Description
Technical Field
[0001] This utility model relates to the field of liquid crystal display module technology, specifically to a liquid crystal display module that is easy to install. Background Technology
[0002] A liquid crystal display module is a complete display assembly that combines liquid crystal display devices, connectors, integrated circuits, control and drive circuits, PCB circuit boards, backlights, and structural components, and can be designed according to user needs.
[0003] A search revealed Chinese patent CN217360762U, which discloses a liquid crystal display touch module for easy and quick installation. This patent relates to the field of liquid crystal display technology and includes a display screen body, a display screen housing, and a touch module body. Connecting components are installed on both sides of the touch module body. Each connecting component includes a connecting block, which is installed on one side of the touch module body and has a slot on one side. A fixing block is installed on one side of the display screen body. In this invention, when the touch module body needs to be quickly installed on the display screen, the two locking blocks are moved away from each other by a rotating rod, sliding sleeve, slider, and push rod. Two springs retract, and the fixing block is then inserted into the slot. Under the spring force, the two locking blocks are inserted into the two slots of the fixing block, thus quickly installing the touch module body on the display screen. Furthermore, it can be installed and removed without tools, making operation convenient and improving the device's usability.
[0004] However, the above design still has shortcomings. In the above design, the spring elasticity drives the locking block to insert into the fixing block, thereby realizing the installation and fixing of the module body. However, in actual use, when the module body malfunctions and needs to be disassembled for maintenance, the deformation degree of the spring will gradually decrease, and the locking block may not be able to detach from the fixing block in the later stage, which is not conducive to the maintenance of the module body.
[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0006] The purpose of this invention is to provide an easy-to-install liquid crystal display module to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a liquid crystal display module that is easy to install, comprising a display screen housing, a display screen body fixedly disposed on the front end face of the display screen housing, a display screen back cover movably mounted on the rear end face of the display screen housing via bolts, a mounting plate fixedly connected to the front end face of the display screen back cover, a mounting groove formed on the front end face of the mounting plate, a mounting block movably disposed inside the mounting groove, a positioning hole formed on the outer wall of the mounting block, a module body fixedly connected to the front end face of the mounting block, and a positioning hole formed on the right outer wall of the mounting plate. A positioning screw hole is provided, and a rotating plate is rotatably provided on the right side of the positioning screw hole. A positioning screw is movably provided through the surface of the rotating plate, and one end of the positioning screw is threaded inside the positioning screw hole. A transmission rod is fixedly connected to the left side of the rotating plate, and a bidirectional screw is fixedly connected to the left side of the transmission rod. A moving block is threadedly connected to the outer wall of the bidirectional screw. A crossbar is movably provided through the surface of the moving block, and a transmission block is fixedly connected to the front end face of the moving block. Positioning rods are fixedly connected to the two transmission blocks on their opposite sides, and one end of the positioning rod is movably provided inside the positioning hole.
[0008] As a further embodiment of this utility model: an air outlet communicating with the interior is provided on the left side of the display screen housing, and an air inlet communicating with the interior is provided on the right side of the display screen housing.
[0009] As a further embodiment of this utility model: a first micro fan is installed on the right side of the air outlet, and a second micro fan is installed on the left side of the air inlet.
[0010] As a further embodiment of this utility model: both ends of the air outlet and the air inlet are provided with limiting grooves, and limiting blocks are movably arranged inside the limiting grooves. An installation cavity is opened on the outer wall of the limiting block, and a dustproof plate is fixedly connected to the side of the two limiting blocks that are far apart from each other.
[0011] As a further embodiment of this utility model: a groove is provided at the ends of two adjacent mounting cavities that are far apart from each other, and a locking block is movably disposed inside the groove.
[0012] As a further embodiment of this utility model: each of the two adjacent card blocks is fixedly connected to a movable plate at one end close to each other, and each of the two adjacent movable plates is fixedly connected to a spring at one end close to each other.
