A linkage lock comprises a lock body, a linkage chain, and a lock mechanism arranged in the lock body. The linkage chain is formed via linking a plurality of link plates and has a first end joined with the lock body and a second end able to be inserted into and secured to a socket of the lock body. The lock body has a shaft. When intending to collect the linkage lock whose second end is unlocked, the user winds the linkage chain around the surface of the shaft with the shaft being a central axis to fold the linkage lock.

A folding chair includes a chair frame. The frame includes left and right side stands, front and rear cross supporting rod assemblies, seat rods, backrest rods and left and right side upright poles. Each side stand includes a front leg that leans backward and a rear leg that is coupled to the front leg and supports the front leg. The front or rear cross supporting rod assembly includes two front cross supporting rods. The seat rods are connected to the front legs, rear legs and upright poles. The backrest rods are connected to the rear legs. The upright poles are movably connected to the front legs.

PROBLEM TO BE SOLVED: To provide a foldable chair which can be folded into a small size in a chair of an L-shaped frame structure. SOLUTION: The foldable chair is provided with: a vertical frame member 10 extending in a vertical direction; a seat plate 50 supported at the intermediate position of the vertical frame member 10; and a base frame member 30 whose front end is connected turnably to the lower end of the vertical frame member 10. The base frame member 30 selectively takes an opening state position extending on a floor surface with a prescribed angle to the vertical frame member 10 extending in the vertical direction or a folded state position extending along the vertical frame member 10 at a position in front of the vertical frame member 10.

A notebook computer includes a connecting portion, a first display screen portion, a hinge structure and a computer mainframe. The first display screen portion has a first display surface. The hinge structure is pivotally connected to the connecting portion and the first display screen portion, respectively. The computer mainframe is slidably disposed on the connecting portion. The computer mainframe is slidable relative to the first display screen portion for alternatively changing arrangement orientations of the computer mainframe relative to the first display screen portion.

The invention relates to a modular large-array surface radar antenna mechanism. The modular large-array surface radar antenna mechanism comprises a first longitudinal rod and two second longitudinal rods, wherein a lead screw driving mechanism is arranged on the first longitudinal rod, the two second longitudinal rods are symmetrically arranged at two sides of the first longitudinal rod and are connected with the lead screw driving mechanism via a first connection rod, the first longitudinal rod is connected with the first connection rod via a second connection rod, and a plurality of oscillators are arranged on both of the first longitudinal rod and the two second longitudinal rods. In the antenna mechanism, by combination of the lead screw driving mechanism, the first connection rod andthe second connection rod, folding and unfolding of the antenna mechanism can be achieved, the antenna mechanism has the characteristics of large unfolding size and small folding size, the large powerrequirement of radar when the antenna mechanism is unfolded can be met, the requirement on high maneuverability and transportation performance of the radar when the antenna mechanism is folded is met, meanwhile, an antenna array surface with a relatively large size can be formed by combining a plurality of antenna mechanisms.

The invention discloses a stretching mechanism-supported double-side array large-area flexible solar cell wing. The stretching mechanism-supported double-side array large-area flexible solar cell wingcomprises a lifting mechanism, a stretching mechanism, two flexible solar cell arrays, pressing and releasing devices and box body unfolding and locking mechanisms; two ends of the top of the stretching mechanism are respectively connected with the two flexible solar cell arrays, and the bottom of the stretching mechanism is connected with the lifting mechanism; in an initial state, the two flexible solar cell arrays are symmetrical about the stretching mechanism; the stretching mechanism and the flexible solar cell array are each provided with a plurality of pressing points; and the pressingand release devices are arranged at the positions of the corresponding pressing points to press the stretching mechanism and the flexible solar cell arrays; the box body unfolding locking mechanismsare arranged at the connecting positions of the two ends of the top of the stretching mechanism and the first flexible solar cell array and the second flexible solar cell array and are used for unfolding the flexible solar cell arrays towards two sides in place and locking the flexible solar cell arrays. The stretching mechanism-supported double-side array large-area flexible solar cell wing has the advantages of small folding envelope, large unfolding area and stable unfolding configuration, and is suitable for a high-power spacecraft platform.

A moving carrier is disclosed. A lower-frame assembly includes a first moving member disposed on the guiding member, a second moving member disposed on the guiding member, an elastic member disposed corresponding to the guiding member, and a third moving member disposed on the second moving member. A transmitting member of a front-wheel assembly has a guiding groove. One end of the third moving member is disposed in the guiding groove. When the first moving member moves along the guiding member, the first moving member enables the elastic member to store a first energy. When the elastic member releases the first energy, the second moving member drives the third moving member to move and the third moving member pushes the guiding groove to move, so that the transmitting member can drive the front-wheel frame to move toward the lower-frame assembly.
