Abstract
The invention provides a synchronous lifting rod assembly of a lifting table. change the mode combined with inner tube, middle pipe and outer tube by conventional lifting structure, the function of synchronization lifting is realized by the combined structure of double nuts, double screws and double bushings, structure design is compact and reasonable, separate with inner tube, middle pipe and outer tube, be not in because nut is strengthened in terms of producing loosening, the situation that inner tube and middle pipe loosen together, the stability of transmission and reliability of structure with screw rod; the internal screw is arranged at the upper part, and pressure is concentrated on the lower bushing with larger cross section, so that the stability of the assembly is improved and cannot deform for long-time pressure bearing, and the service life of the nuts and the screws is prolonged; by means of the integrated structure, only the assembly is required to be disassembled for examination in case of problems, the inner tube, the middle tube and the outer tube are basically not affected, the maintenance cost is low, and operation is facilitated.
Description
Technical field
The present invention relates to same table technical field, the synchronization lifting screw component of more particularly, to a kind of same table.
Background technology
Telescoping tube used in general electric elevatable table or expansion link are mostly three section lifting structures, its concrete knot
Structure is usually, including inner tube, the tube and the outer tube, in pipe in the rear end insertion of inner tube, in the rear end insertion outer tube of middle pipe, Ran Hou
The motor of setting drives screw rod to rotate in outer tube, and screw rod is provided with nut, and nut is fixedly connected with inner tube, inner tube cannot relatively in
Pipe rotates, and therefore nut cannot be followed screw rod and be rotated, and the axially-movable along screw rod, thus driving inner tube to stretch, for example, stretch
During draw elongation, inner tube is first moved, and after relatively middle pipe reaches certain size, disorder of internal organs pipe can be carried to continue flexible, until middle pipe
After stretching out nominal length, motor quits work, when telescoping tube shrinks, electric motor driven screw, and make nut-screw axially-movable, drive
Inner tube is retracted, and when inner tube is retracted to the setting position of middle pipe, middle pipe starts to retract, until middle pipe is retracted into the setting position of outer tube
Put, motor quits work.It can be seen that whether elongation or shortening, the telescoping tube of this structure is all that inner tube is first moved the just meeting that puts in place
Making middle pipe setting in motion, once nut is produced with screw rod loosening, inner tube can be led to loosen together with middle pipe, thus steady in transmission
Qualitative and reliability of structure aspect is not fine, and axial weight capacity is poor.
There are the technical scheme of the telescoping tube of synchronization lifting, such as Publication No. 104254264a, publication date before the application
Chinese patent for 2014-12-31 discloses a kind of lifting column, comprising: guiding piece, described guiding piece include first component,
Two parts and third member, they are arranged to intussusception each other；And mandrel unit, described mandrel unit includes: the first heart axle,
On the end of first component that described first heart axle is fixed on guiding piece by end；Second heart axle, described second heart axle tool
There are the first spindle nut being fixed on its end, described first spindle nut and the cooperation of the first heart axle；Second spindle nut, institute
State the second spindle nut to be fixed against rotating, and coordinate with the second heart axle；Driving tube, described driving tube is joined with the second heart axle
Close, for driving the second heart axle；And the first component of clutch, it is located at the upper end of driving tube；And motor unit, institute
State motor unit and have and reversible electric motor and actuating device, wherein, described actuating device has the second component of clutch, is used for
Coordinate with the first component of the clutch of the upper end in driving tube, for driving first component；The second component of guiding piece leads to
Cross lower end and be fixed on the lower end of the second heart axle, passed through using rigid connector with the second spindle nut of the second heart axle cooperation
Clutch shaft bearing and be fixed on short, described short axle is fixed to the end of driving tube, and short axle is fixed by second bearing.But this
The lifting column of kind of structure manage in the first spindle nut and the second spindle nut are separately fixed at inner tube on, cause to generate this
During lifting column, the first spindle nut and the second spindle nut are assembled with middle pipe and inner tube respectively, but also will be with the first heart axle
Coordinate with the second heart axle, generate difficulty greatly, efficiency is very low；And the first thinner heart axle position in lower section as support, certainly will be right
The stability of whole lifting column is unfavorable, and long-term pressure-bearing, once deforming, all can cause permanently to damage to nut and screw rod
Wound, and because the complexity of its structure is higher, overhaul relatively difficult, changing nut needs by inner and outer tubes together
Change, maintenance cost is very high.
Content of the invention
The technical problem to be solved in the present invention is: for the existing at present elevating mechanism for electric elevatable table in transmission
Stability and reliability of structure aspect Shortcomings, and exist structure complexity higher, maintenance get up comparison be stranded
Difficulty, changing nut needs to change inner and outer tubes together, the problems such as maintenance cost is very high, the invention provides a kind of lifting
