[0026] like Figures 1 to 5 As shown, the embodiment of the utility model discloses a threading sealing device, which is arranged at the connection of different environmental levels to play a sealing role. Specifically, the threading sealing device includes the following structure:

[0027] A threading sealing device includes a sealing component 1 and an installation shaft 2. The installation shaft 2 has a cavity that passes through from top to bottom. The sealing component 1 is installed on one side of the cavity. The connecting end of the installation shaft 2 and the sealing component 1 is also provided with an equipment body. The sealing component 1 is fixed between the end of the cavity and the equipment body. The sealing component 1 is provided with a through hole for fixing a cable with a connector 3. The upper part of the sealing component 1 is an elastic member 11. The cable with a connector 3 is arranged in the through hole. The sealing component 1 is also provided with a locking component 4 for squeezing the elastic member 11 around. During the connection process between the locking component 4 and the sealing component 1, the size of the upper part of the sealing component 1 gradually increases, and gradually forms an interference fit seal with the cavity of the installation shaft 2. The two ends of the cable with a connector 3 are located in the Class A environment in the equipment body and separated from the Class B or Class C environment in the installation shaft 2.

[0028] In some specific embodiments, the sealing assembly 1 includes an elastic member 11 and a mounting plate 12, the elastic member 11 is provided with a first locking hole 13 and a threading hole 14, some of the threading holes 14 are provided with gaps communicating with the outside, so that the cable 3 with a connector can be directly plugged into the threading hole 14;

[0029] The mounting plate 12 is provided with a second locking hole 15 and a U-shaped notch 16 corresponding to the first locking hole 13 and the threading hole 14. The first locking hole 13 is a circular through hole, and the second locking hole 15 is a circular hole with internal threads arranged therein. The locking screw passes through the first locking hole 13 and the second locking hole 15 in sequence, and the cable 3 with connector is inserted into the threading hole 14 and connected to the U-shaped notch 16.

[0030] The diameter of the threading hole 14 is not greater than the wire diameter of the cable 3 with connector, and the gap is formed by cutting to ensure the sealing performance of the elastic member 11 .

[0031] In some specific embodiments, the locking assembly 4 includes a locking screw, and the upper connection of the locking screw with the sealing assembly 1, that is, the connection with the elastic member 11, is in the shape of an inverted truncated cone, and the smallest diameter is the same as the aperture of the first locking hole 13, and the lower part of the locking screw is provided with an external thread. After the locking screw is installed, the upper part thereof squeezes the first locking hole 13, so that an interference fit is formed between it and the mounting shaft 2, and the lower part thereof is screwed and connected with the second locking hole 15, so that the elastic member 11 and the mounting plate 12 are connected as a whole, and the elastic member 11 is prevented from being deformed downward under the squeezing of the locking screw, so as to further enhance the sealing performance of the elastic member 11.

[0032] In some specific embodiments, the size of the elastic member 11 is larger than the size of the mounting plate 12 to ensure the airtightness of the sealing assembly 1 .

[0033] In some specific embodiments, a mounting groove is provided at the connection between the mounting shaft 2 and the elastic member 11. The diameter of the mounting groove is larger than the diameter of the cavity to prevent the sealing assembly 1 from falling into the cavity when in use.
