Abstract
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 consistent with 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 an opaque plate, a translucent plate and a reflective film, wherein a non-hollowed-out depression zone is provided inwardly on the front surface of the opaque plate according to the requirement of luminous indication, a hollowed-out zone corresponding to the luminous indication graphic is provided on the opaque plate within the range of the depression zone to form a step fixing portion around the hollowed-out zone, and the size and shape of the translucent plate correspond to the depression zone to be supported and fixed on the step fixing portion to cover the hollowed-out zone, and to be in the same plane as the opaque plate to facilitate the pasting of the reflective film.
[0008] As a further improvement of the above technical solution:
[0009] The light-transmitting plate is fixed on the step fixing part by adhesive, and a plurality of shallow grooves are provided on the bearing surface of the step fixing part for accommodating the adhesive and increasing the adhesive force.
[0010] The light-transmitting plate is fixed on the step fixing portion by countersunk screws.
[0011] The edge of the opaque plate at the settling 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 settling area.
[0012] The light-proof plate is made of an aluminum alloy plate, or an extruded aluminum alloy profile, or a thin steel plate, or a synthetic resin plate.
[0013] The light-transmitting plate is made of PC light-transmitting plate.
[0014] The light source assembly includes an LED light source board.
[0015] Compared with the prior art, the advantages of the utility model are:
[0016] First, the luminous road traffic sign of the utility model is provided with a special structure of opaque plate and translucent plate, and a unique hollow area, a sinking area and a step fixing part are opened on the opaque plate. This special structural connection and matching method completely subverts the backward technology of using long-pointed screws in the prior art, so that there is no need to use long-pointed screws to tighten and fix them one by one, and there is no need to cut and grind the long-pointed screws extending out of the panel. This 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.
[0017] Second, the luminous road traffic sign of the utility model uses a special settling area to embed the light-transmitting plate in the opaque plate, and whether the light-transmitting plate is fixed by gluing or countersunk screws, these two fixing methods will not leave bulges on the light-transmitting plate that affect the reflective film, 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.
[0018] Third, the luminous road traffic sign of the utility model has a guiding slope on the edge of the opaque plate at the settlement area, and a corresponding guiding slope on the edge of the transparent plate is used to guide the transparent plate into the settlement area. This allows the transparent plate to be quickly and accurately embedded in the settlement 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.
[0031] like Figures 1 to 6As 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 an opaque plate 11, a translucent plate 12 and a reflective film 13. The front surface of the opaque plate 11 (the front surface is the side of the opaque plate 11 for pasting the reflective film, and the corresponding other side is the rear surface, and the rear surface faces the light source assembly 4) is provided with a non-hollowed-out settling area 112 facing inward according to the luminous indication requirements. The opaque plate 11 is provided with a hollowed-out area 111 corresponding to the luminous indication graphic within the range of the settling area 112 to form a step fixing portion 113 around the hollowed-out area 111. The size and shape of the translucent plate 12 corresponds to the settling area 112 and is used to bear and fix on the step fixing portion 113 to cover the hollowed-out area 111, and is used to be in the same plane with the opaque plate 11 to facilitate pasting of the reflective film. The specific implementation principle is as follows:
[0032] 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 1 As shown in A in FIG. In this embodiment, the "Nanda Main Line" 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 opaque plate 11 in this embodiment is an aluminum plate, and the transparent plate 12 is a PC transparent plate.
[0033] During production, first, according to the luminous indication requirements (in this embodiment, "Nanda"), a non-hollowed-out depression area 112 is opened inward on the front surface of the opaque plate 11 using existing processing equipment (such as a milling machine), that is, the depression area 112 is only milled to a certain thickness on the front surface of the opaque plate 11, and the entire opaque plate 11 is not hollowed out. At the same time, since the present technology has been limited to opening a hollow area 111 consistent with the luminous indication graphic within the scope of the depression area 112, and a step fixing portion 113 is formed around the hollow area 111, it is inevitable that the area of the depression area 112 must be larger than the area of the hollow area 111, which can also be intuitively understood from the drawings in the specification.
[0034] After the settling area 112 is opened, a light-transmitting plate 12 of the same size and shape as the settling area 112 is manufactured. Then, a hollow area 111 consistent with the luminous indication graphic (in this embodiment, "Nanda") is opened within the settling area 112 using existing processing equipment (such as a milling machine or laser cutting technology), that is, the two characters "Nanda" are hollowed out. Since the settling area 112 is non-hollowed out, and the hollow area 111 is hollowed out, the non-hollowed settling area 112 and the adjacent hollow area 111 are bound to form a step fixing portion 113.
