The invention discloses a handle-free automatic locking folding joint, which is arranged on a disconnection part of a pipe. The handle-free automatic locking folding joint comprises a first joint and a second joint which are connected with a first section and a second section of the pipe respectively, wherein the first joint is hinged with the second joint through a hinge on one side; the first joint comprises a locking block, a locking block swing mechanism and a locking block swing actuating mechanism; the locking block is positioned in a first joint shell; the locking block swing mechanismcan be used for enabling the locking block to swing around a rotating shaft which is perpendicular to the axis of the pipe; the locking block swing actuating mechanism can be used for getting the swing of the locking block under elastic control; the top of the locking block comprises a convex edge which extends in the swing direction of the locking block; the second joint comprises an opening at a position corresponding to the position of the locking block in the first joint; and the opening comprises a structure which enables the top of the locking block to penetrate through and the convex edge to be clamped on the outer edge of the opening after the top of the locking block penetrates through. Through the folding joint, the volume of a folded frame is further reduced, so that the strength of the folding joint is further enhanced; and the folding joint can be automatically locked, so that the folding joint is more convenient and labor-saving in operation.
Description
technical field [0001] The invention relates to a folding joint, in particular to a handle-less automatic locking folding joint. Background technique [0002] With the development of bicycle technology, people's requirements for bicycles have evolved from the original means of transportation to a travel tool that combines transportation, leisure, and exercise. Under this situation, folding bicycles have become a trend as products that can meet the above-mentioned requirements. The folding joints of existing folding bicycles, no matter on the main beam tube of the vehicle frame or on the standpipe, no matter whether its specific form is four-link or cam locking, or V-shaped blocks, or other forms, In the process of opening and locking, it must be operated by the handle, so the operation is cumbersome and laborious. [0003] figure 1 is a typical example of an existing folded joint. This folding joint includes the front and rear joints 2a and 4a hinged on the hinge 3a and ...
