As shown in fig. 1 to fig. 4, the utility model discloses a disconnect-type seal structure, include: a housing 10, and a sealing assembly 20 connected to the housing 10; the sealing assembly 20 comprises a pressure plate 21, a top cover 22 and an elastic sealing ring 23; the pressing plate 21 is connected with the top cover 22, the pressing plate 21 is located above the top cover 22, and the elastic sealing ring 23 is arranged between the pressing plate 21 and the top cover 22.

As shown in fig. 1 to 4, the sealing assembly 20 is embedded inside the housing 10, so that space is saved and sealing performance is improved.

In the present embodiment, the pressing plate 21 and the top cover 22 are connected by a plurality of screws 24, the position between the pressing plate 21 and the top cover 22 is adjusted by screwing the screws 24, the elastic sealing ring 23 is adjusted to be in a relaxed or compressed state, when the screws 24 are not screwed, the elastic sealing ring 23 is in the relaxed state without any compression or stretching, the pressing plate 21 and the top cover 22 can be easily placed in the housing 10, and the friction force between the elastic sealing ring 23 and the inner wall of the housing 10 is small; when the screw 24 is tightened, the pressure plate 21 and the top cover 22 approach each other under the action of the screw 24 to press the elastic sealing ring 23, the elastic sealing ring 23 is compressed up and down and extended towards two sides, but because the elastic sealing ring 23 is already contacted with the inner wall of the shell 10, the elastic sealing ring 23 can only extend towards the sealing surface of the pressure plate 21 and is finally compressed into a shape close to a rectangle, the friction force between the elastic sealing ring 23 and the inner wall of the shell 10 is increased, the pressure plate 21 and the top cover 22 are prevented from sliding downwards, and therefore the sealing effect is achieved.

Further, in this embodiment, the number of the screws 24 is greater than or equal to 4, and the specific number may be set according to actual needs to meet different application scenarios.

As shown in fig. 2 to 4, a groove 211 is formed in the bottom of the pressing plate 21, and the elastic sealing ring 23 is embedded in the groove 211, so that the space is saved, the elastic sealing ring is not easy to loosen, and the elastic sealing ring is not easy to shift when deformed.

As shown in fig. 1 to 4, a guide portion 11 is further provided on an inner side of an upper end of the housing 10 to facilitate the insertion or removal of the sealing assembly 20.

The housing 10 is cylindrical, and may be in other shapes, and the specific shape may be set according to actual needs to meet different application scenarios.

The pressing plate 21, the top cover 22 and the elastic sealing ring 23 are all circular to adapt to the shape of the shell 10, so that a better sealing effect is achieved.

In the present embodiment, the outer diameter of the elastic sealing ring 23 is larger than the outer diameter of the pressure plate 21, so that the elastic sealing ring 23 has a space for deformation.

The utility model changes two parallel surfaces of the traditional integrated sealing structure to compress the sealing ring to extend in two directions into a separated sealing structure, after the sealing ring is locked and extruded by the screw, the sealing ring is contacted and extruded with a third surface, the sealing ring is deformed and extends only in one direction, thereby achieving the sealing effect, when the screw does not lock two parallel surfaces, the sealing ring has no compression deformation, so the friction force is very small, and the disassembly and the assembly can be easily carried out; when the screw is screwed down, the sealing ring is compressed and deformed to fill the groove, and the friction force between the sealing ring and the sealing surface is increased, so that the sealing effect is achieved.

The above-mentioned embodiment is the utility model discloses the implementation scheme of preferred, in addition, the utility model discloses can also realize by other modes, any obvious replacement is all within the protection scope of the utility model under the prerequisite that does not deviate from this technical scheme design.
