Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The technical solution provided by the present invention is as follows: As Figure 1 and Figure 4 shown, in this embodiment, a multi-layer composite structure anti-theft bottle cap includes a cap body 1. A safety structure 2 is fixedly connected below the cap body 1. A positioning cylinder 4 is fixedly connected inside the cap body 1. A waterproof pad 5 is provided inside the cap body 1. An auxiliary ring 6 is fixedly connected above the waterproof pad 5. A clamping structure 3 is provided inside the cap body 1. The clamping structure 3 is connected to the auxiliary ring 6. The waterproof pad 5 is clamped with the clamping structure 3. The clamping structure 3 includes a fixing rod 301, an installation ring 302 and a limiting block 303. A positioning rod 304 is fixedly connected inside the installation ring 302. A limiting groove 306 is opened outside the fixing rod 301. A bolt 305 is threadedly connected inside the installation ring 302.

[0021] As Figure 1 and Figure 2 shown, the cap body 1 and the positioning cylinder 4 are integrally formed. The waterproof pad 5 overlaps below the positioning cylinder 4. Threads are provided inside the cap body 1. The safety structure 2 includes a sleeve 201 and a connecting ring 203. The connecting ring 203 is fixedly connected below the cap body 1. The connecting ring 203 and the cap body 1 are integrally formed. A plastic part 202 is connected below the connecting ring 203. The lower part of the plastic part 202 is fixedly connected to the upper part of the sleeve 201.

[0022] By setting the positioning cylinder 4 and the plastic part 202, since the cap body 1 and the safety structure 2 are connected to the bottle mouth, and the sleeve 201 will contact the bottle mouth. Once the bottle cap is illegally opened, the plastic part 202 will break accordingly. Once it is opened, the plastic part 202 will break, making the bottle cap unable to be restored with the plastic part 202, effectively preventing forgery, illegal opening and product tampering. When the waterproof pad 5 is connected to the cap body 1, the waterproof pad 5 will overlap with the positioning cylinder 4, so that the positioning cylinder 4 plays a certain limiting role on the waterproof pad 5, avoiding the position of the waterproof pad 5 from shifting during fixation.

[0023] As Figure 3 and Figure 4 shown, the fixing rod 301 is fixedly connected below the cap body 1. The installation ring 302 is clamped inside the cap body 1.

The limiting block 303 overlaps inside the limiting groove 306. The fixing rod 301 is clamped inside the waterproof pad 5.

[0024] By providing the limit groove 306 and the limit block 303, when the waterproof pad 5 is connected to the fixing rod 301, the auxiliary ring 6 above the waterproof pad 5 will slide through the limit block 303 in the limit groove 306, and then the limit block 303 will be lapped in the groove of the limit groove 306, so that the limit groove 306 and the limit block 303 play a certain positioning role in fixing the waterproof pad 5, avoiding the phenomenon of collision when the positioning rod 304 is clamped with the limit block 303, and avoiding the phenomenon of loosening when the waterproof pad 5 is fixed.

[0025] The utility model provides a multi-layer composite structure anti-theft bottle cap, and the specific working principle is as follows:

[0026] When the bottle cap is in use, the waterproof pad 5 can slide through the limit block 303 in the auxiliary ring 6 in the limit groove 306. When the waterproof pad 5 is attached to the positioning cylinder 4, it drives the waterproof pad 5 to rotate. After the limit block 303 rotates, it will be lapped in the limit groove 306. The installation ring 302 is inserted through the positioning rod 304 with the cover body 1 and the fixing rod 301. After the positioning rod 304 is inserted, it will be clamped with the limit block 303, and the installation ring 302 will be threadedly connected to the cover body 1 through the bolt 305, and then the cover body 1 and the safety structure 2 will be connected to the bottle mouth.
