Description

Technical Field

[0001] This utility model relates to the field of billboard technology, and in particular to a convenient card-mounted double-layer luminous billboard. Background Technology

[0002] Double-layer illuminated billboards are an innovative dynamic visual communication device consisting of two independently controllable light-emitting panels. Their core structure typically uses high-brightness LED light strips, light guide plates, or flexible electroluminescent films as the light-emitting layer, combined with a high-transmittance acrylic or glass shell to create a three-dimensional luminous effect.

[0003] Traditional double-layer illuminated billboards are generally assembled using bolt fastening structures, requiring tools such as screwdrivers and electric drills to connect and fix the lettering panels to the back panel. In scenarios such as outdoor advertising installation, commercial window renovation, or temporary event display board construction, this assembly method has significant drawbacks: installers need to frequently climb to heights, and operating tools in narrow or high-altitude environments is extremely inconvenient. Furthermore, the bolt holes need to be precisely aligned, and even slight deviations require rework and adjustment, resulting in a single installation taking 15-30 minutes, which seriously restricts on-site construction efficiency. Especially in scenarios where advertising content needs to be frequently changed, such as shopping mall promotional display boards and temporary exhibition booths, repeated disassembly and assembly of bolts will also accelerate the wear of the holes, causing the structure to loosen.

[0004] Therefore, when used in narrow or high-altitude work environments, there is a problem with the inconvenience of quickly assembling the lettering and backing panels. To address this, a convenient snap-fit ​​double-layer illuminated billboard can be designed. When using this type of billboard, the backing panel is first fixed to a pre-reserved groove in the wall using bolts. Then, multiple sets of insert rods on the inner wall of the lettering panel are aligned with the insert holes on the outer wall of the backing panel and inserted. The inclined surface of the insert rod end first enters the insert cylinder. At this time, the locking mechanism moves upward along the inclined surface and compresses the internal spring. When the insert rod is fully inserted into the insert cylinder, the restoring force of the spring pushes the locking mechanism downward to embed into the top slot of the insert rod, forming a vertical constraint force to complete the quick assembly of the lettering and backing panels. In summary, this technical solution uses the axial positioning of the insert rods and insert cylinder combined with the elastic constraint of the locking mechanism to enable tool-free quick assembly of the lettering and backing panels, improving installation efficiency. Utility Model Content

[0005] Traditional double-layer illuminated billboards are generally assembled using bolt fastening structures. Installers need to frequently climb to heights to work, and it is extremely inconvenient to operate tools in narrow or high-altitude environments. In addition, the bolt holes need to be precisely aligned, and even a slight deviation requires rework and adjustment. Therefore, when used in narrow or high-altitude work scenarios, it is inconvenient to quickly assemble the letter panel and the back panel.

[0006] The technical solution of this utility model is as follows: a double-layer luminous advertising sign that is easy to install, including a back plate, a detachable letter plate on the outer wall of the back plate, and a plug-in rod. Multiple sets of plug-in rods are fixedly installed on the inner wall of the letter plate. The outer wall of the back plate has plug-in holes that are compatible with the multiple sets of plug-in rods. The inner wall of the back plate cavity has plug-in cylinders that correspond one-to-one with the multiple sets of plug-in holes. The top outer wall of the plug-in cylinder is provided with a locking mechanism. The end of the plug-in rod is provided with an inclined surface. The top outer wall of the plug-in rod is provided with a groove that is compatible with the locking mechanism. Multiple sets of LED beads are provided on both the letter plate and the inner wall of the back plate cavity. The back plate is fixedly connected to the wall by a bolt structure.

[0007] Preferably, when using this convenient snap-fit ​​double-layer luminous billboard, the back panel is first fixed to the pre-reserved groove in the wall using bolts. Then, multiple sets of plug-in rods on the inner wall of the letter panel are aligned with the plug-in holes on the outer wall of the back panel and inserted. The inclined surface of the plug-in rod end first enters the plug-in cylinder. At this time, the locking mechanism moves upward along the inclined surface and compresses the internal spring. When the plug-in rod is fully inserted into the plug-in cylinder, the restoring force of the spring pushes the locking mechanism downward to embed into the top hole groove of the plug-in rod, forming a vertical constraint force, thus completing the quick assembly of the letter panel and the back panel. In summary, this technical solution uses the axial positioning of the plug-in rod and the plug-in cylinder combined with the elastic constraint of the locking mechanism to enable tool-free quick assembly of the letter panel and the back panel, improving installation efficiency.

[0008] Preferably, multiple sets of insertion holes, multiple sets of insertion rods, and multiple sets of insertion cylinders are arranged in a one-to-one correspondence, with the insertion holes, insertion rods, and insertion cylinders on the same horizontal axis.

