Problems solved by technology

[0003] In the prior art, the sealing effect is better when the top door of the storage cabinet adopts a top-sealed structure, which has a good sealing effect, but requires a large space for the biological sample taking operation
[0004] Storage cabinets with side-mounted sliding doors have poor sealing effect, and the leakage of cold air in the low-temperature refrigeration area will cause external equipment to malfunction and increase energy consumption

Embodiment 1

[0044] In this embodiment, the contact position between the rear end of the airtight door 4 and the cabinet door frame 21 is a cuboid structure, and the bottom and side surfaces of the cuboid structure are respectively provided with a sealing strip 42 with an "L"-shaped cross section. Close to the setting, the cabinet door frame 21 is provided with a labyrinth groove 212 matching the "L" shaped sealing strip 42 .

[0045] The airtight door 4 includes a door panel 41, and the front end of the door panel 41 is provided with a door opening mechanism 43 for driving the airtight door 4 up and down by other mechanisms. Manipulators can be set to drive the airtight door 4 up and down. In the process of opening the door, wear may occur between the airtight doors 4, and guard plates 44 are set between adjacent airtight doors 4 to reduce the wear of the airtight doors 4.

Embodiment 2

[0047] In this embodiment, the locking mechanism 3 includes a locking pressure plate 31, a bearing seat 32, a connecting seat 33, an electric push rod 34, a rotating shaft 35, an eccentric mechanism 36, and a mounting seat 37, wherein the outer side of the sealing door 4 is provided with a pair of sealing doors. 4. The locking pressing plate 31 that plays a pressing role; the two ends of the locking pressing plate 31 are equipped with an eccentric mechanism 36; one end of the eccentric mechanism 36 is connected to the bearing seat 32 through the rotating shaft 35, and the other end is connected to the electric push rod 34. Pushed by the push rod 34 , the locking pressing plate 31 can rotate around the rotating shaft 35 to realize the compression of the airtight door 4 . The electric push rod 34 and the bearing seat 32 are connected to the mounting seat 37 through the connecting seat 33 .

[0048] In this example, refer to Figure 7 , Figure 8 , the structure of the eccentri...

Embodiment 3

[0050] In this embodiment, a low-temperature automated warehouse 5 includes a cabinet door sealing mechanism, the storage cabinet 1 is arranged inside the low-temperature automated warehouse 5, and the cabinet door mechanism 2 is connected and fixed with the low-temperature automated warehouse 5 through a connecting component; the locking mechanism 3 is provided The upper and lower mounting bases 37 are connected to the low-temperature automated warehouse 5 through the mounting bases 37 .

Abstract

The invention relates to the technical field of low-temperature storage, and provides a cabinet door sealing mechanism which comprises a storage cabinet and a cabinet door mechanism installed on the storage cabinet, a sealing door arranged on the cabinet door mechanism, and a locking mechanism used for keeping a locking relationship between the sealing door and the cabinet door mechanism. According to the low-temperature storage bin cabinet, the cabinet doors are opened and closed in an up-down sliding mode, the motorized space is reserved in the tops of the cabinet door units, the cabinet door of any layer can be selected to be pushed upwards, the door opening and closing process can be automatically achieved through the gravity effect, and the cabinet door opening and closing action complexity and the cabinet door opening and closing space are reduced; a sealing strip is arranged on the sealing door, and a matched labyrinth groove is formed in the cabinet door frame, so that the sealing performance of the cabinet door is improved, and the energy consumption of the refrigeration house is reduced; the locking mechanism adopting the electric push rod as power is designed, the electric push rod is converted into the pressure of the locking pressing plate on the sealing door through the eccentric mechanism, and the advantages of being easy to control, good in locking effect and low in cost are achieved.

Description

technical field [0001] The invention relates to the technical field of low-temperature storage, in particular to a cabinet door sealing mechanism and a low-temperature automatic warehouse. Background technique [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 the ultra-low temperature environment, the storage of biological samples requires the use of automatic retrieval equipment. In order to ensure the normal operation of the automatic 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 ultra-low temperature storage area from being damaged. Air conditioning leaks. [0003] In the prior art, the better sealing effect is that the top door of the storage cabinet adopts a top-sealed structure, which has a better sealing effect, but requi...
