The outer side surface of the circular truncated cone-shaped glass ring 20 is in the shape of an inclined surface, and the inner side surface is in the shape of a straight surface, which is more advantageous for meeting the requirements of fixing and sealing water. For the sealing ring 201 located between the lower end surface of the glass ring 20 and the upper end surface of the cup body 10, the glass ring 20 is preferably a spring ring or a silica gel ring, which is convenient to implement. In the embodiment, four clamping protrusions 30 are adopted, which are uniformly arranged on the outer side wall of the cup mouth of the cup body 10, which is convenient for the clamping protrusions 30 to be clamped in the clamping grooves 11, so that the self-locking glass water sealing cup cover 50 is more stable in connection with the cup body 10, and the rotation of the inner cover 1 is avoided. For the pressing ring 202, it can also not be used (for example Figures 25 to 28 As shown).

[0069] As shown, Figures 1 to 28As shown, first, the self-locking device 3 in the self-locking glass water sealing cup cover 50 is in the initial loosening state (i.e., the radial expansion state), when the self-locking glass water sealing cup cover 50 is placed on the cup mouth of the cup body 10, the evenly distributed clamping convex points 30 on the outer side wall of the cup mouth of the cup body 10 correspond to fall into the clamping grooves 11 on the inner side wall of the inner cover 1, at this time, the inner cover 1 cannot rotate at the cup mouth of the cup body 10, then rotate the outer shell 6 (clockwise), the outer shell 6 will drive the inner cover 2 to rotate together (clockwise), the recess 21 on the inner side wall of the inner cover 2 contacts the clamping hook 32 to become the protrusion 22 on the inner side wall of the inner cover 2 contacts the clamping hook 32, so as to push the clamping hook 32 to perform lever movement on the inner cover 1, the lower part of the clamping hook 32 moves to the center position of the inner cover 1, and the lower part of all the clamping hooks 32 changes from radial expansion to radial contraction, so that the clamping hook 32 is clamped in the locking groove 40 of the cup body 10, so that the self-locking glass water sealing cup cover 50 is tightly covered on the cup mouth of the cup body 10, and the glass plate 45 in the glass water sealing element 4 moves downward to be sealed with the glass ring 20 on the cup body 10 by the principle of water sealing, so that the self-locking glass water sealing cup cover 50 and the cup body 10 will not leak water and air, avoiding the need to contact plastic in the prior art, from adding water to drinking water, the whole process is free of plastic contact, realizing zero pollution, this kind of using the properties of glass, after the glass plate 45 and the glass ring 20 contact, they can mutually self-absorb to form a sealed exhaust sealing water, which is conducive to more tightly covering the self-locking glass water sealing cup cover 50 on the cup mouth of the cup body 10, and when the outer shell 6 is reversely rotated (counterclockwise), the outer shell 6 will drive the inner cover 2 to reversely rotate together (counterclockwise), the protrusion 22 on the inner side wall of the inner cover 2 contacts the clamping hook 32 to become the recess 21 on the inner side wall of the inner cover 2 contacts the clamping hook 32, at this time, the clamping hook 32 performs lever movement on the inner cover 1, the lower part of all the clamping hooks 32 changes from radial contraction to radial expansion, at this time, the self-locking device 3 returns to the initial state, so that the clamping hook 32 is separated from the locking groove 40 of the cup body 10, and the glass plate 45 in the glass water sealing element 4 can be reset under the action of the resilience of the reset member 47 or the resilient body 48, which is conducive to the reset of the glass plate 45, so that the self-locking glass water sealing cup cover 50 can be removed from the cup mouth of the cup body 10.

[0070] The standard parts used in the present application file can be purchased from the market, and the specific connection mode of each part adopts the conventional means of sealing ring and spring in the prior art, which will not be described in detail here.
