Description

Technical Field

[0001] This invention relates to the field of commodity display equipment technology, specifically to an injection-molded layered display rack. Background Technology

[0002] In modern commerce, display racks serve as a crucial medium for product display and information presentation, and are widely used in various retail locations. Through display racks, businesses can arrange goods in an orderly manner and clearly present key information such as product name, price, specifications, and features using signage, thereby helping consumers quickly understand the products, enhancing the shopping experience, and promoting sales.

[0003] However, current display racks mostly use traditional methods of fixing signs by pasting or hanging. This method suffers from insecure fixing; after prolonged use, signs easily detach due to environmental factors and minor impacts during daily use, resulting in incomplete display of product information, interfering with consumers' shopping experience. More seriously, detached signs may fall from a height, injuring passersby and posing a significant safety hazard. Furthermore, the structure of traditional hanging display racks has limitations; their stability is difficult to guarantee under external impact or slight shaking, making them prone to falling, affecting product display, and potentially damaging goods, causing economic losses for businesses. Therefore, those skilled in the art have provided an injection-molded layered display rack to solve the problems mentioned in the background. Summary of the Invention

[0004] 1. Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an injection-molded layered display rack, which solves the problems of unstable signage and easy detachment of the display rack.

[0005] 2. Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A molded multilayer display rack includes a shelf and a hanging plate. The shelf has a label slot on its outer side, and two limiting blocks are fixedly connected to the inner side of the label slot. A label body is placed inside the label slot. An operating cavity is formed on the outer side of the shelf, and a linkage component is provided on the inner side of the shelf. The linkage component includes a sleeve rotatably connected to the inner side of the shelf, with one end of the sleeve located inside the operating cavity. A rotating shaft is inserted into the inner side of the sleeve, and a slot is formed on the outer side of the rotating shaft. A cross-shaped insert is fixedly connected to one end of the rotating shaft, and a first gear is fixedly connected to the outer side of the rotating shaft. A conversion component and a limiting component are provided on the inner side of the shelf. A locking component is provided on the inner side of the label body. Multiple equidistant hanging slots are formed on the outer side of the hanging plate. Two Z-shaped hanging plates are fixedly connected to the upper side of the shelf, with the outer sides of the Z-shaped hanging plates hooked onto the inner sides of the hanging slots. A cover plate is slidably connected to the inner side of the operating cavity. Through the above technical solution, by setting the sign slot and the inner limiting block, the main body of the sign can be initially fixed. Then, through the combined design of the limiting block, linkage component and locking component, the main body of the sign can be pressed, realizing the secure installation of the main body of the sign, effectively preventing the sign from falling off due to environmental factors or collisions, ensuring the complete display of product information, and eliminating the safety hazard of the sign falling and injuring consumers. Afterwards, the Z-shaped hanging plate on the shelf can realize the quick installation of the shelf on the hanging plate. At the same time, under the action of the conversion component, the linkage component and the limiting component are connected, thereby quickly limiting the shelf and preventing the shelf from falling due to external force. This also enhances the stability of the display rack and prevents the shelf from falling and injuring consumers, further improving the safety of the shelf display rack.

[0006] Furthermore, two guide grooves are provided on the upper side of the shelf, and a push plate is slidably connected to the inner side of the two guide grooves. Two symmetrical springs are fixedly connected to one side of the push plate, and the other end of the springs is fixedly connected to the inner side of the guide groove. A baffle is fixedly connected to the upper side of the shelf. The above technical solution, through the structure consisting of guide grooves, push plates, springs and baffles, can push the goods during the placement or retrieval process, thereby making it easier for customers to pick up the goods and improving the customer experience.

[0007] Furthermore, two symmetrical sliding grooves are provided on the outer side of the rotating shaft, and two fixing blocks are fixedly connected to the inner side of the sleeve, with the outer side of the fixing blocks slidably connected to the inner side of the sliding grooves. Through the above technical solution, the sliding groove on the outer side of the rotating shaft and the fixed block on the inner side of the sleeve cooperate with each other, so that the rotating shaft can both rotate and move axially within the sleeve, providing a flexible motion basis for the linkage component to realize multiple function conversions, and ensuring the smoothness and stability of power transmission between components.

[0008] Furthermore, a first rotating handle is fixedly connected to one end of the sleeve, and anti-slip texture is provided on the outer side of the first rotating handle; The above technical solution, through the anti-slip texture design of the first rotating handle and its outer side, makes it convenient for operators to manually rotate the sleeve, thereby driving the linkage component to work. The operation is simple and convenient, improving the efficiency of fixing and disassembling signs during the use of the display rack, as well as the efficiency of limiting and adjusting the middle shelf of the display rack.

