[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a traffic display screen mounting bracket, which has the following beneficial effects:

[0021] When the U-shaped baffle no longer limits the second clamping block, the compressed third spring will provide an elastic force to the second clamping block, so that the second clamping block can extend out of the second empty slot. At this time, the second clamping block will enter the second clamping slot. Through the cooperation between the second clamping block and the second clamping slot, one end of the adapter seat can be fixed in the positioning slot, so that the adapter seat and the positioning seat can be assembled.

[0022] Pressing the pressing block can make the positioning plate slide a certain distance in the first empty slot. At this time, the second positioning block will compress the second spring inside the second cavity, so that the first clamping block can be separated from the first clamping slot. At this time, pulling or pushing the support rod can make the support rod slide inside the guide slot, so as to temporarily adjust the distance between the main body of the traffic display screen and the column, and it is convenient to temporarily adjust the position of the main body of the traffic display screen. At this time, there is no need to reinstall the first clamping sleeve and the second clamping sleeve and other parts, nor is there any need to replace the supporting components of the main body of the traffic display screen. The limitation during use is low, which makes the main body of the traffic display screen more convenient to install;

[0023] By pulling the limit plate through the toggle block, the first positioning block will stretch the first spring in the first cavity, and further enable the limit rod to be pulled out at the through hole. At this time, the two support rods can be synchronously tilted to a certain height, so that the height of the limit frame can be temporarily adjusted, thereby facilitating the temporary adjustment of the height of the traffic display screen body.

[0038] First, insert one end of the adapter 20 into the interior of the positioning groove 21. At this time, the adapter 20 will provide a pressure to the protrusion 39, so that the third positioning block 38 can provide a pressure to the fourth spring, so that the fourth spring can be compressed. In this process, the U-shaped baffle 36 will slide in the third empty groove 35. When the U-shaped baffle 36 no longer limits the second clamping block 32, the compressed third spring will provide an elastic force to the second clamping block 32, so that the second clamping block 32 can extend out of the second empty groove 33. At this time, the second clamping block 32 will enter the second clamping groove 34. Through the cooperation between the second clamping block 32 and the second clamping groove 34, One end of the adapter 20 can be fixed in the positioning groove 21, so that the adapter 20 and the positioning seat 19 can be assembled.
