Abstract
The utility model provides a vernier steel ruler which comprises a steel ruler. The utility model is characterized in that the steel ruler is provided with a vernier and a measuring jaw, and the external end face which is fixed to the measuring jaw of the left side of the steel ruler is parellel with the zero position end face of the steel ruler. The utility model is provided with a vernier on the steel ruler, so the utility model can be used as a steel ruler, as well as a vernier caliper. The number reading value of the vernier reaches 0.05, so the measurement precision is improved greatly. The measurement range can reach 0 to 3000 millimters, and the cost is only one tenth of the vernier caliper.
Description
The utility model belongs to measurer, says so in more detail to the improvement of existing straight steel ruler.
Though existing straight steel ruler has used for many years, uses till today.But still exist some shortcoming: low as measuring accuracy, make usable range be restricted, some requires the measuring accuracy high product not measure with straight steel ruler.Though and existing vernier caliper measuring accuracy height also still exists some shortcomings: 1, the measurement range maximum can only be at 0～1000mm, and usable range also is restricted; 2, complex process, manufacturing cost height, selling price costliness are made in its many employing tool steel surface chromium plating.
The purpose of this utility model is in order to solve above-mentioned existing problems, a kind of vernier straight steel ruler to be provided.Its measuring accuracy is higher, and cost is low, both can be as straight steel ruler usefulness, again can be as vernier caliper, and also measurement range is big.
In order to achieve the above object, the utility model comprises straight steel ruler, it is characterized in that vernier and measuring jaw are housed on straight steel ruler, and the outer face that is fixed on straight steel ruler left side measuring jaw is concordant with the zero-bit end face of straight steel ruler (1).
The utlity model has following advantage: 1, owing to vernier is housed, the vernier reading value on the straight steel ruler: 0.05, improved measuring accuracy greatly; 2, because the measuring jaw outer face, left side that is contained on the straight steel ruler is concordant with the zero-potential surface of straight steel ruler, thereby it still can use as straight steel ruler, can use as vernier caliper again, and this is the not available function of existing vernier caliper; 3, measurement range is 0～800mm, 0～1000mm, 0～1500mm, 0～2000mm, 0～2500mm, 0～3000mm, thereby has enlarged measurement range; Though 4 measuring accuracy are more lower slightly than vernier caliper, require lower slightly large-scale workpiece very suitable for measuring accuracy; 5, manufacturing process is easy, and cost is low, only is 1/10 of vernier caliper.
Fig. 1 is a front view of the present utility model.
(1) straight steel ruler; (2) measuring jaw; (3) vernier; (4) rivet; (5) fixed screw; (6) gag; (7) holding screw; (8) fixed screw; (9) chi frame; (10) handwheel.
Referring to Fig. 1, straight steel ruler (1) adopts stainless steel to make, and in order still to keep the metering system of straight steel ruler (1), the outer face of left side measuring jaw (2) is concordant with the outer face (zero-potential surface) of straight steel ruler (1).Right side measuring jaw (2) is fixed on the straight steel ruler (1) by rivet (4).Right side measuring jaw (2) is an one with vernier (3).Chi frame (9) is fixing with holding screw (5), on the surface of contact of straight steel ruler (1) above and below and chi frame (9) gag (6) is housed, it is made by spring leaf, and the effect of gag (6) is to make vernier (3) when straight steel ruler (1) is gone up motion, motion is not steadily rocked.In order to prevent that vernier (3) slides when the reading, can screw holding screw (7) vernier (3) and straight steel ruler (1) are fixed.
Vernier of the present utility model (3) reading value can reach 0.05mm, increasing under the less situation of cost, has improved measuring accuracy greatly.Its cost is low, and is especially very suitable for measuring large-scale workpiece.
Claims (1)
1, a kind of vernier straight steel ruler, it comprises straight steel ruler (1), it is characterized in that vernier (3) and measuring jaw (2) are housed on straight steel ruler (1), the outer face that is fixed on straight steel ruler (1) left side measuring jaw (2) is concordant with the zero-bit end face of straight steel ruler (1).
