Description

Technical Field

[0001] This utility model relates to the field of LCD screen mounting structures, and more particularly to a mounting structure that is compatible with LCD screens of different sizes. Background Technology

[0002] An LCD screen uses liquid crystal material as its basic component, filling the space between two parallel plates. By applying voltage, the arrangement of molecules within the liquid crystal material is altered to achieve light blocking and transmission, thus displaying images of varying shades and textures. Furthermore, by adding a three-color filter layer between the two plates, color images can be displayed. LCD screens consume very little power, making them highly favored by engineers and suitable for battery-powered electronic devices.

[0003] Utility model patent application CN215182864U discloses an installation structure compatible with LCD screens of different sizes, including a metal mounting plate mounted on the front panel of a CNC system; an LCD screen fixing bracket movably mounted on the metal mounting plate; the LCD screen fixing bracket includes a support plate fixed to the metal mounting plate, a fixing ring for securing the LCD screen is provided around the periphery of the support plate, and a plurality of fasteners for fixing the LCD screen within the fixing ring are provided around the fixing ring; simultaneously, a plurality of fasteners for supporting the LCD screen are evenly distributed on the support plate within the fixing ring. The detachable boss of the LCD screen, with the relative position of the metal mounting plate and the front panel of the CNC system remaining unchanged, allows for adjustment of the display center position to a suitable location by directly adjusting the position of the LCD screen mounting bracket on the metal mounting plate when the aspect ratio is fixed for different models of LCD screens, without the need to replace different models of LCD screen mounting brackets. However, when this structure limits the LCD screen, the side wall of the LCD screen and the fixing ring are in close contact, and there is no mutual force between the two, which to some extent reduces the stability of the installed LCD screen.

[0004] Therefore, it is necessary to provide a new mounting structure that is compatible with LCD screens of different sizes to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an installation structure that is compatible with LCD screens of different sizes.

[0006] The present invention provides an installation structure compatible with LCD screens of different sizes, comprising a metal mounting plate mounted on the front panel of a CNC system, wherein a mounting device for mounting the LCD screen is mounted on the metal mounting plate, and the mounting device and the metal mounting plate are capable of relative movement. The mounting device includes a connecting plate, two fixed plates, and two movable frames. The two fixed plates are respectively fixedly connected to the two ends of the connecting plate in the longitudinal direction, and the two movable frames are respectively disposed on both sides of the connecting plate in the transverse direction. Each end of the movable frame is provided with an elastic element, and the movable frame is connected to the two fixed plates respectively through the elastic elements at the two ends. The pressure of the movable frame on the side wall of the LCD screen can be adjusted by the elastic elements.

[0007] Preferably, the elastic element includes a sliding frame and a first spring. One end of the sliding frame is fixedly connected to a fixed plate, and the other end of the sliding frame is slidably connected to a groove opened at the end of the movable frame. A threaded rod is threadedly connected to the sliding frame, and one end of the threaded rod is rotatably connected to a sliding plate. The sliding plate is slidably disposed in the groove. The two ends of the first spring are respectively fixedly connected to the side wall of the sliding plate and the inner wall of the groove.

[0008] Preferably, both the sliding frame and the sliding plate are provided with through grooves, and a limiting strip is fixedly connected in the sliding groove. The limiting strip is movably inserted into the through groove of the sliding frame and the sliding plate.

[0009] Preferably, the metal mounting plate has multiple mounting holes, and the connecting plate is threaded with multiple bolts, which are threaded to the inner wall of the mounting holes.

[0010] Preferably, a side plate is also fixedly installed on the movable frame, and bolts are threadedly connected to the side plate, with the bolts on the side plate being threadedly connected to the inner wall of the mounting hole.

[0011] Preferably, the movable frame is equipped with a ramp.

[0012] Preferably, the movable frame is provided with support devices for supporting the LCD screen on both opposite side walls, and the height of the support devices can be adjusted according to the thickness of the LCD screen.

[0013] Preferably, the support device includes a support plate, a second spring, and a pressure plate. One end of the support plate is fixedly connected to the side wall of the movable frame, and the other end of the support plate is fixedly connected to a threaded sleeve. A movable column is threadedly connected to the threaded sleeve, and a groove is provided at the end of the movable column. One end of the second spring is fixedly connected to the bottom wall of the groove of the movable column, and the other end of the second spring is fixedly connected to the pressure plate. The pressure plate is movably disposed in the groove of the movable column, and one end of the pressure plate extends to the outside of the groove of the movable column.

[0014] Compared with related technologies, the mounting structure provided by this utility model, which is compatible with LCD screens of different sizes, has the following advantages:

[0015] 1. When the LCD screen is located between the two movable frames, the first spring needs to recover its deformation, which drives the movable frame to reset. At this time, the threaded rod can be rotated, which causes the threaded rod to move the slide plate closer to the fixed plate, thereby stretching the first spring. The movable frames on both sides apply a certain force to the side wall of the LCD screen, thereby improving the stability of the LCD screen after installation.

[0016] 2. After the LCD screen is installed, it comes into contact with the movable column. Under the pressure of the LCD screen, the pressure plate moves completely into the groove of the movable column. The second spring is compressed, and the pressure plate applies force to the LCD screen through the second spring, further stabilizing the LCD screen. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1-6 ,in, Figure 1 A schematic diagram of the installation structure provided by this utility model, which is compatible with LCD screens of different sizes; Figure 2 for Figure 1 The diagram shows a decomposed structural representation of the structure.

