[0030] The present application embodiment discloses a leakage-proof structure for a travel cup cover. Figure 1 , Figure 2 and Figure 3, comprising a cup body 1, a sleeve 3 arranged at the water inlet and outlet on the top of the cup body 1, and a bell mouth 5 arranged at the water inlet and outlet on the top of the sleeve 3, the upper and lower sides of the inner channel 4 are respectively connected with the bell channel 6 on the bell mouth 5 and the water inlet and outlet of the cup body 1, the outer side of the sleeve 3 is screwed with a cup cover body 8, the inner bottom wall of the cup cover body 8 is provided with a mounting groove, the inside of the mounting groove is provided with a matching mounting plate 13, the inner bottom wall of the mounting groove is provided with a threaded groove, and the surface of the mounting plate 13 is fixedly connected with a sealing column 15, The sealing column 15 is screwed into the inner channel 4, and has a primary water leakage prevention effect. The diameter of the limiting ring 14 is smaller than the maximum outer diameter of the bell mouth 5. The outer side of the sealing column 15 and the inner bottom wall of the cup cover body 8 and the outer side of the mounting groove are provided with a first sealing gasket. When the cup cover body 8 is screwed, the bell mouth 5 can be screwed into the interior of the cup cover body 8 and abut against the first sealing gasket, thereby having a secondary water leakage prevention effect. A second sealing gasket is provided at the edge of the bottom side of the cup cover body 8, so that when the cup cover body 8 is screwed;
[0031] The second sealing gasket can be tightly pressed against the cup body 1, and has a three-level anti-leakage effect. A circular groove 20 is opened in the middle of the surface of the sealing column 15, and a plug hole 21 is opened in the middle of the inner bottom wall of the circular groove 20. The plug hole 21 extends to the surface of the mounting plate 13 at one end away from the circular groove 20. A bolt rod 22 is inserted into the inside of the plug hole 21. The bolt rod 22 is a hexagonal bolt rod 22. The bolt rod 22 is screwed and screwed out from the inside of the threaded groove, thereby releasing the fixation of the sealing column 15, and the mounting plate 13 can be removed from the inside of the mounting groove, and the sealing column 15 can be taken out from the inside of the cup cover body 8 for replacement. The bolt rod 22 is threadedly inserted into the inside of the threaded groove.
[0032] See also Figure 2 A fixing ring 16 is fixedly connected to the middle part of the surface of the sealing column 15, and a cover body 18 is screwed on the outer side of the fixing ring 16, and the cover body 18 is screwed on the outer side of the fixing ring 16 to prevent water from entering the circular groove 20 and the inside of the plug hole 21. A rubber pad 17 is fixedly connected to the surface of the fixing ring 16. The rubber pad 17 improves the sealing between the cover body 18 and the sealing column 15. A rubber pad 2 19 is fixedly connected to the side of the cover body 18 close to the sealing column 15. The rubber pad 2 19 further improves the sealing between the cover body 18 and the sealing column 15. A limiting ring 14 is sleeved on the outer side of the sealing column 15. During installation, the limiting ring 14 abuts against the inner bottom wall of the cup cover body 8. The limiting ring 14 is fixedly connected to the mounting plate 13. A rubber gasket is arranged on the outer side of the mounting plate 13. The rubber gasket improves the sealing between the limiting ring 14 and the inner bottom wall of the cup cover body 8 to prevent water from entering the inside of the mounting groove. The rubber gasket is fixedly connected to the limiting ring 14.
[0033] See also Figure 1An annular groove 9 is provided on the outer side of the cup cover body 8, and an annular plate 10 is rotatably connected inside the annular groove 9. When the cup cover body 8 is screwed, the annular plate 10 cooperates with the annular groove 9 to rotate inside the annular groove 9, thereby preventing the connecting rope 7 from being entangled around the outer side of the cup cover body 8. A connecting rope 7 is fixedly connected between the annular plate 10 and the cup body 1, and the connecting rope 7 connects the cup cover body 8 together to prevent the cup cover body 8 from falling off.
[0034] See also Figure 1 The outer side of the cup body 1 is provided with a non-slip and heat-insulating sleeve 2, which increases the friction when holding the cup body 1 and can also play a heat-insulating role. The bottom side of the cup body 1 is fixedly connected with a non-slip and wear-resistant pad, which increases the friction of the cup body 1 when placed on the surface of an object. The top of the cup cover body 8 is fixedly connected with a circular plate 12, and an arc-shaped carrying strap 11 is provided on the outer side of the circular plate 12. The arc-shaped carrying strap 11 is pin-connected to the circular plate 12, and the arc-shaped carrying strap 11 is used to facilitate carrying the cup body 1.
[0035] The implementation principle of the embodiment of the present application is: screw the bolt rod 22 and screw the bolt rod 22 out from the inside of the thread groove, thereby releasing the fixing of the sealing column 15, and then the mounting plate 13 can be removed from the inside of the mounting groove, and the sealing column 15 can be taken out from the inside of the cup cover body 8 for replacement;
[0036] The cooperation between the limiting ring 14 and the rubber gasket prevents water from entering the interior of the installation groove, and the cooperation between the rubber pad 17 and the rubber pad 2 19 increases the sealing between the cover body 18 and the sealing column 15, preventing water from entering the interior of the circular groove 20 and the plug hole 21.
[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
