When the angle of the ultrasonic liquid level meter needs to be adjusted, the screw rod can be rotated, the push plate is limited by the limiting rod, so it can be moved, the push plate is in contact with the surface of the ultrasonic liquid level meter, and it is extruded. Because the rubber thread ring has a certain elasticity, the ultrasonic liquid level meter can be moved to fine-tune the angle, so that the ultrasonic liquid level meter reaches the required emission angle, thereby reducing the uneven reflection of the ultrasonic wave beam and facilitating adjustment.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a liquid level measuring device, comprising a tank body, a fixing frame and an ultrasonic liquid level meter, the fixing frame is fixedly connected to the surface of the tank body, the inside of the fixing frame is communicated with the inside of the tank body, the inside of the fixing frame is provided with a buffer sleeve, the inside of the fixing frame is fixedly connected with a rubber thread ring, the surface of the ultrasonic liquid level meter is threadedly connected with the rubber thread ring, the surface of the fixing frame is threadedly connected with a plurality of screw rods, the screw rod is movably penetrated and extends to the inside of the fixing frame, and one end of the screw rod is rotatably connected with a push plate.
[0006] Further, the inside of the buffer sleeve is provided with a conical hole, and the push plate is provided in an arc shape.
[0007] Further, the push plate is fixedly connected with a limiting rod at one end corresponding to the threaded rod, and the limiting rod is movably penetrated and extends to the outside of the fixing frame.
[0008] Compared with the prior art, the utility model has the advantages of:
[0009] 1. When the angle of the ultrasonic liquid level meter needs to be adjusted, the screw rod can be rotated, the push plate is limited by the limiting rod, so it can be moved, the push plate is in contact with the surface of the ultrasonic liquid level meter, and it is extruded, so the ultrasonic liquid level meter can be moved to finely adjust the angle, so that the ultrasonic liquid level meter reaches the required emission angle, thereby reducing the unevenness of ultrasonic beam reflection, and facilitating adjustment.
[0010] 2. By arranging the tapered hole of the buffer sleeve, the ultrasonic liquid level meter can be closely attached to the surface when it enters the fixed frame, thereby playing a buffering and sealing role. By arranging the rubber thread ring, when the vehicle travels on a rugged road, the rubber thread ring can absorb part of the vibration energy, and the impact on the ultrasonic liquid level meter plays a protective role.
