Description

Technical Field

[0001] This utility model relates to the field of LCD liquid crystal displays, and in particular to a modular disassembly device for LCD liquid crystal displays that is easy to maintain. Background Technology

[0002] LCD screens are display devices that use liquid crystal control to control light transmittance to achieve color display. LCDs have advantages such as small size, light weight, energy saving, and low radiation.

[0003] Disassembling and repairing LCD screens is a high-precision, high-risk operation, involving multiple layers of delicate structures such as the casing, front panel, LCD panel, backlight module, and driver circuit. Any mistake may lead to permanent damage such as screen leakage or backlight burn-out. Non-professionals should contact official after-sales service or a professional organization for assistance. Before proceeding, the risks must be clearly understood, and tools such as precision screwdrivers, plastic pry bars, suction cups, and anti-static wrist straps should be prepared. The operation should be carried out in a dust-free, dry workbench, ensuring that the equipment is completely powered off and any residual charge is discharged.

[0004] Traditional disassembly methods require additional tools such as screwdrivers to unscrew the frame screws one by one. Some hidden screws also require tearing off covering structures such as pads and labels. The process is cumbersome and the tools are inconvenient to carry and use. When separating the frame from the internal components, tools such as pry bars are often needed to pry open the gaps, which can easily result in violent disassembly. The electronic components inside the frame are delicate and fragile. Such operations can easily cause the components to be bumped, scratched, or even cause irreversible damage such as broken ribbon cables and damaged chips, which greatly increases the maintenance cost and the risk of equipment scrapping. At the same time, the complicated disassembly process also reduces maintenance efficiency. Therefore, a modular disassembly device for LCD screens that is easy to maintain is proposed to solve the above problems. Utility Model Content

[0036] 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.

[0037] Reference Figure 1 , Figure 4 , Figure 5 The present invention provides an embodiment of a modular disassembly device for an LCD screen that is easy to maintain. The device includes an LCD screen frame 1, with a disassembly mechanism 2 and an adjustment mechanism 3 inside the frame 1. The disassembly mechanism 2 includes a cover frame 211, which covers and protects the internal components of the LCD screen frame 1. A movable plate 212 is slidably connected to the inner wall of the cover frame 211. The movable plate 212 is a plate-shaped structure that can slide on the inner wall of the cover frame 211 and move other components. A connecting plate 213 is fixedly connected to the top of the movable plate 212, connecting the movable plate 212 and a locking block 214. A locking block 214 is fixedly connected to the outer wall of the connecting plate 213, and the locking block 214 is a block-shaped structure that can cooperate with a slot 215 to fix the cover frame 211. The inner wall of the LCD screen frame 1 is provided with a slot 215. The slot 215 is a groove-shaped structure for accommodating the block 214 to fix the cover frame 211. The inner wall of the slot 215 is slidably connected to the outer wall of the block 214. The outer wall of the moving plate 212 is fixedly connected with a pressure rod 216. The pressure rod 216 is a rod-shaped structure that drives the moving plate 212 to move after being squeezed by the arc-shaped extrusion groove 218. The outer wall of the cover frame 211 is rotatably connected with a rotating block 217. The rotating block 217 is a block-shaped structure that can be rotated to make the arc-shaped extrusion groove 218 squeeze the pressure rod 216. The inner wall of the rotating block 217 is provided with an arc-shaped extrusion groove 218. The arc-shaped extrusion groove 218 is an arc-shaped groove opened on the rotating block 217 to squeeze the pressure rod 216. The outer wall of the connecting plate 213 is elastically connected to the inner wall of the cover frame 211 by a spring 219.

[0038] Reference Figure 2 , Figure 4 , Figure 6The disassembly mechanism 2 also includes a handle 220, which is a handheld component that facilitates the user to rotate the rotating block 217. The outer wall of the handle 220 is fixedly connected to the outer wall of the rotating block 217. The outer wall of the pressure rod 216 is slidably connected to the inner wall of the arc-shaped extrusion groove 218. One end of the spring 219 is fixedly connected to the inner wall of the cover frame 211, and the other end of the spring 219 is fixedly connected to the outer wall of the connecting plate 213. The spring 219 is an elastic component that is compressed when the locking block 214 is disengaged from the locking groove 215 and can drive the locking block 214 to reset after the handle 220 is released.

