Background technology
Desk, chair, sick bed in family, medical place etc. etc., often need to realize the lifting of desk, chair, sick bed etc.,
Meet different demands.Telescoping tube or expansion link used in general electric elevatable table are mostly three section lifting structures, it
Concrete 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 set in outer tube drives screw rod to rotate, and screw rod is provided with nut, and nut is fixedly connected with inner tube, and inner tube can not
Rotated relative to middle pipe, therefore nut can not follow screw rod to rotate, and along the axial movement of screw rod, so that drive inner tube to stretch,
For example during telescopic tube, inner tube is first moved, and relatively middle pipe is reached after certain size, and pipe continues flexible in driving, until
Middle pipe is also stretched out after nominal length, and motor is stopped, when telescoping tube shrinks, electric motor driven screw, makes nut-screw axially fortune
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 is stopped.It can be seen that whether extending or shortening, the telescoping tube of this structure is all that inner tube is first moved to
Position can just make middle pipe setting in motion, once nut produces loosening with screw rod, inner tube and middle pipe can be caused to loosen together, so passing
It is not fine in terms of dynamic stability and reliability of structure, axial weight capacity is poor.
