Description

Technical Field

[0001] This utility model relates to the field of display screen installation technology, and in particular to an adjustable-pitch display screen mounting screw assembly. 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 mounted on walls or brackets using screw assemblies, improving ease of use. However, the spacing of traditional screw assemblies is difficult to adjust flexibly, resulting in poor adaptability to displays of different sizes. For example, if the mounting hole spacing of a newly purchased display does not match the screw spacing of an existing mounting bracket, it may be impossible to install directly due to the inability to adjust, requiring custom-made adapters or the purchase of new, compatible brackets, increasing both cost and time. Furthermore, the fixed screw spacing means that if installers discover a mismatch during installation, they must spend considerable time re-measuring, repositioning, and drilling to accommodate the new spacing requirements. This process involves tool changes and secondary damage to the wall or mounting surface, significantly reducing installation efficiency, especially in large-scale display installation projects, leading to a substantial increase in time costs. Therefore, designing screw assemblies that can flexibly adjust the distance between screw components to adapt to different display mounting requirements has become a key issue in display installation technology. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an adjustable-pitch display screen mounting screw assembly.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable-pitch display screen mounting screw assembly, comprising: a guide rail, a slider slidably engaged in the middle of the guide rail, multiple fixing teeth evenly fixed on one side of the middle of the guide rail, a movable groove in the middle of the slider, a pressing hole in the middle of one end of the slider, a sliding hole in the middle of one side of the slider, the sliding hole and the pressing hole respectively communicating with the movable groove, a limit sliding groove being formed below the middle of the movable groove, and the pressing hole... A pressure rod is slidably engaged in the middle of the slide hole, and a top rod is slidably engaged at one end of the middle of the slide hole. A spring is fixedly installed at one end of the top rod, and a movable plate is fixedly installed at one end of the spring. An inclined slide groove is opened in the middle of the movable plate, and a slide rod is slidably engaged in the middle of the inclined slide groove. One end of the pressure rod is fixedly connected to the slide rod. The end of the pressure rod is slidably engaged with the inclined slide groove opened in the movable plate through the slide rod. The lower end of the inclined slide groove is slidably engaged with the middle of the limiting slide groove, and the end of the top rod abuts against the fixed tooth.

[0006] In a preferred embodiment, a T-shaped lever is fixedly mounted on the upper end of the slider, and mounting screws are threaded to the middle of the other end of both the slider and the T-shaped lever.

[0007] In a preferred embodiment, a groove is provided in the middle of the upper end of the guide rail, and the T-shaped lever is slidably engaged in the middle of the groove.

[0008] In a preferred embodiment, a screw mounting groove is provided in the middle of the lower end of the guide rail, and the mounting screw is located in the middle of the screw mounting groove.

[0009] In a preferred embodiment, mounting plates are fixedly installed at each of the four corners of the guide rail.

[0010] In a preferred embodiment, each of the four mounting plates is threaded with a limit screw at its center.

[0011] In a preferred embodiment, the guide rail is provided in multiple sets, and multiple sets of sliders are evenly slidably engaged in the middle of each set of guide rails.

[0012] In a preferred embodiment, one end of the mounting screw is located above the center of the groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. When using this utility model, if the spacing needs to be adjusted to adapt to the spacing of different display screen mounting holes, the user only needs to press the pressure rod located in the pressing hole to drive the movable plate to move. During the movement of the movable plate, the cooperation between its inclined slide groove and the slide rod causes the slide rod to move along the limiting slide groove, thereby pushing the top rod to disengage from the fixed teeth. At this time, the slider can slide freely on the guide rail to the desired position. After releasing the pressure rod, the top rod re-engages with the fixed teeth under the action of the spring piece, quickly locking the slider position and completing the distance adjustment between the screw components. The whole process does not require additional tools, greatly improving the convenience and flexibility of spacing adjustment and solving the problem of traditional fixed spacing installation methods.

[0015] 2. When using this utility model, during the installation of the display screen, the installer can directly pass the mounting screw through the screw mounting groove and screw it into the screw hole at one end of the slider and T-shaped lever, and then screw it through the mounting hole of the display screen for positioning and fastening. There is no need to find a matching screw hole, which simplifies the installation process and further shortens the installation time. Attached Figure Description

