Embodiment four
See accompanying drawing 4, the structural representation of embodiment four of the present utility model.
Also including the push rod 7 that top board the second end 12 is provided with, push rod 7 is curved, the half of push rod 7 place arc
Footpath is equal to the distance of top board the second end 12 to top board the first end 11, one end of push rod 7 and top board the second end 12
Fixing connection, the other end of push rod 7 is used for applying elastic force to elastic 4,
Also including sleeve 8, sleeve 8 hollow, sleeve 8 bends to arc, the radius of sleeve 8 place arc
Equal to the radius of push rod 7 place arc, push rod 7 extends to sleeve 8 hollow space, and elastic 4 is located at sleeve
8 is internal, and when top board 1 rotates to sleeve 8 direction, push rod 7 gos deep into sleeve 8 and applies bullet to elastic 4
Power.
It is preferable that, push rod 7 place plane, and the coincidence of top board the second end 12 Plane of rotation.In other words:
Plane determined by push rod 7, and the coincidence of top board the second end 12 Plane of rotation.Why with determining two words？
Because push rod 7 is an arc, arc may determine that a plane.
Device described in embodiment one, two, three, all there is a problem in that and reads power from force transducer 2
Numerical value is it is then determined that deformation quantity, and the deformation quantity error obtained is bigger.
The most such？Reason is: the direction that top board the second end 12 applies elastic force is not perpendicular to power sensing
Device probe 21, or can not be always vertical, because top board 1 is to rotate.And force transducer probe 21 impression
The size of power is the most directive, say, that the elastic force that force transducer probe 21 detects is vertical spy
The pressure in head contact surface direction.
How that solves this technical problem？The technical scheme that embodiment four is given, it is simply that solve this
Individual technical problem, what embodiment four can reach have the technical effect that top board 1 is rotating when, (certainly,
It is not to turn-take continuously as motor, but says and turn over certain radian), no matter rotate to which angle,
The power that force transducer probe 21 is experienced all is perpendicular to probe contacts face.
Somewhat understanding that the people of a mechanical knowledge both knows about, power is vector, can decompose, if measuring the big of elastic force
Little it is necessary to allow elastic force be perpendicular to force transducer probe 21 contact surface, this is basic general knowledge.We are with 10
The power of newton is perpendicular to electronic scale, and electronic scale shows 10 newton, if with 10 newton, be not orthogonal to electronics
The power of scale contact surface acts on electronic scale, and the power that electronic scale shows is not the most 10 newton.Certainly, market is sold
The electronic scale of dish makes reading be converted to kilogram by internal circuit.
How embodiment four reaches such technique effect？Look at: push rod 7 second end is near elastic
The process of thing 4, it is simply that push rod 7 is to the internal process extended of sleeve 8, and the radius of push rod 7 place arc is equal to
Top board the second end 12 is equal to push rod 7 place to the distance of top board the first end 11, the radius of sleeve 8 place arc
The radius of arc, then, push rod 7 just can put in sleeve 8, exit, thus elasticity of compression thing 4,
Such as spring, or as a example by spring, continuing with seeing: spring not only can change length axially along,
Namely extend, compress, it is also possible to be perpendicular to its axial bending.In embodiment four, elastic 4 can be accomplished
(such as spring) is always to the elastic force of force transducer probe 21 applying vertical direction.In other words, elastic 4 is hung down
Directly in force transducer probe 21, in other words, elastic 4 force direction is perpendicular to force transducer probe 21, this
It is most basic general knowledge.
Those skilled in the art are it is to be understood that sleeve 8 needs the lift area certain to push rod 7, otherwise,
It is internal that push rod 7 just intends to stretch into sleeve 8, is just blocked by sleeve 8.
Those skilled in the art it is to be understood that should be the most smooth in sleeve 8, allow elastic 4 (ratio
Such as spring) axially along by too many resistance.
Those skilled in the art, can be at sleeve 8 it is to be understood that in order to prevent push rod 7 from coming off from sleeve 8
Arranging a baffle plate having opening near the opening of top board the second end 12, top board 1 is stretching into that of sleeve 8
End arranges one for preventing the card from baffle plate abjection.
Further:
The center of circle of push rod 7 place arc and push rod 7 first end overlap.Why this technical characteristic is not must
Want technical characteristic？Because by some simple machinerys, it is possible to be converted to: push rod 7 place arc
The center of circle and push rod 7 first end misaligned.So, the center of circle of push rod 7 place arc and push rod 7 first end weight
Close, not necessarily technical characteristic.
The center of circle of sleeve 8 place arc and push rod 7 first end overlap.Not necessarily technical characteristic, reason is same
On.
