Description

Technical Field

[0001] This utility model relates to the field of display case lighting technology, and in particular to a light guide plate mounting assembly suitable for display cases. Background Technology

[0002] As an important facility for commercial display, display cases typically require internal light guide plates and light source components to achieve uniform lighting effects on the display area. In existing technologies, light guide plates are mostly installed in the display case frame using simple slots or pressure plates, and the light source is generally an LED light strip, directly attached to the frame or the edge of the light guide plate. Although this structure can basically meet the lighting requirements, it still has shortcomings in terms of installation stability, heat dissipation performance, and subsequent maintenance.

[0003] Specifically, existing light guide plate mounting components have relatively simple fixing methods. During long-term use, the light guide plate is prone to loosening or displacement due to vibration or force, resulting in unstable coupling between the light guide plate and the light source, which affects the uniformity of the display case lighting and the display effect. At the same time, LED light sources generate a lot of heat during continuous operation. If the mounting frame does not have a reasonable heat conduction and heat dissipation structure, heat accumulation can easily shorten the life of the light source and may cause the internal temperature of the display case to rise. In addition, the structural design of existing light guide plate mounting components often lacks modularity, making the operation complicated and maintenance inefficient when the light guide plate needs to be replaced or cleaned. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a light guide plate mounting assembly suitable for display cases, so as to solve the problems of unstable fixation of light guide plates and insufficient heat dissipation of light sources in the prior art.

[0005] To achieve the above objectives, this utility model provides a light guide plate mounting assembly suitable for display cases, comprising: an aluminum frame;

[0006] A limiting component is installed on one side of the aluminum frame to fix the position of the light guide plate. The aluminum frame is provided with a mounting groove and a sliding hole through the mounting groove. A pressure plate is slidably installed on one side of the aluminum frame. Several sliding columns are fixed on the pressure plate. The end of each sliding column is provided with a pressing block. The pressing block is located in the mounting groove and contacts the edge of the light guide plate. A compression spring is sleeved on the outside of each sliding column to provide a continuous pressing force towards the light guide plate.

[0007] A heat dissipation assembly is installed on one side of the aluminum frame and is used for heat dissipation. A mounting plate is provided on one side of the mounting groove, and a rib is provided on one side of the mounting plate. Connecting strips are provided on both sides of the rib. The mounting plate, rib, and connecting strips are integrally formed to form a continuous heat conduction path.

[0008] Preferably, the two ends of the compression spring are fixed to the inner walls of the clamping block and the mounting groove, respectively.

[0009] Preferably, a plurality of side pressure blocks are provided on both sides of the pressure plate, and a locking pin is threadedly connected to the side pressure block, the locking pin being threadedly engaged with the lock hole on the aluminum frame.

[0010] Preferably, the connecting strip is provided with a plurality of heat dissipation fins.

[0011] Preferably, a heat dissipation groove is provided on the side of the aluminum frame near the mounting groove, and a ventilation opening is provided between the heat dissipation groove and the mounting groove.

[0012] Preferably, the surface of the clamping block is provided with an elastic protective layer to prevent the light guide plate from being scratched and displaced during the clamping process.

[0013] Preferably, the mounting plate, ribs, connecting strips, and aluminum frame are integrally extruded or die-cast.

[0014] The beneficial effects of this utility model are:

[0015] 1. This type of light guide plate mounting assembly for display cases, through its one-piece molded mounting plate, ribs, connecting strips, and aluminum frame, not only forms an efficient heat conduction path, but its structural strength also provides a rigid support foundation for the clamping spring in the limiting assembly, ensuring the stable application of clamping force. Conversely, the limiting assembly tightly presses the light guide plate onto the mounting surface, reducing the contact thermal resistance between the light guide plate and the mounting surface, further improving the efficiency of heat conduction to the heat dissipation assembly. The mutually reinforcing relationship between the mounting assembly and the heat dissipation assembly enhances the overall performance of this type of light guide plate mounting assembly for display cases.

[0016] 2. This light guide plate mounting assembly for display cases utilizes a double-safety structure of "elastic clamping + mechanical locking" to effectively prevent the light guide plate from loosening or shifting due to vibration or force during long-term use, ensuring stable coupling between the light guide plate and the light source. Specifically, it employs a limit component, utilizing the synergistic action of a pressure plate, sliding column, clamping block, and clamping spring to achieve automatic limiting and elastic clamping of the light guide plate. This effectively prevents the light guide plate from loosening or shifting due to vibration or force during long-term use of the display case. Furthermore, the threaded locking structure of the locking column and locking hole further enhances the reliability of the fixation, ensuring stable cooperation between the light guide plate and the light source.

[0017] 3. This light guide plate mounting assembly for display cases incorporates a heat dissipation component. The heat dissipation part uses an integrated mounting plate, ribs, and connecting strips to form a continuous heat conduction path, reducing interface thermal resistance and significantly improving heat dissipation efficiency and structural strength. At the same time, the aluminum frame is equipped with heat dissipation grooves and vertically connected ventilation openings to form a chimney effect for natural convection, improving heat dissipation efficiency, enhancing natural heat dissipation, and preventing heat accumulation in the light source that could shorten its lifespan, thereby improving the overall service life and operational stability of the display case.

