Abstract

The invention relates to a rectangular slideway, which belongs to a hardware product and comprises a slideway A and a slideway B, wherein, the slideway B is surrounded by the slideway A, the section of the slideway A takes a shape of a rectangular, one edge of the rectangular is provided with a first opening, the section of the slideway B takes a T shape, and a T-shaped longitudinal beam stretches into the first opening of the slideway A; the four inner angles of the slideway A are provided with an arc channel, a ball is arranged between the slideway B and the four inner angles of the slideway A, wherein, on the two end parts of the beam of the T-shaped section of the slideway B, the arc channel is contacted with the ball, and on the waists of the two sides of the T-shaped section of the slideway B, the arc channel is contacted with the ball. Compared with a traditional slideway, the rectangular slideway of the invention uses four balls as a support between the two layers of slideways, which makes the slideway be more firm and reliable; and moreover, the ball rolls along the arc channel, which has precise cooperation, small gap and good hand feeling, and can be suitable for being installed and used on all furniture.

Description

Rectangular guideway

Technical field

The present invention relates to hardware, particularly a kind of furniture guide rail.

Background technology

The general line slideway of installing in the drawer of furniture belongs to two-wheel or two pearl structure, though structure is simpler, poor stability rocks during the drawer motion, and load capacity is little, is not suitable for being necessary to improve on the high-grade furniture.

Summary of the invention

The object of the present invention is to provide a kind of compact conformation, smooth operation along the rectangular guideway sliding, that load capacity is big.

The present invention includes first rail and second rail, the first rail surrounds the second rail, it is characterized in that first rail cross section is rectangular, on a limit of rectangle opening is arranged, and the cross section of second rail roughly is the opening that "T"-shaped, "T"-shaped longeron stretches into the first rail; 4 interior angles of first rail have the arc ditch, between 4 interior angles of first rail and the second rail ball are arranged, and wherein, the crossbeam both ends in " T " cross section of second rail have the arc ditch to contact with ball, and the both sides waist in " T " cross section of second rail has the arc ditch to contact with ball.

As a combination of the present invention, described second rail can be double T shape conjoined structure, and the first rail has two, and each first rail surrounds the shape of the T up and down track of second rail respectively, between 4 interior angles of each first rail and the second rail ball is arranged.

As another combination of the present invention, fill up the rail and third rail in addition in the periphery of first rail, the pad rail is fixed in first rail and opening relative edge's the outside, the cross section of third rail is rectangular, third rail surrounds first rail and pad rail, third rail has second opening on the limit corresponding with the opening of first rail, there is the arc ditch interior angle of third rail and two inboards; There is the arc ditch in two outsides of first rail, between the third rail inwall and the pad rail ball are arranged, and between the third rail inwall and the first rail wall ball are arranged, and between the third rail inwall and the pad rail change gear are arranged.

Compared with traditional guide rail, the present invention has 4 row balls (or change gear) as the support between the two-layer track along the length direction of track, makes guide rail firm reliable; And ball rolls along the arc ditch, cooperates accurately, and the gap is little, and feel is fine, and suitable being installed on all furniture used.

Description of drawings

Further specify the present invention below in conjunction with drawings and Examples.

Fig. 1 is the cutaway view of embodiment 1;

Fig. 2 is the cutaway view of embodiment 2;

Fig. 3 is the cutaway view of embodiment 3.

The specific embodiment

Referring to Fig. 1, among the embodiment 1, first rail 1 is formed by the steel plate bending, its cross section is roughly rectangular, on limit, bottom of rectangle opening 2 is arranged, second rail 3 also is to form with the steel plate bending, and it is "T"-shaped that its cross section roughly is, "T"-shaped longeron 4 extends into the opening 2 of first rail 1, and longeron 4 can be used for being connected with the drawer cupboard; 4 interior angles of first rail 1 have arc ditch 5, between 4 interior angles of first rail 1 and the second rail 3 ball 6 is arranged, wherein, the crossbeam both ends in " T " cross section of second rail 3 have arc ditch 5 to contact with two balls 6, and the both sides waist in " T " cross section of second rail 3 has arc ditch 5 to contact with two balls 6.Because all there is the ball support in 4 corners and does not have visible gap between first rail and the second rail, make that the cooperation of first rail and second rail is very accurate, move very steady.

Referring to Fig. 2, on shape, the second rail of embodiment 2 is double T shape conjoined structure, and the second rail is to be formed by same steel plate bending; It has two first rails, and two first rails surround the shape of the T up and down track of second rail respectively; On same cross section, have 8 balls between 4 interior angles of each first rail and the second rail.Embodiment 2 can make three joint guide rails, and wherein the second rail is free rail, two first rails can be separately fixed on the drawer cupboard and drawer on.

Referring to Fig. 3, as another distortion combination of embodiment 1, the top of first rail 1 also has a pad rail 7, and pad rail 7 is welded on the outer surface on that relative limit of first rail 1 and opening 2, the end top is shaped on arc ditch 5 about pad rail 7, and the end below is shaped on flat face 8 about pad rail 7; The periphery of first rail 1 also has the cross section of third rail, 9, the third rails 9 also roughly rectangular, and third rail 9 surrounds first rails 1 and pad rail 7, the third rails 9 has second opening 10 on the limit corresponding with the opening 2 of first rail 1; There is arc ditch 59 liang of inboards of third rail, and corresponding with it, two outsides of first rail 1 also have arc ditch 5, the third rails 9 inwalls that ball 6 and change gear 11 are housed; On same cross section, there are two balls 6 to contact simultaneously with the arc ditch 5 of third rail 9 and the arc ditch 5 of pad rail 7, there are two balls 6 to contact simultaneously, have two change gears 11 to contact simultaneously with the inboard on that limit that second opening 10 is arranged of third rail 9 and the flat face 8 of pad rail 7 with the arc ditch 5 of third rail, 9 inwall arc ditches 5 and first rail 1 sidewall.

In each embodiment, all balls and change gear all rely on ball retainer or change gear retainer (not shown) to constrain on the tram.
