Description
Technical field
The utility model relates to a kind of intelligent electric without oily lifting column.
Background technology
The application of society lifting column is more and more extensive, and the desk, chair, sick bed etc. of public arena as office, hospital etc. are elevated as required.Along with the needs of social development, the requirement of people to lifting column is also more and more higher.But the lifting column ubiquity volume of prior art is large, complex structure, manufacturing cost are high and the shortcomings such as easy break-down.
Summary of the invention
The purpose of this utility model is: provide that a kind of structure is simple, volume is little, low cost of manufacture and stable performance can only be electronic without oily lifting column.
The utility model solves the technical scheme that its technical problem adopts: a kind of intelligent electric is without oily lifting column, comprise outer column, inner column, base, screw component, motor, outer column and inner column are the structure that cross section is rectangle and inner hollow, inner column is fixed on base, it is outer and slide up and down with inner column and coordinate that outer column is enclosed within inner column, motor is arranged in base, the rotating shaft of motor is connected with worm screw, worm screw is engaged with worm gear, screw component is arranged in inner column, screw component comprises the out screw rod and interior screw mandrel that cooperatively interact, interior screw mandrel is placed in the centre bore of out screw rod, the lower end of out screw rod is engaged with worm gear, the upper end of interior screw mandrel and the top of outer column offset.
The utility model compared with prior art, have the following advantages: the utility model intelligent electric drives out screw rod to rotate without oily lifting column by motor, the rotation of out screw rod drives the lifting of internal thread bar, the lifting of interior screw mandrel will withstand outer column synchronization lifting, the elevating function of lifting column is realized with this, the utility model intelligent electric is simple without oily lifting column structure, volume is little, low cost of manufacture and stable performance, not easy break-down.
As preferably, described inner column and base are the integrated formed structure that steel are made.Adopt this structural design, effectively can improve the stability of inner column, thus improve the stability of whole lifting column, entirety is not easily toppled over.
As improvement, the outer wall of described outer column is provided with microcontroller, displacement transducer and display screen, microcontroller is connected with displacement transducer, display screen respectively.Adopt this structural design, when outer column is elevated, the displacement signal that displacement transducer can will detect, namely the altitude signal of outer column passes to microcontroller, and show corresponding height value by display screen, so, user just can be allowed to get information about very much the height of lifting column lifting, a reference role is played to user.
