Abstract

The utility model discloses a vernier spiral micrometer, which pertains to the length measurement equipments of objects, in particular to the spiral micrometer. A small anvil and a fixed scale of the cursor spiral micrometer are fixed on a framework, a main knob, a vernier knob, a micrometer screw and a movable scale are connected together to be sleeved on the fixed scale by a precision thread, and the utility model is characterized in that: the periphery of the fixed scale is sleeved with a transparent annular vernier. The vernier spiral micrometer which is disclosed by the utility model is sleeved with the transparent annular vernier at the periphery of the fixed scale, so as to combine the principle of vernier measurement and the spiral micrometer, further to improve the measurement precision of the spiral micrometer simply and conveniently; as the vernier can move and rotate freely, compared with the prior art, the usage is more convenient and the reading is quick.

Description

The vernier micrometer caliper
Technical field
The utility model belongs to object length measuring equipment, particularly micrometer caliper.
Background technology
Usually micrometer caliper is that the instrument of the accurate Measuring Object length used always uses and extensively can reach 0.01mm, but there is fashion not satisfy the demands, ZL200520142423.3 discloses a kind vernier micrometer caliper, it is on the basis of existing micrometer caliper, a kind of novel micrometer caliper that designs in conjunction with the structural principle of vernier caliper.Its design feature is also to be carved with vernier graduation vertically on the periphery of existing micrometer caliper fixed muffle, and described vernier graduation is made up of many equally spaced parallel lines vertically.Because class vernier micrometer caliper is that the measuring principle of existing micrometer caliper and vernier caliper is combined, and makes it have both advantages.But since the class vernier graduation directly be engraved in use on the periphery of fixed muffle convenient inadequately.
The utility model content
The purpose of this utility model provides a kind of vernier micrometer caliper, and the vernier of this vernier micrometer caliper can arbitrarily move and rotate, and is more convenient for and movable mark is used.
The technical solution of the utility model is, a kind of vernier micrometer caliper, little anvil and fixedly scale be fixed on the framework, main knob, vernier adjustment knob and micrometric screw, movable mark connect together and are enclosed within fixedly on the scale by accurate thread, and its structure is: transparent annular vernier scale in fixing scale outer race.
The scale per unit scale of vernier scale is 0.9 times of movable mark, also can be 0.98 times.
The disclosed vernier micrometer caliper of the utility model transparent annular vernier scale in fixing scale outer race, thereby the vernier measuring principle is combined with micrometer caliper, improved the measuring accuracy of micrometer caliper simply and easily, because vernier scale can at will move and rotate, be more convenient for and movable mark is used, more convenient than prior art, reading is quick.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model,
Fig. 2 is the partial enlarged drawing of Fig. 1.
Among the figure, 1. framework, 2. little anvil, 3. micrometric screw, 4.Fixing scale, 5. annular vernier scale, 6. movable mark, 7. main knob, 8. vernier adjustment knob.
Embodiment
Embodiment of the present utility model is, as shown in the figure:
Embodiment 1, a kind of vernier micrometer caliper, little anvil 2 and fixedly scale 4 be fixed on the framework 1, main knob 7, vernier adjustment knob 8 and micrometric screw 3, movable mark 6 connect together and are enclosed within fixedly on the scale by accurate thread, it is characterized in that: transparent annular vernier scale 5 in fixing scale outer race.The per unit scale of vernier scale is 0.9 times of movable mark per unit scale.
Embodiment 2, a kind of vernier micrometer caliper, little anvil 2 and fixedly scale 4 be fixed on the framework 1, main knob 7, vernier adjustment knob 8 and micrometric screw 3, movable mark 6 connect together and are enclosed within fixedly on the scale by accurate thread, it is characterized in that: transparent annular vernier scale 5 in fixing scale outer race.The scale per unit scale of vernier scale is 0.98 times of movable mark per unit scale.
