Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display module technology, and in particular to a waterproof liquid crystal display module. Background Technology

[0002] With the continuous updating of science and technology, my country's electronic technology is developing faster and faster. LCD modules are mainly used in mobile phones, televisions, computers and other devices. Their functionality has attracted much attention. As the most critical component of LCD displays, LCD modules play an irreplaceable role. As the demand for LCD modules increases, the requirements for LCD modules are also getting higher and higher.

[0003] Existing waterproof LCD display modules mostly rely on sealing strips for waterproofing. These sealing strips fill the gaps between the module's components, forming a barrier against moisture and liquid, thus ensuring the normal operation of the internal electronic components and preventing problems such as short circuits and corrosion caused by water ingress.

[0004] However, the sealing strips will gradually age due to various factors during use. When the sealing strips show signs of aging or damage and need to be replaced, the entire replacement process is not only time-consuming but also cannot be completed quickly, since most LCD modules are fixed with bolts. This affects the maintenance efficiency and normal use of LCD modules to some extent. Utility Model Content

[0005] For existing waterproof LCD display modules, when the sealing strips show signs of aging or damage and need to be replaced, the replacement process is time-consuming and cannot be completed quickly because LCD display modules are mostly fixed with bolts.

[0006] The technical solution of this utility model is as follows: a waterproof liquid crystal display module, including a housing; further including a back cover and a liquid crystal display screen fixing assembly; a glass screen is provided inside the housing, a liquid crystal display screen body is provided inside the housing, a liquid crystal display screen fixing assembly is provided inside the housing, a back cover is provided on one side of the housing, an insert plate is fixedly connected to one side of the back cover, a sealing strip for waterproofing is provided on one side of the back cover, a pull rod is slidably connected inside the housing, a movable block is fixedly connected to one side of the pull rod, a spring is provided on one side of the movable block, a slider is movably connected inside the housing, a locking block is provided on one side of the slider, a connecting plate is provided on one side of the pull rod, and a handle is provided on one side of the connecting plate.

[0007] Preferably, there are two sets of pull rods, which are symmetrically arranged on the inside of the housing.

[0008] Preferably, the insert plate is provided with a slot one, and the locking block is engaged with the inside of the insert plate through slot three.

[0009] Preferably, the LCD screen fixing assembly includes a mounting plate, a mounting plate is provided on one side of the LCD screen body, a fixing plate is provided on the inner side of the housing, a limit block is fixedly connected to one side of the fixing plate, a first fixing block is provided on one side of the fixing plate, a pressure plate is rotatably connected to the inner side of the first fixing block, a second fixing block is fixedly connected to one side of the fixing plate, a pull plate is provided on one side of the second fixing block, a tension spring is provided between the pull plate and the second fixing block, and a limit pin is fixedly connected to one side of the pull plate.

[0010] Preferably, the mounting plate has a second slot, and the limiting block is engaged and connected to the mounting plate through the second slot.

[0011] Preferably, the pressure plate has a groove three, and the limiting pin is engaged with the inner side of the pressure plate through the groove three.

[0012] Preferably, the second fixing block has a groove four, and the limiting pin is slidably connected to the inside of the second fixing block through the groove four.

[0013] The beneficial effects of this utility model are as follows: Compared with traditional waterproof LCD display modules, when the sealing strip ages or is damaged and needs to be replaced, the replacement process is time-consuming and cannot be completed quickly because LCD display modules are mostly fixed with bolts. This device, by pulling the handle, moves the connecting plate, which in turn moves the pull rod, which in turn moves the movable block. The movable block compresses the spring, causing it to detach from the slider surface and release the slider's limiting fixation. Then, by pulling the back cover, the back cover moves the insert plate, which presses against the locking block. Since one side of the locking block is arc-shaped, the insert plate presses against the locking block, causing it to slide. The locking block slides out of the groove on the insert plate, allowing the back cover to be removed. The sealing strip on the back cover can then be replaced quickly, thus improving replacement efficiency. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-6This utility model provides an embodiment: a waterproof liquid crystal display module, including a housing 1; it also includes a back cover 401 and a liquid crystal display screen fixing assembly; a glass screen 2 is disposed inside the housing 1, a liquid crystal display screen body 3 is disposed inside the housing 1, a liquid crystal display screen fixing assembly is disposed inside the housing 1, a back cover 401 is disposed on one side of the housing 1, an insert plate 402 is fixedly connected to one side of the back cover 401, a sealing strip 403 for waterproofing is disposed on one side of the back cover 401, a pull rod 404 is slidably connected inside the housing 1, a movable block 405 is fixedly connected to one side of the pull rod 404, and the movable block 405... A spring 406 is provided on the side, and a slider 407 is movably connected to the inside of the outer casing 1. A locking block 408 is provided on one side of the slider 407, and a connecting plate 409 is provided on one side of the pull rod 404. A handle 410 is provided on one side of the connecting plate 409. Two sets of pull rods 404 are provided, and the two sets of pull rods 404 are symmetrically arranged on the inside of the outer casing 1. By pulling the connecting plate 409, the two sets of pull rods 404 are moved. A slot 1 is provided on the insert plate 402, and the locking block 408 is engaged with the inside of the insert plate 402 through the slot 3. The slot 1 on the insert plate 402 allows the locking block 408 to engage inside the insert plate 402. To limit the locking block 408, the handle 410 is pulled, causing the connecting plate 409 to move. The connecting plate 409 then moves the pull rod 404, which in turn moves the movable block 405. The movable block 405 compresses the spring 406, causing it to disengage from the surface of the slider 407, thus releasing the locking mechanism on the slider 407. Then, the rear cover 401 is pulled, causing the insert plate 402 to move. The insert plate 402 presses against the locking block 408. Since one side of the locking block 408 is curved, the insert plate 402 presses against the locking block 408, causing it to slide. 408 slides out of the slot on the insert plate 402, thereby removing the back cover 401. Then, the sealing strip 403 on the back cover 401 is replaced, thus quickly replacing the sealing strip 403. After replacement, the insert plate 402 is inserted into one side of the outer shell 1. When the insert plate 402 is installed in place, the handle 410 is released, and the spring 406 loses pressure and slides. The spring 406 compresses the slider 407, causing the slider 407 to slide inside the outer shell 1. The slider 407 drives the locking block 408 to move, so that the locking block 408 engages with the slot on the insert plate 402, thereby completing the fixation.

