Description

Technical Field

[0001] This utility model relates to anti-theft locks, and in particular to an anti-theft lock for a bottle. Background Technology

[0002] When anti-theft measures are implemented for bottles, especially cosmetic bottles and wine bottles, the conventional method is to insert the bottle into the cavity of the anti-theft lock and then lock the bottle and the lock together using the locking mechanism. At this time, the bottom of the bottle is pressed against the trigger end of the buzzer inside the anti-theft lock. When the bottle is illegally separated from the anti-theft lock, the bottle separates from the trigger end of the buzzer, causing the buzzer to sound an alarm.

[0003] However, some bottles have an indentation at the bottom instead of a flat surface. Even if the bottle is inserted into the cavity of the anti-theft lock, the anti-theft lock will not work properly because the indentation cannot press against the trigger end of the buzzer.

[0004] In summary, how to achieve a proper fit between the anti-theft lock and the bottle body with a groove at the bottom has become an urgent problem for researchers in this field. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to achieve an anti-theft lock and a bottle body with a groove at the bottom;

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model is an anti-theft lock for a bottle, comprising: a shell with an open top; a buzzer fixed at the bottom inside the shell; a trigger plate disposed above the buzzer, with a contact point protruding from its bottom to engage with the trigger end of the buzzer; a lifting plate disposed within the shell, with multiple hooks extending upward from its outer periphery; and a locking mechanism disposed within the shell, wherein when the lifting plate moves to its lower limit position, the locking mechanism restricts the upward movement of the lifting plate.

[0008] Furthermore, a guide block is provided radially outward on the outer peripheral wall of the lifting plate; a guide groove matching the guide block is vertically opened on the inner wall of the housing.

[0009] Furthermore, the locking mechanism includes: a fixing plate, which extends upward from the bottom of the housing; and a magnetic pin, which is horizontally mounted on the fixing plate. One end of the magnetic pin has a contact sleeve that abuts against the top of the guide block, and an elastic pin is provided between the contact sleeve and the fixing plate.

[0010] Furthermore, the housing includes a separable base and a sleeve; the sleeve is fitted onto the top of the base.

[0011] Furthermore, the inner wall of the sleeve is provided with a plurality of protruding ribs, and the inner wall of the ribs is provided with the guide groove from bottom to top.

[0012] Furthermore, the base extends upward and is provided with a guide sleeve, the inner diameter of which matches the outer diameter of the lifting plate, and the guide sleeve is vertically provided with an avoidance groove that matches the guide block.

[0013] The beneficial effects of this utility model are as follows: This utility model is an anti-theft lock for bottle bodies. Even if there is a groove at the bottom of the bottle body, the lifting plate and trigger plate in this anti-theft lock can still cooperate with the buzzer through the contact between the surfaces, so as to achieve the cooperation between the anti-theft lock and the bottle body.

[0021] 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, and therefore only show the components relevant to the present invention.

[0022] This embodiment is an anti-theft lock for a bottle. See [link / reference] Figure 1 , Figure 1 The bottle body 01 is not engaged with the anti-theft lock in the figure. The bottle body 01 is placed on the lifting plate 2, and the multiple hooks 21 are in a bent state. At this time, the lifting plate 21 is in the upper limit position.

[0023] See Figure 2 , Figure 2This is a cross-sectional view of the bottle body 01 without the anti-theft lock engaging. The shell 1 has its opening facing upwards. The shell 1 consists of a sleeve 12 and a base 11 connected vertically. A guide sleeve 13 extends upwards from the bottom of the base 11. The guide sleeve 13 guides the lifting plate 2 into itself. (See also...) Figure 5 A vertical clearance groove 14 is provided on the guide sleeve 13. The function of the clearance groove 14 is to prevent interference between the guide block 22 and the guide sleeve 13 when the lifting plate 2 enters the guide sleeve 13. A buzzer 3 is provided inside the guide sleeve 13, and a trigger plate 31 is provided above the buzzer 3. The bottom of the trigger plate 31 is provided with a contact 32 that cooperates with the trigger end of the buzzer 3. See also Figure 5 A fixing plate 15 is provided on the outer side of the guide sleeve 13. A magnetic pin 4 is provided horizontally on the fixing plate 16. A contact sleeve 41 is located on the left side of the magnetic pin 4. A spring is provided between the contact sleeve 41 and the fixing plate 15. A strong magnet can approach the right end of the magnetic pin 4, so that the magnetic pin 4 moves to the right under the action of magnetic force.

[0024] See Figure 6 The inner wall of the sleeve 12 has multiple vertical ribs 121 protruding inward. When the lifting plate 2 moves downward, the ribs 121 can transform the bent hook 21 into a vertical hook 21. The inner wall of the ribs 121 has a guide groove 122. The guide block 22 on the lifting plate 2 cooperates with the guide groove 122. In this way, the lifting plate 2 will not deflect during the descent due to the cooperation between the guide block 22 and the guide groove 122. The bottom of the guide groove 122 is connected and the top is not connected. This allows the guide block 22 to move downward into the clearance groove 15 and restricts the upward movement of the guide block 22 without disengaging from the ribs 121.

[0025] See Figure 3 , Figure 3 The bottle body 01 is in the state of being engaged with the anti-theft lock. In the figure, the bottle body 01 is placed on the lifting plate 2. The lifting plate 2 moves downward to the lower limit state. Multiple hooks 21 are in a vertical state and are all located inside the housing 1. At this time, the hooks 21 are fastened to the protrusions on the surface of the bottle body 01, restricting the separation of the bottle body 01 from the anti-theft lock.

[0026] See Figure 4 , Figure 4 The figure shows a cross-sectional view of the bottle body 01 and the anti-theft lock. The lifting plate 2 is lowered to the lower limit position. The lifting plate 2 presses down the trigger plate 31, so that the contact point 32 presses down the trigger end of the buzzer 3, so that the buzzer 3 does not sound. At the same time, the guide 22 of the lifting plate 2 enters into the relief groove 14. At this time, the contact sleeve 41 at the left end of the magnetic pin 4 abuts against the upper surface of the guide 22, thus restricting the upward movement of the lifting plate 2.

[0027] When the anti-theft lock is forcibly broken, the lifting plate 2 separates from the trigger plate 31, and the buzzer 3 sounds an alarm. Only by placing a strong magnet to the right of the magnetic pin 4 and outside the base 11 can the lifting plate 2 be separated from the locking mechanism and the base 11.

[0028] In summary, even though the bottom of the bottle 01 has a groove, the contact between the lifting plate 2 and the trigger plate 31 in this anti-theft lock can still achieve cooperation with the buzzer 3, thus enabling the anti-theft lock to cooperate with the bottle 01.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, 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.
