Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to an anti-scratch LCD display screen. Background Art

[0002] LCD displays are widely used in a variety of electronic devices, such as mobile phones, tablets, TVs, and computer monitors. LCD screens are favored for their fine display effects, thin designs, and energy efficiency. However, a major weakness of LCD screens is that their surfaces are easily scratched and damaged. Scratches not only affect the display effect, but may also make the screen more susceptible to breakage. Therefore, it is particularly important to protect LCD screens from scratches.

[0003] Most LCD screen protection solutions on the market currently use additional screen protective films or tempered glass. Although these protective measures can reduce scratches to a certain extent, they have some shortcomings. First, the additional screen protective film or tempered glass may affect the touch sensitivity and display effect. Second, the installation and replacement process of these protective measures is cumbersome, and it is easy to generate bubbles and dust, affecting the appearance and user experience. In addition, once the protective film or glass is broken, the replacement process may also cause additional damage to the LCD screen.

[0004] Therefore, a new type of LCD display screen protection technology is needed, which can effectively prevent scratches and damages, and does not affect the display effect and touch function of the screen, while ensuring that the installation and replacement process is simple and safe. The emergence of this technology will provide a better solution for the use and maintenance of LCD screens, thereby extending their service life and improving user experience. To this end, the utility model proposes an anti-scratch LCD display screen to solve the above problems. Utility Model Content

[0005] In order to overcome the defects of the prior art, the purpose of the present invention is to provide an anti-scratch LCD display screen to solve the problems raised in the above background technology.

[0006] To achieve the above object, the technical solution of the utility model is implemented as follows: an anti-scratch LCD display screen, comprising a PCB board, an LCD screen body, an anti-scratch protection plate and a connection and installation component, wherein the LCD screen body is fixedly installed on one side of the PCB board, the LCD screen body is provided with an anti-scratch protection plate at one end away from the PCB board, and the connection and installation component is provided between the PCB board and the anti-scratch protection plate;

[0007] The connection and installation assembly includes a hollow cylinder, a through groove, a strip slide groove, an annular slide groove, a rotating rod, a bearing seat, a knob and a locking block. The connection and installation assembly has four groups. The hollow cylinder is fixed around the anti-scratch protection plate. A through groove is provided in the hollow cylinder. The upper and lower sides of the through groove are respectively connected with the strip slide groove. The other end of the strip slide groove is vertically connected with the annular slide groove. The annular slide groove is provided on the annular surface of the through groove. The annular slide groove is also connected with the through groove. The bearing seat is fixed around the PCB board. One end of the bearing seat is rotatably connected with a rotating rod. A knob is fixed on the rotating rod. The other end of the rotating rod passes into the through groove of the hollow cylinder. Locking blocks are respectively fixed at the upper and lower ends of the rotating rod.

[0008] Preferably, one end of the through groove is communicated with the outside.

[0009] Preferably, one end of the strip-shaped slide groove is also connected to the outside.

[0010] Preferably, the knob is provided with anti-slip textures.

[0011] Preferably, the locking block is slidably placed in a strip-shaped slide groove or an annular slide groove.

[0012] Preferably, the locking block is adapted in shape and size to the strip-shaped sliding groove and the annular sliding groove.

[0013] Preferably, the anti-scratch protection plate comprises two plastic films and tempered glass, and the tempered glass is bonded between the two plastic films.

[0014] The beneficial effects of the utility model are embodied in:

[0015] Quick installation and removal: The design of connecting the installation components allows the anti-scratch protection plate to be quickly and easily installed or removed. When assembly is required, just bring the anti-scratch protection plate close to the LCD screen body, and then align the through slot and the rotating rod of the hollow cylinder so that the rotating rod passes into the through slot. The locking block slides into the bar slot in advance until the locking block slides into the annular slot, and then the locking block is screwed into the annular slot by rotating the knob to achieve quick locking. This design simplifies the installation process of the traditional display screen protection plate, saving time and labor.

[0016] Excellent anti-scratch screen protection effect: The anti-scratch protection plate consists of two plastic films and tempered glass. The tempered glass is bonded between the two plastic films. This structure not only enhances the anti-scratch ability of the anti-scratch protection plate, but also retains the clear display effect of the LCD display. The use of tempered glass also increases the impact resistance of the protection plate, further protecting the LCD screen from damage by external physical factors.

[0017] In general, the design of this anti-scratch LCD display is comprehensive, which not only ensures the safety protection of the LCD screen, but also provides a fast and stable installation method, greatly improving the convenience and practicality of use. BRIEF DESCRIPTION OF THE DRAWINGS
