Description

Technical Field

[0001] This utility model relates to the technical field of refrigerator accessories, and in particular to a refrigerator top light pre-embedded box installation structure. Background Technology

[0002] As an indispensable refrigeration appliance in modern households, the functionality, durability, and ease of maintenance of the refrigerator's internal lighting system directly impact the user experience. The overhead light, as the core lighting unit inside the refrigerator, is typically integrated into the top of the cabinet using a pre-embedded box.

[0003] Traditional refrigerator ceiling light pre-embedded boxes mostly adopt an integrated design or screw fixing method, which has obvious limitations: on the one hand, the installation process of the pre-embedded light box is cumbersome, requiring tools to fix it layer by layer, which restricts assembly efficiency; on the other hand, when the internal circuit board fails, the entire pre-embedded box often needs to be disassembled, which is complicated and can easily damage components. In addition, existing snap-fit ​​structures mostly rely on rigid fastening, which is prone to loosening due to material fatigue after long-term use, leading to a decrease in the stability of the light body. To address these issues, we propose a new installation structure for refrigerator ceiling light pre-embedded boxes. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a refrigerator top light pre-embedded box installation structure.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a refrigerator ceiling light pre-embedded box installation structure, including a first pre-embedded box. Partitions are fixedly installed at both ends of the interior of the first pre-embedded box, dividing the interior of the first pre-embedded box into two snap-fit ​​cavities. A second pre-embedded box is movably installed inside the first pre-embedded box. Tensioning plates are fixedly installed at both ends of the second pre-embedded box, and the two tensioning plates are respectively snap-fitted into the snap-fit ​​cavities at both ends of the first pre-embedded box. Extending edges are fixedly installed at the far ends of the two tensioning plates. The bottom surface of the first pre-embedded box and the two extending edges... At the corresponding positions at the ends, there are fixed blocks for the extruded extension edges. The upper half of the outer wall of both fixed blocks is provided with slots. The main control board is fixedly installed inside the second embedded box. A detachable lamp board is movably connected to the bottom surface of the main control board. Connecting wires are fixedly connected to the outer walls of the main control board and the lamp board, and the ends of the two connecting wires are detachably connected. A detachable transparent cover is also movably installed at the lower end of the first embedded box. Fixed and movable blocks are connected to the two ends of the transparent cover, and the ends of the fixed and movable blocks are fixedly installed with protrusions that engage with the slots.

[0006] Preferably, connecting blocks are fixedly installed at both ends of the transparent cover, one of which is fixedly connected to the fixed block and the other is slidably connected to the movable block.

[0007] Preferably, the outer wall of the end of the movable block is provided with multiple sliding grooves, a pressure plate is slidably installed inside the sliding groove, a pull rod is fixedly installed at the center of the pressure plate, a fixing ring is fixedly installed at the end of the sliding groove, a spring is fixedly connected inside the sliding groove between the pressure plate and the fixing ring, the pull rod is located inside the spring, and the end of the pull rod passes through the fixing ring and extends to the outside of the sliding groove and is fixedly connected to the outer wall of the connecting block.

[0008] Preferably, side sealing plates are fixedly installed on both sides of the transparent cover, and the two side walls of the movable block are slidably connected to the side sealing plates.

[0009] Preferably, a limiting pin is slidably installed on the fixing block at a position corresponding to the end of the extension edge, and the limiting pin is located below the extension edge.

[0010] Preferably, the outer wall of the fixing block near the extension edge and the outer wall at the end of the extension edge are both inclined, and the inclination angles are the same.

[0011] Preferably, sealing strips are fixedly connected to both sides of the bottom surface of the first embedded box, and the sealing strips are located at the upper end of the side sealing plate. Beneficial effects

[0012] This utility model provides a pre-embedded box installation structure for a refrigerator ceiling light. It has the following beneficial effects:

[0013] (1) The refrigerator top light embedded box installation structure is based on the split design of the first embedded box and the second embedded box. It combines the elastic snap-fit ​​of the V-shaped section of the tension plate and the snap-fit ​​cavity, and the inclined guide surface of the extension edge and the fixing block to realize the quick alignment and self-locking of the second embedded box. During installation, it is only necessary to press the second embedded box to make the tension plate elastically deform in the snap-fit ​​cavity, and block the extension edge through the limit pin to complete the initial fixation. Then, the fixed and movable blocks at both ends of the transparent cover plate are linked, and the distance between the fixed and movable blocks is adjusted by the deformation of the spring so that the protrusion is accurately embedded in the slot. At the same time, the fixed and movable blocks can block the end of the limit pin to ensure the blocking effect of the limit pin on the extension edge. This structure simplifies the installation steps and effectively prevents loosening caused by vibration through mechanical interlocking by multi-level elastic cooperation and guide design.

