Reinforcing and locking device for vehicle frame

摘要

A reinforcing and locking device for vehicle frame includes a reinforcing component (2), a connecting component and an eccentric locking component, the vehicle frame comprises a beam (1) and a seat tube (3). The beam (1) can be folded into at least two segments (11, 12). A hinge axle (81), through which various segments of the vehicle beam (1) are hinged with each other, is provided vertically. The reinforcing component (2) is connected to the beam (1) and the seat tube (3). The seat tube (3) is provided with a connecting component. A front end of the reinforcing component (2) is hinged with a front segment (11) of the beam (1), and a rear end of the reinforcing component (2) is connected with the seat tube (3) through the connecting component. The reinforcing and locking device for vehicle frame has good stability, simple structure and low cost.
