Description

Three-section synchronous drawer guide rail
Technical field
The invention belongs to field of furniture, especially a kind of three joint drawer guideways that have when dragging drawer along sliding feel.
Background technology
The common movable rail of drawer guideway branch, middle rail, retaining rail three joints all have roller or ball between movable rail and middle rail, middle rail and the retaining rail, and roller and ball are retrained by retainer, are rolling friction between the guide rail when moving owing to drawer, so more laborsaving.In the use of three joint guide rails, part precision and assembling means it is found that owing to there are differences, cause the force of rolling friction between rail and the rail inhomogeneous, the order of folding is uncertain between the slide rail, cause the drawer left and right sides to drag resistance inconsistent, influence feel, this point is need be improved.
Summary of the invention
The purpose of this invention is to provide a kind of folding more along sliding three-section synchronous drawer guide rail.
Three-section synchronous drawer guide rail comprises retaining rail, middle rail, movable rail and buffer; Retaining rail is fixed on drawer cupboard inwall, between retaining rail and the middle rail first retainer is arranged, and between middle rail and the movable rail second retainer is arranged; First tooth bar is arranged on first retainer, and movable rail has second tooth bar, on the middle rail bevel gear is arranged; First tooth bar is relatively parallel and all contact with bevel gear with second tooth bar.
As a further improvement on the present invention, on the bottom surface of middle rail angular wheel shaft is arranged, bevel gear is installed on the angular wheel shaft.
The invention provides the bevel gear/rack structure that makes three joint guide rail synchronous on-offs, guaranteed that two covers, the three joint guide rails that are installed in the drawer both sides synchronously stretch the feel when having improved the push-and-pull drawer greatly, compact conformation of the present invention when motion, easy for installation, suitable being installed on all furniture used.

The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
Feature technology of the present invention for convenience of description, Fig. 1 to Fig. 3 all canting product put posture, D position pointed is the bottom of product among Fig. 1, in the actual use of product, this position is down.
Referring to Fig. 1 to Fig. 6, embodiment 1 has retaining rail 1, middle rail 2, movable rail 3, first retainer 4 and second retainer 5 and the buffer 8 etc. in the traditional product.Retaining rail 1, middle rail 2, movable rail 3 all are metal plate punching spares; First retainer 4 and second retainer 5 are made of plastics, first retainer 4 is between retaining rail 1 and the middle rail 2, second retainer 5 is between middle rail 2 and the movable rail 3, roller 21 in each retainer contacts with movable rail 3 with middle rail 2 or middle rail 2 with retaining rail 1 simultaneously, retaining rail, middle rail, movable rail is rolls to cooperate; Edge die casting at first retainer 4 goes out first tooth bar 6; On the bending side of movable rail 3 bottoms, be fixed with one with the same plastic second tooth bar, 7 (see figure 6)s of first tooth bar 6; Bending side middle part riveted joint in middle rail 2 bottoms has an angular wheel shaft vertical with bending side 10, is set with plastic bevel gear 9 (see figure 5)s on the angular wheel shaft 10, and bevel gear 9 can freely rotate on angular wheel shaft 10; First tooth bar 6 on first retainer 4 is relatively parallel and all contact with bevel gear 9 with second tooth bar 7 on the movable rail 3, and the cone angle of bevel gear 9 is about 90 °, and correspondingly, the flank of tooth inclination angle of first tooth bar 6 and second tooth bar 7 is about 45 °.Two at middle rail 2 is shaped on the spacing block set (not shown) respectively, at two of retaining rail 1 and movable rail 3 the spacing block set (not shown) is arranged also, and they make first retainer 4 and second retainer 5 can be from retaining rail 1 or rail 2 or from movable rail 3 slippages therefrom.
Referring to Fig. 7 to Fig. 9, buffer comprises that damper seat 11, damping tube 12, damper draw pin 13, screwed pipe extension spring 14, damper pulling block 15, damper slide block 16 and dial pin 17.
There is piston damping tube 12 the insides, piston draws pin 13 to be connected with damper pulling block 15 by damper, damper pulling block 15 is hinged with damper slide block 16, makes damper slide block 16 move along slideway 19 in the slideway 19 of the projection 18 embedding damper seats 11 on the damper slide block 16; Screwed pipe extension spring 14 is installed between damper seat 11 afterbodys and the damper pulling block 15, and damper seat 11 is fixed on the inwall of retaining rail by card base 20; Dial pin 17 and be welded on the movable rail, dial pin 17 and dynamically be connected with damper slide block 16.When drawer was outwards pulled out from the lining, group pin 17 fastened damper slide block 16 and moves to right together, and screwed pipe extension spring 14 is by energy storage; When drawer is closed from outside to inside, pulling force is provided and drawer is steadily voicelessly clapped by screwed pipe extension spring 14 and close.
Referring to Figure 10 and Figure 11, under the common restraining function of first tooth bar 6 and the bevel gear 9 and second tooth bar 7, first retainer 4 and movable rail 3 are that uniform velocity is carried out in the other direction with respect to the motion of middle rail 2, thereupon retaining rail 1 and movable rail 3 with respect to the motion of middle rail 2 basically also in the other direction uniform velocity carry out, therefore, two covers, the three joint guide rails that are installed in the drawer both sides also are synchronous when motion, make the frictional force basically identical of drawer left and right sides in the process that opens and closes, improved feel greatly.
Referring to Figure 12, embodiment 2 is that with the difference of embodiment 1 overbending direction of retaining rail 1 is different, and the cross sectional shape of first retainer 4, middle rail 2, second retainer 5 and movable rail 3 all is respectively the mirror image among the embodiment 1; Thereupon, bevel gear 9, angular wheel shaft 10, first tooth bar 6, second tooth bar 7 all move into the inboard of retaining rail 1; Bevel gear 9, angular wheel shaft 10, first tooth bar 6, second tooth bar 7 rail 1 that all is fixed is surrounded and is protected.Though the shape of each parts is different with embodiment's 1, their function is identical.
