Description

Technical Field

[0001] The utility model relates to the technical field of light guide plate components, in particular to an LED light guide plate component. Background Art

[0002] Light guide plates can transform point and line light sources into surface light sources. Due to their ultra-thinness, light uniformity, high efficiency and energy saving, stability and durability, they are now increasingly being used in display screens, devices and lighting fixtures. Light guide plate lighting components usually use LEDs as light sources. The light from the light source is introduced into the light guide plate, transmitted inside the light guide plate, and finally transmitted from the light-emitting surface of the light guide plate to everywhere through the high-conductivity light guide points.

[0003] Existing light guide plates and light guide plate assemblies are usually connected by glue. When the light guide plate is damaged, it needs to be replaced as a whole, and the replacement cost is high. Therefore, an LED light guide plate assembly is needed that can not only fix the light guide plate but also facilitate disassembly and replacement of the light guide plate. Utility Model Content

[0004] To this end, the utility model provides an LED light guide plate assembly, which facilitates the disassembly, assembly and replacement of the light guide plate body to solve the problem that the light guide plate needs to be replaced as a whole after being damaged, which results in high replacement costs.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an LED light guide plate assembly, comprising a light guide plate assembly, the light guide plate assembly comprising a light guide plate connecting frame, both ends of the light guide plate connecting frame are provided with fixed inclined plates, a light guide plate fixing unit is provided inside the light guide plate connecting frame, the light guide plate fixing unit comprises a tension adjustment bolt, a fixing screw sleeve is provided on the outside of the tension adjustment bolt, a movable frame is fixedly provided at one end of the fixing screw sleeve, side panels are fixedly provided at both ends of the movable frame, limiting grooves are provided inside the two side panels, two clamping components are provided inside the two movable frames, the clamping components comprise a clamping plate, connecting blocks are fixedly provided at both ends of the clamping plate, movable inclined plates are fixedly provided at one end of the two connecting blocks, and a light guide plate body is provided between the two clamping plates.

[0006] Preferably, the tension adjustment bolt passes through the light guide plate connecting frame and is connected to the light guide plate connecting frame via a bearing.

[0007] Preferably, one end of the tension adjustment bolt extends into the interior of the fixing screw sleeve and is threadedly connected to the fixing screw sleeve.

[0008] Preferably, the movable frame is arranged inside the light guide plate connecting frame and is slidably connected to the light guide plate connecting frame.

[0009] Preferably, a light strip groove is provided inside the movable frame, and an LED light strip is fixed inside the light strip groove.

[0010] Preferably, the clamping plate is arranged inside the movable frame and is slidably connected to the movable frame.

[0011] Preferably, the connecting block passes through the limiting groove and is slidably connected to the limiting groove.

[0012] Preferably, the movable inclined plate is in contact with the fixed inclined plate and is slidably connected to the fixed inclined plate.

[0013] The utility model embodiment has the following advantages:

[0014] 1. When the movable frame moves, the limit grooves on the side plates on both sides drive the connection block to move, and then the light guide plate body is driven to move through the clamping plate. When the connection block moves, the movable inclined plate slides along the fixed inclined plate toward the lower end of the fixed inclined plate, thereby weakening the clamping force of the clamping plate on the light guide plate body, making it easier to remove the light guide plate body from the two clamping plates, thereby facilitating the separate replacement of the light guide plate body, preventing the overall replacement of the light guide plate assembly during replacement, and reducing the replacement cost;

[0015] 2. Insert the light guide plate body between the two clamping plates and make one side of the light guide plate body contact with the movable frame and apply a slight thrust. At this time, rotate the tension adjustment bolt clockwise to make the fixed screw sleeve drive the movable frame to slide. The sliding of the movable frame causes the movable inclined plate to slide toward the high end of the fixed inclined plate, reducing the distance between the two movable inclined plates, thereby tightening and clamping the light guide plate body in the middle to facilitate installation.

[0026] In this embodiment, in order to facilitate the unit replacement of the light guide plate body 3, the limit grooves 25 on the side plates 24 on both sides drive the connection block 262 to move when the movable frame 23 moves, and then the light guide plate body 3 is driven to move through the clamping plate 261. When the connection block 262 moves, the movable inclined plate 263 slides along the fixed inclined plate 12 toward the lower end of the fixed inclined plate 12, so that the clamping force of the clamping plate 261 on the light guide plate body 3 is weakened, so that the light guide plate body 3 is taken out from the two clamping plates 261, so that the light guide plate body 3 can be replaced separately, and the overall replacement of the light guide plate assembly 1 is prevented during replacement, thereby reducing the replacement cost.

[0027] Among them, in order to achieve the purpose of controlling the movement of the movable frame 23, the present device adopts the following technical solutions: the tension adjustment bolt 21 penetrates the light guide plate connecting frame 11 and is connected to the light guide plate connecting frame 11 through a bearing, one end of the tension adjustment bolt 21 extends into the interior of the fixed screw sleeve 22 and is connected to the fixed screw sleeve 22 through a thread, the movable frame 23 is arranged inside the light guide plate connecting frame 11 and is slidably connected to the light guide plate connecting frame 11, a light belt groove is opened inside the movable frame 23, and an LED light belt 27 is fixed inside the light belt groove, by rotating the tension adjustment bolt 21, the tension adjustment bolt 21 rotates and cooperates with the thread of the fixed screw sleeve 22, so that the fixed screw sleeve 22 drives the movable frame 23 to move, so as to achieve the purpose of controlling whether the clamping component 26 fixes the light guide plate body 3;

[0028] Among them, in order to achieve the purpose of clamping the light guide plate body 3 with the two clamping plates 261, the present device is implemented by the following technical scheme: the clamping plate 261 is arranged inside the movable frame 23 and is slidably connected to the movable frame 23, the connecting block 262 passes through the limiting groove 25 and is slidably connected to the limiting groove 25, the movable inclined plate 263 contacts the fixed inclined plate 12 and is slidably connected to the fixed inclined plate 12, the movable frame 23 moves so that the movable inclined plate 263 slides along the fixed inclined plate 12 toward the high end of the fixed inclined plate 12, so that the distance between the two movable inclined plates 263 is reduced, thereby fastening and clamping the light guide plate body 3 in the middle.

The movable frame 23 moves through the limit grooves 25 on the side plates 24 on both sides to drive the connecting block 262 to move, and then drives the light guide plate body 3 to move through the clamping plate 261. When the connecting block 262 moves, the movable inclined plate 263 slides along the fixed inclined plate 12 toward the lower end of the fixed inclined plate 12, so that the clamping plate The clamping force of 261 on the light guide plate body 3 is weakened, which makes it easy to take the light guide plate body 3 out of the two clamping plates 261, thereby facilitating the individual replacement of the light guide plate body 3 and preventing the overall replacement of the light guide plate assembly 1 during replacement, thereby reducing the replacement cost. Similarly, when the light guide plate body 3 needs to be installed, the light guide plate body 3 is inserted between the two clamping plates 261 and one side of the light guide plate body 3 is in contact with the movable frame 23 and a slight thrust is applied. At this time, the tension adjustment bolt 21 is rotated clockwise to make the fixed screw sleeve 22 drive the movable frame 23 to slide. The sliding of the movable frame 23 causes the movable inclined plate 263 to slide toward the high end of the fixed inclined plate 12, so that the distance between the two movable inclined plates 263 is reduced, thereby tightening and clamping the light guide plate body 3 in the middle to achieve the purpose of easy installation.
