Description
Technical field
The utility model relates to lifting technology fields, more particularly to a kind of synchronization lifting push rod device and its desk.
Background technique
Desk, chair, hospital bed etc. in family, medical place etc., often need to realize the lifting of desk, chair, hospital bed etc.,
Meet different demands.Telescoping tube used in general electric elevatable table or telescopic rod are mostly three section lifting structures, it
Specific structure is usually, including inner tube, the tube and the outer tube, in the rear end insertion of inner tube in pipe, in the rear end insertion outer tube of middle pipe,
Then the motor being arranged in outer tube drives screw rod rotation, and screw rod is equipped with nut, and nut is fixedly connected with inner tube, and inner tube can not
It is rotated relative to middle pipe, therefore nut can not follow screw rod to rotate, and along the axial movement of screw rod, thus drive inner tube flexible,
Such as when telescopic tube, inner tube is first moved, and after relatively middle pipe reaches certain size, be will drive middle pipe and is continued to stretch, until
After middle pipe also stretches out nominal length, motor stops working, and when telescoping tube is shunk, electric motor driven screw transports nut-screw axially
It is dynamic, drive inner tube to retract, when inner tube is retracted to the setting position of middle pipe, middle pipe starts to retract, until middle pipe is retracted into outer tube
Setting position, motor stop working.It can be seen that whether extending or shortening, the telescoping tube of this structure is all that inner tube first moves to
Position can just make middle pipe setting in motion, once nut and screw rod generate loosening, will lead to inner tube and middle pipe loosens together, so passing
It is not very well in terms of dynamic stability and reliability of structure, axial load-bearing capacity is poor.
