Combined framework profile for road traffic sign

Abstract

The invention discloses a combined framework profile for a road traffic sign. The profile comprises a first profile body and a second profile body which cooperate, the first profile body is provided with a lamp strip installing groove which is provided with an opening formed in the upper end and used for lighting an edge image and text part of the road traffic sign after a lamp strip is installed,and the first profile body and second profile body are detachably combined through sliding limiting mechanisms to produce the road traffic sign with the edge image and text part which needs to be lighted when the first profile body and second profile body are assembled and / or to produce the road traffic sign without the edge image and text part which needs to be lighted only using the second profile body when the first profile body and second profile body are not assembled. The framework profile has the advantages that the structure is simple and compact, assembling and changing can be flexibly achieved according to demands, the connecting stability is good, and the safety performance is high.

Description

technical field [0001] The invention mainly relates to the field of road traffic sign manufacturing, in particular to a frame profile for road traffic signs which can be combined. Background technique [0002] With the development of road traffic, the beautification of roads, and the improvement of traffic safety requirements, there are more and more applications of road traffic luminous signs. In the prior art, some traffic luminous signs adopt transparent sign panels, and reflective films with traffic instruction graphics are pasted on the front of the sign panels, and light source panels are arranged on the back of the sign panels, and the front can serve as normal indications during the daytime. Or the function of reflective indication in the dark, and at the same time, when the back of the night is illuminated, it can also transmit light so that the front can play the role of indication. [0003] In the prior art, some luminous traffic signs not only need to light up t...

AI Technical Summary

Problems solved by technology

The fixing effect of this structural form is not good, the inserted flange cannot form a solid connection with the frame, and since the flange cannot be seen, there is no way to find out where the two are not connected in place (for example, which surfaces are not connected to each other) Contact for compression, etc.) and improvement

This makes the connection unstable, and it is easy to cause structural problems of traffic signs. Whether it is transportation or high-altitude hoisting, it is easy to loosen or even fall off, which seriously threatens the safety of operations.

And because of the instability of this structure, even if no problems are found during installation, the risk of falling off is very likely to occur with the outdoor wind and rain of the traffic sign, which seriously affects the safety of pedestrians and vehicles on the road.

[0006] 3. The existing frame setting is unreasonable

The frame is then welded dead so that the screw pieces can no longer be removed from the frame

There are several problems: one is that the drilling accuracy is high, the cost is high, and time-consuming and labor-intensive

However, the existing structure cannot flexibly adjust its position due to the fact that the screw is limited in the hole, which cannot meet the operation requirements well, and the operation risk is greatly increased.
