Description

Technical Field

[0001] This utility model belongs to the field of pipe connection, specifically a water supply and drainage pipe connection device. Background Technology

[0002] In the field of water supply and drainage engineering, pipe connection is a key link to ensure smooth water delivery. Soft water pipes are a commonly used type of pipe in water supply and drainage. When connecting soft hoses, some existing technologies involve clamping the end of the hose to the joint to complete the connection. However, this method of connection by clamping alone has poor sealing effect, especially for some plastic joints, which are more prone to leakage. Therefore, we have designed a pipe connection device with better sealing effect. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] A water supply and drainage pipe connection device, such as Figure 1 , 2 As shown in Figures 3, 4, and 5, the system includes a water supply pipe connection end and a connecting pipe connection end. Both the water supply pipe connection end and the connecting pipe connection end include an externally threaded pipe 1. Two tapered pipes 2 are fixedly connected to both ends of the externally threaded pipe 1. The tapered pipes 2 communicate with and are coaxially arranged with the externally threaded pipe 1. Clamping pipes 3 are threadedly installed on the externally threaded pipe 1. One end of the clamping pipe 3 has an internal thread on its inner circumference. A water supply pipe 100 is clamped between the clamping pipe 3 and the tapered pipe 2 on one side, and a connecting pipe 110 is clamped between the clamping pipe 3 and the tapered pipe 2 on the other side. The tapered pipe 2 is fixed with... A support pipe 4 is installed, and an annular airbag 5 is fixedly mounted on the support pipe 4. The inner side of the annular airbag 5 is fixedly connected to the outer circumference of the support pipe 4. The annular airbag 5 is provided with several flat nozzles 6 that allow water to pass through in one direction. A through groove is opened on the support pipe 4 corresponding to the flat nozzles 6. One end of the flat nozzle 6 is fixedly connected to the through groove. One end of the flat nozzle 6 is funnel-shaped and fixedly connected to the inner wall of the through groove. The other end extends into the annular airbag 5 and is flat. Normally, it is in a closed state. The outer side of the annular airbag 5 is in contact with the water supply pipe 100 or the connecting pipe 110. This utility model has a simple structure and ingenious design. When water is supplied, water enters the annular airbag 5 through the flat nozzles 6, causing the annular airbag 5 to expand and fit tightly against the water supply pipe 100 or the connecting pipe 110, thereby increasing the sealing performance. When water squeezes the annular airbag 5 from the outside, the annular airbag 5 will expand radially and also fit tightly against the hose, increasing the sealing performance. It can meet practical needs and is suitable for promotion. In use, remove the clamping tubes 3 on both sides and sequentially install them onto the water supply pipe 100 and the connecting pipe 110. Then, insert the water supply pipe 100 and the connecting pipe 110 into the corresponding tapered pipe 2. At this point, the annular airbag 5 has extended into the water supply pipe 100 or the connecting pipe 110. Finally, screw the clamping tubes 3 onto the externally threaded pipe 1 to complete the connection. When water flows through the pipe, water enters the annular airbag 5 through the flat nozzle 6. The annular airbag 5 inflates and fits against the water supply pipe 100 or the connecting pipe 110. After water enters the annular airbag 5, the water pressure will press the end of the flat nozzle 6 that extends into the annular airbag 5 tightly, keeping it closed. The water cannot flow out in the opposite direction, thus keeping the annular airbag 5 in an inflated state and maintaining a seal. The water in the water supply pipe 100 and the connecting pipe 110 will also squeeze the annular airbag 5 from the outside, making it fit the water supply pipe 100 or the connecting pipe 110 even better. When it is necessary to drain the liquid in the annular airbag 5, the internal liquid can be drained by inserting a straw into the flat nozzle 6.

[0017] Specifically, as shown in the figure, several levers 20 are fixedly installed at one end of the clamping tube 3 in this embodiment, and the levers 20 are evenly distributed around the circumference. Twisting the clamping tube 3 by using the levers 20 makes it more convenient and less strenuous.

[0018] Specifically, as shown in the figure, the threaded pipe 1 in this embodiment is divided into two separate left and right sections. A short pipe 30 with external threads is fixedly installed on the threaded pipe 1, which communicates with the connecting pipe 110. The threaded pipe 1, which communicates with the water supply pipe 100, has internal threads and is threadedly connected to the short pipe 30. The tapered pipe 2 on the threaded pipe 1 has various models for connecting hoses of different sizes. The corresponding model of tapered pipe 2 is selected according to the size of the water supply hose, and the short pipe 30 and the corresponding threaded pipe 1 are connected. This is suitable for connecting hoses of various sizes, such as connecting a thicker water supply pipe 100 with a thinner connecting pipe 110, which improves practicality.

[0019] Furthermore, as shown in the figure, in this embodiment, the externally threaded pipe 1 connected to the water supply pipe 100 has an annular groove 40. A circular plate 41 is slidably installed in the annular groove 40. A stepped hole 42 is opened on the circular plate 41. A sealing plate 43 is sealed and fitted in the stepped hole 42. The sealing plate 43 is fixedly installed in the externally threaded pipe 1 by a connecting rod. One end of the connecting rod is fixedly connected to the sealing plate 42, and the other end of the connecting rod is fixedly connected to the inner wall of the externally threaded pipe 1. Several sliding holes 44 are opened on the circular plate 41. Guide rods 45 are slidably fitted in the sliding holes 44 respectively. The guide rods 45 are fixedly installed in the annular groove 40. The circular plate 41 is elastically connected to the inner wall of the annular groove 40 by several springs 46. Springs 46 are respectively fitted on the guide rods 45. One end of the spring 46 is fixedly connected to the circular plate 41, and the other end of the spring 46 is fixedly connected to the inner wall of the annular groove 40. When the short pipe 30 is screwed into the external threaded pipe 1 and comes into contact with the circular plate 41, the short pipe 30 pushes the circular plate 41 to slide, the spring 46 is compressed, and the circular plate 41 separates from the sealing plate 43. After separation, water can flow from the stepped hole 42. When the short pipe 30 falls off, the circular plate 41 can be reset under the action of the spring 46, so that the sealing plate 42 re-seals the stepped hole 42, reducing liquid leakage and water waste.

[0020] Furthermore, as shown in the figure, a sealing gasket 50 is fixedly installed on the circular plate 41 in this embodiment. The sealing gasket 50 fits against the side wall of the annular groove 40, and the sealing gasket 50 has a through hole through which the guide rod 45 passes. The sealing gasket 50 can increase the sealing effect between the circular plate 41 and the annular groove 40.

[0021] Furthermore, as shown in the figure, annular grooves 60 are respectively formed on the tapered pipe 2 in this embodiment, and sealing rings 61 are installed in the annular grooves 60. The sealing rings 61 fit against the inner wall of the water supply pipe 100 or the inner wall of the connecting pipe 110. The sealing rings 61 can further increase the sealing between the water supply pipe 100 or the connecting pipe 110 and the tapered pipe 2, and further reduce the possibility of water leakage.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
