The invention discloses a locking mechanism, which comprises a frame capable of being folded or unfolded and a seat frame arranged on the frame and used for installing a seat part. A supporting blockcapable of supporting the seat frame is rotationally connected to the frame; the seat frame is slidably connected to the supporting block; the seat frame is further rotationally connected with the frame, slides on the supporting block when the frame is folded and rotates relative to the frame along with the supporting block to be folded. A pressure locking device is arranged between the supportingblock and the seat frame and can lock the supporting block and the seat frame when the pressure locking device is pressed so as to limit folding of the frame. The pressure locking device is used forbeing arranged below the seat part and being pressed to act when a baby or an animal or other heavy object exist on the seat part. When a baby or an animal sits or lies on the seat part of the unfolded frame, the seat frame and the supporting block are mutually locked through the pressure locking device, the folding function of the frame is limited by limiting the degree of freedom of the seat frame, the situation that the frame is folded and collapsed due to the fact that the folding function of the frame is unlocked carelessly or mistakenly is avoided, and use is safe and reliable.

    本发明公开了一种锁定机构,包括可收折或展开的车架和设在车架上的用于安装坐部的座架,车架上转动连接有能支撑座架的支撑块,座架滑动连接在支撑块上,座架还与车架转动连接并在车架折叠时在支撑块上滑动并随支撑块相对车架转动进行收折,支撑块和座架之间设有在受压时能将支撑块和座架二者锁定从而限制车架折叠的压力锁定装置,压力锁定装置用于设置在坐部下方并在坐部上有婴儿或动物等重物时受压而作用,使展开的车架的坐部上坐有或卧有婴儿或动物时,压力锁定装置将座架和支撑块相互锁定,通过限制座架的自由度从而限制车架的折叠功能,避免在大意或者误操作下解锁车架的折叠功能而导致车架发生折叠垮塌的情况发生,使用安全可靠。
