Description

Technical Field

[0001] This utility model relates to the field of display screen processing technology, and in particular to a display screen positioning device for liquid crystal display screen processing. Background Technology

[0002] A display screen positioning device is a device or structure used to fix and position a display screen in a designated location. Its main function is to ensure that the display screen is placed stably and accurately during installation, while maintaining its position, so as to prevent the display screen from moving or tilting due to external forces during use. In order to ensure that the display screen is accurately positioned in the predetermined position during installation and to avoid human error, a display screen positioning device is required.

[0003] Display screen positioning devices can be divided into several types, namely fixed positioning devices, adjustable positioning devices, and adjustable positioning devices. Each of these positioning devices has its own unique advantages. The choice of the appropriate type depends on the specific production requirements, operating environment, and display screen specifications. Among them, adjustable positioning devices allow for fine-tuning of the display screen position within a certain range and usually include adjustable support arms or slide rails.

[0004] However, existing LCD screen positioning devices often require the customization of multiple brackets or positioning components of different specifications when dealing with screens of different sizes. This not only increases production costs but also leads to operational inconvenience. Each time a screen needs to be replaced, the bracket position must be readjusted, and sometimes the existing device may even need to be disassembled—a cumbersome and inefficient process. More importantly, traditional positioning devices typically lack quick disassembly and adjustment capabilities, requiring operators to invest significant time in adjustments, thus failing to meet the demands of rapid and efficient production. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a display screen positioning device for LCD screen processing, aiming to improve the problem that positioning devices cannot meet the needs of different sized display screens and require separate customization, which is wasteful.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a display screen positioning device for LCD screen processing, comprising a base, a positioning groove inside the base, a bracket on the top of the base, a locking component inside the bracket, and a fixing component inside the bracket;

[0007] The locking component includes a limiting post, both ends of which are fixedly connected to the inside of the bracket. The outer wall of the limiting post is slidably connected with symmetrically arranged locking blocks. The outer wall of the bracket is fixedly connected with a positioning block, which is engaged with a positioning groove. The outer wall of the bracket is slidably connected to the inside of the positioning groove. The locking block is engaged with the base. The outer wall of the limiting post is provided with a reset component.

[0008] As a further description of the above technical solution:

[0009] The reset assembly includes a first spring, which is sleeved on the outer wall of a limiting post, and both ends of the first spring are fixedly connected between the locking blocks.

[0010] As a further description of the above technical solution:

[0011] The fixing component includes a screw, which is threadedly connected inside the bracket, and a pressure plate is rotatably connected to one end of the screw.

[0012] As a further description of the above technical solution:

[0013] The bracket is fixedly connected to a second limiting column, and a connecting block is slidably connected to the outer wall of the second limiting column.

[0014] As a further description of the above technical solution:

[0015] Both ends of the connecting block are fixedly connected to connecting rods, and one end of each connecting rod is fixedly connected to a pull rod.

[0016] As a further description of the above technical solution:

[0017] The other end of the connecting rod is fixedly connected to a disassembly ring, which is slidably connected to the outer wall of the bracket.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the limiting post is fitted with a second spring.

[0020] As a further description of the above technical solution:

[0021] One end of the second spring is fixedly connected to the inside of the bracket, and the other end of the second spring is fixedly connected to the top of the connecting block.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the bracket is first inserted into the positioning groove by the positioning block at the bottom. The positioning block and the positioning groove are fitted and positioned. At the same time, the locking block inside the bracket is locked with the base, which achieves the effect of adapting to different sizes of display screens. This solves the problem that the positioning device cannot meet the needs of different sizes of display screens and requires separate customization, which is wasteful. This improves the convenience of the display screen positioning device.

[0024] 2. In this utility model, the pull rod drives the connecting rod to lift, and the connecting rod slides on the outer wall of the bracket through the disassembly ring. Then the disassembly ring pushes the locking block into the bracket, thereby separating the locking block from the bottom of the base, achieving the effect of facilitating the disassembly of the clamp, solving the problem of the cumbersome adjustment of the clamp position, and improving the practicality of the display positioning device.

[0030] 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.

[0031] Reference Figures 1-3 An embodiment of this utility model is provided: a display screen positioning device for processing liquid crystal display screens, including a base 1, a positioning groove 2 inside the base 1, a bracket 3 on the top of the base 1, a locking component inside the bracket 3, and a fixing component inside the bracket 3.

[0032] The locking assembly includes a limiting post 5, with both ends of the limiting post 5 fixedly connected inside the bracket 3. Symmetrically arranged locking blocks 6 are slidably connected to the outer wall of the limiting post 5. The function of the locking blocks 6 is to fix and lock the bracket 3 to the base 1, ensuring that the bracket's position does not move unexpectedly. A positioning block 4 is fixedly connected to the outer wall of the bracket 3. The positioning block 4 engages with the positioning groove 2 inside the base 1, serving to position the bracket and ensuring that the bracket 3 is stably fixed to the base 1 during installation. The slidable connection of the outer wall of the bracket 3 inside the positioning groove 2 provides some adjustment space to accommodate displays of different sizes. The engagement of the locking blocks 6 with the base 1 ensures a secure lock on the bracket, avoiding errors caused by unstable bracket position during processing. A reset assembly is provided on the outer wall of the limiting post 5, including a first spring 7. The first spring 7 is sleeved on the outer wall of the limiting post 5, with both ends of the first spring 7 fixedly connected between the locking blocks 6. The first spring 7 provides a certain rebound force, which can quickly restore the locking block 6 to its original position when it shifts, ensuring the accuracy and reliability of the positioning. The fixing component includes a screw 14, which is threaded into the bracket 3. The position of the bracket 3 can be adjusted by rotating the screw 14. One end of the screw 14 is rotatably connected to a pressure plate 15. The function of the pressure plate 15 is to move downward or upward by adjusting the rotation of the screw 14, thereby precisely fixing the display screen and ensuring that the display screen will not move due to external force or vibration during the processing.

