[0015] Preferably, the storage cart comprises a sub-trolley frame and storage trays longitudinally spaced apart from each other on the sub-trolley frame.

[0016] With the above solution, the advantage of arranging the storage trays at intervals in the longitudinal direction is that the space utilization rate is improved.

[0017] Preferably, the storage tray is pull-out and arranged on the sub-trolley frame, and a plurality of groups of support and guide assemblies are longitudinally arranged on the sub-trolley frame, and the support and guide assemblies include guide seats fixed and "L"-shaped on both sides of the sub-trolley frame, and both sides of the opening of the storage tray are folded outward to have overlapping folded edges that overlap the upper ends of the horizontal sections of the guide seats.

[0018] By adopting the above scheme, the storage tray is overlapped on the guide seat by the overlapping folded edges on both sides of the upper end, so that the overlapping folded edges can be guided and moved on the guide seat, thereby realizing the guided movement of the storage tray on the vehicle frame.

[0019] Preferably, a limiting rod is provided at one end of the sub-trolley frame away from the storage tray, and the limiting rod has two ends fixedly connected to the upper and lower ends of the sub-trolley frame respectively.

[0020] With the above solution, in order to facilitate the storage trolley to enter the quick-freezing chamber smoothly, the connecting plate is generally horizontal after being overlapped at the bottom of the quick-freezing chamber. However, if there is a tendency to tilt downward toward the inside of the quick-freezing chamber, the limit rod can prevent the storage tray from moving forward.

[0021] Preferably, rolling bodies for reducing friction with the inner wall of the quick-freezing chamber of the quick-freezing cabinet are arranged at intervals on both sides of the frame of the sub-trolley along its moving direction.

[0022] Preferably, the rolling element is a bull's eye bearing.

[0023] By adopting the above solution, after the storage trolley enters the quick-freezing chamber, the bull's eye bearings on both sides thereof roll in cooperation with the inner wall of the quick-freezing chamber, so that the entry and exit is convenient, labor-saving and less worn.

[0024] Preferably, a handle is fixed on the frame of the sub-trolley at the end where the storage tray is placed so as to facilitate pushing and pulling.

[0025] With the above solution, the handle makes it convenient for operators to push and pull the storage cart.

[0026] The utility model has remarkable technical effects due to the adoption of the above technical scheme: the conveying device is composed of a storage trolley for placing in the quick-freezing cabinet and a mobile mother trolley for quickly transporting the storage trolley into the quick-freezing cabinet, the mobile mother trolley is provided with a blocking component and a connecting plate, the blocking component limits the detachment of the storage trolley from the mobile mother trolley during the transportation of the mobile mother trolley, and allows the storage trolley to detach from the mobile mother trolley after the mobile mother trolley moves to the target point, and the connecting plate connects the mobile mother trolley with the quick-freezing chamber of the quick-freezing cabinet, so that the storage trolley can directly enter the quick-freezing cabinet, and the operation is very convenient and labor-saving.
