[0001] This invention relates to the field of display rack technology, and specifically to a product display rack with anti-theft function. Background Technology

[0002] Display racks are shelves specifically designed for displaying product samples, products, or other items that require display. They come in various styles and are used in various industries. Utilizing venues such as museums and commercial product exhibitions, businesses participate in exhibitions primarily to showcase their products and corporate image. When businesses or other companies and organizations participate in exhibitions, they rent exhibition booths and use display racks or shelves to promote and showcase their products.

[0003] The primary purpose of current product display racks is to provide a place to display products. Some products have the ability to enhance the display effect. To facilitate viewing, they often use transparent materials or are directly exposed. Anti-theft functions are mostly alarm functions, which are difficult to provide substantial protection for the products. For some high-value products, damage and loss are significant losses. Summary of the Invention

[0004] The purpose of this invention is to address the current issues that product display racks primarily serve to provide a place to display products. Some products are designed to enhance the display effect, and for ease of viewing, they often use transparent materials or are directly exposed. Anti-theft functions are mostly alarm functions, which are insufficient to provide substantial protection for the products. For some high-value products, damage or loss would be a significant loss.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A product display rack with anti-theft function includes a display cabinet, which is fixedly installed on the upper surface of an anti-theft structure. An opening on the upper side of the anti-theft structure is hinged to an opening-and-closing base plate. A protective structure is laid on the upper surface of the opening-and-closing base plate. A product tray is movably installed below the opening-and-closing base plate. A lifting structure is movably connected to the bottom side of the product tray. The product tray includes a tray body. A connecting slot is opened at the lower edge of the rear surface of the movable upright plate. A connecting block is engaged in the connecting slot. The connecting block is fixedly installed at one end of an arc-shaped rack. The teeth of the arc-shaped rack mesh with a gear. A second torsion spring shaft is fixedly connected to one side of the gear. A magnetic column is fixedly installed on the side surface of the second torsion spring shaft. One end of the magnetic column is connected to a second electromagnet.

[0007] Furthermore, the display case includes a cabinet frame, a glass cover is snapped onto the front surface of the cabinet frame, a folding rod is hinged to the top inside the cabinet frame, an external rotor motor is embedded in each hinge bend of the folding rod, a scanning camera is embedded in the bottom of one end of the folding rod, and a display screen is embedded in the rear surface inside the cabinet frame.

[0008] Furthermore, the protective structure includes a cotton pad, with magnetic mounting bases fixedly installed at the four corners of the cotton pad. A first magnetic sheet is fixedly installed on the upper surface of the magnetic mounting base, and a second magnetic sheet is attached to the upper surface of the first magnetic sheet. A pull wire is fixedly connected to the upper surface of the second magnetic sheet.

[0009] Furthermore, the opening and closing base plate includes a base plate body, a torsion spring shaft is inserted and installed on one side of the base plate body, a roller is rotatably embedded on the upper surface of the base plate body, there are two base plate bodies, and a slot is opened on one side of the connection between the two sets of base plate bodies, and a metal pin is slidably installed on the other side. A magnetic sheet is embedded in the slot, and a first electromagnet is movably connected to one side of the metal pin. A capacitor is connected to one side of the first electromagnet.

[0010] Furthermore, the anti-theft structure includes an outer chamber, a hidden chamber is fixedly installed on the rear surface of the outer chamber, a locking pin movable groove is provided above the hidden chamber, a vertical plate movable groove is provided in the vertical direction of the locking pin movable groove, a bottom plate locking pin is slidably installed in the locking pin movable groove, and a return spring is fixedly connected to the rear side of the bottom plate locking pin.

[0011] Furthermore, a support is fixedly installed on the upper surface of the pallet body, a No. 1 motor is embedded inside the support, a turntable is fixedly installed at the output end of the No. 1 motor, and a movable upright plate is fixedly installed on the rear surface of the pallet body.

[0012] Furthermore, a capacitor is fixedly installed on the rear surface of the second electromagnet, and one side of the gear is fixedly connected to the output end of the second motor.

[0013] Furthermore, the lifting structure includes a lifting support frame, with lifting sliders fixedly installed at both ends of the front surface of the lifting support frame. A lead screw is inserted into the lifting slider, and the lower end of the lead screw is fixedly connected to the output end of motor No. 3. A coil spring is fixedly connected to the lower end of the output shaft of motor No. 3.

