Side inner wall, thus using frictional force by 19 clamping fixed of T-block.
When use: the rotation axis rotation of starting motor 1 drives the first transmission to drive driving gear 2 to rotate, and then pass through
One transmission gear 6 of the downside on axis 4 rotates, and then, a transmission gear 6 of downside drives one on second driving shaft 5
A transmission gear 6 rotates, to realize first order deceleration；Then a transmission gear 6 on second driving shaft 5 drives again
One transmission gear 6 of the upside on one transmission shaft 4 rotates, so that second level deceleration is realized, and so on, if there is needing
It wants, the transmission gear 6 of identical quantity can be sequentially overlapped on the first transmission shaft 4 and second driving shaft 5, appoint so as to realize
The deceleration of meaning series, as long as and using the transmission gear of same specification 6, easy to operate, manufacturing cost is low；First passes
One transmission gear 6 of the top side on moving axis 4 finally will drive the rotation of output gear 9, so that driving lead screw 10 is in axis
Hold in 11 and rotated together with output gear 9, thus by be threadedly coupled principle drive feed screw nut 13 inside profile 12 back and forth
Sliding, the other end that the movement of feed screw nut 13 will drive telescoping tube 14 move back and forth in limit base 16, and then drive pull head
15 move back and forth, and when the outer end of feed screw nut 13 resists the inside of limit base 16, pull head 15 is moved outwardly to maximum distance；It borrows
It helps the matched connector outer end of T-block 19 is rotatably coupled in corresponding mechanism, pull head 15 can be made to move back
It drives profile 12 to realize rotation by T-block 19 in dynamic, this structure is applied on swing mechanism, to expand this knot
The application range of structure；Fixation position of the T-block 19 on profile 12, which can according to need, to be slid back and forth to realize and adjust, and is adjusted
Two Top fastening screws 20 are tightened after section；Lubricating oil can be added to by the second threaded hole 123 by unloading straight-bar screw 18
In telescopic hole 122；The gas that gas vent 181 can will pass through inside telescopic hole 122 is discharged to the outside, and is prevented because through flexible
Cause feed screw nut 13 to slide unsmooth phenomenon in hole 122 there are air pressure to generate；Multiple screw threads are provided on driving lead screw 10,
And multiple screw threads are the prior art, the benefit that multiple screw threads and feed screw nut 13 are mutually spirally connected is to greatly reduce feed screw nut 13
With the gearing friction power between driving lead screw 10, when motor 1 is in close state, push-and-pull feed screw nut 13 can corresponding band
Dynamic driving lead screw 10 rotates, and feed screw nut 13 is not had in manual movement whenever necessary by electric power.
Electric pushrod also known as linear actuator are a kind of linear reciprocation fortune that the rotary motion of motor is changed into push rod
Dynamic power-driven gear can be used for as mechanical use is executed in various simple or complicated process flow, to realize long distance
From control, centralized control or automatic control；It is widely used as the movement driving of household electrical appliance, kitchen tools, medical instrument, automobile and other industries
Unit；The reduction gearbox of existing electric pushrod mostly uses the kind of drive of turbine and worm to slow down, in order to increase reduction ratio
Turbine diameter must just be done greatly, accompanying problem is that causing volume larger, can not electric pushrod be applied some
On the lesser product in space, smaller scope of application, and in order to cooperate reduction ratio also to increase the power of driving motor, it is bound to
Cause further increasing for volume；Meanwhile turbine do big, electric pushrod volume become larger and the increase of driving motor power all
It is more, at high cost to will cause product materials；In addition, the driving lead screw of existing electric pushrod contains only one start screw, therefore lead screw
Gearing friction power between nut and driving lead screw is very big, when driving motor breaks down or is in off-position, lead screw spiral shell
Mother will stop at always original position, and Manual push-pull feed screw nut does not have any effect；The present invention is using eccentric setting
The mode that gear is overlapped mutually transmission is slowed down, and volume is substantially reduced, and expands the scope of application；The adjusting of reduction ratio can be with
It is realized by increasing or decreasing the quantity of transmission gear 6, it is easy to operate；And transmission gear 6 need a kind of the straight of fixation
Diameter specification, it is at low cost, it suits large area to popularize；Meanwhile driving lead screw 10 containing 5 or more screw threads, greatly reduce
Gearing friction power between feed screw nut 13 and driving lead screw 10, when driving motor breaks down or when in off-position,
As long as with little power can Manual push-pull feed screw nut, the further expansion scope of application；In addition, the setting for passing through T-block
The present invention is applied in the field that straight line is combined with revolution driving, the scope of application is further expanded, T-block
Fixed position is adjustable, so that the radius of gyration is adjustable, it is easy to adjust.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
