Description

Technical Field

[0001] This utility model belongs to the technical field of ruggedized ultra-thin mobile phone LCD displays, and particularly relates to a ruggedized ultra-thin mobile phone LCD display. Background Technology

[0002] A liquid crystal display (LCD) is a display device that uses liquid crystal materials and specific technologies. By controlling the arrangement of liquid crystal molecules, it changes light transmittance and color, thereby presenting clear images and text. It has advantages such as low power consumption, small size, light weight, high display quality, and no radiation, and is widely used in various electronic devices such as televisions, computers, mobile phones, and tablets.

[0003] For example, Chinese patent CN222421268U discloses a reinforced ultra-thin mobile phone LCD display, including a back panel, a display body, and a clamping frame. The top of the back panel has a placement slot and a connecting slot. A rectangular array of fixing components is arranged inside the back panel, each including a sliding groove inside the back panel that communicates with the connecting slot. Springs are fixedly installed on opposite sides of the inner wall of each sliding groove, and a fixing plate is slidably connected inside each groove. The other ends of the two springs are fixedly connected to the fixing plate. A rectangular array of inner slots is formed on the outer wall of the clamping frame, and the fixing plate engages with these inner slots. This invention, by setting up fixing components, can fix the display body in the event of a collision, preventing the display body from shaking inside the placement slot, effectively preventing secondary damage to the internal display body, and improving the lifespan of the display body.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use, such as: when the tempered glass is accidentally broken, the entire clamping frame needs to be replaced, which is quite troublesome. Furthermore, disassembling the clamping frame requires personnel to use tools to unscrew eight screws, which is inconvenient, and the screws are prone to being lost. Therefore, we propose a reinforced ultra-thin mobile phone LCD display. Utility Model Content

[0006] The purpose of this invention is to provide a reinforced ultra-thin mobile phone LCD screen to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a ruggedized ultra-thin mobile phone LCD screen, comprising:

[0008] The back panel has a mounting groove at its top. A buffer pad is fixedly installed on the inner wall of the mounting groove. The display body is located inside the buffer pad. A cover plate is inserted and installed in the mounting groove and at the top of the display body. A insertion groove is opened in the cover plate. A sealing gasket is fixedly installed at the top of the insertion groove. A glass plate is inserted and installed in the insertion groove.

[0009] Two grooves are provided, both of which are located inside the back panel and on both sides of the display body. A sliding plate is slidably installed in each groove. Several springs fixed to the bottom of the sliding plate are fixedly installed at the bottom of the groove. A pressing block is fixedly installed at the bottom of the cover plate and in each of the two grooves.

[0010] A fixing component, located within the back panel, is used to fix the cover plate.

[0011] In this technical solution, when the glass plate is accidentally broken, personnel can release the cover plate from its limiting position using the fixing component. At this time, under the rebound force of several springs, the springs will press the two sliding plates upwards respectively. The upward movement of the two sliding plates will press the two downward pressure blocks respectively, allowing the cover plate to be removed from the mounting groove. This ensures that personnel can easily remove the cover plate. Subsequently, personnel can pull the glass plate on the cover plate out of the insertion groove and replace it. With the sealing effect of the sealing gasket, water cannot enter the gap between the glass plate and the insertion groove. After replacement, the cover plate is inserted back into the mounting groove. At this time, the fixing component can fix the cover plate, ensuring that personnel can easily replace it when the glass plate is broken. At the same time, when fixing the cover plate, multiple screws are not required, which is more convenient and prevents the loss of screws.

[0012] In the above technical solution, the fixing component further includes:

[0013] The second sliding groove is formed inside the back plate and located on one side of the cover plate. The second limiting block is slidably installed inside the second sliding groove. One end of the second limiting block passes through one side of the second sliding groove and extends into the cover plate. The other end of the second limiting block and located inside the second sliding groove is fixedly installed with a pull rod. One end of the second pull rod passes through the other side of the second sliding groove and is fixedly installed with a pull plate. The other end of the second limiting block is fixedly installed with several springs three that are fixed to the inner wall of the second sliding groove.

