Refrigeration container sealing device capable of avoiding sealing damage caused by extrusion

Abstract

The invention relates to the technical field of cold chain systems, and discloses a refrigeration container sealing device capable of avoiding sealing damage caused by extrusion. The refrigeration container sealing device comprises a rack, a movable tank is formed in the rack, an elastic cavity is movably connected to the interior of the movable tank, a magnetic block is fixedly connected to the interior of the elastic cavity, an electromagnetic rod is fixedly connected to one end, away from the magnetic block, of the elastic cavity, an exhaust pipe is fixedly connected to a side surface of the elastic cavity, a spring bag is fixedly connected to one end, away from the elastic cavity, of the exhaust pipe, an elastic cavity is subjected to pressure of a push rod under the influence of pressure on a rack, air in the elastic cavity enters a first rack, a metal contact lever in the first rack is mutually connected with a metal strip, an air pump starts to work, a sealing device can be automatically triggered, a certain supporting force can be provided for the pressed rack, and the external sealing structure of the refrigeration container is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of cold chain systems, in particular to a sealing device for a refrigerator that avoids sealing damage caused by extrusion. Background technique [0002] Vaccines and plasma used in medical services need to be refrigerated during storage and transportation. Generally, it is necessary to use a refrigerator to refrigerate them. However, the current refrigerators are prone to deformation after being squeezed, resulting in the sealing effect of the refrigerator seal. If it gets worse, the cold air inside will be lost quickly, which will damage the medicine inside. [0003] In order to solve the above problems, the inventor provides a refrigerator sealing device that avoids the damage of sealing caused by extrusion. The elastic cavity is subjected to the pressure of the push rod through the influence of the pressure on the frame, and the air inside the elastic cavity enters the No. 1 rack Inside, the metal conta...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sealing device for a refrigerator that avoids the damage of sealing caused by extrusion. If the external sealing structure is damaged, the air pump can be automatically started and closed, and the racks on both sides of the support frame can be close to each other. The advantage of the enhanced sealing of the internal sealing device solves the problem that the current refrigerator is easy to be squeezed. After deformation, the sealing effect of the seal of the refrigerator will become poor, and the internal cold air will be lost quickly, which will damage the internal medicines.
