Description

Technical Field

[0001] This utility model relates to the field of freezers, and in particular to a detachable light box for freezers. Background Technology

[0002] The LED lightbox advertising machine on top of a vertical freezer consists of a cabinet, built-in LED lights, an outer transparent acrylic panel, and an advertising cloth on the back of the acrylic panel. All components are integrated and connected to the freezer via a rigid structure, becoming an important display medium for product marketing in retail settings. In existing technologies, the advertising cloth is usually fixed to the lightbox using adhesive, screws, or embedded slots, and the acrylic panel is also fastened to the cabinet using bolts or clips, making it inconvenient to replace the advertising cloth.

[0003] When the products sold in the freezer change (such as switching from frozen drinks to dairy products, or from snacks to fresh produce), the advertising cloth needs to be replaced simultaneously to match the marketing needs. However, under the existing structure, replacing the advertising cloth requires first using tools to remove the fixing bolts of the acrylic plate or pry open the clips. Some advertising cloths that are glued on also need to be forcibly peeled off, which can easily cause scratches on the acrylic plate, deformation of the cabinet frame, and damage to the edges of the advertising cloth. In addition, the replacement process requires suspending the power supply to the light box, and the operation steps are cumbersome (usually requiring 1-2 people to cooperate and taking more than 15 minutes), which affects the normal operation of the freezer. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a detachable lightbox for refrigerators, offering a targeted solution for the "convenient replacement" of advertising cloth, effectively meeting the actual needs of retail terminals for high-frequency and high-efficiency replacement of advertising cloth.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please combine Figure 1-6 A detachable lightbox for a freezer comprises a rear frame 1 fixed to the top of the freezer and a front frame 2 connected to the rear frame 1. The upper part of the front frame 2 has an open structure with an opening, while the upper part of the rear frame has a protruding upper edge 4. After the rear frame 1 and the front frame 2 are joined together, a sealing gasket is placed on their contact surfaces to increase the sealing effect. At this time, the upper edge 4 fits into the opening at the upper part of the front frame 2, forming a complete lightbox structure. The two are fixed together by a locking component, as shown in the instruction manual. Figure 1 As shown.

[0022] The lightbox features an LED bead 7 fixedly mounted on the inner wall of the rear frame 1, a fixed acrylic plate 3 fixedly mounted on the front of the front frame 2, and a movable acrylic plate 6 mounted on the inner wall of the front frame 2. Adhesive (preferably commercially available double-sided tape) can be pre-installed at the corners of the movable acrylic plate 6 to adhere the advertising cloth to its outer surface. The position of the movable acrylic plate 6 is then adjusted using a limiting component to fit against the back of the fixed acrylic plate 3, thus squeezing the advertising cloth between the two sets of acrylic plates for fixation. By connecting an external power source and turning on the LED bead 7 on the inner wall of the rear frame 1, the back of the advertising cloth can be illuminated. Combined with the two sets of transparent acrylic plates, this enables advertising display.

[0023] It should be added that the inner wall of the rear frame 1 of the lightbox is connected to the inner wall of the front frame 2 of the lightbox by a movable telescopic rod 5. The movable telescopic rod 5 can be referred to as the handle of a normal umbrella. This common movable telescopic structure is fixedly connected to the inner wall of the rear frame 1 of the lightbox at one end and to the inner wall of the front frame 2 of the lightbox at the other end.

[0024] Therefore, when replacing the advertising cloth, by opening the locking assembly and pulling the front frame 2 of the lightbox outward to create distance between it and the rear frame 1, the movable telescopic rod 5 will not completely separate the two. After the distance is created, the opening at the top of the front frame 2 is fully exposed to the outside. Refer to the instruction manual attached in magnified mode. Figure 4 Appendix Figure 5 Staff can quickly replace the advertising cloth directly through the opening at the top of the front frame 2 of the lightbox. The whole process requires no tools, no effort or time, and no need to completely disassemble the front frame 2 of the lightbox or turn off the power. The operation is very convenient. After the replacement is completed, the front frame 2 of the lightbox can be pushed back and fixed to the rear frame 1 of the lightbox again using the locking component.

