[0003] At present, there are three main types of vernier calipers on the market: mechanical, dial and digital. Since refractory shaped products have different shapes and certain degrees of inaccuracy, but their sizes are relatively fixed, it is difficult to find the exact position of the part to be measured using a universal vernier caliper in actual measurement, and the efficiency is very low. In addition, due to the inaccuracy of the measured product, the measurement will be biased. Utility Model Content

[0023] In order to better explain the present invention, the main contents of the present invention are further explained below in combination with specific embodiments, but the contents of the present invention are not limited to the following embodiments.

[0024] like Figure 1-2 The utility model is a caliper for refractory shaped products, which is a stainless steel caliper and includes a caliper body 1, a positioning rod 2 and a measurement reference plate 6.

[0025] The caliper body 1 is an integrally formed structure, including a ruler body 12 at the top and measuring jaws 11 at both sides, and an internal measuring area 13 is surrounded by the ruler body 12 and the measuring jaws 11. In this specific embodiment, the caliper body 1 is 200 mm long, 140 mm wide, and 2 mm thick.

[0026] The measurement reference plate 6 is suspended in the measurement area 13 by the positioning rod 2 ; one end of the positioning rod 2 is slidably connected to the ruler body 12 , and the other end of the positioning rod 2 is fixedly connected to the measurement reference plate 6 .

[0027] like Figures 1 to 3 As shown, the middle portion of the ruler body 12 has a through hole for the positioning rod 2 to pass through, and the end of the through hole away from the measurement reference plate 6 is provided with a limiting ring 121 to prevent the reset spring 3 from falling out.

[0028] The positioning rod 2 is inserted into the through hole of the ruler body 12 and is slidably connected to the ruler body 12. In this specific embodiment, the caliper body 1 is bilaterally symmetrical with the positioning rod 2 as the axis; the positioning rod 2 is 160 mm long and 5 mm in diameter.

[0029] A measurement reference plate 6 perpendicular to the positioning rod 2 is fixedly provided at the lower end of the positioning rod 2. Both ends of the measurement reference plate 6 are provided with measurement plate clamping claws 61, and the measuring claws 11 are provided with a scale 4; the measurement plate clamping claws 61 slide on the scale 4, so that the measurement reference plate 6 can move up and down in the measurement area 13, and the product size can be intuitively read by the position of the measurement reference plate 6 on the scale 4. In this specific embodiment, the length of the measurement reference plate 6 is 145 mm and the thickness is 2 mm.

[0030] The measuring claws 11 on both sides are provided with a scale 4. Figure 4 As shown, the vertical gap of each small scale is 0.5mm, the vertical gap of each large scale is 2.5mm, and each large scale contains 5 small scales. When reading data, the accuracy of each small scale is 0.02mm, and the large scale is 0.1mm.

[0031] The bottom ends of the two measuring claws 11 are provided with buckles 5 for limiting the active area of ​​the measuring reference plate 6 to prevent the measuring plate claws 61 from falling out, thereby preventing the measuring reference plate 6 and the positioning rod 2 from falling off.

[0032] A return spring 3 is sleeved on the positioning rod 2. Figure 3 As shown, the top of the return spring 3 is located below the limiting ring platform 121, and the return spring 3 is limited below the top of the through hole to prevent the spring from sliding out of the top of the through hole. In this specific embodiment, the diameter of the return spring 3 is 5.5mm and the length is 160mm.

[0033] The bevel angle of the caliper of the utility model is calculated according to the standard size of the refractory shaped product. The bevel angle is the angle between the measuring surface of the measuring jaw 11 and the measuring surface of the ruler body 12. The two bevel angles are the same and greater than 90°. In this specific embodiment, the bevel angle is 92.2°.

[0034] When not measuring, the measurement reference plate 6 is fixed to the bottom end of the caliper body 1 by the thrust of the return spring 3 , and the movable area of ​​the measurement reference plate 6 is limited within the measurement area 13 by the setting of the buckle 5 .

[0035] When the caliper is actually used, the measuring caliper body 1 is held in hand, the measuring reference plate 6 is placed close to the measuring part and pressed to make the measured object enter the measuring area 13. When the positioning rod 2 moves into position, the size of the measured object can be obtained by measuring the reading indicated on the ruler 4 by the end surface of the measuring reference plate 6 that contacts the measured object. After reading the data, after the measured object is taken out, the measuring reference plate 6 will return to the buckle 5 at the bottom of the caliper body 1 under the thrust of the reset spring 3.

[0036] Other parts not described belong to the prior art.
