Abstract

The invention discloses a liquid nitrogen biological container with a multi-degree-of-freedom self-aligning rotating shaft structure, and belongs to the technical field of biological containers. The liquid nitrogen biological container comprises an inner container, the inner container is sleeved with a shell, a tray is arranged in the inner container, the tray is fixedly connected with a rotating shaft, the rotating shaft is provided with an inner aligning structure connected with the inner top wall of the inner container, the rotating shaft is sleeved with a tray shaft sleeve, the tray shaft sleeve is fixedly connected with the tray, and the tray shaft sleeve is provided with a bottom aligning structure connected with the inner bottom wall of the inner container; and an outer aligning structure connected with the shell is arranged on the part, outside the shell, of the rotating shaft. By arranging the inner aligning structure, the bottom aligning structure and the outer aligning structure, the coaxiality requirement in the product welding manufacturing process can be greatly lowered, and the coaxiality requirement is met by adjusting the position of the rotating shaft.

Description

technical field [0001] The invention belongs to the technical field of biological containers, and in particular relates to a liquid nitrogen biological container with a multi-degree-of-freedom self-aligning shaft structure. Background technique [0002] Liquid nitrogen is the liquid form of nitrogen gas formed at low temperature. Liquid nitrogen has a wide range of uses. It can quickly freeze food, make ice products, preserve living tissue, and conduct low-temperature physics research. Liquid nitrogen biological container refers to a biological container that utilizes the low temperature properties of liquid nitrogen to preserve biological samples. [0003] The structure of the existing liquid nitrogen biological container is mainly divided into three parts: the outer shell, the inner container (including the neck) and the cryopreservation tray. The inner container is filled with liquid nitrogen to provide a temperature field for cryogenic storage, and the cryopreservation ...