[0014] Furthermore, the cabinet frame is fixedly installed on the upper surface of the outer chamber, the bottom plate body is hinged to the upper opening of the outer chamber, the upper surface of the outer chamber is covered with a cotton pad, one end of the pull line is fixedly connected to the four corners of the upper surface of the outer chamber, the tray body is movably installed on the upper surface of the lifting support frame, and the lifting support frame is movably installed inside the outer chamber.

[0015] The beneficial effects of this invention are:

[0016] 1. When the pallet body falls into the bottom of the outer chamber, the weight of the pallet body, the movable upright plate, and the product itself causes the connecting slot and the connecting block to engage with each other. At the same time, the second electromagnet is de-energized and loses its magnetic force, releasing the restriction on the magnetic column. The second torsion spring shaft rotates back to its original position, driving the second gear and rotating the arc-shaped rack, causing the pallet body and the movable upright plate to flip over, storing the product inside the chamber for theft prevention and preservation. The external chamber confuses thieves, providing a false target location for theft, delaying time, and giving security personnel time to arrive.

[0017] 2. The folding rod drives the scanning camera to scan and record the appearance of the products inside the cabinet. When the product is taken out for other uses or is hidden indoors and cannot be retrieved in time, the product appearance information is displayed on the screen, temporarily replacing the physical product for display. The support base provides support to the bottom of the main body when the product is normally displayed, and the No. 1 motor and turntable contact the product, giving the product a certain rotation ability, which assists in scanning and recording appearance information and displaying it from all angles.

[0018] 3. After the two sets of base plates return to their original positions using the No. 1 torsion spring shaft, the electromagnetic force of the No. 1 electromagnet disappears, and the metal pin is attracted by the magnetic plate and gets into the slot, locking the two sets of base plates and sealing the outer chamber opening for the first layer of anti-theft. When the tray body slides out of the vertical plate movable groove, it releases the restriction on one end of the base plate locking pin. The base plate locking pin protrudes from the locking pin movable groove, and one end gets into the bottom side of the connecting seam between the two base plates, further locking the base plate body and providing support.

[0019] 4. When the product falls into the outdoor room, pull the cotton pad and it will fall together. At the same time, the pull string will pull the No. 1 and No. 2 magnetic pieces at the four corners of the cotton pad together and make them stick together, so that the cotton pad forms a bag-like structure to wrap and protect the product, providing a certain degree of anti-scratch and anti-collision effect. As the product and cotton pad fall, the connection between the No. 1 and No. 2 magnetic pieces will be broken by the inertia of falling. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-10As shown, a product display rack with anti-theft function includes a display case 1, which is fixedly installed on the upper surface of an anti-theft structure 4. A hinged bottom plate 3 is hinged to the upper opening of the anti-theft structure 4. A protective structure 2 is laid on the upper surface of the hinged bottom plate 3. A product tray 5 is movably installed below the hinged bottom plate 3. A lifting structure 6 is movably connected to the bottom of the product tray 5. The product tray 5 includes a tray body 501. A connecting slot 506 is opened at the lower edge of the rear surface of the movable upright plate 505. A connecting block 507 is engaged in the connecting slot 506. The connecting block 507 is fixedly installed at one end of an arc-shaped toothed rack 508. The teeth of the arc-shaped toothed rack 508 are aligned with the teeth of the rack. The wheels 509 mesh with each other, and a second torsion spring shaft 510 is fixedly connected to one side of the gear 509. A magnetic column 511 is fixedly installed on the side surface of the second torsion spring shaft 510. One end of the magnetic column 511 is connected to a second electromagnet 512. In use, the product is displayed and stored through the display case 1. In the event of theft by means of violence or power outage, the product, supported by the pallet body 501, passes over the opening and closing bottom plate 3 and is wrapped by the protective structure 2 and falls into the outer chamber 401. When the pallet body 501 falls into the bottom of the outer chamber 401, the weight of the pallet body 501, the movable upright plate 505, and the product itself causes the connecting slot 506 and the connecting card to... Blocks 507 interlock, and simultaneously, the second electromagnet 512 loses power and its magnetic force, releasing the restriction on the magnetic column 511. The second torsion spring shaft 510 rotates back to its original position, driving the second gear 509 and rotating the arc-shaped rack 508, causing the pallet body 501 and the movable upright plate 505 to flip, storing the product in the hidden chamber 402 for theft prevention and storage. The external chamber 401 confuses thieves, providing a false target location and delaying the arrival of security personnel. A capacitor 307 is fixedly installed on the rear surface of the second electromagnet 512, and one side of the gear 509 is fixedly connected to the output end of the second motor 513. The capacitor 307 delays the power-off time of the second electromagnet 512. When the product is taken out from the hidden chamber 402, the second motor 513 rotates the gear 509 in the opposite direction, forcing the pallet body 501 and the movable upright plate 505 to rotate back to their original positions. The cabinet frame 101 is fixedly installed on the upper surface of the outer chamber 401. The bottom plate body 301 is hinged to the upper opening of the outer chamber 401. The upper surface of the outer chamber 401 is covered with a cotton pad 201. One end of the pull line 205 is fixedly connected to the four corners of the upper surface of the outer chamber 401. The pallet body 501 is movably installed on the upper surface of the lifting support 601. The lifting support 601 is movably installed inside the outer chamber 401.

