It includes water supply pipes, drainage pipes, rainwater pipes and other parts, and is an important part of urban infrastructure. The design and construction of water supply and drainage pipe systems are crucial to ensuring the domestic water supply of urban residents, the normal operation of industrial production and the cleanliness of the urban environment.

[0003] Existing water supply and drainage pipes are usually connected by hot-melt connection. If the water supply and drainage pipes are affected by external factors such as vibration, the hot-melt connection may be partially cracked, which may lead to water seepage in the water supply and drainage pipes. In addition, there may be inherent defects in the hot-melt installation of the water supply and drainage pipes. Even if the pipes are in the installed state, some hot-melt connection positions may be missing, and water seepage may also occur later. For this reason, we provide an anti-seepage device for water supply and drainage pipes. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-seepage device for water supply and drainage pipes, comprising: an anti-seepage mechanism, the anti-seepage mechanism comprising a connecting pipe, both ends of the connecting pipe are sleeved with water pipes, the water pipes are slidably connected to the connecting pipe, an inclined groove is provided on the water pipe, both ends of the connecting pipe are provided with semicircular blocks, the semicircular blocks are slidably connected to the connecting pipe, one end of the semicircular block is fixedly connected to a telescopic column, the outer surface of the telescopic column is sleeved with an extrusion sheet, the extrusion sheet is fixedly connected to the telescopic column, the outer surface of the telescopic column is sleeved with a spring, and the end of the telescopic column away from the semicircular block is fixedly connected to an arc-shaped sheet.

[0006] As a preferred implementation, two ends of the spring are fixedly connected to the outer surface of the extrusion sheet and the inner wall of the connecting pipe respectively.

[0007] As a preferred implementation, a rubber ring is provided on one side of the arc-shaped piece, and the rubber ring is sleeved in a mounting groove provided inside the connecting pipe.

[0008] As a preferred embodiment, an O-ring is provided inside the connecting pipe, and the O-ring is placed in a sealing groove opened inside the connecting pipe.

[0009] As a preferred implementation, a threaded ring is sleeved on the outer surface of the connecting pipe, and the threaded ring is threadedly connected to the connecting pipe.

[0011] As a preferred implementation, the limiting ring is fixedly connected to the connecting pipe.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] The utility model provides an anti-seepage mechanism, so that the water supply and drainage pipe will not seep water due to poor sealing effect after connection. Compared with the traditional water supply and drainage pipe hot-melt connection method, the anti-seepage mechanism has a more stable seal for the connecting pipe and the water pipe, and there is no need to worry about the cracking of the hot-melt part of the connecting pipe and the water pipe caused by external vibration when the hot-melt connection method is adopted. Therefore, the anti-seepage device for connecting the water supply and drainage pipe is more practical. The arc block and the rubber ring are provided.

[0023] The following will be combined with the drawings in 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 in 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.

[0024] Example 1

[0025] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: an anti-seepage device for water supply and drainage pipes, comprising: an anti-seepage mechanism 1, the anti-seepage mechanism 1 comprises a connecting pipe 11, both ends of the connecting pipe 11 are sleeved with a water pipe 12, the water pipe 12 is slidably connected to the connecting pipe 11, an inclined groove 13 is provided on the water pipe 12, both ends of the connecting pipe 11 are provided with a semicircular block 14, the semicircular block 14 is slidably connected to the connecting pipe 11, one end of the semicircular block 14 is fixedly connected to a telescopic column 15, the outer surface of the telescopic column 15 is sleeved with an extrusion sheet 16, the extrusion sheet 16 is fixedly connected to the telescopic column 15, the outer surface of the telescopic column 15 is sleeved with a spring 17, the end of the telescopic column 15 away from the semicircular block 14 is fixedly connected to an arcuate sheet 18, the two ends of the spring 17 are respectively fixedly connected to the outer surface of the extrusion sheet 16 and the inner wall of the connecting pipe 11, and a rubber ring 19 is provided on one side of the arcuate sheet 18.

