[0002] Bottle caps are used for sealing bottles and merchant lottery activities. According to different functions, there are bottle caps with different shapes and different operation methods. The structure of a common safety bottle cap is as follows: it includes a cap body, and the inner side wall of the cap body is provided with threads; when in use, rotating the bottle cap in the clockwise direction can screw the bottle cap tightly with the bottle body, and rotating the bottle cap in the counterclockwise direction can loosen and separate the bottle cap from the bottle body; the screwing structure of the bottle cap and the bottle body that has been opened is extremely easy to be opened.

[0003] Currently, the existing safety bottle caps for encapsulating items to be tested such as medicines, chemicals, and medical test reagents that should not be opened casually can only play a sealing role and do not have the functions of opening and closing counting and recording relevant information of sealing, so the safety is relatively low.

[0004] Therefore, a safety bottle cap capable of opening and closing counting based on RFID is proposed. Summary of the Invention

[0005] In view of this, the present invention provides a safety bottle cap capable of opening and closing counting based on RFID to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0006] The technical solution of the present invention is realized as follows: A safety bottle cap capable of opening and closing counting based on RFID includes a cap body. The top of the cap body is movably connected with a sealing cap through a rotating shaft. A contact sensor is fixedly connected inside the cap body, and the inner side of the contact sensor contacts the outer side of the sealing cap. A fixing mechanism is arranged at the bottom of the cap body. The fixing mechanism includes a rotating shaft, a fixing ring, a bolt, and a nut. The top of the rotating shaft is movably connected to the bottom of the cap body. The inner side of the fixing ring is fixedly connected to the outer side of the rotating shaft. The rear side of the bolt penetrates to the rear side of the fixing ring, and the nut is threadedly connected to the surface of the bolt.

[0007] Further preferably, a protective pad is fixedly connected to the inner side of the fixing ring, and the material of the protective pad is soft rubber.

[0008] Further preferably, friction blocks are arranged on the outer side of the cap body, and a signal transmitting module and an intelligent counter are arranged inside the contact sensor.

[0009] Further preferably, a cavity is formed inside the cover body, and a positioning mechanism is arranged inside the cavity. The positioning mechanism includes a pull rod, a positioning rod and a compression spring. The front side of the pull rod penetrates through the cavity and extends to the front side of the cover body. The front side of the positioning rod is fixedly connected to the rear side of the pull rod. The top of the compression spring is fixedly connected to the bottom of the positioning rod, and the bottom of the compression spring is fixedly connected to the inside of the cavity. The top of the positioning rod penetrates into the inside of the sealing cover.

[0010] Further preferably, fixing grooves are formed on the surface of the sealing cover, and the top of the positioning rod is movably connected to the inside of the fixing grooves.

[0011] Further preferably, a limiting block is fixedly connected to the inside of the cavity, and the limiting block is sleeved on the surface of the positioning rod.
