Description

The synchronous double buffering drawer guideway of three joints

Technical field

The invention belongs to furniture part, especially a kind of three joint drawer guideways that there is smooth feel while dragging drawer.

Background technology

Common drawer guideway divides rail, middle rail, lower rail or active rail, mid-rail, fixed track three joints, roller or ball are arranged between active rail and mid-rail, mid-rail and fixed track, roller and ball are retrained by retainer, while moving due to drawer, between guide rail, be rolling friction, so more laborsaving.In the use of three joint guide rails, it is found that precision and assembling means due to part there are differences, cause the force of rolling friction between rail and rail inhomogeneous, between slide rail, the order of folding is uncertain, cause the drawer left and right sides to drag resistance inconsistent, affect feel.Name is called " integrated drawer guide rail " patent application (CN101623150A), it " between lower rail (1) and middle rail (2), retainer (9) is arranged, between middle rail (2) and upper rail (3), retainer (9) is arranged; Cylinder row (10) is arranged on retainer (9), and by a plurality of intervals, identical cylinder forms along arranged in a straight line cylinder row (10), and flywheel (11) is arranged on described middle rail (2); Cylinder row (10) on retainer (9) between lower rail (1) and middle rail (2) with the cylinder on the retainer (9) between middle rail (2) and upper rail (3) arrange (10) parallel relative and all with flywheel (11), contact." so make the two cover three joint guide rails that are arranged on the drawer both sides synchronously stretch when motion, the feel while having improved the push-and-pull drawer.Yet when drawer is outwards hauled out while being at the end hastily, the locking plate that the rear end that the front end of retainer tends to knock suddenly the locking plate that is arranged on the guide rail front end or retainer is arranged on the guide rail rear end knocks and sends sound, clashes into and also can cause play before and after drawer.

Summary of the invention

The purpose of this invention is to provide smooth, the steady noiseless synchronous double buffering drawer guideway of three joints of a kind of folding.

The synchronous double buffering drawer guideway of three joints comprises fixed track, mid-rail, active rail, panel connector and buffer; The cross section of mid-rail roughly is " Contraband " shape, and the cross section of fixed track and active rail roughly is " ┌ ┐ " shape, and fixed track and active rail respectively are arranged on below and the top of mid-rail by a roller rolling retainer; It is characterized in that roller rolling retainer presses close to the part of mid-rail vertical plane and be shaped with the tooth bar of arranging along the roller rolling retainer moving direction; The end at the tooth bar of an end of roller rolling retainer is shaped with the first elastomer, and the partial fixing of pressing close to the mid-rail transverse plane at the roller rolling retainer other end has the second elastomer; The vertical plane central authorities sprocket drive spindle of mid-rail, have a gear to be arranged on gear shaft; Tooth bar on two roller rolling retainers relatively parallel and also all with Gear Contact; The front end of the vertical plane of mid-rail is shaped with first stopping projection, and the rear end of the vertical plane of mid-rail is shaped with second stopping projection, and the first stopping projection and the second stopping projection lay respectively on the mobile route of two roller rolling retainers; When active rail, mid-rail, fully slippage is stretched out, the first stopping projection contacts with the first elastomer on roller rolling retainer between active rail and mid-rail; When mid-rail, fixed track, fully slippage is stretched out, the second stopping projection contacts with the first elastomer on roller rolling retainer between mid-rail and fixed track; Front end in fixed track is shaped with the first locking plate, in the rear end of active rail, is shaped with the second locking plate; When mid-rail, fixed track, fully slippage is stretched out, the first locking plate contacts with the second elastomer on roller rolling retainer between mid-rail and fixed track; When active rail, mid-rail, fully slippage is stretched out, the second locking plate contacts with the second elastomer on roller rolling retainer between active rail and mid-rail.

The invention provides the Chi Lun ∕ rack structure that makes three joint guide rail synchronous on-offs, guaranteed that the two cover guide rails that are arranged on the drawer both sides synchronously stretch; And be provided with respectively the first elastomer and the second elastomer at two of roller rolling retainer, when guide rail all stretches, two roller rolling retainers go contact to be positioned at the first/the second stopping projection on mid-rail, with the second elastomer, to go contact to be positioned at the first locking plate on fixed track or to be positioned at the second locking plate on the slip rail with the first elastomer, the first elastomer and the second elastomer produce elastic deformation is cushioned the collision between three joint rails and roller rolling retainer, the feel while greatly having improved the push-and-pull drawer; The collision that the present invention has produced while having reduced braking shakes and has reduced noise, and simple in structure, effect is remarkable, and suitable being arranged on all furniture used.
