Description

Technical Field

[0001] This utility model relates to the field of television technology, and in particular to a television diaphragm limiting device. Background Technology

[0002] In the backlight module of an LCD TV, films such as brightness enhancement films and diffusion films need to be fixed to the diffusion plate, such as... Figure 1 The TV back panel shown includes horizontally placed and stacked L-shaped part one and L-shaped part two. The top ends of L-shaped part one and L-shaped part two are connected, forming a space for accommodating the diaphragm and diffuser plate. Currently, the traditional fixing method commonly used in the industry is to use an adhesive to directly glue the edge of the diaphragm to the diffuser plate, and then use an adhesive to glue the diffuser plate and diaphragm to the TV back panel.

[0003] However, this adhesive method has significant technical drawbacks. When a television is turned on, it continuously generates heat, causing the temperature of the diffuser plate and the film to rise. Under prolonged exposure to heat, the physical properties of the adhesive material gradually deteriorate, its adhesiveness decreases, and it may eventually lose its adhesive function completely. Once the adhesive material fails, the film may shift, warp, or even detach due to its own stress or external vibrations. This not only causes serious defects such as bright spots, dark areas, and moiré patterns on the screen, affecting the viewing experience, but also requires significant manpower for realigning and reattaching the film during repairs, resulting in reduced production efficiency and increased maintenance costs.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0019] This application provides a television diaphragm 3 limiting device, referring to... Figure 1 , Figure 3 and Figure 5 The device includes a television back panel, comprising a horizontally stacked L-shaped portion 1 and an L-shaped portion 2, with L-shaped portion 1 positioned above L-shaped portion 2. The top ends of L-shaped portion 1 and L-shaped portion 2 are connected, forming a space 5 for accommodating a diaphragm 3 and a diffuser plate 4; it also includes: A U-shaped frame consisting of a bottom 6, a side 7, and a top 8, wherein the side 7 has a thickness for forming a space 9 to accommodate the diaphragm 3 and the diffuser plate 4; wherein the frame is engaged within the space 5, more specifically, after the diaphragm 3 and the diffuser plate 4 are stacked, their ends are placed flat within the space 9, the buckle 10 is used to fix the relative position of the frame and the TV back panel, and the fastener 11 is used to fix the relative position of the diaphragm 3 and the diffuser plate 4 with the frame, thereby the frame plays the role of fixing the position of the diaphragm 3 and the diffuser plate 4 with the TV back panel; The top 8 is provided with a buckle 10 for fixing the frame and a fastener 11 for fixing the diaphragm 3 and the diffuser plate 4. More specifically, the fastener 11 and the buckle 10 are spaced apart to prevent the distance between them from being too small and affecting their movement. When the frame is fixed in position with the diaphragm 3 and the diffuser plate 4, refer to Figure 5 and Figure 6 The bottom 6 contacts the L-shaped part 2, the top wall of the bottom 6 supports the diffuser plate 4, and the fastener 11 is used to prevent the diaphragm 3 and the diffuser plate 4 from being displaced longitudinally or horizontally relative to the frame. The specific usage process of this device is as follows: First, the stacked diaphragm 3 and diffuser plate 4 are placed into the space 9 of the frame. The diffuser plate 4 is supported by the bottom 6 of the frame, and the relative position of the two is locked by the fastener 11 of the top 8 to prevent displacement. Then, the assembled frame is inserted into the space 5 of the TV back panel, and the final fixation is completed by the buckle 10, so that the diaphragm 3 and diffuser plate 4 are firmly fixed on the TV back panel by the mechanical structure without the need for adhesive tape.