[0025] Here, in conjunction with the instruction manual appendix Figure 6 Furthermore, additional explanation is needed regarding the locking components. These components include a plug-in block 8 fixedly connected to the inner wall of the front frame 2 of the lightbox, and a plug-in seat 9 fixedly connected to the inner wall of the rear frame 1 of the lightbox. The plug-in block 8 is inserted into a corresponding slot on the outer side of the plug-in seat 9. A locking pin 901 is laterally inserted through the outer wall of the plug-in seat 9. After the plug-in block 8 is inserted into the slot of the plug-in seat 9, its outer wall also has a slot 902 that mates with the locking pin 901. An extension block 903 is fixedly connected to the outer end of the locking pin 901. A disassembly groove 10 is provided through the outer side of the light box rear seat 1. The outer end of the extension block 903 is slidably inserted into the disassembly groove 10. Magnetic suction pieces that attract each other are provided between the inner wall of the extension block 903 and the outer wall of the plug-in seat 9. The outer side of the extension block 903 is also provided with a groove, which makes it convenient for the staff to use their fingers to pry into the groove on the outer side of the extension block 903 from the disassembly groove 10 and stretch and adjust the extension block 903 to drive the locking pin 901 to move horizontally, thereby locking and separating the plug-in block 8 from the plug-in seat 9.

[0026] Based on this, it should be added that the side of the latch 901 near the plug block 8 adopts a smooth inclined surface structure design, which makes it convenient for the plug block 8 to be automatically pushed outward when it is plugged into the plug seat 9. After the two are plugged in, the latch 901 aligns with the slot 902 on the outside of the plug block 8. Under the magnetic attraction of the magnetic sheet on the outer wall of the plug seat 9 on the inside of the extension block 903, the latch 901 is driven to automatically return to its original position and lock into the slot 902, thus completing the automatic and quick locking of the plug block 8, which also completes the quick assembly between the back frame 1 and the front frame 2 of the light box.

[0027] Based on this, it should be added that the limiting component includes a connecting ear 601 fixedly connected to the outside of the movable acrylic plate 6, and a sliding groove 602 is provided on the inner wall of the plug block 8. The connecting ear 601 can slide back and forth within the sliding groove 602, and the connecting ear 601 is connected to the inner wall of the sliding groove 602 by a spring 603. In the default state, the spring 603 extends, causing the connecting ear 601 and the connected movable acrylic plate 6 to move away from the fixed acrylic plate 3. However, when the rear frame 1 and the front frame 2 of the lightbox are connected... During assembly, the connector 8 is inserted into the connector 9, and the outer side of the connector 9 is fixedly connected to the limit rod 604, which is connected to the outer side of the connecting ear 601. This pushes the connecting ear 601 to move and compress the spring 603. The connecting ear 601 drives the movable acrylic plate 6 to approach the fixed acrylic plate 3, and squeezes the advertising cloth between the two sets of acrylic plates to achieve fixation. There is no need to use glue to stick the advertising cloth over a large area, and it is also convenient to replace the advertising cloth later. There is no need to remove it by force, which increases the ease of operation during replacement.

[0028] Finally, it should be noted that the installation method for light box 1 and the freezer body can be found in the instruction manual. Figure 7 Since this is based on existing technology, only a brief description is provided here to help the examiner understand the installation steps and wiring connection methods. See the attached instruction manual. Figure 7 As shown, insert light box 1 into the hanging column at the top of the freezer body, push it back forcefully in the direction shown in the figure, and when you hear a "click", it means that it is installed in place. Then take out two screws to fix the back of light box 1 to achieve a fixed connection, and plug the freezer body wiring terminal into the corresponding light box terminal.
