Description

Return buffer

Technical field

The utility model relates to a kind of recurrence buffer, and You Zhike avoids slide mechanism to go into dirt and automatically returns disabler, but and stroke is stable, and then can promote the recurrence buffer of product application life and production reliability.

Background technology

General recurrence buffer; Applied for tw Taiwan patent application case on record number No. 100216920 " the location return device (two) of slide rail " like this case creator; See also shown in Figure 1; It comprises: a holder 11, this holder 11 can supply to be arranged in its external slide rail of sliding track mechanism, and wherein this sliding track mechanism still can include a slide rail and an interior slide rail in one; Know owing to possess common knowledge the knowledgeable in the technical field under thin portion structure of this sliding track mechanism and operating principle are, give unnecessary details no longer in detail in this; One slide mechanism 12; This slide mechanism 12 wears with this holder 11 mutually; And be connected with elastic component 17 between this slide mechanism 12 and the holder 11, this slide mechanism 12 is provided with sliding axle 13, and this slide mechanism 12 is provided with release piece 14 again; These release piece 14 1 ends and this sliding axle 13 are coupling, and these release piece 14 other ends are provided with a Passive part 141; One plectrum 15, this plectrum 15 are arranged on this holder 11, and its interior slide rail of this plectrum 15 and this sliding track mechanism sets firmly mutually, and this plectrum 15 is provided with notch portion 16 again, and these plectrum 15 its notch portion 16 fasten the Passive part 141 of these slide mechanism 12 its release pieces 14; Its principle system utilizes when pulling out or pushing back this sliding track mechanism; Its interior slide rail of this sliding track mechanism can drive this plectrum 15 horizontal shifts; In order to do making this plectrum 15 can drive this release piece 14 its Passive part 141 rotational displacement; Switch separating or combines and fastening of this plectrum 15 and these release piece 14 its Passive parts 141 and can control, thereby stretchings of changeable this slide mechanism 12 located or recurrence resets, and then can reach and make this sliding track mechanism can locate the purpose of recurrence automatically.

Be somebody's turn to do " the location return device (two) of slide rail "; Though can reaching, it make this sliding track mechanism can locate the purpose of recurrence automatically; But when these slide mechanism 12 starts were shifted as stretching, its most of parts and this elastic component 17 all can all or part ofly be exposed to outside this holder 11, and make this sliding axle 13 and elastic component 17 or have the parts of lubrication oil to become easily infected by dust on other; Cause mechanism action to have some setbacks and influence life of product, and then cause and use last puzzlement and life of product reduction; In addition; This holder 11 does not have any mechanism design that guides or limit these plectrum 15 displaced path; Therefore when this plectrum 15 drives these release piece 14 displacements, this plectrum 15 be easy because of and this release piece 14 between interaction force, and this plectrum 15 squinted or break away from normal path of motion; Cause these plectrum 15 its notch portion 16 no longer to fasten mutually with these release piece 14 its Passive parts 141; Cause it to locate automatically and return disabler, and then cause and use inconvenience and production reliability to reduce, therefore improved necessity arranged in fact.

Summary of the invention
