Description
Technical field
The present invention relates to a kind of many screw synchronous electric lifting rod.
Background technology
In prior art, disclose the applicant and declare and obtained the patent of invention of mandate, patent name in July, 2015
For " a kind of multi-thread bar mechanical lifter ", Authorization Notice No. is CN204981006U, and authorized announcement date is 2016.01.20.
Above-mentioned a kind of multi-thread bar mechanical lifter of the prior art, has the lead-screw driving device of body and body, body
Having the many pipes that axis diameter on the same line is nested together from big to small, circular tube external wall has axially directed key, pipe
On upper end, the inner periphery of set has gathering sill；Lead-screw driving device has many pipe leading screws in pipe, an interior pipe
Leading screw is end leading screw, and a pipe leading screw of outermost is push pipe leading screw, and remaining pipe leading screw is inner tube leading screw, end leading screw and interior
The excircle of pipe leading screw has the axial plane formed because machining away axial arch post, push pipe leading screw and the lower end of inner tube leading screw
Having radially pin-and-hole in the mouth of pipe, radially pin-and-hole is embedded with the arch pin that can slide at the axial plane of adjacent inboard leading screw excircle
Block；Being connected with annular between the lower end of described pipe and corresponding pipe leading screw to trap, the epimere of endoporus of trapping has bearing, hypomere to have
Nut, leading screw is connected with the engagement of the adjacent nut trapped.Above-mentioned multi-thread bar mechanical lifter is when lifting, and many pipes are same
Step lifting, the time used during lifting is shorter；The adjacent pipe leading screw of multi-thread bar mechanical lifter driving means is to use arch post
Pin block is connected with radially pin-and-hole and transmits moment of torsion, simple in construction, can allow multi-thread bar mechanical lifter rising maximum height with
Under arbitrary height on.
Above-mentioned multi-thread bar mechanical lifter of the prior art there is the problem that due to end leading screw and inner tube when lifting
The excircle of leading screw is formed with axial plane, therefore when elevating lever rises overally or declines, with end leading screw and inner tube leading screw phase
The nut put under the annular coordinated is easy to wear, and life-time service can cause the thread failure of nut, it is impossible to completes to rise normally
Fall operation；Further, since above-mentioned push pipe leading screw of the prior art and inner tube leading screw are the arch by being loaded on its lower end mouth of pipe
Pin block matches with the axial plane of adjacent inner tube leading screw and end leading screw and carries out upper and lower slip, during slip friction area big,
Add the power consumption of motor.
Summary of the invention
When the technical problem to be solved in the present invention is to provide a kind of lift work, nut is the most easy to wear and can effectively reduce
Drive many screw synchronous electric lifting rod of motor power consumption.
For solving above-mentioned technical problem, many screw synchronous electric lifting rod of the present invention, there is the leading screw of body and body
Driving means, this lead-screw driving device includes many pipe leading screws, in a pipe leading screw be end leading screw, of outermost
Pipe leading screw is push pipe leading screw, and remaining pipe leading screw is inner tube leading screw, and the lower end of leading screw of the described end and inner tube leading screw connects respectively
Having annular to trap, the lower end engagement of described push pipe leading screw is connected with nut, and the upper end of leading screw of the described end and inner tube leading screw is connected with circle
Overlap in annular, annular has feather key vertically on the outer circle wall of set；Said inner tube leading screw and push pipe leading screw interior
There is on wall the axially directed groove matched with described feather key.
Many screw synchronous electric lifting rod of said structure, owing to using the upper end of leading screw of the described end and inner tube leading screw to be connected with
Overlap on annular, annular has feather key vertically, said inner tube leading screw and push pipe leading screw on the outer circle wall of set
There is on inwall the technical characteristic of the axially directed groove matched with described feather key, change end leading screw in prior art, interior
Pipe leading screw and adjacent inner tube leading screw, the pin block of push pipe leading screw and the matching relationship of plane, the end leading screw in the present invention and inner tube
Leading screw need not process axial plane on tube wall, therefore when elevating lever rises overally or declines, with end leading screw and inner tube leading screw
The nut put under the annular matched is the most easy to wear, and life-time service is also not result in the thread failure of nut, it is ensured that
Normal lift work, the present invention is when lift work simultaneously, is by key, slot fit between leading screw, and resistance to sliding is little, reduces
The power consumption of lifter rod lifting.