[0009] Preferably, the locking mechanism includes a fixed cylinder, a locking rod, and a locking hole. The fixed cylinder is fixedly installed on the top of the plug-in cylinder, and the locking rod is slidably installed inside the fixed cylinder. The locking hole that matches the locking rod is opened on the outer wall of the top of the plug-in rod.

[0010] Preferably, the locking mechanism also includes a fixing ring and a rigid spring. A fixing ring is fixedly installed on the outer wall of the middle of the locking rod. A rigid spring is fixedly installed between the upper surface of the fixing ring and the top wall of the inner cavity of the insertion tube. The upper end of the rigid spring is fixedly connected to the top wall of the inner cavity of the insertion tube, and the lower end of the rigid spring is fixedly connected to the upper surface of the fixing ring.

[0011] Preferably, a fixing plate is fixedly installed on the outer wall of the upper end of the locking rod, and the fixing plate is located above the fixing cylinder.

[0012] Preferably, a sliding bead is embedded and rotatably disposed at the lower end of the locking rod, and the lower end of the locking rod is embedded and slidably disposed inside the locking hole, and a sliding groove is provided between the upper end of the locking hole and the inclined surface.

[0013] The beneficial effects of this utility model are: 1. When using this convenient snap-fit ​​double-layer luminous billboard, the back panel is first fixed to the pre-reserved groove in the wall using bolts. Then, multiple sets of plug-in rods on the inner wall of the letter panel are aligned with the plug-in holes on the outer wall of the back panel and inserted. The inclined surface of the plug-in rod end first enters the plug-in cylinder. At this time, the locking mechanism moves upward along the inclined surface and compresses the internal spring. When the plug-in rod is fully inserted into the plug-in cylinder, the restoring force of the spring pushes the locking mechanism downward to embed into the top hole groove of the plug-in rod, forming a vertical constraint force to complete the quick assembly of the letter panel and the back panel. In summary, this technical solution uses the axial positioning of the plug-in rod and the plug-in cylinder combined with the elastic constraint of the locking mechanism to enable tool-free quick assembly of the letter panel and the back panel, improving installation efficiency.

[0014] 2. The triple axial alignment design of the insertion hole, insertion rod, and insertion sleeve ensures assembly accuracy.

[0015] 3. The dual-layer LED layout enables RGB three-primary-color mixed light emission, which can produce dynamic light effects such as gradient and flashing through program control, enhancing the visual appeal of advertisements.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example 1 Please see Figure 2 and Figure 5 This utility model provides an embodiment: a conveniently mounted double-layer luminous billboard, including a back plate 1, a detachable letter plate 2 on the outer wall of the back plate 1, and a plug-in rod 3. Multiple sets of plug-in rods 3 are fixedly arranged on the inner wall of the letter plate 2. The outer wall of the back plate 1 has plug-in holes that are compatible with the multiple sets of plug-in rods 3. The inner wall of the back plate 1 has a plug-in cylinder 13 that corresponds to each of the multiple sets of plug-in holes. The top outer wall of the plug-in cylinder 13 is provided with a locking mechanism. The end of the plug-in rod 3 is provided with an inclined surface. The top outer wall of the plug-in rod 3 is provided with a groove that is compatible with the locking mechanism. Multiple sets of LED beads 4 are provided on both the letter plate 2 and the inner wall of the back plate 1. The back plate 1 is fixedly connected to the wall by a bolt structure.

[0020] Please see Figure 1 and Figure 3 Multiple sets of insertion holes, multiple sets of insertion rods 3 and multiple sets of insertion cylinders 13 are set one-to-one. The insertion holes, insertion rods 3 and insertion cylinders 13 are on the same horizontal axis. The triple axial alignment design of the insertion holes, insertion rods 3 and insertion cylinders 13 ensures assembly accuracy.

[0021] Please see Figure 2 and Figure 4 The locking mechanism includes a fixed cylinder 5, a locking rod 6, and a locking hole 7. The fixed cylinder 5 is fixedly installed on the top of the plug-in cylinder 13. The locking rod 6 is slidably installed inside the fixed cylinder 5. The outer wall of the top of the plug-in rod 3 has a locking hole 7 that is compatible with the locking rod 6. When the locking rod 6 descends and embeds into the locking hole 7, it forms a vertical constraint force, completing the quick assembly of the letter plate 2 and the back plate 1. The locking mechanism also includes a fixed ring 8 and a rigid spring 9. The fixed ring 8 is fixedly installed on the middle outer wall of the locking rod 6. The rigid spring 9 is fixedly installed between the upper surface of the fixed ring 8 and the top wall of the inner cavity of the plug-in cylinder 13. The upper end of the rigid spring 9 is fixedly connected to the top wall of the inner cavity of the plug-in cylinder 13, and the lower end of the rigid spring 9 is fixedly connected to the upper surface of the fixed ring 8. The restoring force of the rigid spring 9 pushes the locking rod 6 to descend and embed into the locking hole 7.

