Description

Technical Field

[0001] The utility model relates to the technical field of connection structures of sewage pipes, and specifically to a leakage-proof connection structure for municipal sewage pipes. Background Art

[0002] Municipal sewage pipes are pipe systems used to collect and transport sewage. Their design and maintenance are of great significance to the urban environment and people's health. In the process of laying sewage pipes, they often have to pass through the walls of buildings, and the walls will produce squeezing force on the sewage pipes, causing the sewage pipes to rupture and the sewage in the sewage pipes to flow out.

[0003] The existing anti-leakage connection structure for municipal sewage pipes passing through walls is: a stop-type sleeve is set between the wall and the sewage pipe, and an elastic rubber ring is added between the wall, the sleeve and the sewage pipe. The elastic force generated by the deformation of the elastic rubber ring ensures that the wall, the sleeve and the sewage pipe fit closely and will not fall off. The stop-type sleeve bears the pressure of the wall on the sewage pipe, reducing the risk of side leakage of the sewage pipe.

[0004] Although this can reduce the side leakage of the sewage pipe when it passes through the wall, it still has the following disadvantages: the sewage pipe may age during long-term use. The elastic force generated by the deformation of the rubber ring may make it difficult to remove the sewage pipe from the wall, making it difficult to disassemble, replace and repair the sewage pipe.

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 2 to Figure 5 As shown, this embodiment proposes a connection structure for preventing leakage of municipal sewage pipes, which is used to install sewage pipes on walls, including a pipe body 3. Among them, the installation hole 31 in this embodiment is set in the pipe body 3 for installing the sewage pipe, the limit plate 1 is fixedly set at the end of the pipe body 3, and the limit bolt 11 is fixedly set on the limit plate 1 for fixing the pipe body 3. The first connection layer 21 is fixedly set in the installation hole 31, and the second connection layer 22 is fixedly set on the outer wall of the pipe body 3. The first connection layer 21 and the second connection layer 22 are both made of elastic material. The first sliding groove 32 is set on the pipe body 3, and the central axis of the first sliding groove 32 is parallel to the central axis of the pipe body 3. The sliding member 4 is slidingly set in the first sliding groove 32. A plurality of first locking mechanisms are set between the sliding member 4 and the first connection layer 21 to make the first connection layer 21 close to the sewage pipe or away from the sewage pipe. A plurality of second locking mechanisms are set between the sliding member 4 and the second connection layer 22 to make the second connection layer 22 close to the wall or away from the wall.

[0028] In this embodiment, the first connection layer 21 is fixedly connected to one end of the mounting hole 31 close to the limiting plate 1 and to one end of the mounting hole 31 away from the limiting plate 1, a gap is provided between the first connection layer 21 and the mounting hole 31, and the connection structure between the second connection layer 22 and the outer wall of the pipe body 3 is the same as the connection structure between the first connection layer 21 and the mounting hole 31. Such a design enables the first connection layer 21 and the second connection layer 22 to adjust and control the contact pressure between the sewage pipe and the wall, so as to facilitate faster removal of the sewage pipe relative to the pipe body 3.

[0029] The first locking mechanism in this embodiment includes a sliding member 4, a plurality of sliding holes 33 are arranged on the inner wall of the first sliding groove 32, each sliding hole 33 points to the central axis of the tube body 3, and the sliding member 4 is slidingly connected with the sliding hole 33. An adjustment structure is arranged on the sliding member 4 to control the sliding member 4 to abut against the first connecting layer 21. A limiting structure is arranged in the sliding hole 33 to control the sliding member 4 to maintain abutment against the adjustment structure. The first locking mechanism and the second locking mechanism have the same structure, which will not be described in detail in this embodiment. In this embodiment, by controlling the movement of the sliding member 4 relative to the first connecting layer 21, the first connecting layer 21 is driven to contact with the sewage pipe, and the contact area with the sewage pipe is increased by the elastic deformation of the first connecting layer 21, so that a larger friction force is generated between the first connecting layer 21 and the sewage pipe, ensuring that the first connecting layer 21 and the sewage pipe remain in a fixed position, and the sewage pipe will not be relatively separated from the tube body 3.

