used as For example, it is composed of an outer rail, a middle rail, an inner rail, and two sliding aids. The outer rail is usually fixed on a fixed part, the inner rail is fixed on a movable part, and the middle rail is By using the sliding member such as ball bearings or rollers to be connected between the outer rail and the middle rail, and between the middle rail and the inner rail, the inner rail and the middle rail can be along the same The axis direction makes a reciprocating push-pull movement relative to the outer rail. This three-stage slide rail can be used for large-scale pull-out and income movement, and it also saves space after storage, so it is often used.

However, the biggest problem encountered with this type of three-stage slide rail is that during operation, the inner rail, the middle rail and the outer rail cannot be moved in a certain order due to the driving of the sliding aids, so they often The problem of unsmooth sliding occurs, so most of the slide rails will be designed with synchronization mechanism, When the slide rail is fully pulled out to the full exhibition position, the middle rail can be positioned at the limit when the stretching action is performed, and the positioning state of the middle rail is released at the same time when the inner rail is folded, to The middle rail can be synchronized with the income, such as the Republic of China invention patent I251479 "three-stage slide synchronization device", I285538 "three-stage slide synchronization device", I421049 "slide assembly and its connection structure ", I563944 "slide rail mechanism", I624236 "sequential pull-out structure of slide rail opening", etc., all disclose that the inner rail can be brought out synchronously with the middle rail, thereby reducing the bearing of the middle rail when it is pulled out Synchronization device or slide rail structure for loading stress to increase the service life of the slide rail. However, its lack is that most of them are only synchronized for the operation of pulling out, and there is no synchronization effect for the operation of pushing in and storing, so that the middle rail may still be damaged by a great torque during the pushing process. Moreover, it has been proved that the damage condition at the junction between the middle rail and the inner rail is the most obvious. Therefore, how to make the middle rail and the inner rail perform a two-way synchronous action is a difficult problem for the industry to overcome.

Therefore, the author devotes his efforts to research a synchronous locking mechanism of the slide rail, which has the function of two-way synchronization, and improves the smoothness and stability of its use through the mutual relationship during its operation, greatly reducing the middle rail The load stress it bears when it is pulled out to extend its service life.
