DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 The utility model is described in further detail.

[0023] The utility model embodiment discloses a wall-penetrating casing plugging structure, referring to Figure 1-2 , including a wall 1, and a pre-buried casing 2 embedded in the wall 1, a pipe 3 is passed through the pre-buried casing 2, and people can pass the pipe 3 of lines such as wires and cables through the pre-buried casing 2 for routing.

[0024] Reference Figure 1-2 A water stop ring 21 embedded in the wall 1 is provided in the middle of the outer wall of the embedded sleeve 2. The embedded sleeve 2 and the water stop ring 21 are buried together when the wall 1 is poured. The embedded sleeve 2 is used to seal the pipeline 3, and the water stop ring 21 is used to ensure the waterproofness of the embedded sleeve 2 itself. The water stop ring 21 is a public technology and will not be described in detail here.

[0025] Reference Figure 1-2 The internal threads at both ends of the embedded sleeve 2 are provided with sealing glands 4 for sealing the connection between the embedded sleeve 2 and the pipeline 3. People can rotate the sealing gland 4, and under the threaded connection of the embedded sleeve 2, screw the sealing gland 4 into the two ends of the embedded sleeve 2 to preliminarily seal the connection between the embedded sleeve 2 and the pipeline 3.

[0026] Reference Figure 2-4 A positioning ring 23 is fixedly provided on the inner wall of both ends of the embedded sleeve 2, and a first sealing ring 24 is fixedly provided on one side of the positioning ring 23. A tapered hole 41 is opened at one end of the blocking gland 4 for guiding and squeezing the first sealing ring 24 to the connection between the positioning ring 23 and the pipeline 3 through the top pressure when the blocking gland 4 rotates. After one end of the blocking gland 4 is screwed into the embedded sleeve 2, the end of the tapered hole 41 of the blocking gland 4 will contact the first sealing ring 24, and with the continuous rotation of the blocking gland 4 and the inclined surface guidance of the tapered hole 41, the first sealing ring 24 is tightly pressed against the connection between the positioning ring 23, the pipeline 3 and the blocking gland 4, thereby blocking and sealing the connection between the pipeline 3, the embedded sleeve 2 and the blocking gland 4.

[0027] Reference Figure 2 and Figure 4 The inner walls of the positioning ring 23 and the embedded sleeve 2 are in contact with the outer wall of the pipe 3 , and the positioning ring 23 and the embedded sleeve 2 can support and limit the pipe 3 .

[0028] Reference Figure 2 and Figure 4 The outer walls at both ends of the embedded sleeve 2 are fixed with wing discs 22 respectively embedded in the two sides of the wall 1, and one side of the wing disc 22 is in contact with the outer wall of the embedded sleeve 2. The embedded sleeve 2 can contact the embedded sleeve 2 through the wing disc 22. The embedded sleeve 2, the water stop ring 21 and the wing disc 22 constitute a wall-penetrating sleeve.

[0029] Reference Figure 2-4 A sealing mechanism is provided between the wall 1, the embedded sleeve 2 and the plugging gland 4, and the sealing mechanism includes a sealing groove 42 opened between the wall 1, the wing disc 22 and the plugging gland 4, and a second sealing ring 43 fixedly provided on one side of the plugging gland 4 for filling the sealing groove 42. By pressing the second sealing ring 43 when the plugging gland 4 rotates, the second sealing ring 43 can be tightly pressed in the sealing groove 42 to seal the connection between the wall 1, the embedded sleeve 2 and the plugging gland 4, thereby further sealing the two ends of the wall sleeve. The first sealing ring 24 and the second sealing ring 43 are both existing rubber sealing rings, and the usage is small, thereby reducing rubber consumption and saving materials.

[0030] Reference Figure 1 , Figure 2 and Figure 4An iron handle 5 for people to hold is rotatably provided on one side of the sealing gland 4, and the outer wall of the iron handle 5 is coated with anti-rust paint. A magnet 51 for magnetically fixing the iron handle 5 is fixed on one side of the sealing gland 4. People can drive the sealing gland 4 to rotate by holding the iron handle 5. The anti-rust paint makes the iron handle 5 not easy to rust and prolongs the service life of the iron handle 5. The iron handle 5 does not take up space after hanging naturally. The magnet 51 can magnetically fix the naturally hanging iron handle 5, so that the iron handle 5 is not easy to swing with external factors such as wind.

[0031] The implementation principle of a wall-penetrating casing blocking structure of the utility model embodiment is:

[0032] During installation, people first pass the pipe 3 of the wire, cable and other lines through the embedded casing 2 to route, and at the same time put the plugging gland 4 on the outside of the pipe 3, and hold the iron handle 5 to drive the plugging gland 4 to rotate, and screw the plugging gland 4 into the embedded casing 2. At this time, the tapered hole 41 end of the plugging gland 4 will contact the first sealing ring 24, and with the continuous rotation of the plugging gland 4 and the inclined surface guidance of the tapered hole 41, the first sealing ring 24 is tightly pressed against the connection between the positioning ring 23, the pipe 3 and the plugging gland 4, so as to plug and seal the connection between the pipe 3, the embedded casing 2 and the plugging gland 4;

[0033] At the same time, when the sealing cover 4 rotates, it will press the second sealing ring 43, and the second sealing ring 43 will be tightly pressed in the sealing groove 42 to seal the connection between the wall 1, the embedded sleeve 2 and the sealing cover 4, thereby further sealing the two ends of the wall sleeve composed of the embedded sleeve 2, the water stop ring 21 and the wing disc 22, thereby improving the sealing and waterproof effect of the anti-blocking mechanism.
