[0002] Hot rolling of medium and heavy plates is a key step in steel production. Thickness accuracy directly affects material strength. In the hot rolling process of medium and heavy plates, accurate measurement of plate thickness is of great significance to ensuring product quality. Contact thickness gauges are used to measure the data accurately. However, the core components of thickness gauges are mostly designed as an integral structure. This design limits the convenience of transportation to some extent, which may increase equipment transportation costs and even affect the production schedule, thereby reducing the flexibility of the thickness gauge. Utility Model Content

[0003] The purpose of this invention is to provide a thickness gauge for hot-rolled medium and heavy plates to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a medium-thick plate hot rolling thickness gauge, comprising a measuring plate and a protective plate, a display screen slidably connected to the outer surface of the measuring plate, a fixed plate fixedly connected below the display screen, a convex plate fixedly connected below the fixed plate, a guide rod two rotatably connected inside the protective plate, an L-shaped plate two fixedly connected to the outer surface of the guide rod two, an L-shaped plate one fixedly connected below the protective plate, a connecting plate provided below the fixed plate, a detector fixedly connected below the connecting plate, a slot provided inside the connecting plate, an installation structure provided on the connecting plate, the installation structure engaging with the convex plate, a positioning structure provided inside the L-shaped plate two, the positioning structure overlapping with the measuring plate, the installation structure including a guide rod one and a fixed column, the guide rod one rotatably connected to a rotating plate, a limit plate slidably connected to the fixed column, and a spring sleeved on the fixed column.

[0005] As a further preferred embodiment of this technical solution, the measuring plate is snapped into the protective plate, the convex plate is snapped into the L-shaped plate, and the measuring plate is snapped into the L-shaped plate.

[0006] As a further preferred embodiment of this technical solution, a detection gauge is fixedly connected to the outer surface of the detector, the convex plate is snapped into the slot, and the L-shaped plate is rotatably connected to the protective plate.

[0007] As a further preferred embodiment of this technical solution, the guide rod is fixedly connected to one side of the convex plate, the rotating plate is snapped into the convex plate, and the fixing post is fixedly connected to the other side of the convex plate.

[0008] As a further preferred embodiment of this technical solution, the fixing post is engaged in the limiting plate, the fixing post is connected to the limiting plate by a spring, and the limiting plate is engaged in the rotating plate.

[0011] This utility model provides a thickness gauge for hot-rolled medium-thick plates, which has the following advantages:

[0012] (1) This utility model sets up a fixed plate, a convex plate, a connecting plate, a slot and an installation structure to snap the convex plate below the fixed plate into the slot. When the fixed plate and the convex plate are aligned, the rotating plate is driven to rotate around the guide rod. When the rotating plate rotates, it applies a pulling force to the limiting plate. When the limiting plate moves on the surface of the fixed column, it will cause the spring to deform. After the rotating plate is snapped with the convex plate, it will contact the fixed column. When the limiting plate is released, it will be reset by the spring. After the reset, the limiting plate will snap with the rotating plate. The thickness gauge enables the detector and the display screen to be quickly assembled through the cooperation between the rotating plate, the limiting plate and the spring. The components of the thickness gauge can be disassembled and transported separately, which reduces the weight and volume of individual components, thereby reducing the difficulty and cost of transportation, and ensuring the flexibility of the thickness gauge.

[0013] (2) By setting up a protective plate and a positioning structure, the measuring plate is snapped into the protective plate, which drives the L-shaped plate two to rotate around the guide rod two. The turntable drives the threaded rod to rotate, and the sleeve plate will move on its surface. After the positioning plate moves, it will overlap with the upper right side of the measuring plate, so that the cooperation between the protective plate and the L-shaped plate one can play a certain protective role for the measuring plate and avoid damage to the measuring plate during transportation.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, a medium-thick plate hot rolling thickness gauge includes a measuring plate 1 and a protective plate 5. A display screen 2 is slidably connected to the outer surface of the measuring plate 1. A fixing plate 3 is fixedly connected to the lower part of the display screen 2. A convex plate 4 is fixedly connected to the lower part of the fixing plate 3. A guide rod 9 is rotatably connected inside the protective plate 5. An L-shaped plate 10 is fixedly connected to the outer surface of the guide rod 9. An L-shaped plate 6 is fixedly connected to the lower part of the protective plate 5. A connecting plate 11 is provided below the fixing plate 3. A detector 12 is fixedly connected to the lower part of the connecting plate 11. A slot 14 is provided inside the connecting plate 11. An installation structure 8 is provided on the connecting plate 11. The installation structure 8 is engaged with the convex plate 4. A positioning structure 7 is provided inside the L-shaped plate 10. The positioning structure 7 overlaps with the measuring plate 1. The installation structure 8 includes a guide rod 801 and a fixing column 803. The guide rod 801 is rotatably connected to a rotating plate 802. A limit plate 804 is slidably connected to the fixing column 803. A spring 805 is sleeved on the fixing column 803.

