DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The invention of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various inventions with various modifications suitable for specific purposes.

[0021] See also Figures 1 to 5In this embodiment, a portable refrigerator is provided, including a shell 1 and a refrigerator body 2. A bottom column 11 is installed near the four corners of the bottom of the shell 1, and a moving wheel 12 is installed at the bottom of the bottom column 11. A placement groove 13 is opened at the bottom of the inner bottom of the shell 1 near the four corners, and an outer wheel 14 is installed at the bottom of the placement groove 13. A connecting rod is installed on the upper end surface of the outer wheel 14, and the refrigerator body 2 is installed on the upper end surface of the connecting rod. A cover plate 15 is installed on the upper end surface of the shell 1 through a pin shaft, and a handle 16 is installed on the rear end surface of the shell 1. When working, the refrigerator body 2 is placed in the shell 1, the cover plate 15 seals the shell 1, and the shell 1 is pushed to move by the handle 16, so that the refrigerator body 2 is carried, and at the same time, the refrigerator body 2 is effectively prevented from being bumped during the movement to cause damage to the internal structure. The placement groove 13 plays a positioning role for the refrigerator body 2, so as to prevent the refrigerator body 2 from shaking due to road bumps during the movement of the shell 1.

[0022] A square groove is provided at the middle end of the bottom of the shell 1, a top plate 17 is arranged in the square groove, an adjusting cylinder 18 is arranged at the bottom of the top plate 17, and the adjusting cylinder 18 is installed at the bottom of the shell 1. During operation, when the refrigerator body 2 is moved, the adjusting cylinder 18 is started to drive the refrigerator body 2 to move up and separate it from the placement groove 13, so that the refrigerator body 2 can be taken out easily without multiple people lifting the refrigerator body 2, and the strength requirement is small.

[0023] The front end face of the shell 1 is installed with a front plate, and the front end face of the front plate is rotatably installed with a guide plate 19 through a pin shaft. When working, the guide plate 19 is rotated and one end of it is placed against the ground to make it tilted. The refrigerator body 2 slides to the ground through the guide plate 19, which improves the convenience of using the device.

[0024] The left and right side walls of the shell 1 are symmetrically installed with side frames 21, and the front end faces of the side frames 21 are installed with sliding plates 22 by means of sliding cooperation. During operation, when the shell 1 moves, the guide plate 19 is flipped upward, and the sliding plate 22 is moved inward, so that the guide plate 19 is limited and fixed, and the guide plate 19 limits and fixes the cover plate 15, so as to prevent the cover plate 15 from being accidentally opened.

[0025] The front end surface of the guide plate 19 is symmetrically mounted with a fixing seat 23, and the fixing seat 23 and the sliding plate 22 are clamped together by a first clamping head 24. During operation, the sliding plate 22 is clamped together with the fixing seat 23 when it moves inward, thereby preventing the sliding plate 22 from sliding when the housing 1 moves, causing the guide plate 19 to rotate and causing a safety accident.

[0026] A sponge pad 25 is installed at the bottom of the cover plate 15, and a refrigerator body 2 is arranged at the bottom of the sponge pad 25. During operation, when the shell 1 moves, road bumps may cause the refrigerator body 2 to shake up and down, and the sponge pad 25 plays a shock-absorbing and protective role on the top of the refrigerator body 2.

[0027] During specific operation, the refrigerator body 2 is placed in the outer shell 1, the cover plate 15 seals the outer shell 1, and the outer shell 1 is pushed and moved by the handle 16, so that the refrigerator body 2 is carried, and at the same time, the refrigerator body 2 is effectively prevented from being bumped during the movement to cause damage to the internal structure. The placement groove 13 plays a positioning role for the refrigerator body 2 to prevent the refrigerator body 2 from shaking due to road bumps during the movement of the outer shell 1.
