Description

Technical Field

[0001] The utility model mainly relates to the field of road traffic sign manufacturing, in particular to a luminous road traffic sign. Background Art

[0002] With the development of road traffic, the beautification of roads, and the improvement of traffic safety requirements, more and more road traffic luminous signs are used. In the existing luminous signs, a hollow area corresponding to the luminous indication image is opened on the opaque panel, and a first light-transmitting plate is arranged in the hollow area, so that the indication image can emit light when it is lit. However, in order to fix the first light-transmitting plate in the hollow area, it is necessary to first set a second light-transmitting plate on the back of the panel, so that the first light-transmitting plate can be fixed on the second light-transmitting plate, so that the light source can be lit through the second light-transmitting plate and the first light-transmitting plate in turn. This structure seems simple, but there will be great problems and troubles in the actual manufacturing.

[0003] First of all, the area of ​​the opaque panel is very large, especially for large-area signboards, where the panel area reaches dozens of square meters. For this reason, when making it, it is necessary to first manufacture the panel, open a hollow area on the panel, and then lay the panel upside down with the back of the panel facing up, place the second light-transmitting plate on the back of the panel at the hollow area, and use long-pointed screws to fix the second light-transmitting plate on the panel from back to front. Due to the large area of ​​the panel and the relative fragility of the second light-transmitting plate, it is impossible to lift it to a sprint rivet machine with high pressure for riveting and fixing, so it can only be fixed with long-pointed screws. Moreover, due to the large area of ​​the panel, if the fixing method from front to back is adopted, the operator often cannot see the second light-transmitting plate on the rear side, so the only way is to twist the screws from back to front; and in the back-to-front method, the second light-transmitting plate is carried on the back of the panel, so it can be tightened and fixed more effectively.

[0004] However, this structure and operation method will lead to a technical problem: because the panel and the second light-transmitting plate are not thick enough, in order to increase the thread contact surface, the long-pointed screw must be penetrated from the back to the front of the panel, and the long-pointed screw should be expanded as much as possible to expand the panel and the second light-transmitting plate to increase the effective thread contact. This will cause a section of the screw to protrude from the front of the panel. After the fixing is completed, the panel needs to be turned over, and then a cutting machine, grinder and other equipment are used to grind the protruding screws on the panel flat before the reflective film can be pasted. This structure and operation method greatly increases the labor intensity of production, makes the manufacturing process very complicated, and greatly reduces the efficiency of product production. Moreover, due to uneven grinding, the reflective film is often unqualified or punctured in the later stage, which makes rework time-consuming and labor-intensive, and the discarded reflective film also greatly increases the production cost. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a luminous road traffic sign which is simple and beautiful in structure, easy to manufacture, greatly reduces the manufacturing intensity and manufacturing cost, greatly improves the manufacturing efficiency, has a good luminous effect, and is particularly suitable for large-area production.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A luminous road traffic sign comprises a panel assembly, a back panel assembly, a frame rod assembly and a light source assembly, wherein the panel assembly comprises a surface opaque plate, a bottom opaque plate, a translucent plate and a reflective film, wherein the surface opaque plate is provided with a large hollow area, the bottom opaque plate is fixed on the back of the surface opaque plate to cover the large hollow area, the bottom opaque plate is provided with a small hollow area corresponding to the luminous indication graphic within the large hollow area, the size and shape of the translucent plate correspond to the large hollow area, the translucent plate is embedded in the large hollow area and is supported and fixed on the bottom opaque plate to be in the same plane as the surface opaque plate to facilitate the pasting of the reflective film.

[0008] As a further improvement of the above technical solution:

[0009] The surface opaque plate is formed by laying and splicing a plurality of opaque plates, and a plurality of large hollow areas are opened on the surface opaque plate. Each of the large hollow areas is provided with an independent bottom opaque plate for covering the large hollow area, and each of the large hollow areas is embedded with an independent light-transmitting plate.

[0010] The surface opaque plate and the bottom opaque plate are both formed by laying a plurality of opaque plates flat and splicing each other. The surface opaque plate is provided with a plurality of large hollow areas. The bottom opaque plate is integrally fixed to the back of the surface opaque plate to cover the plurality of large hollow areas at the same time. An independent light-transmitting plate is correspondingly embedded in each of the large hollow areas.

[0011] The edge of the surface opaque plate at the large hollow area is provided with a guiding slope, and the edge of the light-transmitting plate is also provided with a corresponding guiding slope for guiding the light-transmitting plate into the large hollow area.

[0012] The bottom layer opaque plate is fixed to the back side of the surface layer opaque plate by rivets, and the transparent plate is fixed to the front side of the surface layer opaque plate by countersunk self-tapping screws or adhesive.

