Description

Technical Field

[0001] The utility model relates to the technical field of display device protection, in particular to an anti-glare protection panel for a liquid crystal display screen. Background Art

[0002] Liquid crystal display screens are widely used in various scenarios such as outdoor advertising, industrial control, and vehicle-mounted devices. The display surface thereof is easily affected by external strong light reflection in terms of visibility, and meanwhile faces erosion risks such as collision, dust, and water vapor. Therefore, it is necessary to match with an anti-glare protection panel to ensure the use effect and service life. Most existing anti-glare protection panels realize the reflection suppression function through an anti-glare coating. The core installation position of the protection panel is the display surface (front side) of the liquid crystal display screen, and it needs to be closely attached to the screen display area without blocking the visible range, which is a functional panel directly covering the outermost layer of the screen.

[0003] Based on the above, the inventor found that there are the following problems: the existing traditional protection panels adopt installation methods such as screw fixing or sealant bonding fixing. Screw fixing requires tools to tighten one by one, which is cumbersome in operation and low in efficiency, and may damage the display screen due to screw slipping during disassembly; although sealant bonding fixing does not require tools, the viscosity of the sealant decreases after long-term use, causing the protection panel to loosen and fall off.

[0004] Therefore, in view of this, the present invention researches and improves the existing structure and deficiencies, and provides an anti-glare protection panel for liquid crystal display screens, so as to achieve the purpose of having more practical value. Summary of Utility Model

[0005] The purpose of the present utility model is to provide an anti-glare protection panel for a liquid crystal display screen, so as to solve the problems raised in the above background art.

[0006] In view of the above problems, the technical solution proposed by the present utility model is:

[0007] An anti-glare protection panel for a liquid crystal display screen, comprising a display screen, wherein an outer frame is arranged on the front side of the display screen, the outer frame is in a shape of a "loop", and an inner plate is installed inside the outer frame; first elastic strips are arranged on both sides of an outer wall of the outer frame, a first side block is installed on an opposite side of each of the two first elastic strips, the two first side blocks are arranged oppositely, and an outer wall of one end of each of the two first side blocks is in close contact with a back side of the display screen; second elastic strips are arranged on outer walls of two ends of the outer frame, a second side block is installed on an opposite side of each of the two second elastic strips, the two second side blocks are arranged oppositely, and an outer wall of one end of each of the two second side blocks is in close contact with the back side of the display screen.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the "U"-shaped outer frame provides a stable mounting carrier for the inner panel. At the same time, through the elastic tension of the first and second elastic strips, the first and second side blocks are driven to tightly adhere to the back of the display screen from both sides and ends, forming a two-way clamping and fixing structure. The assembly of the protective panel and the display screen can be completed without the need for screws or other tools, making installation convenient and without damaging the display screen itself.

[0009] Furthermore, each of the two first elastic strips has a first connecting seat installed at the end away from the first side block, and the two first connecting seats are respectively installed on both sides of the outer wall of the outer frame. Each of the two second elastic strips has a second connecting seat installed at the end away from the second side block, and the two second connecting seats are respectively installed on the outer walls at both ends of the outer frame.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the first connecting seat and the second connecting seat provide precise installation positioning for the first elastic strip and the second elastic strip, ensuring that the first elastic strip and the second elastic strip are firmly connected to the outer frame, and preventing the first elastic strip and the second elastic strip from falling off or shifting during long-term use.

[0011] Furthermore, both the first elastic strip and the second elastic strip are made of spring steel.

[0012] The beneficial effects of adopting the above-mentioned further solutions are that spring steel has excellent elastic recovery performance, can maintain stable tension after long-term clamping, and avoids clamping loosening due to elastic fatigue; it has high mechanical strength, wear resistance and corrosion resistance, can adapt to different use environments, and is not easily deformed by oxidation or external force, ensuring the long-term reliability of the elastic clamping structure.

[0013] Furthermore, the top and bottom surfaces of the first side block are each provided with a first side plate, and the outer walls of one end of the two first side plates are respectively fixedly connected to the back of the display screen. The two sides of the second side block are each provided with a second side plate, and the outer walls of one end of the two second side plates are respectively fixedly connected to the back of the display screen.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the first side plate and the second side plate respectively limit and fix the first side block and the second side block; when the protective panel is installed with the display screen, the first side block is aligned with the space formed by the two first side plates, and the second side block is aligned with the space formed by the two second side plates. Then, the protective panel is pushed towards the display screen. Since one side of the first side block and the second side block are inclined, the first side block and the second side block exert pressure on the outer wall of the display screen under the pushing action, causing the first elastic strip and the second elastic strip to deform. When the sealing gasket is attached to the front of the display screen and the first side block is located in the space formed by the two first side plates and the second side block is located in the space formed by the two second side plates, the first elastic strip and the second elastic strip return to their original state.

