Description

Technical Field

[0001] This utility model relates to the field of logistics trolley technology, specifically a logistics trolley with expandable space. Background Technology

[0002] Logistics trolleys are a type of transportation tool widely used in the logistics industry, mainly for handling and moving goods. There are various types and specifications of logistics trolleys to meet different logistics needs, but existing logistics trolleys still have certain shortcomings in use.

[0003] In the existing technology, logistics trolleys are an indispensable transportation tool in the logistics industry. Their design and function are to improve logistics efficiency, reduce labor intensity and ensure the safety of goods. During the use of logistics trolleys, the goods to be transported need to be placed on the loading platform. Due to the fixed size of the logistics trolley, the loading space of its loading platform is fixed, which means that the loading platform can only carry and transport a fixed number of goods, making it difficult to transport more goods. Utility Model Content

[0004] The purpose of this utility model is to provide a logistics trolley with expandable space to solve the problem of fixed cargo space size of logistics trolleys currently on the market, as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a space-expandable logistics trolley, comprising: a loading platform, casters, and a push rod. The loading platform has casters mounted on its bottom, and a push rod mounted on its top. A threaded knob is threadedly connected to the outer side of the loading platform near the push rod. An extension plate is slidably connected inside the loading platform. A threaded hole is formed inside the extension plate near the threaded knob. A baffle is connected to the end of the extension plate. A connecting block is connected to the bottom of the extension plate. A sliding rod is connected to the back of the connecting block. A support block is connected to the bottom of the loading platform near the sliding rod. Positioning blocks are connected to the inner sides of both baffles. A convex plate and a concave plate are jointly provided between the two baffles. A locking rod is connected to the side of the convex plate and the concave plate near the baffle.

[0006] Preferably, the locking rod and the positioning block form an insertion structure.

[0007] Preferably, the support block has a through hole that matches the size of the slide rod, and the slide rod and the support block form a sliding structure.

[0008] Preferably, a docking block is welded to the side of the carrier plate away from the threaded knob, and a guide block is provided at the end of the docking block.

[0009] Preferably, the bottom of the guide block is connected to an anti-slip base, and a return spring is connected to the inside of the guide block near the docking block.

[0010] Preferably, one end of the reset spring is connected to a locking block, and a magnetic block is installed inside the guide block near the locking block. The magnetic block and the guide block are an integral structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This expandable logistics trolley can move the corresponding extension plates and positioning blocks when the two sets of baffles move. When the extension plates move, they can move the connecting blocks. When both sets of extension plates slide to their maximum distance, the threaded knob can be tightened. When the locking block is reset, its end can engage with the docking block. At this time, the position of the guide block is not easy to shift, so that heavier goods on the loading plate can be pulled onto the guide block, allowing the goods to slide down the inclined surface of the guide block to the ground. The guide block can assist personnel in unloading heavier goods, saving some labor. At the same time, the anti-slip base can improve the stability of the guide block placement.

[0012] 1. Logistics trolleys play a vital role in various industries such as logistics, warehousing, and retail due to their convenience and practicality. However, traditional logistics trolleys have relatively fixed dimensions and are difficult to extend, making it difficult to transport more goods. When the two sets of baffles move, they can drive the corresponding extension plates and positioning blocks to move. When the extension plates move, they can drive the connecting blocks to move. When both sets of extension plates slide to their maximum distance, the threaded knob can be tightened, allowing the end of the threaded knob to slide into the designated threaded hole. The two sets of extension plates can expand the space for placing the cargo tray. At this time, goods can be placed on the cargo tray and extension plates respectively. After the goods are placed, the locking rods on the convex and concave plates can be inserted into the positioning blocks. The convex and concave plates prevent the goods from falling off during transportation, and the extension plates can expand the space for placing goods on the cargo tray, thereby improving the loading efficiency of the logistics trolley and enabling the transportation of more goods.