[0013] The surface opaque plate and the bottom opaque plate are made of aluminum alloy plates, or extruded aluminum alloy profiles, or thin steel plates, or synthetic resin plates.

[0014] The light-transmitting plate is made of PC light-transmitting plate.

[0015] The light source assembly includes an LED light source board.

[0016] Compared with the prior art, the advantages of the utility model are:

[0017] First, the luminous road traffic sign of the utility model completely overturns the backward technology of using long-pointed screws in the prior art by setting a special structure of the surface opaque plate, the bottom opaque plate, and the translucent plate, and adopting a special structural connection and matching method, so that there is no need to use long-pointed screws to tighten and fix the inefficient operation, and there is no need to cut and grind the long-pointed screws extending out of the panel, which greatly reduces the labor intensity of production, makes the manufacturing process very simple, and greatly improves the product production efficiency. It seems to be just a structural adjustment, but it brings about a simple innovation of many complicated technical processes behind the production and manufacturing, and the technical effect and economic benefits achieved are excellent.

[0018] Second, the luminous road traffic sign of the utility model can be welded or riveted on the surface opaque plate and the bottom opaque plate. Both fixing methods will not leave bulges on the panel that affect the reflective film. The transparent plate is fixed with adhesive, which makes the reflective film easy and quick to paste, greatly reduces the possibility of pasting errors, and greatly reduces the occurrence of waste reflective film. In addition, due to the high flatness, the reflective film is beautifully pasted, and the aesthetics of the luminous road traffic sign and the safety of traffic instructions are greatly improved.

[0019] Third, the luminous road traffic sign of the utility model has a guiding slope on the edge of the surface opaque plate at the large hollow area, and a corresponding guiding slope is also provided on the edge of the light-transmitting plate to guide the light-transmitting plate into the large hollow area. This allows the light-transmitting plate to be quickly and accurately embedded in the large hollow area when placed, and the fixing effect is better after limiting. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] like Figures 1 to 4As shown, the luminous road traffic sign of this embodiment includes a panel assembly 1, a back panel assembly 2, a frame rod assembly 3 and a light source assembly 4. The panel assembly 1 includes a surface opaque plate 11, a bottom opaque plate 12, a light-transmitting plate 13 and a reflective film 14. A large hollow area 111 is provided on the surface opaque plate 11. The bottom opaque plate 12 is fixed on the back of the surface opaque plate 11 to cover the large hollow area 111. A small hollow area 121 corresponding to the luminous indication graphic is provided on the bottom opaque plate 12 within the large hollow area 111. The size and shape of the light-transmitting plate 13 correspond to the large hollow area 111. The light-transmitting plate 13 is embedded in the large hollow area 111 and is supported and fixed on the bottom opaque plate 12 to be in the same plane as the surface opaque plate 11 to facilitate the pasting of the reflective film 14. The specific implementation principle is as follows:

[0031] like Figure 1 As shown, the luminous indication graphic of the luminous sign in this embodiment is "Nanda Main Line", as shown in FIG. Figure 4 As shown in A in FIG. The "Nanda Main Line" of this embodiment is divided into two independent areas, "Nanda" and "Main Line", which are not connected together. Of course, in other embodiments, it can be regarded as one area. Therefore, the following only takes the independent area "Nanda" as an example. At the same time, the surface opaque plate 11 and the bottom opaque plate 12 in this embodiment are both aluminum plates.

[0032] During the production, a large hollow area 111 is firstly opened on the surface opaque plate 11 corresponding to the area of ​​"Nanda" that needs to be illuminated (for example, by using laser cutting technology, which is convenient and quick), and the area of ​​the large hollow area 111 is obviously larger than the two characters "Nanda". In addition, a bottom opaque plate 12 corresponding to the large hollow area 111 is manufactured, and the area of ​​the bottom opaque plate 12 is larger than the area of ​​the large hollow area 111, so that the bottom opaque plate 12 can be fixed to the back of the surface opaque plate 11 (for example, directly welded or riveted, which is convenient and quick, and has an excellent fixing effect), so that the bottom opaque plate 12 covers and hides the large hollow area 111. A small hollow area 121 corresponding to the luminous indication graphic is opened on the bottom opaque plate 12 and within the scope of the large hollow area 111 (for example, using laser cutting technology, which is convenient and quick), that is, a small luminous hollow area 121 of "Nanjing University" is opened, and this small hollow area 121 is within the scope of the large hollow area 111.

