[0002] Steel plate curvature refers to the degree to which the plane shape of the steel plate deviates from the ideal plane, including bending, convexity, concave and other states. The method of measuring steel plate curvature on the production site can be done by manual judgment through visual observation, but this operation is highly subjective and not precise enough to meet the high requirements for steel plate curvature measurement; another method is the wire drawing method, which uses a long wire and a ruler for measurement.

The on-site personnel configuration is often not enough, and the measurement effect is not ideal. Utility Model Content

[0027] Example 1

[0028] Figure 1 FIG. 1 is a schematic diagram of the structure of the steel plate buckling measuring device provided in this embodiment. Figure 1 As shown, the steel plate deflection measuring device comprises a main body 1, and a slot 2 is provided on the main body 1;

[0029] The telescopic rod 3 is slidably connected to the body 1 through the slot 2;

[0030] The bottoms of both ends of the body 1 and the bottom of the free end of the telescopic rod 3 are rotatably connected with a measuring ruler 4.

[0031] like Figure 3 As shown, when measuring the depression 12 of the steel plate, the telescopic rod 3 is pulled out according to the depression width, so that the lower surface of the body 1 can contact the non-depressed part of the steel plate, and the middle measuring ruler 4 is rotated to a vertical position and extended into the depression, and the maximum scale reading at the depression 12 of the steel plate is read, which is the deflection value of the steel plate;

[0032] like Figure 4 As shown, when measuring the protrusion 11 of the steel plate, pull out the telescopic rod 3 according to the required width measurement, so that the measuring scales 4 at both ends are respectively located on both sides of the protrusion, turn the measuring scales 4 at both ends to a vertical position, and place the main body 1 horizontally above the protrusion 11 of the steel plate, so that the bottom of the measuring scale 4 contacts the non-protruding part of the steel plate, and find the maximum reading of the measuring scales 4 at both ends, which is the deflection value of the steel plate.

[0033] In this embodiment, the main body 1 and the telescopic rod 3 are provided with a receiving groove for receiving the measuring scale 4 .

[0034] The measuring ruler 4 can be rotated into the receiving groove for storage when not in use.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, a vertical limit groove 5 is provided above the connection between the main body 1 and the telescopic rod 3 and the measuring scale 4, a rivet 6 is slidably connected in the limit groove 5, and the rivet 6 is rotatably connected to the measuring scale 4; a spring 7 is connected between the rivet 6 and the top side groove wall of the limit groove 5.

[0036] A vertical limit groove 5 is provided above the connection between the main body 1 and the telescopic rod 3 and the measuring scale 4, and a spring 7 is arranged in the limit groove 5. A rivet 6 is slidably connected in the limit groove 5, and the rivet 6 is rotatably connected to the measuring scale 4; a spring 7 is connected between the rivet 6 and the top side groove wall of the limit groove 5, so that when the steel plate depression 12 is shallow and the steel plate protrusion 11 is not high, the measuring scale 4 can compress the spring 7 upward through the rivet 6 after contacting the steel plate, and adjust the vertical length of the measuring scale 4, thereby ensuring that when the steel plate depression 12 is shallow, the bottom of the middle measuring scale 4 and the bottom of the main body 1 and the telescopic rod 3 are in contact with the steel plate, and when the steel plate protrusion 11 is not high, the bottom of the measuring scale 4 at both ends and the middle bottom of the measuring device can contact the steel plate, thereby ensuring the accuracy of the measurement data, and after the measuring scale 4 is away from the steel plate, the spring 7 controls its reset.

[0037] In this embodiment, a sliding rod 8 is provided on the main body 1 , a sliding groove 9 is provided on the telescopic rod 3 along the length direction, and the sliding rod 8 is slidably connected in the sliding groove 9 .

[0038] When the telescopic rod 3 is pulled out and retracted, the sliding rod 8 slides in the sliding groove 9, thereby improving the stability of the movement of the telescopic rod 3 and preventing the telescopic rod 3 from being pulled away from the body 1.

[0039] In this embodiment, a level ruler 10 is disposed on the top of the body 1 .

[0040] The level ruler 10 can be used to observe whether the detection device is placed horizontally, thereby further improving the accuracy of data detection.

[0041] In this embodiment, the length of the telescopic rod 3 is the same as that of the body 1 .

[0042] The telescopic rod 3 and the main body 1 having the same length can enable the telescopic rod 3 to be fully retracted into the main body 1 as much as possible, thereby reducing the space occupied by the measuring device when not in use.

[0043] In this embodiment, the level ruler 10 is located at the right end of the body 1 .

[0044] The level ruler located at the right end of the body 1 can be placed as close as possible to the middle of the measuring device after the telescopic rod 3 is extended, so as to improve the accuracy of the horizontal detection.

[0045] In this embodiment, the measuring scale 4 is provided with scales.

[0046] The measuring ruler 4 is provided with scales for easy reading.

[0047] In this embodiment, the diameter of the spring 7 is smaller than the width of the limiting groove 5 .

[0048] The diameter of the spring 7 is smaller than the width of the limiting groove 5 , which can ensure that the spring 7 can be extended and retracted up and down in the limiting groove 5 .

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
