Description

Technical Field

[0001] This utility model relates to the field of LED backlight module technology, specifically a concealed and aesthetically pleasing LED backlight screw structure. Background Technology

[0002] LED backlighting uses light-emitting diodes (LEDs) as the backlight source for an LCD screen. The liquid crystal itself does not emit light and requires a backlight to display images. LED backlighting provides uniform illumination to the LCD screen by controlling the emission of LEDs. When current passes through an LED, electrons and holes recombine, releasing energy and generating photons, which then emit light. This light is processed by optical components such as diffusers and light guides to evenly illuminate the back of the LCD screen.

[0003] LED backlights are typically installed and fixed using screws. However, traditional screws cannot be installed discreetly, the screw heads cannot be kept level with the LED backlight panel, and the protruding screw heads affect the aesthetics. In addition, the screw heads also have slots for easy rotation, which also affect the overall appearance. Furthermore, after being fixed, the screws are relatively easy to loosen from the screw holes, resulting in misalignment. To address these shortcomings, we propose a discreet and aesthetically pleasing LED backlight screw. Utility Model Content

[0004] One of the technical problems this application aims to solve is that traditional screws cannot be installed in a concealed manner, the screw head cannot be kept horizontal with the LED backlight panel, the protruding screw head will affect the aesthetics, and the screw head will also have a slot for rotation in order to facilitate rotation. The setting of the slot will also affect the overall aesthetics. Moreover, after the screw is fixed, it is also easy to loosen from the screw hole, which will lead to the deviation of the fixation. To address the aforementioned technical problems, this application provides a concealed and aesthetically pleasing LED backlight screw, comprising a carrier plate, an LED backlight panel fixedly mounted on the outer side of the carrier plate, a light source fixedly mounted on the outer side of the LED backlight panel, screw holes at the four corners of the outer side of the LED backlight panel, and screw rods threadedly connected to the four corners of the outer side of the LED backlight panel through the screw holes. Limiting grooves are formed on the upper and lower inner walls of the screw holes. A head is fixedly connected to one end of the screw rod, one end of which is flat and flush with the outer side of the LED backlight panel. A concealed component is disposed inside the head, and a limiting component is disposed inside the screw hole.

[0005] In some embodiments, the concealment component includes a triangular groove and a sliding groove, the triangular groove being formed on the outer side of the head and the sliding groove being formed on the inner wall of the triangular groove.

[0006] In some embodiments, the concealment assembly further includes a first spring and a sliding plate, one end of the first spring being fixedly connected to the inner wall of the groove, the outer side of the sliding plate being slidably connected to the inside of the groove, and one end of the sliding plate being fixedly connected to the other end of the first spring.

[0007] In some embodiments, the concealed assembly further includes a connecting rod and a triangular plate, one end of the connecting rod being fixedly connected to one end of the sliding plate, and one end of the triangular plate being fixedly connected to the other end of the connecting rod, wherein the triangular plate matches the model of the triangular groove.

[0008] In some embodiments, the limiting component includes a through hole and a second spring, the through hole being formed inside the screw and the second spring being disposed inside the through hole.

[0009] In some embodiments, the limiting component further includes a movable block and a limiting block. There are two movable blocks, which are respectively fixedly connected to the two ends of the second spring. One end of the limiting block is fixedly connected to the outside of the movable block. The limiting block is located inside the limiting groove, and the two sides of the limiting block are arc-shaped.

[0010] In some embodiments, the limiting component further includes a sliding groove and a sliding block. The sliding groove is formed on the inner wall of the through hole, and there are two sliding blocks. The two sliding blocks are respectively fixed on the outside of two movable blocks. The sliding blocks are located inside the sliding groove and are slidably connected to the sliding groove.

[0011] This utility model has at least the following beneficial effects: I. This utility model, through its concealed components, enables the concealed installation of screws. The triangular plate, placed within a triangular groove, seals the groove used for rotating the screw, creating a complete flat surface on the outer side of the head, resulting in a more aesthetically pleasing appearance. Furthermore, the triangular plate and the triangular groove are precision-machined, with consistent heights and minimal gaps between them—so small that they are imperceptible to the naked eye, thus achieving the concealed effect. When personnel need to rotate the screw, they can use a tool to push the triangular plate into the triangular groove, and then rotate the tool to drive the head and screw to rotate, without affecting the normal use of the screw.

[0012] Second, this utility model, through the setting of a limiting component, can limit the screw after it is fixed, preventing the screw from loosening in the screw hole. When the screw is rotated into the screw hole, due to the force of the second spring, the limiting block will be placed inside the limiting groove, thus fixing the position of the screw and preventing the screw from loosening.

[0016] 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.

