Description

Technical Field

[0001] This utility model relates to the field of freezer technology, and in particular to a freezer light box structure. Background Technology

[0002] A refrigerated display case lightbox is a device used to display frozen or refrigerated products. It is commonly used in supermarkets, convenience stores, and the catering industry. Refrigerated display cases combine the preservation function of a refrigerated display case with the advertising display function of a lightbox. It can attract customers' attention while keeping food fresh. Refrigerated display cases are an effective tool for businesses to display and sell refrigerated products, increasing product exposure and promoting sales.

[0003] The existing light boxes installed on many freezers are mostly fixed directly to the freezer. This method results in a relatively high freezer, making it more prone to collisions during transportation or installation. Furthermore, the height of the freezer makes it very inconvenient to replace or maintain the image on the light box, thus reducing the ease of use of the device. Therefore, these problems need to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a refrigerator lightbox structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A refrigerator lightbox structure includes a refrigerator body, a top plate fixedly connected to the top of the refrigerator body, the top plate being horizontally positioned, a connecting frame rotatably connected to the top of the top plate, and support blocks fixedly connected to both ends of the top of the top plate. The connecting frame is rotatably connected between the two support blocks. A rotating mechanism for rotating the connecting frame is provided inside the top plate. One side of the connecting frame surface is open, and a lightbox is slidably connected inside the connecting frame. A display image is mounted on the surface of the lightbox. A sliding mechanism for sliding the lightbox is provided inside the connecting frame. By rotating the connecting frame, the connecting frame and lightbox on the top of the refrigerator body can be placed horizontally when not in use or when the device is moved. It also facilitates adjustment of the angle of the connecting frame and lightbox during use, thereby improving the usability of the device. Furthermore, the lightbox can be slid to facilitate changing the display image on its surface.

[0007] Preferably, the rotating mechanism includes a support rod, and fixed shafts are fixedly connected to both ends of the connecting frame surface. The two fixed shafts are rotatably sleeved inside two support blocks. The support rod is hinged to the side of the connecting frame surface away from the light box. A sliding groove is opened inside the top plate. A lead screw is rotatably connected inside the support block. The lead screw is horizontally set and passes through the sliding groove. A slider is horizontally slidably connected inside the sliding groove. The bottom end of the support rod is hinged to the top of the slider. The lead screw is rotatably sleeved inside the slider. The slider and the lead screw cooperate with each other. A first knob is rotatably connected to one side of the support block surface. The first knob is fixedly connected to one end of the lead screw and is used to restrict the horizontal sliding of the slider. With the support of the support rod, the connecting frame can be flipped, thereby facilitating the adjustment of the angle of the connecting frame.

[0008] Furthermore, the sliding mechanism includes a turntable, two handles are fixedly connected to the bottom of the lightbox, two fixed posts are fixedly connected to both sides of the symmetrical surface of the lightbox, two turntables are provided, and the two turntables are rotatably connected to opposite sides inside the connecting frame, a rotating shaft is rotatably connected inside the connecting frame, the two ends of the rotating shaft are respectively rotatably sleeved on the two ends of the connecting frame, the two turntables are sleeved on the surface of the rotating shaft, and both ends of the rotating shaft are provided with threads, a first pull rod is fixedly connected to the center of the surface of the two turntables, the two first pull rods are sleeved on the surface of the rotating shaft, the top ends of the two first pull rods are respectively rotatably sleeved on the surface of two of the fixed posts, a second pull rod is rotatably connected to the surface of the two turntables, the top ends of the two second pull rods are rotatably sleeved on the surface of the other two fixed posts, and a second knob is rotatably connected to both sides of the symmetrical surface of the connecting frame, the two second knobs are respectively rotatably sleeved on the two ends of the rotating shaft, and the two second knobs are respectively engaged with two threads to restrict the sliding of the lightbox, so that the lightbox can slide out of the connecting frame, thereby facilitating the maintenance of the lightbox.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. Turning the first knob will drive the lead screw to rotate, causing the slider to slide horizontally inside the groove. With the support rod connected, the angle of the connecting frame can be adjusted, thereby improving the effectiveness of the device. At the same time, the connecting frame can be rotated to a horizontal position, making it easier to move the device.

[0011] 2. Manually pull either of the two handles to rotate the two first and two second levers, which will cause the lightbox to slide out from inside the connecting frame. This makes it easy to maintain the lightbox and also facilitates the smoothing of the display screen. After completion, the lightbox can be pushed back into the connecting frame, thus improving the convenience of the device. Attached Figure Description

The bottom end of the support rod 22 is hinged to the top of the slider 42. The lead screw 4 is rotatably sleeved inside the slider 42. The slider 42 and the lead screw 4 cooperate with each other. A first knob 41 is rotatably connected to one side of the surface of the support block 12. The first knob 41 is fixedly connected to one end of the lead screw 4 to restrict the horizontal sliding of the slider 42. With the support of the support rod 22, the connecting frame 2 can be flipped, thereby facilitating the adjustment of the angle of the connecting frame 2.

[0020] In this utility model, the sliding mechanism includes a turntable 62. Two handles 33 are fixedly connected to the bottom of the light box 3. Two fixed posts 32 are fixedly connected to both symmetrical sides of the surface of the light box 3. Two turntables 62 are provided, rotatably connected to opposite sides inside the connecting frame 2. A rotating shaft 6 is rotatably connected inside the connecting frame 2, with both ends of the rotating shaft 6 rotatably fitted onto both ends of the connecting frame 2.

[0021] Working Principle: In actual use, rotating the connecting frame 2 allows for horizontal placement of the connecting frame 2 and light box 3 on the top of the freezer body 1 when not in use or when the device is moved. It also facilitates angle adjustment of the connecting frame 2 and light box 3 during use, thereby improving the device's performance. The light box 3 can also be slid to easily change the display image 31 on its surface. When in use, manually rotating the first knob 41 will rotate the lead screw 4, causing the slider 42 to slide horizontally within the slide groove 13. With the support rod 22 connected, the angle of the connecting frame 2 can be adjusted, further improving the device's performance. The connecting frame 2 can also be rotated to a horizontal position. The device is designed for easy handling. When the display screen 31 on the surface of the lightbox 3 needs to be replaced, the two second knobs 5 can be turned first to loosen the connection between the shaft 6 and the connecting frame 2. Then, either of the two handles 33 can be manually pulled, which will cause the two first pull rods 63 and the two second pull rods 64 to rotate, making the lightbox 3 slide out of the connecting frame 2. This facilitates the maintenance of the lightbox 3 and the replacement of the display screen 31. After completion, the lightbox 3 can be pushed back into the connecting frame 2, and the two second knobs 5 can be turned to restrict the two ends of the shaft 6, preventing the lightbox 3 from sliding down automatically, thus improving the convenience of the device.
