Abstract

A handle folding mechanism and a three-fold handle (48) and a cart using the same. The folding mechanism includes an intermediate assembly (1) and a pair of connection assemblies (2). The intermediateassembly (1) comprises a tubular outer casing (11), a pressure block (12) and an unlocking piece (13). The rear portion of the compact (12) extends through the front wall surface of the outer casing(11) into the outer casing (11) and is movable back and forth. The connecting assembly (2) includes a tubular housing (21) and a snap tab (22). The engaging piece (22) is slidably mounted in the housing (21). In the locked state, the front end of the engaging piece (22) penetrates into the outer casing (11). The unlocking piece (13) has a fixing portion. The fixing portion is provided with a freeend extending to the rear end of the pressing block (12) and the front end of the engaging piece (22).

Description

technical field [0001] The invention relates to a portable pushcart, in particular to a handle folding mechanism, a three-fold handle using the folding mechanism, and a pushcart with the three-fold handle. Background technique [0002] When using portable carts in daily life, in order to facilitate carrying and storage, and to save storage space, portable carts for various purposes generally adopt the method of folding in the horizontal direction (ie width) to reduce the size. When some carts are folded, the handle of the cart will be folded together with the body. This kind of situation often occurs on the handle across the frame. At present, this kind of handle can be folded through the horizontal folding mechanism according to actual needs. Realize two or three folds to minimize its volume. [0003] However, most of the horizontal folding mechanisms of existing handles use gear pairs, which leads to a large number of components, complex structures, and long assembly time...
