Abstract
Description
Technical Field
[0001] The utility model specifically relates to a multi - seal mechanism for penetrating a cabin. Background Technique
[0002] The interior of a sealed container often requires external - inserted cables for power supply. However, currently, when the cable is at the socket, it will be soaked due to external humidity and then enter the sealed container, affecting the use inside the sealed container and reducing the sealing effect. Content of the Utility Model
[0003] The purpose of the utility model is to provide a multi - seal mechanism for penetrating a cabin to solve the problems raised in the above - mentioned background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A multi - seal mechanism for penetrating a cabin, including a communication cable. The communication cable is inserted into the container through a preset jack on the surface of the container. An inner watertight joint is arranged at one end of the communication cable inside the container cavity, an outer watertight joint is arranged at one end of the communication cable outside the container, and a double - headed interface is arranged on the outer side of one end of the communication cable inside the jack.
[0005] Preferably, on the communication cable, and successively between the inner watertight joint and the inner wall of the container cavity, a thin nut and a washer are arranged.
[0006] Preferably, the gap between the communication cable and the jack is filled with sealant, and a gasket is arranged at the filling port.
[0007] Preferably, the gasket is located on the lower surface of the washer.
[0008] Preferably, on the outer side of one end of the communication cable outside the container, a U - shaped special ring and a first O - ring are successively arranged.
[0009] Preferably, a second O - ring is arranged on the outer side of the double - headed interface.
[0010] The technical effects and advantages of the utility model: For this multi - seal mechanism for penetrating a cabin, the cavity adopts a multi - seal type. Between the external flange planes, a multi - mechanical seal ring axial pressure seal is adopted, and the radial gap is filled with a high - strength and high - toughness customized liquid - solid sealant. After filling, the inner cavity nut is locked and cured at room temperature to achieve the optimal sealing effect. As a whole, due to the axial and radial seals, it meets the sealing requirements under high - pressure environments, truly realizes zero leakage, and the overall filled colloid has stable elastic properties, and the compressive performance is better exerted.
