Description

Improved detachable drawer slide

The utility model relates to a kind of detachable drawer slide, especially relates to the detachable drawer slide that is applied in the furniture.

As be applied in the drawer of all kinds of furniture or the keyboard activity carriage in the computer desk etc., all be to utilize in drawer two sides and the furniture to install one group of drawer sliding rail respectively between the corresponding sidewall in relative bracket system place between the corresponding sidewall in drawer place or the carriage both sides and computer desk, utilize the principle that is slidingly matched of the relative sliding sash of ball in the slide rail, make drawer or carriage possess the function of easy extraction or pushed home.

The design of present known detachable drawer slide, as United States Patent (USP) 5,466, No. 060 " drawer sliding rail " (DRAWER SLIDE WITH ACCESS HOLES) or United States Patent (USP) the 5th, 722, No. 750 " sliding rail structure of drawer " patents such as (STRUCTURE OF SLIDING TRACKFOR DRAWERS) discloses, wherein drawer sliding rail shown in them all has one and can be fixed in the furniture the fixedly sliding sash of two side, drawer place relatively, be provided with a ball slide plate that can slide along sliding sash in the sliding sash, the sliding sash front and back end is provided with a block and a fastener respectively, to limit the scope that the ball slide plate slides, respectively establish rail in the drawer two side again, should interior rail correspondence be arranged in the ball slide plate, be resisted against on the ball that ball slide plate upper and lower side is arranged in a linear with its two side ends, make in rail relatively the ball slide plate slide, again when avoiding drawer to extract out, whole drawer is drawn out, relative ball slide plate place device one elastic braking plate on interior rail, use the fastener that utilizes the sliding sash front end supporting of brake(-holder) block ended restriction, preventing that drawer is whole is drawn out, when drawer is desired to extract out in furniture, then push elastic braking plate it is broken away from after supporting of fastener end state, drawer can be extracted out with hand.

Though the design of two existing drawer sliding rails of above-mentioned announcement can provide a kind of auxiliary drawer push-and-pull rail structure smoothly, and some shortcomings are still arranged in the structure of this two existing drawer sliding rail, so that in that use in the operation can't best practical function, wherein:

Above-mentioned United States Patent (USP) 5,466, No. 060 drawer sliding rail, because of its brake(-holder) block is that an end is fixed on the interior rail, end is the perk shape in addition, so the perk end of brake(-holder) block is pulled out at drawer, in the push-on process, can rub mutually with the slide plate side of tool ball, the drawer push-and-pull be formed resistance, and influence the smooth and easy of drawer push-and-pull, again, its brake(-holder) block comparatively smooth and press close in the trackside face so that people to push the stroke of brake(-holder) block shorter, old friends' desire is pulled out whole drawer, needing to compress brake(-holder) block disengaging fastener with bigger strength can reach, and the problem of the effort disassembled is arranged.

Above-mentioned United States Patent (USP) the 5th, 722, drawer sliding rail in No. 750 " sliding rail structure of drawer ", though its brake(-holder) block two ends are fixed on interior trackside face, can avoid aforementioned problem because of brake(-holder) block perk and slide plate friction, but its brake(-holder) block is to take the not design of equal thickness, wherein the people place of pushing is positioned at the thicker part of thickness brake(-holder) block, two ends are fixed fully in addition, make its brake(-holder) block end not have extensile space fully, so must impose bigger strength, the brake(-holder) block distortion is broken away from by the clip shape, so still have the problem of disassembling effort.

In order to overcome the deficiencies in the prior art, that the purpose of this utility model is to provide is more laborsaving in a kind of use operation, improved detachable drawer slide easily.

In order to achieve the above object, the sliding rail structure of drawer design that the utility model proposed, be in sliding sash, to be provided with a ball slide plate that can slide along sliding sash, the sliding sash front and back end is provided with block and fastener respectively, the interior rail that installing one can be slided along slide plate in slide plate, interior trackside face device one can be fastener to ending spacing elastic braking plate, brake(-holder) block is with its fork, the place was colluded in the fixed hook and the location of rail in the portion of plugging was positioned at, wherein, brake(-holder) block plugs the portion both sides and extends and can supporting of corresponding butt fastener stopper section end protuberance, and plug the portion side and form a prominent button, the spacing that provides greater than brake(-holder) block thickness is provided in the location of interior rail, and the relative positioning place of colluding forms one the brake(-holder) block button hole that prominent button activity is inserted is provided, but the button hole dual-side forms contact brake(-holder) block teat, and form the lever state, make people can push brake(-holder) block and fastener effortlessly and break away to ending spacing state, and then a kind of laborsaving easy-operating detachable drawer slide structure is provided.

The beneficial effects of the utility model are: the utility model removes and the brake(-holder) block two ends to be colluded by the fixed hook of interior rail and location located, avoid brake(-holder) block when the drawer pull and the slide plate friction, prior, the location of rail is colluded and is provided brake(-holder) block to plug the movable extending space of portion in the utility model utilization, and interior rail relative positioning colludes the side teat contact portion that plugs and forms the lever kenel, make the people when disassembling, can labour-saving mode operate, and reach effect easy to use.

Below in conjunction with accompanying drawing the utility model is elaborated:
