Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, and in particular provides a logistics transportation system which is convenient for loading and unloading. Background Art

[0002] Cargo transportation by vehicle is one of the main modes of modern transportation. When a logistics transport vehicle arrives at a designated location, it is usually necessary to load and unload the goods. Among various types of cargo transport vehicles, large and medium-sized logistics transport vehicles generally use larger loading and unloading machinery such as electric forklifts to load and unload goods due to the large and concentrated cargo volume; while small and medium-sized logistics transport vehicles have a small cargo volume and a small cargo compartment space, and cannot use loading machinery to load and unload goods, so they can only rely on manual loading and unloading. With the sharp increase in the amount of cargo, it is necessary to shuttle back and forth throughout the entire compartment to move the goods in or out of the compartment one by one, which is time-consuming and labor-intensive, and has low efficiency.

[0003] On the other hand, when loading and unloading small and medium-sized logistics transport vehicles, it is often necessary to carry large goods or heavy items onto or unload the vehicle, which is very unfriendly to thin people or girls. They can only borrow additional auxiliary tools or ask others for help.

At this time, the state of the auxiliary loading and unloading unit 2 is as shown in FIG. Figure 5 As shown; the first crossbar 313 at the intersection of the second side 322 and the fourth side 324 is used as the rotation axis to rotate the atomic box unit 3 clockwise, so that the first crossbar 313 at the intersection of the fourth side 324 and the fifth side 325 is inserted into the U-shaped groove of the positioning block 222 along the inclined surface of the lock hook 223, and the lock hook 223 is pressed against the first crossbar 313 under the action of the lock hook elastic member 224, so that the combination of the atomic box unit 3 and the auxiliary loading and unloading unit 2 is completed. At this time, the force storage elastic member 24 is in the maximum force storage state, and the atomic box unit 3 and the auxiliary loading and unloading unit 2 are in a vertical state.

[0106] like Figure 3 As shown, the user rotates with the rotating shaft 216 as the central axis, and with the help of the force storage elastic member 24, the user successively holds the first cross bar 313 at the intersection of the third side surface 323 and the fifth side surface 325, the second cross bar 314 in the middle of the third side surface 323, the flip handle 315, and the second cross bar 314 in the middle of the second side surface 322 to flip the atomic box unit 3 to the upper end of the chassis frame 11, and the atomic box unit 3 descends along the guide plate 228 to contact the flip body 221; at this time, the state of the auxiliary loading and unloading unit 2 is as shown in FIG. Fig.16 As shown, continue to hold the second cross bar 314 in the middle of the second side surface 322 and push it forward along the guide rail 212 until the end, as shown in FIG. Figure 4 As shown; at this time, the limit shaft 215 is inserted into the limit buckle groove 219, and then the unlocking handle 226 is turned counterclockwise to clamp it with the rolling shaft 232, thereby completing the locking; at this time, the atomic box unit 3 and the auxiliary loading and unloading unit 2 are in a horizontal state, and the state of the auxiliary loading and unloading unit 2 is as shown Fig.17 As shown, loading is now completed.

[0107] The chassis unit 1 carries one or more atomic box units 3 to the next station and is also unloaded manually; the unloading process is the reverse operation of the loading process and will not be elaborated here; it should be noted that before pulling the atomic box unit 3, the user needs to turn the unlocking handle 226 clockwise to complete the unlocking of the auxiliary loading and unloading unit 2 and the atomic box unit 3 as a whole before unloading; when the atomic box unit 3 and the auxiliary loading and unloading unit 2 are in a vertical state, it is necessary to turn the lock hook 223 again to complete the unlocking of the atomic box unit 3, and then step on the foot pedal 34 to release the atomic box unit 3. At this time, the atomic box unit 3 is removed to complete the unloading, and the auxiliary loading and unloading unit 2 returns to the initial position under the action of the force storage elastic member 24, and waits for the next loading in this state.

[0108] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
