Background technology
Railroad is the device that a kind of quilt extensively uses, and is generally used for connecting two article that relative motion can take place each other, particularly wherein one by slide rail carrying or support another person's occasion, for example drawer, cabinet-type servomechanism etc.
Common railroad has the bipartial slide rail, general bipartial slide rail generally includes one first slide rail and one second slide rail, with the drawer is example, its first slide rail is fixed on the bracing frame, its second slide rail then is fixed in the both sides of drawer, uses ball bearing to be coupled between first slide rail and second slide rail, and makes second slide rail to slidably reciprocate with respect to first slide rail along the axis direction of first slide rail, therefore, drawer just can freely be drawn out or push back by slide rail.
This also necessary a kind of positioner of needs of bipartial slide rail that comprises first slide rail and second slide rail, when drawer is drawn out, drawer can be positioned at a suitable position and be unlikely to drop or return, and in the time of needs, can also and be reinstalled the dismounting of drawer self-supporting frame.
A kind of railroad of industry appearance at present, comprise that one first slide rail, one second slide rail, are articulated in clamping piece and on this second slide rail and are fixed in barrier sheet on this first slide rail, this clamping piece is offered a breach, this barrier sheet is fastened in the breach of this clamping piece railroad is carried out two-way location, during release, pull this clamping piece and make its breach and this barrier sheet break away from fixing, and then with the railroad release.But this railroad can only the two-way simultaneous release when release, uses inconvenient.
Summary of the invention
In view of above content, being necessary to provide a kind of can carry out two-way location and railroad that can unidirectional release to slide rail.
A kind of railroad, comprise that one first slide rail and is slidingly fastened in second slide rail of described first slide rail, on described first slide rail two stop parts are set, described railroad also comprises two keepers, activity is installed in one first unlock piece of described second slide rail and the flexible member that one second unlock piece and is installed in described second slide rail, described second slide rail is fixed with a fixture, two chutes offered by described fixture so that described two keepers can be distinguished slip therein, described two keepers can be respectively fasten with described first slide rail in two-way location and described second slide rail with two stop parts of described first slide rail, when described first unlock piece pushing and pressing in described two keepers that moves along the described second slide rail longitudinally makes it when being different from described longitudinally and sliding, a disengaging in described keeper and described two stop parts is fastened and described first slide rail of release and described second slide rail, when described second unlock piece pushing and pressing another in described two keepers that move along the described second slide rail longitudinally makes it when being different from described longitudinally and sliding, another disengaging of described keeper and described two stop parts is fastened and described first slide rail of release and described second slide rail, and the two ends of described flexible member can push against described two keepers respectively resets described two keepers.
Compare prior art, described railroad utilizes two keepers and two block pieces that described first slide rail and described second slide rail are positioned, utilize two unlock pieces that described two keepers are moved with described first slide rail of release and described second slide rail, not only realize two-way location and can unidirectional release, simple in structure, easy to use.
