For achieving the above object, the technical solution of the utility model be the table top of furniture such as formation desk, bed with one can lifting mechanism fixedly connected, this expansion mechanism be one by the motor-operated mechanical transmission mechanism that can regulate and control.
Described expansion mechanism is provided with a base plate, with the screw vertical fixing at least three screw rods are arranged on the base plate, the all corresponding nut that is rotary with on the every screw rod, these nuts all fixedly are embedded in the bottom hollow pipe of cored screw, the outside of every cored screw bottom all is fixed with a sprocket wheel with key, all respectively be provided with a secondary thrust bearing up and down at each sprocket wheel, below being in sprocket wheel, be provided with a clamping plate below each bearing, the top that is in each bearing of sprocket wheel top is provided with the base plate of middle casing, one group of uniform bolt is fixed the base plate of clamping plate and middle casing, cored screw and clamping plate, directly contact between the base plate of middle casing; The plane vertical fixing is provided with a motor on middle box bottom, the hole during its central shaft passes on the box bottom; Be on the base plate of casing and the motor central shaft between the clamping plate and be fixed with a drive sprocket, be engaged with a ring chain on the drive sprocket with key, chain simultaneously with each sprocket engagement of each cored screw bottom; In the casing of middle casing, be provided with upper box, be fixed with a table top at the top of upper box; On the base plate of upper box, be fixed with corresponding nut in the place corresponding and be spun on the cored screw with each cored screw; Also be fixed with one and have the gag lever post that touches piece on the base plate of middle casing, this bar passes the hole on the upper box base plate; Piece is corresponding, the plane is fixed with a rising limit switch, is fixed with a decline limit switch in the bottom surface of table top on the upper box base plate with touching; Upper box places casing, and middle casing places lower box, and lower box is fixedly installed on the base plate.Rising limit switch and decline limit switch communicate with motor.
Advantage of the present utility model is: in the floor to upholster of furniture such as temporary transient no desk, bed can being contracted, reduce these furniture occupying the interior space.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a structure assembling schematic diagram of the present utility model;
Fig. 2 is the transmission schematic diagram of the utility model sprocket wheel and chain.
In Fig. 1, Fig. 2, the utility model is formed by table top with the mutually affixed elevating mechanism in table top bottom surface, and the elevating mechanism of Table with top of variable height is by the motor-operated mechanical transmission mechanism that can regulate and control.
Described mechanical transmission mechanism is provided with a base plate (16), base plate (16) is gone up has all corresponding nut (9) that is rotary with on every screw rod of four screw rods (10) with screw (15) vertical fixing, nut (9) all fixedly is embedded in the bottom hollow pipe of cored screw (1), the outside of every cored screw (1) bottom all is fixed with a sprocket wheel (7) with key (6), all respectively be provided with a secondary thrust bearing (5) up and down at each sprocket wheel (7), (8), below each bearing (8), be provided with a clamping plate (16), the top of bearing (5) is provided with the base plate of middle casing (2), one group of uniform bolt (11) is fixed the clamping plate (17) and the base plate of middle casing (2), cored screw (1) and clamping plate (16), directly do not contact between the base plate of middle casing (2); Last plane vertical fixing at middle casing (2) base plate is provided with a motor (19), its central shaft (12) passes the hole on the base plate of middle casing (2), the base plate and the motor central shaft (12) between the clamping plate (16) that are in casing (2) upward are fixed with a drive sprocket (14) with key (13), be engaged with a ring chain (18) on the drive sprocket (14), chain (18) engagement of each sprocket wheel (7) bottom each cored screw (1) simultaneously; In the casing of middle casing (2), be provided with upper box (3), be fixed with a table top (23) at the top of upper box (3); On the base plate of upper box (3), be fixed with corresponding nut (4) in the place corresponding and be spun on the cored screw (1) with each cored screw (1); On the base plate of middle casing (2), also be fixed with one and have the gag lever post (20) that touches piece (24), this bar passes the hole on upper box (3) base plate, and touches that piece (24) is corresponding, the plane is fixed with a rising limit switch (21), is fixed with a decline limit switch (22) in the bottom surface of table top (23) on the base plate of upper box (3); Upper box (3) places casing (2), and middle casing (2) places lower box (25), and lower box (25) is fixedly installed on the base plate (16); Rising limit switch (21) and decline limit switch (22) communicate with motor (19).
