fig. 2 is another schematic diagram of the sealing structure of the ground drainage pipeline for the building.

Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

As shown in fig. 1 and fig. 2, the sealing structure of the ground drainage pipeline for the building, the drainage pipeline comprises a pipe joint 2 vertically inserted on the ground 1 of the building, and the lower end 21 of the pipe joint 2 is connected with a water outlet pipeline (not shown in the figure). The pipe joint also comprises an inner pipe component 3 which is led out upwards from the inside of the pipe joint 2, and a sealing component 6 which is used for sealing a gap between the inner pipe component 3 and the upper end 22 of the pipe joint 2; the building structure further comprises an enclosure assembly 9 which is sleeved on the inner pipe assembly 3 and seals an upper section 20 of the pipe joint 2 protruding out of the building ground 1 in a preset space 10. By means of the sealing assembly 6 and the enclosure assembly 9, the portion of the pipe joint 2 exposed to the ground of the building can be effectively sealed, thereby effectively preventing the odor in the drain line from overflowing.

In the sealing structure of the ground drainage pipeline for the building, the inner pipe assembly 3 has an outstanding upper end 31 of the pipe joint 2. The sealing cover assembly 9 includes a semi-spherical (having an inner space) sealing cover 91 and a pressing hoop 92, the sealing cover 91 is inserted from the end of the upper end 31 and covers the part of the upper section 20 of the pipe joint 2 protruding from the building floor. Meanwhile, the pressing hoop 92 is mounted on the upper end 31 in a combining manner, and is pressed downwards against the sealing cover 91 by the action of external force, so that the lower edge 93 of the sealing cover 91 is attached to the building floor 1, that is, a relatively closed space is formed with the building floor 1 by the action of the lower pressure, so as to prevent the odor in the pipe joint 2 from overflowing.

In the sealing structure of the ground drainage pipeline for the building, the inner pipe assembly 3 comprises an inner pipe 32 and an expansion sleeve 4 arranged outside the inner pipe 32. The sealing assembly 6 comprises a rotary sealing sleeve 61 which is rotatably clamped at the upper end part of the pipe joint 2 and a sealing gasket 62 arranged in the rotary sealing sleeve 61, and the rotary sealing sleeve 61 is in threaded connection with the inner pipe 32. Specifically, four protruding clamping columns 23 are uniformly distributed on the outer wall of the upper end 22 of the pipe joint 2 along the circumferential direction. Correspondingly, an inward-concave clamping rib 63 is arranged on the lower edge of the rotary sealing sleeve 61, and four bayonets 64 corresponding to the clamping columns 23 are formed in the clamping rib 63. Thus, the bayonet 64 of the rotating sealing sleeve 61 is aligned with the latch 23 so as to be inserted into the upper end 22 of the pipe joint 2, and when the rotating sealing sleeve is further driven by external force to rotate, the latch 23 and the bayonet 64 are misaligned, so that the clamping rib 63 of the rotating sealing sleeve 61 is clamped by the latch 23 and is not separated from the upper end 22 of the pipe joint 2. Moreover, when the rotating sealing sleeve 61 is driven to rotate by external force (i.e. the state shown in fig. 1 is changed to the state shown in fig. 2), the inner tube 32 is driven to move upwards and press the end 41 of the expansion sleeve 4 (i.e. the end of the inner tube 32 is provided with the protruding bulge 33, and the end 41 of the expansion sleeve 4 is provided with three separate latch shapes, so that when the inner tube 32 moves upwards, the expansion sleeve 4 cannot move upwards due to the abutting of the rotating sealing sleeve 61, and the end 41 is pressed by the bulge 33 at the end of the inner tube 32 to expand), so that the end 41 of the expansion sleeve 4 blocks the gap between the inner wall of the lower end 21 of the pipe joint 2 and the outer wall of the lower end of the inner tube 32. At the same time, the gasket 62 also seals the gap between the upper end 22 of the pipe joint 2 and the upper end of the inner pipe 32.

While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
