Buffer mechanism for slide rail returning device

Abstract

The invention discloses a buffer mechanism for a slide rail returning device. The buffer mechanism comprises a slide rail returning device and a buffering mechanism; the slide rail returning device is provided with a fixed seat, a slide mechanism and a poking piece; the slide mechanism can be arranged in an accommodation space of the fixed seat in a sliding way; the slide mechanism comprises a release piece; one side of the release piece is further provided with a pressing part; the poking piece is overlapped with a groove of the fixed seat; the buffering mechanism is sleeved with the slide mechanism and can be arranged on one side of the inner side wall of the accommodation space in a sliding way and is positioned between the pressing part of the release piece and the inner side wall; the buffering mechanism directly rubs the slide rail returning device, so a buffering effect can be achieved; and therefore, the effects of simplifying the structure, quickly assembling the buffer mechanism and reducing cost can be achieved.

Description

Technical field [0001] The invention relates to a buffer mechanism of a sliding rail return device, in particular to a buffer mechanism that can greatly simplify the structural complexity of the buffer mechanism and accelerate the assembly speed, thereby achieving the effects of simplified structure, rapid assembly and cost reduction. Background technique [0002] Generally used for sliding rail mechanism or sliding rail return device buffer mechanism, according to the source of its internal buffer resistance, it can be divided into oil pressure type or pneumatic type, that is to use fluid such as liquid (ie oil pressure) or gas (ie Pneumatic type) to provide cushioning and damping effects. In addition to the more complicated structure of this conventional cushion rod, it is also prone to oil or air leakage problems, which in turn leads to inconvenience in maintenance and cleaning. In response to the aforementioned shortcomings, the industry has also switched to the method of fri...

Problems solved by technology

Although the "buffer rod structure for convenient assembly" can achieve the purpose of providing a buffer effect, it must be composed of various structures such as a hollow pipe body 11, an axis 12, an installation axis 14, and a damping unit 13. At the same time, it must The outer diameter of the sliding part 131 of the damping unit 13 is controlled to be slightly larger than the inner diameter of the hollow tube 11, so that friction can be generated during the action to achieve a buffering effect. Therefore, the overall structure is very complicated, and the precision of the mold making requires Higher, if the mold manufacturing error is large, it is easy to cause the product to not move smoothly or not to achieve the ideal cushioning effect, which will lead to time-consuming assembly, increased process cost and low product reliability, so it is necessary to improve
