Description
Technical Field
[0001] This utility model relates to the field of assembly frames, and in particular to an assembly frame for LED illuminated letters. Background Technology
[0002] LED illuminated signs are a common advertising and signage tool with many advantages such as high brightness, low energy consumption, and long lifespan. They are widely used in various fields such as commercial venues and public facilities. With the continuous growth and diversification of market demand, the requirements for the assembly methods and assembly frames of LED illuminated signs are also getting higher and higher.
[0003] In existing LED illuminated sign assembly technology, traditional assembly methods often rely on manual operation and simple clamps for fixing. This method is not only inefficient, but also relatively rigid when fixing the illuminated signs, which can easily damage them. This problem is particularly prominent in situations where the signs need to be frequently adjusted or replaced. Secondly, the existing assembly frame structure is relatively simple and lacks effective limiting functions. During use, the illuminated signs are easily affected by external forces and may move or loosen, reducing their stability and lifespan. To solve the above problems, we propose an LED illuminated sign assembly frame. Utility Model Content
[0004] The main purpose of this utility model is to provide an assembly frame for LED illuminated letters, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An assembly frame for LED illuminated letters includes a housing with a cover mounted on the top. A first motor is located at the front end of the housing, and a double-ended bidirectional lead screw is fixedly connected to the output end of the first motor. The double-ended bidirectional lead screw is rotatably connected to the housing. A first clamping assembly and a second clamping assembly are threadedly connected to the outer side of the double-ended bidirectional lead screw. Multiple connecting posts are provided on both the first and second clamping assemblies. Illuminated letter bodies are fixedly connected to the upper ends of the multiple connecting posts. The multiple illuminated letter bodies are located above the cover. The illuminated letter bodies closer to the front end form one group, and the illuminated letter bodies closer to the rear end form another group. Limiting components are provided at the ends of the two groups of illuminated letter bodies that are far apart from each other.
[0007] Preferably, both the first clamping assembly and the second clamping assembly include a first clamping plate and a second clamping plate. The first clamping plate and the second clamping plate are respectively threaded to the outside of the double-ended bidirectional lead screw. A plurality of first anti-slip pads are fixedly connected to the end of the first clamping plate that is close to the second clamping plate. A plurality of second anti-slip pads are fixedly connected to the end of the second clamping plate that is close to the first clamping plate. The plurality of connecting posts are respectively disposed on the inner side of the corresponding first anti-slip pads and second anti-slip pads.
[0008] Preferably, a guide rod is fixedly connected to the inner side of the box, and the first clamping plate and the second clamping plate are slidably connected to the outer side of the guide rod.
[0009] Preferably, a first upright plate and a second upright plate are fixedly connected to the upper end of the box cover, and a rotating rod is rotatably connected to the outer side of the first upright plate and the second upright plate. The front end of the rotating rod is fixedly connected to the output end of a second motor, and the second motor is fixedly installed on the upper end of the box cover.
[0010] Preferably, the limiting assembly includes a main gear, the inner side of which is fixedly connected to the outer side of the rotating rod. A chain is meshed on the outer side of the main gear, and a plurality of driven gears corresponding to the connecting post are meshed on the inner side of the chain. The plurality of driven gears are rotatably connected to the corresponding first and second upright plates, respectively. A limiting screw is threadedly connected to the inner side of the driven gear. A limiting hole corresponding to the limiting screw is opened on the outer side of the connecting post, and the limiting screw is located on the inner side of the connecting post.
[0011] Preferably, a sliding groove is provided on the outer side of the limiting screw, and a slider adapted to the sliding groove is fixedly connected to the first and second upright plates.
[0012] Preferably, a mounting plate is fixedly connected to the lower end of the first motor, and the mounting plate is fixedly installed at the front end of the housing.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The assembly frame for LED illuminated letters inserts the connecting posts connected to multiple illuminated letter bodies into the inside of the box cover. Then, the first motor is started, and its output end drives the double-headed bidirectional lead screw to rotate. Under the guidance of the guide rod, the first clamping plate and the second clamping plate in the first clamping assembly and the second clamping assembly will move smoothly towards each other. Through the buffering effect of the first anti-slip pad and the second anti-slip pad, the connecting posts can be initially fixed.
[0015] 2. This LED illuminated letter assembly frame uses the output of a second motor to drive a rotating rod to rotate. The two main gears fixed on the rotating rod rotate accordingly, which in turn drives the chain belt that meshes with them to rotate. The rotation of the chain belt drives multiple driven gears to rotate synchronously. Through the rotation of the driven gears, the limiting screw can be moved closer to the connecting column, so that the limiting screw slides into the limiting hole opened on the outside of the connecting column, thereby further limiting and fixing the connecting column and effectively preventing its movement.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figure 1-7 As shown, an assembly frame for LED illuminated letters includes a housing 1, a cover 2 mounted on the upper end of the housing 1, a first motor 4 at the front end of the housing 1, a double-headed bidirectional lead screw 5 fixedly connected to the output end of the first motor 4, the double-headed bidirectional lead screw 5 being rotatably connected to the housing 1, a first clamping assembly 7 and a second clamping assembly 8 being threadedly connected to the outer side of the double-headed bidirectional lead screw 5, a plurality of connecting posts 13 being provided on both the first clamping assembly 7 and the second clamping assembly 8, and an illuminated letter body 14 being fixedly connected to the upper end of each of the plurality of connecting posts 13, the plurality of illuminated letter bodies 14 being located above the cover 2, the plurality of illuminated letter bodies 14 near the front end forming one group, the plurality of illuminated letter bodies 14 near the rear end forming another group, and a limit component being provided at the far ends of both groups of illuminated letter bodies 14.