[0014] (2) The refrigerator ceiling light pre-embedded box installation structure uses a detachable wire connection between the main control board and the light board. Combined with the split lampshade structure with a transparent cover, it significantly reduces the complexity of maintenance. When maintenance is required, it is only necessary to pull the fixed block outward to compress the spring and release the connection between the movable block and the fixed block, so that the transparent cover can be quickly removed. Then, the second pre-embedded box can be directly pulled out from the first pre-embedded box, and the main control board can be replaced separately after the connecting wires are separated. This avoids the disadvantage of the traditional structure requiring overall removal and simplifies the efficiency of maintenance and replacement of the integrated structure of the refrigerator ceiling light.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-7 As shown, a refrigerator ceiling light pre-embedded box installation structure includes a first pre-embedded box 1. A partition 12 is fixedly installed at both ends of the interior of the first pre-embedded box 1, dividing the interior of the first pre-embedded box 1 into two snap-fit ​​cavities. A second pre-embedded box 8 is movably installed inside the first pre-embedded box 1. Tensioning plates 11 are fixedly installed at both ends of the second pre-embedded box 8, and the two tensioning plates 11 are respectively snap-fitted into the snap-fit ​​cavities at both ends of the first pre-embedded box 1. Extension edges 13 are fixedly installed at the ends of the two tensioning plates 11 that are far apart from each other. Extrusion extensions are fixedly installed at corresponding positions on the bottom surface of the first pre-embedded box 1 and at the ends of the two extension edges 13. The upper half of the outer wall of the two fixed blocks 9 at the end of the edge 13 is provided with slots 10. The main control board 14 is fixedly installed inside the second embedded box 8. The bottom surface of the main control board 14 is movably connected to a detachable lamp board 15. The outer walls of the main control board 14 and the lamp board 15 are fixedly connected with connecting wires 16, and the ends of the two connecting wires 16 are detachably connected. The lower end of the first embedded box 1 is also movably installed with a detachable transparent cover plate 2. The two ends of the transparent cover plate 2 are respectively connected with fixed blocks 4 and movable blocks 6, and the ends of fixed blocks 4 and movable blocks 6 are fixedly installed with protrusions 22 that engage with the slots 10.

[0027] The first embedded box 1 is fixed inside the refrigerator with screws, thus embedding the first embedded box 1 in the top of the refrigerator. Next, the tension plates 11 installed at both ends of the second embedded box 8 are pressed, causing the two tension plates 11 to respectively engage with the engagement cavities separated by partitions 12 at both ends of the first embedded box 1. The tension plates 11 have a V-shaped cross-section. By engaging the tension plates 11 inside the engagement cavities, the second embedded box 8 can be quickly installed inside the first embedded box 1. As the two tension plates 11 move into the engagement cavities, the ends of the extended edges 13 on the outer sides of the tension plates 11 contact the outer wall of the fixing block 9. After the clamping plate 11 is fully engaged inside the locking cavity, the user engages the protrusion 22 located at the end of the movable locking block 6 into the slot 10 opened on one of the fixed blocks 9. Then, the user pulls the fixed locking block 4 outward to engage the protrusion 22 located at the end of the fixed locking block 4 into the slot 10 opened on the other fixed block 9. The above structures work together to achieve quick assembly of the refrigerator top light. If there is a problem with the main control board 14 or the light board 15, the user can quickly remove the transparent cover 2 or the second embedded box 8 to repair or replace the main control board 14 or the light board 15.

[0028] like Figure 2 As shown, connecting blocks 3 are fixedly installed at both ends of the transparent cover plate 2. One connecting block 3 is fixedly connected to the fixed card block 4, and the other is slidably connected to the movable card block 6. By pulling the fixed card block 4 outward, the end of the transparent cover plate 2 can be separated from the movable card block 6, thereby increasing the distance between the fixed card block 4 and the movable card block 6, making it easier for the user to engage the protrusions 22 at the ends of the fixed card block 4 and the movable card block 6 into the slots 10 opened on the two fixed blocks 9.

