Description
Affiliated technical field
The utility model relates to furniture part, particularly with the drawer guideway of forced locking device.
Background technology
At present, the drawer of various desks has all been installed the drawer guideway that slides freely.Can be close to desk for after drawer is closed, neat appearance seems.The method of prior art is to adopt the angle type guide rail of pass certainly of international design, be provided with one section guide rail that tilts a little downwards in the rear end of retaining rail, when allowing the front wheel that is contained in the slip rail on the drawer run to tilting section under the effect of deadweight automatically toward gliding, thereby guarantee that drawer closes fully.Yet this close the angle type guide rail exists following weak point always certainly:
1, when the roller of slip rail is pushed into the downslide end, the deadweight of depending merely on drawer makes roller have only 2.5 °-3 ° inclined-plane to glide, and downslide is closed not obvious, and result of use is very undesirable.
2,,, just the situation that skids off and fall on the ground is arranged when drawer outwards slightly tilts because crooked angle is little.
3, because structural reason, when fixed rack is crooked, can not connect smooth-goingly at bending point, so during the drawer push-and-pull, the sensation of the back descending that goes up a slope is always arranged, be difficult to satisfy user's requirement like this.
Summary of the invention
The purpose of this utility model is to solve the deficiency of existing drawer guideway, provides a kind of drawer that can guarantee to fasten automatically, is not easy the outwards drawer guideway of the band forced locking device of slip.
Task of the present utility model realizes by this way: this drawer guideway includes retaining rail and slip rail, it is characterized in that in the rear end of retaining rail, also being provided with one by sliding chute seat, slide block, the forced locking device that spring lever and spring constitute, sliding chute seat is one and places the bottom surface in the retaining rail rear end to open wide, the cuboid that end face flushes with retaining rail, its end face have a front end have one vertically downward the section L type horizontal concrete chute, slide block is close to the horizontal concrete chute bottom surface, be provided with one and horizontal concrete chute matched cylindrical guiding plush copper at its end face, spring lever is supported on the through hole of the slotted hole of sliding chute seat rear end face and slide block rear end face, spring is arranged on the spring lever between slide block through hole and the spring lever end of stroke, is provided with an arc guide groove that cooperates with the guiding plush copper in the rear end of slip rail.
The purpose of this utility model also will take following measure to realize:
Described forced locking device is to cooperate the rear end that tightly places retaining rail with each two outer lug that are provided with of sliding chute seat end face both sides concave indentation corresponding with retaining rail.
Also be provided with the elastic buffer sheet of an arc at the front end of sliding chute seat,, play cushioning effect, reduce strike note so that when drawer moves to closed condition toward in, allow the elastic buffer sheet contact with the roller of slip rail.
On the sliding chute seat below the second half section of chute, also have a wedge type groove that is communicated with runner rear end, make the bottom surface of chute second half section form the state that suspends, can produce certain elastic deformation, help spring lever up to move.
The utility model is work like this: as prior art, retaining rail is installed on the drawer next door during use, the slip rail is installed on the drawer side wall.When closing drawers, the slip rail inwardly slides with advancing along retaining rail in the drawer, when the deep-slotted chip breaker of slip rail front end with after the guiding plush copper of slide block contacts, the guiding plush copper that is positioned at the horizontal concrete chute vertical section just moves up along arc guide groove.When moving to horizontal segment, the guiding plush copper is unfettered, and the spring that has compressed just discharges elastic force, drives the slip rail and slides to the bottom rapidly together with drawer, and be in tight configuration state under the spring force effect, thereby drawer is locked.When people pull out drawer, move association at the protruding ice of guiding of the effect sliding block of pulling force outward with the camber gathering sill of slip rail, when moving on to the horizontal concrete chute front end, can not move forward again, and the slip rail also continues to move outward, the guiding plush copper is depressed in the straight section that lets droop of horizontal concrete chute front end, the camber gathering sill breaks away from the guiding plush copper to be continued to move outward with the slip rail, and drawer is drawn out.Meanwhile, along with the guiding plush copper moves outward, slide block constantly compresses the spring of spring lever, fall into the straight section that lets droop of horizontal concrete chute front end to the plush copper that leads after, slide block just is fixed in herein, spring is in compressive state.When closing drawers, repeat above-mentioned moving process again.In above-mentioned slide block moving process, spring lever also can moving up and down and move up and down with slide block, therefore the effect that is provided with slotted hole at the rear end face of sliding chute seat is to be convenient to spring lever and moves up and down, and the suspend design of state of horizontal concrete chute second half section bottom surface is to allow its elasticity help spring up to move mutually.
From structure of the present utility model and operation principle as seen, the utlity model has following advantage:
1, because the utility model is to utilize the elastic force of spring to realize that drawer closes automatically, can guarantee that drawer fastens automatically, be not easy outwards to skid off.
2, the drawer push-and-pull is very smooth-going, and feel is fairly obvious when closing.
3, novel in design, simple in structure, install and use very convenient.
