[0002] Modular splicing LCD displays, also known as LCD video walls, can be used as individual monitors or spliced ​​together to form a super-large screen. Depending on different usage needs, they can be made into large or small screens.

[0003] According to the announcement number CN221570179U, a modular monitoring LCD display screen that can be assembled and spliced ​​is disclosed, which relates to the field of LCD display technology. The screen includes a display, one end of which has a support member, and a splicing column is sleeved on the surface of the support member. A circular plate is attached to one side of the splicing column. The bottom of the display has a splicing block, which is connected to a splicing track. A connecting tube is sleeved on the surface of the splicing column, and a rotating rod is rotatably connected to the top of the connecting tube. A rotating block is rotatably connected to one end of the rotating rod, and a fixed plate is provided at one end of the rotating block. The support member can support the splicing column and connect it to the display. Because the circular plate is attached to the splicing column, the splicing column and the circular plate can be assembled and connected. The splicing block and the splicing track can be used to assemble and connect the display. The connecting tube can reinforce and support the splicing columns, making the assembled display more stable. The rotating rod and the rotating block can be used to move and assemble the fixed plate.

[0004] The above-mentioned device achieves rapid docking between modules by fitting the assembly column and the circular plate together. The overall structure is easy to assemble and disassemble. According to the instruction manual and the attached drawings, the assembly column and the support are fixed only by surface fitting. Stability is guaranteed by processing precision. Long-term use may cause loosening due to vibration or wear. Utility Model Content

[0005] The purpose of this utility model is to provide a modular assembly structure for LCD screens that is easy to maintain, in order to solve the problem that the assembly columns and support components are only fixed by surface fitting, which relies on processing precision to ensure stability and is prone to loosening due to vibration or wear after long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular assembly structure for an easy-to-maintain LCD screen, comprising a support member fixedly installed at one end of the display body, an assembly column slidably sleeved with the support member, and a fixing plate. A fixing block is fixedly installed at the top of the support member, and a rotating gear is rotatably connected inside the fixing block. A toothed block is provided at the top of the assembly column, and the toothed block meshes with the rotating gear. A limiting half gear is rotatably connected inside the fixing block. A connecting rod is fixedly installed at one end of the limiting half gear, and a pull handle is fixedly installed at the top of the connecting rod. A first connecting shaft is fixedly installed inside the fixing block, and a second connecting shaft is fixedly installed at one end of the connecting rod. A connecting spring is fixedly installed between the first and second connecting shafts.

[0007] As a further embodiment of this utility model: a stop block is fixedly installed at one end of the connecting rod, and the two ends of the connecting rod are symmetrically fixedly installed on the stop block. A stop groove is symmetrically opened at the top of the fixed block, and the stop block is adapted to the stop groove.

[0008] As a further improvement of this utility model: a limiting block is slidably connected inside the stop block, a limiting slot is formed inside the stop groove, and the limiting block is adapted to the limiting slot.

[0009] As a further improvement of this utility model: a damping spring is fixedly installed inside the stop block, and one end of the damping spring is fixedly installed with the limiting block.

[0010] As a further improvement of this utility model: a pull rod is slidably connected to the top of the stop block, and the pull rod is fixedly installed to the top of the limiting block.

[0011] As a further improvement of this utility model: an assembly block is fixedly installed at the bottom of the display body, and a sliding rail is slidably connected to the bottom of the assembly block.

[0012] As a further embodiment of this utility model: connecting pipes are symmetrically arranged on the outer periphery of the assembly column, rotating blocks are symmetrically arranged at both ends of the fixing plate, and a rotating rod is arranged in the middle of the connecting pipes and rotating blocks.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The first layer of this utility model locks the axial movement of the assembly column by meshing the limiting half gear with the rotating gear, preventing relative sliding caused by vibration. The second layer restricts the rotation of the connecting rod by engaging the limiting block with the limiting slot, preventing the limiting half gear from disengaging. The double locking structure does not rely on high-precision machining, thus improving the reliability of the structure.

