Description

Technical Field

[0001] This utility model relates to the field of light box technology, specifically to a sliding LED light strip mounting structure for an ultra-thin pull-out light box. Background Technology

[0002] Ultra-thin pull-out light boxes are widely used in commercial advertising, interior decoration and other scenarios due to their compact size and good display effect. As the core light-emitting component of ultra-thin pull-out light boxes, the rationality of the installation structure of LED light strips directly affects the light-emitting effect, ease of assembly and later maintenance efficiency of the light box.

[0003] Most existing ultra-thin pull-out light boxes use fixed installation for their LED light strips. The light strips are directly fixed to the light box frame by screws or adhesive. This installation structure makes it impossible to adjust the light strips during installation. When there is a slight dimensional deviation in the light strip or when it is necessary to adjust the light-emitting area, the position of the light strip cannot be adjusted by sliding, resulting in uneven light emission from the light guide plate in the light box. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a sliding LED light strip installation structure for ultra-thin pull-out light boxes, which effectively solves the problem that the LED light strips in existing ultra-thin pull-out light boxes cannot be adjusted during installation, resulting in uneven light emission from the light guide plate in the light box.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a sliding LED light strip installation structure for an ultra-thin pull-out light box, including two light box frames, a light guide plate and tempered glass. The two light box frames are arranged on both sides of the light guide plate, and each of the two light box frames is provided with a limiting plate that clamps on both sides of the tempered glass.

[0009] Each of the two light box frames has a mounting groove on the side near the light guide plate. A light strip assembly is slidably mounted in the mounting groove. The side of the light strip assembly facing the light box frame has a fixedly connected positioning strip. The side of the positioning strip near the light box frame has a scale for adjusting the position of the light strip assembly. The side of the light box frame near the scale has a sliding groove that is slidably connected to the positioning strip. The positioning strip is embedded in the sliding groove and forms a sliding fit with the sliding groove. An observation window is opened through the light box frame on the side of the sliding groove away from the positioning strip.

[0010] Furthermore, one end of the mounting groove is provided with a disassembly buckle plate. The buckle plate has a U-shaped structure and its two ends are respectively engaged with the ends of the light box frame. The inner sidewall of the buckle plate is attached to the end of the light strip assembly to limit the light strip assembly from shaking in the mounting groove.

[0011] Furthermore, a canvas cavity is formed between the light guide plate and the tempered glass along the thickness direction. Grooves are provided on the light box frame along the length direction on both sides of the canvas cavity. The openings of the two grooves face the canvas cavity and the groove diameter is adapted to the thickness of the canvas. The grooves and the canvas cavity are connected to form a sliding insertion channel for the canvas.

[0012] Furthermore, the light guide plate has two elongated fixing blocks on the side away from the tempered glass. The two fixing blocks are symmetrically distributed along the width direction of the light guide plate and connected to the light box frame. The fixing blocks have fixing grooves on the side away from the light guide plate. The sides of the two fixing blocks that are away from each other are fixedly connected to the light box frame.

[0013] Furthermore, a fixing plate and a cover plate are respectively assembled at both ends of the two fixing blocks along the length direction. The fixing plate and the cover plate are both long strips and cover the ends of the two fixing blocks. Each fixing plate and the cover plate has a connecting block adapted to the fixing groove on the side facing the fixing block. The connecting block is embedded in the fixing groove and fixed by screws.

[0014] Furthermore, the cover plate has an opening groove in the middle along the length direction. The cross-sectional profile of the opening groove is consistent with the cross-sectional profile of the canvas cavity, and the length of the opening groove is adapted to the length of the canvas cavity. The opening groove is connected to the canvas cavity and is used to insert the canvas into the canvas cavity.

[0015] Furthermore, each of the two limiting plates has a limiting groove along its length on one side opposite to the other. The limiting groove is provided with a limiting strip that is slidably fitted. The limiting strip has an anti-slip texture on the side facing the tempered glass, and this side is in close contact with the side edge of the tempered glass.

