When the limiting block 313 needs to be controlled to be far away from the pushing block 311, the pushing column 71 is pressed, and at this time, the pushing column 71 pushes the sliding column 315 into the sliding groove 314 through the abutting block 711, so that the limiting block 313 is far away from the pushing block 311.

The implementation principle of the heat preservation meeting meal conveying equipment is as follows:

when the meeting meal is conveyed, firstly, the dinner plate is placed on the top of the supporting plate 2, then the driving wheel 32 is driven to rotate positively in the advancing process of the vehicle body 1, at the moment, the driving belt 63 drives the driving shaft 31 to rotate positively, and the driving block 311 is abutted to the fixing block 621 to drive the mounting column 6 to rotate positively, so that the connecting column 21 slides downwards. The connecting column 21 drives the supporting plate 2 to slide downwards when sliding downwards, so that the dinner plate enters the accommodating groove 12, and the possibility of sliding the dinner plate when the vehicle body 1 advances is reduced. Meanwhile, the support plate 2 drives the overturning column 4 to overturn when moving downwards, so that the heat preservation cloth 41 covers the accommodating groove 12 to preserve heat of the conference meal. When the vehicle body 1 moves to the destination, the pushing post 71 is pressed so that the limiting block 313 is far away from the pushing block 311, and at this time, the driving spring 13 pushes the supporting plate 2 to slide upwards, so that the overturning post 4 overturns in the opposite direction to open the accommodating groove 12, and when the supporting plate 2 moves to the top of the supporting plate and the top of the vehicle body 1 are in the same plane, the dinner plate can be taken out. The whole process is simple, restrict the dinner plate motion through holding tank 12 cell wall, reduce the food on the dinner plate and appear spilling, leaking the possibility for the travel speed of automobile body 1 can increase, is favorable to promoting the timeliness of dining.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
