Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and more specifically, to a portable liquid crystal display screen. Background Technology

[0002] The emergence of portable LCD screens stems from people's upgraded demand for "flexible displays." In the past, displays were mostly integrated devices fixed to computers and televisions, unable to be moved independently from the host. However, with the increase in scenarios such as mobile office, outdoor live streaming, and home entertainment, people need displays that can be carried and used quickly at any time. For example, business people want to use their laptops to process documents on a large external screen in hotels when they are on business trips; outdoor bloggers need an extra screen to view comments or scripts when they are live streaming; and parents also want to bring a small screen for their children to play animations on the go.

[0003] In existing technologies, traditional portable displays have fixed screen sizes, making it difficult to meet the needs of displaying multiple contents or viewing on a large screen; the displays lack stable and adjustable support structures, making them prone to tipping over or being placed at an unsuitable angle; portable accessories (such as wrist straps) are cumbersome to install and remove, and the connections are not secure, affecting carrying safety; the extended screen is not reliably fixed after being unfolded, and is prone to displacement due to external forces, causing display interruption.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a portable liquid crystal display screen, which has the following beneficial effects:

[0017] 1. The device expands the display function through the extension screen design: Pressing the limit handle unlocks the extension screen. After flipping it 180 degrees, the limit block automatically snaps into the limit groove under the action of the spring, quickly completing the fixation of the extension screen. The extension screen and the main display screen can work together to achieve a larger display area or split-screen display, which is suitable for multi-tasking (such as office presentations and movie viewing) needs. The unlocking and fixing operations are simple and do not require complicated tools.

[0018] 2. The support structure balances stability and angle flexibility: When the support plate is flipped outward, the connecting plate drives the sliding rod to move along the sliding groove. After adjusting to the appropriate support angle, the sliding rod can be fixed by locking into the limit hole, which prevents angle deviation during the support process, improves placement stability, avoids the display screen from tipping over, and is suitable for various placement scenarios such as desktops and tabletops.

[0019] 3. The wrist strap design greatly enhances portability: When installing the wrist strap, simply move the fixing ring to retract the insertion rod, align the fixing rod with the fixing block, and then release it. The insertion rod will automatically snap into the insertion slot under the action of the spring. At the same time, the fixing ball and the fixing slot cooperate to restrict vertical movement, achieving quick and secure installation of the wrist strap. The same principle applies when disassembling, making it convenient for users to carry the display screen with the wrist strap at any time, preventing it from slipping when held, and making it suitable for outdoor, commuting and other mobile use scenarios.

[0029] Please see Figures 1-5 A portable LCD display includes a display body 1, a back plate 2 on one side of the display body 1, a support groove 3 on the back side of the back plate 2, a support plate 4 hinged to the support groove 3 by a torsion spring, a connecting plate 5 between the support plate 4 and the back plate 2, an extension screen 6 on the back plate 2, a hinge plate 7 on the back plate 2, a hinge shaft 8 on the extension screen 6, a limiting groove 9 and a sliding groove 10 on the hinge shaft 8, a limiting block 11 in the limiting groove 9, and a sliding groove 10 on both sides of the limiting block 11. The sliding block 12 is fitted with the moving groove 10. The hinge plate 7 is provided with a limiting ring groove 13 and a limiting groove 14 that fit with the sliding block 12. A limiting spring 15 is provided between the limiting groove 9 and the limiting block 11. A limiting handle 16 is provided on the top of the limiting block 11. A connecting groove 17 that fits with the connecting plate 5 is provided in the support groove 3. Sliding grooves 18 are provided on both sides of the connecting groove 17. A sliding rod 19 is provided in the sliding groove 18. The sliding rod 19 is hinged to the connecting plate 5. A limiting hole 20 is provided on the sliding groove 10.

[0030] In this embodiment, when the extension screen 6 needs to be opened, the limiting handle 16 is pressed down. The limiting handle 16 presses down the limiting block 11 and the limiting spring 15, causing the sliding block 12 to move downward along the sliding groove 10, so that the sliding block 12 moves downward into the limiting ring groove 13. The extension screen 6 is rotated, and the extension screen 6 drives the hinge shaft 8, the limiting block 11 and the sliding block 12 to rotate. The sliding block 12 rotates along the limiting ring groove 13. When the extension screen 6 is rotated 180 degrees, the sliding block 12 moves to the limiting groove 14. Under the elastic force of the limiting spring 15, the limiting block 11 moves upward and extends into the limiting groove 14, adjusting the position of the sliding block 12 and the limiting block 11. The hinge pin 8 and hinge plate 7 are fixed, and the relative positions of the extension screen 6 are also fixed. The extension screen 6 is used in conjunction with the display screen body 1. When it is necessary to support the display screen body 1, the support plate 4 is flipped outward. The support plate 4 drives the connecting plate 5 to rotate and adjust the support angle. The connecting plate 5 drives the sliding rod 19 to slide against the upper wall of the sliding groove 18. After the support angle is adjusted, the sliding rod 19 is inserted into the limiting hole 20. The limiting hole 20 prevents the sliding rod 19 from moving further, thus completing the support of the display screen body 1. Anti-slip pads can be installed at the bottom of the back plate 2 and the support plate 4 to improve the installation stability.