[0026] In this embodiment, both the first clamping assembly 7 and the second clamping assembly 8 include a first clamping plate 9 and a second clamping plate 10. The first clamping plate 9 and the second clamping plate 10 are respectively threaded to the outside of the double-ended bidirectional lead screw 5. A plurality of first anti-slip pads 11 are fixedly connected to the end of the first clamping plate 9 that is close to the second clamping plate 10. A plurality of second anti-slip pads 12 are fixedly connected to the end of the second clamping plate 10 that is close to the first clamping plate 9. A plurality of connecting posts 13 are respectively disposed on the inner side of the corresponding first anti-slip pads 11 and second anti-slip pads 12. A guide rod 6 is fixedly connected to the inner side of the housing 1. The first clamping plate 9 and the second clamping plate 10 are both slidably connected to the outside of the guide rod 6.
[0027] Specifically, the connecting post 13, which is connected to multiple illuminated character bodies 14, is inserted into the inside of the box cover 2. Then, the first motor 4 is started, and its output end drives the double-headed bidirectional lead screw 5 to rotate. Under the guidance of the guide rod 6, the first clamping plate 9 and the second clamping plate 10 in the first clamping assembly 7 and the second clamping assembly 8 will move smoothly towards each other. During this process, the first anti-slip pad 11 and the second anti-slip pad 12 play a buffering role, which can conveniently fix the connecting post 13 initially.
[0028] In this embodiment, a first upright plate 17 and a second upright plate 18 are fixedly connected to the upper end of the box cover 2. A rotating rod 16 is rotatably connected to the outer side of the first upright plate 17 and the second upright plate 18. The output end of a second motor 15 is fixedly connected to the front end of the rotating rod 16. The second motor 15 is fixedly installed on the upper end of the box cover 2. The limiting assembly includes a main gear. The inner side of the main gear is fixedly connected to the outer side of the rotating rod 16. A chain belt 19 meshes with the outer side of the main gear. A plurality of driven gears 20 corresponding to the connecting post 13 mesh with the inner side of the chain belt 19. The plurality of driven gears 20 are rotatably connected to the corresponding first upright plate 17 and the second upright plate 18. A limiting screw 21 is threadedly connected to the inner side of the driven gear 20. A limiting hole corresponding to the limiting screw 21 is opened on the outer side of the connecting post 13. The limiting screw 21 is located on the inner side of the connecting post 13.
[0029] Specifically, when the second motor 15 is started, its output end drives the rotating rod 16 to rotate. The two main gears fixed on the rotating rod 16 rotate accordingly, which in turn drives the chain belt 19 that meshes with it to rotate. The rotation of the chain belt 19 will drive multiple driven gears 20 to rotate synchronously. Since the inner side of the driven gear 20 is threaded with a limiting screw 21, when the driven gear 20 rotates, the limiting screw 21 will move closer to the connecting post 13. Finally, the limiting screw 21 can smoothly slide into the limiting hole opened on the outer side of the connecting post 13, thereby further limiting and fixing the connecting post 13 and effectively preventing it from moving.
[0030] In this embodiment, a sliding groove 22 is provided on the outer side of the limiting screw 21, and a slider adapted to the sliding groove 22 is fixedly connected on the first upright plate 17 and the second upright plate 18.
[0031] Specifically, the sliding groove 22 on the outside of the limiting screw 21 slides with the sliders on the first vertical plate 17 and the second vertical plate 18, which further improves the stability of the sliding process.
[0032] In this embodiment, the lower end of the first motor 4 is fixedly connected to a mounting plate 3, and the mounting plate 3 is fixedly installed at the front end of the housing 1.
[0033] Specifically, the design of mounting plate 3 can effectively improve the stability of the first motor 4 during operation.
[0034] It should be noted that this utility model is an assembly frame for LED illuminated letters. When the user needs to assemble multiple illuminated letter bodies 14 on the box 1, firstly, the connecting post 13 connected to the multiple illuminated letter bodies 14 is inserted into the inside of the box cover 2. Then, the first motor 4 is started, and its output end drives the double-headed bidirectional lead screw 5 to rotate. Under the guidance of the guide rod 6, the first clamping plate 9 and the second clamping plate 10 in the first clamping assembly 7 and the second clamping assembly 8 will move smoothly towards each other. During this process, the first anti-slip pad 11 and the second anti-slip pad 12 play a buffering role, which can conveniently fix the connecting post 13 initially.
[0035] After initial fixing, the second motor 15 is started, and its output end drives the rotating rod 16 to rotate. The two main gears fixed on the rotating rod 16 rotate accordingly, which in turn drives the chain belt 19 that meshes with it to rotate. The rotation of the chain belt 19 will drive multiple driven gears 20 to rotate synchronously. Since the inner side of the driven gear 20 is threadedly connected to the limiting screw 21, when the driven gear 20 rotates, the limiting screw 21 will move closer to the connecting column 13. At the same time, the sliding groove 22 on the outer side of the limiting screw 21 slides and engages with the sliders on the first vertical plate 17 and the second vertical plate 18, which further improves the stability of the sliding process. Finally, the limiting screw 21 can smoothly slide into the limiting hole opened on the outer side of the connecting column 13, thereby further limiting and fixing the connecting column 13 and effectively preventing its movement.
