Abstract
The utility model discloses an electric lifting mechanism for a desk and a chair, which comprises a base, a motor, a motor switch, a lead screw and a main rod, wherein the motor is arranged on the base, in addition, whether the motor works or not is controlled by the motor switch, the screw rod is vertically arranged above the base, the lower end of the screw rod is connected with the motor and is driven by the motor, the upper end of the screw rod is in connection transmission with the lower end of the main rod, and the upper end of the main rod is arranged under the desk and the chair. Wherein the motor switch controls the motor to start to work, the motor drives the screw rod, and the main rod is driven to ascend and descend through the matching of the screw rod and the main rod, so the desk and the chair arranged at the upper end of the main rod is driven to ascend and descend. The electric lifting is adopted for replacing the hydraulic and pneumatic lifting, the labor and the time are saved, in addition, the screw rod is in transmission lifting, the continuous stepless regulation is realized, and the lifting operation is very convenient.
Description
Technical field
The utility model relates to lifting technology, and is relevant with the electric lifting mechanism of tables and chairs.
Background technology
In the prior art, the lifting of reason appearance tables and chairs etc. adopts hydraulic cylinder or pneumatic cylinder to realize mostly.Need constantly jam on pedal during lifting, tables and chairs be risen by oil pressure or air pressure.So operation is wasted time and energy, and always a section carries out apart from the ground jump during lifting, and lifting realizes trickle electrodeless adjusting continuously.Therefore, the inventor develops a kind of electric lifting mechanism of tables and chairs specially, and this case produces thus.
The utility model content
The purpose of this utility model provides a kind of electric lifting mechanism of tables and chairs, with the easy of rise operation, and realizes electrodeless lift adjustment continuously.
In order to reach above-mentioned purpose, solution of the present utility model is:
The electric lifting mechanism of tables and chairs, comprise base, motor, motor switch, screw mandrel and mobile jib, motor is installed on the base and by motor switch whether control machine operation, screw mandrel vertically is arranged on the base top, the lower end of screw mandrel is connected with motor and by the motor transmission, the upper end of screw mandrel is connected transmission with the lower end internal thread of mobile jib, and the upper end of mobile jib is installed in the below of tables and chairs.
Described mechanism also comprises positioning seat, main body, guide pillar and portable plate, positioning seat is fixed on the base, main body is fixed on the positioning seat, screw mandrel interts in main body after passing the through hole of positioning seat, guide pillar is arranged in the main body, portable plate is arranged in the main body and is nested with on guide pillar, and portable plate is connected the lower end of mobile jib, and mobile jib passes from the through hole of main body top.
The above and below is respectively equipped with to cooperate with portable plate and controls out-of-work upper limit position switch of motor and lower position switch in the described main body.
The through hole of described main body top is with copper sheathing.
Described guide pillar has two to four.
Electric heating tube also is installed in the described main body, is offered passage on the main body.
After adopting said structure, the utility model is to control the tables and chairs lifting like this, and by motor switch control motor unlatching work, motor is transmitted in screw mandrel earlier, cooperate by screw mandrel and mobile jib again to drive mobile jib rising or decline, drive the tables and chairs lifting that is installed in the mobile jib upper end thus.The utility model replaces hydraulic pressure and pressure liftable by electric up-down, laborsaving saving time, and, screw mandrel transmission lifting, continuous electrodeless adjusting, descending operation is very convenient.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
