Description
One, technical field
The utility model relates to a kind of wheel rim internal-and external diameter survey instrument, is a kind of instrument can measuring the inside and outside diameter of wheel rim, and the internal-and external diameter being applicable to various wheel rim specification is measured.
Two, background technology
Vernier caliper is at present by the widely used survey instrument of user, but its size is limited, is also unfavorable for the measurement of some Complex Parts, causes the inside and outside footpath of the wheel rim of certain structures complexity to measure.
Three, utility model content
The utility model object is to provide a kind of wheel rim internal-and external diameter survey instrument, and its range can elongate arbitrarily, simple to operate, easy to carry.
The purpose of this utility model is achieved like this, a kind of wheel rim internal-and external diameter survey instrument, comprise: interior card A, interior card B, wild card A, wild card B are formed, interior card A and the interior B afterbody that blocks are fixed together, knob is installed, can be rotated arbitrarily by knob, wild card A is fixed on interior card A head 25 centimeters of places, knob is installed, can be rotated arbitrarily by knob, wild card B is fixed on interior card B head 25 centimeters of places, is provided with knob, can be rotated arbitrarily by knob, described knob is with locking device.
The utility model be interior card A, interior card B by knob can arbitrarily wheel measuring difference size, complex structure wheel rim part, complete the measurement to Complex Parts wheel rim.
Four, accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Description of reference numerals is as follows:
1---knob 1,2---knob, 3---knob, 4---interior card A, 5---interior card B, 6---wild card A, 7---wild card B.
Five, embodiment
Be described in further details originally novel below in conjunction with drawings and the specific embodiments:
With reference to accompanying drawing, a kind of wheel rim internal-and external diameter of the utility model survey instrument, comprise: interior card A (4), interior card B (5), wild card A (6), wild card B (7) is formed, it is characterized in that: interior card A (4) and interior B (5) afterbody that blocks are fixed together, knob (1) is installed, can be rotated arbitrarily by knob (1), wild card A (6) is fixed on interior card A (4) head 25 centimeters of places, knob (2) is installed, can be rotated arbitrarily by knob (2), wild card B (7) is fixed on interior card B (5) head 25 centimeters of places, knob (3) is installed, can be rotated arbitrarily by knob (3), described knob is with locking device.
Wheel rim inwall is close to respectively by interior card A (4), interior card B (5) when measuring internal diameter, then locked knob, take out instrument after fixing, in measuring with gage, the most advanced and sophisticated position of card A (4) and interior card B (5) draws the interior diameter of wheel rim.Wheel rim outer wall maximum point is close to respectively by the sharp pawl of wild card A (6), wild card B (7) when measuring external diameter, then locked knob, take out instrument after fixing, draw wheel rim overall diameter with gage measurement wild card A (6), wild card B (7) position, tip.