[0035] Then the light-transmitting plate 12 is embedded in the sinking area 112 and fixed on the step fixing part 113 (for example, by gluing or countersunk screws, which is convenient and quick), so that the light-transmitting plate 12 can just cover the hollow area 111 of "Nanda". At the same time, since the thickness of the light-transmitting plate 12 is consistent with the sinking depth of the sinking area 112, the light-transmitting plate 12 and the opaque plate 11 are in the same plane, which is convenient for pasting the reflective film 13. At the same time, the light-transmitting plate 12 covers the luminous hollow area 111 of "Nanda", so that when the light source assembly 4 emits light at night, the light can pass through the hollow area 111, the light-transmitting plate 12, and the reflective film 13 to light up "Nanda".
[0036] Of course, in other embodiments, the following operation can also be performed: during production, first mark and locate the range of the settling area 112 on the front surface of the opaque plate 11 according to the luminous indication requirements (that is, "Nanda" in this embodiment), and then mark and locate the range of the hollow area 111 of "Nanda" within the range of the settling area 112, that is, the range of the settling area 112 is larger than the range of the hollow area 111. At the same time, a translucent plate 12 with the same size and shape as the settling area 112 is produced. Then, the hollow area 111 of "Nanda" is milled inwardly using existing processing equipment (such as a milling machine) to form a hollow. Then, the nearby settling area 112 is milled to a certain thickness, but not milled through, so as to form a non-hollowed settling area 112. This is just a difference in construction technology, but it is still based on the special structural settings and special connection and matching methods of the opaque plate 11, the translucent plate 12, the hollow area 111, the settling area 112, and the step fixing portion 113.
[0037] Through the above special scientific design, it has the following technical advantages:
[0038] First, the luminous road traffic sign of the utility model is provided with a light-proof plate 11 and a light-proof plate 12 of a special structure, and a unique hollow area 111, a sinking area 112 and a step fixing part 113 are provided on the light-proof plate 11. This special structural connection and matching method completely subverts the backward technology of using long-pointed screws in the prior art, so that the inefficient operation of tightening and fixing long-pointed screws is no longer required, and the long-pointed screws extending out of the panel are no longer required to be cut and polished, 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.
[0039] Second, the luminous road traffic sign of the utility model uses a special settling area 112 to embed the light-transmitting plate 12 in the opaque plate 11, and whether the light-transmitting plate 12 is fixed by gluing or countersunk screws, these two fixing methods will not leave a protrusion on the light-transmitting plate 12 that affects the reflective film 13, which makes the reflective film 13 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 13 is beautifully pasted, and the aesthetics of the luminous road traffic sign and the safety of traffic instructions are greatly improved.
[0040] In this embodiment, the light-transmitting plate 12 is fixed to the step fixing portion 113 by adhesive, and a plurality of shallow grooves 1131 are provided on the bearing surface of the step fixing portion 113 to accommodate the adhesive and increase the adhesive force. When the settling area 112 is provided, a plurality of shallow grooves 1131 are further provided on the bearing surface of the step fixing portion 113 by using existing processing equipment (such as a milling machine), which forms a rough process surface, which is convenient for accommodating the adhesive and increasing the adhesive force, so that the light-transmitting plate 12 is adhered more firmly.
[0041] In this embodiment, the light-transmitting plate 12 is fixed to the step fixing portion 113 by means of a countersunk screw 14. The countersunk screw 14 can be sunk into the light-transmitting plate 12, so that no protrusions that affect the reflective film 13 are left on the light-transmitting plate 12, which makes the reflective film 13 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 13 is beautifully pasted, and the aesthetics of the luminous road traffic sign and the safety of traffic instructions are greatly improved.
[0042] In this embodiment, the edge of the opaque plate 11 at the settling area 112 is provided with a guide slope (such as Figure 3 The guide slope is milled out by a machine during production), and the edge of the light-transmitting plate 12 is also provided with a corresponding guide slope (such as Figure 3 At B shown in the figure, a guide slope is milled by a machine during manufacturing to guide the light-transmitting plate 12 into the settling area 112. This allows the light-transmitting plate 12 to be quickly and accurately embedded in the settling area 112 when it is placed, and the fixing effect is better after the limit.
[0043] In this embodiment, the opaque plate 11 is made of an aluminum alloy plate, or an extruded aluminum alloy profile, or a thin steel plate, or a synthetic resin plate (the synthetic resin plate is an opaque synthetic resin plate).
[0044] In this embodiment, the light-transmitting plate 12 is made of a PC light-transmitting plate.
[0045] In this embodiment, the light source assembly 4 includes an LED light source board.
[0046] 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.
