Concealed roller hydraulic replacement three-fold sliding track

Abstract

The invention relates to the technical field of slide rail apparatus, in particular to a hidden type rolling shaft hydraulic reset three breaking slide rail, comprising an outer rail, a middle rail, and a inner rail; one side edge of the outer rail is embedded and connected with the middle rail through a rolling shaft bracket; the inner rail is embedded on the middle rail, comprising a reset sliding block, a hydraulic damping piston, a fixed cover plate and a draught spring; the fixed cover plate is fixed on the inner groove face of the outer rail, one side of the reset sliding block is sliding slipped in the spacing gap between the middle rail and the outer rail, the other side is sliding slipped in the fixed cover plate; a dialing post for poking the reset sliding block is arranged at one end of the lateral face of the middle rail, two projection for clipping the dialing post are positioned on the reset sliding block, a reset stop block is arranged at one end of the reset sliding block, a reset opening is positioned at the counterpart end of the fixed cover plate; one end of the draught spring is fixedly connected with the reset sliding block, the other end is fixed in the jaw on the inner groove face of the outer rail. The slide rail apparatus has the advantages of smooth expansion, balancing operation, long service life and low noise.

Description

Technical field: [0001] The invention relates to the technical field of slide rail devices, in particular to a three-fold slide rail with hidden roller hydraulic reset. Background technique: [0002] Slide rails are designed to realize the relative movement of two adjacent objects. For example, in desks used by people, the opening and closing of drawers is mostly realized through this slide rail device. The early slide rail device mainly includes two slide bars respectively arranged on the table and the drawer, wherein the slide bar arranged on the drawer will slide along the slide bar fixed on the table. To overcome the sliding friction between the sliders, if the joint surface between the sliders is not smooth enough, the friction coefficient is large, so the friction is large, causing the object to move unsmoothly, and due to the large sliding friction, it will cause the slider to wear Faster, resulting in shortened product life. In response to the above situation, peop...

Problems solved by technology

The early slide rail device mainly includes two slide bars respectively arranged on the table and the drawer, wherein the slide bar arranged on the drawer will slide along the slide bar fixed on the table. To overcome the sliding friction between the sliders, if the joint surface between the sliders is not smooth enough, the friction coefficient is large, so the friction is large, causing the object to move unsmoothly, and due to the large sliding friction, it will cause the slider to wear Faster, resulting in shortened product life

In response to the above situation, people have improved the design, such as setting a roller device between the slide bars. This method of replacing sliding friction with rolling friction makes the opening and closing of the drawer much more convenient and smooth, but the stability of its structure is still not enough. Very good, but the bearing capacity is poor, and this early slide rail is not equipped with a reset device, the slide rail can slide freely in both directions along the track, when a certain pulling force is applied from the outside world or under the action of gravity on an inclined plane, the drawer will stretch out from the table. In this way, the drawer is in a very unstable state, and any small external changes will cause it to slide, so that the user must repeatedly close it, or need to use a key to fix it relative to the table body, these bring some troubles to users
