Therefore, the aluminum substrate is easily affected by the holding position during installation or movement. If it is not held properly, it is likely to cause one side to fall and be damaged. Therefore, a thin and light LED backlight module is proposed to address the above problems. Utility Model Content

[0015] The effect achieved by the above components is that the rubber protective pad has a certain elasticity and flexibility, which can prevent the U-shaped plate from causing surface damage when squeezing and limiting the aluminum substrate.

[0016] Preferably, a guide plate is fixedly connected to the surface of the U-shaped frame, and the position of the guide plate is parallel to the aluminum substrate.

[0017] The effect achieved by the above components is that the position of the U-shaped frame on the surface of the aluminum template can be controlled by arranging the guide plate.

[0018] Preferably, one end of the round rod is fixedly connected to a setting plate, and the setting plate is elliptical in shape.

[0019] The effect achieved by the above components is: rotating the setting plate drives the round rod to rotate in the semicircular plate, and the round rod drives the limit block to rotate until the limit block slides into the L-shaped plate slot, so that the staff can stably rotate the round rod to accurately control the position of the limit block and the L-shaped plate slot.

[0020] In summary, the beneficial effects of the present invention are as follows:

[0021] In the utility model, the effect of supporting the aluminum substrate is achieved. Due to the characteristics of the thin and light aluminum substrate itself, its adhesive layer is relatively thin, and LED lamp beads are installed on the internal surface. Therefore, the aluminum substrate is easily affected by the holding position during installation or movement. If it is not held properly, it is likely to cause one side to fall and be damaged, thereby improving the stability and safety of the aluminum substrate in the entire operation process.

[0027] Reference Figure 1-4 As shown, the utility model provides a technical solution: a thin and light LED backlight module, comprising an aluminum substrate 1, an inner surface of the aluminum substrate 1 is installed with LED lamp beads 2, the surface of the aluminum substrate 1 is slidably connected to two U-shaped frames 3, the surfaces of the two U-shaped frames 3 are provided with two mounting grooves, the inner surface of the mounting groove of the U-shaped frame 3 is fixedly connected with a short rod 4, the arc surface of the short rod 4 is rotatably connected with an L-shaped plate 5, the surface of the U-shaped frame 3 is fixedly connected with a semicircular plate 6, a round rod 7 is slidably inserted in the semicircular plate 6, one end of the round rod 7 is fixedly connected to a limiting block 8, a card slot is provided on the surface of the L-shaped plate 5, a rectangular block 9 is fixedly connected to the surface of the semicircular plate 6, a threaded rod 10 is inserted into the inner thread of the rectangular block 9, one end of the threaded rod 10 is rotatably connected to the semicircular block 11, and the surface of the semicircular block 11 abuts against the round rod 7. The effect of supporting the aluminum substrate 1 is achieved. Due to the characteristics of the thin and light aluminum substrate 1 itself, its adhesive layer is relatively thin, and LED lamp beads are installed on the internal surface. Therefore, the aluminum substrate 1 is easily affected by the holding position during installation or movement. If it is not held properly, it is likely to cause one side to fall and be damaged. This improves the stability and safety of the aluminum substrate 1 during the entire operation process. A limit rod 12 is slidably inserted into the rectangular block 9, and one end of the limit rod 12 is fixedly connected to the semicircular plate 6. The threaded rod 10 is rotated in the rectangular block 9, and the threaded rod 10 drives the semicircular plate 6 to move. The semicircular plate 6 drives the limit rod 12 to slide in the rectangular block 9, making the movement path of the semicircular plate 6 more stable and preventing it from rotating with the rotation of the threaded rod 10. The end of the threaded rod 10 away from the semicircular plate 6 is fixedly connected to a handle 13. The size of the limit block 8 is compatible with the size of the card slot of the L-shaped plate 5. Turning the handle 13 causes the threaded rod 10 to rotate within the rectangular block 9, which in turn moves the semicircular plate 6, allowing the operator to steadily rotate the threaded rod 10 and precisely control the tightening of the round rod 7. Two torsion springs 14 are mounted on the arc surface of the short rod 4. The ends of the torsion springs 14 are fixedly connected to the inner surfaces of the mounting slots of the L-shaped plate 5 and the U-shaped frame 3, respectively. The torque of the torsion springs 14 automatically rotates the L-shaped plate 5 on the arc surface of the short rod 4 and maintains its position, without hindering the lifting and lowering of the U-shaped frame 3. A protective pad 15 made of rubber is fixedly attached to the surface of the U-shaped frame 3. This rubber pad 15 has a certain degree of elasticity and flexibility, preventing surface damage caused by the U-shaped plate squeezing and limiting the aluminum substrate 1. A guide plate 16 is fixedly attached to the surface of the U-shaped frame 3, positioned parallel to the aluminum substrate 1. This guide plate 16 controls the position of the U-shaped frame 3 on the aluminum template surface. An elliptical setting plate 17 is fixedly attached to one end of the round rod 7. The rotating setting plate 17 drives the round rod 7 to rotate in the semicircular plate 6, and the round rod 7 drives the limit block 8 to rotate until the limit block 8 slides in the slot of the L-shaped plate 5, so that the staff can stably rotate the round rod 7 and accurately control the position of the limit block 8 and the slot of the L-shaped plate 5.

[0028] Working principle: when the staff needs to support the aluminum substrate 1, they push the U-shaped frame 3 to drive the guide plate 16 to guide until the guide plate 16 contacts the inner surface of the aluminum substrate 1. At this time, the L-shaped plate 5 rotates on the arc surface of the short rod 4, and the setting plate 17 is pushed to drive the round rod 7 to slide in the semicircular plate 6. At this time, the position of the limit block 8 and the position of the L-shaped plate 5 slot are aligned, and then continue to move downward, and rotate the round rod 7. At this time, the position of the limit block 8 and the L-shaped plate 5 slot is misaligned, and the handle 13 is turned to drive the threaded rod 10 to rotate in the rectangular block 9. The threaded rod 10 is The movable semicircular plate 6 moves, and the semicircular plate 6 drives the limiting rod 12 to slide in the rectangular block 9 until the semicircular plate 6 abuts against the round rod 7 to limit the position, thereby achieving the effect of supporting the aluminum substrate 1. Due to the characteristics of the thin and light aluminum substrate 1 itself, its adhesive layer is relatively thin, and LED lamp beads are installed on the internal surface. Therefore, the aluminum substrate 1 is easily affected by the holding position during installation or movement. If it is not held properly, it is likely to cause one side to fall and be damaged, thereby improving the stability and safety of the aluminum substrate 1 in the entire operation process.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
