[0020] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] Reference Figures 1-8As shown, the adjustable anti-theft device for canned goods of this utility model includes a first housing 1, a second housing 2, an EAS frequency element 3, a first latching mechanism 4, a second latching mechanism 5, an adjustment mechanism 6, and a locking mechanism 7. The EAS frequency element is fixedly disposed in the second housing; the first latching mechanism is fixedly disposed inside the first housing; the second latching mechanism is fixedly disposed inside the second housing; the adjustment mechanism is disposed on the first housing and the second housing; the locking mechanism is disposed on the first housing and the second housing. The EAS frequency element is existing technology. When the can passes through the EAS access control antenna system, the EAS access control antenna system will emit an audible and visual alarm due to the EAS frequency element, reminding the user that the can has been stolen. The first and second latching mechanisms work together to engage with the rolled edge step on the top of the can, fixing the first and second shells to the top of the can and preventing criminals from opening the can directly inside the store. This, combined with the EAS frequency element, provides an anti-theft function. The adjustment mechanism can adjust the distance between the first and second shells, and consequently, the distance between the first and second latching mechanisms, adapting to cans of different diameters. For retailers, this eliminates the need to purchase anti-theft devices of various diameters, and for manufacturers, it eliminates the need to produce anti-theft devices of multiple diameters, saving costs. The locking mechanism locks the first and second shells, and consequently, the first and second latching mechanisms, ensuring the anti-theft device is fixed to the can.
[0022] Specifically, the first latching mechanism includes a first latching seat 41 and a plurality of first latching blocks 42; the first latching seat is fixedly disposed on the inner side of the first housing; the plurality of first latching blocks are fixedly disposed on the first latching seat; the inner side of the first latching block is provided with a slope; the bottom of the first latching block is narrower and the top is wider, forming a slope, and the wider part forms a step, which can fasten the rolled edge of the top of the can.
[0023] Specifically, the second latching mechanism includes a second latching seat 51 and a plurality of second latching blocks 52; the second latching seat is fixedly disposed on the inner side of the second housing; the plurality of second latching blocks are fixedly disposed on the second latching seat; the inner side of the second latching block is provided with a slope; the bottom of the second latching block is narrower and the top is wider, forming a slope, and the wider part forms a step, which can fasten the rolled edge of the top of the tank.
[0024] Specifically, the adjustment mechanism includes multiple first slide grooves 61, multiple second slide grooves 62, multiple first sliders 63, multiple spring holders 64, and multiple first springs 65. The multiple first slide grooves are symmetrically fixed on the first housing. The second housing can slide along the first slide grooves. The multiple second slide grooves are symmetrically fixed on the first housing. The multiple first sliders are symmetrically fixed on the second housing. The first sliders can slide along the second slide grooves. The multiple spring holders are symmetrically fixed on the second housing. One end of the first spring is fixed on the spring holder, and the other end is fixed on the first housing. One side of the first slider has an inclined surface, and the other side is a flat surface. The inclined surface facilitates the installation of the first slider into the second slide groove, that is, the second housing is inserted into the first housing. The second housing can slide along the first slide groove, and at this time, the first slider can slide in the second slide groove to realize the adjustment function. The flat surface at the other end of the first slider can prevent the first housing from detaching from the second housing during adjustment, which serves as a limiting function. During the adjustment of the first housing and the second housing, the first spring is compressed. After unlocking, the first spring will reset and automatically spring the second housing open.
[0025] Specifically, the locking mechanism includes an unlocking protrusion 71, a third sliding groove 72, a locking tooth post 73, a steel post 74, a second spring 75, and a locking rack 76; the unlocking protrusion is fixedly mounted on the first housing and protrudes from the first housing; the third sliding groove is fixedly mounted on the first housing and the unlocking protrusion; the locking tooth post is slidably mounted on the third sliding groove; the steel post is fixedly mounted on the top of the locking tooth post; one end of the second spring is fixedly mounted on the steel post and the other end is fixedly mounted on the unlocking protrusion; the locking rack is fixedly mounted on the second housing and can mesh with the locking tooth post. The locking pin has teeth at its bottom that can engage with the locking rack. One side of the teeth on the locking rack and the locking pin is inclined, and the other side is flat. During adjustment, the first and second housings can only be moved towards each other. The flat side prevents pulling the second housing from directly separating the locking pin and the locking rack. The second spring has a large elastic coefficient and is always in a compressed state. The second spring pushes the locking pin to engage with the locking pin, at which point the second housing cannot move. This, together with the first and second latching blocks, achieves a fixing effect, thus providing an anti-theft function.
[0026] Specifically, the first buckle seat and the first buckle block are arc-shaped; there is a gap between the plurality of first buckle blocks; the first buckle seat is an arc-shaped thin sheet.
[0027] Specifically, the second buckle seat and the second buckle block are arc-shaped; there is a gap between the plurality of second buckle blocks; the second buckle seat is an arc-shaped thin sheet.
[0028] In use, place the magnetic unlocking device at the top unlocking protrusion to attract the steel column upward, thereby causing the locking pin and locking rack to disengage. The first spring pushes open the second housing, removes the magnetic unlocking device, inserts the can, and pushes the second housing to move. The locking pin and locking rack continuously engage until the first and second latching blocks are flush with the top edge of the can, thus securing it. To unlock, place the magnetic unlocking device at the top unlocking protrusion to attract the steel column upward, thereby causing the locking pin and locking rack to disengage. The first spring pushes open the second housing, allowing the can to be removed.
[0029] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
