Description

Technical Field

[0001] This invention relates to the field of intelligent anti-theft display cabinet technology, specifically a display cabinet. Background Technology

[0002] Display cases are protective display stands used to showcase merchandise. They are found in many places, such as jewelry stores, cosmetics stores, and accessory stores, protecting the goods while providing customers with an excellent way to identify and select products.

[0003] Chinese patent application number CN202121703352.5 discloses an intelligent display cabinet with an alarm function, comprising a base and a cabinet body fixed to the upper side of the base. A display cabinet is mounted on the upper side of the cabinet body, an anti-theft panel is mounted on the top of the display cabinet, a display platform is mounted on the inner bottom side of the display cabinet, and an alarm device is mounted on the lower side of the display cabinet. The alarm device includes a balance block, a support plate, and a pressure sensor. The pressure sensor is positioned between the balance block and the support plate. A slide is mounted on the lower side of the support plate, and a lifting frame is mounted on the lower side of the slide. A telescopic rod is mounted on the inner bottom side of the cabinet body. In this technical solution, the pressure sensor detects changes in the display cabinet's weight or after an impact. The pressure sensor senses the pressure change and, through a controller, retracts the lifting frame via the telescopic rod, thereby retracting the display cabinet and protecting the goods. However, this technical solution does not consider the scenario where the glass breaks under a strong external impact before the lifting platform has fully descended, resulting in an unsatisfactory anti-theft effect. It also addresses the issue of the time difference between the speed of brute force and the operation of the lifting platform, and secondly, it does not allow for efficient replacement of displayed goods.

[0004] Therefore, we made improvements and proposed a display case. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] This invention discloses a display cabinet, comprising a cabinet body, a display case mounted on top of the cabinet body, a first anti-theft plate and a second anti-theft plate mounted on top of the display case, a display light mounted below the first anti-theft plate, and a keyhole on the second anti-theft plate. A first motor is housed inside the cabinet body, a lead screw is connected to the first motor, a slider is mounted on the lead screw, a bearing is mounted at the other end of the lead screw, a lifting plate is mounted above the bearing, a second motor is mounted on one side below the lifting plate, a rotating disk is connected to the second motor, a support plate and a return rod are mounted on the rotating disk, a wheel is mounted on one side of the rotating disk, a connecting plate is mounted below the wheel, a lock is connected to the other end of the connecting plate, a rotating plate is mounted above the wheel, a torsion spring is mounted on the rotating plate, and a retaining plate is connected to the rotating plate.

[0007] As a preferred embodiment of the present invention, the cabinet is layered, with an anti-theft cabinet door on the outer side, a latch on the anti-theft cabinet door, a combination lock door on the inner side of the anti-theft cabinet door, a keypad and fingerprint unlocking mechanism on the combination lock door, steel plates on both sides of the display cabinet, and bulletproof glass on the display cabinet.

[0008] As a preferred embodiment of the present invention, a guide rail is provided on the inner side of the first anti-theft plate, and sliding grooves are provided on both sides of the second anti-theft plate. The first and second anti-theft plates are slidably connected. A lock groove is provided at the top of the box, and the size of the lock groove is slightly larger than that of the second anti-theft plate.

[0009] As a preferred embodiment of the present invention, the retaining plate is provided with a slot and the retaining plate is configured to be hollow, and the connecting plate passes through the retaining plate.

[0010] In a preferred embodiment of the present invention, the wheel is connected to the connecting plate, and the rotating plate is rotatably connected to the wheel.

[0011] The beneficial effects of this invention are:

[0012] 1. This type of display case, by setting up an anti-theft panel, can quickly lower to protect the display case when it is damaged, allowing the exhibits to fall into the case. The second anti-theft panel will slide down via a guide rail, quickly and effectively protecting the display case. After the second anti-theft panel falls, the second motor starts to move, driving the rotating disk to rotate. The support plate touches the wheel, and the wheel drives the connecting plate to move forward. The lock on the connecting plate passes through the keyhole and locks the second anti-theft panel. At this time, the rotating plate on the wheel also moves forward under the drive of the wheel. The hook at the front end of the rotating plate hooks the groove on the fixing plate, so that the lock effectively locks the second anti-theft panel.

[0013] 2. This type of display case, with its descending platform, can transport exhibits into the case for protection, and also facilitates the replacement of exhibits. The first motor starts moving, driving the lead screw to rotate, which in turn drives the slider on the lead screw to move up and down, raising and lowering the lifting plate inside the display case, so that the exhibits can enter into the case or appear inside the display case.

