Description

The buffer gear of slide rail return device

Technical field

The utility model relates to a kind of buffer gear of slide rail return device, and You Zhike significantly simplifies the structure complexity of this buffer gear and accelerates assembling speed, so can reach designs simplification, assembling fast with the buffer gear of the effect that reduces cost.

Background technology

The buffer gear that generally is used for sliding track mechanism or slide rail return device; According to the source of its internal damping resistance, can generally be divided into oil hydraulic type or vapour-pressure type, just use fluid such as liquid (being oil hydraulic type) or gas (being vapour-pressure type) that the effect of buffering damping is provided; The fender pile that this kind commonly used; Except structure is comparatively complicated, the problem of leakage of oil or gas leakage is also arranged easily, and then cause the maintenance inconvenience last with cleaning.To aforementioned disappearance; Industry also has the mode that makes side wall surface generation friction within a rubber damping and the hollow tube of using instead; Required cushion effect is provided,, sees also shown in first figure like Taiwan patent gazette M377463 number " the fender pile structure of convenient assembling "; It is to be made up of a hollow tube 11, an axle center 12, an

installation shaft

14 and 13 of damping units; Wherein this axle center 12 is to be installed in this hollow tube 11 versatilely and its top exposes to this hollow tube, and these installation shaft 14 its front ends are installed in the bottom in this axle center 12, and this damping unit 13 is to be made up of padded coaming such as rubber or expanded material in addition; These damping unit 13 its front end sleeves are held before being located at this installation shaft 14; These damping unit 13 its rear end have an outstanding sliding part 131, again these axle center 12 1 ends usually the sliding track mechanism or the slide rail return device of system and outside connect, by this; And make this axle center 12 can be with this sliding track mechanism or slide rail return device interlock; And for example this case creator has applied for Taiwan patent application case on record number No. 100216920 " the location return device (two) of slide rail ", promptly once discloses the embodiment that a slide rail return device combines with the fender pile of commonly using, in order to do when this slide rail return device returns, obtaining buffering to lower collision or noise; Operating principle that should the fender pile structure of assembling " convenient " its buffering effect be utilize this axle center 12 can be along with the unlatching of railroad relatively this hollow tube 11 outwards slide; In order to do when this railroad folds; Inwardly slide in 12 in this axle center this hollow tube 11 relatively; And these damping unit 13 its sliding parts 131 promptly can with wall friction within this hollow tube 11, this damping unit 13 can be stopped slightly compressive strain because of this sliding part 131, and it is radially slightly expanded; And make this damping unit 13 can be resisted against side pipe wall within this hollow tube 11; And can produce and provide a cushion effect, in order to do can making this railroad when returning, reach the effect of buffering, and then make and should " fender pile structure of facility assembling " can reach the purpose that buffering effect is provided.It is somebody's turn to do " the fender pile structure of convenient assembling " though can reach the purpose that buffering effect is provided; But it must be formed by multiple textural associations such as hollow tube 11, axle center 12, installation shaft 14 and damping units 13; Must footpath outside damping unit 13 its sliding parts 131 be controlled at simultaneously and be slightly larger than footpath within this hollow tube 11; Can in action, produce rubbing action to reach buffering effect; Therefore its overall structure is very complicated, and the Mold Making precision requirement is higher, causes the product action to have some setbacks like the Mold Making error easily when big and maybe can't reach the buffering effect of ideal; And then it is lower to cause time-consuming, the processing procedure cost of assembling to improve with production reliability, and historical facts or anecdotes has necessity of improvement.