[0015] Furthermore, corner protectors are fitted at all four corners between the outer frame and the display screen. A second strong magnetic sheet is embedded in the inner wall of each corner protector near the outer frame. Mounting grooves are provided at all four corners of the front of the outer frame. A first strong magnetic sheet is installed in each mounting groove. The first and second strong magnetic sheets are magnetically connected. The inner wall of the corner protector is tightly fitted to the outer frame and the outer wall of the display screen.

[0016] The beneficial effects of adopting the above-mentioned further solution are that the magnetic attraction between the first and second strong magnetic sheets enables the corner protectors to be quickly installed and fixed, making the operation convenient and the disassembly flexible; the corner protectors provide targeted protection for the four corners of the display screen and the protective panel, preventing sharp edges from being damaged by collisions.

[0017] Furthermore, a sealing gasket is installed on the back of the outer frame, and the sealing gasket is tightly attached to the front of the display screen on the side away from the outer frame.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the sealing gasket fills the gap between the outer frame and the front of the display screen, forming a sealing barrier that effectively prevents dust, moisture and other impurities from entering, and avoids the display screen from getting damp or accumulating dust, thus affecting its use.

[0019] Furthermore, the outer frame is made of ABS plastic, and the inner panel is composed of an acrylic substrate and an anti-glare coating.

[0020] The beneficial effects of adopting the above-mentioned further solutions are that ABS plastic material is lightweight, high-strength, wear-resistant, and impact-resistant, which reduces the overall weight of the protective panel and provides reliable protection for the inner panel and display screen. It also has good processability and can be adapted to the production of outer frames for display screens of different sizes. The acrylic substrate has high light transmittance, which does not affect the display screen's image quality. The anti-glare coating on the surface can effectively scatter strong external light, reduce reflection interference, and improve the screen's visibility in strong light environments. At the same time, the anti-glare coating has wear-resistant and scratch-resistant properties, extending the service life of the inner panel.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: When the anti-glare protective panel for the LCD screen is installed with the screen, the first side block aligns with the space formed by the two first side plates, and the second side block aligns with the space formed by the two second side plates. Then, the protective panel is pushed towards the screen. Since one side of the first and second side blocks is inclined, the first and second side blocks exert pressure on the outer wall of the screen under the pushing action, causing the first and second elastic strips to deform. When the sealing gasket is attached to the front of the screen and the first side block is located within the space formed by the two first side plates, The second side block is located within the space formed by the two second side plates, and the first and second elastic strips are restored to their original positions. Through the elastic tension of the first and second elastic strips, the first and second side blocks are driven to tightly adhere to the back of the display screen from both sides and ends, forming a two-way clamping and fixing structure. The protective panel and the display screen can be assembled without the need for screws or other tools, making installation convenient and without damaging the display screen itself. The first and second side plates respectively limit and fix the first and second side blocks. The corner protectors provide targeted protection for the four corners of the display screen and the protective panel, preventing sharp corners from being damaged by impact.

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-5 , the present utility model provides a technical solution: an anti-glare protective panel for a liquid crystal display screen, comprising a display screen 1, a front face of the display screen 1 is provided with an outer frame 2, the outer frame 2 is in a "square ring" shape, and an inner plate 3 is installed inside the outer frame 2; first elastic strips 6 are respectively provided on both sides of an outer wall of the outer frame 2, a first side block 4 is installed on an opposite face of each of the two first elastic strips 6, the two first side blocks are arranged opposite to each other, and an outer wall of one end of each of the two first side blocks 4 is closely attached to a back face of the display screen 1; second elastic strips 10 are respectively provided on outer walls at both ends of the outer frame 2, a second side block 8 is installed on an opposite face of each of the two second elastic strips 10, the two second side blocks are arranged opposite to each other, and an outer wall of one end of each of the two second side blocks 8 is closely attached to the back face of the display screen 1; when the protective panel is installed on the display screen 1, the first side blocks 4 are aligned with the space formed by the two first side plates 5, the second side blocks 8 are aligned with the space formed by the two second side plates 9, and then the protective panel is pushed towards the display screen 1. Since one face of the first side blocks 4 and one face of the second side blocks 8 are inclined, under the pushing action, one face of the first side blocks 4 and one face of the second side blocks 8 generate pressure against the outer wall of the display screen 1, which causes the first elastic strips 6 and the second elastic strips 10 to deform. When the sealing rubber pad 12 is attached to the front face of the display screen 1, the first side blocks 4 are located in the space formed by the two first side plates 5, and the second side blocks 8 are located in the space formed by the two second side plates 9, the first elastic strips 6 and the second elastic strips 10 return to their original shapes; through the elastic tension of the first elastic strips 6 and the second elastic strips 10, the first side blocks 4 and the second side blocks 8 are driven to closely fit against the back face of the display screen 1 from both sides and both ends, forming a bidirectional clamping and fixing structure.

