Description
Technical field
The present invention relates to slide rail field, be specifically related to a kind of slide rail of overtravel anti-rock.
Background technology
The anti-rock slide rail of prior art is as CN102644661A, it discloses a kind of slide rail anti-rock lazy-tongs, realize left and right slide rail by the tooth bar be arranged on two wood side-guides and the gear be connected for a pair be engaged on tooth bar synchronously pull out and regain, avoid two wood side-guides asynchronous and the pause and transition in rhythm or melody sense of generation, make slip more smooth-going, improve the feel that slide rail uses.
But, when needs slide rail is opened completely and is made interior rail exceed outer rail, namely when overtravel, because single tooth bar length can not be greater than slide rail entire length, the anti-rock synchronizing function of this type of slide rail is subject to the restriction of tooth bar length, in total travel, realize rocking-proof function at the most, rocking-proof function can not be realized within the scope of overtravel.
Existing patent is a kind of slide rail realizing overtravel rocking-proof function as CN102469879A discloses, but owing to taking the space of vertical direction when secondary tooth bar is regained, thus limit the length of secondary tooth bar.