[0030] The limiting structure in this embodiment includes a second sliding groove 34, which is arranged between the sliding hole 33 and the first sliding groove 32. The cross section of the second sliding groove 34 is a rectangular structure, which is used to ensure that the sliding member 4 does not rotate when sliding, and better contact with the first connecting layer 21. The projection surface of the sliding hole 33 is arranged within the projection surface of the second sliding groove 34, and the limiting spring 44 is arranged in the second sliding groove 34. The two ends of the limiting spring 44 are respectively fixedly connected to the sliding member 4 and the bottom of the second sliding groove 34. The design of the limiting spring 44 is to ensure that the sliding member 4 always maintains contact with the sliding member 4, which is convenient for the movement of the sliding member 4 when controlling the movement of the sliding member 4.

[0031] The adjustment structure in this embodiment includes an adjustment block 5, which is fixedly arranged on the sliding member 4. The adjustment block 5 includes a first abutting portion 51 and a disengaging portion 52. The first abutting portion 51 is a cylindrical structure, and the disengaging portion 52 is a truncated cone structure. The first abutting portion 51 and the disengaging portion 52 are fixedly connected, and the cross-sectional area of ​​the disengaging portion 52 close to the first abutting portion 51 is larger than the cross-sectional area of ​​the disengaging portion 52 away from the first abutting portion 51. Such a design is to make the sliding member 4 abut against the first abutting portion 51. Since the distance between the sliding hole 33 and the first abutting portion 51 is relatively close, the locking block can be pushed and slide out relative to the first sliding groove 32, so as to push the first connecting layer 21 to contact with the outer wall of the sewage pipe. When the sliding member 4 contacts the disengaging portion 52, since the distance between the sliding hole 33 and the disengaging portion 52 is relatively far, the sliding member 4 is pushed to move away from the first connecting layer 21, so that the first connecting layer 21 and the sewage pipe are freed from the restraint, and the sewage pipe can be easily disassembled.

[0032] The sliding member 4 in this embodiment includes a sliding rod 42, which is slidingly connected to the sliding hole 33. The two ends of the sliding rod 42 are respectively provided with a first connecting block 41 abutting against the first connecting layer 21, and a second connecting block 43 abutting against the adjusting block 5. The second connecting block 43 includes a sliding portion 431 and a second abutting portion 432. Among them, the sliding portion 431 is slidingly connected to the second sliding groove 34, and the second abutting portion 432 abuts against the adjusting block 5. The sliding portion 431 is a rectangular parallelepiped structure, and the cross-section of the second abutting portion 432 is a right-angled triangle structure. The design of the second abutting portion 432 is to better cooperate with the first abutting portion 51, so that the second abutting portion 432 can slide relative to the first abutting portion 51.

[0033] The screw rod 53 in this embodiment is arranged at the end of the sliding member 4, the limit plate 1 is provided with a threaded hole 13 threadedly connected to the screw rod 53, and the adjusting bolt 12 is fixedly arranged at the end of the screw rod 53. Such a design enables the tightness of the fit between the sewage pipe, the pipe body 3 and the wall to be controlled and adjusted according to the actual needs of the site, avoiding the loose installation caused by too loose, and avoiding the squeezing damage of the sewage pipe caused by too tight.

[0034] The working process of this embodiment is as follows: when the sewage pipe needs to be installed on the wall, the sewage pipe is first placed in the installation hole 31, and then the pipe body 3 is placed in the wall, and then the adjusting bolt 12 is rotated so that the first abutting portion 51 replaces the disengaging portion 52 to abut against the sliding member 4, so that the first connecting block 41 squeezes the first connecting block 41, and the first connecting block 41 pushes the first connecting layer 21 to abut against the outer wall of the sewage pipe to ensure that the sewage pipe is installed and fixed. At this time, the second connecting layer 22 is also pushed by the second locking structure to abut against the box body, ensuring that the pipe body 3 abuts against the sewage pipe and the wall at the same time, and finally the pipe body 3 is connected and fixed to the wall by rotating the limit bolt 11; when the sewage pipe is damaged and needs to be replaced, the regulating valve is rotated so that the disengaging portion 52 replaces the first abutting portion 51 to abut against the sliding member 4, and under the action of the limit spring 44, the sliding member 4 begins to move away from the first connecting layer 21, and the first connecting layer 21 is separated from the sewage pipe. At this time, the sewage pipe can be removed and replaced.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
