Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, specifically a drop-resistant liquid crystal electronic display screen. Background Technology

[0002] LCD electronic displays are flat panel displays, commonly used in digital clocks, portable computers, mobile phones, etc., which can meet people's visual needs on different devices. However, during the use of the display, especially those that are not easy to carry, they are prone to tipping over due to collisions, causing the display to fall to the ground and break.

[0003] For example, patent CN221354685U discloses a drop-proof LCD screen mold, including an LCD screen. By fixing irregularly shaped blocks at the corners of the side shell and fixing buffers on their outer surfaces, the damage caused by impacts to the LCD screen can be effectively reduced. The irregularly shaped blocks can withstand stronger impact forces, and the buffers further reduce the impact effect, improve the impact resistance of the LCD screen, extend its service life, and protect the integrity and aesthetics of the screen. In the above case, when protecting the electronic display screen, only the four corners of the electronic display screen are protected. However, when the electronic display screen is in use, due to the complex ground conditions, there may be sharp objects placed on the ground, such as toys. When the sides of the electronic display screen come into contact with these sharp objects, the protection of the four corners is difficult to effectively protect the side frame of the display screen, and there is still a risk of the display screen breaking.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing drop-resistant LCD displays. Utility Model Content

[0005] The purpose of this utility model is to provide a drop-resistant liquid crystal electronic display screen to solve the problem mentioned in the background art that, due to the complex ground conditions, there may be sharp objects placed on the ground, such as toys, and when the sides of the electronic display screen come into contact with these sharp objects, the protection of the four corners is insufficient to effectively protect the side frame of the display screen, and there is still a risk of the display screen breaking.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drop-resistant liquid crystal electronic display screen, comprising a display screen body, a buffer pad movably abutting against the outer wall of the display screen body, and a protective frame fixedly connected to the outer wall of the buffer pad; buffer strips movably abutting against both ends of one side of the protective frame, sliding grooves being provided on both sides of the protective frame, and a secondary support frame being slidably connected inside the sliding grooves; and a fixing mechanism for fixing the buffer strips being provided inside the protective frame.

[0007] Furthermore, the fixing mechanism includes a pressing column, which is slidably connected to the top of the protective frame. A U-shaped plate is slidably connected inside the protective frame, and a first spring is installed at the bottom of the U-shaped plate. The bottom end of the first spring is installed inside the protective frame.

[0008] Furthermore, each end of the U-shaped plate is equipped with a locking block, and each end of one side of the two buffer strips is provided with a locking groove. The locking block is slidably connected to the inside of the locking groove. A second spring is installed at the bottom of both sides of the U-shaped plate, and the bottom of the second spring is installed inside the protective frame.

[0009] Furthermore, the protective frame is provided with a locking mechanism for locking the secondary support frame. The locking mechanism includes a rotating column, which is slidably connected to both sides of the protective frame and fixedly connected to the top of the secondary support frame. A sliding block is installed on the outer wall of one side of the rotating column. A sliding groove is opened inside the protective frame, and the sliding block is slidably connected to the inside of the sliding groove. A threaded rod is installed inside the sliding block, and threaded grooves matching the threaded rod are provided on both sides of the protective frame.

[0010] Furthermore, the secondary support frame has movable slots on both sides, and a connecting rod is slidably connected inside the movable slot via a movable block. One end of the connecting rod is rotatably connected to the inside of the protective frame.

[0011] Furthermore, a support leg is rotatably connected to one side of the secondary support frame, and a third spring is installed at one end of the support leg, with one end of the third spring installed inside the secondary support frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This drop-resistant LCD screen effectively protects the screen body from direct contact with the ground through a protective frame, preventing damage. Furthermore, the buffer strips on both ends of one side of the protective frame further enhance the cushioning performance, effectively protecting the delicate electronic components and LCD panel inside the screen and extending its service life.

[0014] Furthermore, by utilizing the cooperation of the pressing column, U-shaped plate, first spring, second spring, and locking block, the buffer strip can be quickly fixed and disassembled. When fixing, pressing the pressing column causes the U-shaped plate to move downward, which in turn moves the locking block downward. After the buffer strip is placed and aligned with the slot, the pressing column is released, and the spring returns to its original position, allowing the locking block to engage with the slot. When disassembling, pressing the pressing column again allows the locking block to slide out of the slot. No complicated tools or operating procedures are required, making it convenient for users to replace or maintain the buffer strip at any time according to actual needs, thus improving the maintainability and flexibility of the product.

[0015] Furthermore, an additional support mechanism is added to the basic LCD screen bracket to support both sides of the screen. When support is needed, the secondary support frame is slid down, and the connecting rod pushes the secondary support frame to rotate to a suitable angle, and then it is locked with a threaded rod. At the same time, the support leg on one side of the secondary support frame unfolds and contacts the support surface under the action of the third spring, which enhances the stability of the support. When the secondary support frame is not needed, it can be easily retracted by reversing the operation, without taking up extra space, so that the screen can be placed stably in different environments, improving the user experience.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides the following technical solution: a drop-resistant liquid crystal electronic display screen, including a display screen body 1, a buffer pad 2 movably abutting against the outer wall of the display screen body 1, and a protective frame 3 fixedly connected to the outer wall of the buffer pad 2; buffer strips 4 movably abutting against both ends of one side of the protective frame 3, and sliding grooves 18 are provided on both sides of the protective frame 3, with a secondary support frame 5 slidably connected inside the sliding grooves 18; a fixing mechanism for fixing the buffer strips 4 is provided inside the protective frame 3; the fixing mechanism includes a pressing post 6, which is slidably connected to the top of the protective frame 3, and a U-shaped plate 8 is slidably connected inside the protective frame 3, with a first spring 7 installed at the bottom of the U-shaped plate 8, and the bottom end of the first spring 7 is installed inside the protective frame 3; a locking block 9 is installed at both ends of both sides of the U-shaped plate 8, and a locking groove is provided at both ends of one side of the two buffer strips 4, with the locking block 9 slidably connected inside the locking groove; a second spring 10 is installed at the bottom of both sides of the U-shaped plate 8, and the bottom of the second spring 10 is installed inside the protective frame 3.

