The street lamp with shock absorbing and buffering function according to claim 1, wherein: the top of third buffer spring (20) and stopper (12) fixed connection, the bottom and the hollow cylinder (14) fixed connection of third buffer spring (20), the top and the hollow cylinder (14) fixed connection of fourth buffer spring (22), the bottom and mounting panel (21) fixed connection of fourth buffer spring (22).
5. A method of buffering a street lamp having a shock absorbing and buffering function according to any one of claims 1 to 4, comprising the steps of:
1) The street lamp base (1) is inserted into a pre-dug foundation pit to generate downward impact, the street lamp post (4) can impact downwards due to inertia factors, the upper connecting column (17) can move downwards due to impact force, and the impact can be relieved for the first time by the third buffer spring (20) outside the upper connecting column (17);
2) The impact after the first time of release is released for the second time through a second buffer spring (19), and then is led into the lower connecting column (17), wherein the fourth buffer spring (22) outside the lower connecting column (17) releases the impact for the third time;
3) The impact relieved for the third time is led into the damping device (23) through the mounting plate (21), the damping device (23) stretches and damps through the rubber outer cover (24), and meanwhile, the volume of a closed cavity in the rubber outer cover (24) changes along with the damping device, so that pressure gas (28) in the closed cavity is compressed or expanded, and the fourth damping effect is achieved;
4) When in windy weather, the street lamp pole (4) can be blown by wind to shake, and the impact generated by shaking can be transmitted to the first buffer spring (13) through the curved push plate (11) and the movable column (10), so that the shaking impact generated by blowing can be relieved by the first buffer spring (13).
