[0024] The inner wall of the slide groove 4 is slidably connected with a sleeve 6, and the rear bottom end of the sleeve 6 is fixedly connected with an anti-slip block 7. The anti-slip block 7 is connected to the sleeve 6 to prevent the sleeve 6 from escaping from the slide groove 4 of the storage block 3 when it is extended or retracted. A hole 8 is opened at the front bottom end of the sleeve 6, and the hole 8 is designed to enable the engaged parts to be retracted and extended.

[0025] A positioning rod 9 is fixedly connected to the inner left side of the sleeve 6, and a clamp 10 is rotatably connected to the outer right end of the positioning rod 9. A pull rod 11 is fixedly connected to the bottom end of the sleeve 6. Take the pull rod 11 and keep pressing the button 14 on the pull rod 11 to squeeze the spring 15 to extend and retract, driving the spring 15 to extend and retract downward to drive the clamp 10 to rotate around the positioning rod 9. A groove 12 is provided in the middle of the pull rod 11. The groove 12 is provided to allow the internal space to move. The inner wall of the pull rod 11 is slidably connected to a limiting component, which assists the sleeve 6 in extending and retracting. Compared with the above documents, the function of convenient movement is added on the basis of the original function, which is convenient for users to use.

[0026] refer to Figure 1 , Figure 2The top end of the rear side of the box shell 1 is rotatably connected with a sealing cover 22, and the component on the front side of the sealing cover 22 and the component on the front side of the box shell 1 are a buckle. When the buckle is closed, the sealing cover 22 and the box shell 1 can be tightly fitted and closed, thereby maintaining the internal sealing. The outside of the anti-slip block 7 is slidably connected to the rear side of the inner wall of the slide groove 4. Here, in order to prevent the sleeve 6 from escaping from the slide groove 4 of the storage block 3, the front end of the positioning rod 9 is engaged with the inner wall of the card hole 5, and the bottom left side of the clamping member 10 is rotatably connected to the bottom right side of the auxiliary rod 13. The auxiliary rod 13 will drive the clamping member 10 to rotate and slide again with the positioning rod 9 as the center in the hole 8 and engage with the card hole 5.

[0027] refer to Figure 3 The limiting assembly includes an auxiliary rod 13, a button 14 and a spring 15. The outer top of the auxiliary rod 13 is slidably connected to the inner wall of the groove 12, and the bottom end of the button 14 is fixedly connected to the top of the auxiliary rod 13. One end of the auxiliary rod 13 is fixedly connected to the bottom end of the button 14. The button 14 on the pull rod 11 is pressed continuously to squeeze the spring 15 to extend and retract and drive the auxiliary rod 13 downward. The other end of the auxiliary rod 13 is fixedly connected to the inner wall of the groove 12, and the outer part of the spring 15 is sleeved on the outer part of the auxiliary rod 13. The auxiliary rod 13 connects the pull rod 11 and the button 14, so that the user can hold the pull rod 11 by hand and press the button 14 to drive the spring 15 to move.

[0028] refer to Figure 4 , Figure 5 The inside of the box shell 1 is fixedly connected with an insulation layer 16, and a guide groove 17 is opened on the inner front side of the insulation layer 16. The insulation layer 16 insulates the items inside. The guide groove 17 assists the slider 18 to slide and then rotate. The inner wall of the guide groove 17 is slidably connected with the slider 18, and the rear side of the slider 18 is fixedly connected with a bottom plate 19. The outside of the bottom plate 19 is slidably connected to the inner wall of the insulation layer 16. The bottom plate 19 slides along the inner wall of the insulation layer 16 under the connection of the slider 18 and then rotates and tilts around the slider 18. The top of the bottom plate 19 is fixedly connected with a sleeve frame 20. The sleeve frame 20 and the bottom plate 19 are driven upward by pulling the handle 21. The left and right sides of the top of the sleeve frame 20 are fixedly connected with handles 21. The handles 21 are convenient for users to pull the sleeve frame 20.

[0029] Working principle: When the user places the items to be frozen in the sleeve frame 20, the entire box can be closed into a sealed state through the seal cover 22 and the buckle on the box shell 1. When the box needs to be moved, the pull rod 11 can be taken and the button 14 on the pull rod 11 can be pressed to squeeze the spring 15 to extend and retract the auxiliary rod 13 downward to drive the card 10 to rotate around the positioning rod 9 to disengage from the card hole 5, so that the card 10 will no longer be engaged with the card hole 5 after rotation, so that the user can hold the pull rod 11 to pull the card hole 5 to extend and retract to a suitable length, and then release the button 14 on the pull rod 11. The button 14 will reset under the elastic force of the spring 15. After the button 14 slides in the groove 12 and resets, it will drive the auxiliary rod 13 upward to drive the card 10 to rotate and slide in the hole 8 again around the positioning rod 9 to engage with the card hole 5, so that the user can push or pull the box shell 1 to move by pulling the pull rod 11 and the wheels 2, which is convenient for the user to move.

[0030] When the user needs to take out items from the box or needs to clean up the internal residue, the user can open the buckle of the thermal insulation box, open the sealing cover 22, and then pull the handle 21 to drive the frame 20 upward. At this time, the slider 18 fixed to the bottom plate 19 of the frame 20 slides upward stably and then tilts forward to take out all the items, and at the same time, the remaining residue and dry ice fragments inside can be cleaned up at one time.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
