[0024] First embodiment:

[0025] This embodiment discloses a detachable proximity switch base.

[0026] A detachable proximity switch base is used for container 1, which has a hollow structure. For example, in this embodiment, container 1 is a cylinder body, and two sets of detachable proximity switch bases are provided on the side of the cylinder body. The proximity switches 3 in the detachable proximity switch bases detect the liquid level in the rod-side chamber and the rodless chamber inside the cylinder body, respectively.

[0027] The detachable proximity switch base includes a first cylinder 2, a proximity switch 3, and a nut 4. The first cylinder 2 is threaded to the side of the container 1, and its interior communicates with the interior of the container 1. For example, the first end is closer to the container, and the second end is farther from the container. A second cylinder 11 is also provided on the outside of the container 1, and its interior communicates with the interior of the container 1. The first end of the outer side of the first cylinder 2 is threaded into the interior of the second cylinder 11. Specifically, the second cylinder 11 is perpendicular to the outer surface of the container 1 for ease of design and manufacturing.

[0028] The first end of the proximity switch 3 is threaded into the first cylinder 2, and the first end of the proximity switch 3 has a sensing end 31. The nut 4 is threaded into the second end of the proximity switch 3, and is screwed in until the first end of the nut 4 presses against the second end of the first cylinder 2.

[0029] Furthermore, a column 21 extends from the outer side of the first cylinder 2, and the column 21 is coaxially arranged with the first cylinder 2. The first cylinder 2 is screwed into the second cylinder 11, and the first end of the column 21 presses against the second end of the second cylinder 11 to ensure that the first cylinder 2 is screwed in properly.

[0030] Furthermore, the detachable proximity switch base also includes a third cylinder 6, which is threaded to the second end of the outer side of the first cylinder 2. The first end of the third cylinder 6 presses against the second end of the column 21 to ensure that the third cylinder 6 is screwed into place. The second end of the proximity switch 3 is provided with a socket, which is located inside the third cylinder 6. Preferably, the second end of the third cylinder 6 is higher than the second end of the proximity switch 3 to protect the proximity switch 3 from damage.

[0031] Furthermore, a stepped hole 22 is provided on the inner side of the first cylinder 2, and a stepped portion 32 is provided on the outer surface of the proximity switch 3, which facilitates confirmation that the proximity switch 3 is screwed into the first cylinder 2 in place, while ensuring the sealing effect of the threaded connection.

[0032] Furthermore, an annular groove 33 is formed at the first end of the outer side of the proximity switch 3, and a sealing ring 34 is fitted on the outer side of the annular groove 33 to further improve the sealing effect between the proximity switch 3 and the first cylinder 2.

[0033] Furthermore, the detachable proximity switch base also includes a signal line 5, the end of which has a quick-connect plug 51. The quick-connect plug 51 extends into the third cylinder 6 and is plugged into the socket, facilitating the insertion and removal of the signal line 5 while protecting the quick-connect plug 51.

[0034] In this embodiment, the first cylinder 2 is threaded to the side of the container 1, the first end of the proximity switch 3 is threaded to the inside of the first cylinder 2, and finally the nut 4 is threaded to the second end of the proximity switch 3 until the first end of the nut 4 presses against the second end of the first cylinder 2, thereby locking the proximity switch 3. The tension of the proximity switch 3 by the nut 4 is in the same direction as the liquid leakage in the container 1, ensuring a secure installation and good sealing.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
