To achieve the goals above, the concrete bouncing back instrument based on ring spring designed by the present invention, including elastic stem,
Casing is characterized in that further include connecting rod, pointer, notched ring spring, described connecting rod one end and annular elastomeric
Spring notch side is hinged, and the other end and elastic stem one end are hinged, and the elastic stem is arranged in Normal Constraint device, the connection
Bar, pointer and notched ring spring are arranged in casing, and the opening mobile for elastic stem is provided on the casing;Institute
State the limit restraint device for also setting up on casing and limiting annular spring contraction position;The pointer is directed toward ring from ring spring center
Shape spring and connecting rod hinged place, the corresponding dial of the pointer are arranged on the hollow out window of casing.
Further, the dial is circular ring shape, is parallel to ring spring, is located above ring spring, the casing
Hollow out window is the transparent sight hole for being provided with transparent cap.Convenient for observing the reading of pointer, make whole device in closed sky
In, improve precision and the service life of whole device.
It further, further include being set inside the metal framework for constraining annular SPRING METHOD OF STONE to mobile metal framework
It is equipped with the sliding slot moved radially for ring spring, guarantees that ring spring loses without strain energy of distortion.
Further, it is provided with the zeroing screw for adjusting pointer direction on the ring spring, guarantees that pointer is each
Dial zero point is all pointed to before measurement, avoids initial error.
Further, the ring spring notch side is provided with shock absorbing resilient gasket, energy loss when avoiding springing back.
Further, cooperate normal direction restraint device to be provided with axially directed piece of sliding block on the elastic stem, guarantee elastic stem
The vertical excitation measured every time.
Further, the limit restraint device includes position-limitting pin and is provided in Normal Constraint device, casing and bullet
Hit the corresponding limit pin hole of bar side wall.
The present invention has the advantages that
Using ring spring as energy storage member, curvilinear motion and linear motion are mutually converted, compared with traditional design,
Instrument axial dimension can substantially be reduced.And ring spring has hysteresis effect, can provide strength and buffer, meet narrow
It is used under bulk restrictive condition, improves the operability of instrument.

Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments:
A kind of concrete based on ring spring as Figure 1-Figure 4 designed by the present invention, that the invention patent provides
Reisilometer device, including casing 1, dial 2, ring spring 5, doubly-linked lever apparatus and Accessory Members.Casing 1 is provided with one above
A reading pointer 7 is arranged in a casing limit pin hole 4,5 plane of ring spring.
Wherein, in practical applications, ring spring 5 is circular ring shape jaggy, and notch side has shock absorbing resilient gasket 8.
Wherein, in practical applications, the doubly-linked lever apparatus includes metal link rod 11, elastic stem 12 and shaft 9.Metal connects
11 one end of bar is hinged on 5 notch side of ring spring by first rotating shaft 9, and the other end passes through the second shaft 6 and elastic stem 12 1
End is hinged.Elastic stem 12 is equipped with Normal Constraint component 14, is additionally provided on elastic stem 12 and matches with Normal Constraint component 14
The axially directed piece of sliding block 13 closed;14 side wall of Normal Constraint component is provided with limit pin hole 15.Elastic stem 12 and chassis sidewall
It is correspondingly arranged on limit pin hole, cooperation position-limitting pin realizes that the accumulation of energy to entire elastic stem limits, and pointer 7 is from ring spring 5
The heart is directed toward metal link rod end shaft 9.
Wherein, in practical applications, stating dial 2 is circular ring shape, is placed in right above ring spring 5 in parallel, 1 top of casing
Transparent sight hole 3 is set.
Wherein, in practical applications, the 5 notch other side of ring spring is fixed.Remaining position is located in metal framework 16, gold
Category frame 16, which is fixed on remaining position of casing annular spring, to be moved axially along spring, Normal Constraint.
Wherein, in practical applications, ring spring notch side is provided with the zeroing spiral shell for adjusting pointer direction
Nail.When practical application, elastic stem 12 is compressed by external force, doubly-linked lever apparatus is driven to move, ring spring 5 is shunk.To annular elastomeric
Spring 5 is contracted to required position, and limit pin hole 15 cooperates position-limitting pin to constrain elastic stem, i.e., carried out about to ring spring
