Description

Single spring buffer slide rail Technical Field The utility model relates to the field of sliding rails, in particular to a single spring buffer sliding rail. Background Along with the progress of society, various devices which are convenient for people to live are greatly developed, and a slide rail buffer is a device for buffering pressure, for example, when a drawer is pushed in and closed, a buckle piece at the front end of a rail in a three-section steel ball slide rail triggers a lock catch switch on a damper, a compression spring releases tensile deformation energy to drive the slide rail to enter the damper, the damper starts to operate, so that the drawer generates resistance at the moment of closing, the slide rail is prevented from generating impact and noise, and meanwhile, vibration generated by closing the drawer by huge external force is avoided. However, the traditional single-spring sliding rail relies on single spring stiffness to realize buffering, and the spring is easy to generate plastic deformation after long-term high-frequency use, so that elastic potential energy is reduced, buffering force is attenuated, frequent replacement is needed, and the use cost is high. Accordingly, a single spring cushioned track is provided by those skilled in the art to address the problems set forth in the background above. Disclosure of utility model The utility model aims to solve the defects, and provides a mechanism for adjusting the extrusion spring, which solves the problems that the spring is easy to generate plastic deformation after long-term high-frequency use, the elastic potential energy is reduced, the buffering force is attenuated, frequent replacement is needed, and the use cost is high in the prior art. The object of the utility model is achieved by: The utility model provides a single spring buffering slide rail, includes outer rail, well rail and interior rail, well rail sets up between outer rail and interior rail, and the one end of outer rail is installed and is turned to the nail, and one side of turning to the nail is provided with fixed cover, and the opposite side of turning to the nail is provided with the stop collar, install the buffer in the fixed cover, the locating hole has been seted up on the both sides wall of stop collar, has inserted first spring in the stop collar, and first spring is in the one end of stop collar and installs a spacing section of thick bamboo, and the movable groove has been seted up to the upside of a spacing section of thick bamboo, first driving lever is installed to one side of movable groove, open the groove has been seted up on the left and right sides wall of a spacing section of thick bamboo, the draw-in groove has transversely been seted up to one end inner wall that a spacing section of thick bamboo kept away from first driving lever, the sliding plug has the depression bar in the spacing section of thick bamboo, and the second driving lever is installed to the upper end of depression bar, the depression bar has the second spring to plug in the one end of propping the depression bar towards first spring, installs the connecting piece, has rotated the connecting rod from top and has cup jointed in the connecting piece in the one end of connecting rod, one side of keeping away from the connecting rod and has rotated the connecting rod and has installed the fixture block.