[0034] Display case 1 includes a frame 101, with a glass cover 102 snapped onto the front surface of the frame 101. A hinged lever 103 is hinged to the top inside the frame 101, with an external rotor motor 104 embedded in each hinge bend of the lever 103. A scanning camera 105 is embedded in the bottom of one end of the lever 103. A display screen 106 is embedded in the rear surface inside the frame 101. The lever 103 can drive the scanning camera 105 to scan and record the appearance of the products inside the frame 101. When the product is removed for other uses, or when the product is stored in the hidden compartment 402 and cannot be retrieved immediately, the display screen 106 displays the product's appearance information, temporarily replacing the physical product for display. A support 502 is fixedly installed on the upper surface of the tray body 501, with a primary motor 503 embedded inside the support 502. A turntable 504 is fixedly installed at the output end of the primary motor 503. A movable upright plate 505 is fixedly installed on the rear surface of the tray body 501. When the product is on display, seat 502 provides support to the bottom of the base plate 301 and is connected to the product by motor 503 and turntable 504, giving the product a certain rotational ability and assisting in scanning and recording appearance information and displaying it from all angles. The lifting structure 6 includes a lifting support frame 601, with lifting sliders 602 fixedly installed at both ends of the front surface of the lifting support frame 601. A lead screw 603 is inserted into the lifting slider 602. The lower end of the lead screw 603 is fixedly connected to the output end of motor 604. A coil spring 605 is fixedly connected to the lower end of the output shaft of motor 604. Motor 604 rotates the lead screw 603 to provide upward support to the lifting support frame 601 through the lifting slider 602, supporting the tray body 501 and thus providing support for the product and the base plate 301. At the same time, it accumulates potential energy for the coil spring 605. When motor 604 is de-energized, the coil spring 605 rotates the lead screw in the opposite direction to lower the lifting support frame 601, releasing the support for the tray body 501.

[0035] The opening and closing base plate 3 includes a base plate body 301. A torsion spring shaft 302 is inserted and installed on one side of the base plate body 301. A roller 303 is rotatably embedded in the upper surface of the base plate body 301. There are two base plate bodies 301, and a slot 304 is opened on one side of the connection between the two sets of base plate bodies 301. A metal pin 305 is slidably installed on the other side. A magnetic sheet is embedded in the slot 304. A first electromagnet 306 is movably connected to one side of the metal pin 305. A capacitor 307 is connected to one side of the first electromagnet 306. After the base plate body 301 loses the support of the support 502, it unfolds downward under the pressure of the product's own weight to avoid obstructing the product from falling. At the same time, through the surface of the base plate body 301... The roller 303 reduces the friction between the product and the base plate 301 when it slips. A capacitor temporarily supplies a certain amount of power to the electromagnet 306 to prevent the metal pins 305 from getting stuck in the slots 304 when the power is off. After the two sets of base plates 301 return to their original positions using the torsion spring shaft 302, the electromagnetic force of the electromagnet 306 disappears, and the metal pins 305, attracted by the magnetic sheet, get stuck in the slots 304, locking the two sets of base plates 301 and sealing the opening of the outer chamber 401, providing the first layer of anti-theft protection. The anti-theft structure 4 includes the outer chamber 401, and a hidden chamber 402 is fixedly installed on the rear surface of the outer chamber 401. When installing the entire equipment, the hidden chamber 402 is embedded in the wall of the exhibition hall. The concealed chamber 402 is completely concealed to further improve its protective performance. A locking pin groove 403 is provided above the concealed chamber 402, and a vertical plate groove 404 is provided vertically within the locking pin groove 403. A base plate locking pin 405 is slidably installed within the locking pin groove 403. A return spring 406 is fixedly connected to the rear side of the base plate locking pin 405. When the support plate body 501 slides out of the vertical plate groove 404, the restriction on one end of the base plate locking pin 405 is released. The base plate locking pin 405 protrudes from the locking pin groove 403, and one end engages with the bottom side of the joint between the two base plate bodies 301, further locking the base plate body 301 and providing support. The protective structure 2 includes a cotton pad 201, with the cotton pad 201 fixed at its four corners. The device is equipped with a magnetic mounting base 202. A first magnetic sheet 203 is fixedly installed on the upper surface of the magnetic mounting base 202. A second magnetic sheet 204 is attached to the upper surface of the first magnetic sheet 203. A pull cord 205 is fixedly connected to the upper surface of the second magnetic sheet 204. When the product falls into the outer chamber 401, it pulls the cotton pad 201 and falls together. At the same time, the pull cord 205 pulls the first magnetic sheet 203 and the second magnetic sheet 204 at the four corners of the cotton pad 201 to gather together and attract them, so that the cotton pad 201 forms a bag-like structure to wrap and protect the product, providing a certain degree of anti-scratch and anti-collision effect. At the same time, as the product and the cotton pad 201 fall, the connection between the first magnetic sheet 203 and the second magnetic sheet 204 is broken by the inertia of falling.

