DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] See Figure 1 —— Figure 2 The liquid level gauge of the present invention comprises: a dial base 1, a fixed plate 4, a connecting rod 5, a rotating shaft 6, a float 7, and a cover 11. Three connecting rods 5 and a rotating shaft 6 are fixedly connected between the dial base 1 and the fixed plate 4. The float 7 is inserted through the connecting rods 5 and the rotating shaft 6. A center base 3 is provided at the center of the dial base 1, and the top of the rotating shaft 6 is inserted into the bottom limit of the center base 3. A pointer magnet and a pointer are provided at the top of the center base 3. A rotating shaft magnet is provided at the top of the rotating shaft 6, and the rotating shaft magnet corresponds to the pointer magnet. When the rotating shaft magnet rotates with the rotating shaft 6, the pointer magnet is prompted to rotate with the rotating shaft magnet, thereby realizing the rotation of the pointer.

[0023] The dial base 1 of the present invention includes a circular disc 2, the upper end surface of which is formed with a raised dial base portion 18. This portion 18 defines a mounting hole 19 that penetrates the disc 2 and is intended for bolted installation. This design allows the level gauge to be installed in the fuel tank by bolting through the mounting hole 19. This prevents the mounting hole 19 from cracking when subjected to stress, thereby enhancing the stability of the gauge's installation.

[0024] The dial base 1 of the present invention has an annular, concentric inner ring 8 and outer ring 9 projecting from its upper end surface. The center seat 3 is located at the center of the inner ring 8. The inner sidewall of the inner ring 8 forms a step for accommodating the dial. The inner sidewall of the inner ring 8 also has a protruding bump 10. The bottom surface of the cover 11 has two concentric inner and outer rings. The inner ring has a slot for securing the bump 10. The outer ring fits between the inner and outer rings 8, 9 of the dial base 1.

[0025] The side of the cover 11 of the present invention protrudes to form a cover extension portion 12, and the outer side of the outer ring 9 of the dial base 1 protrudes to form a dial base extension portion 13.

[0026] The outer ring 9 of the present invention is provided with an overflow port 14 , so that if water enters between the outer ring 9 and the inner ring 8 , the water can be poured out through the overflow port 14 .

[0027] The dial base 1 of the present invention has an upwardly protruding middle portion of its upper end surface formed with an anti-overflow glue inner ring 15. The area enclosed by the anti-overflow glue inner ring 15 is provided with screw holes, through which screws are connected to and fixed to the connecting rod 5. When the present invention is used in a glue bucket, even if a small amount of glue overflows through the screw holes connected to the connecting rod 5, the anti-overflow glue inner ring 15 can limit it.

[0028] The upper end of the lid 11 of the present invention is raised to form a lid upper protrusion 20. There are multiple lid upper protrusions 20, which are evenly distributed. There is a lid upper protrusion 20 between each adjacent lid extension part 12, which can minimize the direct squeezing of external objects on the lid 11 and play a role in protecting the lid 11.

[0029] The bottom surface of the dial seat 1 of the present invention is protruded to form a dial seat lower limiting ring 16, and the dial seat lower limiting ring 16 has a limiting groove 17 protruding outward. The connecting rod 5 is T-shaped, and the protruding part of the connecting rod is embedded in the limiting groove 17, which can position the connecting rod 5.