[0017] like Figure 1-5 As shown, this utility model provides a technical solution: a concealed and aesthetically pleasing LED backlight screw, including a carrier plate 1, an LED backlight panel 2 fixedly installed on the outer side of the carrier plate 1, a light source 3 fixedly installed on the outer side of the LED backlight panel 2, screw holes 4 are provided at the four corners of the outer side of the LED backlight panel 2, screw rods 5 are threadedly connected to the four corners of the outer side of the LED backlight panel 2 through the screw holes 4, limit grooves 6 are provided on the upper and lower inner walls of the screw holes 4, a head 7 is fixedly connected to one end of the screw rod 5, one end of the head 7 is flat and flush with the outer side of the LED backlight panel 2, a concealed component 8 is provided inside the head 7, and a limit component 9 is provided inside the screw holes 4; The screw consists of two parts: a screw rod 5 and a head 7. The LED backlight panel 2 is fixed to the carrier plate 1 by the screw. The slot on the outside of the head 7 for rotation can be sealed by the concealed component 8, so that the outside of the head 7 forms a complete plane, making the overall appearance more beautiful and achieving the concealed effect. The screw is installed in a concealed manner. The limit component 9 can limit the screw after it is fixed, preventing the screw from loosening in the screw hole 4.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the concealed component 8 includes a triangular groove 801, a sliding groove 802, a first spring 803, a sliding plate 804, a connecting rod 805, and a triangular plate 806. The triangular groove 801 is formed on the outer side of the head 7, and the sliding groove 802 is formed on the inner wall of the triangular groove 801. One end of the first spring 803 is fixedly connected to the inner wall of the sliding groove 802. The outer side of the sliding plate 804 is slidably connected to the inside of the sliding groove 802. One end of the sliding plate 804 is fixedly connected to the other end of the first spring 803. One end of the connecting rod 805 is fixedly connected to one end of the sliding plate 804. One end of the triangular plate 806 is fixedly connected to the other end of the connecting rod 805. The model of the triangular plate 806 matches that of the triangular groove 801. The triangular plate 806 and the triangular groove 801 are precision machined, with the same height and a small gap between them. When the gap is so small that it cannot be detected by the naked eye, it can achieve a concealed effect. When the personnel need to rotate the screw later, they can use a tool to push the triangular plate 806 into the inside of the triangular groove 801. Then, the personnel can rotate the tool to drive the head 7 and the screw 5 to rotate without affecting the normal use of the screw.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the limiting component 9 includes a through hole 901, a second spring 902, a movable block 903, a limiting block 904, a sliding groove 905, and a sliding block 906. The through hole 901 is opened inside the screw 5. The second spring 902 is disposed inside the through hole 901. There are two movable blocks 903, which are respectively fixedly connected to the two ends of the second spring 902. One end of the limiting block 904 is fixedly connected to the outside of the movable block 903. The limiting block 904 is located inside the limiting groove 6. The two sides of the limiting block 904 are arc-shaped. The sliding groove 905 is opened on the inner wall of the through hole 901. There are two sliding blocks 906, which are respectively fixed to the outside of the two movable blocks 903. The sliding block 906 is located inside the sliding groove 905 and is slidably connected to the sliding groove 905. When the screw 5 is rotated into the screw hole 4, the force of the second spring 902 will place the limiting block 904 inside the limiting groove 6, which will fix the position of the screw 5 and prevent the screw from loosening. When the screw 5 is rotated, the limiting block 904 will be squeezed and moved into the through hole 901, which will drive the movable block 903 to move, and then drive the sliding block 906 to slide in the sliding groove 905, increasing stability.

[0020] Working principle: During use, the screw consists of two parts: a screw rod 5 and a head 7. After installation, the outer side of the head 7 is horizontal, maintaining a horizontal alignment with the outer side of the LED backlight panel 2, preventing the head 7 from protruding and affecting aesthetics. Furthermore, a triangular plate 806 is positioned within a triangular groove 801, effectively sealing the groove for rotating the screw, thus forming a complete flat surface on the outer side of the head 7. When the color of the head 7 matches that of the LED backlight panel 2, the overall appearance is more aesthetically pleasing. Simultaneously, the triangular plate 806 and the triangular groove 801 are precision-machined, and their height... When the gap between the two is small enough to be imperceptible to the naked eye, it can achieve a concealed effect. When the personnel need to rotate the screw, they can use a tool to push the triangular plate 806 into the inside of the triangular groove 801. At the same time, the force is transmitted from the connecting rod 805 and the sliding plate 804 to the first spring 803, causing the first spring 803 to be compressed and deformed. After the triangular plate 806 enters the inside of the triangular groove 801, the personnel can rotate the tool to drive the head 7 and the screw 5 to rotate without affecting the normal use of the screw. When the screw 5 is rotated into the screw hole 4, the force of the second spring 902 will place the limiting block 904 into the limiting groove 6, thus fixing the position of the screw 5 and preventing the screw from loosening. Since the limiting block 904 is trapezoidal in shape and has an arc-shaped edge, when the screw 5 is slowly rotated, the limiting block 904 will be squeezed into the through hole 901, without affecting the removal of the screw.
