Embodiment Construction

[0015] See attached Figure 1~4 , the specific structure of the digital display apron length measuring instrument of the present invention is: comprise a base plate 3, on base plate 3 vertically be installed with main frame plate 22 and side frame plate 15 and constitute the skeleton of whole instrument. An upper measuring head 9 is installed above the main frame plate 22 , and the semicircular measuring column of the upper measuring head 9 is perpendicular to the plane of the main frame plate 22 . Two guide rods 4 perpendicular to the plane of the base plate are installed between the upper measuring head and the plane of the base plate, the upper ends of the guide rods 4 are fixedly connected with the upper measuring head, and the lower ends are fixedly connected with the base plate. A lower measuring head 6 is installed along the two guide rods 4 , and the lower measuring head 6 can move up and down along the two guide rods 4 . A rack 7 is installed on the lower measuring h...

Abstract

The present invention is one digital display rubber ring length measuring instrument for measuring the perimeter of elastic rubber ring. According to relevant specification, rated tension is applied during measurement. The instrument includes steel pedestal, main frame, upper measuring head, lower measuring head, guide rod, hand wheel, link rod mechanism, and air damper comprising cylinder, piston and throttle valve. Regulating the opening of the throttle valve makes the speed for the lower measuring head to contact the rubber ring approach zero, and this ensures the rated force applied and the accurate measurement. The measurement process includes moving the hand wheel to shift the lower measuring head to the upper end of the guide rod, jacketing the rubber ring on the semi-circular column of the measuring heads, releasing hand wheel to make the lower measuring head move downward to reach the rubber ring, and displaying digits.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a digital display apron length measuring instrument capable of measuring the circumference of an elastic apron. Background technique [0002] According to the textile industry standard FZ / T90039.1-92, when the width of the apron is W=24-35mm, the thickness δ=0.91-1.15mm. The rated tension applied in the measurement was 13N. The traditional length measuring instrument is spring type, hydraulic type and so on. [0003] Due to the particularity of measuring the length of the elastic element, there is no satisfactory solution so far. The traditional length measuring instrument is spring type, hydraulic type and so on. The spring-type measuring instrument uses a spring to apply a rated tension to the measured apron. From the knowledge of mechanics, the elongation of the spring is proportional to the strain. Therefore, when the circumference of the apron changes g...
