Description
Technical field
The utility model relates to glasses field of measuring technique, especially ear pitch measuring ruler.
Background technique
Spectacle frame is the important component of glasses, primarily serves the effect of support spectacle lens.In reality, people are being matched
When spectacle frame, often only focuses on material, weight, toughness, the aesthetics etc. of mirror holder, but ignore and wearing comfort is even regarded
Power influences bigger mirror holder parameter, such as the distance between the length of temple, the curvature of footmuff, Jing Quan, the length etc. of Jing Quan.
Even if having paid attention to these parameters when matching mirror holder, it is also very inconvenient that measuring appliance gets up, and is measured using traditional artificial ruler, not only
Error is larger, and time-consuming and laborious.
Therefore, it is necessary to propose ear pitch measuring ruler in response to the above problems.
Utility model content
The utility model aim is to overcome deficiency in the prior art, provides ear pitch measuring ruler.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions:
Ear pitch measuring ruler, including the first measurement plate and the second measurement plate, one end of first measurement plate are surveyed with second
One end of template is hinged, and one end lower part of first measurement plate is formed with arc plate, and the arc plate is provided with curved scale ruler, institute
The other end for stating the first measurement plate is provided with the first crotch tip, and the other end of second measurement plate is provided with the second crotch point
End, it is right in curved scale ruler institute that the spacing dimension between first crotch tip and the second crotch tip is equal to the second measurement plate
The size answered.
Preferably, the meter full scale of the curved scale ruler is 0-200, and the scale unit of the curved scale ruler is 5mm.
Preferably, first measurement plate and the second measurement plate hinged place are provided with pin shaft, and tune is provided on the pin shaft
Save knob.
Preferably, a side of second measurement plate is additionally provided with the scale marker for assigned scale.
Preferably, the measurement tolerance of the curved scale ruler is +/- 0.5mm.
Preferably, the length of first measurement plate and the second measurement plate is 256mm, the both ends of first measurement plate
Width is 116.9mm between point.
The utility model is the utility model has the advantages that one end of first measurement plate of the utility model and one end of the second measurement plate are cut with scissors
It connects, one end lower part of the first measurement plate is formed with arc plate, and arc plate is provided with curved scale ruler, the first measurement plate and the second measurement plate
Hinged place is provided with pin shaft, and adjusting knob is provided on pin shaft, and a side of the second measurement plate is additionally provided with for assigned scale
Scale marker.
Make furtherly below with reference to technical effect of the attached drawing to the design of the utility model, specific structure and generation
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
