Frame, plate body connection rotating shaft, the left and right ends of plate body form premultiplication position and the right side and multiply position respectively, and the seesaw of prior art is in the presence of as follows
Shortcoming：The velocity of rotation of plate body is too fast, and this can bring two problems, one, the velocity of rotation of plate body it is too fast, can be produced when plate body lands
Raw very big impulsive force, this can make user not feel well, two, the velocity of rotation of plate body it is too fast, user is in a vacant state
Time will be reduced, and user can think that seesaw lacks enjoyment, based on this, it is necessary to a kind of seesaw is provided, it is this to lift up
The velocity of rotation of the plate body of seesaw will not be too fast.
Utility model content
The technical problems to be solved in the utility model is the present situation for prior art, there is provided a kind of simple and reasonable
Seesaw, and the velocity of rotation of the plate body of this seesaw will not be too fast.
The technical scheme that the utility model solves the above problems is：A kind of seesaw, including plate body, support, rotating shaft；Rotating shaft
Support is rotatablely connected, plate body connection rotating shaft, the left and right ends of plate body form premultiplication position respectively and the right side multiplies position；Also include the first tooth
Wheel, second gear, runner, steel ring, slide rail, sliding block, extension spring；First gear connection rotating shaft, second gear are rotatably connected on support
On, first gear intercouples with second gear, and the radius of first gear is more than the radius of second gear；Runner connects the second tooth
Wheel, the radius of runner are more than the radius of second gear；Slide rail head end is connected to the wheel of runner in the heart, and such slide rail can be with runner
Rotate together；Steel ring connecting bracket, steel ring are located at the avris of runner, when slide rail rotates together with runner, the tail end of slide rail
Slide in the inner side of steel ring；Sliding block is slidably connected on slide rail；Extension spring one end connecting sliding rail head end, other end connection sliding block.This
When in use, with the rotation of plate body, rotating shaft also gyrates the seesaw of utility model, and rotating shaft drives first gear, the
One gear drive second gear, second gear drive runner, driven by rotating wheel slide rail rotate, under the influence of centrifugal force, sliding block to
Slide rail tail end direction is moved, when pulling force just offsets centrifugal force caused by extension spring, sliding block ability stop motion, if the rotation of plate body
Speed is not that quickly, sliding block can't touch steel ring, is accelerated with the velocity of rotation of plate body, the centrifugal force that sliding block is subject to is also corresponding
Increase, when the velocity of rotation of plate body it is big to a certain extent when, sliding block can touch steel ring, and frictional force is produced between sliding block and steel ring,
This frictional force can suppress plate body and further speed up, so that the velocity of rotation of plate body is controlled in certain scope.
Compared with prior art, the utility model is a kind of seesaw, including plate body, support, rotating shaft；Axis of rotation connects
Support, plate body connection rotating shaft, the left and right ends of plate body form premultiplication position respectively and the right side multiplies position；Also include first gear, the second tooth
Wheel, runner, steel ring, slide rail, sliding block, extension spring；First gear connection rotating shaft, second gear are rotatably connected on support, the first tooth
Wheel intercouples with second gear, and the radius of first gear is more than the radius of second gear；Runner connects second gear, runner
Radius is more than the radius of second gear；Slide rail head end is connected to the wheel of runner in the heart, and such slide rail can rotate together with runner；
Steel ring connecting bracket, steel ring are located at the avris of runner, and when slide rail rotates together with runner, the tail end of slide rail is slided in steel ring
Inner side；Sliding block is slidably connected on slide rail；Extension spring one end connecting sliding rail head end, other end connection sliding block.The utility model has
Have the advantage that：Simple and reasonable, the velocity of rotation of the plate body of seesaw will not be too fast.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model embodiment 1.
Embodiment
The utility model is described in further detail with reference to embodiments：
Embodiment 1
A kind of seesaw, including plate body 1, support 2, rotating shaft 3；Rotating shaft 3 is rotatablely connected support 2, the connection rotating shaft 3 of plate body 1, plate
The left and right ends of body 1 form premultiplication position 1A respectively and the right side multiplies a 1B；Also include first gear D1, second gear D2, runner D3, steel
Enclose D5, slide rail D6, sliding block D7, extension spring D8；First gear D1 connection rotating shafts 3, second gear D2 is rotatably connected on support 2, the
One gear D 1 intercouples with second gear D2, and first gear D1 radius is more than second gear D2 radius；Runner D3 connections
Second gear D2, runner D3 radius are more than second gear D2 radius；Slide rail D6 head ends are connected to runner D3 core wheel D31
On, such slide rail D6 can be rotated together with runner D3；Steel ring D5 connecting brackets 2, steel ring D5 are located at runner D3 avris, work as cunning
Rail D6 with runner D3 rotate together when, slide rail D6 tail end is slided in steel ring D5 inner side；Sliding block D7 is slidably connected at slide rail
On D6；Extension spring D8 one end connecting sliding rail D6 head ends, other end connection sliding block D7.
What the utility model was realized in：Seesaw of the present utility model when in use, with the rotation of plate body 1, turns
Axle 3 also gyrates, and rotating shaft 3 drives first gear D1, first gear D1 to drive second gear D2, second gear D2 band turns
D3 is taken turns, runner D3 drives slide rail D6 to rotate, and under the influence of centrifugal force, sliding block D7 moves to slide rail D6 tail ends direction, works as extension spring
When pulling force caused by D8 just offsets centrifugal force, sliding block D7 ability stop motions, if the velocity of rotation of plate body 1 is not quickly, sliding block
D7 can't touch steel ring D5, accelerate with the velocity of rotation of plate body 1, the centrifugal force that sliding block D7 is subject to also accordingly increases, and works as plate
The velocity of rotation of body 1 it is big to a certain extent when, sliding block D7 can touch steel ring D5, and frictional force is produced between sliding block D7 and steel ring D5,
This frictional force can suppress plate body 1 and further speed up, so that the velocity of rotation of plate body 1 is controlled in certain scope.