[0033] Specifically, when adjusting the position of the bracket 3 on the base 1 to accommodate different sized displays, the bracket 3 is first inserted into the precisely designed positioning groove 2 via the positioning block 4 at the bottom. The positioning block 4 and the positioning groove 2 interlock, ensuring the bracket 3 is securely installed. Simultaneously, the locking block 6 inside the bracket 3 is tightly engaged and locked firmly to the base 1. The locking block 6 is precisely positioned within the bracket 3 by the limiting post 5, preventing the bracket from shifting or loosening. To provide more stable support, the locking block 6 is supported by the tension of the first spring 7, ensuring it remains firmly pressed against the bottom of the base 1, further enhancing stability. This process of adjusting the bracket 3 is both simple and efficient, adaptable to displays of different sizes, and ensures operational flexibility and reliability. When fixing the display, rotating the screw 14 precisely lowers the pressure plate 15, clamping the display evenly and securely, ensuring the display is firmly fixed and preventing loosening or displacement during use.

[0034] Reference Figure 3The bracket 3 has a fixed internal limit post 9, and a connecting block 11 is slidably connected to the outer wall of the limit post 9. The connecting block 11 connects the limit post 9 to the connecting rod 8, providing support and positioning functions to ensure the stability and adjustability of the entire bracket structure. Both ends of the connecting block 11 are fixedly connected to the connecting rod 8, which transmits force and drives the pull rod 13 to move, ensuring that the adjustment of the bracket 3 can be effectively achieved. One end of the connecting rod 8 is fixedly connected to the pull rod 13, which is used to adjust the position of the entire bracket 3, making it convenient to change the installation angle or height of the display screen as needed. The other end of the connecting rod 8 is fixedly connected to the disassembly ring 10, which is slidably connected to the outer wall of the bracket 3. The disassembly ring 10 provides a function for quick disassembly or adjustment of the position of the bracket 3, improving the convenience of installation and maintenance. A second spring 12 is sleeved on the outer wall of the limit post 9, which provides elastic support and helps the connecting block 11 and the pull rod 13 to reset or relieve external forces when needed. One end of the second spring 12 is fixedly connected to the inside of the bracket 3, and the other end of the second spring 12 is fixedly connected to the top of the connecting block 11. This ensures that the connecting block 11 can move smoothly under the action of the pull rod 13. At the same time, when no adjustment is needed, the tension of the spring will restore the structure to its original position, avoiding unnecessary loosening or positional errors, thereby ensuring the accuracy of the display screen installation process.

[0035] Specifically, adjusting the position of the bracket 3 on the base 1 is very simple. First, simply pull the lever 13 to easily raise the connecting rod 8. The connecting rod 8 slides through the disassembly ring 10 installed on the outer wall of the bracket 3, allowing the disassembly ring 10 to precisely push the locking block 6 into the bracket 3, thereby separating the locking block 6 from the bottom of the base 1. This ensures that the bracket 3 can be quickly pulled out of the positioning slot 2 for easy position adjustment. During the adjustment process, the sliding of the disassembly ring 10 is smooth and stable, and the separation of the locking block 6 from the base is both smooth and efficient, avoiding unnecessary friction or jamming. After adjustment, simply release the lever 13. Supported by the tension of the second spring 12, the disassembly ring 10 will automatically reset, quickly returning to its initial state, ensuring that the bracket 3 can be firmly fixed in the new position.

[0036] Working principle: When using the LCD screen positioning device for LCD screen processing, to first adapt to different sizes of screens, the bracket 3 is adjusted on the base 1 by inserting the bracket 3 into the positioning groove 2 through the positioning block 4 at the bottom. The positioning block 4 and the positioning groove 2 are engaged and positioned. At the same time, the locking block 6 inside the bracket 3 is locked to the base 1. The locking block 6 is limited in the bracket 3 by the limiting post 5, and is supported by the tension of the first spring 7 so that the locking block 6 is pressed against the bottom of the base 1, thus achieving the effect of adapting to different sizes of screens. Then, when fixing the screen, the screw 14 is rotated to drive the pressure plate 15 to descend and fix the screen.

[0037] When it is necessary to adjust the position of the bracket 3 on the base 1, simply lift the connecting rod 8 by pulling the lever 13. The connecting rod 8 slides on the outer wall of the bracket 3 through the disassembly ring 10. Then, the disassembly ring 10 pushes the locking block 6 into the bracket 3, thereby separating the locking block 6 from the bottom of the base 1. The bracket 3 can then be pulled out from the positioning groove 2 to adjust its position on the base 1. When the lever 13 is released, the tension of the second spring 12 will support the disassembly ring 10 to return to its original position, thus facilitating the disassembly of the fixture.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