[0023] Please see Figures 5-6In this embodiment, the liquid crystal display screen fixing assembly includes a mounting plate 501. The mounting plate 501 is located on one side of the liquid crystal display screen body 3, and a fixing plate 502 is located inside the outer casing 1. A limiting block 503 is fixedly connected to one side of the fixing plate 502, and a first fixing block 504 is located on one side of the fixing plate 502. A pressure plate 505 is rotatably connected to the inner side of the first fixing block 504. A second fixing block 506 is fixedly connected to one side of the fixing plate 502, and a pull plate 508 is located on one side of the second fixing block 506. A tension spring 507 is provided between the pull plate 508 and the second fixing block 506. A limiting pin 509 is fixedly connected to one side of the pull plate 508. A second groove is provided on the mounting plate 501, and the limiting block 503 is engaged with the mounting plate 501 through the second groove. Inside the mounting plate 501, a second groove is provided on the mounting plate 501, which allows the limiting block 503 to engage inside the mounting plate 501, thereby limiting and fixing the mounting plate 501. A third groove is provided on the pressure plate 505, and a limiting pin 509 is engaged inside the pressure plate 505 through the third groove. The limiting pin 509 is engaged inside the pressure plate 505 through the third groove, thereby limiting and fixing the pressure plate 505. A fourth groove is provided on the second fixing block 506, and the limiting pin 509 is slidably connected inside the second fixing block 506 through the fourth groove. The limiting pin 509 slides inside the second fixing block 506 through the fourth groove, thereby guiding and limiting the limiting pin 509.

[0024] During operation, pulling the handle 410 moves the connecting plate 409, which in turn moves the pull rod 404. The pull rod 404 then moves the movable block 405, which compresses the spring 406, causing the movable block 405 to detach from the surface of the slider 407 and releasing its limiting and fixing function. Then, pulling the rear cover 401 moves the insert plate 402, which presses against the locking block 408. Because one side of the locking block 408 is curved, it inserts... Plate 402 presses against block 408, causing block 408 to slide. Block 408 slides out of the groove on plate 402, thereby removing the back cover 401. Then, the sealing strip 403 on the back cover 401 is replaced, allowing for quick replacement of the sealing strip 403. After replacement, plate 402 is inserted into one side of the outer casing 1. When plate 402 is in place, handle 410 is released, causing spring 406 to lose pressure and slide. Spring 406 compresses slider 407, causing slider 407 to slide. 7. Sliding within the outer casing 1, the slider 407 moves the locking block 408, causing the locking block 408 to engage with the slot on the insert plate 402, thus completing the fixation. When disassembling the LCD screen body 3, by pulling the pull plate 508, the pull plate 508 drives the limiting pin 509 to slide, and the pull plate 508 stretches the tension spring 507, causing the limiting pin 509 to disengage from the slot on the pressure plate 505, releasing the fixation of the pressure plate 505. Then, the pressure plate 505 is turned, causing the pressure plate 505 to rotate, releasing the fixation of the mounting plate 501, thereby pulling... The LCD screen body 3 drives the mounting plate 501 to disengage from the limiting block 503, thereby removing the LCD screen body 3. During installation, the mounting plate 501 is engaged with the outside of the limiting block 503, and then the pressure plate 505 is pulled to rotate, pressing the pressure plate 505 onto the mounting plate 501. Then the pull plate 508 is released, and the tension spring 507 pulls the pull plate 508 to move. The pull plate 508 drives the limiting pin 509 to move, so that the limiting pin 509 is engaged with the inner side of the groove three on the pressure plate 505, thereby completing the fixation.

[0025] Through the above steps, by pulling the handle 410, the handle 410 moves the connecting plate 409, the connecting plate 409 moves the pull rod 404, the pull rod 404 moves the movable block 405, and the movable block 405 compresses the spring 406, causing the movable block 405 to disengage from the surface of the slider 407, thus releasing the limiting and fixing of the slider 407. Then, by pulling the rear cover 401, the rear cover 401 moves the insert plate 402, and the insert plate 402 compresses the locking block 408. Since one side of the locking block 408 is arc-shaped, the insert plate 402 compresses the locking block 408, causing the locking block 408 to slide. 8. Slide the insert plate 402 out of the slot 1 to remove the back cover 401. Then replace the sealing strip 403 on the back cover 401 to quickly replace the sealing strip 403. After replacement, insert the insert plate 402 into one side of the outer shell 1. When the insert plate 402 is in place, release the handle 410. The spring 406 loses pressure and slides. The spring 406 presses the slider 407, causing the slider 407 to slide inside the outer shell 1. The slider 407 drives the locking block 408 to move, so that the locking block 408 engages with the slot 1 on the insert plate 402, thereby completing the fixation.
