[0020] Please see Figures 1-5 This utility model provides a technical solution: a flange pipe seat with a reinforced sealing structure, including: a flange 1, a sleeve 2, and a saddle head 3; the bottom end of the flange 1 is connected to the sleeve 2, the end of the sleeve 2 is fixedly sleeved with a convex ring 4, the bottom end of the sleeve 2 is connected to a threaded pipe 5, the end of the saddle head 3 is provided with an installation groove 6, and the bottom end of the installation groove 6 is provided with a threaded groove 7 that is threadedly connected to the threaded pipe 5; the saddle head 3 is connected to the sleeve 2 through an auxiliary component.

[0021] The threaded pipe 5 at the bottom of the flange sleeve 2 extends into the mounting groove 6 and is threadedly connected to the threaded groove 7 to achieve the initial connection of the saddle head 3, which is set at the end of the sleeve 2.

[0022] The sealing gasket 8 in the auxiliary component is embedded in the mounting groove 6, the convex ring 4 is embedded in the mounting groove 6 to compress the sealing gasket 8, the boss 9 is symmetrically arranged on the peripheral wall of the sleeve 2, the side wall of the boss 9 is provided with a moving groove 10, and the two side walls of the moving groove 10 are symmetrically provided with sliding grooves 11.

[0023] After the sealing gasket 8 is embedded in the mounting groove 6, as the threaded pipe 5 is inserted into the inner ring of the sealing gasket 8 and tightly connected to the threaded groove 7, the convex ring 4 is inserted into the mounting groove 6 and moves downward to press the sealing gasket 8, ensuring the sealing effect of the connection between the saddle head 3 and the sleeve 2.

[0024] A movable plate 12 is snapped into the movable groove 10. Slider 13s are symmetrically connected to the two side walls of the movable plate 12. The slider 13s are movably snapped into the sliding groove 11. An L-shaped locking plate 14 is connected to the bottom wall of the movable plate 12. An annular groove 15 is opened on the peripheral wall of the saddle head 3. The L-shaped locking plate 14 is snapped into the annular groove 15.

[0025] The slider 13 is movable and engaged within the slide groove 11 to assist the movement of the guide plate 12, allowing the L-shaped clamping plate 14 to move and engage with the annular groove 15 on the saddle head 3. This further enhances the connection stability between the saddle head 3 and the sleeve 2, preventing the threaded connection between the threaded pipe 5 and the threaded groove 7 from becoming loose.

[0026] The movable plate 12 is provided with a dial plate groove 16. The two ends of the guide post 17 are connected to the side wall of the dial plate groove 16. The dial plate 18 is symmetrically and movably engaged in the dial plate groove 16. The dial plate 18 is movably sleeved with the guide post 17.

[0027] The guide post 17 is sleeved with a spring 19, and the two ends of the spring 19 are engaged with the lever plate 18. The side wall of the boss 9 is symmetrically connected with a limiting protrusion 20, and the lever plate 18 is engaged with the limiting protrusion 20.

[0028] The compressed spring 19 provides a thrust to the dial plate 18 as it moves to the end of the dial plate groove 16, and the limiting protrusion 20 engages with the limiting dial plate 18 to fix the position of the moving plate 12.

[0029] A limiting plate 21 is rotatably connected to the side wall of the protrusion 9. The two side walls of the limiting plate 21 are engaged with the lever plate 18. A buckle groove 22 is provided on the end wall of the limiting plate 21. An elastic buckle 23 is connected to the side wall of the moving plate 12. The elastic buckle 23 is engaged with the buckle groove 22.

The elastic buckle 23 is engaged with the buckle groove 22 to fix the position of the limiting plate 21.

[0031] Working principle: After the sealing gasket 8 is fitted into the mounting groove 6, the threaded pipe 5 at the bottom of the flange sleeve 2 extends into the mounting groove 6 and is fitted into the inner ring of the sealing gasket 8 until the threaded pipe 5 is tightly connected to the threaded groove 7, so that the convex ring 4 is fitted into the mounting groove 6 and presses the sealing gasket 8, ensuring the sealing effect of the connection between the saddle head 3 and the sleeve 2. Then, the two levers 18 move in opposite directions to compress the spring 19, which in turn moves the slider 13 to the end of the slide groove 11. After that, the levers 18 are released, and the spring 19 returns to its original position, pushing the levers 18 to the end of the lever groove 16. At this time, the limiting convex plate 2 is stopped. The 0-clamping limiting plate 18 is used to fix the position of the moving plate 12, so that the L-shaped clamping plate 14 moves with the moving plate 12 and is fixed in position after being clamped with the annular groove 15 on the saddle head 3, thereby preventing the threaded connection between the threaded pipe 5 and the threaded groove 7 from loosening. The limiting plate 21 is rotated to cooperate with the elastic buckle 23 and the buckle groove 22 to fix the position of the limiting plate 21. At this time, the limiting plate 21 is clamped between the two plates 18 to clamp the limiting plate 18, thus completing the connection between the flange pipe seat sleeve 2 and the saddle head 3. The operation is simple and further improves the stable sealing connection between the flange pipe seat saddle head 3 and the sleeve 2.
