[0002] A metal pipe joint is a component for connecting metal pipes, usually composed of two ports and an intermediate part connecting these two ports, and is widely used in fields such as aviation, automotive, chemical industry, medical treatment, construction, and industry.

[0003] The patent with the patent authorization publication number CN215950643U discloses a metal pipe joint. This patent seals the metal pipe joint through soft - seal reinforcement. However, there are still some deficiencies in its actual use. Since the above - mentioned patent has no leak - reporting mechanism, the water pipe will age and leak after long - term use. And when the leakage time of the water pipe is long and not discovered in time, the aged water pipe will expand the leakage port due to water pressure, resulting in more water leakage.

[0004] Therefore, it is necessary to provide a leak - proof metal pipe joint that can automatically report leaks. Summary of the Utility Model

[0008] Further explanation: It also includes an expansion tube, a one-way water inlet pipe, a water outlet valve, a sliding block, a telescopic rod, a return spring, a sleeve, a gasket, a support ring and a waterproof cloth. Two support rings are embedded in the connecting cylinder. A waterproof cloth is arranged inside the support ring. A gasket is arranged between the two waterproof cloths. Four groups of sleeves are fixedly connected inside the connecting cylinder, with two sleeves in one group. Four sliding blocks are evenly spaced outside the gasket. Telescopic rods are symmetrically fixedly connected up and down outside the sliding block. A return spring is connected between the telescopic rod and the connecting cylinder. The telescopic rod slides inside the sleeve. An expansion tube is placed inside the four sliding blocks. A one-way water inlet pipe is connected to the expansion tube. A water outlet valve is arranged on the expansion tube.

[0009] Further explanation: It also includes an anti-slip sleeve. An anti-slip sleeve for increasing friction is sleeved on one end of the threaded rod.

[0010] Further explanation: It also includes a rubber gasket. A sealed rubber gasket is stuffed between the two connecting rings.

Detailed implementation manners

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1: An anti-leakage metal pipe joint, refer to Figures 1 - 3 As shown, it includes a connecting pipe 1, a threaded joint 2 and a filter plate 3. The bottom end of the connecting pipe 1 is connected with the threaded joint 2, and the filter plate 3 is embedded in the lower part of the connecting pipe 1. It also includes a connecting cylinder 11, a water leakage detector 12, a controller 13 and an alarm 14. The lower part of the threaded joint 2 is threadedly connected with the connecting cylinder 11. The water leakage detector 12 is arranged in the middle of the connecting cylinder 11 by means of bolt connection, and the controller 13 is arranged on the outer side of the connecting cylinder 11 by means of bolt connection. The controller 13 is electrically connected with the water leakage detector 12, and two alarms 14 are installed on the controller 13. The alarms 14 are electrically connected with the controller 13.

[0023] Refer to Figure 2 As shown, it also includes a filter net 10, and the filter net 10 for filtering is embedded in the upper part of the connecting pipe 1.

[0024] When the installation of the metal joint is completed and the water pipe leaks during use, the amount of water transmitted by the water pipe becomes smaller. The water leakage detector 12 detects the water leakage, and then the water leakage detector 12 sends a signal to the controller 13, so that the controller 13 controls the alarm 14 to give an alarm, thereby achieving the effect of automatic leak reporting, enabling the staff to discover and repair in time. The filter plate 3 and the filter net 10 can filter water.

[0025] Embodiment 2: On the basis of Embodiment 1, refer to Figure 1 and Figure 2As shown, it further includes a limit ring 4, a snap ring 5, a sliding rod 6, a threaded rod 7 and a connecting ring 8. A limit ring 4 is fixedly connected to the connecting pipe 1. Two sliding rods 6 are symmetrically arranged in the front and back on the limit ring 4 in a sliding manner. A snap ring 5 is fixedly connected between the two corresponding sliding rods 6. A connecting ring 8 is fixedly connected to the inner side of the snap ring 5. Threaded rods 7 are arranged in a threaded manner on the front and back parts of the two snap rings 5.

[0026] Refer to Figure 2 As shown, it further includes an anti-slip sleeve 25. An anti-slip sleeve 25 for increasing friction is sleeved on one end of the threaded rod.

[0027] Refer to Figure 1 and Figure 2 As shown, it further includes a rubber pad 9. A rubber pad 9 for enhancing sealing is stuffed between the two connecting rings 8.

[0028] When it is necessary to install a metal joint, first place the water pipe between the two connecting rings 8. By rotating the threaded rod 7, the two snap rings 5 move inward to drive the connecting ring 8 to move inward, thereby clamping the water pipe, achieving the effect of rapid installation, reducing the workload of the staff, and the rubber pad 9 can enhance the sealing.

[0029] Refer to Figures 3 - 5 As shown, it further includes an expansion tube 15, a one-way water inlet pipe 16, a water outlet valve 17, a sliding block 18, a telescopic rod 19, a return spring 20, a sleeve 21, a sealing gasket 22, a support ring 23 and a waterproof cloth 24. Two support rings 23 are embedded in the connecting cylinder 11. A waterproof cloth 24 is arranged on the inner side of the support ring 23. A sealing gasket 22 is arranged between the two waterproof cloths 24. Four groups of sleeves 21 are fixedly connected to the connecting cylinder 11 at equal intervals. One group has two sleeves 21. Four sliding blocks 18 are arranged at equal intervals on the outer side of the sealing gasket 22. Telescopic rods 19 are symmetrically arranged on the upper and lower sides of the outer side of the sliding block 18 by welding. A return spring 20 is connected between the telescopic rod 19 and the connecting cylinder 11. The telescopic rod 19 slides in the sleeve 21. An expansion tube 15 is placed in the four sliding blocks 18. A one-way water inlet pipe 16 is connected to the expansion tube 15. A water outlet valve 17 is arranged on the expansion tube 15.

[0030] When the water pipe leaks, by inputting water into the one-way water inlet pipe 16 to the expansion tube 15, the water expands the expansion tube 15, so that the expansion tube 15 squeezes the sealing gasket 22 and the waterproof cloth 24. The sealing gasket 22 shrinks to drive the sliding block 18 and the telescopic rod 19 to move, and the return spring 20 deforms, thereby achieving the effect of rapid water stoppage, facilitating the staff to better repair the water pipe. After the water pipe repair is completed, open the water outlet valve 17 to drain the water in the expansion tube 15 to restore it to its original state.

[0031] It should be understood that the above description is for exemplary purposes only and is not intended to limit the present utility model. Those skilled in the art will understand that variations of the present utility model will be included within the scope of the claims herein.
