Description
Technical Field
[0001] This utility model relates to the field of jewelry display case technology, specifically a jewelry display case with a self-locking anti-theft function. Background Technology
[0002] Jewelry display cases are cabinets used to showcase jewelry and ornaments. They are usually made of various materials such as glass, metal, and wood. They are beautiful in appearance, sturdy in structure, easy to assemble and disassemble, and convenient to transport. They are widely used in company showrooms, exhibitions, department stores, and other places, especially in the jewelry and ornaments industry. Because the jewelry in the display cases is of high value, traditional display cases are mostly protected by high-strength glass. However, the glass joints can break when subjected to external force, which can lead to the theft of jewelry. In order to prevent jewelry theft, a jewelry display case with a self-locking anti-theft function has been proposed.
[0003] For example, the jewelry display case with anti-theft function disclosed in the authorization announcement number CN218960412U includes an outer frame, a first anti-theft mechanism, a second anti-theft mechanism and a counterweight anti-theft mechanism. The first anti-theft mechanism is provided at the front of the outer frame, and the second anti-theft mechanism is provided inside the outer frame. The counterweight anti-theft mechanism is provided at the bottom of the inner part of the second anti-theft mechanism.
[0004] Although it achieves a reasonable structure, the display case is located above the outer frame in normal operation. When staff leave work, the front and side doors can be opened first, and then the first drive motor can be started. This allows the display case to be moved vertically through transmission components such as the transmission screw, sliding threaded sleeve, and load-bearing sliding plate, so that the display case can be stored inside the outer frame for protection. Then, the staff can press the control component to move the barrier steel plate horizontally to the side above the outer frame to block the reserved slots through which the display case can pass.
[0005] However, this does not solve the problem that existing jewelry display cases are not conducive to convenient linkage and closure for jewelry protection, nor to multi-level protection against theft and robbery, thus affecting the effectiveness of jewelry self-locking and anti-theft. Utility Model Content
[0006] The purpose of this utility model is to provide a jewelry display case with a self-locking anti-theft function, so as to solve the problem mentioned in the background art that jewelry display cases are not convenient for easy linkage and closure to protect jewelry, which is not conducive to multi-level protection against theft and robbery of jewelry, and affects the effectiveness of the self-locking anti-theft function of jewelry.
[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide a jewelry display case with a self-locking anti-theft function, comprising a display case body and an inner cylinder. The inner cylinder is disposed inside the display case body, and a support plate is installed at the top of the inner cylinder. A drive motor is installed inside the display case body on one side of the inner cylinder, and a gear is installed at the output end of the drive motor. Multiple sets of opening and closing plates with equal spacing are disposed inside the support plate. Limiting posts are installed at the top of each opening and closing plate, and pin holes are installed inside each opening and closing plate on one side of the limiting posts. A rotating gear ring is slidably mounted on the top of the support plate, and the rotating gear ring meshes with the gear. Multiple sets of arc-shaped grooves with equal spacing are installed inside the rotating gear ring, and the arc-shaped grooves are slidably connected to the limiting posts. A limiting ring is disposed on the inner wall of the rotating gear ring, and the rotating gear ring is slidably connected to the limiting ring. Multiple sets of bolts with equal spacing are disposed inside the limiting ring, and the bolts pass through the limiting ring and the pin holes and are fixedly connected to the support plate. The opening and closing plates are movably connected to the bolts through the pin holes.
[0008] Furthermore, four sets of integrated frames with equal spacing are installed on the inner wall of the inner cylinder, and each integrated frame has a lead screw movably installed inside.
[0009] Furthermore, each of the integrated frames is equipped with a servo motor at its bottom, and the output end of the servo motor is connected to the lead screw.
[0010] Furthermore, the surface of the lead screw is fitted with a threaded sleeve, and the threaded sleeve is threadedly connected to the lead screw.
[0011] Furthermore, a support frame is provided inside the inner cylinder, and the support frame is connected to the threaded sleeve.
