Description

Technical Field

[0001] The utility model relates to a display device, in particular to a light guide plate display device. Background Art

[0002] A light guide plate display device is a display device that uses light guide plate technology to improve the display effect. The light guide plate is a transparent material with excellent optical properties that can effectively transmit light and distribute it evenly over the entire display surface. In a display device, the light guide plate is usually placed behind the display screen to improve the display effect, enhance brightness and uniformity, and reduce light leakage and reflection.

[0003] The existing light guide plate is generally attached to the back plate by screws or glue. During use, if the screws are tightened, the light guide plate will be pressed, causing the connection position of the light guide plate to be easily damaged. If it is connected by glue, it will be difficult to remove the light guide plate when it needs to be repaired. Summary of the invention

[0004] The utility model aims to solve the problem that the existing light guide plate installation method easily causes damage to the light guide plate and is difficult to remove the light guide plate.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A light guide plate display device comprises a display housing and a light guide plate, wherein a retaining ring is arranged inside the display housing, the surface of the retaining ring of the light guide plate is movable, and then a clamping assembly is arranged on the inner wall of the display housing, a pressing frame is movably fitted on a side of the light guide plate away from the retaining ring, the pressing frame is movable inside the display housing, and the clamping assembly is clamped on a side of the pressing frame away from the light guide plate.

[0007] Preferably, a positioning slot is provided on the side of the light guide plate, and a positioning column is fixed on the surface of the retaining ring at a position corresponding to the positioning slot, and the positioning column is clamped inside the positioning slot.

[0008] Preferably, the positioning column is a conical column.

[0009] Preferably, the side surface of the pressing frame is provided with an extrusion groove, and the position and number of the extrusion groove match the position and number of the positioning slots.

[0010] Preferably: the clamping assembly includes a groove, inside which a spring and a clamping block are movable, one end of the spring is clamped on the inner wall of the groove, the other end of the spring is movably connected to one end of the clamping block, and the other end of the clamping block extends out of the groove and is clamped on the surface of the pressure frame.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By setting a pressing frame and a clamping assembly, the pressing frame presses the light guide plate to make it fit on the retaining ring, and then the clamping assembly clamps the frame to stabilize the pressing frame, thereby stabilizing the light guide plate through the pressing frame, thereby achieving the effect of pressing the light guide plate to stabilize it and reducing damage to the light baffle plate. The light baffle plate can be easily removed through the clamping assembly, which solves the problem that the existing light guide plate installation method easily causes damage to the light guide plate and is difficult to remove the light guide plate.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] See also Figures 1 to 3 In an embodiment of the utility model, a light guide plate display device includes a display housing 1 and a light guide plate 2, a retaining ring 3 is arranged inside the display housing 1, a surface of the movable retaining ring 3 of the light guide plate 2, and a positioning slot 6 is opened on the side of the light guide plate 2, and a positioning column 7 is fixed on the surface of the retaining ring 3 corresponding to the position of the positioning slot 6, the positioning column 7 is stuck in the inside of the positioning slot 6, and the positioning column 7 is a conical column, so that the light guide plate 2 can be conveniently placed on the retaining ring 3, and the light guide plate 2 can be positioned after being slowly guided by the positioning column 7.

[0019] A clamping assembly 4 is provided on the inner wall of the display housing 1, and a pressing frame 5 is movably attached to the side of the light guide plate 2 away from the retaining ring 3, and an extrusion groove 8 is provided on the side of the pressing frame 5. Figure 3As shown, the extrusion groove 8 can squeeze the card block 11 through the extrusion groove 8 when the pressing frame 5 is placed, so that the card block 11 shrinks into the groove 9 and compresses the spring 10. The position and number of the extrusion groove 8 match the position and number of the positioning card slots 6. The pressing frame 5 moves inside the display housing 1. The matching of the position and number can well stabilize the light guide plate 2 and the pressing frame 5, and the clamping component 4 is clamped on a side of the pressing frame 5 away from the light guide plate 2. The clamping component 4 includes a groove 9, and the spring 10 and the card block 11 are respectively movable inside the groove 9. One end of the spring 10 is clamped in the groove 9 On the inner wall, the other end of the spring 10 is movably connected with one end of the card block 11, and the other end of the card block 11 extends out of the groove 9 and is stuck on the surface of the pressing frame 5. When the pressing frame 5 is pressed on the light guide plate 2, the spring 10 squeezes the card block 11 to make it extend out of the groove 9 and be stuck on the surface of the pressing frame 5 to stabilize the pressing frame 5, and then stabilize the light guide plate 2. In this way, the light guide plate 2 can be limited well, and it is not easy to damage the light guide plate 2 like a screw. The card-connected placement also makes it convenient to move the card block 11 to remove the pressing frame 5, and then it is convenient to remove the light guide plate 2 for its repair and maintenance.
