[0002] A trolley is a hand-pushed or pulled tool used for short-distance transport of goods. It is widely used in warehouses, factories, supermarkets, homes, and other settings. It has a strong load-bearing capacity and can meet the transport needs of different occasions. It can also be divided into unicycles, two-wheeled trolleys, three-wheeled trolleys, and four-wheeled trolleys based on the number of wheels.

[0003] Existing pallet trolleys typically consist of a push rod, wheels, and a loading platform. When moving items, simply place them on the loading platform and push the push rod to move the platform and items. Currently, items are usually moved manually by workers when they are moved to the loading platform. However, if the items are heavy, multiple workers are needed to move them, which greatly reduces the efficiency of the process. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a convenient heavy-duty transport trolley, which effectively solves the problem that the convenient heavy-duty transport trolley is inconvenient to transport heavy objects during use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a convenient heavy object transport trolley, including a trolley body for transporting heavy objects, wherein a support structure is provided on one side of the trolley body to facilitate the sliding of items to the top of the trolley body;

[0006] The support structure includes a support plate, a rotating assembly, multiple support wheels, and multiple support members. One end of the support plate has a mounting groove for mounting the rotating assembly, and both ends of the rotating assembly are rotatably connected to the inner sides of the mounting groove. The top of the support plate has multiple sliding grooves for the support wheels to roll, and both sides of the sliding grooves have grooves for mounting the support members. The bottoms of the multiple support members are fixedly connected to the bottom ends of the multiple grooves. Both sides of the support wheels have connecting posts, and the end of the connecting post away from the support wheel has an auxiliary wheel, which is rotatably connected to the connecting post. The top of the support member has a limiting groove for the auxiliary wheel to slide. The end of the support plate away from the mounting groove has a connecting plate, and the top of the connecting plate is inclined.

[0007] Preferably, the support member includes a support rod and a plurality of springs. The support rod is located inside the groove, and the top of the support rod is provided with a limiting groove for the auxiliary wheel to slide. One end of each of the plurality of springs is fixedly connected to the bottom of the support rod, and the end of each of the plurality of springs away from the support rod is fixedly connected to the bottom end inside the groove. The outer side of the auxiliary wheel is in contact with the inner side of the limiting groove.

[0008] Preferably, the surface of the support plate is provided with multiple anti-slip strips.

[0009] Preferably, the rotating assembly includes a fixed column, a connecting rod, and a sleeve. The two ends of the fixed column are fixedly connected to the two sides inside the mounting groove, and the sleeve is sleeved on the outside of the fixed column. The sleeve and the fixed column are rotatably connected. One side of the connecting rod is fixedly connected to the outside of the sleeve, and the side of the connecting rod away from the sleeve is fixedly connected to one side of the trolley body.

