Description

Technical Field

[0001] The present invention relates to the field of low-temperature storage technology, in particular to a cabinet door sealing mechanism and a low-temperature automated warehouse. Background Art

[0002] The storage of biological samples, vaccines, etc. requires an ultra-low temperature environment to ensure the stability and storage time of biological samples. In an ultra-low temperature environment, the storage of biological samples requires the use of automated retrieval equipment. In order to ensure the normal operation of the automated retrieval equipment and reduce the energy consumption of the ultra-low temperature storage area, the biological sample storage cabinet needs to be well sealed to prevent the cold air from leaking out of the ultra-low temperature storage area.

[0003] In the prior art, a storage cabinet with a top door that has a better sealing effect has a top sealing structure. This structure has a good sealing effect, but requires a larger space for biological sample removal operations.

[0004] The sealing effect of storage cabinets with side sliding doors is poor, and the leakage of cold air in the low-temperature refrigerated area will cause external equipment operation failure and increase energy consumption. Summary of the invention

[0005] The object of the present invention is to provide a cabinet door sealing mechanism and a low-temperature automated warehouse to solve the problems raised in the above-mentioned background technology.

[0006] The cabinet door sealing mechanism comprises:

[0007] Storage cabinets and door mechanisms mounted on the storage cabinets;

[0008] A sealed door mounted on the cabinet door mechanism;

[0014] Furthermore, the sealed door includes a door panel, and a door opening mechanism is arranged at the front end of the door panel for other mechanisms to drive the sealed door to rise and fall.

[0015] Furthermore, a guard plate is provided between the upper and lower adjacent sealing doors to reduce the collision and wear between the sealing doors.

[0016] Further, the locking mechanism comprises:

[0017] A locking pressure plate arranged on the outside of the sealing door and pressing the sealing door;

[0018] Eccentric mechanisms arranged at both ends of the locking pressure plate;

[0019] One end of the eccentric mechanism is connected to the bearing seat through a rotating shaft, and the other end is connected to an electric push rod. Under the push of the electric push rod, the locking pressure plate can rotate around the rotating shaft to achieve compression of the sealing door.

[0020] Furthermore, the electric push rod and the bearing seat are connected to the mounting seat via a connecting seat.

[0021] A low-temperature automated warehouse comprises the above-mentioned cabinet door sealing mechanism.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] First, the door of the low-temperature storage cabinet of the present invention is opened and closed by sliding up and down, and a maneuverable space is reserved at the top of the door unit. The door of any layer can be pushed upward to open the door, and the door closing process can be automatically realized by gravity, which reduces the complexity of the door opening and closing action and the space required for the door opening and closing;

[0024] Second, the sealed door is equipped with a sealing strip, and the door frame is equipped with a matching labyrinth groove, which improves the sealing of the door and reduces the energy consumption of the cold storage;

[0025] Thirdly, a locking mechanism is designed which uses an electric push rod as power.