[0033] At the same time, a light-transmitting plate 13 with the same size and shape as the large hollow area 111 has been prepared. After the bottom opaque plate 12 is fixed, the light-transmitting plate 13 is embedded in the large hollow area 111 from the front side of the surface opaque plate 11, and is carried and fixed on the bottom opaque plate 12 (by gluing, which is convenient and quick). At this time, the light-transmitting plate 13 and the surface opaque plate 11 are in the same plane, which is convenient for pasting the reflective film 14. At the same time, below the light-transmitting plate 13 is the luminous small hollow area 121 of "Nanjing University" on the bottom opaque plate 12, so that when the light source assembly 4 is illuminated at night, the light can pass through the small hollow area 121, the light-transmitting plate 13, and the reflective film 14 to light up "Nanjing University".

[0034] Through the above special scientific design, it has the following technical advantages:

[0035] First, the luminous road traffic sign of the utility model completely overturns the backward technology of using long-pointed screws in the prior art by setting a special structure of the surface opaque plate 11, the bottom opaque plate 12, and the translucent plate 13, and adopting a special structural connection and matching method, so that there is no need to use long-pointed screws to tighten and fix the inefficient operation, and there is no need to cut and grind the long-pointed screws extending out of the panel, which greatly reduces the labor intensity of production, makes the manufacturing process very simple, and greatly improves the product production efficiency. It seems to be just a structural adjustment, but it brings about a simple innovation of many complicated technical processes behind the production and manufacturing, and the technical effect and economic benefits achieved are excellent.

[0036] Second, the luminous road traffic sign of the utility model can be welded on the surface opaque plate 11 and the bottom opaque plate 12, or can be riveted by sprinting. Both fixing methods will not leave bulges on the panel that affect the reflective film 14. The transparent plate 13 is fixed with adhesive, which makes the reflective film 14 easy and quick to paste, greatly reduces the possibility of pasting errors, and greatly reduces the occurrence of waste reflective film. In addition, due to the high flatness, the reflective film is beautifully pasted, and the aesthetics of the luminous road traffic sign and the safety of traffic instructions are greatly improved.

[0037] In this embodiment, the edge of the surface opaque plate 11 at the large hollow area 111 is provided with a guide slope (such as Figure 2 The guide slope is milled out by machine during production), and the edge of the light-transmitting plate 13 is also provided with a corresponding guide slope (such as Figure 2 At B shown in the figure, a guide slope is milled by a machine during production to guide the light-transmitting plate 13 into the large hollow area 111. This allows the light-transmitting plate 13 to be quickly and accurately embedded in the large hollow area 111 when it is placed, and the fixing effect is better after limiting.

[0038] In this embodiment, the bottom opaque plate 12 is fixed to the back of the surface opaque plate 11 by rivets, and the light-transmitting plate 13 is fixed to the front of the surface opaque plate 11 by countersunk self-tapping screws or adhesive. The rivets can be sprint riveted, which has a good fixing effect and does not leave a protrusion that affects the flatness. The countersunk self-tapping screws can be embedded in the fixing holes of the light-transmitting plate 13, which has a good fixing effect and does not leave a protrusion that affects the flatness.

[0039] In this embodiment, the surface opaque plate 11 and the bottom opaque plate 12 are made of aluminum alloy plates, or extruded aluminum alloy profiles, or thin steel plates, or synthetic resin plates. Of course, in other embodiments, they can also be made of other opaque materials.

[0040] In this embodiment, the light-transmitting plate 13 is made of a PC light-transmitting plate. Of course, in other embodiments, it can also be made of other light-transmitting materials.

[0041] In this embodiment, the light source assembly 4 includes an LED light source board.

[0042] Inspired by the above technical features, two specific application embodiments are provided below:

[0043] Specific application example 1: This example is a large-area signboard, so the surface opaque plate 11 is formed by paving and splicing multiple opaque plates (for example, welding). Since there are multiple luminous indicating graphics on the surface opaque plate 11, multiple large hollow areas 111 are provided. Each large hollow area 111 is provided with an independent bottom opaque plate 12 to cover the large hollow area 111, and each large hollow area 111 is embedded with an independent light-transmitting plate 13. That is, there are no multiple bottom opaque plates 12 and light-transmitting plates 13, and they are provided corresponding to each large hollow area 111. This reduces the overall area of ​​the bottom opaque plate 12, saves costs, and reduces the overall weight of the signboard.

[0044] Specific application example 2: This example is a signboard of small or medium size. The surface opaque board 11 and the bottom opaque board 12 are both formed by paving and splicing multiple opaque boards. Since there are multiple luminous indicating graphics on the surface opaque board 11, multiple large hollow areas 111 are provided. Since the bottom opaque board 12 is a whole piece, it is directly fixed to the back of the surface opaque board 11 as a whole to cover the multiple large hollow areas 111 at the same time. Each large hollow area 111 is correspondingly embedded with an independent light-transmitting board 13. Since the bottom opaque board 12 is a whole piece, it is convenient and quick to fix.

[0045] Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the art can use the above disclosed technical content to make many possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention should fall within the scope of protection of the technical solution of the present invention.
