Description

Technical Field

[0001] This utility model relates to the field of anti-theft tag technology, specifically a hanger lock. Background Technology

[0002] In the retail industry, supermarkets typically use hooks to display merchandise to save space and improve display effectiveness. Common hook structures include horizontally arranged rods with an upward-sloping anti-drop bar at the end to prevent merchandise from slipping. To reduce the risk of theft, anti-theft locks are usually installed on the rods. These locks have a keyhole that fits onto the rod and is secured by a locking mechanism. When the lock is locked, the anti-drop bar prevents movement, thus preventing merchandise from being removed unnecessarily.

[0003] However, existing anti-theft locks have the following technical defects:

[0004] 1. The inner diameter of the lock hole of a burglarproof lock is usually larger than the diameter of the hanging rod, resulting in a large gap between the lock and the hanging rod, which makes it prone to shaking.

[0005] 2. When the anti-theft lock is moved to the connection between the hanging rod and the anti-drop rod, it can be easily removed by shaking or twisting it past the anti-drop rod, thus rendering the anti-theft function ineffective.

[0006] To address these issues, existing technologies typically involve replacing the hooks, i.e., increasing the diameter of the hook rod to match the keyhole of the anti-theft lock. However, this method has significant drawbacks: 1. Supermarkets need to completely replace their hook systems, which is costly for existing stores. 2. The replacement process requires removing merchandise, disrupting normal sales and reducing operational efficiency.

[0007] Therefore, there is an urgent need for an improved anti-theft lock structure that can effectively enhance anti-theft performance without replacing the hook, while reducing modification costs, to meet the actual needs of supermarkets. Utility Model Content

[0008] To address the technical problems in the background art, this utility model discloses a hanging bracket lock head.

[0009] This utility model provides a hanging rack lock head, including a first lock shell with a first semi-circular arc groove and a second lock shell with a second semi-circular arc groove; when the first lock shell and the second lock shell are spliced ​​and locked, the first semi-circular arc groove and the second semi-circular arc groove are spliced ​​to form a lock hole for engaging the hanging rod; a rubber pad is also provided between the first lock shell and the second lock shell.

[0010] When the first and second lock housings are locked, pressure is generated between the rubber pad and the hanging rod.

[0011] The beneficial effects of the above setup are: 1. The elastic properties of the rubber pad automatically generate contact pressure with the hanging rod when the lock shell is closed. This not only adapts to slight differences in the size of the hanging rod but also ensures that the lock head maintains a stable clamping state under different usage scenarios, enhancing reliability; 2. The synergistic effect of the lock hole formed by the splicing of the first and second lock shells and the rubber pad effectively eliminates the gap between the lock hole and the hanging rod, preventing the lock head from shaking; the friction generated by the rubber pad under pressure can greatly increase the fit between the lock head and the hanging rod, making the friction between the lock head and the hanging rod greater and the connection tighter, preventing the lock head from going over the anti-drop bar due to shaking or twisting, and significantly reducing the risk of theft of goods; 3. Only the rubber pad needs to be added to the original lock head and the lock shell structure optimized, resulting in low modification costs. Moreover, the installation process does not require the removal of goods or discontinuation of hooks, and will not affect the normal operation of the supermarket.

[0012] If the rubber pad's position is unstable, misalignment can easily occur during installation, causing it to fail to contact the hanging rod and lose its function. Therefore, a further improvement is made: a receiving cavity is provided inside the first lock housing to hold the rubber pad. The specific structure of the receiving cavity is as follows: a recessed first locking platform is provided on the side of the first lock housing connecting to the second lock housing; the first locking platform and the side wall connecting to its end constitute the receiving cavity. With this design, the receiving cavity serves to limit the installation of the rubber pad, ensuring stable contact between the rubber pad and the hanging rod when the lock is locked.

[0013] Since conventional hanging hooks come in two different diameter models, in order to improve the applicability of this utility model and reduce costs, a further design is made: there are two locking holes, namely a first locking hole and a second locking hole; the diameter of the first locking hole is smaller than the diameter of the second locking hole.

[0014] If a rubber pad is provided for both the first and second keyholes, the installation will become more complicated. Therefore, a further improvement is to extend the rubber pad to both the first and second keyholes.

[0015] If the first locking platform extends to the second locking hole, the first locking hole may become too tight or too loose. If the first locking hole is too tight, it will cause excessive resistance when splicing the first and second lock housings, making assembly difficult. If the first locking hole is too loose, the rubber pad will lose its function. Based on this, a further improvement is made as follows: a second locking platform is connected to one side of the first locking platform; the depth of the first locking platform is less than the depth of the second locking platform; the first locking platform corresponds to the first locking hole; and the second locking platform corresponds to the second locking hole.

[0016] If the rubber pad is flat, the lock needs to be bent to match the first and second locking platforms when locking, which can easily cause the rubber pad to break. Based on this, a further improvement is made: the rubber pad is composed of a first connecting part, a transition part and a second connecting part connected in sequence; the first connecting part fits into the first locking platform; the second connecting part fits into the second locking platform.

[0017] If the first and second lock housings are set as independent entities, they are easily lost. Based on this, a further improvement is made: the first and second lock housings are hinged at one end and snapped together at the other end.

[0018] The specific structure of the first and second lock housings engaging is as follows: the first lock housing is provided with a protruding bolt; the second lock housing is provided with a groove for engaging the bolt; the bolt is provided with an engaging hole; the opening and closing end of the second lock housing is also provided with a lock cylinder that is elastically connected by a spring, can be attracted by a magnet, and engages with the engaging hole.

[0026] 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.

