Abstract
The utility model relates to a lift table technical field especially relates to an electric lift table's elevating system, including power transmission mechanism and first pipe (1) of cup jointing in proper order, second pipe (2) and third pipe (3), power transmission mechanism is used for driving first pipe (1) vertical removal on second pipe (2) and drives second pipe (2) vertical removal on third pipe (3) simultaneously. Vertical control range broad of this kind of elevating system and governing speed are very fast.
Description
Technical field
The utility model relates to same table technical field, particularly relates to a kind of elevating mechanism of electric elevatable table.
Background technology
Electric elevatable table is the desk that can carry out vertically highly regulating, the electric elevatable table of prior art is two-part lifting structure, an i.e. outer sheathed fall way of stationary pipes, by the movement of fall way, same table is vertically regulated, so vertical height adjustment range is narrower, and governing speed is slower.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of vertical adjustable range wider and the elevating mechanism of governing speed electric elevatable table faster.
The technical scheme that the utility model adopts is: a kind of elevating mechanism of electric elevatable table, comprise power drive mechanism and the first pipe be socketed successively, the second pipe and the 3rd pipe, for driving, the first pipe is vertically mobile on the second pipe drives the vertically movement on the 3rd pipe of the second pipe to described power drive mechanism simultaneously.
Adopt above structure compared with prior art, the utility model has the following advantages: the lifting structure adopting syllogic, such adjustable range is wider than two-part lifting structure, and when motor speed is constant, the lifting structure of syllogic must be faster than the governing speed of two-part lifting structure.
As preferably, described power drive mechanism comprises motor, be connected with motor output shaft and the transmission tube of synchronous axial system, fix and the major thread cover of axial limiting in the first pipe lower end, the big wire role be connected with major thread external threading, to fix with big wire role lower end and axial limiting overlaps at the minor thread of the second pipe lower end and is connected with minor thread external threading and is fixed on the minor leading screw bottom the 3rd pipe with transmission tube lower end, described transmission tube radial direction is provided with the through hole stretched into for big wire role, and described big wire role radial direction is provided with the through hole stretched into for minor leading screw.Adopt the power drive mechanism of this structure, first rotated by driven by motor transmission tube, transmission tube drives major thread cover to rotate, and major thread cover is that axial limiting is in the first pipe lower end, and big wire role is connected with major thread external threading, such major thread cover will drive the first pipe along big wire role vertically movement, and now big wire role self also can rotate, the minor thread cover being fixed on big wire role lower end is driven to rotate, again because minor thread cover axial limiting is threaded with minor leading screw in the second pipe lower end, and minor leading screw is fixed on bottom the 3rd pipe, so now minor thread cover can drive the vertically movement of the second pipe, namely achieve the first pipe vertically to move with identical speed with the second pipe, such adjustable range is larger, and governing speed is very fast, and it is relatively simple for structure.
As preferably, between described first pipe with the second pipe and second manage be provided with catch between the 3rd pipe.Catch is set between two pipes, can effectively prevents dust and other impurities from entering into the work of the whole elevating mechanism of impact in pipe like this.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described further, but the utility model is not limited only to following detailed description of the invention.
A kind of elevating mechanism of electric elevatable table, comprise power drive mechanism and the first pipe 1, second pipe 2 be socketed successively and the 3rd pipe 3, for driving, the first pipe 1 is vertically mobile on the second pipe 2 drives the vertically movement on the 3rd pipe 3 of the second pipe 2 to described power drive mechanism simultaneously.
Described power drive mechanism comprises motor 4, be connected with motor 4 output shaft and the transmission tube 5 of synchronous axial system, fix with transmission tube 5 lower end and axial limiting overlaps 6 at the major thread of the first pipe 1 lower end, overlaps 6 big wire roles be threaded 7 with major thread, to fix with big wire role 7 lower end and axial limiting overlaps 8 and overlap 8 with minor thread and be threaded and be fixed on the minor leading screw 9 bottom the 3rd pipe 3 at the minor thread of the second pipe 2 lower end, described transmission tube 5 radial direction is provided with the through hole stretched into for big wire role 7, and described big wire role 7 radial direction is provided with the through hole stretched into for minor leading screw 9.Described minor thread cover 8 is in the second pipe lower end by two and half slide cover axial limitings.Described first pipe 1 is elliptical tube, and described second pipe 2 and the 3rd pipe 3 are square tube.
Between described first pipe 1 and the second pipe 2 and be provided with catch between the second pipe 2 and the 3rd pipe 3.
Be that minor leading screw 9 stretches in big wire role 7 when same table is adjusted to the shortest time, big wire role 7 extend in transmission tube 5.
