Description

Technical Field

[0002] A level meter is an instrument used to measure the height of liquid or solid materials in a container or pipe. There are many types of level meters. The magnetic float level meter is one of them. The magnetic float level meter is a common level measurement device that uses the buoyancy and magnetism of the float to measure the liquid level. This type of level meter usually consists of a float, a catheter, and a sensor. The float usually contains magnetic material inside. When the float moves up and down with the change of the liquid level, the sensor detects the position of the float and converts the corresponding signal into the liquid level.

[0003] The utility model patent with authorization announcement number: CN216815689U discloses a magnetic float level gauge, involving a liquid level shell, a heating ring is fixed inside the liquid level shell, a heating wire is wound inside the heating ring, an insulation ring is fixed inside the heating ring, a detection float is slidably connected inside the insulation ring, an end cover is connected to the top of the liquid level shell by a thread, a connecting pipe is connected to the outside of the liquid level shell, a flange is fixed on the side of the connecting pipe away from the liquid level shell, and a fastening frame is fixed on the side of the liquid level shell away from the connecting pipe; the utility model arranges a heating wire inside the liquid level shell, so that the liquid can be heated in a cold environment, and the heating effect is better through the winding method, thereby achieving the effect of accurately monitoring the liquid level in a cold environment, and at the same time, by arranging a fill light, employees can still read the readings accurately even in poor light conditions.

However, the liquid level shell is exposed when in use, and is prone to breakage, damage or tilt when hit by external objects or workers. When the liquid level shell encounters the above situation, it may not be used smoothly or errors may occur, thereby reducing the accuracy of the liquid level meter. Utility Model Content

[0031] See also Figure 1-7 : The outer side of the slide rod 62 is connected to a limiting plate 72, a limiting groove 71 is provided on one side of the first protective plate 551, and the limiting groove 71 is communicated with the slide groove 61, the limiting plate 72 is arranged on the inner side of the limiting groove 71, the slide rod 62 can be connected to the limiting plate 72, and the first protective plate 551 can limit the limiting plate 72 through the limiting groove 71, and realize the restriction of the slide rod 62, so that when the slide rod 62 moves, it is not easy to rotate due to the connection between itself and the slide groove 61, thereby reducing the possibility of the slide groove 61 being offset and rotating, and increasing the stability of the slide rod 62 when in use.

[0032] See also Figure 1-6 : A fixed ring block 8 is connected to one end of the slide rod 62, and the fixed ring block 8 is arranged on the side of the slide rod 62 away from the connecting plate 63. The diameter of the fixed ring block 8 is larger than the diameter of the slide rod 62. The slide rod 62 can be connected to the fixed ring block 8, and the fixed ring block 8 can limit the slide rod 62 by having its own diameter larger than the diameter of the slide rod 62, so that the slide rod 62 is not easy to slide out from the inner side of the slide groove 61 when being pulled or pushed, thereby further increasing the stability of the slide groove 61 when in use.