[0022] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0023] Example: Figure 1-6As shown, the present invention discloses a display cabinet, comprising a cabinet body 1, a display cabinet 7 disposed on top of the cabinet body 1, a first anti-theft plate 5 and a second anti-theft plate 6 disposed on top of the display cabinet 7, a display light 51 disposed below the first anti-theft plate 5, a keyhole 61 provided on the second anti-theft plate 6, a first motor 8 disposed inside the cabinet body 1, a lead screw 9 connected to the first motor 8, a slider 10 disposed on the lead screw 9, a bearing 11 disposed at the other end of the lead screw 9, and a lifting mechanism disposed above the bearing 11. A lowering plate 71 is provided with a second motor 13 on one side below the lowering plate 71. A rotating disk 14 is connected to the second motor 13. A support plate 141 and a restoring rod 142 are provided on the rotating disk 14. A wheel 17 is provided on one side of the rotating disk 14. A connecting plate 18 is provided below the wheel 17. A lock head 19 is connected to the other end of the connecting plate 18. A rotating plate 16 is provided above the wheel 17. A torsion spring 20 is provided on the rotating plate 16. The rotating plate 16 is connected to a fixing plate 15.

[0024] The cabinet 1 is layered, with an anti-theft cabinet door 2 on the outer side and a latch 21 on the anti-theft cabinet door 2. The inner side of the anti-theft cabinet door 2 is a combination lock door 3, which is equipped with a keypad 4 and fingerprint unlocking. The display cabinet 7 is equipped with steel plates on both sides and bulletproof glass. The double doors can effectively prevent theft of the exhibits inside the display cabinet. By using different unlocking methods, it also increases the time and difficulty for thieves to unlock the cabinet, thus providing time for the police to arrive.

[0025] The first anti-theft plate 5 has a guide rail 52 on its inner side, and the second anti-theft plate 6 has sliding grooves 62 on both sides. The first anti-theft plate 5 and the second anti-theft plate 6 are slidably connected. The top of the box body 1 has a lock groove 12. The size of the lock groove 12 is slightly larger than that of the second anti-theft plate 6. When the display case is forcibly dismantled, it can effectively protect the exhibits, increase the difficulty of forcibly dismantling, and provide sufficient time for the exhibits to enter the box body.

[0026] The fixing plate 15 is provided with a slot and is hollow. The connecting plate 18 passes through the fixing plate 15. The fixing plate 15 is equipped with a return spring, which does not affect the normal passage of the connecting plate 18. The return spring can also drive the connecting plate 18 to reset the rotating disk 14.

[0027] The wheel 17 is connected to the connecting plate 18, and the rotating plate 16 is rotatably connected to the wheel 17. The rotating plate 16 is the main part that provides locking support. Its connection and separation with the fixing plate 15 play a key role in locking.

[0028] Working Principle: When this type of display cabinet is in use, if someone forcibly removes the display cabinet 7, the second anti-theft plate 6 will slide downwards via the guide rail 52, quickly and effectively protecting the display cabinet 7. After the second anti-theft plate 6 falls, the second motor 13 starts to move, driving the rotating disk 14 to rotate. The support plate 141 touches the wheel 17, and the wheel 17 drives the connecting plate 18 to move forward. The lock head 19 on the connecting plate 18 passes through the keyhole 61 and locks the second anti-theft plate 6. At this time, the rotating plate 16 on the wheel 17 also moves forward under the drive of the wheel 17. The hook at the front end of the rotating plate 16 hooks the groove on the fixing plate 15, so that the lock head 19 effectively locks the second anti-theft plate 6. At the same time as the second anti-theft plate 6 falls, the first motor 8 starts to move. The movement of the motor drives the lead screw 9 to rotate, which in turn causes the slider 10 on the lead screw 9 to move up and down, retracting the lifting plate 71 inside the display case 7, allowing the exhibits to enter the case 1 for protection. When unlocking is required, the return rod 142 on the rotating disk 14 touches the tail of the rotating plate 16, causing the rotating plate 16 to rotate. This disengages the hook at the top of the rotating plate 16 from the fixing plate 15. The return spring inside the fixing plate 15 causes the rotating disk 14 to move back to its original position, thereby locking the second anti-theft plate 6 with the lock head 19. When changing exhibits, the combination door 3 is opened. At this time, the combination door 3 needs to be unlocked by pressing the keypad 4. Then, the first motor 8 rotates, causing the lifting plate 71 on the slider 10 to descend, thereby changing the exhibits.