[0010] Preferably, both sides of the support plate are provided with a locking structure. The locking structure includes a limiting member, a fixing block and a connecting block. One side of the fixing block is fixedly connected to one side of the support plate, the bottom of the connecting block is fixedly connected to the top of the fixing block, and the top of the connecting block is provided with a locking block. The top of the trolley body is provided with multiple slots that match the shape of the locking block, and one side of the slot is provided with a fixing groove for installing the limiting member.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When moving heavy objects, place one end of the object on top of the connecting plate, allowing it to slide along the inclined surface of the connecting plate towards the top of the support plate. Once the object reaches the top of the support plate, lift one end and place it on top of multiple support wheels. As the support wheels are compressed, they move towards the bottom of the chute, simultaneously causing the auxiliary wheels to press against the support components. When the outer side of the support wheel contacts the bottom of the chute, it pushes the object towards the top of the trolley. Because the support wheels are compressed and in contact with the bottom of the chute, the movement of the object causes the support wheels to roll inside the chute. This structure reduces the friction between the object and the support plate, making it easier for workers to transport heavy objects to the top of the trolley, thus improving the efficiency of handling to some extent.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Depend on Figures 1-6As shown, this utility model includes a trolley body 1 for transporting heavy objects. The trolley body 1 has a support structure on one side to facilitate the sliding of items to the top of the trolley body 1. The support structure includes a support plate 2, a rotating assembly, multiple support wheels 3, and multiple support members. One end of the support plate 2 has a mounting groove 4 for mounting the rotating assembly, and both ends of the rotating assembly are rotatably connected to the inner sides of the mounting groove 4. The top of the support plate 2 has multiple sliding grooves 5 for the support wheels 3 to roll, and both sides of the sliding grooves 5 have grooves 6 for mounting the support members. The bottoms of the multiple support members are fixedly connected to the bottom ends of the multiple grooves 6. Each support wheel 3 has a connecting post 7 on both sides. The end of the connecting post 7 away from the support wheel 3 has an auxiliary wheel 8, which is rotatably connected to the connecting post 7. The top of the support member has a limiting groove 9 for the auxiliary wheel 8 to slide. The end of the support plate 2 away from the mounting groove 4 has a connecting plate 10. The top of the connecting plate 10 is inclined. When carrying heavy objects, one end of the heavy object is placed on the top of the connecting plate 10, and the heavy object slides along the inclined surface of the top of the connecting plate 10 to the top of the support plate 2. When the heavy object slides to the top of the support plate 2, one end of the heavy object is lifted and placed on the top of multiple support wheels 3. When the support wheels 3 are squeezed, they will move towards the bottom of the slide groove 5, and at the same time, they will drive the auxiliary wheel 8 to squeeze the support rod 11, causing the support rod 11 to move towards the bottom of the groove 6 and squeeze the spring 12. When the outer side of the support wheel 3 contacts the bottom of the slide groove 5, it pushes the heavy object to the top of the trolley body 1. Since the support wheel 3 is squeezed and in contact with the bottom of the slide groove 5, the support wheel 3 will roll inside the slide groove 5 while the heavy object moves, so that the friction between the heavy object and the support plate 2 changes from sliding friction to rolling friction, making it easier for the staff to transport the heavy object to the top of the trolley body 1.

[0025] The support includes a support rod 11 and multiple springs 12. The support rod 11 is located inside the groove 6, and the top of the support rod 11 is provided with a limiting groove 9 for the auxiliary wheel 8 to slide. One end of each of the multiple springs 12 is fixedly connected to the bottom of the support rod 11, and the end of each of the multiple springs 12 away from the support rod 11 is fixedly connected to the bottom of the groove 6. The outer side of the auxiliary wheel 8 is in contact with the inner side of the limiting groove 9. The surface of the support plate 2 is provided with multiple anti-slip strips 13. The multiple anti-slip strips 13 on the surface of the support plate 2 can block the heavy object and prevent one end of the heavy object from sliding towards the connecting plate 10 when it contacts the surface of the support plate 2.

[0026] The rotating assembly includes a fixed column 14, a connecting rod 15, and a sleeve 16. The two ends of the fixed column 14 are fixedly connected to the two sides inside the mounting groove 4, and the sleeve 16 is sleeved on the outside of the fixed column 14. The sleeve 16 is rotatably connected to the fixed column 14. One side of the connecting rod 15 is fixedly connected to the outside of the sleeve 16, and the side of the connecting rod 15 away from the sleeve 16 is fixedly connected to one side of the trolley body 1. After the heavy object is transported, the support plate 2 is pulled, so that the fixed column 14 located inside the mounting groove 4 rotates inside the sleeve 16. The rotation of the fixed column 14 drives the support plate 2 to flip, so that the support plate 2 stands upright. The upright support plate 2 can block the heavy object on the top of the trolley body 1.

