Second-hand car information sharing system based on block chain

Abstract

A block chain-based second-hand car information sharing device disclosed by the present invention comprises a bottom plate, the upper surface of the bottom plate is fixedly connected with a hydraulic rod, the top end of the hydraulic rod is fixedly connected with a top plate, the upper surface of the top plate is slidably connected with a speed measuring device, and the lower surface of the top plate is rotatably connected with a supporting device. The invention relates to the technical field of vehicle detection equipment. According to the second-hand car information sharing system based on the block chain, by arranging the supporting device, when equipment is used, the two sides of a top plate are abutted by hydraulic rods, reinforcing ribs are fixed to the bottom of the top plate, screws are naturally perpendicular under the gravity effect, after the top plate moves to the designated height, sleeves are rotated, and the bottom ends of the sleeves abut against the ground under the thread effect; the middle of the top plate is fixedly supported by the sleeve and the screw and is matched with the guide device, kinetic energy generated by sudden descending of the equipment can be effectively absorbed, the living space of maintainers at the bottom of the top plate is increased, and the problem that traditional vehicle detection equipment is low in safety coefficient is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle testing equipment, in particular to a blockchain-based second-hand car information sharing system. Background technique [0002] With the development of social economy, people's living standards are also increasing day by day, and the requirements for all aspects of life are also getting higher and higher. The continuous increase in car ownership has promoted the growth of used car transactions, and the second-hand car market industry is also becoming more and more Hot; [0003] Before the traditional used car is traded, the vehicle needs to be inspected to facilitate the transparency of the information. For the inspection of the vehicle chassis, when the traditional inspection equipment lifts the vehicle, due to the single load-bearing mechanism, when the lifting device suddenly loses pressure, The maintenance personnel at the bottom have limited living space and are prone to danger.