[0015] This invention allows for the release of the second locking mechanism by pulling the lever, and the release of the first locking mechanism by pulling the handle upwards. The components can then be separated by sliding the assembly column, eliminating the need to disassemble the overall structure. This quick and efficient disassembly process significantly reduces maintenance time for the LCD module, lowers maintenance costs, and improves equipment utilization. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0025] Reference Figures 1 to 6 In this embodiment of the utility model, a modular assembly structure for easy maintenance of a liquid crystal display screen includes a support member 3 fixedly installed at one end of the display body 1, an assembly column 2 slidably sleeved with the support member 3, and a fixing plate 23. A fixing block 5 is fixedly installed at the top of the support member 3, and a rotating gear 6 is rotatably connected inside the fixing block 5. A toothed block 4 is provided at the top of the assembly column 2, and the toothed block 4 is meshed with the rotating gear 6. A limiting half gear 7 is rotatably connected inside the fixing block 5. A connecting rod 8 is fixedly installed at one end of the limiting half gear 7. A pull handle 9 is fixedly installed at the top of the connecting rod 8. A first connecting shaft 10 is fixedly installed inside the fixing block 5. A second connecting shaft 11 is fixedly installed at one end of the connecting rod 8. A connecting spring 18 is fixedly installed in the middle of the first connecting shaft 10 and the second connecting shaft 11.

[0026] The above-mentioned solution is adopted as follows: the display body 1, support 3, assembly column 2, and fixing plate 23 are all prior art referenced in the prior art documents and are not described in detail in this application. The fixing block 5 welded to the top of the support 3 is made of 45# steel. The rotating gear 6, which is rotatably connected by a deep groove ball bearing, is made of 20CrMnTi alloy steel. The tooth block 4 integrally formed at the top of the assembly column 2 precisely meshes with the rotating gear 6. The limiting half gear 7, which is rotatably connected by a bearing inside the fixing block 5, is made of the same material and process as the rotating gear 6. The connecting rod 8 welded to one end is made of stainless steel and is not easy to bend. The pull handle 9 welded to the top of the connecting rod 8 is made of engineering plastic, model ABS, with anti-slip texture on the surface. The connecting shaft 10 welded to the inside of the fixing block 5 is made of stainless steel. The connecting shaft 2 11 welded to one end of the connecting rod 8 is made of the same material as connecting shaft 10. The connecting spring 18, which is sleeved and fixed in the middle of the two, is a cylindrical helical tension spring, model YI-L8-20, made of 60Si2Mn steel. In the locked state, the connecting rod 8 is locked at a 90-degree angle. The advantage of this structure is that, under normal conditions, the connecting spring 18 pulls the connecting rod 8 through the connecting shaft 10 and the connecting shaft 2 11, causing the limiting half gear 7 to mesh with the rotating gear 6, locking the rotation state of the rotating gear 6, thereby fixing the relative position of the assembly column 2 and the support 3, preventing displacement of the assembly structure due to vibration or external force, and ensuring the stability of the assembly. When it is necessary to adjust the position of the assembly column 2, pull the pull handle 9 upward. The connecting rod 8 rotates around the rotating shaft of the limiting half gear 7 and stretches the connecting spring 18, causing the limiting half gear 7 to disengage from the rotating gear 6. After the lock is released, the assembly column 2 can be pushed. The adjustment is achieved by the meshing of the toothed block 4 with the rotating gear 6. After the adjustment is completed, release the handle, and the connecting spring 18 resets, causing the limiting half gear 7 to re-mesh and lock. The operation is convenient and the locking is reliable. The high-precision meshing of the rotating gear 6 and the toothed block 4 ensures a smooth adjustment process and avoids jamming. At the same time, it accurately controls the adjustment accuracy of the assembly column 2 to adapt to different height requirements.

[0027] Reference Figures 1 to 6 A stop block 12 is fixedly installed at one end of the connecting rod 8, and the two ends of the connecting rod 8 are symmetrically fixedly installed on the stop block 12. A stop groove 13 is symmetrically opened at the top of the fixed block 5. The stop block 12 is adapted to the stop groove 13. A limit block 14 is slidably connected inside the stop block 12. A limit groove 15 is opened inside the stop groove 13. The limit block 14 is adapted to the limit groove 15. A damping spring 16 is fixedly installed inside the stop block 12, and one end of the damping spring 16 is fixedly installed to the limit block 14. A pull rod 17 is slidably connected to the top of the stop block 12, and the pull rod 17 is fixedly installed to the top of the limit block 14.