[0018] 4. This type of light guide plate mounting assembly suitable for display cases has an elastic protective layer on the surface of the clamping block to prevent scratches on the light guide plate during installation and use, thereby improving its service life; and the locking pin adopts a hand-tightening structure to achieve tool-free quick disassembly, which is convenient for maintenance and replacement.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0027] like Figures 1 to 3 As shown, the light guide plate mounting assembly suitable for display cases includes: an aluminum frame 1; a limiting component, which is installed on one side of the aluminum frame 1 and is used to fix the position of the light guide plate; and a heat dissipation component, which is installed on one side of the aluminum frame 1 and is used for heat dissipation.

[0028] During the use of the display case, the light guide plate is fixed in place by inserting it into the mounting surface on the aluminum frame 1. After the light guide plate is inserted, the limiting component presses the edge of the light guide plate to prevent it from shifting under gravity or vibration, ensuring that the light guide plate can stably contact the light source and allow light to enter the interior of the light guide plate evenly to achieve the display lighting effect. At the same time, the light source generates heat during long-term operation. This heat is first conducted to the aluminum frame 1 through the light guide plate and mounting surface. The aluminum frame 1, as a metal skeleton, has good thermal conductivity and can quickly transfer the heat to the heat dissipation component. The heat dissipation component increases the contact area with the air through some structures and uses natural convection to dissipate the accumulated heat to the external environment, thereby reducing the temperature of the aluminum frame 1 and the light source area, preventing the LED lights from having a shortened lifespan due to heat accumulation, and maintaining a suitable temperature inside the display case. This allows the light guide plate to work stably for a long time, achieving a comprehensive effect of reliable fixation, uniform light effect, and efficient heat dissipation.

[0029] like Figure 1 , Figure 2As shown, the limiting component is used to fix the position of the light guide plate. The aluminum frame 1 is provided with a mounting groove 2 and a sliding hole 4 that passes through the mounting groove 2. A pressure plate 6 is slidably installed on one side of the aluminum frame 1. Several sliding posts 7 are fixed on the pressure plate 6. The end of the sliding post 7 is provided with a pressing block 9. The pressing block 9 is located in the mounting groove 2 and contacts the edge of the light guide plate. A compression spring 8 is sleeved on the outside of the sliding post 7. The two ends of the compression spring 8 are respectively fixed to the pressing block 9 and the inner wall of the mounting groove 2 to provide a continuous pressing force towards the light guide plate. Several side pressing blocks 10 are provided on the symmetrical sides of the pressure plate 6. Locking posts 11 are threadedly connected to the side pressing blocks 10. The locking posts 11 are threadedly engaged with the locking holes 12 on the aluminum frame 1. The surface of the pressing block 9 is provided with an elastic protective layer to prevent the light guide plate from being scratched and displaced during the pressing process.

[0030] During the installation of the light guide plate, the pressure plate 6, under the action of external force, drives the sliding column 7 to slide along the sliding hole 4 on the aluminum frame 1. The sliding column 7 pushes the clamping block 9 into the mounting groove 2 and gradually abuts against the side of the light guide plate, so that the light guide plate is positioned and fixed by the clamping action of the clamping block 9. The compression spring 8 installed on the outer sleeve of the sliding column 7 provides continuous rebound force in the compressed state, so that the clamping block 9 can stably press the light guide plate and prevent it from loosening or shifting during the use of the display case. At the same time, the side pressure blocks 10 on both sides of the pressure plate 6 are threadedly connected to the corresponding locking holes 12 on the aluminum frame 1 through the locking column 11. When the locking column 11 is tightened, the side pressure blocks 10 and the aluminum frame 1 form a reliable locking relationship, thereby restricting the free movement of the pressure plate 6 and the sliding column 7, so that the clamping block 9 maintains a stable pressing state under the action of the compression spring 8. This not only facilitates the installation and disassembly of the light guide plate, but also ensures the fixation reliability and safety of the light guide plate in the long-term working environment.

[0031] like Figure 3 As shown, a mounting plate 3 is provided on one side of the mounting groove 2, a rib 14 is provided on one side of the mounting plate 3, and connecting strips 16 are provided on both sides of the rib 14. The mounting plate 3, rib 14 and connecting strips 16 are integrally formed to form a continuous heat conduction path. Several heat dissipation fins 13 are provided on the connecting strips 16. A heat dissipation groove 15 is provided on the side of the aluminum frame 1 near the mounting groove 2. A ventilation opening 5 is provided between the heat dissipation groove 15 and the mounting groove 2. The mounting plate 3, rib 14, connecting strips 16 and aluminum frame 1 are integrally extruded or die-cast.

[0032] When the light strip is installed on the mounting plate 3 and is in operation, the heat generated is first conducted to the ribs 14 through the mounting plate 3, which is in close contact with it. The ribs 14 act as heat conduction channels, quickly transferring the heat to the connecting strips 16 on both sides. Then, the heat is diffused from the connecting strips 16 to several heat dissipation fins 13. The heat dissipation fins 13 have a large surface area and can fully contact the air, thereby accelerating the dissipation of heat to the external environment. At the same time, the aluminum frame 1 has a heat dissipation groove 15 on the side near the mounting groove 2. The vents 5 on the heat dissipation groove 15 are interconnected with the vents 5 on the mounting groove 2, forming an air flow channel. When the light source is working for a long time, hot air rises and is discharged naturally through the vents 5, while cold air enters from the other side to replenish it, realizing air convection heat exchange, further improving heat dissipation efficiency, and ensuring that the light strip and light guide plate can maintain a stable temperature during long-term operation. This avoids the shortening of the light source life or the increase of the internal temperature of the display case due to overheating, thereby achieving efficient heat dissipation and stable use effect.
