Description

But a kind of desk of plug-type extended desktop

Technical field

The utility model relates to a kind of desk, but particularly a kind of desk of plug-type extended desktop.

Background technology

The extendible desk of desktop, desk is in rounding state at ordinary times, takes up room reducing, and during use, then desktop is opened, and enlarges the usable floor area of desktop, and this desk is subjected to people's favor by force because of its practicality.Chinese patent once disclosed a kind of name and had been called " the plug-type automatic lifting multiaspect of modified is shared a table with stranger ", utility model patent (patent No. is: 02288945.0), the desk of this technical scheme mainly is made up of the top table face at two ends, middle auxilliary desktop and table frame, the top table face has slide bar, gag lever post, and the tray with lifting support is housed on the slide bar; Under the auxilliary desktop elevator, locating piece are housed, are shaped on locating slot on the locating piece with high-order locating surface and low level locating surface; Be provided with slide bar groove, crossbeam, positive stop strip, slide rail, keeper etc. on the table frame, this table structure is very complicated, and linkage part is various, be easy to break down, and cost of manufacture is too high.

Summary of the invention

But the purpose of this utility model is to provide the desk of a kind of simple and reasonable, low this one-tenth, plug-type extended desktop that serviceability is stable.

The purpose of this utility model is achieved in that a kind of desk, comprise the telescopic top table face in two ends, middle auxilliary desktop and supporting leg frame, the column and the supporting leg frame two ends of top table face bottom, described two ends flexibly connect by slide rail respectively, the top table face can be divided right and left or closes up to the centre along slide rail, it is characterized in that: the front beam of described supporting leg frame, rear cross beam is a hollow structure, front beam, be respectively equipped with an elevating mechanism in the rear cross beam cavity, described elevating mechanism comprises a pull bar, one slide block, the slide block upper surface is provided with two and has the inclined plane, lift the limiting stand of face, front beam above limiting stand, the relevant position has jack in the middle of the rear cross beam, and the column of auxilliary desktop is installed in the jack; The relevant position, below that described front beam, rear cross beam bottom are positioned at slide block has the strip groove, and the pull bar upper end is connected with slide block, and stretch out from the strip groove after passing the strip groove lower end.

Good effect of the present utility model: the column and the supporting leg frame two ends of two ends top table face bottom flexibly connect by slide rail respectively, the slide block that has the inclined plane, lifts the face limiting stand is installed in the front beam of supporting leg frame, rear cross beam, the column of auxilliary desktop is positioned at the slide block top and is connected with the slide block contact, the slide block bottom connects pull bar, auxilliary desktop makes auxilliary desktop column be positioned at the slide block upper surface by mobile pull bar control slide position or limiting stand lifts on the face, finishes to raise or the auxilliary desktop process of reduction.When top table when two ends are drawn back, the auxilliary desktop that raises is drawn close the two ends top table again towards the centre, be close to auxilliary desktop and can finish the desktop expansion process; Otherwise, after auxilliary desktop reduction, two ends top table face is connected together, can dwindle desktop, take up room with reduction.This table structure is simple, and parts are less, so the probability that breaks down seldom, serviceability is stable, and production cost is lower.

The pull bar lower end is provided with auxiliary pull bar, like this during the auxilliary desktop of lifting, removes mobile pull bar at the bottom of just need not to get into, and directly the side from table is pulled outwardly auxiliary pull bar, just can just push away inward and can reduce auxilliary desktop assisting the desktop rise, and is easy to operate.

The slide block rear end is provided with a power-assisted thrust spring, and when auxiliary pull bar drew outward, the power-assisted thrust spring made slide block move to foremost, auxilliary desktop is positioned at lifting on the face of limiting stand, make auxilliary desktop rise to peak, when guaranteeing the desktop expansion, top table face, auxilliary desktop are positioned at same level height.
