Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4 This utility model provides a technical solution for automotive intake and exhaust flanges: including a first flange 1, a second flange 16, a retaining plate 5, and a retaining groove 14. A retaining plate 5 is provided at the ends of the first flange 1 and the second flange 16 that are far apart from each other. The retaining plate 5 is movably connected to the first flange 1 and the second flange 16 via a rotating shaft. The retaining plates 5 on the first flange 1 and the second flange 16 are staggered. A retaining groove 14 is provided between two adjacent retaining plates 5 on the first flange 1 and the second flange 16. The retaining plates 5 and retaining grooves 14 are staggered. The retaining plate 5 has a U-shaped structure. A threaded sleeve 8 is slidably provided on the inner side of the end of the retaining plate 5 away from the rotating shaft. The threaded sleeve 8 has a square structure and fits into the retaining groove 14. A threaded groove 9 is provided in the middle of one side of the threaded sleeve 8. A screw 7 is movably provided on the outer side of the end of the retaining plate 5 with the threaded sleeve 8 via a bearing. The screw 7 extends into the interior of the threaded groove 9 and is spirally connected to its inner wall. A knob 6 is fixedly installed on the other end of the screw 7.
[0022] Specifically, sleeve 2 and insert 18 are respectively provided on the opposite sides of the first flange 1 and the second flange 16. The insert 18 is inserted into the inside of the sleeve 2 and in close contact with its inner wall.
[0023] Specifically, the second flange 16 has an outer groove 17 on the side near the first flange 1, and the sleeve 2 is inserted into the outer groove 17 and in close contact with it.
[0024] Specifically, the inner side of the card plate 5 has a threaded sleeve 8 with a guide post 10 fixedly installed around one end. The threaded sleeve 8 has a guide groove 11 around its perimeter, and the guide post 10 extends into the guide groove 11 and slides in connection with its inner wall.
[0025] Specifically, limit blocks 12 are fixedly installed on both sides of the end of the guide post 10, and limit grooves 13 are fixedly opened on both sides of the inner wall of the guide groove 11. The limit blocks 12 extend into the interior of the limit grooves 13 and slide in connection with their inner walls.
[0026] Specifically, the inner wall of the sleeve 2 at the end away from the second flange 16 is provided with an inner opening 15. The end of the insertion tube 18 is fixedly installed with a second sealing gasket 19 by gluing. The insertion tube 18 is inserted into the sleeve 2 and is in close contact with the inner opening 15 through the second sealing gasket 19. The end of the sleeve 2 near the second flange 16 is fixedly installed with a first sealing gasket 3 by gluing. The first sealing gasket 3 is in close contact with the inner wall of the outer groove 17 by gluing.
[0027] Specifically, a gasket 4 is fixedly installed on the side of the first flange 1 near the second flange 16. The gasket 4 is sleeved on the outer periphery of the sleeve 2 and fixedly connected to it.
[0028] In this embodiment, during use, the insert 18 on the second flange 16 is inserted into the sleeve 2 on the first flange 1. The second sealing gasket 19 is used to ensure tight contact between the sleeve and the inner opening 15 inside the sleeve 2, achieving a bottom-layer seal. Then, the first sealing gasket 3 at the end of the sleeve 2 is in tight contact with the inner wall of the outer groove 17, causing it to be misaligned with the second sealing gasket 19 to form a second layer of seal. When the first flange 1 and the second flange 16 are joined, the gasket 4 forms a third layer of seal. Finally, the flipping clamping plate 5 is used to engage the clamping plates 5 on the first flange 1 and the second flange 16, so that the first... The retaining plate 5 on flange 1 engages with the retaining groove 14 on the second flange 16, and the retaining plate 5 on the second flange 16 engages with the retaining groove 14 on the first flange 1. Then, by rotating the knob 6, the screw 7 is driven to rotate. The screw 7 and the thread in the thread groove 9 form a drive, thereby driving the threaded sleeve 8 to move and engage with the inside of the retaining groove 14, thus forming an engagement. At the same time, the guide post 10 and the guide groove 11 limit the threaded sleeve 8 to ensure the stability of the threaded sleeve 8, thereby ensuring the stability of the engagement state with the retaining groove 14, and thus ensuring the stability between the first flange 1 and the second flange 16.
