Description

Slide rail hydraulic reset device

Technical field:

The utility model relates to the technical field of slide rail devices, in particular to a slide rail hydraulic reset device.

Background technique:

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 will be larger, so the friction will be larger, resulting in the drawer not moving smoothly, and due to the large sliding friction, the sliders will be worn 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 way of replacing sliding friction with rolling friction makes the opening and closing of the drawer much more convenient and smooth.

The Chinese patent application with the patent number 200720057529.2 discloses a hydraulically resettable slide rail device with hidden rollers, which includes: outer rails and inner rails nested together, wherein the outer rails and inner rails are nested through roller brackets It also includes a reset slider, a hydraulic damping piston, a fixed cover and a tension spring that constitute a hydraulic reset device; one side of the reset slider is clamped between the inner rail and the outer rail, and the other The side sliding is set in the fixed cover plate fixed on the inner groove surface of the outer rail; one end of the inner side of the inner rail is provided with a dial to toggle the reset slider, and the reset slider is provided with two bumps for clamping the dial. The reset slider is connected to the outer rail through a tension spring, the hydraulic damping piston is fixed on the inner groove surface of the outer rail, and the output end of the hydraulic damping piston is connected to the reset slider through a pull hook.