[0013] This utility model has the following beneficial effects:
[0014] The structural design of the display screen housing, display screen back cover, mounting plate, module body, moving block, crossbar, bidirectional screw, transmission block, positioning rod, positioning hole, mounting groove, mounting block, positioning screw hole, transmission rod, positioning screw, and rotating plate facilitates easy assembly and disassembly of the module body. The operation is simple and efficient. After the module body is installed, one end of the positioning screw passes through the rotating plate and is screwed into the positioning screw hole to fix the rotating plate and prevent it from rotating, thus improving the stability of the module body after installation. This solves the problem of using a spring to drive a locking block into a fixing block for module body installation and fixation. However, in actual use, when the module body malfunctions and needs to be disassembled for repair, the spring's deformation gradually decreases, and the locking block may eventually fail to detach from the fixing block, hindering module body repair.
[0015] Through the structural design of dustproof plates, air outlets, a first micro fan, an air inlet, a second micro fan, grooves, locking blocks, limiting grooves, limiting blocks, mounting cavities, movable plates, and springs, the high-heat gas inside the display screen casing can be rapidly exchanged with the cooler outside air, thereby achieving rapid heat dissipation. At the same time, during the heat dissipation process, the two dustproof plates can prevent external dust from entering the interior of the display screen casing with the airflow, and can be easily disassembled and cleaned, effectively ensuring its filtration effect.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] Please see Figure 1-5 This utility model provides an embodiment of an easy-to-install liquid crystal display module, comprising a display screen housing 1, a display screen body 4 fixedly mounted on the front end face of the display screen housing 1, a display screen back cover 3 movably mounted on the rear end face of the display screen housing 1 via bolts, a mounting plate 5 fixedly connected to the front end face of the display screen back cover 3, a mounting groove 17 formed on the front end face of the mounting plate 5, a mounting block 18 movably mounted inside the mounting groove 17, a positioning hole 16 formed on the outer wall of the mounting block 18, a module body 10 fixedly connected to the front end face of the mounting block 18, and a positioning screw hole 19 formed on the right outer wall of the mounting plate 5. A rotating plate 22 is rotatably provided on the right side of the rotating plate 22. A positioning screw 21 is movably provided through the surface of the rotating plate 22, and one end of the positioning screw 21 is threaded inside the positioning screw hole 19. A transmission rod 20 is fixedly connected to the left side of the rotating plate 22. A bidirectional screw 13 is fixedly connected to the left side of the transmission rod 20. A moving block 11 is threadedly connected to the outer wall of the bidirectional screw 13. A crossbar 12 is movably provided through the surface of the moving block 11. A transmission block 14 is fixedly connected to the front end face of the moving block 11. A positioning rod 15 is fixedly connected to the side of the two transmission blocks 14 that are far apart from each other, and one end of the positioning rod 15 is movably provided inside the positioning hole 16.
[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during use, when it is necessary to install the module body 10, the mounting block 18 at the rear end of the module body 10 is inserted into the mounting slot 17. Then, the rotating plate 22 is rotated. The rotation of the rotating plate 22 drives the transmission rod 20 to rotate. The rotation of the transmission rod 20 drives the bidirectional screw 13 to rotate. The rotation of the bidirectional screw 13 drives the two moving blocks 11 to move in a direction away from each other. The movement of the moving blocks 11 drives the transmission block 14 to move. The movement of the transmission block 14 drives the positioning rod 15 to move towards the positioning hole 16 until one end of the positioning rod 15 is inserted into the positioning hole 16, thereby completing the fixing of the mounting block 18 and thus completing the installation of the module body 10. Similarly, the module body 10 can be installed. The disassembly of module 10 is simple and efficient. After the module body 10 is installed, one end of the positioning screw 21 is passed through the rotating plate 22 and screwed into the positioning screw hole 19 to fix the rotating plate 22 and prevent it from rotating, thereby improving the stability of the module body 10 after installation. This solves the problem that when the module body 10 is disassembled and repaired due to a failure, the deformation degree of the spring 29 will gradually decrease, and the locking block 24 may not be able to detach from the fixing block in the later stage, which is not conducive to the repair of the module body 10.
