Description
Technical Field
The utility model belongs to the technical field of measuring tool and specifically relates to a vernier caliper of measurable quantity arc length is related to.
Background
The vernier caliper is a measuring tool for measuring length, inner diameter, outer diameter and depth. The vernier caliper consists of a main ruler and a vernier attached to the main ruler and capable of sliding. The main scale is generally in millimeter units, the vernier has 10, 20 or 50 divisions, and the vernier caliper can be divided into ten-division vernier caliper, twenty-division vernier caliper, fifty-division vernier caliper and the like according to the division, wherein the vernier is 9mm in 10 divisions, 19mm in 20 divisions and 49mm in 50 divisions. The main scale and the vernier of the vernier caliper are provided with two pairs of movable measuring claws, namely an inner measuring claw and an outer measuring claw, wherein the inner measuring claw is generally used for measuring the inner diameter, and the outer measuring claw is generally used for measuring the length and the outer diameter.
The arc length data of an object to be measured are often met in the daily mapping process, the common vernier caliper can only be used for measuring the length and the radius, the arc length of the object cannot be measured, and the data are incomplete, so that a vernier caliper capable of measuring the arc length of the object is very necessary.
Disclosure of Invention
Not enough to prior art, the utility model provides a vernier caliper of measurable quantity arc length can effectively solve the problem that above-mentioned traditional vernier caliper exists, and overall structure is simple, and convenient operation realizes the measurement to the object arc length, and the data that obtain are more complete.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a vernier caliper of measurable quantity arc length, includes main scale, secondary scale, measures the claw outward, the fixed tape measure shell that is provided with on the secondary scale, be provided with flexible tape measure on the outer measuring claw, flexible tape measure one end fixed connection be in on the main scale, the other end passes the secondary scale with the inside fixed connection of tape measure shell, the pulling the secondary scale drives flexible tape measure is followed take suitable distance out in the tape measure shell and will measure claw laminating testee outward, locking outward measure the claw and read data on the flexible tape measure.
In the above technical solution, further, the flexible tape measure is made of plastic. The flexible measuring tape can be attached to the arc-shaped surface of the measured object.
In the above technical scheme, further, be provided with locking screw and fine setting gyro wheel on the vice chi. By the arrangement, the vernier caliper can be locked and finely adjusted, and the accuracy of reading data is guaranteed.
In the above technical solution, further, the flexible tape measure has a scale on one side of the flexible tape measure in centimeters and millimeters and a scale on the other side of the flexible tape measure in inches.
The utility model has the advantages that: fix on the main scale through flexible tape measure one end, through fixed the setting tape measure shell on the secondary scale, through setting up locking screw and fine setting gyro wheel on the secondary scale, original function has been realized to whole use to holistic simple structure, convenient operation makes can measure the arc length of object, and data is more complete.

Detailed Description
Referring to fig. 1-4, a vernier caliper of measurable quantity arc length, including main scale 1, vice chi 2, measure claw 3 outward, the fixed tape measure shell 4 that is provided with on the vice chi 2, be provided with flexible tape measure 5 on the outer measuring claw 3, 5 one end fixed connection of flexible tape measure are in on the main scale 1, the other end passes vice chi 2 with the inside fixed connection of tape measure shell 4, the pulling vice chi 2 drives suitable distance is taken out in the tape measure shell 4 and will the outer measuring claw 3 laminating testees, locking outer measuring claw 3 reads data on the flexible tape measure 5.
In order to ensure that the flexible measuring tape 5 is not easily damaged, the flexible measuring tape 5 is made of plastic, and has certain strength and very good flexibility.
In order to facilitate the reading of data by different users, one surface of the flexible measuring tape 5 is provided with centimeter and millimeter scales, and the other surface is provided with inch scales.
The utility model discloses a working process: and (2) measuring the measured arc length by eye, pulling the auxiliary ruler 2 out of the main ruler 1 for a certain distance, fixing the tape measure shell 4 on the auxiliary ruler 2, gradually pulling the flexible tape measure 5 out of the tape measure shell 4, attaching the outer measuring claw 3 on the measured arc surface, moving the auxiliary ruler 2 to fix the outer measuring claw 3, attaching the flexible tape measure 5 on the measured arc surface, rotating the locking screw 6 to fix the auxiliary ruler 2 on the main ruler 1, rolling the fine adjustment roller 7 to carry out final adjustment, and determining the measured arc length according to the scales of the outer measuring claw 3 at one end of the flexible tape measure 5 on the auxiliary ruler 2 and the tail end of the flexible tape measure 5.
The above is only an embodiment of the present invention, and is not a limitation to the present invention in any form, and the present invention does not depart from the technical solution of the present invention, and the simple modification, equivalent change or modification made by the present invention all fall into the protection scope of the present invention.
