Figure 4 This is a three-dimensional diagram of the connection frame structure of an immersion liquid level meter in an embodiment of the utility model. The immersion liquid level meter includes a meter head 1 and a connection block 2. A limit assembly is installed on the connection block 2, and a clamping assembly is installed on the meter head 1.

[0023] In this embodiment, the limiting assembly includes a detection head 3 fixedly installed on the bottom of the connecting block 2, connecting frames 4 are fixedly installed on both sides of the connecting block 2, telescopic springs 5 ​​are fixedly installed inside the two connecting frames 4, and slides 6 are fixedly installed on the opposite side of the two telescopic springs 5. The interiors of the two connecting frames 4 are provided with sliding grooves, and the slides 6 are slidably connected to the connecting frames 4 through the sliding grooves, providing guidance for the movement and storage of the limiting rod 7, making the movement and storage of the limiting rod 7 more convenient.

[0024] Among them, the limiting rods 7 are fixedly installed on the opposite sides of the two slides 6, a through hole is opened inside the filter frame 9, and a plug-in hole is opened inside the connecting block 2. The limiting rod 7 is plugged with the limiting rod 7 through the through hole and the plug-in hole, which is convenient for fixing the filter frame 9 inside the connecting block 2, and is convenient for protecting the detection head 3 when the detection head 3 is in use, thereby reducing the possibility of damage to the detection head 3 during detection.

The L-shaped pull rod 8 extends to the outside of the connecting frame 4 through the first extension hole, which is convenient for the user to pull the two L-shaped pull rods 8, thereby achieving the purpose of adjusting the limit rod 7.

[0026] In addition, a filter frame 9 is plugged into the bottom of the connection block 2 , and a plug-in slot is provided at the bottom of the connection block 2 . The filter frame 9 is plugged into the connection block 2 through the plug-in slot, so as to initially limit the filter frame 9 inside the connection block 2 .

[0027] A sealing ring 10 is fixedly installed on the outer side of the two L-shaped pull rods 8, and the sealing ring 10 fits with the first extension hole to prevent liquid from penetrating into the connecting block 2 from the first extension hole when the device is in use, thereby increasing the service life of the detection head 3.

[0028] It should be noted that the utility model facilitates the rapid installation and disassembly of the filter frame 9 by installing a limiting component. After the filter frame 9 has been used for a long time, the filter frame 9 is disassembled and cleaned to prevent impurities from adhering to the inside of the filter holes, thereby affecting the efficiency of the detection head 3 and improving the quality of the use of the device.

[0029] Specifically, when in use, the L-shaped pull rod 8 is pulled to both sides and moved in opposite directions, driving the slide plate 6 to move synchronously, so that the two telescopic springs 5 ​​are compressed, and then driving the two limit rods 7 to move, so that the limit rods 7 are moved out from the inside of the connecting block 2 and the filter frame 9, and then the filter frame 9 is easily pulled out from the bottom of the connecting block 2, and then the filter frame 9 is cleaned to prevent impurities from sticking to the inside of the filter hole, thereby affecting the efficiency of the detection head 3 and improving the quality of the device.

[0030] In this embodiment, the clamping assembly includes a fixed plate 11 fixedly mounted on the bottom of the meter head 1, an electric cable 12 fixedly connected to the connecting block 2 is arranged at the bottom of the fixed plate 11, and an installation frame 13 is fixedly mounted on the bottom of the fixed plate 11.

[0034] Specifically, when in use, the two bolts 14 are rotated with the help of a tool, thereby driving the clamp 15 to rotate synchronously, thereby fixing and clamping the connection between the cable 12 and the connecting column, reducing the possibility of the cable 12 falling off the connecting column, and improving the use quality of the device.

[0035] The working principle of the above embodiment is as follows: when in use, the L-shaped pull rod 8 is pulled to both sides to move in opposite directions, driving the slide plate 6 to move synchronously, so that the two telescopic springs 5 ​​are compressed, and then driving the two limit rods 7 to move, so that the limit rods 7 are moved out from the inside of the connecting block 2 and the filter frame 9, thereby facilitating the extraction of the filter frame 9 from the bottom of the connecting block 2, and then cleaning the filter frame 9 to prevent impurities from adhering to the inside of the filter hole, thereby affecting the efficiency of the detection head 3 and improving the quality of the use of the device. When in use, the two bolts 14 are rotated with the help of a tool, thereby driving the clamp 15 to rotate synchronously, thereby fixing and clamping the connection between the cable 12 and the connecting column, reducing the possibility of the cable 12 falling off the connecting column, and thereby improving the quality of the use of the device.