[0026] Figure 3 for Figure 1 A partial structural diagram of the structure shown; Figure 4 for Figure 1 The diagram shows the structure of the elastic element. Figure 5 for Figure 3 The diagram shows the structure of the support device. Figure 6 for Figure 5 The diagram shows a cross-sectional view of the support device.

[0027] In the specific implementation process, such as Figures 1-6 As shown, the system includes a metal mounting plate 2 installed on the front panel 1 of the CNC system. The metal mounting plate 2 is equipped with a mounting device for mounting the LCD screen 5. The mounting device and the metal mounting plate 2 can move relative to each other. The mounting device includes a connecting plate 6, two fixed plates 3 and two movable frames 4. The two fixed plates 3 are respectively fixedly connected to the two ends of the longitudinal direction of the connecting plate 6. The two movable frames 4 are respectively arranged on both sides of the transverse direction of the connecting plate 6. Both ends of the movable frames 4 are provided with elastic elements. The movable frames 4 are connected to the two fixed plates 3 through the elastic elements at both ends. The pressure of the movable frames 4 on the side wall of the LCD screen 5 can be adjusted by the elastic elements.

[0028] The elastic element includes a sliding frame 7 and a first spring 9. One end of the sliding frame 7 is fixedly connected to the fixed plate 3, and the other end of the sliding frame 7 is slidably connected to the groove 8 opened at the end of the movable frame 4. A threaded rod 11 is threadedly connected to the sliding frame 7, and a sliding plate 10 is rotatably connected to one end of the threaded rod 11. The sliding plate 10 is slidably disposed in the groove 8. The two ends of the first spring 9 are fixedly connected to the side wall of the sliding plate 10 and the inner wall of the groove 8, respectively. Both the sliding frame 7 and the sliding plate 10 are provided with through grooves. A limit strip is fixedly connected in the groove 8. The limit strip is movably inserted into the through grooves of the sliding frame 7 and the sliding plate 10. When the LCD screen 5 moves past the inclined platform 18 and enters between the two movable frames 4, the first spring 9 needs to restore its deformation, thereby driving the movable frame 4 to reset. At this time, the threaded rod 11 can be rotated, so that the threaded rod 11 drives the sliding plate 10 to move closer to the fixed plate 3, thereby stretching the first spring 9. The movable frames 4 on both sides apply a certain force to the side wall of the LCD screen 5, thereby improving the stability of the LCD screen 5 after installation.

[0029] The metal mounting plate 2 has multiple mounting holes 19. The connecting plate 6 is threaded with multiple bolts. The bolts on the connecting plate 6 are threaded to the inner wall of the mounting holes 19. The position of the mounting device on the metal mounting plate 2 can be adjusted according to the usage requirements. Select a suitable mounting hole 19, and tighten the bolts on the connecting plate 6 so that one end of the bolt moves into the corresponding mounting hole 19, thereby installing the mounting device on the metal mounting plate 2. The movable frame 4 is also fixedly mounted with a side plate 12. The side plate 12 is threaded with bolts. The bolts on the side plate 12 are threaded to the inner wall of the mounting holes 19. Rotating the bolts on the side plate 12 limits the position of the side plate 12.

[0030] An inclined platform 18 is installed on the movable frame 4. The LCD screen 5 is moved down, and the LCD screen 5 presses against the inclined surface of the inclined platform 18. Through the pressing of the LCD screen 5, the inclined platform 18 drives the movable frame 4 to move away from the LCD screen 5. The first spring 9 is stretched, which facilitates the installation of the LCD screen 5.

[0031] Support devices for supporting the LCD screen 5 are provided on both opposite side walls of the movable frame 4. The height of the support devices can be adjusted according to the thickness of the LCD screen 5. The support devices include a support plate 13, a second spring 17, and a pressure plate 16. One end of the support plate 13 is fixedly connected to the side wall of the movable frame 4, and the other end of the support plate 13 is fixedly connected to a threaded sleeve 14. A movable column 15 is internally threaded into the threaded sleeve 14. A groove is provided at the end of the movable column 15. One end of the second spring 17 is fixedly connected to the bottom wall of the groove of the movable column 15, and the other end of the second spring 17 is fixedly connected to the pressure plate 16. The pressure plate 16 is movably disposed in the groove of the movable column 15, and one end of the pressure plate 16 extends to the outside of the groove of the movable column 15. After the LCD screen 5 is installed, the LCD screen 5 contacts the movable column 15, and the pressure plate 16 moves completely under the pressure of the LCD screen 5. The second spring 17 is compressed within the groove of the movable column 15, further enhancing the stability of the LCD screen 5. Since the movable column 15 is threadedly connected to the threaded sleeve 14, the relative position of the movable column 15 and the threaded sleeve 14 can be adjusted to accommodate LCD screens 5 of different thicknesses. When disassembling the LCD screen, the movable brackets 4 on both sides can be pulled. When the inclined platform 18 does not limit the LCD screen 5, the second spring 17 pushes the LCD screen 5 to move through the pressure plate 16, facilitating the disassembly of the LCD screen 5. In addition, the TV function, power supply, backlight constant current drive, and TCON function can be integrated into the main board of the LCD screen mechanism. When matching different LCD screens 5, the main board remains unchanged; only the corresponding TCON power adapter board needs to be replaced to meet various screen matching requirements. Since the main board of the mechanism includes the TCON function, the overall cost of the whole machine is lower.

[0032] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