[0027] like Figure 1 and Figure 2The present invention discloses a hanging rack lock head, including a first lock shell 1 with a first semi-circular arc groove 101 and a second lock shell 2 with a second semi-circular arc groove 21. When the first lock shell 1 and the second lock shell 2 are engaged and locked, the first semi-circular arc groove 101 and the second semi-circular arc groove 21 are joined to form a locking hole for engaging the hanging rod. In this embodiment, there are two locking holes, one large and one small, namely a first locking hole 6 and a second locking hole 7, with the diameter of the first locking hole 6 being smaller than the diameter of the second locking hole 7. This arrangement is used to match two commonly used specifications of hooks in supermarkets: hooks with larger diameters match the second locking hole 7, and hooks with smaller diameters match the first locking hole 6.

[0028] The first lock housing 1 and the second lock housing 2 are hinged at one end via a hinge shaft, and snapped together at the other end. This design ensures that the first lock housing 1 and the second lock housing 2 are always connected and are not easily lost. The specific snap-fit ​​structure of the first lock housing 1 and the second lock housing 2 is as follows: the first lock housing 1 is provided with a protruding latch 9, and the latch 9 is provided with a snap-fit ​​hole 11. The second lock housing 2 is provided with a snap-fit ​​groove 10 for engaging the latch 9.

[0029] The specific locking structure of the first lock shell 1 and the second lock shell 2 is as follows: Figure 2 , Figure 4 and Figure 5 As shown, the opening and closing end of the second lock housing 2 is provided with an integrally formed sleeve 22. The lower end of the sleeve 22 is open, and the upper end is provided with a snap-fit ​​plate 23. The snap-fit ​​plate 23 is provided with an insertion hole 15 communicating with the slot 10. An upward-facing mounting sleeve 14 is inserted into the sleeve 22 and fixed by welding. The upper end of the mounting sleeve 14 abuts against the snap-fit ​​plate 23, and the lower end is flush with the lower end of the sleeve 22. A spring 12 and a lock cylinder 13 that can be attracted by a magnet are installed inside the mounting sleeve 14. The lock cylinder 13 protrudes radially in the middle, thus forming two shoulders. The lower end of the spring 12 abuts against the bottom of the mounting sleeve 14, and the upper end fits the lock cylinder 13 to the lower shoulder, thus achieving an elastic connection of the lock cylinder 13. Under the elastic force of the spring 12, the upper shoulder of the lock cylinder 13 abuts against the snap-fit ​​plate 23, so that the upper end of the lock cylinder 13 passes through the insertion hole 15 and is inserted into the snap-fit ​​hole 11. This locks the first lock housing 1 and the second lock housing 2. When the magnet comes into contact with the lower end of the mounting sleeve 14, the lock cylinder 13 is magnetically attracted and moves downward, disengaging from the locking hole 11, thus unlocking the first lock housing 1 and the second lock housing 2.

[0030] On one side of the first lock housing 1 connecting to the second lock housing 2, there are recessed and interconnected first locking platform 4 and second locking platform 8. The first locking platform 4 is directly opposite the first lock hole 6, and the second locking platform 8 is directly opposite the second lock hole 7, with the depth of the first locking platform 4 being less than the depth of the second locking platform 8. The first locking platform 4, the second locking platform 8, and their peripheral sidewalls 5 form a receiving cavity, in which a rubber pad 3 is engaged. One end of the rubber pad 3 extends to the first locking platform 4, and the other end extends to the second locking platform 8. The receiving cavity is designed to limit the installation of the rubber pad 3, ensuring that when the lock is locked, the rubber pad 3 can stably contact the hook and press the hook firmly.

[0031] Because the first card platform 4 and the second card platform 8 have a depth difference, therefore... Figure 2 and Figure 3 As shown, the rubber pad 3 is structured as follows: it consists of a first connecting part 31, a transition part 32, and a second connecting part 33 connected in sequence; the first connecting part 31 and the second connecting part 33 are parallel, and there is a gap between their end faces on the same side; the transition part 32 forms an obtuse angle with both the first connecting part 31 and the second connecting part 33. When the rubber pad 3 is installed, the first connecting part 31 fits against the first locking plate 4; the second connecting part 33 fits against the second locking plate 8. When the lock head is locked, the rubber pad 3 will only form a depression at the hook, without any other deformation. Therefore, the rubber pad 3 will not break when the lock head is locked. Furthermore, the thickness of the first connecting part 31 protruding from the first lock hole 6 and the thickness of the second connecting part 33 protruding from the second lock hole 7 can be kept consistent, ensuring that the pressure of the lock head on the hook remains consistent when the lock head engages hooks of different diameters.

[0032] Compared to existing technologies, the advantages of this embodiment are: 1. The elastic properties of the rubber pad 3 allow it to automatically generate contact pressure with the hanging rod when the lock shell is closed. This not only adapts to minor size differences in the hanging rod but also ensures that the lock head maintains a stable clamping state under different usage scenarios, enhancing reliability; 2. The synergistic effect of the lock hole formed by the splicing of the first and second lock shells 2 and the rubber pad 3 effectively eliminates the gap between the lock hole and the hanging rod, preventing the lock head from shaking; the friction generated by the rubber pad 3 under pressure can significantly increase the fit between the lock head and the hanging rod, resulting in greater friction and a tighter connection, preventing the lock head from crossing the anti-drop bar due to shaking or twisting, and significantly reducing the risk of merchandise theft; 3. Only the rubber pad 3 needs to be added to the original lock head and the lock shell structure optimized, resulting in low modification costs. Moreover, the installation process does not require removing merchandise or disabling the hooks, and will not affect the normal operation of the supermarket.

[0033] 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.
