Abstract
The utility model discloses a gravity weight lever of a force-velocity converter and belongs to the field of toys. Levers are formed into a toy for children to play. An unequal arm lever A, an unequal arm lever B and an unequal arm lever C are respectively supported by three fulcrums, and the resisting arm end of the lever A 3 and the power arm end of the lever B 2 are connected by using a flexible wire 5. The resisting arm end of the lever B 2 and the power arm end of the lever C 4 are connected by using the flexible wire 5. The remaining disconnected power arm ends are connected with a gravity weight 7 by using the flexible wire 5, and the remaining disconnected resisting arm ends are connected with a gravity weight 6 by using the flexible wire 5. By adding and decreasing gravity weights on the gravity weight 7 and the gravity weight 6, the children can play.
Description
Technical field
A kind of heavily stone roller lever of power speed converter belongs to the toy field.
Background technology
A lever is common, can make children obtain the knowledge of lever in being at play.But in current science, we have found power speed converter again, and it illustrates the relation of power and speed.The knowledge that people can obtain to be correlated with in appreciation is enjoied.Lever power speed converter (method of application number 2010105187336 power speed converter and animal generating) is made toy, allow children play, appreciate the marvellous of it, a lot of toys can not be compared.
Summary of the invention
Present technique provides a kind of heavily stone roller lever of power speed converter, and it can make lever under the effect of gravity, and the lever two ends are when plus-minus gravity, and an end moves a little distance, and the other end but moves a very long segment distance; One end transfer point point distance but will be taken very big gravity, could start the other end and move.Being convenient to children adds and subtracts weight steelyard weight and plays.
This utility model is such: three fulcrums 1 are arranged, support three multiplying levers of ABC respectively, the resistance arm end of A bar 3 is connected with flexible cord 5 with the power arm end of B bar 2.The resistance arm end of B bar 2 is connected with flexible cord 5 with the power arm end of C bar 4.The power arm end of last remaining A bar 3 is not connected with the resistance arm end of C bar 4.The remaining power arm end that does not connect connects one with flexible cord 5 and heavily cuts or polish jade with an emery wheel 7, and the remaining resistance arm end that does not connect connects one with flexible cord 5 and heavily cuts or polish jade with an emery wheel 6.Heavily stone roller can have a plurality of.There is hook at each two ends up and down of heavily cutting or polish jade with an emery wheel, stone roller with cut or polish jade with an emery wheel between hook mutually.
Some distances because the resistance arm of a multiplying lever rises, the power arm end very long segment distance that will descend, when three or many multiplying levers connected according to the order of sequence, the resistance arm end that connects with flexible cord equated with the distance of power arm end when mobile, therefore, make the resistance arm end that does not connect move some distances, every through a multiplying lever, just be exaggerated once, when arriving the power arm end that does not connect, will be put very greatly.Vice versa.When playing, can add and subtract one or more heavy stone rollers at the heavily stone roller of the resistance arm that does not connect, the resistance arm end is sunk.Also can the resistance arm end be risen at the one or more heavy stone rollers of heavily stone roller plus-minus of the power arm end that does not connect, the power arm end sinks.{ annotate: the connection according to the order of sequence of above-mentioned many multiplying levers is exactly lever power speed converter.In lever power speed converter, the resistance arm end of Lian Jieing does not move simultaneously with the power arm end that is not connected, and finishes motion simultaneously.Therefore, two ends used time before and after motion equates to be T
1=T
2After deliberation, their formula is: under the poised state, the power of the power arm end of Lian Jieing and speed is not long-pending, the power of the resistance arm end that equals not connect and the long-pending F of being of speed
1V
1=F
2V
2In the lever group, the power effect of the startup lever group minimum that applies of the power arm end of Lian Jieing not is that in-fighting is F
Greatly=G η (1/n+1/n
2+ 1/n
3), the power effect of the minimum of the startup lever group of the resistance arm end of Lian Jieing not is that in-fighting is F
Little=G η (1+n
1+ n
2).The content that braces contains is plucked the works with me }.Present patent application is toy, and this section is only for referencial use.
Owing to adopt above-mentioned design, make the gravity lever of capable fast converter, can add the loss of weight stone roller, the two ends that the lever group is not connected can dipping and heaving.And the resistance arm end transfer point point distance of Lian Jieing not, not the power arm end of Lian Jieing will move a very long end distance from.
Description of drawings
Fig. 1 is the heavily stone roller lever full figure of power speed converter.
The specific embodiment
In 1 figure, three fulcrums 1 support three multiplying levers of ABC respectively, and the resistance arm end of A bar 3 is connected with flexible cord 5 with the power arm end of B bar 2.The resistance arm end of B bar 2 is connected with flexible cord 5 with the power arm end of C bar 4.The power arm end of last remaining A bar 3 is not connected with the resistance arm end of C bar 4.The remaining power arm end that does not connect connects one with flexible cord 5 and heavily cuts or polish jade with an emery wheel 7, and the remaining resistance arm end that does not connect connects one with flexible cord 5 and heavily cuts or polish jade with an emery wheel 6.Heavily stone roller can have a plurality of.There is hook at each two ends up and down of heavily cutting or polish jade with an emery wheel, stone roller with cut or polish jade with an emery wheel between hook mutually.
Or similar techniques, all row in the protection of this patent contained identical with this patent.