[0014] Two sliding grooves are provided, both of which are located inside the back plate and on the other side of the cover plate. A limiting block is slidably installed inside each sliding groove. One end of the limiting block extends through one side of the sliding groove and into the cover plate. A pull rod is fixedly installed at the other end of the limiting block and inside the sliding groove. One end of the pull rod extends through the other side of the sliding groove and is fixedly installed with a pull plate. Several springs are fixed to the inner wall of the sliding groove at the other end of the limiting block.

[0015] In this technical solution, when the glass plate is accidentally broken, a person can use a plastic pry bar to insert into the bottom of the second pull plate and pry it up. Then, pull the second pull plate. The movement of the second pull plate will cause the second pull rod to move, which in turn will cause the second limit block to move. The movement of the second limit block will compress several third springs to retract until one end of the second limit block moves out of the cover plate. At this point, the second limit block can release the cover plate from its restriction. Then, the plastic pry bar is inserted into the bottom of the two first pull plates and pryed up. The movement of the first pull plate will cause the first pull rod to move, which in turn will cause the first limit block to move. The movement of the first limit block will compress several second springs to retract until one end of the two first limit blocks moves out of the cover plate. At this point, the two first limit blocks can release the cover plate from its restriction, and the glass plate on the cover plate can be pulled out of the insertion slot and replaced.

[0016] In the above technical solution, one end of the limiting block two is inserted into the cover plate, and one end of the limiting block two has an inclined structure. The pull rod two is slidably connected to the sliding groove two and the back plate. One end of the limiting block one is inserted into the cover plate, and one end of the limiting block one has an inclined structure. The pull rod one is slidably connected to the sliding groove one and the back plate. The bottoms of the pull plate one and the pull plate two are both inclined.

[0017] In this technical solution, it is ensured that one end of the limiting block 2 can be inserted into the cover plate, that the downward movement of the cover plate can squeeze the limiting block 2 to move, that the pull rod 2 can slide normally in the sliding groove 2 and the back plate, that one end of the limiting block 1 can be inserted into the cover plate, that the downward movement of the cover plate will squeeze the limiting block 1 to move, that the pull rod 1 can slide normally in the sliding groove 1 and the back plate, and that the plastic pry bar can be inserted into the bottom of the pull plate 1 and the pull plate 2.

[0018] In the above technical solution, the pressing block is further engaged with the groove, and the bottom of the pressing block abuts against the top of the sliding plate.

[0019] In this technical solution, it is ensured that the lower pressure block can be inserted into the groove, and that the upward movement of the sliding plate can compress the lower pressure block to move upward.

[0020] In the above technical solution, further, the periphery of the display body is in close contact with the inner wall of the buffer pad, and the glass plate is in close contact with the bottom of the sealing gasket.

[0021] In this technical solution, the buffer pad is designed to cushion the display body, ensuring a tight seal between the glass plate and the connector slot.

[0022] In the above technical solution, the cover plate and the two pressing blocks are integrally formed.

[0023] In this technical solution, the structural stability of the cover plate and the two lower pressure blocks is ensured.

[0024] In the above technical solution, the top of the cover plate and the top of the back plate are located on the same horizontal plane.

[0025] In this technical solution, the aesthetics of the cover plate after installation are ensured.

[0026] The beneficial effects of this utility model are:

[0027] This ruggedized ultra-thin mobile phone LCD screen, through its set fixing components, including the glass plate, cover plate, spring, sliding plate, pressure block, mounting groove, and sealing gasket, ensures that the glass plate can be easily replaced if it breaks. Furthermore, fixing the cover plate requires no multiple screws, making it convenient and preventing screw loss. The cushioning pad also cushions the display body, preventing it from shaking and protecting it from damage. Attached Figure Description

A pressing block 7 is fixedly installed at the bottom of the cover plate 5 and in the two grooves 6 respectively.

[0049] A fixing component is located inside the back plate 1 and is used to fix the cover plate 5.

