Description

Push-press type slide rail automatic switch structure

Technical field

The utility model refers to a kind of push-press type slide rail automatic switch, with its structurally associated.

Background technology

Desk, cabinet or the like furniture mostly makes things convenient for the keying of drawer by the linear slide rail that is a group in twos at present, reaches to come into plain view and the effect of ruly storage thing.This kind structure configuration is tried hard to recommend moving this drawer beyond mainly being and is closed, yet the effect that block is not arranged when closing, thereby in a single day the loaded with articles ornaments that run into drawer are bad, or be subjected to the influence of topography, drawer after then closing goes out slippage once again, and even the phenomenon of deviating to drop, cause the disappearance of damaging article in the drawer, therefore just have a kind ofly can reach the technology of opening drawer and produce by pushing for the second time, just its concrete structure shown in No. 85219586 patent case of TaiWan, China application as.

Case mainly is to set firmly a rail box at the furniture internal face before this patent, and the drawer inner face then sets firmly a handle, after pushing drawer for the first time, can close by operating drawer, and after pushing drawer once more, then can open automatically.This kind technology must make furniture, drawer that linear slide rail is installed in advance, continue it, just rail box, handle are mounted to furniture, drawer precalculated position respectively, so its assembling is not more had efficient far beyond tradition, and its rail box, handle are installed in the confined space of furniture, drawer, except that suitable trouble, and limited the usage space of drawer relatively.

Because the disappearance of above-mentioned patent case, this creator actively makes great efforts research, through test of many times and improvement, develops finally and the utility model.

The utility model content

The purpose of this utility model is to provide a kind of push-press type slide rail automatic switch structure, by the control mode of secondary pushing, can reach the function of use of automatic open close drawer.

For reaching above-mentioned purpose, the technical solution of the utility model is: a kind of push-press type slide rail automatic switch structure includes: a linear slide rail has and can slide retaining rail and the movable rail that closes relatively; One slide block, it is provided with preceding pod, back pod at interval; One can be along the preceding tightening latch of slippage about the preceding pod; One can be along the back tightening latch of slippage about the pod of back; An and lock, it is provided with the translot, that can guide preceding tightening latch and back tightening latch can be for the dashpot of preceding tightening latch in response to slippage about the preceding pod, and between lock and slide block, spring is installed, at this spring tension hour, should be positioned the dashpot place by preceding tightening latch, then tightening latch then is positioned in the translot; This lock is equipped with in addition fork pockets, fork pockets down in the translot rear end, and between this upper and lower fork pockets vertically tiltedly shape be communicated with a clamping groove, when tightening latch moved behind translot before movable rail promotion, back tightening latch can enter along last fork pockets in the holding section of clamping groove and locate; Before promoting backward once more during tightening latch, thereafter tightening latch can be along fork pockets down and involution in translot, as for preceding tightening latch then can involution in the corresponding dashpot of translot.

This lock be provided with a bottom be communicated in the translot front end and with the corresponding dashpot of preceding pod, make this dashpot form for preceding tightening latch in response to the preceding pod cushion space of slippage up and down.

This lock is provided with second dashpot, and with a connecting groove conducting translot, second dashpot, and between translot, second dashpot, connecting groove, be formed with a card article, described connecting groove, second dashpot run through lock, then be formed with the portion of emptying as for lock at translot, card article joining place, make this second dashpot form for card article, preceding tightening latch in response to the preceding pod cushion space of slippage up and down.

This lock has opposing backside surface, front, this back side can be mounted on the retaining rail end edge of linear slide rail, the positive slide block cunning that supplies is closed, described movable rail can slide before and after retaining rail is done, this activity rail tiltedly is provided with a start groove in end edge to the back upper place, and connect the flaring groove of a perforation activity rail rear end in start groove top, this flaring groove is corresponding with the length of the preceding pod of slide block, and tightening latch can be in flaring groove, the turnover of start groove of movable rail under preceding pod restriction before making.

Slide block has opposing backside surface, front, and the slide block back side is overlapped on the lock front, and the slide block back side this preceding pod, the back pod that are provided with tee-section at interval, and this preceding pod length is corresponding with the flaring groove, and makes its degree of depth can be through to the slide block front; Tightening latch has the outer bar in outstanding slide block front before aforementioned, and the interior bar at the outstanding slide block back side, and bar is in the translot slippage in this; Aforementioned back tightening latch has the outer bar in outstanding slide block front, and the interior bar that protrudes the slide block back side, and the interior bar of this back tightening latch is along translot, upward slippage between fork pockets, following fork pockets and clamping groove.

This lock has opposing backside surface, positive, make translot, last fork pockets, following fork pockets, clamping groove is arranged with the front in lock respectively, and make fork pockets, following fork pockets junction is lower than translot, and order should be gone up fork pockets, following fork pockets, be formed with a wedge between the clamping groove, be equipped with an extension slot to the back lower place in addition and go up the fork pockets rear end, this extension slot opening just is positioned at the clamping groove scope, this wedge is the dovetail shape in the wall of clamping groove, and in clamping groove, be formed with recessed holding section, and this holding section is positioned at the oblique below, opposite of extension slot opening, then be provided with fork pockets down as for clamping groove in extension slot opening below after the guide surface tiltedly established of extreme direction.

This slide block is equipped with spring base up and down respectively in leading edge, this spring base has the appearance hole of running through, and in holding the hole, be provided with the button piece, in this appearance hole, a spring is installed respectively, this spring rear end edge and have the external diameter constriction and the back button portion that can fasten for the button piece, this spring front-end edge has the preceding portion that buckles of external diameter constriction; Lock is respectively equipped with up and down in front-end edge can be for the block of sliding block spring seat location, and this block then has the involutory spring housing of ammunition feed spring front-end edge, and with spring before the abaculus of the portion's of button combination.

Adopt said structure, the utility model can see through the control mode of twice pushing, the function of use that reaches automatic unlatching and seal drawer really, and the utility model mainly makes slide block, lock be a modular configuration with linear slide rail, and then make when this linear slide rail is mounted to furniture, drawer relative position, can finish integral installation, its the assembling far beyond on take off patent before case more convenient and quick, and can not account for the usage space of furniture, drawer, so the utility model really has real benefit.
