Embodiment Construction

[0021] like image 3 As shown, an improved structure of a caliper comprises a main ruler 1, a vernier ruler 2, a measuring claw 3 arranged on the main ruler 1 and the vernier ruler 2, and a positioning mechanism is provided on the side of the upper end of the vernier ruler 2 close to the measuring claw 3 I 20, the lower end of the vernier scale 2 is provided with a positioning mechanism II 21 which is in a diagonal structure with the positioning mechanism I 20, and the positioning mechanism I 20 and the positioning mechanism II 21 are respectively abutted against the upper end face and the lower end face of the main ruler 1 To limit the lateral displacement of the vernier ruler 2, the side of the lower end of the vernier ruler 2 close to the measuring claw 3 is provided with an elastic pressing mechanism 22 abutting against the lower end face of the main ruler 1, so that the positioning mechanism I 20 and the positioning mechanism II 21 are kept aligned with the main ruler. Th...

Abstract

The invention discloses an improved structure of a caliper, which comprises a main ruler, a vernier and measuring jaws arranged on the main ruler and the vernier, wherein a positioning mechanism I is arranged on one side of the upper end of the vernier which is near to the measuring jaw, a positioning mechanism II which forms a diagonal structure with the positioning mechanism I is arranged at the lower end of the vernier, the positioning mechanism I and the positioning mechanism II respectively push against the upper end surface and the lower end surface of the main ruler for limiting the lateral shift of the vernier, an elastic pressing mechanism is arranged on one side of the lower end of the vernier which is near to the measuring jaw, and the top of the elastic pressing mechanism is connected with the lower end surface of the main ruler for leading the positioning mechanism I and the positioning mechanism II to keep the state of pushing against the main ruler. The improved structure can solve the problem of inaccurate measurement result caused by excessive lateral gap of the existing caliper, eliminate errors produced by the aspect of measurement principle and improve the measurement precision of the caliper.

Description

technical field [0001] The present invention relates to a measuring tool, especially an improved structure of a caliper. Background technique [0002] The existing vernier calipers, height gauges and other caliper-type measurement tools seriously affect the accuracy of the measurement results due to the mismatch between the measurement surface and the reference measurement axis, and the lateral fit gap between the ruler body and the ruler frame. like figure 1 As shown in the figure, the fitting gap between the ruler body 01 and ruler frame 02 of measuring tools such as calipers and height rulers currently on the market is generally adjusted by the front and rear set screws 04 on the ruler frame. The pressure on 03 ensures that the ruler body slides along the datum plane of the ruler frame, thereby controlling the lateral clearance. However, there are the following problems when using this type of caliper: (1) During the manufacturing process, due to the limitations of the ...
