Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a novel COB packaged display screen. Background Art

[0002] The traditional display screen approach is not only time-consuming and labor-intensive, but also costly because there is no ready-made suitable core light source component. COB technology is an emerging LED packaging technology. Unlike the traditional SMD surface mount packaging, it integrates the light-emitting chip into the PCB board instead of soldering it one by one. COB effectively improves the light color of the LED display screen, reduces risks, and reduces costs.

[0003] At present, the display screen is generally fixed to the wall by bolts, and the display screen is hung on the mounting frame, which usually does not have the function of adjusting the angle; and the existing display screen with adjustable angle mainly fixes the angle of the display screen after adjustment by a knob, which has poor stability and is prone to looseness, causing collision between the display screen and the wall, which is easy to damage the display screen and the wall, and if the display screen is adjusted after installation, the operation is extremely inconvenient.

[0028] Example:

[0029] Reference Figure 1-Figure 6 A novel COB packaged display screen includes a display screen body 1, a bracket 2 and a mounting seat 16, and also includes: an annular plate 6 fixedly connected to the side of the bracket 2 away from the display screen body 1, a limiting portion is arranged on the inner wall of the annular plate 6, and the display screen body 1 can adjust the angle with the mounting seat 16 through the limiting portion; an adjusting portion is arranged on the inner wall of the annular plate 6, and the adjusting portion can adjust the relative angle of at least part of the limiting portion; a buffer portion is arranged on the side of the mounting seat 16 close to the display screen body 1, and is used to buffer when the display screen body 1 is rotated downward.

[0030] Reference Figure 3-Figure 5 The limiting part includes a connecting shaft 7 fixedly connected to the inner wall of the annular plate 6, a buckle 8 is rotatably connected to the connecting shaft 7, a ratchet 9 is fixedly connected to the connecting shaft 7, a ratchet 10 is rotatably connected to the buckle 8, and an adjusting rod 11 is fixedly connected to the outer wall of the ratchet 10, the ratchet 9 and the ratchet 10 are located on the inner side of the buckle 8, and the adjusting rod 11 is located on the side of the ratchet 10 away from the buckle 8, wherein the buckle 8 matches the end of the mounting seat 16, and the ratchet 9 and the ratchet 10 are meshed with each other, wherein the specific structure of the ratchet 9 and the ratchet 10 can refer to the technical scheme in the prior art, and those skilled in the art can know it and will not be repeated here. Under the action of the ratchet 10, the ratchet 9 can only rotate in one direction.

[0031] Reference Figure 2 and Figure 4The adjusting part includes a push rod 12 which is slidably connected to the side where the two groups of annular plates 6 are away from each other. A wedge block 13 is fixedly connected to one end of the push rod 12 close to the annular plate 6. An isosceles trapezoidal hole is opened on the side of the wedge block 13 close to the adjusting rod 11. The adjusting rod 11 is located in the hole of the wedge block 13. A connecting rod 14 is fixedly connected to the side where the two groups of wedge blocks 13 are close to each other. The connecting rod 14 is slidably connected to the annular plate 6. A spring 15 is sleeved on the outer wall of the connecting rod 14. The two ends of the spring 15 are respectively matched with the two groups of annular plates 6. It should be explained that although the wedge block 13 rotates synchronously when the display screen body 1 is adjusted, firstly, the rotation angle of the general display screen body 1 is small. Secondly, the wedge block 13 is close to the center of the rotation of the display screen body 1, that is, the rotation amplitude is small. Therefore, when the display screen body 1 is adjusted in angle, the adjusting rod 11 is always located in the hole of the wedge block 13.

[0032] Reference Figure 1 , Figure 2 and Figure 6 The buffer portion includes multiple groups of elastic telescopic rods 17 fixedly connected to the side of the mounting seat 16 close to the display screen body 1, and a universal ball 18 is arranged at the end of the elastic telescopic rod 17 away from the mounting seat 16. A ball seat 20 is rotatably connected to the outer wall of the universal ball 18, and a protective plate 19 is fixedly connected to the multiple groups of ball seats 20. The protective plate 19 fits the display screen body 1, and the side of the mounting seat 16 away from the bracket 2 is convex. The mounting seat 16 is evenly provided with multiple groups of through holes, wherein the protective plate 19 can be made of soft material. The specific structure of the elastic telescopic rod 17 can refer to the technical solution in the prior art. Those skilled in the art can know that it will not be repeated here. The elastic telescopic rod 17 itself has a certain elasticity.

[0033] Reference Figure 1-Figure 3 , and also includes a plurality of groups of circular holes 3 and rectangular holes 4 opened on one side of the bracket 2 close to the display screen body 1, wherein a fixing bolt 5 is set between one group of circular holes 3 and rectangular holes 4 and the display screen body 1, wherein the circular holes 3 are used to position the display screen body 1, and the rectangular holes 4 are used to prevent the holes on the display screen body 1 from being misaligned, thereby improving the applicability of the device.

[0034] In the present invention, when installing the display screen body 1, firstly, the bracket 2 is installed on the display screen body 1 by means of the fixing bolts 5, and then the mounting base 16 is fixed to the wall by means of expansion screws, and then the display screen body 1 is hung on the wall by means of the cooperation between the buckle 8 and the mounting base 16; initially, the display screen body 1 is at the minimum angle, and when the angle of the display screen body 1 needs to be adjusted, the display screen body 1 is directly rotated upward, and at this time, the display screen body 1 drives the ratchet 9 to rotate, and during the upward rotation process, the ratchet 10 will not affect the rotation of the ratchet 9, and after the angle adjustment is completed, the display screen body 1 is released, and under the action of the ratchet 10, The ratchet 9 can be prevented from rotating in the opposite direction, thereby fixing the display screen body 1 and preventing it from loosening, thereby ensuring the stability of the display screen body 1 during use and making the operation relatively simple; when the display screen body 1 needs to be rotated downward, the push rod 12 is pressed inward, and the push rod 12 drives the wedge block 13 to move, and the ratchet 10 is driven to rotate through the adjusting rod 11, so that the ratchet 10 is disengaged from the ratchet 9, and then the display screen body 1 will rotate downward under the action of its own gravity, and in this process, the elastic telescopic rod 17 can adapt to the distance between the wall and the display screen body 1, so as to support and buffer the display screen body 1.

[0035] Although the present invention is disclosed through the above embodiments, the scope of the present invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the present invention.
