Abstract
The utility model discloses a kind of vernier caliper, comprise main scale, being socketed on main scale can the vernier that connects of relative sliding, described main scale is provided with scale, the scale side described vernier being positioned at main scale has window, described main scale is provided with the main scale clamp for measuring, described vernier is provided with the vernier clamp for measuring, described main scale clamp is connected with described main scale by screw thread, described vernier clamp is connected with described vernier by screw thread, described main scale clamp and vernier clamp upper end are equipped with thread protrusion, corresponding, described main scale and described vernier lower end are equipped with tapped through hole.The utility model structure is simple, technology is reasonable, easy to operate, adapt to the high-acruracy survey of externally threaded interior line, the connection degree of depth of thread protrusion and tapped through hole can be regulated as required, thus the entire length of main scale clamp and vernier clamp, reduce the error rate of digital independent, and can use under the environment of insufficient light, bring very large help to surveying work.
Description
Technical field
The utility model relates to length measurement technique field, refers to a kind of vernier caliper especially.
Background technology
In recent years, the use of vernier caliper gets more and more, because vernier caliper can high-precision measurement Circular article external diameter, annulus article internal diameter, container depth etc.General, vernier caliper, mainly comprises main scale, and main scale is socketed with vernier.Meanwhile, main scale is provided with scale, and one that vernier is positioned at the scale of main scale has window, conveniently learns the data such as Circular article external diameter, annulus article internal diameter, container depth.But the measurement bayonet socket formed due to main scale clamp on vernier caliper and vernier clamp is only suitable for measuring smooth plane.And line has shape of threads in external thread, there is certain degree of tilt, if measured externally threaded interior line with general vernier caliper measurement, there will be very large error, have impact on the precision of measurement.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of vernier caliper, can pass through screw measurement bayonet socket, improve the precision of the diameter measurement to externally threaded interior line.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of vernier caliper, comprise main scale, being socketed on main scale can the vernier that connects of relative sliding, described main scale is provided with scale, the scale side described vernier being positioned at main scale has window, described main scale is provided with the main scale clamp for measuring, described vernier is provided with the vernier clamp for measuring, described main scale clamp is connected with described main scale by screw thread, described vernier clamp is connected with described vernier by screw thread, described main scale clamp and vernier clamp upper end are equipped with thread protrusion, corresponding, described main scale and described vernier lower end are equipped with tapped through hole, described main scale clamp and vernier clamp are provided with corresponding measurement screw thread, measure screw thread formation measurement card mouth for described two, described main scale is provided with the light source for throwing light on, and for opening the shift knob of light source.
As preferably, described window is provided with convex lens, can read data more accurately by convex lens.
The beneficial effect of technique scheme of the present utility model is as follows: structure is simple, technology is reasonable, easy to operate, adapt to the high-acruracy survey of externally threaded interior line, the connection degree of depth of thread protrusion and tapped through hole can be regulated as required, thus the entire length of main scale clamp and vernier clamp, reduce the error rate of digital independent, and can use under the environment of insufficient light, bring very large help to surveying work.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of vernier caliper embodiment of the present utility model.
Fig. 2 is the structural representation of measurement card notch portion embodiment in Fig. 1.
Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model provides a kind of vernier caliper for existing deficiency, as shown in Figure 1, comprise main scale 10, being socketed on main scale 10 can the vernier 20 that connects of relative sliding, described main scale is provided with scale 11, scale 11 side described vernier 20 being positioned at main scale 10 has window 21, described main scale 10 is provided with the main scale clamp 12 for measuring, described vernier 20 is provided with the vernier clamp 13 for measuring, described main scale clamp 12 is connected with described main scale 10 by screw thread, described vernier clamp 13 is connected with described vernier 20 by screw thread, described main scale clamp 12 and vernier clamp 13 upper end are equipped with thread protrusion 6, corresponding, described main scale 10 is equipped with tapped through hole with described vernier 20 lower end, described main scale clamp 12 and vernier clamp 13 are provided with corresponding measurement screw thread 14, measure screw thread 14 formation measurement bayonet socket 15 for described two, described main scale 10 is provided with the light source 23 for throwing light on, and for opening the shift knob 22 of light source 23.
Described window 21 is provided with convex lens 30.
Wherein, described light source 23 is connected with described main scale 10 by metal hose, can regulate the angle of illumination as required, and described light source 23 is LED, is provided with accumulator in described light source 23, and described shift knob 22 is contact button.When user pins shift knob, light source open, when user do not pin open the light button time, light source close.
This concrete enforcement structure is simple, technology is reasonable, easy to operate, adapt to the high-acruracy survey of externally threaded interior line, the connection degree of depth of thread protrusion and tapped through hole can be regulated as required, thus the entire length of main scale clamp and vernier clamp, reduce the error rate of digital independent, and can use under the environment of insufficient light, bring very large help to surveying work.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
