The invention discloses a self-locking mechanism of a non-bearing U-shaped traction trailer. The self-locking mechanism comprises an L-shaped self-locking base, an L-shaped assembling plate, an assembling block, a rotating shaft, an unlocking self-locking clamping plate, two first spring seats, a first guide sleeve, a second guide sleeve, an unlocking self-locking clamping seat, an unlocking conduction shaft, a self-locking inner shaft, an unlocking conduction plate, two conduction ejection pieces, two second spring seats, a reset tension spring, a pressure spring, an unlocking plate and an unlocking hole. The L-shaped assembling plate is fixedly installed on the outer side wall of the L-shaped self-locking base, the assembling block is fixedly installed on the inner side wall of the L-shaped self-locking base, the unlocking self-locking clamping plate is hinged to the top of the assembling block through the rotating shaft, two first spring seats are symmetrically installed on the twoside edges of the assembling block, and the second guide sleeve is installed in the first guide sleeve in a sliding mode. The self-locking mechanism has the self-locking function, the purpose of quickly disassembling and assembling a non-bearing U-shaped vehicle hopper can be achieved, and the working efficiency can be effectively improved.
