Description

Technical Field

[0001] The utility model relates to the technical field of transport carts, and more specifically to a road cargo transport cart. Background Art

[0002] A handcart is a transport vehicle that is pushed and pulled by manpower. It is the ancestor of all vehicles. Handcarts are widely used in production and life because they are low-cost, simple to maintain, easy to operate, light in weight, and can work in places where motor vehicles are inconvenient to use.

[0003] When using existing road cargo transport carts, due to the fixed size of the cart loading plate, the cargo cannot be stably placed when encountering large-volume cargo. The cargo is prone to shaking during transportation, and the stability of the cargo cannot be guaranteed. At the same time, when a large amount of cargo needs to be transported at one time, due to the limited width of the loading plate, the cargo can only be piled high for transportation. The high-pile cargo has very poor stability during transportation and is prone to collapse and fall, which will cause damage to the cargo. Therefore, there are limitations in its use.

[0004] In view of this, we propose a road cargo transport cart. Utility Model Content

[0027] See also Figure 1-4 ,The utility model provides a technical solution:

[0028] A road cargo transport cart comprises a body 1, a rotating rod 2 is rotatably arranged on the inner side of the body 1, a gear 3 is fixedly sleeved on the outer side of the rotating rod 2, two groups of tooth plates 4 are movably arranged on the outer side of the gear 3, the two groups of tooth plates 4 are meshed with the gear 3 in sequence, and an extension plate 5 is fixedly arranged on the outer side of the tooth plate 4, the extension plate 5 movably passes through the body 1 and extends to the outside, and limit blocks 6 are fixedly arranged on both sides of the extension plate 5, and limit grooves 7 for docking with the limit blocks 6 are opened on both sides of the body 1, and the limit blocks 6 slide in the limit grooves 7, the rotating rod 2 movably passes through the body 1 and extends to the lower side, and a connecting plate 11 is fixedly arranged on the outer end of the rotating rod 2 located at the lower part of the body 1, and by arranging two groups of flexibly adjustable extension plates 5, the extension plates 5 can be flexibly adjusted and used according to usage requirements, so that goods of different volumes can be better transported, and the stability and safety of cargo transportation are improved.

[0029] Specifically, a slide bar 8 is fixedly provided inside the limiting groove 7 , and the slide bar 8 movably passes through the two groups of limiting blocks 6 . The slide bar 8 can limit the limiting blocks 6 , so that the limiting blocks 6 move along the slide bar 8 , thereby further improving the use stability of the extension plate 5 .

[0030] Furthermore, an anti-slip block 9 is fixedly provided on the outer side of the tooth plate 4, and a through groove 10 for docking with the anti-slip block 9 is provided on the inner side of the extension plate 5. By providing the anti-slip block 9, the tooth plate 4 can be limited to prevent the tooth plate 4 from detaching from the gear 3, thereby ensuring the normal use of the device.

[0031] It is worth noting that a connecting rod 12 is fixedly provided on the outside of the connecting disk 11, and a grab handle 13 is fixedly provided on the outer end of the connecting rod 12. The grab handle 13 can be provided to facilitate the rotation of the connecting disk 11 and the gear 3, thereby improving the convenience of operation.

[0032] It is worth noting that a movable block 14 is movably provided on the inner side of the grab 13, and a positioning rod 15 is fixedly provided on the upper side of the movable block 14. The positioning rod 15 movably passes through the grab 13 and extends to the upper side. A plurality of positioning grooves 16 for docking with the positioning rod 15 are provided on the lower side of the vehicle body 1. By setting the positioning rod 15 and inserting the positioning groove 16, the extension plate 5 can be conveniently adjusted and fixed at the same time, and the use is very flexible and convenient.

[0033] In addition, a fixed cylinder 17 is fixedly provided on the inner side of the grab handle 13, and a movable rod 18 is movably inserted into the inner side of the fixed cylinder 17. The movable rod 18 movably passes through the fixed cylinder 17 and extends to the outside, and the outer end of the movable rod 18 is located at the outer part of the fixed cylinder 17 and is fixedly connected to the movable block 14. A spring 19 is provided on the inner side of the fixed cylinder 17, one end of the spring 19 is connected to the inner side of the fixed cylinder 17, and the other end of the spring 19 is connected to the movable rod 18. The spring 19 does not deform in the initial state. When the movable block 14 is pressed, the movable rod 18 is driven to move and squeeze the spring 19. At this time, the spring 19 is deformed, thereby facilitating the positioning rod 15 to move out of the positioning groove 16. When the movable block 14 is released, the elastic potential energy of the spring 19 is released, thereby being able to drive the positioning rod 15 to be quickly inserted into the positioning groove 16. While improving the convenience of the positioning rod 15 being inserted into the positioning groove 16, the insertion stability is also improved, thereby ensuring the stability of the extension plate 5 in use.

[0034] It must be mentioned that two groups of thumb grooves 20 are provided on the upper side of the movable block 14, and anti-slip pads are provided on the upper sides of the two groups of thumb grooves 20. By providing the thumb grooves 20, the movable block 14 can be pressed conveniently with the thumbs, further improving the convenience of use.

[0035] Working principle: first insert the finger into the inner side of the grip 13, then place the thumb on the upper side of the thumb groove 20, and then press the movable block 14. The movable block 14 is pressed to drive the movable rod 18 to move into the fixed tube 17 and squeeze the spring 19, and the movable block 14 drives the positioning rod 15 to move downward and move out of the positioning groove 16 when moving. Then, the connecting rod 12 can be rotated by the grip 13. When the connecting rod 12 rotates, it drives the connecting disk 11 to rotate. The rotation of the connecting disk 11 drives the rotating rod 2 and the gear 3 to rotate. When the gear 3 rotates, it drives the two sets of tooth plates 4 to move, and the two sets of tooth plates 4 can drive the two sets of extension plates 5 to move, so as to facilitate the adjustment of the use width of the vehicle body 1. After adjusting the use width, the movable block 14 is released. At this time, the spring 19 stretches and resets and drives the movable rod 18 and the movable block 14 to move upward. When the movable block 14 moves upward, it drives the positioning rod 15 to be inserted into the positioning groove 16 again, so that the two sets of extension plates 5 can be fixed to ensure the stability of the extension plates 5.
