The invention discloses a folding frame and a folding bicycle. The folding frame comprises a cross beam, a stand column and a supporting column. The cross beam comprises a front beam and a rear beam;the rear end bottom of the front beam and the front end bottom of the rear beam are rotatably connected so that the front beam and the rear beam can be vertically folded and cannot automatically rotate to be folded in the riding process. One end of the supporting column is rotatably connected to the stand column, the other end of the supporting column is detachably connected to the front beam through an inserting mechanism and is supported below the front beam, the cross beam, the stand column and the supporting column are in a triangular shape, and the stability of the whole frame can be guaranteed. The inserting mechanism comprises a wrenching piece, a connecting rod and an inserting module, the wrenching piece is rotatably connected to the supporting column, two ends of the connecting rod are rotatably connected to the wrenching piece and the inserting module respectively, the inserting module is slidably connected to the supporting column in the axial direction of the supporting column, and the wrenching piece, the connecting rod and the inserting module form a crank slider mechanism; the inserting module can slide to be inserted into the front beam by applying acting force tothe wrenching piece, the operation is easy, and use is convenient.

    本发明公开了一种折叠车架及折叠车。折叠车架包括横梁、立柱及支撑柱;横梁包括前梁和后梁;前梁的后端底部与后梁的前端底部转动连接以使二者能够竖向折叠,在骑行过程中不会自行发生旋转而折叠;支撑柱的一端与立柱转动连接,支撑柱的另一端通过插接机构与前梁可拆卸式连接、并支撑在前梁的下方,横梁、立柱及支撑柱呈三角形状,可以保证整个车架的稳定性;插接机构包括扳动件、连杆及插接模块,扳动件与支撑柱转动连接,连杆的两端分别与扳动件及插接模块转动连接,插接模块沿支撑柱的轴向滑动连接于支撑柱,扳动件、连杆及插接模块形成曲柄滑块机构;对扳动件施加作用力即可使得插接模块滑动实现与前梁的插接,操作简单,方便使用。
