[0015] The technical solution of the present utility model will be further described below with reference to the embodiments shown in the accompanying drawings.

[0016] The utility model is a measuring converter for measuring an indicator, comprising a conversion mechanism matched to an indicator 1, wherein a coaxial measuring rod I1-2 is slidably fitted in a shaft sleeve 1-1 at the lower end of the indicator 1, and the measuring rod I1-2 is moved downwardly and positioned outside the shaft sleeve 1-1 under the action of a spring assembly I (arranged in the shaft sleeve 1-1), and a probe I is coaxially mounted on the lower end of the measuring rod I1-2. Figure 1 、 Figure 2 shown.

[0017] The conversion mechanism includes a base shell 2 and a right-angle lever 5. A vertical mounting hole I (which leads to the interior of the base shell 2) is provided on the right side of the upper end face of the base shell 2, and a horizontal mounting hole II (which leads to the interior of the base shell 2) is provided on the left end face of the lower part of the base shell 2. The axis lines of the mounting hole I and the mounting hole II are in the same vertical plane. A sleeve 3 is coaxially installed in the mounting hole II. The right part of the sleeve 3 extends into the base shell 2 and is located on the left side of the sleeve 1-1. A coaxial measuring rod II4 is slidably fitted in the sleeve 3. Under the action of the spring assembly II (provided in the sleeve 3), the left part of the measuring rod II4 returns to the left and is located outside the sleeve 3, while the right part of the measuring rod II4 extends outside the right end of the sleeve 3 (located inside the base shell 2). A probe II is coaxially installed on the left end of the measuring rod II4, as shown in FIG. Figure 1 、 Figure 2 shown.

[0018] The lever 5 is hinged in the base shell 2 through the shaft 10, and its hinged part is at a right angle to the lever 5. The active arm of the lever 5 is vertically downward from the hinge point, and the driven arm of the lever 5 is horizontally rightward from the hinge point. A coaxial pin body Ⅰ6 is installed on the driven arm corresponding to the axis of the measuring rod Ⅰ1-2, and a coaxial pin body Ⅱ7 is installed on the active arm corresponding to the axis of the measuring rod Ⅱ4. A coaxial steel ball 8 (half of the ball is exposed) is embedded in the pin body Ⅱ7. The probe Ⅰ of the measuring rod Ⅰ1-2 is in conflict with the pin body Ⅰ6 (point contact Ⅰ), and the right end of the measuring rod Ⅱ4 is in conflict with the steel ball 8 (point contact Ⅱ). The transmission ratio of the lever 5 is 1:1, that is, the distance from the point contact Ⅱ to the hinge point is equal to the distance from the point contact Ⅰ to the hinge point. Figure 1 、 Figure 2 shown.

[0019] The operation mode of the utility model is:

[0020] The probe II of the measuring rod II4 collides with the workpiece to be measured, and the measuring rod II4 is compressed to the right by a measuring amount. The measuring rod II4 pushes the active arm to make the passive arm rotate by the same angle, and the probe I of the measuring rod I1-2 is compressed upward by the passive arm by the same measuring amount. The measured amount is read through the indicator table 1, and the reading is the measurement value of the workpiece to be measured.