[0029] like Figure 6 As shown, the outer wall of the end of the movable block 6 is provided with multiple sliding grooves 17. A pressure plate 18 is slidably installed inside the sliding groove 17. A pull rod 19 is fixedly installed at the center of the pressure plate 18. A fixing ring 21 is fixedly installed at the end of the sliding groove 17. A spring 20 is fixedly connected inside the sliding groove 17 between the pressure plate 18 and the fixing ring 21. The pull rod 19 is located inside the spring 20, and the end of the pull rod 19 extends through the fixing ring 21 to the outside of the sliding groove 17 and is fixedly connected to the outer wall of the connecting block 3. When the pull rod 19 moves outward from the sliding groove 17, the pressure plate 18 at the end of the pull rod 19 squeezes the spring 20, causing the spring 20 to compress. The pull rod 19 then slides outward, which increases the distance between the fixed block 4 and the movable block 6, making it easier to insert the protrusions 22 at the ends of the fixed block 4 and the movable block 6 into the slots 10 opened on the two fixed blocks 9 respectively.

[0030] like Figure 4As shown, side sealing plates 5 are fixedly installed on both sides of the transparent cover plate 2, and the two side walls of the movable block 6 are slidably connected to the side sealing plates 5; the side sealing plates 5 can block the space between the fixed block 4 and the movable block 6 on both sides. The transparent cover plate 2, the connecting block 3, the fixed block 4, the side sealing plates 5 and the movable block 6 together form a lampshade that is easy for users to install and disassemble.

[0031] like Figure 7 As shown, a limiting pin 23 is slidably installed on the fixing block 9 at the position corresponding to the end of the extension edge 13, and the limiting pin 23 is located below the extension edge 13; when the second embedded box 8 is installed inside the first embedded box 1, the end of the extension edge 13 can be blocked by the limiting pin 23 to prevent the second embedded box 8 from falling out of the first embedded box 1.

[0032] like Figure 7 As shown, the outer wall of the fixing block 9 near the extension edge 13 and the outer wall of the end of the extension edge 13 are both inclined, and the inclination angles are the same; the inclined outer wall of the fixing block 9 can guide the end of the extension edge 13 when the second embedded box 8 is installed into the first embedded box 1.

[0033] like Figure 1 As shown, sealing strips 7 are fixedly connected to both sides of the bottom surface of the first embedded box 1, and the sealing strips 7 are located at the upper end of the side sealing plate 5. The sealing strips 7 are elastic and can fill the gap between the side sealing plate 5 and the first embedded box 1, maintaining the airtightness of the lampshade composed of the transparent cover plate 2, connecting block 3, fixing block 4, side sealing plate 5 and movable block 6.

[0034] The working principle of this utility model is as follows: In use, the first embedded box 1 is fixed inside the refrigerator with screws, thus embedding the first embedded box 1 at the top of the refrigerator. Then, the tension plates 11 installed at both ends of the second embedded box 8 are pressed, causing the two tension plates 11 to respectively engage with the engagement cavities at the ends of the first embedded box 1, separated by partitions 12. The tension plates 11 have a V-shaped cross-section. When the tension plates 11 are engaged inside the engagement cavities, the second embedded box 8 can be quickly installed inside the first embedded box 1. The two tension plates 11 move into the engagement cavities... During the movement of the part, the end of the extension edge 13 on the outer side of the tensioning plate 11 contacts the outer wall of the fixing block 9. After the tensioning plate 11 is completely locked inside the locking cavity, the user pushes the limiting pin 23 connected to the fixing block 9 to slide it below the extension edge 13. The limiting pin 23 can then block the end of the extension edge 13, so that the tensioning plate 11 and the second embedded box 8 are stably locked and installed inside the first embedded box 1. Then, the user holds the outer wall of the side sealing plate 5 corresponding to the fixing block 4, so that the protrusion at the end of the movable block 6... Block 22 is inserted into the slot 10 on one of the fixed blocks 9. Then, the user pulls the fixed block 4 outward. A pull rod 19 is provided between the movable block 6 and one of the connecting blocks 3. When the fixed block 4 is pulled outward, the pulling force applied by the user is transmitted to the pull rod 19, which is fixedly connected to the connecting block 3. The pull rod 19 then slides outward inside the slide groove 17. The pressure plate 18 fixed at the end of the pull rod 19 compresses the spring 20. Therefore, when the fixed block 4 is pulled outward, the distance between the fixed block 4 and the movable block 6 increases, and the user... The protrusion 22 at the end of the fixed block 4 can be engaged with the slot 10 opened on another fixed block 9. At this time, the position of the pressure plate 18 is reset under the action of the spring 20, and the connecting block 3 and the outer wall of the movable block 6 can be re-fitted. When the fixed block 4 and the movable block 6 are respectively engaged on the two fixed blocks 9, the ends of the two limit pins 23 can be blocked at the same time, so that the two limit pins 23 always keep blocking the extension edge 13, ensuring the stability of the second embedded box 8 installed inside the first embedded box 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
