In some embodiments of the present invention, as shown in fig. 1, fig. 2 and fig. 4, the inner wall of the adapter ring 20 is provided with an internal thread 21, the connection rod portion 11 of the sensor body 10 is provided with a thread section 111, the thread section 111 is provided with an external thread 112 adapted to the internal thread 21, and the sensor body 10 is screwed to the adapter ring 20.

When the sensor of this embodiment is installed, the adapter ring 20 is installed to the installation carrier, and then the connection rod portion 11 of the sensor body 10 is inserted into the adapter ring 20, until the threaded section 111 contacts the adapter ring 20, the sensor body 10 is rotated, so that the threaded section 111 is rotated to be stably connected with the adapter ring 20.

The adapter ring 20 is simple in connection structure with the sensor body 10, only the sensor body 10 needs to be rotated during assembly and disassembly, the assembly and disassembly operation is simple, and the use is convenient and flexible.

Of course, in other embodiments, the connecting rod 11 of the sensor body 10 may be connected to the adapter ring 20 by other connecting methods. For example, one of the adapter ring 20 and the connecting rod 11 is provided with a slot, and the other is provided with a buckle, and the slot and the buckle are matched to perform buckling connection. Or, for example, the inner wall of the adapter ring 20 is an elastic wall, and the outer diameter of the connecting rod part 11 is slightly larger than the inner diameter of the adapter ring 20, so that the connecting rod part 11 can be elastically inserted into the adapter ring 20, thereby realizing stable connection between the two.

The specific detachable connection between the adapter ring 20 and the connecting shaft 11 of the sensor body 10 is merely exemplary and should not be construed as being limiting.

In the exemplary embodiment, as shown in fig. 2 and 3, a threaded segment 111 is provided at the end of the connecting shaft portion 11 that is connected to the sensing head 12.

Like this, when installing sensor body 10 to adapter ring 20, rotatory sensor body 10 to connecting rod portion 11 and adapter ring 20 spiro union back fixed, response head 12 can remove to and offset with adapter ring 20 to carry out spacingly to the sensor in the installation depth of installation carrier, carry on spacingly to the position that sets up of response head 12 promptly.

During the in-service use, after the mounted position of adapter ring 20 is confirmed, the position that sets up of the response head 12 of sensor can be confirmed, conveniently installs the location, further reduces the installation degree of difficulty, improves the installation effectiveness.

In a specific embodiment, as shown in fig. 2 and 3, the adapter ring 20 has a width dimension along the axial direction of the connecting rod portion 11 that is smaller than the length dimension of the threaded section 111.

Therefore, the adapter ring 20 has a small structure, the connection area between the adapter ring 20 and the mounting carrier is reduced, and the abrasion to the mounting carrier when the adapter ring 20 is mounted is reduced. In addition, the spiro union area of contact between adapter ring 20 and the connecting rod portion 11 is less relatively, can reduce the frictional resistance between connecting rod portion 11 and the adapter ring 20 when rotatory installation sensor body 10 to because of avoiding turning resistance too big, lead to driving adapter ring 20 to rotate when rotatory dismouting sensor body 10, lead to adapter ring 20 pine to take off, thereby influence the installation stability and the reliability of whole sensor.
