[0002] In the production and application of garden hoses, pressure resistance is a key indicator of their safety and reliability. Traditional manual testing methods are time-consuming and inefficient, and cannot guarantee accuracy and consistency. Therefore, the development of an automated and efficient device for testing the pressure resistance of garden hoses is particularly important.

[0003] There are already a variety of pipe pressure testing equipment on the market. They can simulate the pressure conditions of pipes in actual use. By gradually increasing the internal water pressure until the pipe breaks, the pressure resistance and ultimate bearing capacity of the pipe are evaluated.

[0004] However, traditional testing equipment cannot change the testing position, so it is impossible to test different parts of the water pipe, resulting in low testing efficiency. Therefore, a garden water pipe pressure resistance performance testing device that can change the testing position is needed. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention provides a device for testing the pressure resistance of a flat ribbon explosion-proof garden hose. Figure 1-3 As shown, it includes an inner body 11, an outer body 12, a first sleeve 13, a second sleeve 14, a sliding plate 15, a first slot 16, a slide rail 17, an electric telescopic rod 18, a first curved surface 20, a second curved surface 21, a first opening 22, a pressure sensor 23, a second slot 24, a magnetic block 25, an electromagnet 26, a third slot 27, a fourth slot 28, a first roller 29, a roller base 30, and a second roller 31.

[0022] like Figure 1-3 As shown, a first sleeve 13 is fixedly provided on the outer circular surface of the inner body 11, and a second sleeve 14 is fixedly provided on the outer circular surface of the outer body 12. A first curved surface 20 is provided on an end surface of the inner body 11 close to the outer body 12, and a second curved surface 21 is provided on an end surface of the outer body 12 close to the inner body 11. A sliding assembly is provided on the first sleeve 13, and a sliding plate 15 is slidably connected to the inner body 11. An end of the sliding plate 15 close to the first curved surface 20 is fixedly connected to an electric telescopic rod 18. A first opening 22 is provided on both the first curved surface 20 and the second curved surface 21, and a pressure sensor 23 is provided in the first opening 22 of the second curved surface 21.

[0023] A first slot 16 is provided on the sliding plate 15, and a slide rail 17 is fixedly provided on the inner circular surface of the inner main body 11. The first slot 16 is slidably connected to the slide rail 17. The curvature of the first curved surface 20 is equal to the curvature of the second curved surface 21. A second slot 24 is provided in the first curved surface 20, and a magnetic block 25 is fixedly provided in the second slot 24. An electromagnet 26 is fixedly connected to the outer main body 12, and the electromagnet 26 is used to generate magnetic force on the magnetic block 25.

[0024] It is worth noting that the electric telescopic rod 18 and the electromagnet 26 are both existing technologies, and the pressure sensor 23 is externally connected to a display screen, which can display the pressure detected by the pressure sensor 23.

[0025] The sliding assembly includes a roller base 30 and a second roller 31. The roller base 30 is fixedly connected to the first sleeve 13. The second roller 31 is rotatably connected to the roller base 30. A third slot 27 is provided on an end surface of the second sleeve 14 close to the first sleeve 13. The third slot 27 is adapted to the second roller 31. A fourth slot 28 is also provided in the third slot 27. The first roller 29 is rotatably connected in the fourth slot 28.

[0026] When the present scheme is used to test the pressure resistance of the flat webbing explosion-proof garden water pipe, first, the inspector places the inner body 11 inside the water pipe and the outer body 12 outside the water pipe, aligning the second curved surface 21 with the first curved surface 20, and starting the electromagnet 26. The electromagnet 26 generates magnetism and generates magnetic force on the magnetic block 25, so that the first curved surface 20 and the second curved surface 21 are tightly fitted to the inner and outer walls of the water pipe.

[0027] Then, the electric telescopic rod 18 is started, which pulls the sliding plate 15 toward the first curved surface 20. The water pressure between the sliding plate 15 and the first curved surface 20 increases, and the water pressure is transmitted to the water pipe through the first opening 22 of the first curved surface 20 until the water pipe ruptures or leaks outward due to excessive water pressure. After passing through the water pipe wall, the water enters the first opening 22 of the second curved surface 21, and the pressure sensor 23 sends an electrical signal to the display screen.

[0028] Finally, the inspector can hold the outer body 12 and move the position of the outer body 12 on the outer wall of the water pipe to change the position of the inner body 11 on the inner wall of the water pipe, and inspect different inner wall positions.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