[0009] Furthermore, the conversion assembly includes a first mounting base fixedly connected to the inner side of the shelf, a first lead screw rotatably connected to the inner side of the first mounting base, and one end of the first lead screw located inside the operating cavity. A second rotating handle is fixedly connected to one end of the first lead screw, and anti-slip texture is provided on the outer side of the second rotating handle. Through the above technical solution, by setting up a structure consisting of a first mounting base, a first lead screw, and a second rotating handle, the operator can drive the first lead screw to rotate by rotating the second rotating handle, thereby moving the moving block, controlling the working state of the linkage components, realizing the switching between different functions, and improving the flexibility of the display rack.

[0010] Furthermore, a movable block is threadedly connected to the outer side of the first lead screw, and the outer side of the movable block is rotatably connected to the inner side of the slot. Through the above technical solution, the threaded connection design between the first lead screw and the moving block can convert the rotation of the first lead screw into the linear movement of the moving block, accurately control the axial position of the rotating shaft, ensure the precise and reliable cooperation between the linkage component and other components, and enhance the stability of the overall structure of the display rack.

[0011] Furthermore, the locking assembly includes a second mounting base fixedly connected to the inner side of the shelf, a second lead screw rotatably connected to the inner side of the second mounting base, a second gear fixedly connected to one end of the second lead screw, the second gear meshing with the first gear, and a movable frame threadedly connected to the other end of the second lead screw; Through the above technical solution, the second mounting base, the second lead screw, the second gear and the moving frame cooperate with each other. When the first gear drives the second gear to rotate, the second lead screw rotates and drives the moving frame to move, thereby further locking the main body of the sign and ensuring that the sign is firmly fixed and not easy to fall off.

[0012] Furthermore, two pressure rods are fixedly connected to one side of the movable frame. The position of the pressure rods is adapted to the position of the limiting block. The inner sides of the two pressure rods are inserted into the inner side of the shelf, and one end of the pressure rod extends through the inner side of the shelf to the inside of the nameplate groove. By using the above technical solution, and by setting the pressure bar on one side of the movable frame to match the position of the limiting block, when the locking component is working, the pressure bar can press the main body of the sign tightly into the sign slot from both sides. Compared with the traditional fixing method, this greatly improves the fixing strength of the sign and prevents the sign from loosening or falling off.

[0013] Furthermore, the limiting assembly includes a first rotating rod and a second rotating rod. One end of the first rotating rod is rotatably connected to the inner side of the shelf, and the outer side of the second rotating rod is rotatably connected to the inner wall of the first rotating rod. Synchronous pulleys are fixedly connected to the outer sides of both the first and second rotating rods. A synchronous belt is provided on the outer sides of the two synchronous pulleys, and the two synchronous pulleys are connected via the synchronous belt. Two limiting blocks are fixedly connected to the outer side of the second rotating rod. A cross slot is provided at one end of the first rotating rod. The inner wall shape of the cross slot matches the outer shape of the cross block. The outer side of the cross block is inserted into the inner side of the cross slot. A fixing iron ring is fixedly connected to the outer side of the first rotating rod. Two magnets are provided on the outer side of the first rotating rod. The central axes of the two magnets are perpendicular to each other, and the magnets and the fixing iron ring are magnetically connected. Through the above technical solution, by setting up a transmission structure consisting of a first rotating rod, a second rotating rod, a synchronous pulley, and a synchronous belt, the rotation of the rotating shaft can be transmitted to the second rotating rod, thereby driving the limiting block to rotate. This achieves the limitation of the connection position between the shelf and the hanging plate, enhancing the overall structural stability of the display rack and preventing the shelf from falling accidentally. The cross slot on the first rotating rod is adapted to the cross plug at one end of the rotating shaft, ensuring the accuracy and stability of the power transmission between the linkage component and the limiting component. The magnetic connection design between the fixing iron ring on the outside of the first rotating rod and the magnet block can fix the first rotating rod after the limiting component is in place, preventing it from rotating accidentally due to external force, further enhancing the stability of the display rack structure.

[0014] Furthermore, both the shelf and the main body of the sign are made of acrylic injection molding, and the surface of the shelf is screen-printed using a screen printing process. Through the above technical solution, the shelves and signage are made of acrylic injection molding material and treated with screen printing, which makes the display rack look beautiful, has good wear resistance and corrosion resistance, and extends the service life of the display rack. At the same time, the screen printing treatment can clearly display product information and improve the display effect.

