Description

Technical Field

[0001] The utility model relates to the technical field of cargo transportation, in particular to a cart for convenient loading and unloading of cargo. Background Art

[0002] In the process of preparing for cargo transportation, the finished goods need to be transported to the truck. The prior art requires manual handling of the goods, which is not convenient enough. For example, a trolley for easy loading and unloading is recorded in the patent with patent announcement number CN 220220784 U, which includes a load-bearing bottom plate and a storage box. The bottom of the load-bearing bottom plate is fixedly installed with brake wheels near the edges of the four corners. The handle can drive the load-bearing bottom plate on the top of the brake wheel to move, so as to transport the logistics in the storage box. When reaching the edge of the logistics transport truck, the No. 1 brake stepper motor can be started to drive the storage box to the storage height of the truck. The opening and closing door can facilitate the personnel on the truck to load and unload materials directly at the storage box. The trolley structure described in the prior art only requires one person to complete the loading and unloading work, which effectively improves the convenience of material loading and unloading, so that the unloading plate can slide on the inner wall of the storage box so that the logistics in the storage box can be pushed out, thereby realizing the rapid unloading of the fast trolley, but workers are still required to carry the goods to achieve the problem of loading and unloading, which consumes a lot of time and energy.

[0003] Based on this, a trolley is now provided for convenient loading and unloading of goods, which can eliminate the disadvantage of requiring manual labor to carry the goods. Utility Model Content

[0026] In one embodiment, Figure 1 and Figure 3As shown, the adjustment mechanism 6 includes a support leg 61 rotatably connected to the lower surface of the support frame 3, and a rubber anti-collision block 11 is arranged on the side of the support leg 61 away from the fixing mechanism 643 to prevent the support leg 61 from being deformed and causing damage to the cart during the collision between the support leg 61 and the truck when the cart is sent to the truck. A second roller 62 is arranged at the end of the support leg 61 away from the support frame 3, and a stabilizing rod 63 is arranged between the support legs 61 at the lower end of the same support frame 3. An adjustment component 64 is arranged at the midline position of the support leg 61, and the adjustment component 64 includes a first folding rod 641 rotatably connected to the middle position of the support leg 61, and the other end of the first folding rod 641 is rotatably connected to the second folding rod 642, the first folding rod 641 and the second folding rod 642 are concave, and the surface of the second folding rod 642 is rotatably connected to the fixing mechanism 643, and the fixing mechanism 643 includes a first folding rod 641 rotatably connected to the first folding rod 641. The control rod 6431 on the surface of the second folding rod 642, the other end of the control rod 6431 is fixedly connected with a locking rod 6432, and a slot 6433 is provided on the surface of the first folding rod 641, and the locking rod 6432 is engaged in the slot 6433. When the goods need to be transported to the truck, the truck is pushed to move, and the second roller 62 contacts the ground and rolls. At this time, the locking rod 6432 is engaged in the slot 6433. The first folding rod 641 and the second folding rod 642 are located in the same straight line, playing a supporting role until the supporting leg 61 collides with the truck, the first folding rod 641 and the second folding rod 642 are folded, the locking rod 6432 falls off from the slot 6433, and the supporting leg 61 is folded at the same time. At this time, the second roller 62 contacts the bottom end of the truck compartment. When the goods are taken out, the cart is pulled to restore the supporting leg 61 and the support rod 2, thereby achieving the goal of portable loading and unloading of goods.

[0027] Example 2

[0028] The difference from Example 1 is that Figure 4As shown, the size control mechanism 4 includes a pair of control frames 41 fixedly connected to one end of the connecting vertical rod 8, a plurality of adjustment holes 42 are opened at the upper end of the control frame 41, a control telescopic rod 43 is arranged between the control frames 41, a locking assembly 44 is arranged on the surface of the control telescopic rod 43, and the locking assembly 44 includes a limiting groove 441 opened on one side of the control telescopic rod 43, a return spring 442 is arranged inside the limiting groove 441, the other end of the return spring 442 is fixedly connected to the limiting block 443, and a limiting block 44 is arranged on the surface of the limiting block 443 away from the return spring 442. 4. The limiting block 444 is engaged in the adjusting hole 42. When a large amount of goods needs to be transported and the truck is not big enough, the telescopic rod 43 can be pulled to extend and retract. The first telescopic rod 5 and the second telescopic rod 10 are extended and retracted together to adjust the size of the truck. The truck is fixed by the locking assembly 44. When the telescopic rod 43 is pulled to the desired position, the limiting block 444 is engaged in the corresponding limiting hole. When the telescopic rod 43 needs to be adjusted, the limiting block 444 is pressed to make the limiting block 444 slide out of the limiting hole. The reset spring 442 is compressed to release the fixation of the telescopic rod 43.

[0029] The above embodiment discloses a trolley for convenient loading and unloading of goods, wherein, when a large amount of goods needs to be transported and the size of the truck is insufficient, the telescopic rod 43 can be pulled to extend and retract, and the first telescopic rod 5 and the second telescopic rod 10 can be extended and retracted together to adjust the size of the truck, and fixed by the locking component 44. When the telescopic rod 43 is pulled to the desired position, the limiting block 444 is engaged in the corresponding limiting hole. When the telescopic rod 43 needs to be adjusted, the limiting block 444 is pressed to make the limiting block 444 slide out of the limiting hole, and the reset spring 442 is compressed to release the fixation of the telescopic rod 43. When the goods need to be transported to the truck, the truck is pushed to move. At this time, the second roller 62 contacts the ground and rolls. At this time, the locking rod 6432 is engaged in the slot 6433. The first folding rod 641 and the second folding rod 642 are located in the same straight line, playing a supporting role until the support leg 61 collides with the truck. The first folding rod 641 and the second folding rod 642 are folded, and the locking rod 6432 falls off from the slot 6433. The support leg 61 is folded at the same time. At this time, the second roller 62 contacts the bottom end of the truck compartment. When taking out the goods, pull the cart to restore the support leg 61 and the support rod 2, thereby achieving the goal of portable loading and unloading of goods, avoiding manual handling of goods, and making it easier and more convenient.

[0030] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