[0039] Reference Figure 2 , Figure 3 The adjusting mechanism 3 includes a bidirectional screw 311, which is a rod-shaped structure that allows two moving blocks 312 to move closer or further apart by rotation. Both ends of the bidirectional screw 311 are rotatably connected to the outer wall of the cover frame 211. The outer wall of the bidirectional screw 311 is threadedly connected to the moving blocks 312 via threaded sleeves. The moving blocks 312 are block-shaped structures that can drive the connecting block 313 to move when the bidirectional screw 311 rotates. The adjusting mechanism 3 also includes a connecting block 313, which is a block-shaped structure that connects the moving blocks 312 and other adjusting components. The outer wall of the connecting block 313 is fixedly connected to the outer wall of the moving blocks 312. A threaded sleeve 314 is rotatably connected to the outer wall of the connecting block 313. The threaded sleeve 314 is a cylindrical structure that can drive the threaded rod 315 to rise and fall by rotation. The adjusting mechanism 3 also includes a threaded rod 315, which can drive the lifting block 316 to rise and fall when the threaded sleeve 314 rotates. The adjusting mechanism 3 includes a lowering rod-shaped structure, with the outer wall of the threaded rod 315 threadedly connected to the inner wall of the threaded sleeve 314. The adjusting mechanism 3 also includes a lifting block 316, which is a block structure that can slide on the inner wall of the connecting block 313 and drive the L-shaped positioning block 317 to rise and fall. The outer wall of the lifting block 316 is slidably connected to the inner wall of the connecting block 313, and the outer wall of the lifting block 316 is fixedly connected to one end of the threaded rod 315. The adjusting mechanism 3 also includes an L-shaped positioning block 317, which is an L-shaped block structure used to cooperate with a preset positioning hole to achieve device positioning and installation. The outer wall of the L-shaped positioning block 317 is fixedly connected to the outer wall of the lifting block 316. The adjusting mechanism 3 also includes a limiting rod 318, which is a rod-shaped structure used to limit the movement direction of the connecting block 313. Both ends of the limiting rod 318 are fixedly connected to the outer wall of the cover frame 211, and the outer wall of the limiting rod 318 is slidably connected to the inner wall of the connecting block 313.

[0040] Working principle: When it is necessary to disassemble and repair the electronic components inside the LCD screen frame 1, the rotating block 217 can be rotated by the handle 220, so that the rotating block 217 presses the pressure rod 216 through the arc-shaped pressing groove 218 and moves it. The pressure rod 216 drives the fixedly connected moving plate 212 to move on the inner wall of the cover frame 211, so that the moving plate 212 drives the connecting plate 213 and the locking block 214 to move synchronously, so that the spring 219 is compressed, and the locking block 214 is no longer in the inner wall of the locking groove 215. Then the cover frame 211 can be removed from the inner wall of the LCD screen frame 1 to facilitate the repair of the electronic components inside the LCD screen frame 1.

[0041] During installation of the LCD screen frame 1, by rotating the bidirectional screw 311, the two moving blocks 312 connected by the threaded sleeve on the outer wall of the bidirectional screw 311 move closer or further apart. This allows the lateral position of the four L-shaped positioning blocks 317 to be adjusted via the connecting block 313. The limiting rod 318 limits the movement of the connecting block 313. By rotating the threaded sleeve 314, the threaded sleeve 314 drives the threaded rod 315 to rotate, causing the threaded rod 315 to drive the lifting block 316 to rise and fall on the inner wall of the connecting block 313. This, in turn, adjusts the vertical position of the L-shaped positioning blocks 317, allowing the L-shaped positioning blocks 317 to be adjusted according to the position of the preset positioning holes.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