[0022] Please see Figure 3 and Figure 4 A fixing plate 10 is fixedly installed on the outer wall of the upper end of the locking rod 6. The fixing plate 10 is located above the fixing cylinder 5. Pulling the locking rod 6 upward can disengage it from the interior of the locking hole 7. A sliding bead 11 is embedded and rotatably installed at the lower end of the locking rod 6. The lower end of the locking rod 6 is embedded and slidably installed inside the locking hole 7. A sliding groove 12 is opened between the upper end of the locking hole 7 and the inclined surface. The inclined surface of the end of the plug rod 3 first enters the interior of the plug cylinder 13. At this time, the sliding bead 11 at the lower end of the locking rod 6 of the locking mechanism slides along the sliding groove 12 on the top surface of the plug rod 3. At the same time, the locking rod 6 moves upward along the inclined surface and compresses the rigid spring 9 through the fixing ring 8.

[0023] When using this convenient card-mounted double-layer luminous billboard, the working principle of the convenient card-mounted double-layer luminous billboard is as follows: During installation, the back plate 1 is first fixed in the reserved groove in the wall by bolt structure, and then the multiple sets of plug-in rods 3 on the inner wall of the letter plate 2 are aligned with the plug-in holes on the outer wall of the back plate 1 and inserted.

[0024] The inclined surface at the end of the plug rod 3 first enters the interior of the plug tube 13. At this time, the sliding ball 11 at the lower end of the locking rod 6 of the locking mechanism slides along the sliding groove 12 on the top surface of the plug rod 3. At the same time, the locking rod 6 moves upward along the inclined surface and compresses the rigid spring 9 through the fixed ring 8.

[0025] When the plug rod 3 is fully inserted into the plug tube 13, the locking rod 6 and the locking hole 7 are on the same vertical axis. The restoring force of the rigid spring 9 pushes the locking rod 6 down to embed into the locking hole 7, forming a vertical constraint force to complete the quick assembly of the letter plate 2 and the back plate 1.

[0026] Multiple sets of LED beads 4 on the inner wall of the back panel 1 and the inner cavity of the letter panel 2 emit light synchronously, and the double-layer structure produces a color-changing effect through the superposition of the LED beads 4.

[0027] In summary, firstly, the technical solution employs the axial positioning of the plug-in rod 3 and the plug-in cylinder 13, combined with the elastic constraint of the locking mechanism, to enable tool-free rapid assembly of the letter plate 2 and the back plate 1, thereby improving installation efficiency. Secondly, the triple axial alignment design of the plug-in hole, plug-in rod 3, and plug-in cylinder 13 ensures assembly accuracy. Thirdly, the double-layer LED bead 4 layout enables RGB three-primary-color mixed light emission, which can produce dynamic light effects such as gradient and flashing through program control, enhancing the visual appeal of the advertisement.

[0028] In summary, the overall solution, through the combination of structural innovation and optical design, not only solves the problem of cumbersome installation of traditional billboards, but also expands the visual expressiveness of advertising displays through double-layer light-emitting technology.

[0029] Through the above steps, when using this convenient card-mounted double-layer luminous billboard, the back plate 1 is first fixed to the pre-reserved groove in the wall using bolts. Then, the multiple sets of plug-in rods 3 on the inner wall of the letter plate 2 are aligned with the plug-in holes on the outer wall of the back plate 1 and inserted. The inclined surface of the end of the plug-in rod 3 first enters the interior of the plug-in cylinder 13. At this time, the locking mechanism moves upward along the inclined surface and compresses the internal spring. When the plug-in rod 3 is fully inserted into the plug-in cylinder 13, the restoring force of the spring pushes the locking mechanism downward to embed into the top hole groove of the plug-in rod 3, forming a vertical constraint force to complete the quick assembly of the letter plate 2 and the back plate 1. In summary, this technical solution uses the axial positioning of the plug-in rod 3 and the plug-in cylinder 13 combined with the elastic constraint of the locking mechanism to enable the letter plate 2 and the back plate 1 to achieve tool-free quick assembly and improve installation efficiency.

[0030] Example 2 Back panel 1 and letter panel 2 adopt a modular design. Back panel 1 and letter panel 2 are not limited to any shape or size. Multiple sets of plug holes on the outer wall of back panel 1 can be adapted to letter panels 2 of various shapes and sizes such as fan-shaped, rectangular, and irregular shapes, to meet personalized customization needs.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