[0016] Furthermore, multiple threaded holes are evenly distributed along the length of the two limiting plates on the side away from each other. Each threaded hole is threaded with a fixing bolt. The inner end of the fixing bolt passes through the limiting plate and abuts against the side of the limiting strip. The fixing bolt is used to adjust the limiting strip to hold the tempered glass and prevent it from shifting.

[0017] Beneficial effects

[0018] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0019] This utility model features a light strip assembly that slides between the mounting groove and the light box frame. With the guidance of the positioning strip and the sliding groove, the light strip assembly slides smoothly. The scale on the positioning strip works in conjunction with the observation window of the light box frame, allowing operators to intuitively read the position parameters of the light strip and make precise adjustments. This effectively adjusts the light guiding requirements and the size deviation of the light guide plate, thereby improving the uniformity of light emission in the light box.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example: A sliding LED light strip mounting structure for an ultra-thin pull-out lightbox, such as... Figure 1-6 As shown, it includes two light box frames 1, a light guide plate 4 and tempered glass 5. The two light box frames 1 are arranged on both sides of the light guide plate 4, and each of the two light box frames 1 is provided with a limiting plate 2 that clamps on both sides of the tempered glass 5.

[0031] Each of the two light box frames 1 has a mounting groove 102 on the side near the light guide plate 4. A light strip assembly 3 is slidably mounted in the mounting groove 102. The side of the light strip assembly 3 facing the light box frame 1 has a fixedly connected positioning strip 31. The side of the positioning strip 31 near the light box frame 1 is engraved with a scale 32 for adjusting the position of the light strip assembly 3. The side of the light box frame 1 near the scale 32 is provided with a sliding groove 103 that is slidably connected to the positioning strip 31. The positioning strip 31 is embedded in the sliding groove 103 and forms a sliding fit with the sliding groove 103. The side of the sliding groove 103 away from the positioning strip 31 has an observation window 105 that penetrates the light box frame 1.

[0032] In this utility model, the light strip assembly 3 is slidably assembled with the light box frame 1 through the mounting groove 102. With the guidance of the positioning strip 31 and the slide groove 103, the light strip assembly 3 can slide smoothly. The scale 32 on the positioning strip 31 cooperates with the observation window 105 of the light box frame 1, so that the operator can intuitively read the position parameters of the light strip, achieve precise adjustment, effectively adjust the light guide requirements and the size deviation of the light guide plate 4, and improve the uniformity of light emission of the light box.

[0033] Furthermore, one end of the mounting groove 102 is provided with a disassembly buckle 14. The buckle 14 has a U-shaped structure and its two ends are respectively engaged with the ends of the light box frame 1. The inner sidewall of the buckle 14 is attached to the end of the light strip assembly 3 to limit the light strip assembly 3 from shaking in the mounting groove 102.

[0034] The U-shaped detachable buckle plate 14 is fixed to the end of the mounting groove 102 by snap-fitting and fits tightly with the end of the light strip assembly 3. This effectively limits the shaking of the light strip assembly 3 and improves the stability of the fixation. When disassembling, only the buckle plate 14 needs to be removed to pull out the light strip assembly 3. There is no need to disassemble the entire light box frame 1, which greatly simplifies the maintenance and replacement process.

[0035] Furthermore, a canvas cavity 101 is formed between the light guide plate 4 and the tempered glass 5 along the thickness direction. Grooves 104 are provided on the light box frame 1 on both sides of the canvas cavity 101 along the length direction. The openings of the two grooves 104 face the canvas cavity 101 and the groove diameter is adapted to the thickness of the canvas. The grooves 104 and the canvas cavity 101 are connected to form a sliding insertion channel for the canvas.

[0036] Furthermore, the light guide plate 4 has two elongated fixing blocks 13 on the side away from the tempered glass 5. The two fixing blocks 13 are symmetrically distributed along the width direction of the light guide plate 4 and connected to the light box frame 1. The fixing blocks 13 have fixing grooves 1301 on the side away from the light guide plate 4. The sides of the two fixing blocks 13 that are away from each other are fixedly connected to the light box frame 1.