This invention provides an injection-molded shelf display rack. By setting a label slot and cooperating with an inner limiting block, the label body can be initially fixed. Then, through the combined design of the limiting block, linkage component, and locking component, the label body can be pressed tightly, achieving a firm installation of the label body. This effectively prevents the label from falling off due to environmental factors or collisions, ensuring the complete display of product information and eliminating the safety hazard of the label falling and injuring consumers. Subsequently, the Z-shaped hanging plate on the shelf allows the shelf to be quickly installed on the hanging plate. At the same time, the linkage component and the limiting component are connected under the action of the conversion component, thereby quickly limiting the shelf and preventing the shelf from falling due to external force. This also enhances the stability of the display rack, prevents the shelf from falling and injuring consumers, and further improves the safety of the shelf display rack.

Through the cooperative design of the sleeve and the rotating shaft, it achieves the dual functions of rotation and axial movement, laying the foundation for multiple function conversions of the display rack. The first gear meshes with the locking component to securely lock the main body of the sign. At the same time, the cross-shaped insert at the end of the rotating shaft can drive the limiting component to work, enhancing the structural stability of the display rack. In addition, the conversion component can adjust the position of the rotating shaft by controlling the moving block, flexibly switching the working state of the linkage component. Compared with the prior art, the linkage component significantly improves the convenience of operation and the versatility of functions of the display rack.

By setting up the structure of the first mounting base 701, the first lead screw 702 and the second rotating handle 704, the operator can drive the first lead screw 702 to rotate by rotating the second rotating handle 704, thereby realizing movement. The movement of block 703 controls the working state of linkage component 6, enabling the switching between different functions and improving the flexibility of the display rack. The outer side of the first lead screw 702 is threadedly connected to the moving block 703, and the outer side of the moving block 703 is rotatably connected to the inner side of the slot 603.

[0023] A limiting component 9 is provided on the outer side of the shelf 1. Under the action of the aforementioned conversion component 7, the linkage component 6 is connected to the limiting component 9, thereby quickly limiting the shelf 1 to prevent it from falling due to external force. This also enhances the stability of the display rack, preventing the shelf 1 from falling and injuring consumers, and further improving the safety of the shelf display rack. The limiting component 9 includes a first rotating rod 901 and a second rotating rod 902. One end of the first rotating rod 901 is rotatably connected to the inner side of the shelf 1, and the outer side of the second rotating rod 902 is rotatably connected to the inner wall of the first rotating rod 901. The outer sides of both the first rotating rod 901 and the second rotating rod 902 are fixed. The first rotating rod 901 is fixedly connected to the second rotating rod 902. The outer side of the two rotating rods 903 is provided with a synchronous belt 904. The two rotating rods 903 are connected by transmission through the synchronous belt 904. The outer side of the second rotating rod 902 is fixedly connected to two limiting blocks 906. By setting the transmission structure composed of the first rotating rod 901, the second rotating rod 902, the synchronous wheel 903 and the synchronous belt 904, the rotation of the rotating shaft 602 can be transmitted to the second rotating rod 902, thereby driving the limiting blocks 906 to rotate, realizing the limiting of the connection position between the shelf 1 and the hanging plate 10, enhancing the overall structural stability of the display rack, and preventing the shelf 1 from falling off accidentally.

[0024] One end of the first rotating rod 901 has a cross slot 905. The inner wall shape of the cross slot 905 matches the outer shape of the cross insert 604. The outer side of the cross insert 604 is inserted into the inner side of the cross slot 905.

[0025] A locking component 8 is provided on the inner side of the sign body 4. Through the combined design of the limiting block 3, the linkage component 6, and the locking component 8, the sign body 4 can be pressed firmly, achieving a secure installation of the sign body 4. This effectively prevents the sign from falling off due to environmental factors or collisions, ensuring the complete display of product information and eliminating the safety hazard of the sign falling and injuring consumers. The locking component 8 includes a second mounting base 801 fixedly connected to the inner side of the shelf 1. A second lead screw 802 is rotatably connected to the inner side of the second mounting base 801. A second gear 803 is fixedly connected to one end of the second lead screw 802, which meshes with a first gear 605. The other end of the second lead screw 802 is threadedly connected to a movable frame 804. Through the connection of the second mounting base 801, the second lead screw 802, the second gear 803, and the movable frame 804, the sign body 4 is securely installed. The first gear 605 drives the second gear 803 to rotate, which in turn causes the second lead screw 802 to rotate and drive the moving frame 804 to move, thereby further locking the main body 4 of the sign and ensuring that the sign is firmly fixed and not easy to fall off. Two pressure rods 805 are fixedly connected to one side of the moving frame 804. The position of the pressure rods 805 is adapted to the position of the limit block 3. The inner side of the two pressure rods 805 is inserted into the inner side of the shelf 1, and one end of the pressure rods 805 extends through the inner side of the shelf 1 to the inside of the sign slot 2. By setting the pressure rods 805 on one side of the moving frame 804 to be adapted to the position of the limit block 3, when the locking assembly 8 is working, the pressure rods 805 can press the main body 4 of the sign tightly into the sign slot 2 from both sides. Compared with the traditional fixing method, the fixing strength of the sign is greatly improved, preventing the sign from loosening or falling off.

