Abstract

The invention provides a locking mechanism, and a folding seat and a folding wheelchair using the locking mechanism. The locking mechanism only needs a same power source for unlocking and locking; unlocking, folding, unfolding and locking of the folding seat and the folding wheelchair only need the same driving force, the locking mechanism has the advantages of being ingenious in design, simple instructure and the like, the locking mechanism comprises a fixing piece and a telescopic rod piece, and a left mounting hole and a right mounting hole are formed in the fixing piece; the telescopic rod piece comprises a center rod and two telescopic rods installed at the two ends of the center rod. The telescopic rod can move in the length direction of the center rod. An elastic piece is installedbetween the two telescopic rods, lock pins are arranged at the opposite ends of the two telescopic rods, a sleeve is connected to the center rod, pushing pieces are connected to the two ends of the sleeve, the two lock pins are sleeved with the pushing pieces, and the pushing pieces are in a V shape or a trapezoid shape.

Description

technical field [0001] The locking mechanism of the present invention particularly relates to a locking mechanism that can be unlocked and locked only by the same driving source.