[0030] Wherein, first connecting seats 7 are respectively installed at ends of the two first elastic strips 6 away from the first side blocks 4, the two first connecting seats 7 are respectively installed on both sides of the outer wall of the outer frame 2, second connecting seats 11 are respectively installed at ends of the two second elastic strips 10 away from the second side blocks 8, and the two second connecting seats 11 are respectively installed on outer walls at both ends of the outer frame 2.

[0031] Wherein, both the first elastic strips 6 and the second elastic strips 10 are made of spring steel.

[0032] The first side block 4 has a first side plate 5 on its top and bottom surfaces. The outer walls of one end of the two first side plates 5 are fixedly connected to the back of the display screen 1. The second side block 8 has a second side plate 9 on both sides. The outer walls of one end of the two second side plates 9 are fixedly connected to the back of the display screen 1. The first side plate 5 and the second side plate 9 respectively limit and fix the first side block 4 and the second side block 8.

[0033] The outer frame 2 and the display screen 1 are provided with corner protectors 13 at the four corners. The inner wall of the corner protector 13 near the outer frame 2 is embedded with a second strong magnetic sheet. The four corners of the front of the outer frame 2 are provided with mounting grooves, and the first strong magnetic sheet 14 is installed in the mounting grooves. The first strong magnetic sheet 14 and the second strong magnetic sheet are magnetically connected. The inner wall of the corner protector 13 is tightly fitted with the outer frame 2 and the outer wall of the display screen 1. The corner protector 13 provides targeted protection for the four corners of the display screen 1 and the protective panel to avoid damage to the sharp edges and corners from collisions.

[0034] Among them, a sealing gasket 12 is installed on the back of the outer frame 2, and the sealing gasket 12 is tightly attached to the front of the display screen 1 on the side away from the outer frame 2.

[0035] The outer frame 2 is made of ABS plastic, and the inner panel 3 is composed of an acrylic substrate and an anti-glare coating.

[0036] Specifically, the working principle of this anti-glare protective panel for LCD screens is as follows: First, confirm that the first side plate 5 and the second side plate 9 on the back of the display screen 1 are installed in place. Then, align the outer frame 2 of the protective panel with the front of the display screen 1, so that the first side blocks 4 on both sides of the outer frame 2 correspond to the space formed by the two first side plates 5, and the second side blocks 8 at both ends of the outer frame 2 correspond to the space formed by the two second side plates 9. Slowly push the protective panel towards the display screen 1. Because the contact surfaces of the first side blocks 4 and the second side blocks 8 are inclined, the inclined surfaces are squeezed against the outer wall of the display screen 1 during the pushing process, causing the first elastic strip 6 and the second elastic strip 10 to undergo elastic deformation. The first side blocks 4 and the second side blocks 8 open outwards to avoid the display screen 1. Continue pushing the protective panel until the sealing gasket 12 on the back of the outer frame 2 is completely attached to the front of the display screen 1. At this time, the first side block 4 enters the space formed by the two first side plates 5, and the second side block 8 enters the space formed by the two second side plates 9. The first elastic strip 6 and the second elastic strip 10 lose the squeezing force and return to their original shape, using their own elastic tension to drive the first side... Block 4 and the second side block 8 are tightly fitted to the back of the display screen 1, forming a two-way clamping fixation, completing the rapid assembly of the protective panel and the display screen 1 without the need for screws or other tools. Then, the four corner protectors 13 are respectively fitted onto the four corners of the outer frame 2 and the display screen 1. The second strong magnetic sheet on the inner wall of the corner protector 13 magnetically attaches to the first strong magnetic sheet 14 in the four corner mounting slots of the outer frame 2, tightly wrapping the four corners for targeted protection. During use, the anti-glare coating of the inner panel 3 can scatter strong external light, reducing reflective interference and improving the display screen 1's performance. Visibility in strong light environments; sealing gasket 12 prevents dust and moisture from entering, protecting the display surface of display screen 1; ABS material outer frame 2, in conjunction with spring steel elastic strip, can buffer minor external impacts and prevent damage to display screen 1; if the protective panel needs to be removed, first remove the four corner protectors 13, then bend the first elastic strip 6 and the second elastic strip 10 outwards to disengage the first side block 4 and the second side block 8 from the limit of the first side plate 5 and the second side plate 9, and the protective panel can be easily removed from display screen 1. The disassembly is convenient and does not damage the display screen 1 body.

[0037] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
