Description

The synchronous double buffering drawer guideway of three joints

Technical field

The utility model belongs to furniture part, especially a kind of three joint drawer guideways that have smooth feel when dragging drawer.

Background technology

Common drawer guideway divides rail, middle rail, lower rail or movable rail, mid-rail, retaining rail three joints, between movable rail and middle rail, middle rail and the retaining rail roller or ball are arranged, roller and ball are retrained by retainer, owing to be rolling friction between the guide rail when drawer moves, so more laborsaving.In the use of three joint guide rails, it is found that because precision and the assembling means of part 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, affect feel.Name is called " integrated drawer guide rail " patent application (CN101623150A), it " between lower rail (1) and the middle rail (2) retainer (9) is arranged, between middle rail (2) and the upper rail (3) retainer (9) is arranged; Cylinder row (10) is arranged on the retainer (9), and cylinder row (10) is formed along arranged in a straight line by the identical cylinder in a plurality of intervals, and flywheel (11) is arranged on the described middle rail (2); Cylinder row (10) on the retainer (9) between lower rail (1) and the middle rail (2) with the cylinder on the retainer (9) between middle rail (2) and the upper rail (3) arrange (10) parallel relative and all contact with flywheel (11)." so make two covers, the three joint guide rails that are installed in the drawer both sides synchronously flexible when motion, the feel when having improved the push-and-pull drawer.Yet when drawer is outwards hauled out when 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, and bump also can cause play before and after the drawer.

Summary of the invention

The purpose of this utility model provides 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 retaining rail, mid-rail, movable rail, panel connector and buffer; The cross section of mid-rail roughly is " Contraband " shape, and the cross section of retaining rail and movable rail roughly is " ┌ ┐ " shape, and retaining rail and movable rail respectively are installed in 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 has a gear to be installed on the 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 movable rail when fully slippage is stretched out on the mid-rail, the first stopping projection contacts with the first elastomer on the roller rolling retainer between movable rail and the mid-rail; When mid-rail when fully slippage is stretched out on the retaining rail, the second stopping projection contacts with the first elastomer on the roller rolling retainer between mid-rail and the retaining rail; Front end in retaining rail is shaped with the first locking plate, is shaped with the second locking plate in the rear end of movable rail; When mid-rail when fully slippage is stretched out on the retaining rail, the first locking plate contacts with the second elastomer on the roller rolling retainer between mid-rail and the retaining rail; When movable rail when fully slippage is stretched out on the mid-rail, the second locking plate contacts with the second elastomer on the roller rolling retainer between movable rail and the mid-rail.

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