Abstract
The utility model relates to a slide-way, in particular to a three-section anti-return checking slide-way comprising an inner track, a middle track, and an outer track. The slide-way is provided with a rear bolting device comprising a stopping piece and a locking piece, wherein, the stopping piece is arranged on the outer track and is provided with two opposite stopping faces between which a space is arranged; the locking piece comprises two locking plates in a flanning butt clamp, the locking plates are pivoted at one end of the middle track towards the outer track and are connected with each other through an elastic element, the angle between the two locking plates can flexibly open and close, the broad end of the angle is farther than the space between stopping faces, and the narrow end of the angle is closer than the space between the stopping faces and faces to the outer track; when the slide-way is spread, the locking plates can be just propped up by the stopping faces of the stopping piece so as to glide through, and the reclosed locking plates butt against the stopping faces again so as to realize bolting. The bolting structure is simple and reasonable, cannot easily deform, and ensures the bolting on all sections to be more successfully and tightly; the middle track can only be unbolted on the premise that the inner track is retracted, the security is increase, and the accidental jammed injury can be effectively prevented.
Description
Technical field
The utility model relates to a kind of slide rail, and particularly a kind of syllogic that includes interior rail, middle rail, outer rail that is used in is prevented back sliding screens slide rail.
Background technology
Slide rail is a kind of device that is widely used in many equipment or the article, normally in order to connect two article that relative motion can take place each other, particularly wherein one will or support another person's occasion by the slide rail carrying, for example cabinet and drawer thereof, computer desk and keypad support plate thereof, or other analogs.
General slide rail is generally the three-member type slide rail that includes an interior rail, a middle rail and an outer rail.With the slide rail that is used in cabinet and drawer thereof is example, outer rail wherein is fixed in cabinet, interior rail then is fixed on the both sides of drawer, in rail be incorporated among the described outer rail in order to bear described in rail, above three is coupled to each other by a kind of coupling means (normally a kind of design of ball bearing), and make described in rail and described in rail can do moving back and forth with respect to described outer rail along identical axis direction.Therefore, described drawer just can be collected by the inside that described slide rail freely is drawn out described cabinet or is pushed back described cabinet.
This three-member type slide rail that includes outer rail, middle rail and interior rail also needs a kind of design of bolt-lock, when being put in order to be stretched to full exhibition position fully at slide rail described slide rail is maintained this position.Because be normal use location by the position of the middle rail of bolt-lock and outer rail this moment, so the latched position that is called as full exhibition is put in this full exhibition position.
No. 01201593.8 patent disclosed at Chinese patent is a kind of slide rail that includes interior rail, middle rail and outer rail equally, wherein disclosed a kind of locking mechanism, described locking mechanism can be drawn out to the latched position of a full exhibition by rail in described and rail in described be remained on the latched position of described full exhibition, after rail was retracted in described, described locking mechanism also can be released.Described locking mechanism includes block piece, a locking plate and a releasing unit that is fixed on outer rail.Described locking plate has a shovel shaped nose and a trigger.When the latched position of described full exhibition, described shovel shaped nose withstands described block piece, thereby rail and outer rail is mobile in stoping; When rail was retracted in described, described releasing unit spurred described trigger, thereby described shovel shaped nose is pushed away described block piece, to discharge described locking mechanism.Yet, because the trigger of described locking plate is not had fixing draw direction and easy deformation by deflection, therefore being not easy successfully to be spurred, and then causing discharging described latch-up structure failure by described releasing unit, described interior rail can not successfully be regained.
