Adjustable damping system for sliding rail

Abstract

The invention provides an adjustable damping system for a sliding rail. The adjustable damping system comprises a damping shell, a slider, a rotating pull block, a buffer cylinder, a tension spring, an adjusting part, an adjusting nut and a guide wheel, wherein the adjusting part can adjust the tension of the tension spring on the slider, and the buffer cylinder is embedded into the damping shell.A wheel axle of the guide wheel is rotatably connected to the upper end of the damping shell, the lower end of the damping shell is provided with a guide sliding strip, the slider and the rotating pull block are embedded into the guide sliding strip and slide along the guide sliding strip, the rotating pull block is rotatably connected onto the slider, the end of a piston rod of the buffer cylinder is clamped onto the slider, the adjusting part comprises a connecting portion at the front end and a screw rod in threaded connection with the adjusting nut, the damping shell is provided with a sliding groove, a connecting portion slides in the sliding groove, one end of the tension spring is clamped onto the slider, and the other end of the tension spring bypasses the guide wheel and then isclamped onto the connecting portion of the adjusting part. The adjusting part is matched with the adjusting nut and drives the connecting portion to slide along the sliding groove, so that the tensionof the tension spring is increased or decreased.

Description

technical field [0001] The invention belongs to the technical field of slide rail drawers, and relates to an adjustable damping system for slide rails. Background technique [0002] The adjustable damping system of the slide rail is mainly used on the slide rail drawer. Its function is that when the drawer is closed to a certain distance, the buffer cylinder provides a certain resistance, so that the drawer can be closed slowly, and the resistance of the buffer cylinder increases as the drawer moves forward; At the same time, the tension spring can prevent the drawer from opening automatically, and the tension spring pulls the drawer inward to overcome the resistance of the buffer cylinder. [0003] For example, the invention patent with application number 201120032838.0 provides a self-closing buffer assembly for drawer rails, which includes a self-closing box, a self-closing touch piece, a self-closing shaft, a buffer oil cylinder, and a tension spring. The pin, the runne...

Problems solved by technology

[0004] However, the end of the tension spring of the above-mentioned self-closing buffer assembly is fixed on the self-closing box, and the tension of the tension spring cannot be adjusted, resulting in low practicability. An assembly of the same specification cannot be used for drawer slide rails of various specifications.
