[0002] The carriage is used to carry goods, but some goods need to be properly ventilated when placed to keep the goods fresh or cool down. When the goods are placed, the bottom of the goods also needs to be properly supported and ventilated.

[0003] A Chinese patent discloses a "gas convection structure in the compartment of a logistics vehicle" with the application number "CN202420071133.7". This patent mainly realizes airflow movement during vehicle driving by opening an assembly port on the middle partition of the compartment body, fixing a new airflow grille, connecting the cab and the cargo area, and having the advantages of simple structure, easy installation and operation, and outstanding gas movement effect in the compartment. However, the assembly port of the compartment of this patent cannot be actively closed or opened. When the vehicle is driving in rainy and snowy weather, rainwater can easily flow into the interior of the compartment through the open assembly port, which can easily cause water damage to the cargo, which is not conducive to the transportation of the cargo. Utility Model Content

[0011] The outer wall of the carriage is fixedly connected with a first limiting frame, and the limiting pin is located inside the first limiting frame.

[0012] As a further description of the above technical solution:

[0020] The utility model has the following beneficial effects:

[0021] Compared with the existing technology, the gas convection structure in the compartment of the logistics vehicle passes through the compartment, air inlet groove, connecting block, first baffle, movable frame, latch, first shift block, first spring, mounting plate, and limit pin. When the air inlet groove needs to be closed, the mounting plate is shifted to the left to make the limit pin move to the left, and then the limit pin no longer plays a limiting role on the first shift block. Under the action of gravity, the first baffle will rotate around the connecting block to block the air inlet groove, and at the same time will drive the movable frame, latch and first shift block to move downward, so that when air intake is not needed, external dust will not enter the interior of the compartment. When the air inlet slot needs to be opened, the first shift block is pulled upward, thereby driving the movable frame and the latch pin upward. Due to the presence of the inclined slot, the first baffle plate rotates around the connecting block, so that the first baffle plate no longer blocks the air inlet slot. At the same time, during the upward movement of the first shift block, the first shift block squeezes the oblique side of the limit pin, driving the limit pin and the mounting plate to move to the left. The first spring contracts. When the first shift block moves upward and can no longer move, the first spring rebounds and drives the mounting plate and the limit pin to reset, limiting the first shift block so that it cannot move downward. At this time, the air inlet slot is opened. Compared with the existing gas convection structure, the gas convection structure in the compartment of the logistics vehicle can choose whether to open the air inlet slot according to the situation, which is more flexible to use and is conducive to the transportation of goods.

[0022] Compared with the existing technology, the air convection structure in the compartment of the logistics vehicle is realized through the air outlet trough, the second dial block, the second baffle, the second spring, the limiting clamp, and the second spring. When the air outlet trough needs to be opened, the adjacent second dial blocks are manually moved closer together, thereby driving the second baffles closer together. The second spring contracts and simultaneously lifts the limiting clamp upward, moving the second dial blocks closer together until they can no longer move closer. The limiting clamp is then moved downward so that it limits the adjacent second dial blocks, and the air outlet trough is now opened. When the air outlet trough needs to be closed, the limiting clamp is moved upward so that it no longer limits the adjacent second dial blocks. At this time, the second spring rebounds and drives the second baffle and the second dial block to return to their original position. At this time, the air outlet trough is blocked again, ensuring that no external dust enters the compartment when ventilation is not required. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention is further described below with reference to the accompanying drawings and specific embodiments to facilitate understanding of the present invention. The methods used in the present invention are conventional methods unless otherwise specified; the raw materials and devices used are conventional commercially available products unless otherwise specified.

[0033] Reference Figure 1-7The utility model provides a gas convection structure in the compartment of a logistics vehicle: comprising a compartment 1, the outer wall of the compartment 1 is provided with an air inlet slot 2, the number of which is multiple, the inner top of the air inlet slot 2 is fixedly connected with a connecting block 3, the side wall of the connecting block 3 is movably mounted with a first baffle 4, the side wall of the first baffle 4 is provided with an inclined slot 5, the number of which is multiple. The interior of the compartment 1 is provided with a first movable slot 6, the number of which is multiple, a movable rack 7 is provided inside the first movable slot 6, the side wall of the movable rack 7 is fixedly connected with a bayonet 8, the number of which is multiple, and the bayonet 8 is located inside the inclined slot 5. The outer wall of the movable rack 7 is fixedly connected with a first shift block 9, the inner wall of the first movable slot 6 is provided with a second movable slot 10, the first shift block 9 is located inside the second movable slot 10. The outer wall of the carriage 1 is fixedly connected to a spring plate 11, the side wall of the spring plate 11 is fixedly connected to a first spring 12, the end of the first spring 12 away from the spring plate 11 is fixedly connected to a mounting plate 13, and the outer wall of the mounting plate 13 away from the first spring 12 is fixedly connected to a limiting pin 14.