[0020] As a preferred embodiment of the above, refer to Figure 2 and Figure 5 The L-shaped part 1 has a through hole 12, which is located in the horizontal part of the L-shaped part 1. When the frame is locked in the space 5, the top wall of the top 8 contacts the horizontal part of the L-shaped part 1, and the bottom wall of the bottom 6 contacts the top wall of the horizontal part of the L-shaped part 2. One end of the buckle 10 is connected to the top 8, and the other end is curved upwards. More specifically, the buckle 10 and the top 8 are integrally formed. When the frame is fixed to the TV back panel, the clip 10 is engaged in the through hole 12; The specific operation process of the buckle 10 is as follows: When the frame is installed on the TV back panel, the side 7 is aligned with the space 5 of the TV back panel and enters the space 5. When the frame is in the space 5, the top wall of the top 8 contacts the horizontal part of the L-shaped part 1, and the bottom wall of the bottom 6 contacts the top wall of the horizontal part of the L-shaped part 2. One end of the buckle 10 is connected to the top 8, and the other end is tilted upward. Therefore, the other end of the buckle 10 will first undergo elastic deformation downward during the installation process. After the frame reaches the designated position, the buckle 10 returns to its initial shape, and the tilted end of the buckle 10 penetrates into the through hole 12. When the buckle 10 tends to move in the opposite direction, the upward-curved end of the buckle 10 abuts against the inner wall of the through hole 12 to prevent it from moving. When it is necessary to remove the frame, press down on the upward-curved end of the buckle 10 so that it is lower than the L-shaped part 1, and then pull out the frame to complete the removal.

[0021] As a preferred embodiment of the above, refer to Figure 7 The top 8 and the side 7 have notches 13. One end of the fastener 11 is fixedly connected to the notch 13, and the other end is inclined towards the bottom 6. The diaphragm 3 and the diffuser plate 4 are provided with positioning holes 14. The other end of the fixing member 11 extends into the positioning hole 14 and abuts against the diaphragm 3 and the diffuser plate 4. More specifically, when the diaphragm 3 and the diffuser plate 4 are stacked, their respective positioning holes 14 are connected. The specific operation process of the fastener 11 is as follows: Before the frame is placed into the TV back panel, the diffuser plate 4 and the diaphragm 3 are stacked manually and their positioning holes 14 are connected. Then the diffuser plate 4 and the diaphragm 3 are placed into the space 2 9. The other end of the fastener 11 is inserted into the positioning hole 14 by adjusting the angle or position of the diffuser plate 4 and the diaphragm 3. Then the frame with the diffuser plate 4 and the diaphragm 3 fixed is placed into the space 1 5. When in use, the other end of the fastener 11 extends into the positioning hole 14, preventing the diffuser plate 4 and the diaphragm 3 from detaching from the frame.

[0022] As a preferred embodiment of the above, refer to Figure 6 and Figure 7 The other end of the fastener 11 extends upward to form a vertical part 15, and the vertical part 15 contacts the inner wall of the positioning hole 14; By setting a vertical part 15, which has a certain length in the vertical direction, when the other end of the fixing member 11 is in the positioning hole 14, the vertical part 15 is in contact with the inner wall of the positioning hole 14 of the diffuser plate 4 and the diaphragm 3, thus preventing the two from shifting.

[0023] Since there is no vertical restraint on the diffuser plate 4 and the diaphragm 3, they may separate. As a preferred embodiment, the vertical portion 15 extends to the side portion 7 to form a horizontal portion 16, which abuts against the top wall of the diaphragm 3. When the other end of the fixing member 11 is in the positioning hole 14, the horizontal part 16 abuts against the top wall of the diaphragm 3, which can prevent the diffuser plate 4 from separating from the diaphragm 3, and the horizontal part 16 has a certain distance from the bottom wall of the top 8.

[0024] As a preferred embodiment of the above, refer to Figure 7 There is a gap 17 between the side wall of the buckle 10 and the top 8; By providing a gap 17 between the side wall and top 8 of the buckle 10, the impact of the buckle 10 on other parts, especially the fastener 11, when it undergoes elastic deformation can be reduced, so as to prevent the fastener 11 from damaging the diffuser plate 4 and the diaphragm 3 when its angle changes.

[0025] As a preferred embodiment of the above, the frame, buckle 10 and fastener 11 are made of materials that can undergo elastic deformation, such as high-performance engineering plastics, spring steel or stainless steel.

[0026] As a preferred embodiment of the above, refer to Figure 7 Each frame is provided with at least two buckles 10 and fasteners 11, which can apply a balanced clamping force to the diaphragm 3 and diffuser plate 4 assembly from both sides, effectively preventing single-end warping or overall displacement when the force is uneven.

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.
