[0053] The second fixing bracket 67 is provided with a U-shaped hole 671, through which a screw passes so that the second fixing bracket 67 is fixed to the intermediate fixing bracket 613. The structure of the U-shaped hole 671 is advantageous for adjusting the position of the second cylindrical through hole 672 according to actual conditions to adapt to the actual use of the first coupling shaft 57 and the second coupling shaft 58.

[0054] A decorative baffle fixing hole 332 is provided on the third baffle plate 33, and the decorative baffle is fixed in the decorative baffle fixing hole 332 by screws. In this way, when consumers bring out the dish, they will not see the industrialized dish tray 4 falling, which is suitable for civilian use.

[0055] The second stopper 32 is locked on the third stopper 33 by screws.

[0056] The working principle of the food transmission system of the insulated box as described above is as follows: the motor 7 drives the first synchronous wheel 71 to rotate, and then drives the second synchronous wheel 72 to rotate through the synchronous belt 63, and the second synchronous wheel 72 drives the second coupling shaft 58 to rotate counterclockwise, thereby driving the first chain ring 55 and the second chain ring 56 to rotate, and the first coupling shaft 57 will also be driven. Since the fixed shaft 44 of the vegetable tray 4 is vertically fixed on the first chain ring 55 and the second chain ring 56, the first chain ring 55 and the second chain ring 56 can drive the vegetable tray 4 to move upward. When the vegetable tray moves to the specified position, the dish on the vegetable tray 4 can be taken out, and the vegetable tray 4 continues to move upward, and then flips to another time, and continuously realizes the cycle.

[0057] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
