Abstract
The utility model relates to an adjustable micrometric screw device. When the utility model is used, a small anvil and a frame can be adjusted to be connected with each other by threads and to do left motion and right motion, and a transversal groove is arranged in a fixing scale barrel; thus, the position of the fixing scale barrel can be conveniently adjusted, and the adjustable scale and the fixing scale are zero simultaneously; thereby, the length and the diameter of an object can be exactly tested.
Description
The utility model is a kind of survey instrument, is generally used for length, the diameter of Measuring Object.
The shortcoming that present employed micrometer caliper exists is zeroing inconvenience, reading easily makes a mistake, and when reality is used, needs first school zero, write down error amount, revise according to this value after the Measuring Object length, in addition, the fixedly scale of micrometer caliper is unadjustable on the direction of screw rod again, when causing movable mark to be zero, fixedly scale may be non-vanishing, easily misreads, and can not accurately measure object length and diameter.
The purpose of this utility model provides a kind of adjustable micrometer caliper, can turn the anvil and the fixing position of scale down by regulating, and reaches school zero effect.
At above-mentioned existing problems, the utility model proposes following solution: the little anvil of former mircrometer gauge is changed into can turn anvil down, fixedly have in the dial drum one along bar to groove, can regulate adjustable scale and fixing scale so easily, when micrometric screw with can turn anvil down and overlap the time, adjustable scale and fixedly scale be zero simultaneously.
The utlity model has and measure advantage convenient, accuracy of reading.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1, Fig. 2 are structural representation of the present utility model.
As shown in the figure, of the present utility model turning down between anvil (1) and the framework (3) to being threaded, but left and right adjusting is fixed on the framework (3) by fixed screw (9).Have a transverse concave groove (10) on the bar in fixing dial drum (8), on the bar, fixedly dial drum (8) can pass through groove (10) move left and right in fixedly dial drum (8) was fixed in by fixed screw (4).During use, adjusting can be turned the anvil (1) and the fixing position of scale (3) down, close up when turning down between anvil (1) and the micrometric screw (2), adjustable scale (5) is overlapped with fixedly zero point the zero point of scale (8), if do not overlap, scalable can be turned the position of anvil (1) down or adjust the fixedly position of dial drum (8) by screw (4), and overlapped zero point.This moment, but turn knob (6) was pulled out micrometric screw (2), just can measure the length of object exactly.