[0012] Furthermore, a support base is installed at the top of the support frame, and multiple sets of equally spaced electric push rods are movably installed on the side wall of the support base, with push arms installed at the output ends of each electric push rod.
[0013] Furthermore, each of the support base sidewalls on one side of the electric push rod is provided with an opening and closing arm. Each opening and closing arm is provided with a movable shaft at the end near the support base, and the opening and closing arm is movably connected to the support base through the movable shaft. The push arm is movably connected to the opening and closing arm.
[0014] Furthermore, protective covers are installed on the inner walls of the opening and closing arms, and a display stand is installed on the top of the support base.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the jewelry display case not only realizes convenient linkage and closure to protect the jewelry, facilitating multi-level protection against theft and robbery of the jewelry, but also improves the self-locking and anti-theft effect of the jewelry.
[0016] Jewelry is displayed on a stand. When a theft alarm is triggered, an external controller activates an electric push rod, which moves a push arm. This push arm then rotates an opening / closing arm around a movable axis, causing the protective covers to rotate. This causes multiple sets of protective covers to close together, forming a closed protective shield that provides primary protection for the jewelry on the stand. A servo motor then drives a lead screw, which moves a threaded sleeve downwards. The threaded sleeve moves a support frame downwards, and the support frame moves the support base, the stand, and the jewelry into the inner cylinder for secondary protection. This system provides convenient, interconnected, and closed protection for the jewelry, facilitating multi-level theft prevention.
[0017] By turning on the drive motor, the drive motor drives the gear to rotate, which in turn drives the rotating gear ring to rotate. The rotating gear ring drives the limit post to rotate through the arc groove, and the limit post drives the opening and closing plate to rotate around the bolt as the axis. This causes multiple sets of opening and closing plates to rotate and close, thereby closing the display case body and protecting the inner cylinder. This provides a third level of protection for the jewelry, thus improving the self-locking and anti-theft effect of the jewelry. Attached Figure Description

[0033] Please see Figures 1 to 6This utility model provides an embodiment of a jewelry display case with a self-locking anti-theft function, comprising a display case body 1 and an inner cylinder 2. The inner cylinder 2 is disposed inside the display case body 1, and a support plate 11 is installed at the top of the inner cylinder 2. A drive motor 5 is installed inside the display case body 1 on one side of the inner cylinder 2, and the drive motor 5 provides power driving. A gear 6 is installed at the output end of the drive motor 5. Multiple sets of opening and closing plates 9 with equal spacing are disposed inside the support plate 11. A limit post 8 is installed at the top of each opening and closing plate 9, and a limit post 8 is installed inside each opening and closing plate 9 on one side of the limit post 8. A rotating gear ring 3 is slidably mounted on the top of the support plate 11, which is equipped with a pin hole 12. The rotating gear ring 3 meshes with the gear 6. Multiple sets of arc-shaped grooves 10 with equal spacing are installed inside the rotating gear ring 3. The arc-shaped grooves 10 are slidably connected to the limiting post 8. A limiting ring 4 is provided on the inner wall of the rotating gear ring 3. The rotating gear ring 3 is slidably connected to the limiting ring 4. Multiple sets of bolts 7 with equal spacing are provided inside the limiting ring 4. The bolts 7 pass through the limiting ring 4 and the pin hole 12 and are fixedly connected to the support plate 11. The opening and closing plate 9 is movably connected to the bolts 7 through the pin hole 12.
[0034] Jewelry is displayed on stand 14. When a theft alarm is received, an external controller activates an electric push rod 20, which moves a push arm 21. The push arm 21 then rotates an opening / closing arm 22 around a movable shaft 23, causing the protective cover 24 to rotate. This allows multiple protective covers 24 to close together, forming a closed protective shield to cover the jewelry, providing primary protection for the jewelry on stand 14. Simultaneously, a servo motor 16 is activated, driving a lead screw 15 to rotate. With the lead screw 15 threadedly connected to a threaded sleeve 17, the lead screw 15 moves the threaded sleeve 17 downwards, which in turn moves a support frame 18 downwards. The support frame 18 then moves the support base 19, stand 14, and jewelry into the inner cylinder 2, where the inner cylinder 2 provides secondary protection for the jewelry. This convenient, interconnected closed-loop protection system facilitates multi-level theft prevention for the jewelry.
