[0002] A refrigerator is a machine that transfers heat from a cooled object with a lower temperature to the ambient medium to obtain cooling. The heat transferred from the object with a lower temperature is usually called cooling. The working fluid involved in the thermal process changes in the refrigerator is called refrigerant. The refrigeration temperature range is usually above 120K, and below 120K belongs to the deep cryogenic technology range. Refrigerator is widely used in industrial and agricultural production and daily life.

The utility model is based on the universal wheels and pull rods of portable refrigerators on the existing market, and two shoulder straps are symmetrically connected to the rear end surface of the refrigerator, which is beneficial for the user to carry the refrigerator on his back through the setting of two shoulder straps when it is not possible to walk on uneven ground with universal wheels, and it is convenient to carry it without the need to carry it by manual grasping and lifting, which reduces the user's physical consumption.

[0004] Although the above scheme has the advantages as mentioned above, the disadvantage of the above scheme is that, when in use, the cold air cannot be blown more evenly. Since the refrigerator is small in size and the cold air fan is kept in a fixed position, the blowing direction of the cold air is limited, and the cold air generated by the refrigerator cannot be released evenly, which reduces the cooling effect of the refrigerator.

After moving for a long time, the internal electronic components of the refrigerator will become loose and damaged. The vibration generated by the refrigerator cannot be buffered and shock-absorbed during movement, which reduces the service life of the refrigerator. Utility Model Content

[0032] In this embodiment, the refrigerator body 1 is turned on by the button 101, and the refrigeration temperature of the refrigerator body 1 is adjusted by the adjustment knob 102. At this time, the interior of the refrigerator body 1 begins to refrigerate, and the cold air generated by the refrigeration is blown out through the blowing plate 106. In order to make the cold air blow more evenly, the staff turns on the external power supply of the motor 2 118, starts the motor 2 118, and the output end of the motor 2 118 starts to drive one of the cylinders 117 to rotate forward, and one of the cylinders 117 rotates by driving 119 to make the other cylinder 117 rotate forward, and the other cylinder 117 rotates forward while driving the rotating plate 109 to rotate, and the force generated by the rotation of the rotating plate 109 drives the swing rod 1 110 to rotate in a circular motion.

When moving, the vibration generated by the refrigerator can be buffered and shock-absorbed, thereby increasing the service life of the refrigerator.

[0035] Working principle: When in use, the staff first turns on the refrigerator body 1 through the button 101, and uses the adjustment knob 102 to adjust the refrigeration temperature of the refrigerator body 1. At this time, the interior of the refrigerator body 1 begins to refrigerate, and the cold air generated by the refrigeration is blown out through the blowing plate 106. In order to make the cold air blow more evenly, the staff turns on the external power supply of the motor 118 and starts the motor 118. The output end of the motor 118 starts to drive one of the cylinders 117 to rotate forward. One of the cylinders 117 rotates by driving 119 to make the other cylinder 117 rotate forward. The other cylinder 117 rotates forward while driving the rotating plate 109 to rotate. The force generated by the rotation of the rotating plate 109 drives the swing rod 110 to move in a circular shape. The swing rod 111 starts to move with the swing rod 110 and drives the slider 112 to move up and down in the hollow plate 107.

The fan 116 starts to rotate and generates wind. Through the overall up and down circular reciprocating motion of the fan 116, the cold air blown out by the blowing plate 106 is evenly blown to all places, so that the cold air is blown more evenly, avoiding the limited blowing direction of the cold air, and can evenly release the cold air generated by the refrigerator body 1, thereby improving the refrigeration effect of the refrigerator. In order to facilitate the movement of the refrigerator body 1, the staff pulls the pull rod 103 as needed, and the pull rod 103 is used to The refrigerator body 1 is pulled to move as a whole. When encountering an uneven road surface, the universal wheel 202 begins to bump and vibrate, and the force generated by the vibration is transmitted to the damper 2 through the universal wheel 202, and the spring 201 and the damper 2 are used to gradually disperse the force generated by the vibration, so as to facilitate movement. When encountering an uneven road surface, the bumps can be reduced, and the damage to the internal electronic components of the refrigerator body 1 caused by long-term bumps can be avoided. When moving, the vibration generated by the refrigerator can be buffered and shock-absorbed, thereby increasing the service life of the refrigerator.
