[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] See also Figure 1-Figure 3The anti-leakage sealer for the pipe joint of this embodiment can connect the pipe, and at the same time can realize the secondary sealing of the connection position, and at the same time can protect the connection position, and avoid the leakage and leakage caused by the corrosion of the pipe connection to the greatest extent. It can also limit the liquid at a specific position when liquid leakage occurs, so as to prevent the leaked liquid from contacting the outside of the pipe at more positions, corroding the pipe, and affecting the service life of the pipe. In this embodiment, it mainly includes two coaxial and mutually detachable connecting pipes 1. The opposite ends of the connecting pipe 1 are integrally provided with a connecting portion 5, and a first rubber ring 6 is provided between the two connecting portions 5. The ends of the connecting pipe 1 at the opposite ends of the connection position are integrally provided with a threaded portion 7. A second rubber ring 8 is fixedly provided on the connecting pipe 1 inside the threaded portion 7, and the second rubber ring 8 is designed in a triangular structure.

[0025] The connecting pipe 1 is connected to the water supply and drainage pipe through threads. At this time, the water supply and drainage pipe fits with the second rubber ring 8 to achieve the seal between the water supply and drainage pipe and the connecting pipe 1. Then the connecting parts 5 of the two connecting pipes 1 are abutted and aligned, and the two connecting pipes 1 are fixed by the bolt structure to achieve the connection of the pipeline. In this process, the first sealing ring is placed in the middle of the two connecting parts 5 to achieve the first sealing of the pipeline.

[0026] In order to achieve secondary sealing and protection of the pipeline. Figure 1-Figure 3 In this embodiment, a sealing tube 2 is disposed outside the connecting tube 1 to surround the detachable position of the connecting tube 1. The sealing tube 2 includes an upper half tube 21 and a lower half tube 22. The upper half tube 21 and the lower half tube 22 are both detachably disposed through fixing portions 25 disposed at both ends thereof. The middle portions of the upper half tube 21 and the lower half tube 22 are both semicircular thin-walled structures. A plurality of support rods 23 are fixedly disposed at the bottom end of the middle portion of the lower half tube 22. An elastic tube 3 is disposed between the sealing tube 2 and the connecting tube 1 to completely surround the detachable position of the connecting tube 1. The elastic tube 3 is made of a rubber material with high thickness and elasticity. A third rubber ring 24 is disposed at the contact position between the elastic tube 3 and the connecting tube 1. The fixing portions 25 of the upper half tube 21 and the lower half tube 22 are located at the ends of the elastic tube 3 corresponding to the third rubber ring 24. The elastic tube 3 can also be sleeved on the water supply and drainage pipe outside the threaded portion 7 of the connecting pipe 1 according to actual conditions, and the two ends of the elastic tube 3 are fixed to the water supply and drainage pipe through the fixing parts 25 of the upper half pipe 21 and the lower half pipe 22.

[0027] Before the connecting pipe 1 is installed by the bolt structure, the elastic tube 3 is sleeved on one of the connecting pipes 1. After the connecting pipe 1 is installed, the elastic tube 3 is pulled onto the other connecting pipe 1 so that it completely wraps the connecting portion 5 of the two connecting pipes 1. At the same time, the third sealing ring is placed inside the two ends of the elastic tube 3 to fit the connecting pipe 1. At this time, the upper half pipe 21 and the lower half pipe 22 are covered at the two ends of the elastic tube 3 and fixed by the bolt structure, and the elastic tube 3 and the third sealing ring are squeezed on the connecting pipe 1. At the same time, the elastic tube 3 and the third sealing ring can be placed on the water supply and drainage pipeline at the end of the connecting pipe 1 according to actual conditions. At this time, the upper half pipe 21 and the lower half pipe 22 are covered at the two ends of the elastic tube 3 and fixed by the bolt structure, and the elastic tube 3 and the third sealing ring are squeezed on the water supply and drainage pipeline. Thereby realizing the secondary sealing of the pipeline. At this time, the connection position can be protected by the sealing tube 2 and the elastic tube 3, and the leakage and leakage caused by corrosion of the pipeline connection can be avoided to the greatest extent.

