Abstract:
A detachable framework for an electric cart, comprising a first chassis part, a second chassis part, and connecting pin;said first chassis part including a steering handle mounted at a front end thereof for controlling a moving direction of a front wheel, a connecting beam provided at a lower rear end thereof, and a connecting pin receiver upward extended from a middle point of said connecting beam;said second chassis part having two rear wheels connected to two lateral sides thereof and a driving mechanism mounted thereon, said second chassis part including two receiving heads formed at two lower front ends thereof for correspondingly receiving two lateral ends of said connecting beam of said first chassis part, a supporting post upward extending from a middle front of said second chassis part and having a first positioning screw turnably mounted to a front wall thereof, and a seat post located in front of and above said supporting post together with said connecting pin receiver of said first chassis part form a continuous hollow channel when said first chassis part is connected to said second chassis part; andsaid connecting pin being slidably received in said hollow channel formed by said seat post and said connecting pin receiver with a seat connected to a top thereof; and said seat post being provided at a front wall with a second positioning screw that may be turned to extend into said seat post and tightly press against said connecting pin;whereby when said first positioning screw on said supporting post of said second chassis part is turned to extend from said supporting post and tightly press against a rear wall of said connecting pin receiver and said second positioning screw on said seat post of said second chassis part is turned to tightly press against said connecting pin in said seat post, said first and said second chassis parts are subjected to a forward and a backward force acted on the same straight line at the same time by said first and said second positioning screw, respectively, to cause them firmly associate with one another without the possibility of shifting sideward relative to one another.
