Description
Technical field
The utility model relates to spanner field, particularly a kind of Spanner with aid.
Background technology
The Spanner with aid structure of current use as shown in Figure 1, comprise mount pad 1, turning cylinder 2, gear 3 and pivotal plate 4, one end of turning cylinder 2 is fixedly connected with pivotal plate 4 with the through hole in the middle of pivotal plate 4 through the through hole in the middle of mount pad 1 successively, the other end is connected by unilateral bearing 10 with gear 3, when using handle 11 to rotate pivotal plate 4, pivotal plate 4 can drive turning cylinder 2 to rotate, and then driven gear 3 rotates, to realize the rotation of other frame for movement be connected with gear 3, utilize lever principle, more laborsaving.
The angle that known above-mentioned handle 11 rotates equals the angle that turning cylinder 2 and gear 3 rotate, and if need the angle of rotating very little time, be manually difficult to accomplish that high accuracy controls.
Utility model content
utility model object:for problems of the prior art, the utility model provides a kind of Spanner with aid, and can carry out the rotation of smaller angle manually to turning cylinder, precision is relatively high, is applicable to fine setting.
technical scheme:the utility model provides a kind of Spanner with aid, mainly comprise mount pad, turning cylinder, gear, pivotal plate and connecting plate, one end of described turning cylinder is fixedly connected with described connecting plate through the through hole in the middle of mounting seat, the through hole of pivotal plate centre and the through hole of connecting plate one end successively, and the other end is connected by unilateral bearing with gear; Described Spanner with aid also comprises the slide block of intercalation in described pivotal plate edge groove, and the straight pin by being fixed on the described connecting plate other end between described connecting plate and this slide block is rotationally connected; Be rotationally connected by the eccentric pin be fixed in this pivotal plate between described pivotal plate and mount pad.
Preferably, the through hole in the middle of described pivotal plate is fan-shaped pylone.
Preferably, described turning cylinder is fixedly connected with flat key by jump ring with between connecting plate.
Preferably, described turning cylinder is connected with being screwed between connecting plate.
operation principle and beneficial effect:can take eccentric pin as axis of rotation when pivotal plate is rotated under external force, the one end of the connecting plate that the rotation drive of pivotal plate is connected with slide block take eccentric pin as axis of rotation, and then the other end driving the connecting plate be connected with turning cylinder take turning cylinder as axis of rotation, the rotation of connecting plate drives turning cylinder with himself for axis of rotation, final drive is fixed on the pinion rotation on turning cylinder, realizes the rotation to the exterior mechanical structure be connected with gear; It is worth mentioning that, because the length of connecting rod is fixed, so while the one end of the connecting plate be connected with slide block is axis of rotation with eccentric pin, slide block can move forward and backward in the edge groove of pivotal plate, to adapt to the rotation of pivotal plate and then to realize the rotation of connecting plate.According to above-mentioned operation principle: the angle that eccentric pin rotates must be greater than turning cylinder rotational angle, so, compared with prior art, the utility model can be used for finely tuning, namely the angle of actual manual rotation is larger, but the rotational angle of practical function in outside frame for movement is less, is manually easier to control accuracy.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model preferred embodiment is described in detail.
As as described in Fig. 2 ~ 4, Spanner with aid in present embodiment is primarily of mount pad 1, turning cylinder 2, gear 3, pivotal plate 4, connecting plate 5 and slide block 6 form, one end of turning cylinder 2 is fixedly connected with gear 3 by unilateral bearing 10, with ensure gear 3 can only under the drive of turning cylinder 2 one-directional rotation, the other end of turning cylinder 2 is first through the manhole in the middle of mount pad 1, and then through the fan-shaped pylone in the middle of pivotal plate 4, eventually pass through after being coordinated with flat key 12 by jump ring 9 between the middle manhole of connecting plate 5 and one end of connecting plate 5 and be fixedly connected with (also directly can be screwed and be connected), be rotationally connected by eccentric pin 8 between pivotal plate 4 and mount pad 1, this eccentric pin 8 is fixed on the non-central location of pivotal plate 4, the edge of pivotal plate 4 has also offered groove, intercalation slide block 6 in groove, this slide block 6 can in above-mentioned groove slide anteroposterior, be rotationally connected by the straight pin 7 be fixed on connecting plate 5 between the other end of connecting plate 5 and slide block 6, namely slide block 6 also can with straight pin 7 for axis of rotation, the sidewall of pivotal plate 4 in addition also has and can insert outer handle 11 to facilitate the jack rotating pivotal plate 4.
(in figure, solid line is the position of each parts before rotating as shown in Figure 5, dotted line is the position of each parts after rotating), when outer handle 11 insert jack rotate clockwise pivotal plate 4 time, if pivotal plate 4 with eccentric pin 8 for rotating shaft rotates clockwise, the rotation of pivotal plate 4 can be with movable slider 6 one aspect with eccentric pin 8 for rotating shaft rotates clockwise, on the other hand with straight pin 7 for rotating shaft rotates clockwise, because one end of connecting plate 5 and slide block 6 are rotationally connected, the other end is fixedly connected with turning cylinder 2, when slide block 6 rotates clockwise with the rotation of pivotal plate 4, one end of connecting plate 5 one side will be driven with eccentric pin 8 for rotating shaft rotates clockwise, another facilitates with straight pin 7 as axis of rotation, the distance a arrived between turning cylinder 2 due to length b and the eccentric pin 8 of connecting plate 5 is constant, can rotate so slide block 6 only slides backward guarantee pivotal plate 4 in the edge groove of pivotal plate 4, and the rotation of connecting plate 5 one end can drive the one end be fixedly connected with turning cylinder 2 also to rotate, thus drive turning cylinder 2 to rotate clockwise together, rotating clockwise of the gear 3 that final realization is connected with turning cylinder 2 by unilateral bearing 10.As can be seen from Figure 5, during eccentric pin 8 rotational angle A (pivotal plate rotational angle A), turning cylinder 2 have rotated angle B, as can be seen from the figure, angle A must be greater than angle B, that is when needs rotate smaller angle to turning cylinder 2, can realize by rotating pivotal plate 4 larger angle manually, this makes it possible to the error reducing artificial adjustment turning cylinder 2 rotational angle, be applicable to fine setting.
Above-mentioned embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the utility model Spirit Essence or modification, all should be encompassed within protection domain of the present utility model.