[0028] When leakage occurs at the connection position of the connecting pipe 1, the leaked liquid will be wrapped by the elastic tube 3, thereby preventing the liquid from appearing at other positions of the pipeline, corroding the pipeline, and affecting the service life of the pipeline. When the liquid continues to leak, the elastic tube 3 will expand until it fits with the inner walls of the upper half pipe 21 and the lower half pipe 22. At this time, the leaked liquid is blocked by the elastic tube 3, and the expanded elastic tube 3 can be blocked by the sealing tube 2, thereby achieving secondary sealing after the pipeline leaks.

[0029] In order to detect the extent of liquid leakage. In this embodiment, see Figure 3 , a reminder mechanism 4 for detecting the degree of pipeline leakage is provided at the top of the sealing tube 2. The reminder mechanism 4 includes a cylinder 41 fixedly provided at the middle of the top of the upper half tube 21, a detection rod 42 is slidably provided inside the cylinder 41, and a scale group 43 is integrally provided on the detection rod 42. A C-shaped rod 44 with an end located above the detection rod 42 is fixedly provided on the side of the cylinder 41, and a touch switch 45 that can abut against the detection rod 42 is fixedly provided on the C-shaped rod 44 above the detection rod 42.

[0030] When leakage occurs at the connection position of the connecting tube 1 and the elastic tube 3 expands to a certain position, the elastic tube 3 will lift the detection rod 42 to make it slide inside the cylinder 41. At this time, the volume of the internal liquid can be checked through the scale group 43, so as to detect the leakage. When the liquid leakage is serious, the elastic tube 3 completely lifts the detection rod 42, and the top of the detection rod 42 abuts against the touch switch 45, so that the touch switch 45 sends a signal to the outside to remind.

[0031] The method of using the anti-leakage sealer for pipe joints of the utility model is as follows: first, the connecting pipe 1 is connected to the water supply and drainage pipe through a thread, and the sealing between the water supply and drainage pipe and the connecting pipe 1 is achieved by the second rubber ring 8 and the threaded portion 7. Then the elastic tube 3 is sleeved on one of the connecting pipes 1. The connecting parts 5 of the two connecting pipes 1 are abutted and aligned, and the first sealing ring is placed in the middle position, and the two connecting pipes 1 are fixed by a bolt structure, so as to achieve the connection of the pipeline. The first sealing of the pipeline is achieved. The elastic tube 3 is pulled onto the other connecting pipe 1 so that it completely wraps the connecting parts 5 of the two connecting pipes 1. At the same time, the third sealing ring is placed on the inner side of the two ends of the elastic tube 3 to fit with the connecting pipe 1. At this time, the upper half pipe 21 and the lower half pipe 22 are covered on the two ends of the elastic tube 3 and fixed by a bolt structure, and the elastic tube 3 and the third sealing ring are squeezed on the connecting pipe 1. At the same time, the elastic tube 3 and the third sealing ring can be placed on the water supply and drainage pipe at the end of the connecting pipe 1 according to the actual situation. At this time, the upper half pipe 21 and the lower half pipe 22 are covered at both ends of the elastic tube 3 and fixed by a bolt structure, and the elastic tube 3 and the third sealing ring are squeezed on the water supply and drainage pipe. Thus, the secondary sealing of the pipeline is achieved. At this time, the connection position can be protected by the sealing tube 2 and the elastic tube 3, and the leakage caused by corrosion at the pipeline connection can be avoided to the greatest extent.

[0032] When leakage occurs, the leaked liquid will be wrapped by the elastic tube 3, so as to avoid the liquid from appearing in other positions of the pipeline, corroding the pipeline and affecting the service life of the pipeline. When the liquid continues to leak, the elastic tube 3 will expand until it fits with the inner wall of the upper half pipe 21 and the lower half pipe 22. At this time, the liquid after the leakage is blocked by the elastic tube 3, and the expanded elastic tube 3 can be blocked by the sealing tube 2 at the same time, so as to realize the secondary sealing after the pipeline leakage. In this process, the elastic tube 3 will lift the detection rod 42 so that it slides inside the cylinder 41. At this time, the volume of the internal liquid can be checked by the scale group 43, so as to realize the detection of the leakage. When the liquid leakage is more serious, when the elastic tube 3 fully raises the detection rod 42, the top of the detection rod 42 will abut against the touch switch 45, so that the touch switch 45 sends a signal to remind the outside.
