[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A retractable tuning fork liquid level switch mounting bracket shown in the figure comprises a tuning fork liquid level switch mounting bracket body 1 and a tee 2 for connecting a crane pipe, a tuning fork liquid level switch 3 is axially threadedly fixed on one end of the tuning fork liquid level switch mounting bracket body 1, the connecting crane pipe comprises an elbow 4 fixedly mounted on an assembly pipe at the upper end of the tee 2 and a steel pipe 6 fixedly connected to the elbow 4 through a three-piece ball valve 5, a rotary joint 7 is arranged at the left end of the steel pipe 6, a first threaded reducer 8, a second threaded reducer 9, a quick connector 10 and a sealing connector 11 are axially sleeved on the outer side surface of the tuning fork liquid level switch mounting bracket body 1, and 31 scratches 12 are engraved on the straight section of the tuning fork liquid level switch mounting bracket body 1.

[0022] The sealing joint 11 and the first thread reducer 8 are connected by threads.

[0023] The total length of the scratches 12 on the tuning fork liquid level switch mounting frame body 1 is 300 mm, and the sealing joint 11 is composed of a threaded joint 111 , a nut 112 , and two rubber seals 113 .

[0024] The first thread reducer 8 and the second thread reducer 9 are respectively welded and fixed on both sides of the tee 2, and the quick connector 10 and the second thread reducer 9 are fixed by thread connection.

[0025] A joint groove is provided between the two rubber seals 113 of the sealing joint 11, and the two rubber seals 113 of the sealing joint 11 are arranged inside the nut 112. When the nut 112 rotates in the direction of the threaded joint 111, the two rubber seals 113 are compressed and tightened, pressing the tuning fork liquid level switch mounting frame body 1, and the tuning fork liquid level switch mounting frame body 1 is fixed. On the contrary, the tuning fork liquid level switch mounting frame body 1 can move to the left, so as to achieve the purpose of moving the liquid level meter probe.

[0026] principle:

[0027] The vertical pipe is connected to the tank car through a quick connector 10. The sealing performance of the quick connector 10 can reach the safety level. The tuning fork level switch mounting frame body 1 is connected to the crane pipe through a tee 2. The tuning fork level switch mounting frame body 1 consists of a connector and a section of horizontal pipe. Figure 3One end of the joint is threaded, and the other end is welded to the cross tube. 31 scratches 12 are engraved on the 300mm straight section on the cross tube, which can be used by the owner to mark the full liquid level of tank trucks of different tonnages. The tuning fork level switch 3 and the tuning fork level switch mounting frame body 1 are connected together by threads, and then the installation height of the level switch is adjusted by the sealing joint 11. The sealing joint 11 controls the tightness of the two rubber seals 113 by rotating the nut 112, thereby realizing the movement of the tuning fork level switch mounting frame body 1, and adjusting the installation height of the tuning fork level switch 3. This mounting frame realizes that when the crane pipe is operated, the tuning fork level switch can not only adjust the installation height, but also achieve the sealing of the loading process, making the operating environment safer and more reliable.
