A kind of Multifunction test table
Technical field
The utility model relates to a kind of Multifunction test table.
Background technology
Often theory and practice is gathered together in the present teaching process, said the theoretical practical operation of carrying out at once.This just has higher requirement to laboratory table, and laboratory table function now is too single, often can not satisfy all demands of teaching.
The utility model content
The utility model purpose is to provide a kind of for the defective that prior art exists both can use as conventional tables, and it has smooth table top, puts the drawer of article etc., and the dismounting laboratory table that can be used as again specialty uses.Satisfy the dual requirements of theory teaching and practical teaching.
The utility model for achieving the above object, adopt following technical scheme: a kind of Multifunction test table, comprise the desk body, the table top intermediate arrangement of described desk body has lifting column moving up and down, the blind hole cooperation that arranges in the upper end of described lifting column is equipped with turntable, and the turntable bottom is provided with thrust bearing, and turntable relatively lifting column rotates, be provided with the lifting mechanism that cooperates installation with telling lifting column below described desk, described lifting mechanism promotion lifting column is done and is moved up and down.
Described lifting mechanism comprises screw rod, base and motor, is inserted into the screw rod in the base holes bottom described motor drives by worm screw, worm gear, driving gear and the driven gear that cooperates installation successively, does moving up and down; Screw rod promotes lifting column and does movement up and down.
Preferably, described driven gear is by base support.
Preferably, the head of described screw rod is hemispherical, and installation matches in its hole with described lifting column bottom.
Preferably, the cross sectional shape of described lifting column is square.
The table top of described desk is square, is provided with drawer on each direction, and described drawer is distributed in the table top both sides.
The beneficial effects of the utility model: this desk can be worked as common laboratory table and be used, and can be for conversion into again dismounting, the demonstrating experiment table of specialty, and is simple in structure, easy to use.
Description of drawings
Fig. 1 front view of the present utility model;
Fig. 2 top view of the present utility model;
Among the figure, 1, table top, 2, drawer, 3, turntable, 4, thrust bearing, 5, lifting column, 6, screw rod, 7, base, 8, worm screw, 9, worm gear, 10, driving gear, 11, driven gear, 12, motor.
The specific embodiment
Illustrated in figures 1 and 2, table top 1 intermediate arrangement of desk has lifting column 5, and the cross sectional shape of lifting column 5 is square, and assurance lifting column 5 can only be done movement up and down, can not rotate.Upper surface at lifting column 5 is combined with turntable 3, turntable 3 relative lifting columns 5 can rotate, turntable 3 bottoms are thrust bearing 4, thrust bearing 4 is arranged in the bottom of lifting column 5 upper aperture, can place the part of dismounting, demonstration on the turntable 3, just can easily rotating part by rotating turntable 3, drawing can be placed in four sides after lifting column 5 rises, but limit trimming with the aid of pictures dismounting.Because dismounting, demonstration part only have pressure to turntable, so only be provided with the thrust bearing 4 that can only bear axial force.1 pair of lifting column 5 of table top plays the effect of guiding.The table top 1 of desk is square, is provided with drawer 2 on each direction, and drawer 2 is distributed in both sides, and the centre is the place of operation, and in the middle of the people stood in like this, instrument etc. were placed in the drawer of both sides, and dismounting, study are got up very convenient.
Lifting mechanism is positioned at the centre position, below of table top, and it is comprised of screw rod 6, base 7, worm screw 8, worm gear 9, driving gear 10, driven gear 11, motor 12 etc.Worm screw 8 directly connects motor 12, by cooperating of worm screw 8 and turbine 9, reduces the rotating speed of motor 12, and worm screw 9 is coaxially connected with driving gear 10, and driving gear 10 cooperates with driven gear 11, reaches two-stage speed-down.Driven gear 11 has base 7 to support, and the centre of driven gear 11 is internal thread, and the internal thread of driven gear 11 cooperates with screw rod 6, and screw rod 6 is inserted in the hole of base 7, driven gear 11 rotations, and screw rod 6 is done and is moved up and down.The head of screw rod 6 is hemisphericals, and it is inserted in the hemispherical-shaped aperture of lifting column 5 bottoms, and screw rod 6 promotes lifting column 5 and does movement up and down.
When laboratory table need to be worked as the conventional tables use, fall lifting platform 5 and get final product.When needs use as disassembly-and-assembly stand, rise lifting column and get final product.The connection and reasonable arrangement such as placement of simple in structure, drawer, drawing, easy to use.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
