Technical field
The present invention relates to the five metals field, particularly relate to a kind of screw-thread micrometer with magnifier.
Background technology
Vernier caliper or screw-thread micrometer are adopted in measurement to tiny device usually, wherein vernier caliper is convenient to measure internal diameter, external diameter, length of object etc., be subjected to the restriction of body form little, then the precision of vernier caliper often can not be satisfied the demand, the ratio of precision vernier caliper of screw-thread micrometer is high, therefore screw-thread micrometer is being adopted in the high measurement of accuracy requirement often, but its number of degrees are inconvenient, easily cause reading error.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of screw-thread micrometer with magnifier, by using magnifier to amplify the number of degrees of screw-thread micrometer, increased the degree of stability of measuring, simplify the operation, raise the efficiency, popularizing of the screw-thread micrometer with magnifier, market outlook are widely arranged.
for solving the problems of the technologies described above, the invention provides a kind of screw-thread micrometer with magnifier, comprise: screw rod, knob, fixed knob, measuring staff, gage button and magnifier, described screw rod comprises sleeve pipe and swivel nut, described swivel nut is fixed on the outside of described sleeve pipe, the precision of described sleeve pipe is 0.5mm, the precision of described swivel nut is 0.01mm, one end of described screw rod connects described knob, the other end connects described measuring staff, described fixed knob is fixed on described screw rod, the position that is used for fixing described measuring staff, described gage button connect the screw rod of telling and extend to the front end of described measuring staff, described magnifier is fixed on the upper end of described screw rod.
In a preferred embodiment of the present invention, described knob is used for driving the motion of described swivel nut.
In a preferred embodiment of the present invention, it is 0.5mm that described swivel nut rotates the length of a week correspondence on sleeve pipe.
In a preferred embodiment of the present invention, the enlargement ratio of described magnifier is 5 times.
The invention has the beneficial effects as follows: the present invention with the screw-thread micrometer of magnifier have simple in structure, be conducive to large-scale production, laborsaving, reading simple to operate precisely, amplify the advantages such as convenient observations of the number of degrees, popularizing of the screw-thread micrometer with magnifier, market outlook are widely arranged.

In accompanying drawing, the mark of each parts is as follows: 1, screw rod, 2, knob, 3, fixed knob, 4, measuring staff, 5, gage button, 6, magnifier.
Embodiment
Below will the technical scheme in the embodiment of the present invention be clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiment that obtain under the creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A kind of screw-thread micrometer with magnifier comprises: screw rod 1, knob 2, fixed knob 3, measuring staff 4, gage button 5 and magnifier 6.
described screw rod 1 comprises sleeve pipe and swivel nut, sleeve pipe maintains static, swivel nut is rotatable, described swivel nut is fixed on the outside of described sleeve pipe, the precision of described sleeve pipe is 0.5mm, described swivel nut is divided into 50 little lattice with the length of 0.5mm, precision is 0.01mm, one end of described screw rod 1 connects described knob 2, the other end connects described measuring staff 4, described fixed knob 3 is fixed on described screw rod 1, the position that is used for fixing described measuring staff 4, described gage button 5 connect the screw rod of telling 1 and extend to the front end of described measuring staff 4, when gage button 5 and measuring staff 4 seamless link, the reading of described screw rod 1 is zero, corresponding synchronous, the convenient conversion, described magnifier 6 is fixed on the upper end of described screw rod 1, be used for amplifying reading, conveniently observe and read, reduce reading error, increase degree of stability and the precision measured.
Described knob 2 is used for driving the motion of described swivel nut, thereby by the rotation of turning knob 2 with movable snail sleeve, convenient and strength-saving.
It is 0.5mm that described swivel nut rotates the length of a week correspondence on sleeve pipe, the length of 0.5mm on screw rod is divided into 50 assigns on swivel nut, has improved the precision of measuring.
The enlargement ratio of described magnifier 6 is 5 times, the convenient observation and reading.
The classify beneficial effect of booking software of the present invention is:
One, by using magnifier to amplify reading, thereby convenient the observation and reading increased degree of stability and the accuracy of reading;
Two, by swivel nut, the length of 0.5mm is divided into 50 parts, thereby has increased the precision of measuring, reduced the degree of error of measuring;
Three,, by using fixed knob that measuring staff is fixed, effectively fixed the position of object being measured, thereby prevented the change of position and cause error.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in scope of patent protection of the present invention.