[0036] Working principle: In use, products are displayed and stored through display case 1. In the event of theft by means of force or power outage, the product, supported by the pallet body 501, passes over the opening and closing bottom plate 3 and is wrapped by the protective structure 2, falling into the outer chamber 401. When the pallet body 501 falls into the bottom of the outer chamber 401, the weight of the pallet body 501, the movable upright plate 505, and the product itself causes the connecting slot 506 and the connecting block 507 to engage with each other. At the same time, the second electromagnet 512 loses power and loses its magnetic force, releasing the restriction on the magnetic column 511. The second torsion spring shaft 510 rotates back to its original position, driving the second gear 509 to rotate and rotate the arc-shaped rack 508, causing the pallet body 501 and the movable upright plate 505 to flip over, putting the product into the hidden chamber 402. Inside, the product is stored securely to prevent theft. An external compartment 401 misleads thieves, providing a false target location and delaying the arrival of security personnel. A folding rod 103 drives a scanning camera 105 to scan and record the product's appearance inside the cabinet 101. When the product is removed for other uses or stored in a hidden compartment 402 and cannot be retrieved immediately, the display screen 106 shows the product's appearance information, temporarily replacing the physical product for display. A support 502 provides support to the bottom of the base 301 when the product is normally displayed, and a motor 503 and a turntable 504 contact the product, giving it a certain degree of rotational ability, assisting in the scanning and recording of appearance information and omnidirectional display. Motor 604 rotates the lead screw 603, which provides upward support to the lifting support frame 601 via the lifting slider 602, supporting the pallet body 501 and thus supporting the product and the base plate body 301. Simultaneously, it stores potential energy in the coil spring 605. When motor 604 is de-energized, the coil spring 605 reverses the rotation of the lead screw, causing the lifting support frame 601 to descend and release support for the pallet body 501. After losing support from the support frame 502, the base plate body 301 unfolds downwards under the weight of the product, preventing it from obstructing the product's fall. At the same time, the rollers 303 on the surface of the base plate body 301 reduce friction between the product and the base plate body 301 during slippage. A capacitor temporarily supplies a certain amount of electrical energy to the electromagnet 306 to prevent further damage during power outages. When the metal pin 305 engages with the slot 304, and the two sets of base plate bodies 301 return to their original positions using the first torsion spring shaft 302, the first electromagnet 306 loses its electromagnetic force, and the metal pin 305, attracted by the magnetic plate, engages with the slot 304, locking the two sets of base plate bodies 301 and sealing the opening of the outer chamber 401, providing the first layer of anti-theft protection. When the tray body 501 slides out from the vertical plate movable groove 404, it releases the restriction on one end of the base plate locking pin 405. The base plate locking pin 405 protrudes from the locking pin movable groove 403, and one end engages with the bottom side of the connecting seam between the two base plate bodies 301, further locking the base plate bodies 301 and providing support. When the product falls into the outer chamber 401, it pulls the cotton pad 201, causing it to fall as well.Simultaneously, the pull cord 205 pulls the first magnetic piece 203 and the second magnetic piece 204 at the four corners of the cotton pad 201, causing them to gather and adhere together, forming a bag-like structure that wraps and protects the product, providing some scratch and impact resistance. As the product and cotton pad 201 fall, the inertia of the fall breaks the connection between the first magnetic piece 203 and the second magnetic piece 204.
