An unlocking buckle 3 is provided on the outer side of the first self-locking block 1 and the second self-locking block 2, and an anti-slip pattern 12 is integrally formed on the outer side of the unlocking buckle 3, and a convex block 13 is integrally formed on the inner side of the unlocking buckle 3, and an arc surface 14 is provided on one end of the convex block 13. A through hole is provided on the buckle 5. When in use, only the first self-locking block 1 and the second self-locking block 2 need to be placed on the outer side of the bottle mouth connecting cover, and the convex ring on the outer side of the connecting cover and the bottle mouth is completely placed on the first self-locking block 1 and the first The first self-locking block 1 and the second self-locking block 2 are connected to each other so that the docking column 4 is plugged into the docking hole 7 to play a guiding role, and the guide surface 6 of the buckle 5 is in contact with the contact surface 8. The buckle 5 is deformed and deformed inwardly until one end of the buckle 5 is placed in the slot 9. The buckle 5 rebounds and the buckle 5 is buckled with the slot 9, thereby completing the assembly of the first self-locking block 1 and the second self-locking block 2. The assembled first self-locking block 1 and the second self-locking block 2 are rotatably connected to the bottle cap, and there is a gap with the outside of the bottle cap, so that it cannot pass. By twisting the first self-locking block 1 and the second self-locking block 2, the bottle cap is prevented from being opened and the daily necessities in the bottle are prevented from being stolen. When the bottle cap needs to be opened to replenish the daily necessities in the bottle, the unlocking buckle 3 only needs to be inserted into the outer side of the second self-locking block 2 so that the raised block 13 is inserted into the through groove 10.

[0021] Furthermore, the outer wall size of the docking column 4 matches the inner wall size of the docking hole 7 , and there are four docking holes 7 and four docking columns 4 .

[0022] Furthermore, the guide surface 6 is an inclined surface structure, and two buckles 5 are provided.

[0023] Furthermore, two through grooves 10 are provided, and anti-slip grooves 12 are provided at both ends of the unlocking buckle 3 .

[0024] Furthermore, two protruding blocks 13 are provided.

[0025] Example 2

[0026] Different from the above embodiment, please refer to Figure 5 A film 11 is glued to the inner end of the through groove 10. When producing the product, the first self-locking block 1 and the second self-locking block 2 are assembled together. When selling, it can be observed whether the film 11 is damaged to determine whether it is opened. The buckle 5 does not contact the film 11, and the film 11 is made of PE material.

[0027] Working principle: When in use, only the first self-locking block 1 and the second self-locking block 2 need to be placed on the outside of the bottle mouth connection cover, and the convex rings on the connection cover and the outside of the bottle mouth are completely placed on the inside of the first self-locking block 1 and the second self-locking block 2, so that the first self-locking block 1 and the second self-locking block 2 will not fall off, and are connected to each other, so that the docking column 4 is plugged into the docking hole 7, which plays a guiding effect, and the guide surface 6 of the buckle 5 is in contact with the contact surface 8, and the buckle 5 is deformed through the guide surface 6 and the contact surface 8, and deformed inwardly until one end of the buckle 5 is placed in the card slot 9, the buckle 5 rebounds, and the buckle 5 is buckled with the card slot 9, thereby completing the first The self-locking block 1 and the second self-locking block 2 are assembled. After assembly, the first self-locking block 1 and the second self-locking block 2 are rotatably connected to the bottle cap, and there is a gap with the outside of the bottle cap, so that the bottle cap cannot be opened by twisting the first self-locking block 1 and the second self-locking block 2, and the daily necessities in the bottle cannot be stolen. When the bottle cap needs to be opened and the daily necessities in the bottle need to be replenished, the unlocking buckle 3 only needs to be inserted into the outside of the second self-locking block 2 so that the protruding block 13 is stuck in the through groove 10, and then the two ends of the unlocking buckle 3 are pressed. The protruding block 13 will push the buckle 5 out of the slot 9, thereby separating the first self-locking block 1 and the second self-locking block 2, and thus opening the bottle cap.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the implementation rules without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
