A center seat is provided at the center of the dial base, and the top end of the rotating shaft is inserted into the bottom limit of the center seat. The float can move up and down on the connecting rods and the rotating shaft, and the movement simultaneously rotates the rotating shaft.

[0008] Furthermore, the top of the center seat is provided with a pointer magnet and a pointer, and the top of the rotating shaft is provided with a rotating shaft magnet, and the rotating shaft magnet corresponds to the pointer magnet. When the rotating shaft rotates, the rotating shaft magnet rotates accordingly, thereby rotating the pointer magnet, and further realizing the pointer rotating accordingly.

[0009] Furthermore, the dial seat has an inner ring and an outer ring protruding from the upper end surface thereof, the center seat is located at the center of the inner ring, and the mounting hole is located outside the outer ring. The dial seat is fixed to the external box through the mounting hole.

[0010] Furthermore, the inner sidewall of the inner ring forms a step for accommodating the dial, and the inner sidewall of the inner ring protrudes to form a bump. The bottom surface of the lid has two concentric inner and outer rings. The inner ring has a groove for fixing the bump, and the outer ring is inserted between the inner and outer rings of the dial base. The design of the inner and outer rings improves the sealing between the lid and the dial base.

[0011] Furthermore, the middle portion of the upper end surface of the dial base is raised upward to form an anti-overflow glue inner ring, and the area surrounded by the anti-overflow glue inner ring is provided with a screw hole for connecting and fixing the connecting rod, thereby reducing the impact of glue overflow and protecting the pointer as much as possible.

[0012] Furthermore, the outer ring is composed of three separated arc-shaped parts, and an overflow port is formed between them to discharge the infiltrated water.

[0013] Furthermore, the connection between the lower limiting ring of the dial seat and the inner side wall of the threaded section can increase the strength of the lower limiting ring of the dial seat.

[0014] Furthermore, the side of the cover is protruded to form a cover extension, the outer side of the outer ring of the dial base is protruded to form a dial base extension, and the cover extension and the dial base extension are provided with corresponding screw holes, which can increase the convenience of installation between the cover and the dial base.

[0015] Furthermore, the dial seat extension is located at the overflow port between the arc-shaped portions of the outer ring, enabling quick positioning and assembly of the lid.

[0016] The beneficial effects of the utility model are: it can realize the rapid assembly of the connecting rod, and at the same time increase the strength of the assembly position of the connecting rod, thereby improving the installation stability of the dial seat.

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 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.

[0024] 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. The cover extension portion 12 and the dial base extension portion 13 are provided with corresponding screw holes, and the cover 11 is fixed to the upper end of the dial base 1 by screws.

[0025] The outer ring 9 of the present invention is composed of three separated arc-shaped parts, and an overflow port 14 is formed between them. If water enters between the outer ring 9 and the inner ring 8, the water can be discharged through the overflow port 14.

[0026] The dial seat extensions 13 of the present invention are three and are respectively located at the overflow ports between the three arc-shaped portions of the outer ring 9 .

[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 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.

[0029] The dial base 1 of the present invention has a hollow threaded section on its bottom surface with external threads for connecting to an external box. The dial base lower retaining ring 16 is located within the threaded section. The dial base lower retaining ring 16 is connected to the inner side wall of the threaded section to increase the strength of the dial base lower retaining ring 16.

[0030] Of course, the embodiments described above are only preferred examples of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
