[0023] A bolt 24 is threadedly connected inside the threaded hole 22. Using the bolt 24 for connection is convenient for disassembly and also convenient for locking. A pressing rod 27 is fixedly connected to the bottom of the connecting rod 26, and the pressing rod 27 is in contact with the surface of the main body 1 of the easy-open lid.

[0024] There are three groups of both the connecting rod 26 and the pressing rod 27 and they are distributed in a circumferential array. A notch 29 is opened at the bottom of one of the pressing rods 27. One of the pressing rods 27 is provided with a notch 29, and the other two pressing rods 27 are in contact with the sealing cover on the surface of the main body 1 of the easy-open lid, playing a stabilizing effect.

[0025] Specifically, after the pull tab 4 of the easy-open lid rotates and fits with the main body 1 of the easy-open lid, rotate the disc 25 to make multiple connecting rods 26 and pressing rods 27 rotate until the notch 29 of one of the pressing rods 27 fits on the upper surface of the pull tab 4 of the easy-open lid.

Subsequently, pull the pull tab 4 of the easy-open lid to lift the entire sealing cover.

[0026] Embodiment 2:

[0027] Please refer to the attached Figure 1 -attached Figure 5 On the basis of Embodiment 1, it is further obtained that a sealing cover is provided on the surface of the main body 1 of the easy-open lid, and a pull tab 4 of the easy-open lid is provided on the surface of the sealing cover. A sealing gasket is provided at the connection between the pull tab 4 of the easy-open lid and the sealing cover. A cavity 5 is formed inside the main body 1 of the easy-open lid.

The buffer elastic action of the buffer springs 7 enables them to withstand the impact pressure on the main body 1 of the easy-open lid and keep the shape of the lid stable, preventing the main body 1 of the easy-open lid from being deformed due to collision during transportation.

[0031] Working principle of the present utility model: The present utility model is a self-sealing and easy-to-open lid structure. First, rotate the self-sealing mechanism 3 to disengage the pressing rod 27 from the pull ring 4 of the easy-to-open lid, and then the easy-to-open lid opening can be opened. When sealing is required, rotate the pull ring 4 of the easy-to-open lid to fit it with the sealing lid on the surface of the easy-to-open lid body 1. Rotate the disc 25 to make multiple connecting rods 26 and pressing rods 27 rotate until the notch 29 of one of the pressing rods 27 fits on the upper surface of the pull ring 4 of the easy-to-open lid. Subsequently, adjust the rotating block 28 to screw the bolt 24 into the threaded hole 22, so that the bottom of the disc 25 fits with the sealing lid on the surface of the easy-to-open lid body 1, and the surface of the disc 25 is fitted with the rotating block 28 to complete the fixation, thereby realizing the sealing at the pull ring 4 of the easy-to-open lid. Inside the cavity 5, there are multiple buffer protection devices composed of mounting blocks 6 and buffer springs 7. The buffer elastic effect of the buffer springs 7 enables them to withstand the impact pressure on the easy-to-open lid body 1 and keep the shape of the lid stable, avoiding the collision deformation of the easy-to-open lid body 1 during transportation.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
