SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a through-wall sealing mechanism for a sewage pipe, which can seal the joint of the sewage pipe and a sewage well and is convenient to install and arrange, aiming at the defects of the prior art.

In order to solve the technical problems, the utility model adopts the following technical scheme.

The utility model provides a sewage pipe through-wall sealing mechanism, its including cup joint in sleeve on the sewage pipe, be fixed with sealed cardboard on the sleeve, be equipped with sealed gasbag between the wall body of sealed cardboard and bilge well, the sleeve cooperates with the wall body joint of bilge well, be formed with annular cavity in the sealed gasbag, the outside of sealed gasbag be equipped with the suction nozzle that annular cavity is linked together, through the suction nozzle to when the air is poured into in the annular cavity, sealed gasbag takes place to expand and will the sewage pipe with the junction of wall body is sealed.

Preferably, the outer side wall of the sleeve is provided with an inverted buckle, and the inverted buckle is matched with a wall body of the sewage well in a clamping mode.

Preferably, the sealing clamping plate is provided with an air nozzle through hole, and the air inlet nozzle penetrates through the air nozzle through hole.

Preferably, a gap is formed between the sealing clamping plate and the wall body.

Preferably, the front end of the sleeve is provided with a retaining edge extending inwards, and an end face sealing ring is clamped between the retaining edge and the front end of the sewage pipe.

When the through-wall sewage pipe sealing mechanism disclosed by the utility model is installed, the sealing air bag and the sleeve with the sealing clamping plate are sequentially sleeved on the sewage pipe, the sleeve is fixedly matched with a wall body of a sewage well in a clamping manner, then air is injected into the annular cavity through the air inlet nozzle, the sealing air bag expands under the action of air pressure, and the joint of the sewage pipe and the wall body is sealed by using the sealing air bag in an expanded state.

Detailed Description

The utility model is described in more detail below with reference to the figures and examples.

The utility model discloses a sewage pipe through-wall sealing mechanism which is shown in a combined figure 1-4 and comprises a sleeve 4 sleeved on a sewage pipe 3, wherein a sealing clamping plate 1 is fixed on the sleeve 4, a sealing air bag 2 is arranged between the sealing clamping plate 1 and a wall body 5 of a sewage well, the sleeve 4 is in clamping fit with the wall body 5 of the sewage well, an annular cavity 20 is formed in the sealing air bag 2, an air inlet nozzle 21 communicated with the annular cavity 20 is arranged on the outer side of the sealing air bag 2, and when air is injected into the annular cavity 20 through the air inlet nozzle 21, the sealing air bag 2 expands and seals the joint of the sewage pipe 3 and the wall body 5.

When the structure is installed, the sealing air bag 2 and the sleeve 4 with the sealing clamping plate 1 are sequentially sleeved on the sewage pipe 3, the sleeve 4 is fixedly matched with a wall body 5 of a sewage well in a clamping mode, then air is injected into the annular cavity 20 through the air inlet nozzle 21, the sealing air bag 2 expands under the action of air pressure, and the joint of the sewage pipe 3 and the wall body 5 is sealed by the sealing air bag 2 in an expanded state.

In order to clamp and fix the sleeve 4, in this embodiment, an inverted buckle 40 is formed on the outer side wall of the sleeve 4, and the inverted buckle 40 is in clamping fit with the wall 5 of the sewage well. The clamping and fixing mode is convenient to install, and the clamping and fixing effect is stable and reliable.

In this embodiment, the sealing card board 1 is provided with an air nozzle through hole 10, and the air inlet nozzle 21 penetrates through the air nozzle through hole 10. The air nozzle through hole 10 is helpful to penetrate through the air inlet nozzle 21, so as to be conveniently connected with an air pump, in practical application, the air inlet nozzle 21 may be preset with a one-way valve, and of course, a manual valve may be directly arranged on the air inlet nozzle 21, regardless of which manner is adopted, and the utility model is within the protection scope of the utility model.

In practical application, the utility model provides a certain movement margin for the sealing clamping plate 1 so as to facilitate installation, and specifically, a gap 6 is arranged between the sealing clamping plate 1 and the wall 5.

In order to perform the end face sealing function, in this embodiment, the front end of the sleeve 4 is formed with a retaining edge 41 extending inward, and an end face seal ring 42 is interposed between the retaining edge 41 and the front end of the sewage pipe 3.

The sewage pipe through-wall sealing mechanism disclosed by the utility model utilizes the air pressure effect to drive the sealing air bag 2 to expand, so that the joint of the sewage pipe 3 and the wall body 5 is reliably sealed, the sewage is effectively prevented from seeping out between the sewage pipe and the wall body, and the anti-seepage effect is better realized.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents or improvements made within the technical scope of the present invention should be included in the scope of the present invention.
