Description
Technical field
Physics experiments of high school appliance technology is the utility model is related to, more particularly to a kind of senior middle school's natural sciences Physical Experiment is used
Micrometer caliper.
Background technology
Micrometer caliper is also known as micrometer（micrometer）, spiral micrometer, micrometer, be more accurate than slide measure
Measurement length instrument, survey length with it and can be accurate to 0.01mm, measurement range is several centimetres, its part processing
Into the screw thread that pitch is 0.5mm, when it is rotated in the swivel nut of fixed sleeving, it will advance or retreat, moving casing and screw rod
It is connected, its periphery is divided into 50 lattices, and the number of full circle that screw rod rotates is gone to survey by the groove for being spaced 0.5mm on fixed sleeving
Amount, the part less than a circle are gone to measure by the groove on moving casing periphery, and final measurement, which needs to estimate, reads a decimal.
But existing senior middle school's natural sciences Physical Experiment with micrometer caliper in use there is in place of some shortcomings,
The smaller reading of scale dial plate is very convenient, error-prone, secondly without good taking structure, is typically held by chi frame
Take, fix determinand in chi frame again, cause taking very inconvenient, then have and treated by fixed gage button and micrometric screw gripping
Survey thing to measure, easily to be measured to be generally pylindrical, the stability of clamping is relatively low.
Utility model content
The purpose of this utility model is and a kind of senior middle school's natural sciences thing proposed in order to solve shortcoming present in prior art
Manage experiment micrometer caliper.
To achieve these goals, the utility model employs following technical scheme：A kind of senior middle school's natural sciences Physical Experiment is used
Micrometer caliper, including chi frame, fixed gage button is fixed with one end inwall of the chi frame, is led at the chi frame inner surface wall center
Cross support to be fixedly connected with fixed plate, and fixed plate upper surface offers serrated slot, is welded with the chi frame side appearance wall
