Description

Technical Field

[0001] This utility model relates to the field of display screen installation technology, and in particular to a display screen mounting screw structure that is easy to align and guide. Background Technology

[0002] In the installation process of modern display devices, different display screen specifications and installation environments often require flexible adjustment of the spacing of the mounting screws. Before starting to install the display screen, it is necessary to carefully confirm the display screen model, size, and the layout and specifications of the mounting holes on the back. At the same time, check whether the mounting surface, such as the wall or bracket, is flat and sturdy and can bear the weight of the display screen. Based on the confirmed information, select the appropriate length of the main screw rod, ensuring that the screw rod can penetrate the mounting surface and leave enough length for subsequent operations. Prepare the corresponding size of fixing nuts, adjusting nuts, and matching bolts and other installation tools.

[0003] In existing technologies, displays are typically fixed to walls or brackets using screw assemblies, improving ease of use. However, traditional screw structures lack precise guiding components such as guide sleeves and positioning plates. During screw installation, alignment with the display mounting holes and guide rails relies entirely on manual visual inspection. In confined spaces or poor lighting conditions, alignment is extremely difficult and prone to errors. Misalignment necessitates readjustment, significantly extending installation time and resulting in low overall installation efficiency, especially for large-scale displays. Furthermore, repeated screw adjustments to align with the screw holes can generate significant friction and lateral forces, potentially causing wear on the inner walls of the screw holes. This can enlarge the holes, making their shape irregular and affecting the tightness and stability of the screw connection. Over time, screw loosening may occur, leading to display screen wobbling. Therefore, designing a screw-guiding mechanism that reduces the need for repeated screw adjustments due to alignment errors in confined spaces or poor lighting conditions is a crucial issue in display installation technology.

[0028] Example 1: As Figure 1-5 As shown, this utility model provides a technical solution: an easy-to-align and guide display screen mounting screw structure, including: a guide sleeve 1, the guide sleeve 1 including a semi-cylindrical sleeve 11 and a semi-cylindrical sleeve 23, the guide sleeve 1 and the semi-cylindrical sleeve 23 are snapped together, a guide hole 12 is provided in the middle of the guide sleeve 1, side plates 14 are fixedly installed on both sides of the middle of the semi-cylindrical sleeve 11 and the semi-cylindrical sleeve 23, a sliding groove 16 is provided in the middle of the side plate 14 on one side of the semi-cylindrical sleeve 11, a moving groove 17 is provided at one end of the side plate 14 on one side of the semi-cylindrical sleeve 11, the sliding groove 16 and the moving groove 17 are connected, a fixing plate 20 is fixedly installed in the middle of the sliding groove 16, a spring piece 21 is fixedly installed at the upper and lower ends of the fixing plate 20, a plug rod 22 is fixedly installed at one end of each of the two spring pieces 21, and the two plug rods 22 are respectively slidably snapped into the middle of the two sliding grooves 16. Each of the two insert rods 22 has a lever 19 fixedly installed on one side of its end. The two levers 19 are slidably engaged in the middle of the lever groove 17. The other side of the semi-cylindrical sleeve 11 has positioning pins 15 fixedly installed above and below the middle of its other side. The side plate 14 of the semi-cylindrical sleeve 23 has inclined slots 25 opened above and below the middle of its side. The two insert rods 22 are slidably engaged in the middle of the inclined slots 25. The other side plate 14 of the semi-cylindrical sleeve 23 has positioning grooves 24 opened above and below the middle of its other side. The two positioning pins 15 are inserted into the positioning grooves 24. The semi-cylindrical sleeve 11 and the semi-cylindrical sleeve 23 are engaged through the internal structure of the two sets of side plates 14 on both sides. The diameter of the top of the guide hole 12 is larger than the bottom diameter. The lower end of the middle of the semi-cylindrical sleeve 11 and the semi-cylindrical sleeve 23 is fixedly installed with a positioning plate 13. The bottom diameter of the positioning plate 13 is equal to the bottom diameter of the guide hole 12.

[0029] In this embodiment, the semi-cylindrical sleeve 11 and semi-cylindrical sleeve 23 are snapped together using the internal structure of the side plate 14. During installation, the semi-cylindrical sleeve 23 is first quickly positioned by being snapped into the screw hole by the inclined pressure block 32 below. Then, the positioning post 15 on the side of the semi-cylindrical sleeve 11 is aligned with the positioning groove 24 and inserted, while the insertion rod 22 is aligned with the inclined slot 25. As the two approach each other, the insertion rod 22 automatically slides into the inclined slot 25 due to the inclined surface, easily completing the snap-fit. The top diameter of the guide hole 12 is larger than the bottom diameter. This flared design better guides the screws used to fix the display screen into the guide hole 12, making it easier for them to enter and move along the axis of the guide hole 12, greatly reducing the installation difficulty and improving the accuracy of installation. For efficiency, the positioning plate 13 at the lower end of the semi-cylindrical sleeve 11 and the semi-cylindrical sleeve 23 has the same bottom diameter as the bottom diameter of the guide hole 12. When installing the guide sleeve 1, it can be accurately fixed in the corresponding position, ensuring the relative positional accuracy of the guide sleeve 1 and other components. When disassembling, by moving the lever 19, the insertion rod 22 can be driven out of the inclined slot 25, and the semi-cylindrical sleeve 11 and the semi-cylindrical sleeve 23 can be quickly separated. The spring piece 21 installed on the fixing plate 20 provides elastic support for the insertion rod 22. During the process of the insertion rod 22 being inserted into or out of the inclined slot 25, the spring piece 21 can effectively absorb and buffer the impact force, reduce the rigid collision between components, reduce the risk of component damage, and thus extend the service life of the guide sleeve 1.

[0030] Example 2: Figure 1-3 As shown, a groove 26 is provided in the middle of one side of the lower end of the semi-cylindrical sleeve 23. A T-shaped slide rod 28 is slidably engaged in the middle of the groove 26. The diameter of one end of the T-shaped slide rod 28 is larger than the diameter of the groove 26. Limiting grooves 27 are provided on both sides of the middle of the groove 26. Limiting blocks 29 are fixedly installed on both sides of the middle of one end of the T-shaped slide rod 28. The limiting blocks 29 abut against the two ends of the limiting grooves 27. A fixing groove 30 is provided below the middle of the other end of the T-shaped slide rod 28. A spring 31 is fixedly installed on the top of the fixing groove 30. An inclined pressure block 32 is fixedly installed on one end of the spring 31. The inclined side of the inclined pressure block 32 cooperates with one end of the groove 26.

[0031] In this embodiment, before fixing the display screen, the T-shaped slide bar 28 at the bottom of the semi-cylindrical sleeve 23 is pulled outward along the slide groove 26, so that the inclined pressure block 32 enters the fixing groove 30 under the action of the inclined surface and the upper spring 31. Then, the entire semi-cylindrical sleeve 23 is slid against the slide rail used to fix the display screen. When it slides into the screw hole, the T-shaped slide bar 28 is pressed to make the inclined pressure block 32 at the end spring back and lock into the screw hole, thus positioning the semi-cylindrical sleeve 23. No additional tools are needed; positioning can be achieved simply by pressing. Then, the semi-cylindrical sleeve 11 is engaged with the semi-cylindrical sleeve 23 through the internal structure of the side plate 14. After positioning, the screw is screwed into the screw hole along the guide hole 12. During the process, the user can pull the T-shaped slide bar 28 to retract the inclined pressure block 32 into the fixing groove 30 as needed, thereby avoiding obstruction to the screw.