[0021] like Figure 1 and Figure 3 As shown, the measuring plate 1 is snapped into the protective plate 5, the convex plate 4 is snapped into the L-shaped plate 6, the measuring plate 1 is snapped into the L-shaped plate 6, the outer surface of the detector 12 is fixedly connected to the detection gauge 13, the convex plate 4 is snapped into the slot 14, and the L-shaped plate 10 is rotatably connected into the protective plate 5.

[0022] By setting the slot 14, when the fixing plate 3 is engaged with the connecting plate 11, the convex plate 4 below the fixing plate 3 will be engaged in the slot 14, so that the slot 14 plays a certain limiting role in fixing the fixing plate 3, and avoids the phenomenon of the fixing plate 3 and the connecting plate 11 shifting their positions when fixed.

[0023] Guide rod 801 is fixedly connected to one side of convex plate 4, rotating plate 802 is snapped into convex plate 4, fixing post 803 is fixedly connected to the other side of convex plate 4, fixing post 803 is snapped into limiting plate 804, fixing post 803 is connected to limiting plate 804 through spring 805, and limiting plate 804 is snapped into rotating plate 802;

[0024] By setting a spring 805, when a pulling force is applied to the limiting plate 804, the limiting plate 804 slides on the surface of the fixed column 803, which will cause the spring 805 to deform. This allows the spring 805 to play a certain auxiliary role in the movement of the limiting plate 804, preventing the limiting plate 804 from detaching during movement.

[0025] like Figure 4 As shown, the positioning structure 7 includes a threaded rod 701, an L-shaped plate 2 10 snapped into an L-shaped plate 1 6, the threaded rod 701 being rotatably connected to an L-shaped plate 2 10, a turntable 703 being fixedly connected to one end of the threaded rod 701, a sleeve plate 702 being threadedly connected to the outer surface of the threaded rod 701, and a positioning plate 704 being fixedly connected to the lower part of the sleeve plate 702, the positioning plate 704 overlapping with the measuring plate 1;

[0026] By setting the threaded rod 701 and the positioning plate 704, when the measuring plate 1 is snapped into the protective plate 5, the turntable 703 drives the threaded rod 701 to rotate. After the positioning plate 704 moves, it will overlap with the upper right side of the measuring plate 1, thereby positioning the measuring plate 1 after it is snapped in, and preventing the measuring plate 1 from becoming loose during transportation.

[0027] This utility model provides a thickness gauge for hot-rolled medium-thick plates, the specific working principle of which is as follows:

[0028] When the thickness gauge is not in use, the measuring plate 1 can be snapped into the protective plate 5, and the convex plate 4 below the measuring plate 1 will overlap with the L-shaped plate 6. Then, the L-shaped plate 10 will be rotated around the guide rod 9. After the L-shaped plate 10 is rotated, it will be inserted into the L-shaped plate 6. The turntable 703 will drive the threaded rod 701 to rotate, and the sleeve plate 702 will move on its surface. After the positioning plate 704 moves, it will overlap with the upper right side of the measuring plate 1.

[0029] When the thickness gauge is in use, it will be separated from the protective plate 5, and then the convex plate 4 below the fixed plate 3 will be snapped into the slot 14. When the fixed plate 3 and the convex plate 4 are aligned, the rotating plate 802 will rotate around the guide rod 801. When the rotating plate 802 rotates, it will apply a pulling force to the limiting plate 804. When the limiting plate 804 moves on the surface of the fixed post 803, it will cause the spring 805 to deform. After the rotating plate 802 is snapped into the convex plate 4, it will contact the fixed post 803. When the limiting plate 804 is released, it will be reset by the spring 805. After being reset, the limiting plate 804 will be snapped into the rotating plate 802.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
