The utility model provides a kind of portable telescopic support, including support main body, foot support component, drive assembly and first locking assembly, support main body includes shell body, telescopic rod and auxiliary cavity;Foot support component includes at least three feet;Drive assembly includes axial drive assembly, axial drive assembly includes first energy storage unit;First locking assembly includes locking element, locking element includes first buckle, foot includes first clamping groove;First buckle and first clamping groove buckle to switch to locking state, foot is housed in auxiliary cavity with condensing state, first energy storage unit is under pressure energy storage;When the locking element and the foot move in the direction of engagement relative, the first buckle can exit the first clamping groove to release lock, first energy storage unit instantaneously releases elastic potential energy and drives foot to at least partially pop out auxiliary cavity.The utility model is by the cooperation of first locking assembly and axial drive assembly, realize the storage and automatic pop-up of foot.

The utility model discloses a kind of electric connector and connector assembly, belong to electric connector field, a kind of electric connector, including shell, locking piece, conducting terminal, lock catch, and draw belt, the inside of shell is equipped with several conducting terminals, conducting terminal has limit part, locking piece is installed in shell, and it is inserted into shell and with the end wall of limit part abuts and / or close setting, to keep conducting terminal in required position, at least one side wall of shell has lock catch, draw belt is connected with lock catch through locking piece.This electric connector and connector assembly of the utility model, through the draw belt that locking piece is connected lock catch avoids shell complex structure to open, enhance protection, simplify structure, optimization layout, benefit miniaturization integration, and make locking piece have limit and draw belt wear function, realize the collaborative operation of multiple functions, substantially improve comprehensive performance.

The application discloses a folding rocking chair, which comprises a gear seat, a gear block, a locking block, an unlocking handle, a safety mechanism and a rocking lever for supporting a carrier. The gear seat is provided with a locking groove for cooperating with the locking block to realize folding locking of the rocking lever. The unlocking handle is in transmission connection with the gear block, and is used for driving the gear block to be accommodated in an accommodation cavity of the gear seat to adjust the gear of the rocking lever. The unlocking handle is also in transmission connection with the locking block, and is used for driving the locking block to avoid the rocking lever to make the rocking lever enter or leave the locking groove. The safety mechanism is used for limiting the movement of the unlocking handle, and can remove the movement limitation of the unlocking handle under the driving of external force. The safety mechanism and the unlocking handle are matched with each other to form two safety locks, which can prevent the folding rocking chair from being unlocked by mistake during use, and greatly improve the safety and reliability of the folding rocking chair.

The embodiment of the application provides a baby carriage, and relates to the technical field of baby carriages. The baby carriage comprises a frame and a seat installed on the frame. The frame is locked in an unfolded state by a locking mechanism. The locking mechanism comprises a locking groove arranged on a push handle and a locking block arranged on a base. The seat bottom is provided with at least one protruding part. When the seat is rotated from the unfolded position to the folding direction relative to the frame, the protruding part contacts and applies a driving force to the locking block, so that the locking block is separated from the locking groove, thereby linkage unlocking of the frame during folding of the seat is realized, and one-step folding operation is achieved. The end of the protruding part is provided with an abutting inclined surface, so that the seat can avoid the locking block when being turned back to unfold from the folded state, and mislocking is prevented. The seat can be installed in a forward direction or a reverse direction, the locking block is driven by different protruding parts, and the generality is high. The application simplifies the operation steps, and improves the convenience and safety.
