[0041] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components, orientations, and references (e.g., up, down, left, right, etc.) relevant to the present invention and are intended only to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0042] like Figures 1-11 As shown, a can anti-theft tag is affixed to the top of the can 6 to lock the can 6 and thus prevent theft, comprising:

[0043] The fixed cover includes an upper cover 1 and a lower cover 2 that are snapped together. The upper cover 1 covers the lower cover 2, and the two are enclosed to form an insertion cavity with at least a transverse opening.

[0044] The movable cover 3 is movably disposed in the insertion cavity to open or close the can 6. When the movable cover 3 is inserted into the insertion cavity laterally, the can 6 can be closed. When the movable cover 3 is pulled out of the insertion cavity laterally, the can 6 can be opened.

[0045] The device includes an elastic locking piece 4, which extends into the locking groove 306 to lock the movable cover 3 to the fixed cover, or deforms elastically under magnetic force to disengage from the locking groove 306 and unlock the movable cover 3 from the fixed cover. Initially, the elastic locking piece 4 extends from the fixed cover into the movable cover 3 to lock it. When unlocking is required, a magnetic unlocking device attracts the elastic locking piece 4, causing it to retract from the movable cover 3. At this point, the movable cover 3 can slide laterally to open the can 6. This application utilizes a fixed cover and a pull-out movable cover 3 to open or close the can 6. The fixed cover and movable cover 3 are longitudinally distributed, and the elastic locking piece 4 cooperates with the locking groove 306 to lock and unlock the movable cover 3. This design does not occupy additional lateral space, resulting in a simpler and more compact overall structure, significantly reducing packaging costs.

[0046] In some examples, a reset elastic element 5 is provided between the movable cover 3 and the fixed cover to push the movable cover 3 out when it is unlocked. When the movable cover 3 is in the locked state, the reset elastic element 5 is in the compressed state. When the movable cover 3 is unlocked, the reset elastic element 5 is reset so that the movable cover 3 can be pushed out.

[0047] In some examples, the lower cover 2 has an insertion groove 201 inside, which is longitudinally through and has a transverse opening, and is roughly C-shaped. The upper cover 1 seals the top of the insertion groove 201 to form the insertion cavity. The groove wall of the insertion groove 201 protrudes to form a slide 202. The movable cover 3 has a sliding part 301 that cooperates with the slide 202. The sliding part 301 and the slide 202 can guide the sliding direction of the movable cover 3 on the one hand, and the slide 202 can support the movable cover 3 and limit its lower position on the other hand. At the same time, the upper cover 1 can limit the upper position of the movable cover 3, thereby limiting the position of the movable cover 3.

[0048] In some examples, the top of the lower cover 2 extends laterally to form a first extension 203, and the bottom of the movable cover 3 extends laterally to form a second extension 302 with a stepped surface between them. The stepped surface abuts against the first extension 203 to limit the insertion stroke of the movable cover 3. The first extension 203 covers the second extension 302, and the second extension 302 has an installation groove 303 for mounting the reset elastic member 5. The installation groove 303 has a first slot for the reset elastic member 5 to extend out. The lower cover 2 has a receiving groove opposite to the installation groove 303 and a second slot for the reset elastic member 5 to enter. One end of the reset elastic member 5 abuts against the bottom of the installation groove 303, and the other end abuts against the bottom of the receiving groove.

[0049] In some examples, a stepped surface 601 is formed at the top of the tank body 6, and a first hook 204 and a second hook 305 are formed at the bottom of the fixed cover and the bottom of the movable cover 3, respectively, for hooking with the stepped surface 601. There are multiple first hooks 204 and second hooks 305, which are distributed at intervals along the circumference of the tank body 6. The fixed cover can be locked to the tank body 6 by the first hook 204 cooperating with the stepped surface 601, and the movable cover 3 can be locked to the tank body 6 by the second hook 305 cooperating with the stepped surface 601.

[0050] In some examples, a limiting pin 7 is installed on the upper cover 1, and the movable cover 3 is formed with a limiting groove 304 for the limiting pin 7 to be inserted to limit the travel of the movable cover 3. The limiting groove 304 is a horizontally extending waist-shaped groove. The upper cover 1 protrudes in the direction of the limiting groove 304 to form a protruding post 102 for the limiting pin 7 to be installed. A rib 104 connects the protruding post 102 and the positioning groove 101.

[0051] In some examples, the resilient locking piece 4 protrudes in the direction of the locking groove 306 to form a locking bar 401, which can further improve the locking force of the resilient locking piece 4.

[0052] In some examples, the number of elastic locking pieces 4 is at least one; in this embodiment, the number is two, both formed side by side on the connecting piece 8, and the connecting piece 8 is embedded in the upper cover 1. The bottom of the upper cover 1 has a recessed groove for the connecting piece 8 to be embedded, such as... Figure 11 As shown.

[0053] In some examples, the top of the upper cover 1 is recessed to form a positioning groove 101 for the unlocker to be inserted and positioned therein. When the unlocker is inserted into the positioning groove 101, the unlocker attracts the elastic locking piece 4 to disengage it from the locking groove 306.

[0054] In some examples, the upper cover 1 and the lower cover 2 are respectively formed with a protruding snap-fit ​​portion 103 and a snap-fit ​​groove 205 for the snap-fit ​​portion 103 to be inserted into. That is, the snap-fit ​​portion 103 can be located on the upper cover 1 or the lower cover 2, and the snap-fit ​​groove 205 is located on the other. There are multiple snap-fit ​​portions 103 and snap-fit ​​grooves 205, and they correspond one-to-one. Each snap-fit ​​portion 103 is snapped into its corresponding snap-fit ​​groove 205 to fix the upper cover 1 and the lower cover 2.

[0055] The above description, based on the preferred embodiments of this utility model, provides inspiration. Through this explanation, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification but must be determined according to the scope of the claims.
