Description

Drawer guideway

Technical field

The utility model belongs to a kind of drawer annex of furniture.

Background technology

Existing drawer guideway, dividing has left drawer guideway and right drawer guideway, and it comprises outer rail, middle rail and interior rail, and the outer surface of interior rail and outer rail all has two tabs, the projected direction of an interior rail tab is identical with the pull-out direction of drawer, and rail tab is outstanding straight up in another; The projected direction of an outer rail tab is opposite with the pull-out direction of drawer, and another outer rail tab is outstanding straight down.Interior rail tab blocks the drawer side installing rack, and the outer rail tab blocks drawer cupboard installing rack.This drawer guideway has the advantage practical, that framework is firm, quick for installation.But because the branch of this drawer guideway about having, both can not be general, must make respectively, has shortcomings such as producing complicated, assembling inconvenience.

Summary of the invention

The purpose of this utility model is to provide a kind of is convenient to install, about be suitable for the drawer guideway that framework is firm.

The utility model comprises outer rail, middle rail and interior rail, and first ball retainer of gathering sill and band ball is arranged in the outer rail, and second ball retainer of gathering sill and band ball is arranged in the middle rail; Interior rail outer surface has two tabs, and the projected direction of the tab of interior rail outer surface is identical with the pull-out direction of drawer; The outer rail outer surface has two tabs, and the projected direction of the tab of outer rail outer surface is opposite with the pull-out direction of drawer; Outer rail outer surface and interior rail outer surface have the non-return piece.

As further improvement of the utility model, the tab cross section is " factory " font.

As further improvement of the utility model, non-return piece cross section is the right angle trigonometry type.

As further improvement of the utility model, interior rail outer surface and outer rail outer surface have leaf spring.

The utility model can about be suitable for, and framework is firm, is applicable to any drawer.

The specific embodiment

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, present embodiment has outer rail 1, middle rail 2 and interior rail 3.Be shaped in the outer rail 1 in gathering sill 4 and first ball retainer, 5, the first ball retainers 5 ball 7 is arranged; Middle rail 2 is shaped on the gathering sill 4 that matches with outer rail 1 outward and is sleeved in the outer rail 1, and moves along outer rail 1 in the distance that can limit at the stopping means of middle rail 2; In be shaped on gathering sill 4 in the rail 2, interior rail 3 is outer to be equipped with in the gathering sill 4 that matches with middle rail 2 and second ball retainer, 6, the second ball retainers 6 ball 7; Interior rail 3 is sleeved in the middle rail 2, and moves rail 2 and interior rail 34 link stoppers of deviating from 11 from gathering sill during the gathering sill 4 of outer rail 1 is provided with and can prevents along middle rail 2 in the distance that can limit at the stopping means of interior rail 3.Interior rail 3 outer surfaces have two tabs 9, and the projected direction of the tab 9 on the interior rail 3 is identical with the drawer pull-out direction, and outer rail 1 outer surface also has two tabs 9, and the projected direction of the tab 9 on the outer rail 1 is opposite with the drawer pull-out direction.The cross section of tab 9 is " factory " font.By the tab 9 of outer surface near front end of outer rail 1, a non-return piece 8 is arranged, by the tab 9 of interior rail 3 outer surfaces, a non-return piece 8 is arranged also near the rear end.The cross section of these two non-return pieces 8 by right angled triangle and its hypotenuse towards its close tab 9.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the other punching out of outer rail 1 surperficial tab of the present utility model goes out a leaf spring 10, and the leaf spring 10 of outer rail 1 outer surface is outstanding to the surface of outer rail 1.Go out a leaf spring 10 at interior rail 3 outer surfaces in the tab 9 other punching out near front end, the surface of the leaf spring 10 inside rails 3 of interior rail 3 outer surfaces is outstanding.

Referring to Fig. 6, Fig. 7, the utility model needs to be connected with installing rack when mounted, parallel drawer side and the drawer cupboard sidewall of being packed in of installing rack.The installing rack of drawer side is used for being connected with interior rail 3, the installing rack of drawer cupboard sidewall is used for being connected with outer rail 1, the cross section of installing rack roughly is ", have two spikes 12 and raised face 13, spike 12 usefulness screws are fixed, square hole 14 is arranged in the raised face 13, and raised face 13 height are corresponding with the projecting height of tab 9.During installation, two tabs 9 on interior rail 3 and outer rail 1 surface are passed simultaneously the square hole 14 of two installing racks, and rail 3 and outer rail 1 make tab 9 snap in the raised face 13 of installing rack in promoting, when below non-return piece 8 slides into square hole 14, non-return piece 8 just blocks the another side of square hole 14, thereby guide rail is locked on the installing rack.In order to make guide rail loosening, rail 3 outer surfaces and outer rail 1 outer surface are equipped with leaf spring 10 in the drawer, and when tab 9 snaps in the installing rack raised face 13, leaf spring 10 is exerted pressure to installing rack raised face 13 all the time.Eliminate the gap between guide rail and the installing rack.When needs unload lower guideway, need lever up installing rack and make it cross non-return piece 8, remove the locking of 8 pairs of guide rails of non-return piece, make guide rail loosening, can easily unload.

In another embodiment when drawer cupboard side plate and drawer side all be under the situation about making of steel plate, can on drawer cupboard side plate and drawer side, directly leave square hole 14, like this, just corresponding two square holes 14 that snap on the drawer cupboard side plate of two tabs 9 on the outer rail 1, just corresponding two square holes 14 that snap on the drawer side of two tabs 9 on the interior rail 3.