[0028] Example 1: As Figure 1-5As shown, this utility model provides a technical solution: an adjustable-pitch display screen mounting screw assembly, comprising: a guide rail 1, a slider 2 slidably engaged in the middle of the guide rail 1, a plurality of fixing teeth 12 evenly fixed on one side of the middle of the guide rail 1, a movable groove 24 in the middle of the slider 2, a pressing hole 25 in the middle of one end of the slider 2, a sliding hole 23 in the middle of one side of the slider 2, the sliding hole 23 and the pressing hole 25 respectively communicating with the movable groove 24, a limiting sliding groove 32 in the lower part of the middle of the movable groove 24, and a pressure rod slidably engaged in the middle of the pressing hole 25. 30. A push rod 26 is slidably engaged at one end of the middle of the sliding hole 23. A spring piece 27 is fixedly installed at one end of the push rod 26. A movable plate 28 is fixedly installed at one end of the spring piece 27. An inclined sliding groove 29 is opened in the middle of the movable plate 28. A sliding rod 31 is slidably engaged in the middle of the inclined sliding groove 29. One end of the pressure rod 30 is fixedly connected to the sliding rod 31. The end of the pressure rod 30 is slidably engaged with the inclined sliding groove 29 opened in the movable plate 28 through the sliding rod 31. The lower end of the inclined sliding groove 29 is slidably engaged with the middle of the limiting sliding groove 32. The end of the push rod 26 abuts against the fixed tooth 12.

[0029] In this embodiment, the structure of the guide rail 1 and the slider 2 facilitates the adjustment of the spacing. The slider 2 can slide smoothly in the middle of the guide rail 1. When the spacing needs to be adjusted to adapt to the spacing of different display screen mounting holes, the user only needs to press the pressure rod 30 located in the pressing hole 25. Since the pressure rod 30 is slidably connected to the inclined slide groove 29 of the movable plate 28 through the slide rod 31, pressing the pressure rod 30 will drive the movable plate 28 to move. During the movement of the movable plate 28, the cooperation between its inclined slide groove 29 and the slide rod 31 causes the slide rod 31 to move along the limiting slide groove 32, thereby pushing the top rod 26 to disengage from the fixed tooth 12. At this time, the slider 2 can slide freely on the guide rail 1. Move the slider to the desired position; once adjusted, release the pressure rod 30. Under the action of the spring piece 27, the top rod 26 will re-engage with the fixing tooth 12, quickly locking the position of the slider 2 and completing the spacing adjustment. The entire process requires no additional tools, greatly improving the convenience and flexibility of adjusting the spacing between screw components when installing the display screen. It solves the problem of the traditional screw component fixed spacing installation method. By precisely adjusting the position of the slider 2 on the guide rail 1, it can be ensured that the display screen is in an ideal horizontal and vertical state after installation. The sliding cooperation between the slider 2 and the guide rail 1, as well as the locking mechanism between the top rod 26 and the fixing tooth 12, make the installation position more accurate.

[0030] Example 2: Figure 1-4As shown, a T-shaped lever 21 is fixedly installed on the upper end of the slider 2. The middle of the other end of both the slider 2 and the T-shaped lever 21 is threaded with a mounting screw 22. A groove 11 is opened in the middle of the upper end of the guide rail 1. The T-shaped lever 21 is slidably engaged in the middle of the groove 11. A screw mounting groove 15 is opened in the middle of the lower end of the guide rail 1. The mounting screw 22 is located in the middle of the screw mounting groove 15. Mounting plates 13 are fixedly installed at the four corners of the guide rail 1. Limiting screws 14 are threadedly connected in the middle of the four mounting plates 13. The guide rail 1 is provided with multiple sets. Multiple sets of sliders 2 are evenly slidably engaged in the middle of each set of guide rail 1. One end of the mounting screw 22 is located above the middle of the groove 11.

[0031] In this embodiment, the T-shaped lever 21 fixedly installed on the upper end of the slider 2 provides a more intuitive and convenient way for the user to adjust the position of the slider 2. The T-shaped lever 21 is slidably engaged in the groove 11 opened in the middle of the upper end of the guide rail 1. It works in conjunction with the pressing rod 30 to adjust the position of the slider 2. The user can directly move the T-shaped lever 21 to quickly drive the slider 2 to slide on the guide rail 1. The other end of both the slider 2 and the T-shaped lever 21 are threaded with mounting screws 22, and the screw mounting groove 15 is opened in the middle of the lower end of the guide rail 1, which makes the installation more convenient. During installation, the installation personnel can more easily connect and fix the display screen to the slider 2. The mounting screws 22 can directly pass through the screw mounting slots 15 and screw into the screw holes at one end of the slider 2 and the T-shaped lever 21, and then pass through the mounting holes of the display screen for positioning and tightening. There is no need to find matching screw holes, which simplifies the installation process and further shortens the installation time. The mounting plates 13 are fixedly installed at the four corners of the guide rail 1, and each mounting plate 13 has a limit screw 14 threaded in the middle, which provides additional stability for the installation of the guide rail 1. When installing the guide rail 1 onto the wall or other supporting structure, tightening the limit screws 14 can firmly fix the guide rail 1 to the mounting surface, effectively preventing the guide rail 1 from shifting or shaking due to vibration, external pulling force, or other factors during use.