[0031] Please see Figure 5As one embodiment of the portable display screen body 1: The display screen body 1 is provided with a fixing block 21, a fixing rod 22 and a hand strap 23 on the fixing block 21, a fixing ball 24 on the fixing rod 22, a fixing groove 25 on the fixing block 21 that cooperates with the fixing ball 24, a fixing slide groove 26 on the fixing rod 22, a fixing slide plate 27 that slides within the fixing slide groove 26, an insertion rod 28 on the fixing slide plate 27, an insertion groove 29 on the fixing rod 22 that cooperates with the insertion rod 28, a fixing spring 30 between the fixing slide groove 26 and the fixing slide plate 27, and a fixing ring 31 on the fixing slide plate 27.

[0032] More specifically, by aligning the fixing rod 22 on the hand strap 23 with the fixing block 21, the fixing ring 31 is moved upward. The fixing ring 31 drives the fixing slide plate 27 to move within the fixing groove 26 and compresses the fixing spring 30. The fixing slide plate 27 drives the insertion rod 28 to move upward. The fixing rod 22 drives the fixing rod 22 and the fixing ball 24 to extend into the fixing groove 25, limiting the vertical movement of the fixing rod 22 and the fixing block 21. The fixing ring 31 is released, and the fixing slide plate 27, under the elastic force of the fixing spring 30, drives the insertion rod 28 to extend into the insertion hole, limiting the horizontal movement of the fixing rod 22 and the fixing block 21. This makes it easier to install the hand strap 23 onto the display screen body 1, making the display screen body 1 more portable.

[0033] In summary, during the use or operation of the entire device: when it is necessary to open the extension screen 6, press the limit handle 16. The limit handle 16 presses down the limit block 11 and the limit spring 15, causing the sliding block 12 to move downward along the sliding groove 10, so that the sliding block 12 moves downward into the limit ring groove 13. Rotate the extension screen 6, and the extension screen 6 will drive the hinge shaft 8, the limit block 11, and the sliding block 12 to rotate. The sliding block 12 rotates along the limit ring groove 13. When the extension screen 6 is rotated 180 degrees, the sliding block 12 moves to the limit groove 14. Under the elastic force of the limit spring 15, the limit block 11 moves upward and extends into the limit groove 14, thus controlling the movement of the sliding block 12 and the limit block 11. The position of 1 is fixed, thereby fixing the relative positions of the hinge shaft 8 and the hinge plate 7, and fixing the relative position of the extension screen 6. The extension screen 6 is used in conjunction with the display body 1. When it is necessary to support the display body 1, the support plate 4 is flipped outward. The support plate 4 drives the connecting plate 5 to rotate and adjust the support angle. The connecting plate 5 drives the sliding rod 19 to slide against the upper wall of the sliding groove 18. After the support angle is adjusted, the sliding rod 19 is inserted into the limiting hole 20. The limiting hole 20 prevents the sliding rod 19 from moving further, thereby completing the support of the display body 1. Anti-slip pads can be installed at the bottom of the back plate 2 and the support plate 4 to improve the installation stability.

[0034] Aligning the fixing rod 22 on the hand strap 23 with the fixing block 21, the fixing ring 31 moves upward, causing the fixing plate 27 to move within the fixing groove 26 and compressing the fixing spring 30. The fixing plate 27 then causes the insertion rod 28 to move upward, and the fixing rod 22 and the fixing ball 24 extend into the fixing groove 25, limiting the vertical movement of the fixing rod 22 and the fixing block 21. Releasing the fixing ring 31 allows the fixing plate 27 to extend the insertion rod 28 into the insertion hole under the elastic force of the fixing spring 30, limiting the horizontal movement of the fixing rod 22 and the fixing block 21. This facilitates the installation of the hand strap 23 onto the display screen body 1, making the display screen body 1 more portable.