[0026] The outer side of the mounting plate 10 has multiple equally spaced hanging slots 11. Two Z-shaped hanging plates 12 are fixedly connected to the upper side of the shelf 1, with the outer sides of the Z-shaped hanging plates 12 hooked onto the inner sides of the hanging slots 11. The Z-shaped hanging plates 12 on the shelf 1 allow for quick installation of the shelf 1 onto the mounting plate 10. A cover plate 17 is slidably connected to the inner side of the operating cavity 5. By setting the cover plate 17, the first rotating handle 608 and the second rotating handle 704 inside the operating cavity 5 can be covered, improving aesthetics and reducing the impact of external factors on the linkage component 6 and the conversion component 7. Two guide slots 13 are opened on the upper side of the shelf 1. A push plate 14 is slidably connected to the inner side of the two guide slots 13. Two symmetrical springs 15 are fixedly connected to one side of the push plate 14. The other end of the spring 15 is fixedly connected to the inner side of the guide groove 13, and a baffle 16 is fixedly connected to the upper side of the shelf 1. By setting the structure composed of the guide groove 13, the push plate 14, the spring 15 and the baffle 16, the product can be pushed during the placement or retrieval of the product, thereby making it easier for customers to pick up the product and improving the customer experience. The shelf 1 and the main body of the label 4 are both made of acrylic injection molding. The surface of the shelf 1 is screen-printed. The use of acrylic injection molding material and screen printing process for the shelf 1 and the main body of the label 4 makes the display rack look beautiful, has good wear resistance and corrosion resistance, and extends the service life of the display rack. At the same time, the screen printing process can clearly display product information and improve the display effect.

[0027] Working Principle: When using this display rack, the main body 4 of the label is placed into the label slot 2 of the shelf 1, initially positioned by the limiting block 3. Then, the first handle 608 at one end of the sleeve 601 is rotated, causing the sleeve 601 to drive the rotating shaft 602 to rotate. The first gear 605 on the rotating shaft 602 meshes with the second gear 803 in the locking assembly 8, driving the second lead screw 802 to rotate. This causes the moving frame 804 to move the pressure rod 805, firmly pressing the main body 4 into the label slot 2, thus securing the label. Then, the second handle 704 in the conversion assembly 7 is rotated, causing the first lead screw 702 to rotate and drive the moving block 703 to move, changing the axial position of the rotating shaft 602. This disengages the first gear 605 in the linkage assembly 6 from the second gear 803 in the locking assembly 8. The moving block 703 continues to move, causing the cross-shaped insert 6 at the end of the rotating shaft 602 to... After the first rotating rod 901 is inserted into the cross slot 905 at its end, when the rotating shaft 602 rotates, the cross insert 604 on it drives the first rotating rod 901 to rotate. Through the transmission of the synchronous pulley 903 and the synchronous belt 904, the second rotating rod 902 drives the limiting block 906 to rotate, causing the limiting block 906 to change from a horizontal to a vertical position, so that the second rotating rod 902 cannot be disengaged from the hanging slot 11. This limits the shelf 1 and enhances the stability of the display rack. Then, the position and magnetic connection design of the fixing iron ring 907 and the magnet block 908 ensure that the rotation of the limiting block 906 is always in two states: horizontal and vertical. After the limiting block 906 completes its limiting, the fixing iron ring 907 is vertical. At the same time, the attraction of the magnet block 908 fixes the first rotating rod 901, preventing it from rotating accidentally due to external forces, and further enhancing the stability of the display rack structure. Subsequently, the push plate 14 and spring 15 on the upper side of shelf 1 push the product during the product retrieval process, thereby making it easier for customers to retrieve the product and improving the customer experience.
