[0028] When installing the small refrigeration box 3 in the outer protection box 2, first insert the docking base 31 at the lower end of the small refrigeration box 3 into the shock-absorbing seat 201, and then insert the support block 32 downward into the support groove at the bottom of the inner cavity of the outer protection box 2, and at the same time, insert the docking plug block 204 at the bottom of the outer protection box 2 into the docking slot 35 at the lower end of the docking base 31; When the docking plug block 204 contacts the slope at the lower end of the locking block 43, the docking base 31 drives the locking mechanism to move downward. At this time, the docking plug block 204 generates an extrusion thrust on the locking block 43, causing the locking block 43 to shrink into the convex movable groove 34. At the same time, the convex movable seat 4 slides along the convex movable groove 34, and the convex movable seat 4 squeezes the first elastic sheet 42. When the docking block 204 is fully inserted into the docking slot 35, the convex movable seat 4 is pushed to reset under the action of the elastic force of the first elastic sheet 42, and the convex movable seat 4 drives the locking block 43 to be inserted into the slot of the docking block 204, thereby locking the docking block 204. The docking block 204 and the docking base 31 are relatively fixed through the provided locking mechanism, thereby completing the installation and fixation of the small refrigeration box 3, and at the same time, the refrigeration box electrical connector 33 at the lower end of the small refrigeration box 3 is plugged into the power plug 202.

[0030] When the refrigeration box electrical connector 33 is plugged into the power plug 202, the T-shaped sealing plates 5 of the two sealing mechanisms symmetrically abut against the side of the power plug 202. At this time, a portion of the T-shaped sealing plate 5 shrinks into the T-shaped shrink groove 41, and the T-shaped sealing plate 5 squeezes the second elastic sheet 51. When the refrigeration box electrical connector 33 is not plugged into the power plug 202, that is, the small refrigeration box 3 is removed from the outer protective box 2, the elastic force of the second elastic sheet 51 causes the ends of the T-shaped sealing plates 5 of the two sealing mechanisms to dock with each other, and at the same time, the upper end of the T-shaped sealing plate 5 contacts the lower end of the refrigeration box electrical connector 33, thereby sealing the lower end of the refrigeration box electrical connector 33 to prevent external dust, debris, water stains, etc. from entering the refrigeration box electrical connector 33.

[0031] See also Figure 7 , Fig.11 and Fig.12 The unlocking mechanism includes a bidirectional transmission screw 6 installed in the bottom of the outer protection box 2. The bidirectional transmission screw 6 is a round rod with left-handed threads and right-handed threads symmetrically opened at both ends. The middle position of the round rod is a smooth surface. The smooth position of the bidirectional transmission screw 6 is rotatably connected to the outer protection box 2. The two ends of the bidirectional transmission screw 6 with threads are respectively arranged in two limit grooves 203. The two ends of the bidirectional transmission screw 6 are symmetrically fixedly connected with round shafts. The bidirectional transmission screw 6 is rotatably connected to the outer protection box 2 through the round shaft. A notch is provided at the lower end of one side of the outer protective box 2, and the circular shaft at one end of the bidirectional transmission screw 6 passes through the outer protective box 2, extends into the notch and is fixedly connected to the knob 61. The two ends of the bidirectional transmission screw 6 are symmetrically sleeved with threaded sleeves 62, and the sides of the threaded sleeves 62 are fixedly connected with transmission plates 63.

[0032] The threaded sleeve 62 and the transmission plate 63 are both slidably connected to the limiting groove 203 , and the threaded sleeve 62 is threadedly connected to the bidirectional transmission screw 6 .