[0028] The above scheme is adopted: the stop block 12 welded to one end of the connecting rod 8 is made of 45# steel. The surface of the stop block 12 is polished to prevent sliding and jamming, and it is symmetrically distributed at both ends of the connecting rod 8. The inner wall of the symmetrically opened stop groove 13 on the top of the fixing block 5 is smooth and precisely matches the size of the stop block 12. The limiting block 14 slidably connected inside the stop block 12 is made of stainless steel. The surface of the limiting block 14 is chrome-plated for rust prevention, and one end is wedge-shaped for easy locking. The limiting groove is opened inside the stop groove 13. The inner wall of the 15 is regular and fits the limit block 14. The damping spring 16 welded and fixed inside the stop block 12 is a cylindrical helical compression spring, model YI-C6-12, made of 60Si2Mn spring steel, with excellent damping characteristics and strong fatigue resistance. One end of the damping spring 16 is welded and fixed to the limit block 14. The pull rod 17 slidably connected to the top of the stop block 12 is made of stainless steel. The top of the pull rod 17 is provided with anti-slip protrusions for easy pulling and is welded and fixed to the top of the limit block 14.

[0029] Reference Figures 1 to 6 The bottom of the monitor body 1 is fixedly installed with an assembly block 19, and the bottom of the assembly block 19 is slidably connected with a sliding rail 20. The outer periphery of the assembly column 2 is symmetrically provided with connecting pipes 21, and the two ends of the fixing plate 23 are symmetrically provided with rotating blocks 24. The middle of the connecting pipe 21 and the rotating block 24 is provided with a rotating rod 22.

[0030] The above-mentioned scheme includes: assembly block 19, sliding track 20, connecting pipe 21, rotating rod 22 and rotating block 24, all of which are prior art referenced in the prior art documents and are not described in detail in this application.

[0031] The working principle of this utility model is as follows: During assembly, the assembly column 2 and the support member 3 are first slidably connected, so that the toothed block 4 at the top of the assembly column 2 and the rotating gear 6 inside the fixing block 5 at the top of the support member 3 are initially engaged, realizing the initial positioning of the assembly column 2 and the support member 3 and avoiding displacement during the connection process. Then, the pull handle 9 is released, and the connecting spring 18 between the connecting shaft 10 and the connecting shaft 2 11 of the connecting rod 8 inside the fixing block 5 releases its elastic potential energy, pulling the connecting rod 8 to rotate, which drives the limiting half gear 7 at one end of the connecting rod 8 to rotate synchronously. When the limiting half gear 7 and the rotating gear 6 are tightly meshed, the rotating gear 6 is locked by the limiting half gear 7 and cannot rotate freely. This, in turn, restricts the axial movement of the assembly column 2 through the tooth block 4, forming the first layer of locking to prevent the assembly column 2 and the support member 3 from sliding relative to each other due to vibration. At the same time, when the connecting rod 8 rotates, it will drive the symmetrically fixed stop blocks 12 at both ends to move synchronously, so that the stop blocks 12 are embedded in the symmetrically opened stop grooves 13 at the top of the fixed block 5. When the stop blocks 12 and the stop grooves 13 coincide, the damping spring 16 inside the stop blocks 12 pushes... The movable limit block 14 slides until it engages with the limit slot 15 inside the stop groove 13, forming a second lock. This further restricts the rotation of the connecting rod 8, preventing the limit half gear 7 from disengaging from the rotating gear 6 due to external force, thus ensuring the stability of the first lock. When maintenance and disassembly are required, first pull the lever 17 at the top of the stop block 12 to compress the damping spring 16, causing the limit block 14 to disengage from the limit slot 15 and releasing the second lock. Then, pull the handle 9 upwards. The moving link 8 overcomes the tension of the connecting spring 18 and rotates around the connecting shaft 10, causing the limiting half gear 7 to disengage from the rotating gear 6 and releasing the first locking. At this time, the rotating gear 6 can rotate freely, pushing or pulling the assembly column 2 so that it slides along the support member 3, thus completing the separation of the assembly column 2 from the support member 3. This facilitates the maintenance of the LCD display module. After maintenance, the double locking can be re-achieved by reversing the steps, ensuring a stable connection between the assembly column 2 and the support member 3 and preventing loosening due to wear or vibration after long-term use.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