[0026] During use, the protective frame 3 effectively protects the four sides of the display screen body 1, such as... Figure 1 and Figure 2 As shown, buffer strips 4 are movably abutted against both ends of one side of the protective frame 3. The buffer strips 4 enhance the buffering performance of the protective frame 3, preventing the display body 1 from directly contacting the ground in the event of an accidental drop. Figure 3 and Figure 4 As shown, when it is necessary to fix the buffer strip 4, first place the buffer strip 4 against both ends of one side of the protective frame 3, and then press the pressing post 6, as shown. Figure 3 and Figure 4 As shown, because a U-shaped plate 8 is slidably connected inside the protective frame 3, and a first spring 7 is installed at the bottom of the U-shaped plate 8, when the pressing post 6 is pressed, the bottom end of the pressing post 6 will squeeze the U-shaped plate 8, as... Figure 3 and Figure 4 As shown, a second spring 10 is installed at the bottom of both sides of the U-shaped plate 8. The bottom of the second spring 10 is also installed inside the protective frame 3. Both ends of both sides of the U-shaped plate 8 are equipped with locking blocks 9. The two ends of one side of the two buffer strips 4 are provided with locking grooves. The locking blocks 9 can slide into the locking grooves. Therefore, when the U-shaped plate 8 moves downward, it squeezes the second spring 10 and simultaneously drives the locking blocks 9 downward. At this time, the buffer strips 4 are placed on the protective frame 3, aligning the locking grooves with the locking blocks 9. Then, the pressing post 6 is released, and the plate is reset under the action of the first spring 7 and the second spring 10, allowing the locking blocks 9 to be locked into the locking grooves, thus fixing the buffer strips 4. Figure 3 and Figure 4As shown, when it is necessary to remove the buffer strip 4, press the pressing column 6 again to make the U-shaped plate 8 continue to move downward a certain distance. The locking blocks 9 at both ends of the U-shaped plate 8 will slide out of the locking groove of the buffer strip 4, thereby releasing the fixation of the buffer strip 4, and the buffer strip 4 can be removed from the protective frame 3.

[0027] Example 2: Please refer to Figure 5 , Figure 6 and Figure 7 Based on Embodiment 1, a locking mechanism is also disclosed, the specific structure of which is as follows:

[0028] The locking mechanism includes a rotating column 13, which is slidably connected to both sides of the protective frame 3 and fixedly connected to the top of the secondary support frame 5. A sliding block 15 is installed on the outer wall of one side of the rotating column 13. A sliding groove 17 is provided inside the protective frame 3, and the sliding block 15 is slidably connected to the inside of the sliding groove 17. A threaded rod 16 is installed inside the sliding block 15. Threaded grooves matching the threaded rod 16 are provided on both sides of the protective frame 3. Moving grooves 14 are provided on both sides of the secondary support frame 5. A connecting rod 12 is slidably connected inside the moving groove 14 through a moving block. One end of the connecting rod 12 is rotatably connected to the inside of the protective frame 3. A support leg 19 is rotatably connected to one side of the secondary support frame 5. A third spring 20 is installed at one end of the support leg 19 and one end of the third spring 20 is installed inside the secondary support frame 5.

[0029] When using the display screen body 1, such as Figure 5 and Figure 6 As shown, by first removing the threaded rod 16 from the threaded groove, moving the threaded rod 16 away from the sliding block 15, the secondary support frame 5 is unlocked, and can then slide downwards. As the secondary support frame 5 slides, it will cause the rotating column 13 and the sliding block 15 to slide together. Figure 5 and Figure 6 As shown, since the secondary support frame 5 has movable slots 14 on both sides, and a connecting rod 12 is slidably connected inside the movable slots 14 via movable blocks, with one end of the connecting rod 12 rotatably connected to the inside of the protective frame 3, when the secondary support frame 5 moves downward, it will cause one end of the connecting rod 12 to slide inside the movable slot 14, causing the other end of the connecting rod 12 to rotatably connect to the protective frame 3. This causes the connecting rod 12 to push the secondary support frame 5 away from the protective frame 3. At this time, the secondary support frame 5 rotates, giving it a certain angle, allowing it to be supported on the ground. Figure 5 and Figure 6 As shown, after the secondary support frame 5 moves to the appropriate position, the threaded rod 16 is screwed into the threaded grooves on both sides of the protective frame 3, and the threaded end of the threaded rod 16 is locked inside the rotating column 13 and the sliding block 15, thereby fixing the rotating column 13 and the sliding block 15 and locking the secondary support frame 5 in the current position. Figure 7As shown, the support leg 19 on one side of the secondary support frame 5 unfolds under the action of the third spring 20 and contacts the support surface, providing support for the secondary support frame 5 and enhancing the overall stability of the display screen. Figure 5 and Figure 6 As shown, when the secondary support frame 5 is not needed, the threaded rod 16 is rotated in the opposite direction to unscrew the threaded rod 16 from the threaded grooves on both sides of the protective frame 3, thereby releasing the lock on the secondary support frame 5. Then, the secondary support frame 5 is pushed upward so that it slides back to its initial position in the sliding grooves 18 on both sides of the protective frame 3. The support leg 19 is gradually squeezed and retracted during the movement of the secondary support frame 5.
