[0002] H-shaped steel, also known as I-shaped steel and H-shaped steel, is a common steel cross-section shape. Its cross-section consists of two parallel flange plates and a web connecting the two flange plates. The flange plates of the H-shaped steel provide a larger bending section modulus, so that it exhibits good bending performance when subjected to bending loads. At the same time, the width of the flange plates is large, which increases the lateral stiffness of the H-shaped steel. The shape of the H-shaped steel is simple and easy to process and install. Although the structure is simple, there are different types.

[0034] Specifically, the fixing rod 2 13 can provide guidance for the up and down movement of the splint 3 to prevent it from deviating from the established motion trajectory, causing the device to fail to operate normally. The gear 16 can drive the rack 12 to move up and down by rotating, thereby pulling the splint 3 up and down along the fixing rod 2 13 to adapt to H-shaped steel flanges of different thicknesses and position the device thereon.

[0035] Please see the attached Figure 3 - Attachment Figure 5 The right side of the hollow protective shell 1 is fixedly connected to a fixing rod 4, and a rotating rod 8 is rotatably connected between the adjacent fixing rods 4. The fixing rod 4 provides a fulcrum for the rotation of the rotating rod 8. The outer wall of the rotating rod 8 is rotatably connected to a rotating disk 5. A plurality of sliding rods 11 are fixedly connected to the left and right edges of the rotating disk 5. The sliding rod 11 can slide in the hollow protective shell 1 by rotating the rotating disk 5 left and right. The middle part of the left side of the rotating disk 5 is rotatably connected to a rotating shaft 3 6, and the left end of the rotating shaft 3 6 is rotatably connected to a pointer 7. The pointer 7 is used to indicate the angle of rotation. The bottom of the pointer 7 is fixedly connected to a counterweight 9.

[0037] Please see the attached Figure 4 - Attachment Figure 6 The folding structure 2 includes a handle 201. The left side of the handle 201 is fixedly connected to the right side of the hollow protective shell 1. The middle part of the inner wall of the handle 201 is rotatably connected to a rotating column 202. The handle 201 is used to help the user hold the device for use. A plurality of limiting grooves 206 are provided on the upper and lower sides of the handle 201. The inner wall of the rotating column 202 is rotatably connected to a rotating shaft 204. The rotating shaft 204 is used to rotate the middle part of the handle 201 to fold it. The outward end of the rotating shaft 204 is fixedly connected to a rotating plate 203. The left and right sides of the rotating plate 203 are fixedly connected. The sides are fixedly connected with a card column 205, the inner wall of the splint 3 is slidably connected with a sliding plate 209, the card column 205 can be engaged with the limiting groove 206, the right side of the sliding plate 209 is rotatably connected with a rotating shaft 208, the outer wall of the rotating shaft 208 is rotatably connected to the limiting disk 207, the rotating shaft 208 is used to help the sliding plate 209 rotate and fold, the front and rear sides of the handle 201 are provided with anti-slip grooves 21, the outer wall of the card column 205 is slidably connected with the inner wall of the limiting groove 206, and the anti-slip grooves 21 are used to prevent the user from slipping when using the handle 201;

[0038] Specifically, the anti-slip groove 21 can improve the grip and anti-slip performance of the handle 201, and increase the friction of the handle 201, thereby improving the user's grip comfort during use. The clamping column 205 can slide with the inner wall of the limiting groove 206, thereby being inserted into the limiting groove 206 to limit the rotation and folding of the handle 201, preventing the handle 201 from folding during use and causing the detection result to become invalid. The handle 201 is used to facilitate the user to align it with the flange for clamping when measuring the inclination of the flange through the device.

[0039] Please see the attached Figure 2 - Attachment Figure 4 , the outer wall of the sliding rod 11 is fixedly connected with a plurality of scales 10, and the plurality of scales 10 are fixedly connected at the same horizontal height. The bottom of the sliding plate 209 is fixedly connected with an anti-slip pad 18. The scale 10 is used to help the user observe the position of the sliding rod 11 and thus understand the degree. The outer wall of the rotating plate 203 is fixedly connected with a rubber pad 22. The outer wall of the rotating disk 2 14 is provided with a plurality of anti-slip grooves 23. The outer wall of the rotating disk 2 14 is rotatably connected to the inner wall of the hollow protective shell 1. The rubber pad 22 is used to increase the friction force of the outer wall of the rotating plate 203. The outer wall of the splint 3 is slidably connected to the inner wall of the hollow protective shell 1. The rotating disk 1 5 is square-bottomed dome-shaped. The square-bottomed dome-shaped rotating disk 1 5 can better perform detection;

[0040] Specifically, the design of the anti-slip groove 23 can not only increase the friction of the rotating disk 2 14, making it easier for the user to rotate the rotating disk 2 14, but the rubber pad 22 can also increase the friction between the user and it, thereby preventing the user from slipping their hands and losing their grip on the rotating plate 203. The scale 10 at the same horizontal height can accurately read the distance the sliding rod 11 is extended, and then read its front and rear tilt angles.

[0041] Working principle: When testing the inclination of the H-shaped steel flange, first place it between the clamping plate 3 and the fixed plate 17, then rotate the rotating disk 2 14 to drive the transmission shaft 15 to rotate, and then drive the gear 16 to rotate, thereby driving the clamping plate 3 to move downward along the fixed rod 2 13 through the rack 12, until it cooperates with the fixed plate 17 to clamp the device at the flange. The front and rear horizontal imbalance of the flange will cause the rotating disk 1 5 to rotate along the rotating rod 8, so that the sliding rod 11 slides in the hollow protective shell 1, and the degree at the scale 10 can be read to display the inclination angle. If it tilts left or right, the counterweight 9 pulls down to keep the pointer 7 horizontal and vertical, and rotates along the rotating shaft 3 6 to indicate the rotation angle through the top of the pointer 7;

[0042] When the handle 201 is no longer needed and needs to be folded, first pull the sliding plate 209 outward until the second rotating shaft 208 extends outward and then rotates along the second rotating shaft 208. Then, rotate the first rotating shaft 204 on the upper and lower sides of the handle 201, thereby driving the rotating plate 203 to rotate, and then the clamping column 205 is disengaged from the limiting groove 206, and then the handle 201 is folded along the rotating column 202.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
