Pull-out table
Technical field
The present invention relates to daily household goods, exactly is to have adjustable function to reduce the dining table that main table top takes up room.
Background technology
Existing circular dining table is placed in and can takies bigger space when indoor, to this, has just occurred some foldable circular dining tables and some telescopic Nogata dining tables on the market, but these dining tables have only paid attention to saving the function in space, have a lot of weak points:
1) face that unfolds of circular foldable dining table mostly connects with hinge, can stir up and down, roll up the back to prop up,, just make the face of unfolding turn down easily if bump against cork because of carelessness with cork, also want extreme care when unfolding face putting down, clip to finger otherwise hold, have certain potential safety hazard, and be out of shape because of scale error or climatic effect easily, main table top with unfold face and be uneven, can't adjustment;
2) telescopic Nogata dining table mostly adopts gear to make slide rail, and desktop can two-wayly extend, and in the time of need adding large table surface, with the two-way extension of desktop, a drop front is added in the centre.When this dining table need not strengthen at ordinary times, the intermediate active panel was hidden in the desktop below, in use, often has some and spills thing below the slit of two desktops flows to dining table, is difficult to cleaning.
Summary of the invention
At the deficiency that prior art exists, the present invention aims to provide a kind of safe, practical and easy operating, contraposition pull-out table accurately.
For achieving the above object, the technical solution used in the present invention is:
A kind of pull-out table, comprise main table top and the movable table top of two concealed semicircles that can be combined into the full circle table top with main table top, main table top thereunder both sides is provided with wooden special-shaped rail, gong goes out a S shape near a centre inclination of gong up of the straight-line groove of its lower edge, straight-line groove and props up groove, straight-line groove front end barb groove of gong is as the rail track up on the wooden special-shaped rail, and the movable table top thereunder front and back of both sides is equipped with two bearings that match with the rail track.
The below of described main table top and movable table top seam crossing is provided with a baffle plate that can spin upside down and block movable table top.
The support of described main table top below is provided with the set screw of lifting master table top.
Described wooden special-shaped rail is installed in the support inboard of main table top below, and bearing is installed in the support outside of movable table top below.
The support of described movable table top below is shaped as frame, is made up of the cross bar of twice side plate and connection side plate, and bearing is installed in the outside of side plate.
Described two semicircle table tops are the center symmetric arrangement with main table top.
The present invention is when paying attention to outward appearance, take the movable table top of concealed semicircle, realize the function of expansion table-board with the cooperation of bearing and wooden special-shaped rail, the shape of wooden special-shaped rail is made through taking into full account mechanics principle, precision is quite high, and but main table top has regulatory function, when finding that movable table top of semicircle and main table top are uneven, can pass through set screw lifting master table top, make it level one to because main table top is a whole plate, so can not influence cleaning work because of spilling etc., compare with traditional adjustable dining table, have following outstanding beneficial effect:
1) save parking space, practical;
2) easy to operate, security good, can prevent tong when flexible;
3) table top residue leftovers is cleared up easily;
4) main table top can suitably be finely tuned, guarantee with expansion table-board level one to.

The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
Description of reference numerals is as follows:
1. main table top 2. movable table tops
3. wooden special-shaped rail 4. straight-line grooves
5.S shape is propped up groove 6. barb grooves
7. baffle plate 8. set screw
Shown in Fig. 1~7, this pull-out table is mainly by main table top 1 and can be combined into the movable table tops 2 of the concealed semicircles of two of full circle table top with main table top and form, two semicircle table tops 2 are that the center is symmetrically arranged with main table top 1, the main table top 1 thereunder support of both sides is provided with wooden special-shaped rail 3, gong goes out a straight-line groove 4 near its lower edge on the wooden special-shaped rail 3, the S shape of the centre of a straight-line groove inclination of gong is up propped up groove 5, the straight-line groove front end up barb groove 6 of gong as the rail track, movable table top 2 is equipped with two bearing (not shown)s that match with the rail track in the front and back of its support both sides, the side of main table top 1 has a baffle plate 7, after two traveling table reductions of area get up, with upwards upset of baffle plate 7, can play the function of hiding movable table top, the support of main table top below is provided with the set screw 8 of lifting master table top.
Movable table top of the present invention can prolong track and realize flexible, lifting, locking function.When traveling table during towards out-draw, front and back bearings begins to advance along the below straight-line groove, when movable table top is pulled out soon, fore bearing begins along the lifting that makes progress of a middle track, when movable table top was all pulled out, rear bearing began to enter the lifting that makes progress of barb track, and final bearing is fallen in the barb groove.At this moment whole table top raises, and is parallel with main table top, because a track tilts, fore bearing just can inwardly produce one pulling force, and movable table top and main table top are close to, and is not easy outwards to move, and cooperates the barb groove, reaches the function of locking activity table top.
This dining table requires each link will be connected finely technically, the part dimension required precision is very high, and certain error can be arranged all in the middle of actual production, so after table top is drawn out, can there be rugged phenomenon in movable table top with main table top, but therefore in main mesa designs regulatory function, can be by the set screw under the adjusting table top, make main table top lifting, reach with activity table-surface level one to effect.
The present invention is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.Though but on its shape or structure, do any variation, every identical with the present invention or akin technical scheme is all within its protection domain.
