Specific implementation mode
Vehicle in a kind of Purely mechanical meter, is shown in Fig. 1 to Fig. 4, vehicle includes transfer bar mechanism 1, roller mechanism 2, timbering machine in the meter
Structure 3, measurement ruler mechanism 4 and clamp system 5, the roller mechanism include axis 22, and 23 He of left wheel is respectively equipped in axis left and right ends
Right idler wheel 21 is equipped with bearing 25 in the middle part of axis, and bearing holder (housing, cover) 13 is equipped on the outside of bearing, and left tooth is equipped between left wheel and bearing
Wheel 24 is equipped with right gear 26 between right idler wheel and bearing；Transfer bar mechanism includes handle 11 and stabilizer blade 12, handle and bearing holder (housing, cover) 13
Connection；Stabilizer blade is arranged in handle lower part.Bracket institution includes horizontal axis 39 and vertical pivot 38, and vertical pivot 38 passes through casing 14 and bearing holder (housing, cover) 13
Connection, hanging scroll 32 is equipped at the both ends of horizontal axis 39, the gear 61 that can slide up and down is equipped in hanging scroll lower end, in the correspondence two of horizontal axis
Side is equipped with pointer 36.Measurement ruler mechanism includes two-sided measurement ruler 41 with a scale, in measurement ruler, scale size and measurement ruler movement speed phase
Adaptation.The measurement ruler is wound on hanging scroll upper end；Clamp system includes connecting shaft 53, guide post 57, tension spring 58 and pressing plate 54, and guide post is logical
It crosses guide sleeve to be connected in connecting shaft, tension spring is sleeved on guide post, and the pressing plate for fixing measurement ruler is connect with guide post, connecting shaft installation
On the hanging scroll at both ends.Pressing plate is connect by hinge with connecting plate 56, and connecting plate is connect with guide post, is connect with connecting plate in pressing plate
Place is equipped with tension spring 55.
It is equipped with boss 31 in hanging scroll lower end, gear is fixed on 65 lower end of sliding block, is equipped on sliding block compatible with boss
Through-hole 63, gear is connected to by sliding block on hanging scroll.It is equipped with connecting hole 35 in hanging scroll upper end, connecting shaft 53 is inserted in connecting hole
It is interior, gasket 52 is equipped in connecting shaft.Hanging scroll is installed on transverse axis by bracket bearing 33.
Range measurement principle is as follows：
When small handcart moves forward, right idler wheel 21 and left wheel 23 rotate, the left gear 24 being installed on axis 22 and the right side
Gear 26 also rotates simultaneously.Through-hole and boss cooperation, the gear 61 and right tooth that sliding block moves down and sliding block coordinates in right side sliding block 65
26 cooperation of wheel, since right gear 26 rotates trolley when driving, band moving gear 61 rotates synchronously.Since sliding block 65 and gear 61 are fixed
Connection, hanging scroll 32 and sliding block 65 are connected, and therefore, hanging scroll 32 rotates synchronously, and hanging scroll 32 is coordinated by bracket bearing 33 to be fixed
On bracket institution 3, hanging scroll 32 rotates, and measurement ruler 41 is driven to be moved to from the hanging scroll of right side on the hanging scroll of left side.According to pointer 36
Reading can read distance, and left side hanging scroll receives measurement ruler, and right side hanging scroll puts measurement ruler.Pressing plate 54 is pressed on measurement ruler outer surface, is prevented
Measurement ruler is at random.
Clamp system operation principle is as follows：
When work, pressing plate 54 is pressed respectively against on the outside of the measurement ruler of left hanging scroll and right side hanging scroll, and when hanging scroll rotates, measurement ruler is from side
Hanging scroll（Driven shaft）On be moved to other side hanging scroll（Driving shaft）On, therefore the measurement ruler outer diameter on driving shaft gradually increases, and from
Measurement ruler outer diameter on moving axis is then gradually reduced.Guide post 57 and guide sleeve 59 moving come according to the variation of measurement ruler outer diameter by tension spring 58
And change, pressing plate 54 and connecting plate 56 by tension spring 55 come control pressing plate measurement ruler pressure.Measurement ruler is prevented to be detached from hanging scroll.Due to
Measurement ruler is motion state in measurement process, by clamp system, ensures that measurement ruler is steady in measurement process, can ensure using peace
It is complete convenient.
The scale of measurement ruler is not unified constant, according to the variation of measurement ruler diameter on axis, to change its scale, purpose
It is to ensure that measurement distance is accurate.Gear can also be used bevel gear, be realized the conversion in direction with selection standard spur gear.
Driving shaft rotates, and after the measurement ruler on driven shaft is all moved on driving shaft, the sliding block on driving shaft is moved up, convex
Platform and through-hole cooperation, gear and right gear separation.The sliding block on the hanging scroll of the other side is moved down simultaneously, through-hole and boss cooperation, tooth
Wheel and left gear cooperation, active hanging scroll originally become driven hanging scroll, and staff reading will below be read from note at this time.Pass through change
The gear engagement system on both sides changes driving shaft and driven shaft, changes transmission direction, realizes that circulation reciprocating type measures.
