Technical field
The utility model relates to a kind of slide rail that is used to support drawer class article, particularly a kind ofly is used for that drawer supports, three joint slide rails of fixing, pull.
Background technology
At present, often the slide rail that uses mainly contains two joint slide rails and three joint slide rails, is installed in the products such as family's kitchen cabinet, furniture, desk and drawer type household electrical appliances.Two joint slide rail products wherein can't make drawer integral body all be drawn out, and have tangible weak point, and three joint slide rails can address this problem effectively, whole drawer integral body can be pulled out, and therefore are subjected to application more and more widely.Particularly in the furniture and electric equipment products of top grade, use three joint slide rails more, to make things convenient for depositing of article.
Three joint rail structures mainly comprise rail, middle rail and following rail (also being called interior rail, middle rail and outer rail), adopt sliding friction or ball rolling friction connected mode between the contacted slide rail.Disclose a kind of " heavy load steel profile three stage ball railing " as CN03220248.2, interior rail, middle rail, outer rail and the ball made by the drawn steel section bar constitute.Outer rail is nested with middle rail, the cross sectional shape of middle rail, outer rail is: the cross sectional shape up and down of rail or outer rail is an arc at least, and outer rail up and down inner face and middle rail is provided with the slide groove of two and half arcs outside up and down, be provided with the ball of rolling in the slide groove, rail during the cross section of the curve form in interior rail cross section and the band deep-slotted chip breaker of middle rail matches and embeds.This three joints supporting between guide rail only realizes by several balls, has therefore that push-and-pull has some setbacks, friction noise big and move jiggly defective and deficiency.CN200820238494.7 discloses a kind of three-section type metal drawer slide rail, comprise the metal side plate that can be connected with drawer-bottom board, panel and back plate, the movable rail, the retaining rail that are slidingly matched with metal side plate, be located at and hinder the elasticity screens glue that metal side plate is slided and on the movable rail, be located at the roll wheel assembly more than two on the movable rail; Movable rail is by establishing roll wheel assembly and the retaining rail slip that cooperatively interacts thereon, is being provided with the anti-drop block that the both ends roll wheel assembly that prevents on the movable rail is deviate from the retaining rail.Above-mentioned three joint slide rails can not automatically reset, and have certain inconvenience in the use.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of three joint slide rails, guaranteeing on the basis that guiding is accurate, realization drawer integral body is pulled out, quiet run, automatically reset three joint slide rails can be realized, high-grade kitchen cabinet, top-grade furniture, high-grade desk and relevant electric equipment products etc. can be used for.
The utility model three joint rail structures comprise following content: three joint slide rails comprise rail, middle rail and end rail, middle rail has two supporting planes is installed, be that supporting plane is installed on top and supporting plane is installed in the bottom, installed on the supporting plane on rail top during last rail was sleeved on, end rail is sleeved on the bottom and installs on the supporting plane, last rail bottom is provided with rail tooth bar pulley yoke, and rail top, the end is provided with end rail tooth bar pulley yoke, adopts gear drive between last rail tooth bar pulley yoke and the end rail tooth bar pulley yoke; At last rail end restorer is set, the rail end is provided with damper the end of at.
In the utility model, end rail is connected with support, and support is at least one, two of operated by rotary motion, and support generally adopts shapes such as " L " shape support or plate shaped support.In the utility model, the cross section of middle rail can adopt shapes such as " Contraband " shape, " worker " shape; Last rail and middle rail are nested structure, and middle rail and end rail are nested structure, promptly go up rail and have the structure that supporting plane is installed on rail top in the bag embedding, and end rail has the structure that supporting plane is installed in the rail bottom in the bag embedding.In the utility model, around the tooth bar pulley yoke pulley can be set.Slide block moves around in the damping frame guide groove.In the utility model, restorer can use stretcher spring etc., stretcher spring one end is fixed on slide block button bit place (thereby go up the rail pull time damping collude the contraction that drives the slide block movement control spring), and the other end is fixed on damping frame button bit place (it is motionless that damping frame is fixed on end rail).In the utility model, damper can adopt this area damper commonly used, as the hydraulic oil cylinder type damper etc.In the utility model, in maximum unzipped positions position limiting structure is set between last rail and the middle rail, in maximum unzipped positions position limiting structure is set between end rail and the middle rail, above-mentioned position limiting structure can be projection and a groove structure corresponding between the contact-making surface.In the utility model, the length of three joint slide rails (going up rail, middle rail and end rail) can equate or be unequal that it is relative with end rail longer in general to can be designed as rail, and middle rail is short relatively, length as middle rail can be to go up 50%～100% of rail length, last rail and end rail equal in length.
The utility model adopts three joint slide rails, can realize that the integral body of drawer is all pulled out; By tooth bar pulley yoke and pulley are set between slide rail, can make the slide rail operation freely, frictional force is little, has eliminated sliding friction generation noise between the slide rail.By position limiting structure and restorer are set, slide rail is pulled out after, be fixed on suitable location, after finishing using, when breaking away from position limiting structure, the effect by restorer can automatically revert to the origin-location.By damper is set, in the time of can guaranteeing that slide rail resets steadily, no hard collision, do not produce noise, increase the service life.The utility model three joint slide rails can be widely used in fields such as high-grade family kitchen cabinet, furniture, office accommodation and drawer type household appliances.