[0034] When the air inlet slot 2 needs to be closed, the mounting plate 13 is pushed to the left so that the limit pin 14 moves to the left, and the limit pin 14 no longer limits the first shift block 9. Under the action of gravity, the first baffle 4 will rotate around the connecting block 3 to block the air inlet slot 2, and at the same time drive the movable frame 7, the locking pin 8 and the first shift block 9 to move downward, so that when air intake is not needed, the interior of the carriage 1 will not be exposed to external dust. When the air inlet slot 2 needs to be opened, the first shift block 9 is pulled upward, thereby driving the movable frame 7 and the latch 8 to move upward. Due to the existence of the inclined slot 5, the first baffle 4 will rotate around the connecting block 3, so that the first baffle 4 no longer blocks the air inlet slot 2. At the same time, during the upward movement of the first shift block 9, the first shift block 9 will squeeze the oblique edge of the limit pin 14, driving the limit pin 14 and the mounting plate 13 to move to the left, and the first spring 12 contracts. When the first shift block 9 moves up to where it can no longer move, the first spring 12 rebounds and drives the mounting plate 13 and the limit pin 14 to reset, limiting the first shift block 9 so that the first shift block 9 cannot move downward. At this time, the air inlet slot 2 is opened.

[0035] The outer wall of the carriage 1 is fixedly connected to a first limit frame 15, and the limit pin 14 is located inside the first limit frame 15. The first limit frame 15 can limit the movement direction of the limit pin 14, and the mounting plate 13 and the first limit frame 15 can cooperate to limit the movement distance of the limit pin 14.

[0036] The outer wall of the carriage 1 is provided with two air outlet slots 16, and the inner wall of the air outlet slot 16 is provided with a spring slot 17. A second spring 18 is fixedly connected to the inner wall of the spring slot 17, and a second baffle 19 is fixedly connected to one end of the second spring 18. A third movable slot 21 is provided on the inner wall of the spring slot 17, and a second shift block 20 is fixedly connected to the outer wall of the second baffle 19. The second shift block 20 is located inside the third movable slot 21. A second limit frame 22 is fixedly connected to the outer wall of the carriage 1, and a limit clamp 23 is movably installed inside the second limit frame 22. The upper surface of the limit clamp 23 is fixedly connected to the limit block 24.

[0037] When the air outlet slot 16 needs to be opened, the adjacent second dial blocks 20 are manually moved closer together, thereby driving the second baffle 19 closer together, the second spring 18 contracts, and at the same time the limiting clip 23 is lifted upward, and the second dial blocks 20 are moved closer together until they can no longer move closer together. The limiting clip 23 is then moved downward so that the limiting clip 23 limits the adjacent second dial blocks 20, and the air outlet slot 16 is now opened. When the air outlet slot 16 needs to be closed, the limiting clip 23 is moved upward so that the limiting clip 23 no longer limits the adjacent second dial blocks 20. At this time, the second spring 18 rebounds and drives the second baffle 19 and the second dial block 20 to return to their original position. At this time, the air outlet slot 16 is blocked again, ensuring that no external dust enters the vehicle compartment when ventilation is not required.

[0038] Working principle:

[0039] When the air inlet slot 2 needs to be closed, the mounting plate 13 is pushed to the left so that the limit pin 14 moves to the left, and the limit pin 14 no longer limits the first shift block 9. Under the action of gravity, the first baffle 4 will rotate around the connecting block 3 to block the air inlet slot 2, and at the same time drive the movable frame 7, the locking pin 8 and the first shift block 9 to move downward, so that the interior of the compartment 1 will not enter the outside dust when air intake is not needed. When the air inlet slot 2 needs to be opened, the first shift block 9 is pulled upward, thereby driving the movable frame 7 and the latch 8 to move upward. Due to the existence of the inclined slot 5, the first baffle 4 will rotate around the connecting block 3, so that the first baffle 4 no longer blocks the air inlet slot 2. At the same time, during the upward movement of the first shift block 9, the first shift block 9 will squeeze the oblique edge of the limit pin 14, driving the limit pin 14 and the mounting plate 13 to move to the left, and the first spring 12 contracts. When the first shift block 9 moves up to where it can no longer move, the first spring 12 rebounds and drives the mounting plate 13 and the limit pin 14 to reset, limiting the first shift block 9 so that the first shift block 9 cannot move downward. At this time, the air inlet slot 2 is opened.

[0040] When the air outlet slot 16 needs to be opened, the adjacent second dial blocks 20 are manually moved closer together, thereby driving the second baffle 19 closer together, the second spring 18 contracts, and at the same time the limiting clip 23 is lifted upward, and the second dial blocks 20 are moved closer together until they can no longer move closer together. The limiting clip 23 is then moved downward so that the limiting clip 23 limits the adjacent second dial blocks 20, and the air outlet slot 16 is now opened. When the air outlet slot 16 needs to be closed, the limiting clip 23 is moved upward so that the limiting clip 23 no longer limits the adjacent second dial blocks 20. At this time, the second spring 18 rebounds and drives the second baffle 19 and the second dial block 20 to return to their original position. At this time, the air outlet slot 16 is blocked again, ensuring that no external dust enters the vehicle compartment when ventilation is not required.
