Description

Storage pedal step of liquid nitrogen tank Technical Field The utility model relates to the technical field of liquid nitrogen tanks, in particular to a storage pedal step of a liquid nitrogen tank. Background In the fields of biomedicine, material science and the like, a liquid nitrogen tank is widely applied as low-temperature storage equipment for storing biological samples, cells, vaccines, special materials and the like, and because the tank body of the liquid nitrogen tank is usually higher in height, and in order to ensure good low-temperature storage effect, the opening position of the liquid nitrogen tank is often designed at the top of the tank body. When the articles at a higher position in the liquid nitrogen tank are required to be taken or placed, due to the limitation of height, when an operator stores the articles in the liquid nitrogen tank in the actual operation process, the operator often needs to stand on the tiptoe and bend down, the operation is inconvenient, additional tools such as stools and the like are often required to be used, however, the articles are easy to fall down in the operation process, large potential safety hazards exist, the articles are inconvenient to use and store in a relatively narrow working area around the liquid nitrogen tank, the technical problems are solved, the operation convenience in the process of storing the articles in the liquid nitrogen tank is improved, and in view of the problems, the storage foot step of the liquid nitrogen tank is provided. Disclosure of utility model The utility model aims to solve the defects in the background art and provides a storage pedal step of a liquid nitrogen tank. In order to solve the technical problems, the utility model adopts the following technical scheme: the step is stepped on to liquid nitrogen container storing, includes: The two side frame plates are symmetrically arranged at the outer wall of the liquid nitrogen tank body, and a first horizontal pressing plate and a second horizontal pressing plate are fixedly connected between the upper end and the lower end of each side frame plate respectively; the pedal step comprises a first stage step plate and a second stage step plate which are respectively rotatably arranged at the lower sides of the first horizontal pressing plate and the second horizontal pressing plate; The storage unit comprises a storage support box inserted on the side frame plate at any side, and an outer baffle is fixedly arranged at the outer end of the storage support box. Preferably, the storage unit comprises an L-shaped supporting plate which is symmetrically arranged and detachably arranged on the second horizontal pressing plate, and a sliding rail is arranged on the L-shaped supporting plate; the storage support box is provided with a sliding block which is arranged on the sliding rail in a sliding way. Preferably, the two sides of the bottom end of the storage support box are provided with caulking grooves for detachably mounting the sliding blocks. Preferably, the inner end side of the storage support box is fixedly provided with a convex block, a clamping plate is inserted into the convex block, and the clamping plate is used for preventing the storage unit from derailing. Preferably, a rubber pad sleeve is sleeved on the outer edge of the L-shaped supporting plate, and a handle is arranged on the outer baffle plate. Preferably, a connecting rod is rotatably arranged between the outer ends of the primary step plate and the secondary step plate. Compared with the prior art, the utility model has the beneficial effects that: 1. The storage foot step of the liquid nitrogen tank provides a step design outside the liquid nitrogen tank body, which is beneficial to improving the operation efficiency and convenience of taking and placing articles in the liquid nitrogen tank; 2.