[0033] Initially, the two threaded sleeves 62 are respectively located at the ends of the two limit grooves 203 close to each other, and at this time, the transmission plate 63 will not affect the left and right movement of the connecting plate 44; When the small refrigeration box 3 needs to be disassembled from the outer protection box 2, the knob 61 is turned to drive the two-way transmission screw 6 to rotate synchronously. When the two-way transmission screw 6 rotates, the two threaded sleeves 62 thereon are driven to move away from each other, and the threaded sleeve 62 drives the transmission plate 63 to slide along the limit groove 203. At the same time, the transmission plate 63 pushes the connecting plate 44 to slide along the guide groove. The connecting plate 44 drives the convex movable seat 4 to slide along the convex movable groove 34. At the same time, the convex movable seat 4 drives the locking block 43 and the T-shaped sealing plate 5 to slide into the convex movable groove 34, so that the locking block 43 is moved out of the groove on the side of the docking block 204, and at the same time, the T-shaped sealing plate 5 is kept away from the power plug 202, and at this time, the T-shaped sealing plate 5 is not in contact with the lower end of the refrigeration box electrical connector 33; At this time, the small refrigeration box 3 can be pulled upward along the inner cavity of the outer protection box 2, so as to complete the disassembly of the small refrigeration box 3. The locking mechanism can be used to conveniently install and disassemble the small refrigeration box 3, which is convenient for the delivery staff to operate; especially when the takeaway vehicle cannot be ridden to the downstairs or door of the customer, some items and food need to be refrigerated. At this time, the small refrigeration box 3 can be disassembled. After the power is cut off, the interior of the small refrigeration box 3 will still maintain a low temperature for a period of time. The small refrigeration box 3 can continue to refrigerate the items and food until they are delivered to the customer's home and then taken out, thereby ensuring the quality of the items and food.

[0034] Working principle: By installing a small refrigeration box 3 on the two-wheeled delivery vehicle 1, some cream cakes, ice cream, fresh food, fruits, etc. can be transported in low temperature and refrigerated to ensure their quality. The small refrigeration box 3 can cool down in a short time; the small refrigeration box 3 is installed in the outer protection box 2, and the small refrigeration box 3 is protected by the outer protection box 2 to prevent the small refrigeration box 3 from being damaged by external collisions. A plurality of hooks 23 are installed on the side of the outer protective box 2, so that the delivery personnel can deliver more orders; when some take-outs with soup that do not require refrigeration need to be placed, the flip door 22 is flipped downward by 90 degrees to open it, so that the hooks 23 on the side of the flip door 22 abut against the rear side of the outer protective box 2, and the positioning column 24 is fixedly engaged with the positioning hole on the hook 23; The takeaway is hung on the hook 23 on the rear side of the outer protective box 2, and the lower end of the takeaway box is stuck in the lunch box limit seat 25, so as to support the takeaway box and prevent the takeaway box from tilting during the delivery process and causing the soup to spill.

[0035] The front side of the outer protection box 2 and the front side of the box cover 21 can be connected by a lock, thereby achieving a certain anti-theft effect and preventing the contents in the small refrigeration box 3 from being stolen.

[0036] When the takeaway vehicle cannot ride to the customer's downstairs or door, and some items and food need to be continuously refrigerated and delivered, the small refrigeration box 3 can be removed from the outer protection box 2 for delivery, thereby ensuring the quality of the items in the small refrigeration box 3; When it is necessary to disassemble the small refrigeration box 3, first flip and open the box cover 21 at the upper end of the outer protection box 2, and then drive the two-way transmission screw 6 to rotate by turning the knob 61, so that the two threaded sleeves 62 on the two-way transmission screw 6 move away from each other, and the threaded sleeve 62 drives the transmission plate 63 to slide along the limit groove 203, and at the same time, the transmission plate 63 pushes the connecting plate 44 to slide along the guide groove, and the connecting plate 44 drives the convex movable seat 4 to slide along the convex movable groove 34, and at the same time, the convex movable seat 4 drives the locking block 43 to slide into the convex movable groove 34, so that the locking block 43 is moved out of the groove on the side of the docking block 204, and at the same time, the T-shaped sealing plate 5 is away from the power plug 202; at this time, the small refrigeration box 3 can be pulled upward along the inner cavity of the outer protection box 2, thereby completing the disassembly of the small refrigeration box 3; When the small refrigeration box 3 is taken out from the outer protection box 2, the small refrigeration box 3 drives the docking base 31 to move upward, and the docking base 31 drives the support block 32 to move out of the support groove at the bottom of the outer protection box 2. At the same time, the docking base 31 drives the connecting plate 44 to separate from the bottom of the outer protection box 2. At this time, the convex movable seat 4 is reset under the action of the elastic force of the first elastic sheet 42, and the convex movable seat 4 drives the locking block 43 to extend into the docking slot 35.
