Description

Combined frame section bar for road traffic sign

Technical Field

The utility model relates to a road traffic sign makes the field, especially relates to a frame section bar for road traffic sign that can make up.

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, a transparent sign panel is adopted for part of traffic luminous signs, a reflective film with traffic indication pictures and texts is pasted on the front surface of the sign panel, a light source plate is arranged on the back surface of the sign panel, the front surface can play a role in normal indication in daytime or reflective indication at night, and meanwhile, the front surface can also play a role in indication by light transmission when the back surface emits light at night.

In the prior art, part of the traffic luminous signs not only need to light the middle pictures and texts, but also need to light a circle of edge picture and text parts at the sign frame. Therefore, part of the prior art adopts a sign frame with a light trough, and a circle of edge image-text parts at the sign frame are lightened through a lamp panel in the light trough. But has the following disadvantages:

firstly, the structure of the existing frame is too much single, and the combination and the disassembly cannot be realized. Some conventional traffic signs may need to be changed to one that illuminates the border portion after a certain period of time. At the moment, the original common signs can only be completely abandoned, and a new set of traffic signs are manufactured by reusing the sign frame with the lamp groove, so that the resource waste is very serious, the time consumption for the re-manufacturing is long, the labor intensity is high, the working efficiency is low, and the rapid change can not be realized.

Secondly, current frame sets up first through-hole, second through-hole and mounting groove side by side in proper order, places the lamp strip in the mounting groove, and first through-hole, second through-hole are for sealing the through-hole. Two adjacent frames are connected by adopting a special matched elbow, two special flanges matched with the first through hole and the second through hole are arranged at two ends of the elbow, and the two flanges are inserted into the first through hole and the second through hole during connection. The first through hole and the second through hole are closed through holes, so that the flange cannot be seen after the insertion. This type of construction does not provide a good fastening effect, the inserted flange does not provide a good and secure connection to the frame, and since the flange is not visible, there is no way to find and improve where the two are not properly connected (e.g., where the surfaces do not contact each other for tightening, etc.). The connection is not stable, the structural problem of the traffic sign is easily caused, and loosening and even dropping are easy to occur during transportation or high-altitude hoisting, so that the safety of operation is seriously threatened. And because the instability of the structure, even if no problem is found during installation, the risk of falling off is very likely to occur along with the outdoor wind and rain of the traffic sign, and the safety of pedestrians and vehicles on the road surface is seriously influenced.

Thirdly, the existing frame is unreasonable in arrangement. When a sign needs to be hoisted, the prior art is to arrange a workpiece hoisting mode on an upper frame. Firstly, punching a plurality of holes on the frame before welding adjacent frames, then putting a plurality of screw members into the closed first through hole and the closed second through hole through the end part of the frame, so that the screw members extend out of the holes from bottom to top, and then connecting the plurality of lifting rings with the extended screws in a threaded manner. The frame is then welded to the end, so that the screw elements cannot be removed from the frame. This presents several problems: firstly, the precision requirement of punching is high, with high costs, waste time and energy. Secondly, the screw piece can not be displaced in the mode, and during transportation and hoisting, the hoisting point may need to be changed under the influence of the installation environment or the dispatching equipment, for example, sometimes the hoisting point needs to be horizontally dispatched, sometimes the sign needs to be inclined by a certain angle for dispatching, and the dispatching can be rapidly completed. But the screw is spacing in the hole for current structure for it can not carry out position adjustment in a flexible way, can not be fine satisfies the operation demand, and the operation risk improves greatly.