[0035] Four sets of integrated frames 13 with equal spacing are installed on the inner wall of the inner cylinder 2. Each integrated frame 13 has a lead screw 15 movably installed inside it. Each integrated frame 13 has a servo motor 16 installed at its bottom. The servo motor 16 plays the role of power drive, and the output end of the servo motor 16 is connected to the lead screw 15.
[0036] The surface of the lead screw 15 is fitted with a threaded sleeve 17, and the threaded sleeve 17 is threadedly connected to the lead screw 15. The inner cylinder 2 is provided with a support frame 18, and the support frame 18 is connected to the threaded sleeve 17.
[0037] A support base 19 is installed at the top of the support frame 18. Multiple sets of electric push rods 20 with equal spacing are movably installed on the side wall of the support base 19. The electric push rods 20 play a power driving role, and each of the output ends of the electric push rods 20 is equipped with a push arm 21.
[0038] An opening and closing arm 22 is provided on the side wall of the support base 19 on one side of the electric push rod 20. The end of the opening and closing arm 22 near the support base 19 is provided with a movable shaft 23. The opening and closing arm 22 is movably connected to the support base 19 through the movable shaft 23. The push arm 21 is movably connected to the opening and closing arm 22.
[0039] The inner wall of the opening and closing arm 22 is equipped with a protective cover 24, and the top of the support base 19 is equipped with a display stand 14.
[0040] Turn on the drive motor 5, which drives the gear 6 to rotate. Under the mutual meshing of the gear 6 and the rotating gear ring 3, and the sliding engagement between the rotating gear ring 3 and the support plate 11, the gear 6 drives the rotating gear ring 3 to rotate. Under the sliding engagement between the limiting post 8 and the arc groove 10, the rotating gear ring 3 drives the limiting post 8 to rotate through the arc groove 10. The limiting post 8 drives the opening and closing plate 9 to rotate around the bolt 7 as the axis, thereby driving multiple sets of opening and closing plates 9 to rotate and close, thus closing the display case body 1 to protect the inner cylinder 2, thus providing a third level of protection for the jewelry, and improving the self-locking and anti-theft effect of the jewelry.
[0041] Working principle: Jewelry is displayed on display stand 14. When a theft alarm is received, an external controller activates the electric push rod 20, which moves the push arm 21. The push arm 21 then rotates the opening and closing arm 22 around the movable shaft 23, causing the protective cover 24 to rotate. This causes multiple sets of protective covers 24 to close together, forming a closed protective cover that protects the jewelry on display stand 14. This provides initial protection. The servo motor 16 then drives the lead screw 15 to rotate, which in turn moves the threaded sleeve 17 downwards. The threaded sleeve 17 moves the support frame 18 downwards, and the support frame 18 moves the support base 19, display stand 14, and jewelry into the inner cylinder 2. 2. To provide secondary protection for the jewelry, the drive motor 5 is then turned on, which drives the gear 6 to rotate. Under the mutual meshing of the gear 6 and the rotating gear ring 3, and the sliding engagement between the rotating gear ring 3 and the support plate 11, the gear 6 drives the rotating gear ring 3 to rotate. Under the sliding engagement between the limiting post 8 and the arc groove 10, the rotating gear ring 3 drives the limiting post 8 to rotate through the arc groove 10. The limiting post 8 drives the opening and closing plate 9 to rotate around the bolt 7 as the axis, thereby driving multiple sets of opening and closing plates 9 to rotate and close, thus closing the display case body 1 to protect the inner cylinder 2, thereby providing better protection for the jewelry and preventing it from being stolen. The above is the complete usage of the jewelry display case with self-locking anti-theft function.
[0042] 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 invention involved in the embodiments of this disclosure is not limited to 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-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