[0027] Both sides of the support plate 2 are provided with a locking structure, which includes a limiting member, a fixing block 17, and a connecting block 18. One side of the fixing block 17 is fixedly connected to one side of the support plate 2, and the bottom of the connecting block 18 is fixedly connected to the top of the fixing block 17. The top of the connecting block 18 is provided with a locking block 19. The top of the trolley body 1 is provided with multiple slots 20 that match the shape of the locking blocks 19. One side of the slot 20 is provided with a fixing groove 21 for installing the limiting member. One end of the limiting member is fixedly connected to one side of the fixing groove 21. The limiting member includes a second spring 22 and a limiting block 23. One end of the limiting block 23 is located inside the fixing groove 21. One end of the second spring 22 is fixedly connected to the end of the limiting block 23 located inside the fixing groove 21. The end of the second spring 22 away from the limiting block 23 is fixedly connected to one side of the fixing groove 21. The top of the limiting block 23 is inclined.

[0028] Working principle:

[0029] When moving heavy objects, place one end of the heavy object on the top of the connecting plate 10, and let the heavy object slide along the inclined surface of the top of the connecting plate 10 to the top of the support plate 2. When the heavy object slides to the top of the support plate 2, lift one end of the heavy object and place it on the top of multiple support wheels 3. When the support wheels 3 are squeezed, they will move towards the bottom of the slide groove 5, and at the same time, they will drive the auxiliary wheel 8 to squeeze the support rod 11, causing the support rod 11 to move towards the bottom of the groove 6 and squeeze the spring 12. When the outer side of the support wheel 3 contacts the bottom of the slide groove 5, it pushes the heavy object to the top of the trolley body 1. Since the support wheel 3 is squeezed and in contact with the bottom of the slide groove 5, the support wheel 3 will roll inside the slide groove 5 while the heavy object moves, so that the friction between the heavy object and the support plate 2 changes from sliding friction to rolling friction, making it easier for the staff to transport the heavy object to the top of the trolley body 1.

[0030] It should be noted that while the support wheel 3 is rolling, it will drive the auxiliary wheel 8 to roll inside the limiting groove 9 opened at the top of the support rod 11. The two auxiliary wheels 8 are respectively located on both sides of the support wheel 3. The two auxiliary wheels 8 can support the support wheel 3. The rolling of the auxiliary wheels 8 can further improve the stability of the support wheel 3 when rolling. Under the elastic action of the spring 12, the support rod 11 and the auxiliary wheels 8 can be driven to reset. When the heavy object comes into contact with the support wheel 3, due to the elasticity of the spring 12 itself, the support wheel 3 will move towards the bottom of the groove 5, thereby reducing the direct impact force of the heavy object on the support wheel 3 and ensuring the service life of the support wheel 3.

[0031] Multiple anti-slip strips 13 provided on the surface of the support plate 2 can block the heavy object and prevent one end of the heavy object from sliding towards the connecting plate 10 when it comes into contact with the surface of the support plate 2.

[0032] After the heavy object is moved, pull the support plate 2, causing the fixing column 14 located inside the mounting groove 4 to rotate inside the sleeve 16. The rotation of the fixing column 14 causes the support plate 2 to flip, thus making the support plate 2 stand upright. The upright support plate 2 can block the heavy object on the top of the trolley body 1. When the support plate 2 flips, the fixing block 17 on one side of the support plate 2 will rotate along the central axis of the fixing column 14, thereby driving the connecting block 18 and the locking block 19 to move towards the top of the trolley body 1. When one end of the locking block 19 moves to the top of the trolley body 1, the weight of the heavy object on the top of the trolley body 1 will be reduced. When the slot 20 at the top of the trolley body 1 comes into contact with the inclined surface of the top of the limiting block 23, the limiting block 23 will be pushed into the fixed groove 21 by the pressing of the locking block 19 and will press the spring 22, so that the locking block 19 can continue to move into the slot 20. When the locking block 19 is no longer in contact with the limiting block 23, the limiting block 23 will be reset by the elastic action of the spring 22. The limiting block 23 will block the locking block 19 and prevent the locking block 19 from falling out of the slot 20 due to shaking.
