[0040] like Fig.10 and Fig.11 As shown, the main cover comprises a first main cover body 1-1 and a second main cover body 1-2. The second main cover body is arranged at a higher level than the first main cover body. The top surface of the first main cover body protrudes upward to form a boss 1.3 higher than the second main cover body, the coil is arranged in the boss, the top surface of the second main cover body is provided with a boss 1.4, and the lock core assembly is arranged in the boss.
[0041] like Fig.12 and Fig.13 As shown, the sliding cover comprises a first sliding cover body 2-1 and a second sliding cover body 2-2, and the first sliding cover body is slidably positioned in the second main cover body. When the main cover and the sliding cover are closed, the first sliding cover body is completely inserted into the second main cover body, and the second sliding cover body is located below the first main cover body. The second sliding cover body and the second main cover body are combined to form a round cover that can surround the top of the can.
[0042] The main cover is provided with a main cover slot a at the bottom, and the sliding cover is provided with a sliding cover slot b matching the main cover slot at the bottom. When the main cover and the sliding cover are closed, the main cover slot and the sliding cover slot respectively clamp the top convex edge 9-1 of the can 9 from both sides, so that the anti-theft label is fixed to the can.
[0043] The second main cover body is semicircular, and a main cover baffle 1.1 hanging downward is provided on one side of its arc edge. The main cover baffle is curved in an arc shape, and a plurality of main cover hooks 1.2 arranged along the arc length direction of the inner wall are provided on the inner side of the main cover baffle.

[0046] The conventional method of fixing the coil is to glue it, but the vibration during transportation often causes degumming, and the coils of different models are of different sizes, and the bonding methods are also different, which leads to a complicated production process. The main cover is provided with a limiter 4 for fixing the coil, and the coil is pressed and fixed in the main cover. The limiter includes a connecting part 4.1 and a pressing plate 4.2. The connecting part has a countersunk hole, and the connecting part covers the first column 1.7 (with a screw hole) on the bottom surface of the second main cover body. The countersunk screw 11 passes through the countersunk hole and engages with the screw hole to fix the connecting part to the first column. The pressing plate presses the coil to be fixed in the boss of the first main cover body. The limiter can meet the installation requirements of coils of various sizes, so that the coil is firmly fixed in the main cover, ensuring the connection strength and simplifying the production process. In order to prevent the limiter from rotating, the connecting part has a limiting notch 4.3, and the bottom surface of the second main cover body is provided with a limiting plate 1.7.1 that cooperates with the limiting notch.
[0047] The top surface of the boss of the main cover is located at the same horizontal plane as the top surface of the boss, and two symmetrically arranged positioning grooves are provided on the boss. The top surface of the boss is provided with two pairs of protrusions 1.5, and a certain spacing is maintained between each pair of protrusions to form the positioning grooves. The position, height, spacing of the protrusions and the size of the boss and the protrusion are determined according to the shape and size of the can.
[0048] like Fig.16 As shown, cans can be stacked layer by layer on the anti-theft label, and the bottom convex ring 9-2 of the can is not only mounted on the convex column, but also stuck in the positioning groove, so that the can above the anti-theft label is not easy to slip, meeting the stacking requirements.
[0049] The lock core assembly includes a lock head 5 and a lock core spring 6 that pushes the lock head. The boss is a hollow structure, and the top cover 7 is installed in the inner cavity of the boss. The lock head can be vertically slidably positioned between the boss and the top cover, and the lock core spring is arranged between the top cover and the lock head. The first slide cover body of the slide cover is provided with a lock hole 2.3 for the lock head to be inserted. The right end of the first slide cover body ( Figure 8 The left end) is provided with an inclined surface 2.4 for squeezing the lock head.
[0050] A guide structure for guiding the sliding of the sliding cover and a limit structure for controlling the sliding stroke of the sliding cover are also provided between the main cover and the sliding cover. The guide structure and the limit structure are provided between the first sliding cover body and the second main cover body. The guide structure includes a slide groove 1.9 provided in the second main cover body and sliders 2.7 provided on both sides of the first sliding cover body and cooperating with the slide groove. The limit structure includes a strip hole 2.5 provided on the first sliding cover body and a pan head screw 12 passing through the strip hole and fixed to the second main cover body. A second column 1.8 (with a screw hole) is provided on the bottom surface of the second main cover body, and the pan head screw passes through the strip hole and engages with the screw hole. The length direction of the strip hole is parallel to the sliding direction of the sliding cover.
[0051] A return spring 10 is also provided between the main cover and the sliding cover. When unlocking, the main cover and the sliding cover are automatically separated under the push of the return spring. Two grooves 2.8 are provided in the first sliding cover body, and a return spring is installed in each groove. One end of the return spring presses against the inner wall of the groove, and the other end presses against the inner wall of the second main cover body.
[0052] In order to ensure the connection strength between the main cover and the sliding cover when locked, and to prevent the main cover card slot and the sliding cover card slot from being misaligned due to external force, which may cause the anti-theft function to fail, a docking structure is also required between the main cover and the sliding cover. The docking structure includes a card slot 1.6 provided at both ends of the main cover baffle and a card block 2.6 provided at both ends of the sliding cover baffle. When the main cover and the sliding cover are closed and locked, the card block is inserted into the card slot, so that the two ends of the main cover baffle and the two ends of the sliding cover baffle are docked left and right to form a whole, thereby ensuring the connection strength.
