Description
Technical field
The utility model relates to lifting column technical field, in particular to a kind of three section upside-down mounting screw rod of simple type lifting is vertical
Column.
Background technique
Electric lifting vertical column is widely used in the fields such as household, medical treatment.
Lifting column in the prior art, when manufacturing, since structure is complicated, causing its production cost, also water rises ship
Height, it is some require more wide in range use occasion under, structural strength far beyond required structural strength in use,
Cause the waste of material, time and cost.
Utility model content
The purpose of the utility model is to provide a kind of three section upside-down mounting screw rods lifting of structurally reasonable, cost bottom simple type is vertical
Column.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of three section of simple type falls
Screw rod lifting column, including inner tube are filled, lower nut is provided in inner tube, middle pipe is arranged with outside inner tube, is arranged with outer tube outside middle pipe,
It is provided with top nut on the upper end inner wall of the middle pipe, bearing is provided in top nut, hollow screw rod is provided in bearing, it is hollow
Screw rod is threadedly coupled with lower nut, and motor is provided on outer tube, and minor leading screw, the lower thread connection of minor leading screw are provided on motor
In lower nut, keyway is provided in hollow screw rod, the bottom of minor leading screw is provided with the spline being adapted to keyway.
By using above-mentioned technical proposal, relatively traditional lifting column, the utility model is by the direct screw thread of hollow screw rod
It connects on inner pipe, so that its consumption that can reduce material, and simplify operation when installation, increase efficiency.
It is further arranged to: being installed with one in said inner tube and determine nut, hollow screw rod is connect with nut thread is determined.
By using above-mentioned technical proposal, lower nut limits hollow screw rod with nut resultant force is determined, thus in slowing down
Empty screw rod is squeezed caused by lower nut when rotating, so that lower nut is still able to maintain stabilization after long-term use, increases the liter
The reasonable structure of column drops.
It is further arranged to: being provided with fixture block on the upper end outer wall of inner tube, be provided on the lower end inner wall of middle pipe and fixture block
The vertical slots of adaptation.
By using above-mentioned technical proposal, when relative displacement occurs between each other for inner tube and middle pipe, enable to middle pipe with
Displacement between inner tube is more stable.
Be further arranged to: the middle position of the lower nut is provided with extended segment, is provided on the peripheral wall of extended segment perpendicular
Straight stiffener.
By using above-mentioned technical proposal, extended segment is plugged in inner tube, when so as to slow down lifting column lifting
The lateral pressure to lower nut that may cause, to increase the service life of lower nut.
Detailed description of the invention

Specific embodiment
The utility model is described in further detail below in conjunction with Fig. 1 and Fig. 2.
A kind of three section upside-down mounting screw rod lifting column of simple type, including inner tube 1, middle pipe 3 and the outer tube 4 being arranged from bottom to top,
Outer tube 4 is set in outside middle pipe 3, and middle pipe 3 is set in outside inner tube 1.
4 upper end of outer tube is provided with downward motor 7, and middle 3 upper end of pipe is provided with top nut 5, is provided with axis in top nut 5
It holds, minor leading screw 8 is provided in the rotation axis of motor 7, the lower end of minor leading screw 8 is rotatably connected in top nut 5.
It is provided with a bearing in top nut 5, hollow screw rod 6 is installed on the inner ring of bearing, is set on the inner wall of hollow screw rod 6
It is equipped with multiple tracks keyway, the end of minor leading screw 8 is provided with spline, and spline is extended into hollow screw rod 6 and is adapted to keyway.
The upper end of inner tube 1 is provided with lower nut 2, and one is installed in inner tube 1 and determines nut 9, hollow screw rod 6 respectively with lower spiral shell
Mother 2 and determine nut 9 and be connected through a screw thread, to limit on two points hollow screw rod 6, lifting column liter is shared with this
To pressure caused by lower nut 2 when drop, slow down the loss of lower nut 2, increases the service life of lower nut 2.The centre of lower nut 2
Position is provided with extended segment 12, more vertical stiffeners 13 is surrounded on the peripheral wall of extended segment 12, extended segment 12 is set
The conflict length that can increase to hollow screw rod 6 is set, thus to the pressure of the screw thread of lower nut 2 when slowing down the rotation of hollow screw rod 6,
And then guarantee the service life of lower nut 2.
Fixture block 10 is provided on the upper end outer wall of inner tube 1, be provided on the lower end inner wall of middle pipe 3 be adapted to fixture block 10 it is perpendicular
Straight trough 11.When relative displacement occurs between each other for inner tube 1 and middle pipe 3, the limitation of fixture block 10 and vertical slots 11 is set, is enabled to
Displacement between middle pipe 3 and inner tube 1 is more stable.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
