Abstract

The invention discloses a secondary locking mechanism which is used for locking a locking part of a first locking mechanism in a foldable frame. The secondary locking mechanism comprises a shell body, a clamping part, an operating part and a first elastic part, wherein the clamping part is connected with the shell body in a pivot mode, a clamping portion is arranged on the clamping part, when the foldable frame is unfolded, the clamping portion abuts against the locking part to lock the locking part, the operating part is connected with the clamping part, part of the operating part is exposed, the operating part is operated to control the clamping part to carry out movement so as to enable the clamping portion to be separated from the locking part, and the first elastic part provides reset elastic force for the clamping part. Compared with the prior art, the secondary locking mechanism can lock the locking part in the first locking mechanism of the foldable frame, achieve secondary locking of the foldable frame, can effectively prevent the phenomenon that the frame is accidentally folded in the process of use from happening, and is safe and reliable. When the foldable frame is folded, only the operating part needs to be controlled to move the clamping part to unlock the locking part, and operation is convenient. The invention further discloses the corresponding foldable frame.

Description

technical field [0001] The invention relates to a collapsible vehicle frame, in particular to a collapsible vehicle frame with a secondary locking mechanism therein. Background technique [0002] In order to facilitate placement and transportation, the current frame or seat is equipped with a frame folding device, through which the front and rear feet of the frame or seat can be folded together, so that the frame or seat Folding up saves space and is convenient for transportation. However, in order to prevent accidental folding during use, the frame folding device includes a front foot, a rear foot, a handle, a first locking mechanism and a second locking mechanism, and one end of the front foot is fixed with a One end of the first rotating member and the rear foot is fixed with a second rotating member, and one end of the handle is fixed with a third rotating member, the first rotating member and the second rotating member are pivotally connected by a first rotating shaft, ...
