In figure: 1-plug, 2-reducing motor, 3-bearing block, 4-screw rod, 5-shell fragment support, 6-nut seat, 7-telescoping tube, 8-outer tube, 9-PCB bus, 10-guide collar.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1, in this utility model embodiment, a kind of stable electric pushrod, including reducing motor 2, screw rod 4, telescoping tube 7 and outer tube 8；Described reducing motor 2 is arranged in outer tube 8, and outer tube 8 afterbody is provided with plug 1, and plug 1 is for forming the installation cavity for installing miscellaneous part in outer tube 8, it is to avoid miscellaneous part drops in outer tube 8；Described reducing motor 2 front end is provided with bearing block 3, bearing block 3 is fixed in outer tube 8, the output shaft of reducing motor 2 through bearing block 3 drive connection to screw rod 4, by bearing block 3, the orientation of the output shaft of reducing motor 2 is defined, to avoid the output shaft of reducing motor 2 that deflection occurs, thus ensure that this electric pushrod is stable, after reducing motor 2 starts, its output shaft drives screw rod 4 to rotate；Described telescoping tube 7 is slidably mounted in outer tube 8 by guiding mechanism, it is flexible that guiding mechanism makes telescoping tube 7 be only capable of along outer tube 8, and cannot rotate in outer tube 8, telescoping tube 7 afterbody is provided with nut seat 6, the nut bore matched with screw rod 4 is offered in nut seat 6, and nut seat 6 is arranged on screw rod 4 by nut bore, due to nut seat 6 and screw rod 4 threaded engagement, nut seat 6 is fixed on telescoping tube 7, and telescoping tube 7 is only capable of along outer tube 8 flexible under the effect of guiding mechanism, therefore when reducing motor 2 drives screw rod 4 to rotate, mating reaction by screw rod 4 with nut seat 6, telescoping tube 7 is driven to stretch along outer tube 8, thus the rotary motion of reducing motor 2 is changed into the straight reciprocating motion of telescoping tube 7；Described outer tube 8 front end is additionally provided with guide collar 10, offers pilot hole in guide collar 10, and the front end of telescoping tube 7 stretches out through pilot hole, by arranging guide collar 10, not only provide guide effect for telescoping tube 7, it is ensured that electric pushrod is stable, and play sealing effectiveness；It is additionally provided with PCB bus 9 in described outer tube 8.
Operation principle of the present utility model is: described stable electric pushrod, after reducing motor 2 starts, its output shaft drives screw rod 4 to rotate, due to nut seat 6 and screw rod 4 threaded engagement, nut seat 6 is fixed on telescoping tube 7, and telescoping tube 7 is only capable of along outer tube 8 flexible under the effect of guiding mechanism, therefore when reducing motor 2 drives screw rod 4 to rotate, mating reaction by screw rod 4 with nut seat 6, drive telescoping tube 7 to stretch along outer tube 8, thus the rotary motion of reducing motor 2 is changed into the straight reciprocating motion of telescoping tube 7.
Described stable electric pushrod is rationally distributed, by structure optimization, makes each parts run each along respective operation track, does not haves skewness, thus ensure that electric pushrod is stable, and service life is long.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
