Description

Road traffic sign

Technical Field

The utility model relates to a road traffic sign makes the field, especially relates to a road traffic sign.

Background

With the development of road traffic, the beautification of roads and the improvement of traffic safety requirements, the application of road traffic luminous signs is more and more. In the prior art, four frame sectional materials (shown as a in fig. 1) are sequentially connected through four elbows (shown as B in fig. 1) to form a frame part of the sign, a transparent sign panel is installed on the front side of the frame, and a bottom plate is installed on the back side of the frame to form a box body in a matching manner. And the front of the sign panel is pasted with a reflective film with traffic indication pictures and texts, a light source plate is arranged between the sign panel and the bottom plate, the front of the sign panel can play a role in indicating in daytime, and meanwhile, the front can also play a role in indicating by light transmission when the back of the sign panel emits light at night.

In the prior art, part of luminous road traffic signs have the following defects:

in the conventional luminous traffic road sign, two adjacent frame profiles (shown as a in fig. 1) are connected by an elbow (shown as B in fig. 1). Referring to fig. 3, 4 and 5, three different conventional manufacturing methods are shown. During manufacturing, the outer sides of two adjacent frame profiles are fixedly connected through the elbow B, and then the inner sides of the two adjacent frame profiles are directly welded (at the welding position G shown in figures 1 and 3), so that the two frame profiles are firmly connected. This way of production is suitable for the production of signs with smaller dimensions (as shown in fig. 3), but if large-area signs (tens of squares) are to be produced, many owners or buyers are subjected to the requirement that the length of the arc-shaped edge at the bend of the large-area sign must be increased simultaneously to form the aesthetic visual effect of a "large bend", which makes the distance between two adjacent border profiles longer in order to form the aesthetic visual effect of a large bend. In this case, if the manufacturing method using one elbow connection is adhered to before, there are two different problems: firstly, as shown in fig. 4, the width of the two frame profiles is not changed, but the inner sides of the two frame profiles which are farther away cannot be contacted and welded, and the connection of the two frame profiles by only one elbow tends to make the connection of the two frame profiles unstable, especially for large-area traffic signs, the stability is more important. Secondly, as shown in fig. 5, if the inner sides of two adjacent frame profiles are welded as before, the width of the frame profiles must be increased, but the widened frame (obviously, the width of the frame in fig. 5 is much wider than that of the frames in fig. 3 and 4) not only affects the overall beauty of the signboard, but also greatly increases the manufacturing cost, greatly increases the self weight of the sign, and is not beneficial to transportation and suspension.

Secondly, as shown in fig. 1, a frame light bar (as shown in fig. 1 and 2C) is installed in a frame profile (as shown in fig. 1 a) of the partial luminous road traffic sign, so that a circle of edge lighting effect is formed when the road traffic sign is luminous. In order to make the bend emit light, the prior art adopts a long light bar as shown in fig. 1 and 2, wherein a straight strip part of the light bar is used for being inserted into the frame section bar, and an arc part is arranged at the end part of the light bar, and the arc part is used for making the bend emit light. However, the arc-shaped portion is cut into an arc shape during manufacturing, so that a part of original lamp beads on the lamp strip is cut off, for example, an F lamp bead shown in fig. 2, which is originally located on the long lamp strip, but when the arc-shaped portion needs to be cut off, the F lamp bead located along the edge line is inevitably cut off (for illustration, the F lamp bead is marked in the figure, and should not exist actually). This makes the brightness of the arc portion at the position not bright as compared with the brightness of the other positions, resulting in uneven light emission at the bend. For the luminous road traffic sign, the overall attractiveness of the sign is influenced due to uneven light emission at each elbow, the risk of visual illusion caused by uneven light emission exists, and the traffic safety is influenced to a certain extent.

Thirdly, as above-mentioned the second point, when the lamp pearl of this kind of structure only elbow department damaged, the staff need all take out whole root length lamp strip and carry out whole change, this has increased the work load of changing the maintenance operation, has increased the product cost of changing the maintenance secondly.
