As for the fixing method of the two frame rods 11 of the same frame 1, the fixing by the elbow 2 and/or the fixing by the edge covering rod 5 as described below may be adopted, or the fixing may be directly carried out by a screw, and the two frame rods 11 may be assembled detachably.

When needs are maintained, will originally splice two frame poles 11 dismantles and separates together fixed, and what this moment just can relax takes off the spacing light source board subassembly 4 of chucking originally and maintains. The panel assembly 3 originally fixed on the frame rod 11 does not need to be taken down, and can continuously keep fixed connection with the frame rod 11, namely, the panel and the reflective film on the panel assembly 3 cannot be damaged. Through the special design, the following technical advantages are achieved:

firstly, the utility model discloses a two-sided luminous road traffic sign, pioneering nature will be originally frame 1 design to constitute by two detachable concatenations of frame pole 11, the special construction design of frame pole 11 makes both mutually support and has formed first slot portion 14, second slot portion 15, this makes when the installation preparation, two light source board subassemblies 4 all can utilize slot portion just to realize spacing fixed, need not other fixed subassembly, the manufacturing cost has been saved greatly, the production technology has been simplified greatly.

Secondly the utility model discloses a two-sided luminous road traffic sign, the frame 1 that will be originally one of pioneering nature designs into by two detachable concatenations of frame pole 11 and forms, and this makes when maintaining in the later stage, will splice two fixed frame poles 11 together originally and dismantle and separate, and what just can relax takes off the spacing light source plate subassembly 4 of chucking originally and maintains. The panel assembly 3 originally fixed on the frame rod 11 does not need to be taken down, and can continuously keep fixed connection with the frame rod 11, namely, the panel and the reflective film on the panel assembly 3 cannot be damaged. This greatly reduces the difficulty of maintenance and the cost of replacement. The attractive degree and traffic indication effect of the indicator are effectively guaranteed. And this kind of dismantlement maintenance mode for dismantle the light source board and become more simple and convenient swift, maintenance time shortens greatly, has shortened the drop into service latency again of sign, promotes greatly to road traffic instruction security.

As shown in fig. 1 to 5 and 10, further, in a preferred embodiment, the frame rods 11 include hollow tubes 16 arranged along an axis, an outer side of each tube 16 is used for bearing and fixing the panel assembly 3, the bosses 12 are disposed on an inner side of each tube 16, two adjacent frames 1 are connected by the elbows 2, two ends of each elbow 2 are provided with two limiting blocks 21 protruding outwards, and the two limiting blocks 21 are respectively inserted into the two tubes 16 of the adjacent frame 1 to form limiting connection with the frame 1 and to form splicing limiting for the two frame rods 11 of the frame 1. That is, the elbow 2 achieves two functions: firstly, when being the connecting piece of two adjacent frames 1, owing to insert respectively in the cavity body 16 of two adjacent frames 1 through totally four stoppers 21 at both ends for two frames 1 connect firmly, have constituted the whole frame structure of sign. Secondly because the utility model discloses the frame 1 that will originally be pioneering nature is designed into to constitute by the detachable concatenation of two frame poles 11, inserts simultaneously through two stoppers 21 with 2 one ends of elbow in the cavity body 16 that belongs to two frame poles 11 of same frame 1 for these two frame poles 11 are connected firmly, and only need pull down elbow 2, have and can make two frame poles 11 separate at once, are convenient for change and maintain light source board subassembly 4. The connection stability and the disassembly convenience are well considered.

In this embodiment, all be equipped with fixed screw hole on the stopper 21, be convenient for insert the back and further form detachable fixed connection with stopper 21 and body 16 through the screw.