[0026] In this embodiment, by providing a semicircular block 14, and the surface of the semicircular block 14 is smooth, the semicircular block 14 can be squeezed into the interior of the connecting pipe 11 by the threaded ring 102. When the semicircular block 14 enters the interior of the connecting pipe 11, it will drive the telescopic column 15 to synchronously drive the arc piece 18. At this time, the originally relatively scattered arc pieces 18 will form a complete spliced ​​ring, so as to squeeze the rubber ring 19 so that it fits tightly with the water pipe 12, and then there will be no water seepage between the rubber ring 19 and the water pipe 12. In addition, when the telescopic column 15 moves, the squeezing sheet 16 will be used to compress the spring 17, and the spring 17 will generate elastic force. Then, when the squeezing of the semicircular block 14 by the threaded ring 102 disappears, the elastic force of the spring 17 will automatically reset the telescopic column 15 and the semicircular block 14.

[0027] Example 2

[0028] like Figure 1-Figure 6 As shown, the rubber ring 19 is sleeved in the installation groove opened inside the connecting tube 11, an O-ring 101 is provided inside the connecting tube 11, and the O-ring 101 is placed in the sealing groove opened inside the connecting tube 11. A threaded ring 102 is sleeved on the outer surface of the connecting tube 11, and the threaded ring 102 is threadedly connected to the connecting tube 11. A threaded groove 103 matching the threaded ring 102 is opened on the connecting tube 11, and a limit ring 104 is sleeved on the outer surface of the connecting tube 11, and the limit ring 104 is fixedly connected to the connecting tube 11.

[0029] In this embodiment, an O-ring 101 is provided, and the O-ring 101 is placed in a sealing groove opened inside the connecting pipe 11, and a bevel groove 13 is opened on the water pipe 12. When the water pipe 12 enters the connecting pipe 11, the water pipe 12 will use the bevel groove 13 to squeeze and deform the O-ring 101, so that the O-ring 101 can fit tightly on the outer surface of the water pipe 12, thereby playing a role in anti-seepage. In addition, a limit ring 104 is provided to limit the rotation range of the threaded ring 102.

[0030] Working principle:

[0031] like Figure 1-Figure 6 As shown, when the utility model is used, the O-ring 101 can be placed in the sealing groove provided inside the connecting pipe 11 first, and then the rubber ring 19 can be placed in the installation groove provided inside the connecting pipe 11, and the water pipe 12 can be inserted into the connecting pipe 11, and the water pipe 12 can use the inclined groove 13 to squeeze the O-ring 101 into the sealing groove while being inserted, so that the O-ring 101 can be sleeved on the outer surface of the water pipe 12 and be in a tightly fitting state. After that, when the water pipes 12 at both ends of the connecting pipe 11 are inserted to the same distance and contact each other, the threaded ring 102 can be rotated, and the threaded ring 102 can be rotated and moved with the cooperation of the threaded groove 103 provided on the connecting pipe 11, and the threaded ring 10 2 will squeeze the semicircular block 14 while rotating and moving, so that the semicircular block 14 enters the interior of the connecting pipe 11. At the same time, the semicircular block 14 will use the telescopic column 15 to drive the arc piece 18, so that the dispersed arc pieces 18 form a spliced ​​ring, and then squeeze and deform the rubber ring 19, so that the rubber ring 19 is tightly fitted with the outer surface of the water pipe 12, so as to achieve the effect of anti-seepage. When the telescopic column 15 is squeezed and slid, the squeezing sheet 16 will compress the spring 17, so that the spring 17 generates elastic force. When the threaded ring 102 rotates in the opposite direction, the elastic force of the spring 17 will be released and reset the telescopic column 15, the semicircular block 14 and other components, so that the water pipe 12 and the connecting pipe 11 can be separated.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
