An insertion hole 19 is provided on the surface of the pin 20. A vertical plate 24 is slidably connected to the middle end of the pin 20. A support spring 23 is fixedly connected between the right side of the vertical plate 24 and the right end of the pin 20. A rotating disk 15 is fixedly connected to the top of the vertical plate 24. A guide groove 17 is provided on the surface of the rotating disk 15. An L-shaped locking rod 13 is slidably connected between the surface of the guide groove 17 and the upper end of the annular frame 3.

[0024] In this technical solution, the pin 20, the insertion hole 19, the support spring 23, and the pin groove 18 limit the rotation direction of the upright plate 24, the rotating disk 15, and the guide groove 17. This allows personnel to easily rotate the upright plate 24, the rotating disk 15, and the guide groove 17 during the installation of the float-type level gauge 4 between it and the pool body 1. The rotation of the guide groove 17 causes the L-shaped locking rod 13 to be inserted into the annular locking groove 9 on the fixed disk 6. This locks and limits the float-type level gauge 4, the fixed disk 6, the annular frame 3, the guide pipe 2, and the pool body 1 during installation, thus achieving the goal of quickly installing and fixing the float-type level gauge 4. The overall operation is simple and quick, effectively improving the efficiency of personnel installation work and greatly facilitating subsequent disassembly and maintenance.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, the float-type level gauge 4 is fixedly connected to the left side with a connecting strap 8, and a protective cover 7 is fixedly connected to the left side of the connecting strap 8. The fixed plate 6 has positioning holes 5 around its perimeter. The top of the guide tube 2 is fixedly connected to positioning posts 12 around its perimeter. The bottom of the fixed plate 6 is fixedly connected to a fixed cylinder 11. Both ends of the fixed cylinder 11 are fitted with rubber sealing rings 10. The annular groove 16 is formed between the perimeter of the inner cavity of the annular frame 3. The surface of the rotating disk 15 is slidably connected to the surface of the annular groove 16. The surface of the L-shaped locking rod 13 is slidably connected to a guide slide rod 14. The two sides of the guide slide rod 14 are fixedly connected to the upper end of the inner cavity of the annular frame 3. The bottom of the pin 20 has a limiting groove 21. The lower end of the upright plate 24 is fixedly connected to a limiting block 22. The surface of the limiting block 22 is slidably connected to the surface of the limiting groove 21. A reinforcing rod is fixedly connected between the upper end of the upright plate 24 and the left end of the bottom of the rotating disk 15, and the reinforcing rod is inclined.

[0027] In this technical solution, the protective cover 7 facilitates the protection of the front of the display screen on the float level gauge 4. The positioning hole 5 and positioning post 12 allow for positioning between the fixed plate 6 and the guide tube 2 during the installation of the float level gauge 4, preventing rotation of the fixed plate 6 and the float level gauge 4 after installation. The fixed cylinder 11 and rubber sealing ring 10 ensure that they can be inserted into the guide tube 2 during the installation of the fixed plate 6 and the float level gauge 4. The inside of the through pipe 2 is sealed and protected. The annular groove 16 is used to support and guide the rotating disk 15. The guide slide rod 14 is used to guide the L-shaped locking rod 13. The limiting groove 21 and the limiting block 22 are used to limit the pin 20 and the upright plate 24, preventing the pin 20 from detaching from the surface of the upright plate 24 under the force. The reinforcing rod is used to effectively improve the connection strength between the upright plate 24 and the rotating disk 15.

[0028] The working principle of this utility model is as follows: When it is necessary to install and use the float-type level gauge 4 with the pool body 1, a screwdriver is inserted into the insertion hole 19 on the pin 20. By pushing the screwdriver and the pin 20 to move, the support spring 23 can be stretched until the pin 20 can be disengaged from the surface of the pin groove 18. Then, the operator can push the screwdriver and the pin 20 to rotate, which can drive the upright plate 24, the rotating disk 15 and the guide groove 17 to rotate. While the guide groove 17 is rotating, it can push the L-shaped locking rod 13 along the inclined surface, so that the L-shaped locking rod 13 can enter the annular frame 3. By inserting the lower end of the float-type level gauge 4 into the pool body 1 along the inner cavity of the guide tube 2, the bottom of the fixing disk 6 can be attached to the surface of the guide tube 2 and the annular frame 3. By rotating the screw sleeve and the pin 20 in the opposite direction, the upright plate can be rotated. 24. The rotating disk 15 and guide groove 17 rotate. While the guide groove 17 rotates, it can push the L-shaped locking rod 13 along the inclined plane to move, so that the L-shaped locking rod 13 can be inserted into the annular groove 9 under the action of movement. This can lock and limit the fixed disk 6 and the float level gauge 4. At the same time, the personnel can stop pushing the screwdriver and, driven by the tension of the support spring 23, allow the pin 20 to be inserted into the pin groove 18 in its original position. This can limit the rotation direction of the upright plate 24, the rotating disk 15 and the guide groove 17, and prevent the L-shaped locking rod 13 from disengaging from the surface of the annular groove 9. This ensures the stability of the fixed disk 6 and the float level gauge 4 being locked and limited, thus achieving the purpose of quickly installing and fixing the float level gauge 4. The overall operation is simple and quick, effectively improving the efficiency of personnel installation work, and bringing great convenience to personnel for subsequent disassembly and maintenance work.
