In this embodiment, the threaded portion 30, the connecting portion 32, the stepped portion 34, and the measuring head 31 are all columnar and have diameters that decrease in order.

As shown in fig. 3, the adaptor 5 includes an inner hole 50 for mounting the sensor 3, and the inner hole 50 is composed of three communicating holes, namely, a mating hole 51 for mating with the threaded portion 30 of the sensor 3, a communicating hole 52 for passing the measuring head 31 therethrough, and an adaptor hole 53 between the mating hole 51 and the communicating hole 52. The transfer hole 53 is for receiving the connection part 32. The diameters of the coupling hole 51, the transit hole 53, and the communication hole 52 are sequentially reduced, and a first step 54 is formed between the transit hole 53 and the communication hole 52.

To increase the seal, the sensor mounting assembly further includes a first seal ring 6 disposed between the bottom of the connecting portion 32 and the first step 54, as shown in fig. 4. The first seal ring 6 is sleeved on the step part 34, and the inner diameter of the first seal ring is tightly matched with the step part 34.

As shown in fig. 3, 5 and 6, a convex connecting block 55 is disposed at the top end of the adapter 5, at least one through hole 56 is disposed on the connecting block 55, a screw hole 70 matching with the through hole 56 is disposed on the mounting portion 7, and the adapter 5 can be fixed on the mounting portion 7 by inserting a fastener such as a bolt or a screw through the through hole 56 and matching with the screw hole 70. The plane 550 with the through hole 56 can sink, so that the interference between the head of the bolt and the sensor 3 is avoided when the sensor 3 is installed at the later stage.

As shown in fig. 4, the mounting portion 7 is provided with a mounting hole 74 for mounting the adapter 5, and the mounting hole 74 is matched with the shape of the adapter 5. In this embodiment, the adapter 5 is provided with a first shaft portion 57 and a second shaft portion 58 on the outside, and the diameter of the first shaft portion 57 is larger than that of the second shaft portion 58, so as to form a second step 59; correspondingly, a first bore section 71 associated with the first shaft section 57 and a second bore section 72 associated with the second shaft section 58 are provided in the mounting bore 74, respectively, forming a third step 73.
