The specific embodiment
Embodiment 1: Fig. 1 shows basic structure of the present utility model.One end of a main lever 1 is connected with 5 at fulcrum, longitudinally is provided with chute 6 on main lever 1 body.One end of an auxiliary lever 2 also is connected with 5.1 at fulcrum, and the other end of this auxiliary lever 2 cooperates with the chute 6 of main lever 1 by the roller 4 that is arranged on its end, and promptly roller 4 can be reciprocating along the length direction of chute 6, thereby drives auxiliary lever 2 actions.Connect a dowel bar 3 at the middle part of auxiliary lever 2 by live axle 7, the other end of this dowel bar 3 directly is connected with driven equipment such as jack or wheel.
When depressing main lever 1, roller 4 drives auxiliary lever 2 along chute 6 when move in oblique below be that also move to oblique below in the center of circle with fulcrum 5.1, makes the continuous mechanical action of dowel bar 3 direct drives that is connected on the auxiliary lever 2 simultaneously.
Embodiment 2: Fig. 2, Fig. 3 are expansion structures of basic structure shown in Figure 1.Except that main lever 1 has chute 6, equally also be provided with chute 9 on the auxiliary lever 2, and the roller 8 of dowel bar 3 ends is along vertical crank motion of chute 9, the other end of dowel bar 3 is connected with 5.2 at fulcrum, also form a lever construction, another dowel bar 10 is connected the middle part of this dowel bar 3 again by live axle 7, the other end of dowel bar 10 directly links to each other with the machinery that is driven, and forms three grades of laborsaving levers.
By that analogy, on with the basis of basic structure shown in Figure 1, can increase to level Four or more multistage lever according to the structure connection mode of Fig. 2, Fig. 3, every grade than dowel bar of upper class increase, a last dowel bar directly links to each other with the machinery that is driven, the labour-saving acts on to play more, and every grade course of action is all identical with embodiment 1 described process.
Embodiment 3: Fig. 4 is to be another embodiment of basic structure with Fig. 1, the bottom of main lever 1 and auxiliary lever 2 is arcuate structure, the chute 6 that is positioned at equally on the main lever 1 also is arc, the lower end of major and minor lever 1,2 is connected with separately 5,5.1 at fulcrum respectively, and a dowel bar 3 is connected on the auxiliary lever 2 by live axle.
Course of action and embodiment 1 are described identical, and just the roller 4 of auxiliary lever 2 terminations is to do the camber line crank motion in an arc chute 6.
Embodiment 4: Fig. 5 is a kind of expansion on Fig. 4 architecture basics, wherein auxiliary lever 2 bottoms also are provided with arc chute 6.1, the end that another root bottom is provided with the auxiliary lever 2.1 of arc chute 6.2 cooperates with chute 6.1 by roller 4, and the other end is connected with corresponding 5.2 at fulcrum.Also have an auxiliary lever 2.2 to cooperate in chute 6.2 by the roller 4 of one end, and the other end is connected with corresponding 5.3 at fulcrum, one and driving device bonded assembly dowel bar 3 are connected on this auxiliary lever 2.2 by live axle 7, form three grades of lever constructions.In the course of action, the roller 4 of each grade auxiliary lever 2,2.1,2.2 terminations is all done movement in a curve in the chute 6,6.1,6.2 of upper class, and driving each grade auxiliary lever 2,2.1,2.2 is center of circle action with separately fulcrum 5.1,5.2,5.3 respectively, is connected the dowel bar 3 direct drive corresponding device thereof works done on last root auxiliary lever 2.2.
By that analogy, above-mentioned structure also can expand to four or multi-grade lever more, to play labour-saving effect more.
Fig. 6, Fig. 7 are the structures that is connected every grade of auxiliary lever termination roller 4, and described this roller 4 can be the bearing that is connected the auxiliary lever termination by axis 11, also can be the circular wheel that directly is fixed on the axis 11.Roller 4 both can be positioned at chute, also can be positioned at outside the real core main lever 1 and auxiliary lever 2 of not establishing chute 6.Roller 4 and major and minor lever both cooperated friction of rolling, also cliding friction, its fit system are not limited to Fig. 6, form shown in Figure 7.
Above-described various version can be used for that a lot of needs adopt lever constructions and the labour-saving needs pressure maybe to need to hold up the equipment or the device of weight or drive configuration, reaches the final purpose of more laborsaving, reduction consumption of power, energy savings by multi-grade lever.