[0050] When the glass plate 12 is accidentally broken, the cover plate 5 can be released from its limit by the fixing component. At this time, under the rebound force of several springs 9, the springs 9 will press the two sliding plates 8 upward. The upward movement of the two sliding plates 8 will press the two pressing blocks 7, allowing the cover plate 5 to be removed from the mounting groove 2. This ensures that the cover plate 5 can be easily removed by the personnel. Then, the personnel can pull the glass plate 12 on the cover plate 5 out of the insertion groove 10 and replace it.

At this time, the fixing component can fix the cover plate 5, ensuring that it can be easily replaced when the glass plate 12 is broken. At the same time, when fixing the cover plate 5, multiple screws are not required, which is more convenient and prevents the loss of screws.

[0051] Example 2:

[0052] This embodiment provides a ruggedized ultra-thin mobile phone LCD display screen, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a fixing component:

[0053] Sliding groove 2 18 is formed inside the back plate 1 and located on one side of the cover plate 5. Limiting block 2 19 is slidably installed inside sliding groove 2 18.

[0070] Among these measures, it is important to ensure the aesthetic appeal of cover plate 5 after installation.

[0071] It is worth noting that the structure and principle of the display body 4 in this embodiment are all existing technologies. For details, please refer to the prior art publication number CN222421268U, which is entitled "A Reinforced Ultra-thin Mobile Phone LCD Display". It will not be described again here.

[0072] Working principle: When glass plate 12 is accidentally broken, a person can use a plastic pry bar to insert into the bottom of pull plate 21 and pry it up. Pulling pull plate 21 will cause it to move, which in turn will move pull rod 20. Pull rod 20 will then move limit block 19, which will compress several springs 22 until one end of limit block 19 moves out of the cover plate 5. At this point, limit block 19 can release its restriction on cover plate 5. Then, a plastic pry bar can be inserted into the bottom of each of the two pull plates 17 and pry them up. The movement of pull plates 17 will then move pull rod 16, pulling... Moving rod 16 will cause limiting block 14 to move. The movement of limiting block 14 will compress several springs 15, causing them to retract until one end of the two limiting blocks 14 moves out of the cover plate 5. At this time, the two limiting blocks 14 can release the cover plate 5 from its restriction. Then, under the rebound force of several springs 9, the springs 9 will respectively compress the two sliding plates 8 to move upward. The upward movement of the two sliding plates 8 will respectively compress the two pressing blocks 7, allowing the cover plate 5 to be removed from the mounting groove 2, ensuring that the cover plate 5 can be easily removed by personnel. Then, personnel can pull out the glass plate 12 on the cover plate 5 from the insertion groove 10 and replace it. The sealing gasket 11 provides a sealing effect. This ensures that water will not enter the gap between the glass plate 12 and the insertion slot 10. After replacement, the cover plate 5 is inserted into the installation slot 2. At this time, the two pressing blocks 7 at the bottom of the cover plate 5 will be inserted into the two grooves 6 respectively and press the sliding plate 8 to move downward. The downward movement of the sliding plate 8 will compress several springs 9 to retract. At the same time, the downward movement of the cover plate 5 will also compress one end of the limiting block 19 and one end of the two limiting blocks 14, so that the limiting block 19 moves in the sliding groove 18 and compresses several springs 22 to retract. The limiting block 14 will move in the sliding groove 13 and compress several springs 15 to retract. When the cover plate 5 is fully inserted... When the glass plate 12 is inserted into the mounting slot 2, under the action of the rebound force of several springs 22, the springs 22 will press the limiting block 19, so that one end of the limiting block 19 is inserted into the cover plate 5. At the same time, under the action of the rebound force of several springs 15, the springs 15 will press the two limiting blocks 14 respectively, so that one end of the two limiting blocks 14 is inserted into the cover plate 5. Under the limiting action of the limiting block 19 and the two limiting blocks 14, the cover plate 5 can be fixed, ensuring that it can be easily replaced when the glass plate 12 is broken. At the same time, when fixing the cover plate 5, multiple screws are not required, which is more convenient and prevents the loss of screws.
