Abstract
Name of the present invention is called to have one degree of freedom, rotatable seesaw, with realize traditional seesaw move up and down and the revolution of carrousel is integrated as object.Utilize double rocker mechanism to realize moving up and down of seesaw, the connecting rod in double rocker mechanism is that driving link realizes complete cycle revolution, for seesaw provides power by pedal applying driving force; The rotation of seesaw is ratchet by being fixed on base and is completed by the R-2SSR-R spatial linkage ratchet to seesaw.Employ thrust ball bearing between the column of seesaw and base, make seesaw main body keep rotating steadily, decrease the friction and wear between column and base simultaneously.Overall structure is ingenious, compact, motion is flexible, achieves the innovation of mechanism.Advantage: it is little that this seesaw takes up an area space, structure is simple, and cost is low, does not need external power supply, energy-conserving and environment-protective.Being applicable to very much five to ten two years old entertainment for childrens to play, is the good toy of children's amusement and recreation.
Description
Technical field
The present invention relates to entertainment for children machinery, be that one has one degree of freedom, can realize moving up and down and the pivotal revolvable seesaw of complete cycle simultaneously, be made up of double rocker mechanism, ratchet mechanism and R-2SSR-R spatial linkage.
Background technology
Along with the continuous progress of modern society, all kinds of recreational facilities of children-oriented, educational toy are multifarious, the enjoyment making present children be not content with traditional recreational facilities to bring, but more like recreational higher, game that independence is stronger; On the other hand, for Parents, then wish the exercise obtaining body and mind while child is at play.Tradition seesaw structure is simple, moves single, and carrousel complex structure, involve great expense, being suitable for place is limited to, and is therefore difficult to popularize.
Through inquiry, patent publication No. CN102228742A's, patent of invention title is Cockhorse seesaw, publication date is on November 2nd, 2011, this patent of invention includes arc-shaped base, arc-shaped base is established middle seat board, and middle seat board two ends are respectively equipped with balancing pole, the balancing pole at two ends is respectively equipped with the second seat board and the 3rd seat board, the arc surface both sides of arc-shaped base are provided with spacing stabilizing leg.Its weak point is that this invention can not realize rotating, and function singleness, interest is not strong.
Through inquiry, seesaw that have one degree of freedom, that can rotate does not have patent application.
Summary of the invention
The present invention in order to solve the function singleness of common traditional seesaw and increase children's game and interactive, provide a kind of have one degree of freedom, can realize moving up and down and the pivotal Novel rotary seesaw of complete cycle simultaneously.
The present invention is in order to realize above-mentioned object, the technical scheme adopted is: seesaw is by double rocker mechanism, ratchet mechanism and R-2SSR-R spatial linkage composition, realize seesaw by double rocker mechanism to move up and down, ratchet mechanism take ratchet as the revolution of frame ratchet complete cycle, by R-2SSR-R spatial linkage, the complete cycle of ratchet is converted to the complete cycle revolution of seesaw.
Described double rocker mechanism comprises column, seesaw, rocking bar and connecting rod.Seesaw two ends are provided with seat board, and seat board front end is provided with handrail, and seesaw lower end part is provided with two symmetrical connecting rods and is connected with column.Described symmetrical connecting rod is provided with pedal, is connected by two revolute pairs at seesaw lower end part.
Described ratchet mechanism comprises ratchet and pawl.Ratchet is fixedly connected with base becomes frame, and ratchet is connected on annulus by revolute pair, and annulus can turn round around column complete cycle.
Described R-2SSR-R spatial linkage comprises seesaw, space connecting-rod, ratchet and column, and connecting rod is connected with ratchet, and column and ratchet are formed by thrust bearing and coordinate.When seesaw is lifted up up and down, promote ratchet by space connecting-rod and rotate around column, column and ratchet are formed by thrust bearing and coordinate, and because ratchet maintains static, then reaction force promotion seesaw turns round in thrust bearing around column.Opposite side forms of motion is identical, and when seesaw is lifted up up and down, both sides alternating action, seesaw can complete cycle revolution.
Accompanying drawing explanation
Accompanying drawing 1 is the main body mechanism kinematic sketch of seesaw.
Accompanying drawing 2 is for realizing the pivotal kinematic sketch of mechanism of seesaw complete cycle.
Accompanying drawing 3 is the overall setup kinematic sketch of seesaw.
In figure, 1. connecting rod a, 2. seesaw, 3. connecting rod b, 4. rocking bar a, 5. rocking bar b, 6. column, 7. ratchet, 8. space connecting-rod a, 9. space connecting-rod b, 10. ratchet a, 11. ratchet b.
Detailed description of the invention
In accompanying drawing 1, in double rocker mechanism with connecting rod a (1) and connecting rod b (2) for driving link, complete cycle turns round, and drives seesaw (2) and rocking bar a (4) and rocking bar b (5) reciprocally swinging, realizes moving up and down of seesaw (2).In this mechanism, pass through smoothly when seesaw (2) can be made to be in high-low limit position, overcome the dead-centre position in double rocker mechanism.
In accompanying drawing 2, when seesaw (2) is lifted up up and down, promote ratchet a (10) and ratchet b (11) respectively by space connecting-rod a (8) and space connecting-rod b (9) and rotate around column (6); Because ratchet (7) and base are fixedly connected motionless, column (6) and ratchet (7) are formed by thrust bearing and coordinate, then reaction force promotion seesaw (2) of ratchet (7) to ratchet a (10) and ratchet b (11) turns round around column (6) complete cycle.Coordinated with R-2SSR-R spatial linkage by ratchet mechanism, when seesaw is lifted up up and down, both sides alternating action, seesaw can complete cycle revolution.
In accompanying drawing 3, driving link is bar AG, does complete cycle revolution, and for system provides power, finally realizing can complete cycle revolution while seesaw moves up and down.
The present invention passes through double rocker mechanism dexterously, ratchet mechanism coordinates with R-2SSR-R spatial linkage, is that driving link provides power with connecting rod, and ratchet, around pawl wheel, makes seesaw can turn round by complete cycle while lifting up up and down.Employ thrust ball bearing between the column of seesaw and base, make seesaw main body keep rotating steadily, decrease the friction and wear between column and base simultaneously.The present invention can a people be used alone, and also can two people use simultaneously, independence and recreationally greatly to strengthen; There is provided power by pedal when being at play, can realize moving up and down and rotating, break away from the constraint of power supply; Mechanism's exquisiteness is compact, and rationally simply, cost of manufacture is low, can extensive use.
