Description
Technical field
The utility model relates to furniture hardware fitting, is specifically related to be applied to the drawer guideway on furniture and industrial goods.
Background technology
Ball guide divides light-duty ball guide and heavy ball guide; Be the track sliding thereon for moving component, be generally flute profile, moving component end is fixed with roller, ball or slide block, and slide block, roller or ball are sticked in orbital groove, can in groove, slide, and moving component is moved on slide rail.Ball guide is exactly to adopt the slide rail of high-precision steel ball as ball, the outer bar of general slide rail is embedded with a sequin, the use of both sides steel ball fixes, moving component is placed on sequin, make moving component to front slide by the rolling of steel ball, be used for cabinet, wardrobe drawer and tool box, Tool Cabinet, fire fighting truck etc.Easily fill readily removable, without instrument, level and smooth noiseless is its main feature.Divide from the joint number of slide rail, can be divided into three joints and two joint slide rails; Divide from the tensile elongation of slide rail, can be divided into entirely drawingly, 3/4 is drawing, and non-stretchable formula.Material mostly is cold-rolled steel, has roller cold roll forming, then punching press plating is assembled.
The general steel ball hiding conductive of existing ball guide rail steel pearl position distribution has two kinds: Yi Zhongshi, and outer rail is respectively connected with 3 row steel balls with interior rail with middle rail, middle rail, and 6 steel balls form day font.This steel ball position distribution manufacture difficulty is large, and effect is bad, is a day font because steel ball distributes, and makes guide rail and very easily waves.Another kind is, outer rail is connected with 3 row steel balls with middle rail, forms a little triangle, and middle rail is connected with 4 row steel balls with interior rail, forms a parallelogram, due to outer rail and middle rail composition triangle too little, make very easily and wave.The quadrangle of middle rail and interior rail composition, an approximate circle, also very easily waves effect extreme difference.
Utility model content
The utility model provides the full exhibition of seven pearls three joints hidden steel ball drawer guideway, solved in prior art, exist the guide rail of ball guide easily to wave, the problem such as assembly process.
For addressing the above problem, the utility model adopts following technical scheme: the full exhibition of seven pearl three joints hidden steel ball drawer guideway, it is characterized in that, formed by outer rail (1), middle rail (2) and interior rail (3), outer rail (1), middle rail (2) and interior rail (3) cross section are flute profile, two side height of interior rail (3) are not etc., middle rail (2) and outer rail (1) are all sleeved on the short limit of interior rail (3), and middle rail (2) is positioned between outer rail (1) and rail (3); Between outer rail (1) and middle rail (2), be provided with outer rail pearl frame (5), four lines steel ball (4) is installed on outer rail pearl frame (5); Between middle rail (2) and interior rail (3), be provided with interior rail pearl frame (8), three row steel balls (4) are installed on interior rail pearl frame (8).
Advantage of the present utility model: 1, this practicality focus on the position that steel ball is put: between interior rail and middle rail, the position of three row steel balls is: the right and left equity, form an isosceles acute triangle, stablizing when triangle is conducive to interior rail and the slip of middle rail, be not easy to vacillate now to the left, now to the right, can bear heavier gravity and indeformable; The position of 4 row steel balls between middle rail and outer rail, there are two row steel balls directly over middle rail, other two row are placed in middle rail below the right and left, and middle rail top two row and below two row steel bead grooves form a this structure of antiparallelogram and are conducive to middle rail and the stability of outer rail in the time of operation, works very well.Can bear heavier gravity and indeformable; 2, the utility model has improved the stability of ball guide, draws continually drawer over to one's side, and drawer can not wave and bump; Make ball guide buffering effect better, pull out energetically or push back drawer, withdrawal that can be slowly gentle; Increased the smoothness of ball guide, use can be slim and graceful when drawer pull, there is no abnormal sound; 3, the utility model production fit on is better quick, has reduced assembly process, in the time of assembling guide rail, fixes fast in its appearance.

Detailed description of the invention
With best embodiment, the utility model is described in detail below
.
As Figure 1-4, the full exhibition of seven pearl three joints hidden steel ball drawer guideway, it is characterized in that, formed by outer rail (1), middle rail (2) and interior rail (3), outer rail (1), middle rail (2) and interior rail (3) cross section are flute profile, two side height of interior rail (3) are not etc., middle rail (2) and outer rail (1) are all sleeved on the short limit of interior rail (3), and middle rail (2) is positioned between outer rail (1) and rail (3); Between outer rail (1) and middle rail (2), be provided with outer rail pearl frame (5), four lines steel ball (4) is installed on outer rail pearl frame (5); Between middle rail (2) and interior rail (3), be provided with interior rail pearl frame (8), three row steel balls (4) are installed on interior rail pearl frame (8).
Interior rail pearl frame (8) arranges (9) by two inner integuments and an interior link (10) forms; Two inner integument rows (9) are connected side by side with the front and back end of interior link (10); Three row steel balls (4) are nested in interior rail pearl frame (8), and three row steel ball (4) cross sections after nested become isosceles acute triangles to arrange.
