Description

Technical Field

[0001] This utility model relates to the field of backlight mounting technology, specifically to an LCD backlight panel mounting mechanism. Background Technology

[0002] When disassembling the LED backlight and backlight panel of a display screen, it is necessary to unscrew the bolts or pull the backlight panel with adhesive to disassemble and install the LED backlight. This operation is cumbersome and inconvenient. Here, an LCD backlight panel installation mechanism is proposed. Utility Model Content

[0003] The purpose of this invention is to provide an LCD backlight panel mounting mechanism to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An LCD backlight panel mounting mechanism includes a housing mechanism, a limiting mechanism fixedly connected to the housing mechanism, and a positioning mechanism provided inside the housing mechanism.

[0006] The limiting mechanism includes a baffle, a connecting rod is rotatably connected inside the baffle, spring plates are fixedly connected to both sides of the baffle, and an arc-shaped locking block is fixedly connected to the outside of the spring plates.

[0007] A further improvement of this utility model is that: the arc-shaped locking block is fixedly connected to the outside of the baffle, a pull ring is provided on the front side of the baffle, and an anti-slip pad is fixedly connected to the bottom of the baffle. The anti-slip pad can increase the friction between the baffle and the limiting groove, thereby improving the stability of the baffle.

[0008] A further improvement of the present invention is that the housing mechanism includes an outer frame, a limiting groove is provided on one side of the outer frame, an arc-shaped slot is provided on the inner wall of the outer frame, and support grooves are symmetrically provided on the inner wall of the outer frame. An LCD backlight panel is provided inside the outer frame. By placing the LCD backlight panel into the outer frame, the position of the LCD backlight panel can be initially fixed.

[0009] A further improvement of this utility model is that: both ends of the connecting rod are fixedly connected to the inner wall of the outer frame; one end of the baffle and the anti-slip pad are movably connected inside the limiting groove; the arc-shaped locking block is movably connected inside the arc-shaped locking groove; the arc-shaped locking groove fixes the position of the arc-shaped locking block; at the same time, the outer frame fixes the position of the connecting rod; the two cooperate to fix the position of the baffle.

[0010] A further improvement of the present invention is that the positioning mechanism includes an electric rotating rod, a drive motor is installed inside the electric rotating rod, and a threaded rod is fixedly connected to one end of the electric rotating rod. When the electric rotating rod runs, it can drive the threaded rod to rotate synchronously.

[0011] A further improvement of this utility model is that: both the electric rotating rod and the threaded rod are rotatably connected in the support groove, and the surface of the threaded rod is threadedly connected to a threaded connecting block. The thread inside the threaded connecting block is in contact with the thread on the surface of the threaded rod, so that the height of the threaded connecting block can be adjusted by rotating the threaded rod.

[0012] A further improvement of this utility model is that a positioning frame is fixedly connected to one side of the threaded connecting block, and a rubber pad is fixedly connected to the lower surface of the positioning frame. The rubber pad is in contact with the LCD backlight panel, thereby preventing the positioning frame from damaging the LCD backlight panel.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. This utility model provides an LCD backlight panel mounting mechanism. The bottom of the baffle is pressed into the limiting groove, simultaneously moving the arc-shaped locking block into the arc-shaped slot. After the pressure on the spring plate disappears, it returns to its original shape, thus supporting the interior of the arc-shaped locking block. This causes the arc-shaped locking block to adhere to the inner wall of the arc-shaped slot, thereby sealing the perimeter of the outer frame and allowing the LCD backlight panel to be installed. Pulling the pull ring outward causes the baffle to rotate outward around the connecting rod axis, moving the arc-shaped locking block out of the arc-shaped slot, opening one side of the outer frame and facilitating the removal of the LCD backlight panel, thus achieving a convenient disassembly and assembly effect.

[0015] 2. This utility model provides an LCD backlight panel mounting mechanism. Activating the electric rotating rod drives the threaded rod to rotate synchronously. The threaded shape of the inner wall of the threaded connecting block fits against the surface of the threaded rod. As the threaded rod rotates, the position of the threaded connecting block can be adjusted, thereby adjusting the height of the positioning frame and the rubber pad, and consequently adjusting the width between the rubber pad and the bottom of the outer frame. This allows for the installation and fixing of LCD backlight panels of different thicknesses, thus expanding the applicability of the mounting mechanism. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to embodiments:

[0022] Example 1

[0023] like Figure 1-4 As shown, this utility model provides an LCD backlight panel mounting mechanism, including a housing mechanism 2, a limiting mechanism 1 fixedly connected to the housing mechanism 2, a positioning mechanism 3 provided inside the housing mechanism 2, the limiting mechanism 1 including a baffle 11, a connecting rod 12 rotatably connected inside the baffle 11, spring plates 13 fixedly connected to both sides of the baffle 11, an arc-shaped locking block 14 fixedly connected to the outer side of the spring plates 13, the arc-shaped locking block 14 fixedly connected to the outer side of the baffle 11, a pull ring 15 opened on the front side of the baffle 11, and an anti-slip pad 16 fixedly connected to the bottom of the baffle 11;