[0037] Furthermore, a fixing plate 11 and a cover plate 12 are respectively assembled at both ends of the two fixing blocks 13 along the length direction. The fixing plate 11 and the cover plate 12 are both long strips and cover the ends of the two fixing blocks 13. The fixing plate 11 and the cover plate 12 are provided with a connecting block 121 adapted to the fixing groove 1301 on the side facing the fixing block 13. The connecting block 121 is embedded in the fixing groove 1301 and fixed by screws.

[0038] Furthermore, the cover plate 12 has an opening groove 1201 in the middle along the length direction. The cross-sectional profile of the opening groove 1201 is consistent with the cross-sectional profile of the canvas cavity 101, and the length of the opening groove 1201 is adapted to the length of the canvas cavity 101. The opening groove 1201 is connected to the canvas cavity 101 and is used to insert the canvas into the canvas cavity 101.

[0039] Then, the canvas cavity 101 formed between the light guide plate 4 and the tempered glass 5, together with the groove 104 of the light box frame 1, forms a complete sliding insertion channel. The opening groove 1201 of the cover plate 12 is connected to the canvas cavity 101, so that the canvas can be directly inserted into the canvas cavity 101 through the opening groove 1201 and the groove 104, realizing the quick insertion and removal of the canvas without disassembling the light box components, thus improving the replacement efficiency.

[0040] Furthermore, each of the two limiting plates 2 has a limiting groove 201 along its length on one side opposite to the other. The limiting groove 201 is provided with a limiting strip 21 that is slidably fitted. The limiting strip 21 has anti-slip texture on the side facing the tempered glass 5, and this side is in close contact with the side edge of the tempered glass 5.

[0041] Furthermore, multiple threaded holes are evenly distributed along the length direction on the side of the two limiting plates 2 that are far apart from each other. Each threaded hole is threaded with a fixing bolt 22. The inner end of the fixing bolt 22 passes through the limiting plate 2 and abuts against the side of the limiting strip 21. The fixing bolt 22 is used to adjust the limiting strip 21 to clamp the tempered glass 5 to prevent it from shifting.

[0042] During assembly, the first step is to install and position the light strip assembly 3. Positioning strips 31 on one side of the two light strip assemblies 3 are inserted into the corresponding grooves 103 of the light box frame 1. The light strip assemblies 3 are then slid into the mounting slots 102 of the two light box frames 1. The scale 32 of the positioning strips 31 is read through the observation window 105 on the light box frame 1. After precisely adjusting the light strip assembly 3 to the appropriate light-emitting position, the U-shaped buckle 14 is snapped onto the end of the mounting slot 102. The inner wall of the buckle 14 fits against the end of the light strip assembly 3 to achieve a limiting and fixing effect, preventing the light strip assembly 3 from shaking. Next, the main frame of the light box is assembled. The fixing plate 11 is inserted into the fixing groove 1301 at one end of the fixing block 13 via the connecting block 121 on one side. The fixing plate 11 and the fixing block 13 are connected by screw fastening. The light guide plate 4, the light box frame 1, and the fixing block 13 form a stable main frame structure. Then, the tempered glass 5 is fixed by placing it in the clamping space formed by the two limiting plates 2. The fixing bolts 22 are tightened along the threaded holes on the limiting plates 2. The inner end of the fixing bolts 22 pushes the limiting strip 21 to move towards the tempered glass 5 until the side of the limiting strip 21 with anti-slip texture is tightly attached to the side edge of the tempered glass 5, thus achieving stable clamping of the tempered glass 5. Finally, the canvas is installed and powered on: the canvas to be displayed is introduced through the opening slot 1201 in the middle of the cover plate 12 and slid into the canvas cavity 101 between the light guide plate 4 and the tempered glass 5 through the groove 104 of the light box frame 1. After the canvas is assembled, the light strip assembly 3 is connected to the power supply to realize the normal light display of the light box.
