Description

Technical Field

[0001] The present application relates to the technical field of liquid level transmitters, and in particular to a liquid level transmitter with an anti-theft function. Background Art

[0002] A level transmitter is an instrument used to measure the liquid level in a liquid container. It can convert the measured liquid level information into an electrical signal output. This device is very important in many industrial applications, such as in the chemical, pharmaceutical, water treatment and food processing industries.

The anti-theft component is provided with a touch switch and an alarm. Whenever a non-professional person turns the bolt to disassemble the flange, the alarm sounds an alarm. However, the alarm alone cannot effectively prevent the further disassembly, so that the transmitter is still likely to be disassembled. Therefore, a liquid level transmitter with an anti-theft function is designed to solve the above-mentioned problem. Utility Model Content

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a liquid level transmitter with an anti-theft function. Figure 1-3 , a liquid level transmitter with anti-theft function, including a transmitter body 1, a mounting plate 2 is fixedly installed at the lower end of the transmitter body 1, a mounting hole is opened on the mounting plate 2, and a bolt 3 is connected to the thread in the mounting hole, and a protective frame 4 is inserted at the upper end of the bolt 3, and the protective frame 4 is used to cover the upper end of the bolt 3 to protect the bolt 3, so as to prevent the bolt 3 from being directly exposed to the outdoors and prolong the service life, and the upper end of the protective frame 4 is fixedly connected to the plug block 5, and the upper end of the plug block 5 is plugged into the fixed frame 6, and the maximum rotation angle of the fixed frame 6 is ninety degrees, so that the fixed frame 6 can rotate within a certain range, so that the plug block 5 at the lower end can be inserted into the fixed frame 6 for connection, and the upper end of the fixed frame 6 is rotatably connected to the fixed plate 7, and the fixed plates 7 are rotatably connected to the mounting ring 8 on one side close to each other, and the fixed plate 7 is used to connect four fixed frames 6 to the mounting ring 8 together, so as to simultaneously control the position adjustment of the fixed frame 6;

[0021] By adopting the above technical solution, the internal thread of the mounting ring 8 is connected to the threaded ring 9, and the threaded ring 9 is rotatably connected to the transmitter body 1. The threaded ring 9 is rotated and the mounting ring 8 is held by hand. The rotation of the threaded ring 9 drives the mounting ring 8 to descend, which is convenient for controlling the connected fixed frame 6 and the fixed plate 7.

[0022] By adopting the above technical solution, the protection frame 4 is hexagonal, such as Figure 1 As shown, the protection frame 4 is matched with the upper end of the bolt 3 to facilitate protection of the bolt 3.

[0023] By adopting the above technical solution, in order to facilitate the limiting of the protective frame 4 so that the protective frame 4 cannot rotate, and thus the bolt 3 cannot be rotated and disassembled, a fixing groove is also opened on the side of the plug block 5, and an elastic sheet 51 is fixedly connected in the fixing groove, and the elastic sheet 51 is fixedly connected to the clamping block 52 on the side away from the inner wall of the fixing groove, and an installation groove 61 is opened in the fixing frame 6, and the installation groove 61 clamps the clamping block 52.

[0024] By adopting the above technical solution, one side of the installation groove 61 is slidably connected to the stopper 62, and a socket is opened on one side of the stopper 62. When disassembling, the stopper 62 on one side can be pushed to make the stopper 62 push the card block 52 on one side located in the installation groove 61 into the fixed groove, so that the plug-in block 5 is no longer engaged with the fixed frame 6, and the fixed frame 6 can rise and separate from the plug-in block 5.

[0025] The implementation principle of the liquid level transmitter with anti-theft function in the embodiment of the present application is as follows: the mounting plate 2 of the transmitter body 1 is mounted on the side of the container and fixed with bolts 3 to fix the transmitter body 1, and then the protection frame 4 is inserted from the upper end of the bolts 3 to cover the bolts 3 to protect the bolts 3. After installation, the threaded ring 9 is rotated, and the mounting ring 8 is held by hand. The threaded ring 9 rotates to drive the mounting ring 8 to descend, so that the mounting ring 8 drives the fixing plate 7 on one side to descend, and the fixing plate 7 drives the fixing frame 6 to descend. The fixing plate 7 can also be rotated during the descent, so that the fixing plate 7 drives the fixing frame 6 to rotate. , so that the position of the fixed frame 6 after rotation is located at the upper end of the protection frame 4, and the mounting ring 8 continues to descend, so that the fixed frame 6 descends and the plug block 5 is inserted into it. Since the bolts 3 are in different positions when being screwed, the fixed frame 6 may be misaligned with the plug block 5 when it descends. At this time, the fixed frame 6 can be rotated to the same angle as the plug block 5 and then continue to descend, so that the fixed frame 6 can be plugged into the plug block 5; after the plugging, the elastic sheet 51 in the fixed groove, which is aligned with the mounting groove 61 on one side of the plug block 5, drives the clamping block 52 to move, so that the clamping block 52 clamps the mounting groove 61, thereby completing the fixation.