[0024] Specifically, the LCD backlight panel 25 is inserted along the inner wall of the outer frame 21, and the bottom of the baffle 11 is pressed into the limiting groove 22. At the same time, the arc-shaped locking block 14 is moved into the arc-shaped locking groove 23. After the pressure on the spring sheet 13 is released, it returns to its original shape, thereby supporting the interior of the arc-shaped locking block 14. This allows the arc-shaped locking block 14 to adhere to the inner wall of the arc-shaped locking groove 23. Meanwhile, the anti-slip pad 16 can increase the friction between itself and the limiting groove 22. The two work together to improve the fixing strength of the baffle 11, thereby sealing the perimeter of the outer frame 21. The position of the LCD backlight panel 25 can then be installed. Pulling the pull ring 15 outward causes the baffle 11 to rotate outward about the connecting rod 12 as the axis, moving the arc-shaped locking block 14 out of the arc-shaped locking groove 23. This opens one side of the outer frame 21, making it easier to remove the LCD backlight panel 25, thus achieving the effect of easy disassembly and assembly.

[0025] Example 2

[0026] like Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the housing mechanism 2 includes an outer frame 21, a limiting groove 22 is provided on one side of the outer frame 21, an arc-shaped slot 23 is provided on the inner wall of the outer frame 21, support grooves 24 are symmetrically provided on the inner wall of the outer frame 21, an LCD backlight panel 25 is provided inside the outer frame 21, the two ends of the connecting rod 12 are fixedly connected to the inner wall of the outer frame 21, one end of the baffle 11 and the anti-slip pad 16 are movably connected inside the limiting groove 22, and the arc-shaped block 14 is movably connected inside the arc-shaped slot 23;

[0027] Specifically, the outer frame 21 fixes the position of the LCD backlight panel 25, the arc-shaped slot 23 fixes the position of the arc-shaped block 14, and the outer frame 21 fixes the position of the connecting rod 12. The two work together to fix the position of the baffle 11.

[0028] Example 3

[0029] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the positioning mechanism 3 includes an electric rotating rod 31, a drive motor is provided inside the electric rotating rod 31, a threaded rod 32 is fixedly connected to one end of the electric rotating rod 31, the electric rotating rod 31 and the threaded rod 32 are rotatably connected in the support groove 24, a threaded connecting block 33 is threadedly connected to the surface of the threaded rod 32, a positioning frame 34 is fixedly connected to one side of the threaded connecting block 33, and a rubber pad 35 is fixedly connected to the lower surface of the positioning frame 34;

[0030] Specifically, the drive motor provides driving force to the electric rotating rod 31, thereby starting the electric rotating rod 31 and driving the threaded rod 32 to rotate synchronously. The threaded shape of the inner wall of the threaded connecting block 33 fits with the surface of the threaded rod 32. As the threaded rod 32 rotates, the position of the threaded connecting block 33 can be adjusted, thereby adjusting the height of the positioning frame 34 and the rubber pad 35, and then adjusting the width of the rubber pad 35 relative to the bottom of the outer frame 21. This allows for the installation and fixing of LCD backlight panels 25 of different thicknesses, thus expanding the applicability of the installation mechanism. After the LCD backlight panel 25 is placed inside the outer frame 21, the threaded rod 32 drives the threaded connecting block 33 to move down, so that the rubber pad 35 comes into contact with the LCD backlight panel 25, thereby fixing the position of the LCD backlight panel 25.

[0031] The working principle of this LCD backlight panel mounting mechanism will be explained in detail below.

[0032] like Figure 1-4As shown, the LCD backlight panel 25 is inserted along the inner wall of the outer frame 21. The bottom of the baffle 11 is pressed into the limiting groove 22, simultaneously moving the arc-shaped locking block 14 into the arc-shaped locking groove 23. After the pressure on the spring sheet 13 is released, it returns to its original shape, thus supporting the interior of the arc-shaped locking block 14, making the arc-shaped locking block 14 adhere to the inner wall of the arc-shaped locking groove 23. At the same time, the anti-slip pad 16 can increase the friction between itself and the limiting groove 22. Thus, the two work together to improve the fixing strength of the baffle 11, thereby sealing the perimeter of the outer frame 21, and the LCD backlight panel 25 can be installed. When the electric rotating rod 31 is started, it can drive the threaded rod 32 to rotate synchronously. The threaded shape of the inner wall of the threaded connecting block 33 fits with the surface of the threaded rod 32. As the threaded rod 32 rotates, the position of the threaded connecting block 33 can be adjusted, thereby adjusting the height of the positioning frame 34 and the rubber pad 35, and then adjusting the width of the rubber pad 35 and the bottom of the outer frame 21. This allows for the installation and fixing of LCD backlight panels 25 of different thicknesses. The threaded rod 32 drives the threaded connecting block 33 to move down, so that the rubber pad 35 is in contact with the LCD backlight panel 25, thus fixing the position of the LCD backlight panel 25.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
