Abstract
The invention discloses a gap measuring instrument. The gap measuring instrument comprises a body. One end of the body is provided with an adjustment knob, the rear portion of the adjustment knob is provided with a fine tuning knob, a first telescopic rod is telescopically arranged at the other end of the body, a second telescopic rod is telescopically arranged on the rear portion of the first telescopic rod, the surface of the first telescopic rod is provided with a scale, and the surface of the body is provided with a scale. According to the gap measuring instrument, the body is provided with the adjustment knob for rotational control of the length of the telescopic rods by turning the telescoping of the length into the rotation of the adjustment knob for further enlarging the straight line distance, and meanwhile, the fine tuning knob is arranged on the adjustment knob to greatly improve the measurement accuracy of the gap measuring instrument.
Description
Technical field
The present invention relates to a kind of measuring instrument, or rather, is a kind of clearance meter.
Background technology
Gap be the size of the finger-hole difference that deducts the size of the axle matched on the occasion of.When hole is maximum limit of size, axle is the minimum limit of size, the hole after assembling, axle are the most loose mated condition, are called maximal clearance Xmax; When hole is the minimum limit of size, axle is maximum limit of size, the hole after assembling, axle are the tightest mated condition, are called minimum clearance Xmin.
The accuracy of instrument of the measurement clearance generally used at present is not high, cannot reach the precision of needs for some distances higher to accuracy requirement.
Summary of the invention
The present invention mainly solves the technical matters existing for prior art, thus provides the clearance meter that a kind of measuring accuracy is higher.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:
A kind of clearance meter, comprise a body, an adjusting knob is provided with in one end of described body, a vernier adjustment knob is provided with at the afterbody of described adjusting knob, be provided with one first expansion link at the other end telescopically of described body, be provided with one second expansion link at the afterbody telescopically of the first described expansion link.
As preferred embodiment of the present invention, the surface of the first described expansion link is provided with scale.
As preferred embodiment of the present invention, the surface of described body is provided with scale.
Because clearance meter of the present invention is provided with for rotating the adjusting knob controlling length of telescopic bar on body, by the flexible rotation changing into adjusting knob of length, thus be exaggerated air line distance, also on adjusting knob, be provided with vernier adjustment knob simultaneously, thus substantially increase the measuring accuracy of clearance meter.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of clearance meter of the present invention;
Fig. 2 is the perspective view of the clearance meter in Fig. 1, is now another visual angle.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The invention provides the clearance meter that a kind of measuring accuracy is higher.
As shown in Figure 1 and Figure 2, a kind of clearance meter 1, comprise a body 2, an adjusting knob 31 is provided with in one end of described body 2, a vernier adjustment knob 32 is provided with at the afterbody of described adjusting knob 31, be provided with one first expansion link 41 at the other end telescopically of described body 2, be provided with one second expansion link 42 at the afterbody telescopically of the first described expansion link 41.
As shown in Figure 1 and Figure 2, the surface of the first described expansion link 41 is provided with scale.
As shown in Figure 1 and Figure 2, the surface of described body 2 is provided with scale.
The clearance meter of this invention is provided with for rotating the adjusting knob controlling length of telescopic bar on body, by the flexible rotation changing into adjusting knob of length, thus be exaggerated air line distance, also on adjusting knob, be provided with vernier adjustment knob simultaneously, thus substantially increase the measuring accuracy of clearance meter.
Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more functional module simultaneously, thus expands its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
