The utility model relates to a household appliance technology. The utility model particularly relates to a refrigerator. The refrigerator comprises a refrigerator body and a door body, the door body comprises a door shell, a first end cover, a second end cover and an inner container, the first end cover comprises a first cover body part and a first extending part, and the first extending part extends towards the bottom end and is attached to the inner surface of a first side wall and the inner surface of a second side wall; the door shell further comprises a first bending limiting structure, the first bending limiting structure is arranged on the edge, away from the front panel, of the first side wall and / or the second side wall, the first bending limiting structure is bent towards the interior of the foaming cavity and abuts against the edge of the first extending part, so that the first extending part is clamped between the first side wall and the first bending limiting structure, and / or the first bending limiting structure is bent towards the interior of the foaming cavity and abuts against the edge of the second extending part. The first extension part is clamped between the second side wall and the first bending limiting structure, so that the first side wall and / or the second side wall are / is prevented from loosening relative to the first extension part in the direction far away from the foaming cavity. According to the refrigerator provided by the invention, the risk of bubble leakage of the door body can be reduced.

The application provides a kind of mitochondrial function optimization additive for cell culture, preparation method and application, belong to cell culture technical field.The additive includes core active ingredient, auxiliary component and carrier, and the core active ingredient includes D-Arg-Cha-Lys-Phe-NH2 Polypeptide, ubiquinone-10 phosphate, reduced glutathione and alpha-lipoic acid.The application forms a multi-target core active system through the synergy of the four, realizes the triple synergistic protection of stabilizing mitochondrial cardiolipin, maintaining mitochondrial morphology and membrane potential, and reducing mitochondrial ROS, which can significantly improve cell culture quality.When applied, the mitochondrial cardiolipin content can be increased by more than 50%, the mitochondrial abnormality ratio can be reduced to less than 12%, the membrane potential positive cell ratio can be increased to more than 86%, the mitochondrial ROS level can be reduced by more than 40%, and the cell proliferation rate can be increased by more than 25%, which is suitable for in vitro culture of various eukaryotic cells, and the preparation process is simple and has no cytotoxicity.

The utility model discloses a crusher screen quick release structure which comprises a shell, a pair of screens arranged in the shell and a screen frame arranged on the outer sides of the screens and used for pressing the screens, the lower end of the screen frame is hinged to the bottom of the shell, and a lock catch is arranged on the upper edge of the screen frame. A shifting fork capable of hooking the lock catch through swinging is further arranged in the shell, and a driving mechanism for driving the shifting fork to swing is arranged outside the shell. The shifting fork is driven by the driving mechanism to swing, so that the shifting fork hooks the screen lock catch to form a self-locking structure, the screen frame is fixed, and the screen is compressed.

The utility model discloses a plane type self-locking handle for a drawer, which belongs to the technical field of furniture parts and comprises a handle frame, a turning cover is arranged in the handle frame, one side of the turning cover is connected with a turning structure, and the lower portion of the turning structure is connected with the bottom wall of the handle frame. According to the plane type self-locking handle for the drawer, the turnover structure drives the turnover cover to automatically turn over and keep vertical, the turnover cover is embedded in the handle frame to form a plane structure, and therefore a hidden handle structure can be formed, the overall attractiveness is guaranteed, and the problem of dust accumulation is not prone to occurring; the inclined plane of the adjusting lock catch and the inclined plane of the fixed lock catch extrude to enable the adjusting lock catch to move upwards and pass through the fixed lock catch smoothly, then the spring drives the piston to reset downwards, the adjusting lock catch and the fixed lock catch are locked, the purpose of self-locking of the drawer is achieved, in the opening process, the flip cover needs to be pushed open, the air bag needs to be pressed, and therefore the function of preventing children from opening the drawer by mistake can be achieved.
