Abstract
A spring force-driven dual-drum driving device with low driving speed belongs to the field of driving devices, and aims at solving the problem that the traditional driving device drives an object to move too fast. The utility model adopts a rotary type spring force to drive an object, and is characterized in that the driving device is composed of a dual-drum spring structure comprising an inner sleeve drum, an outer sleeve drum and a torsion spring, the outer sleeve drum comprises a large drum and a small drum sharing the same closed end and the same axis, the inner sleeve drum also comprises a large drum and a small drum sharing the same closed end and the same axis, a cantilever is fixed on the outer surface of the closed end of the outer sleeve drum, a shaft is arranged on the outer surface of the closed end of the inner sleeve drum, is in clearance fit with a shaft hole and is connected with an object to be driven, the large and the small drums of the outer sleeve drum are mutually sleeved with the large and the small drums of the inner sleeve drum, and the torsion spring is fixed between the inner end surface of the closed end of the small drum of the outer sleeve drum and the inner end surface of the closed end of the small drum of the inner sleeve drum. The utility model has the advantages of simple structure and low cost, and can drive the object to move steady and slowly.
Description
Technical field:
The slow drive unit of a kind of bitubular of spring force effect belongs to the driving field, is for object is slowly moved.
Technical background:
Existing spring force drive unit, its principle is that because spring force discharges soon, the object that is applied starts and stops all is to finish moment by the elastic force driving object of spring generation rectilinear direction, therefore can produce the bigger sound and bump, so fragile object and the mood that influences people.Useful afterwards hydraulic principle drives the device of object, but its structure is complicated, and required precision is higher, thereby cost is also high, and installation and maintenance inconvenience, fails generally to use.
The model utility content:
Propose a kind of slow drive unit of the bitubular of spring force effect, its objective is the problem that will solve the too fast motion of driving object that above-mentioned drive unit exists, design a kind of new device that object was not only slow but also can steadily move that makes.
The utility model adopts rotary spring-back force to drive object.
The slow drive unit of a kind of bitubular of spring force effect, comprise spring, it is characterized in that drive unit is made up of the double barreled spring structure, described double barreled spring structure is by inner sleeve, outer sleeve and torsion spring are formed, the structure of outer sleeve be have same closed end and at size two cylinders of same axis, the outer surface of outer sleeve closed end has cantilever, cantilever is fixed, the structure of inner sleeve also be have same closed end and at size two cylinders of same axis, the little drum diameter of inner sleeve is slightly smaller than the little drum diameter of outer sleeve, but be a bit larger tham the torsion spring diameter, and the large cylinder diameter of inner sleeve is a bit larger tham the little drum diameter of outer sleeve, and less than the large cylinder diameter of outer sleeve, the outer surface of inner sleeve closed end has rotating shaft and connects and is driven object, and the big or small cylinder of outer sleeve and inner sleeve is overlapping mutually, and torsion spring is fixed between the interior edge face of roundlet tube closed end of the little cylinder of outer sleeve and inner sleeve.
The slow drive unit of the bitubular of above-mentioned a kind of spring force effect is characterized in that torsion spring is fixed on the spring groove of interior edge face of outer sleeve and inner sleeve.
The slow drive unit of the bitubular of above-described a kind of spring force effect is characterized in that being driven object and is connected with the double barreled spring structure that is no less than.
The large cylinder periphery of described inner sleeve has cushion rubber, and it is reliable and steady that cushion rubber rotates inner sleeve.
Of the present utility model simple in structure, cost is low, and it is steadily slow to drive object.

Among the figure: the roundlet tube 5 of inner sleeve 1, cushion rubber 2, torsion spring 3, outer sleeve 4, inner sleeve, the large cylinder 6 of inner sleeve, groove 7, inner sleeve spring groove 8, flat axle 9, circular shaft 10, the large cylinder 11 of outer sleeve, the roundlet tube 12 of outer sleeve, outer sleeve spring groove 13, hole 14, cantilever 15.
Embodiment
Now the utility model is described with an embodiment.Fig. 1-6 has shown a kind of structure of the slow drive unit of the bitubular of spring force effect, it is by inner sleeve 1, outer sleeve 4 and torsion spring 3 are formed, outer sleeve 4 (Fig. 4,5) structure is size two cylinders (11 at same axis that a Closed End is arranged, 12), the outer surface of outer sleeve closed end has cantilever 15, screw is fixed cantilever by hole 14, inner sleeve 1 (Fig. 3,4) structure also is size two cylinders (5 at same axis that a closed end is arranged, 6), roundlet tube 5 diameters of inner sleeve are slightly smaller than the little drum diameter 12 of outer sleeve, but be a bit larger tham torsion spring 3 diameters, and large cylinder 6 diameters of inner sleeve are a bit larger tham roundlet tube 12 diameters of outer sleeve, and less than large cylinder 11 diameters of outer sleeve, the big or small cylinder of outer sleeve and inner sleeve is overlapping mutually, there is axle 10 exterior edge face of inner sleeve closed end, axle 10 can be installed on the axle bed, axle has plane 9 on 10 and is driven object and is connected, torsion spring 3 is fixed on the spring groove (8 between the interior edge face of roundlet tube 5 closed ends of the roundlet tube 12 of outer sleeve and inner sleeve, 13) in, in order to make inner sleeve stability of rotation under the rotating force effect of torsion spring, inner sleeve the large cylinder outer surface have cushion rubber 2 to be installed in groove 7.
When the double barreled spring structure is installed, plane 9 is connected is driven on the object, this moment, object should be in tightening state, therefore, inner sleeve can not arbitrarily rotate, then, after making torsion spring change certain angle by outer sleeve, again with screw by the hole 4 fixed jacket tubes on the cantilever 14.At this moment, the double barreled spring structure be driven object and be in motionless state, when discharging by the object of fastening, the rotation elastic force of torsion spring makes by inner sleeve and rotates, and drives plane 9 on the axle and push open and be driven object, just as opening the door.