[0029] The left side of the display screen housing 1 is provided with an air outlet 6 that communicates with the interior, and the right side of the display screen housing 1 is provided with an air inlet 8 that communicates with the interior. A first micro fan 7 is installed on the right side of the air outlet 6, and a second micro fan 9 is installed on the left side of the air inlet 8. Limiting grooves 25 are provided at both ends of the air outlet 6 and the air inlet 8. Limiting blocks 26 are movably arranged inside the limiting grooves 25. Mounting cavities 27 are provided on the outer walls of the limiting blocks 26. Dustproof plates 2 are fixedly connected to the sides of the two limiting blocks 26 that are far apart from each other. Grooves 23 are provided at the ends of the two adjacent mounting cavities 27 that are far apart from each other. Locking blocks 24 are movably arranged inside the grooves 23. Movable plates 28 are fixedly connected to the ends of the two adjacent locking blocks 24 that are close to each other. Springs 29 are fixedly connected to the ends of the two adjacent movable plates 28 that are close to each other.
[0030] Specifically, such as Figure 1 , Figure 2 and Figure 5As shown, during use, the airflow generated by the rotation of the second micro fan 9 draws cooler outside air into the display screen housing 1 through the air inlet 8, while the airflow generated by the rotation of the first micro fan 7 blows the hot air inside the display screen housing 1 out through the air outlet 6. This achieves rapid exchange between the hot air inside the display screen housing 1 and the cooler outside air, thus achieving rapid heat dissipation. Simultaneously, during heat dissipation, the two dustproof plates 2 prevent external dust from entering the display screen housing 1 with the airflow. After a period of use, pressing the locking block 24 moves it into the mounting cavity 27. Once the locking block 24 is in the appropriate position, the dustproof plate 2 moves outward until the limiting block 26 disengages from the limiting groove 25, thus completing the removal of the dustproof plate 2. Similarly, the dustproof plate 2 can be installed. The ease of disassembling and cleaning the dustproof plate 2 effectively ensures its filtration effect.
[0031] Working principle: In this application, when the module body 10 needs to be installed, the mounting block 18 at the rear end of the module body 10 is inserted into the mounting slot 17. Then, the rotating plate 22 is rotated, which drives the transmission rod 20 to rotate. The transmission rod 20 drives the bidirectional screw 13 to rotate. The bidirectional screw 13 drives the two moving blocks 11 to move in a direction away from each other. The movement of the moving blocks 11 drives the transmission block 14 to move. The movement of the transmission block 14 drives the positioning rod 15 to move towards the positioning hole 16 until one end of the positioning rod 15 is inserted into the positioning hole 16, thereby completing the fixing of the mounting block 18 and thus completing the installation of the module body 10. Similarly, the module body 10 can be disassembled. The operation is simple and the disassembly and assembly efficiency is high. In addition, the wind force generated by the rotation of the second micro fan 9 can draw in cooler outside air through the air inlet 8. Inside the display casing 1, the high-heat gas inside the display casing 1 can be blown out of the casing through the air outlet 6 by the wind force generated when the first micro fan 7 rotates. This achieves rapid exchange between the high-heat gas inside the display casing 1 and the cooler outside air, thereby achieving rapid heat dissipation. Finally, during the heat dissipation process, the two dustproof plates 2 prevent external dust from entering the interior of the display casing 1 with the airflow. After a period of use, the locking block 24 can be pressed to move into the mounting cavity 27. When the locking block 24 moves to the appropriate position, the dustproof plate 2 moves along the outside until the limiting block 26 disengages from the limiting groove 25, thereby completing the disassembly of the dustproof plate 2. Similarly, the dustproof plate 2 can be installed. By facilitating the disassembly and cleaning of the dustproof plate 2, its filtration effect can be effectively guaranteed.