[0013] 2. During the use of a logistics trolley, if the loaded goods are heavy, it is difficult for personnel to lift the goods from the loading platform and place them on the ground. When the guide block moves, it can drive the anti-slip base to move as well. When the guide block moves to the end of the docking block, it continues to push the guide block closer to the docking block, so that the end of the docking block can be inserted into the guide block. When the locking block is squeezed, it can compress the return spring. When the return spring is compressed to a certain degree, the end of the docking block can be magnetically attracted to the magnetic block. At this time, the locking block can be reset by the return spring. When the locking block is reset, its end can engage with the docking block. At this time, the position of the guide block is not easy to shift, so the heavier goods on the loading platform can be pulled onto the guide block, allowing the goods to slide down the inclined surface of the guide block to the ground. The guide block can assist personnel in unloading heavier goods, saving some labor. At the same time, the anti-slip base can improve the stability of the guide block. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 As can be seen, this utility model provides a technical solution: a space-expandable logistics trolley, including: a loading platform 1, casters 2, and a push rod 3. The casters 2 are installed at the bottom of the loading platform 1, and the push rod 3 is installed at the top of the loading platform 1. A threaded knob 4 is threadedly connected to the outer side of the loading platform 1 near the push rod 3. An extension plate 5 is slidably connected inside the loading platform 1. A threaded hole 6 is opened inside the extension plate 5 near the threaded knob 4. A baffle 7 is connected to the end of the extension plate 5, and a connecting block 8 is connected to the bottom of the extension plate 5. A sliding rod 9 is connected to the back of the connecting block 8. A support block 10 is connected to the bottom of the carrying plate 1 near the sliding rod 9. A positioning block 11 is connected to the inner side of each of the two baffles 7. A convex plate 12 and a concave plate 13 are provided between the two baffles 7. A locking rod 14 is connected to the side of the convex plate 12 and the concave plate 13 near the baffle 7. The locking rod 14 and the positioning block 11 form an insertion structure. A through hole matching the size of the sliding rod 9 is opened through the inside of the support block 10. A sliding structure is formed between the sliding rod 9 and the support block 10.

[0022] In practice, logistics trolleys play an important role in various industries such as logistics, warehousing, and retail due to their convenience and practicality. However, the space dimensions of traditional logistics trolleys are relatively fixed and difficult to extend, making it difficult for them to transport more goods. Two sets of baffles 7 can be pulled in opposite directions. When the two sets of baffles 7 move, they can drive the corresponding extension plates 5 and positioning blocks 11 to move. When the extension plates 5 move, they can drive the connecting blocks 8 to move. When the connecting blocks 8 move, they can drive the sliding rods 9 to move. When the sliding rods 9 move, they can slide with the support blocks 10. When both sets of extension plates 5 have slid to their maximum distance, the threaded knobs 4 can be tightened so that the end of the threaded knobs 4 can slide into the designated threaded holes 6. The space for placing the carrying plate 1 can be expanded by the two sets of extension plates 5. At this time, goods can be placed on the carrying plate 1 and the extension plates 5 respectively. After the goods are placed, the locking rods 14 on the convex plate 12 and the concave plate 13 can be inserted into the positioning blocks 11.

[0023] See Figures 1-4 It can be seen that the convex plate 12 and concave plate 13 make it less likely for goods to fall off during transportation, and the extension plate 5 can expand the space size for placing goods on the loading plate 1, thereby improving the efficiency of loading goods on the logistics trolley and enabling the transportation of more goods.

[0024] See Figure 1 and Figure 5It can be seen that a docking block 15 is welded to the side of the loading plate 1 away from the threaded knob 4. A guide block 16 is provided at the end of the docking block 15. An anti-slip base 17 is connected to the bottom of the guide block 16. A return spring 18 is connected to the inside of the guide block 16 near the docking block 15. A locking block 19 is connected to one end of the return spring 18. A magnetic block 20 is installed inside the guide block 16 near the locking block 19. The magnetic block 20 and the guide block 16 are an integral structure. The docking block 15 and the magnetic block 20 form a magnetic attraction structure.

[0025] In practical implementation, when the loaded goods on the logistics trolley are heavy, it becomes difficult for personnel to lift the goods from the loading platform 1 and place them on the ground during unloading. In this case, the guide block 16 can be pushed towards the docking block 15. As the guide block 16 moves, it can move the anti-slip base 17. When the guide block 16 reaches the end of the docking block 15, it is pushed closer to the docking block 15, allowing the end of the docking block 15 to be inserted into the guide block 16. The end of the docking block 15 can then press against the inclined surface of the locking block 19. When 9 is squeezed, the return spring 18 can be compressed. When the return spring 18 is compressed to a specified degree, the end of the docking block 15 can be magnetically attracted to the magnetic block 20. At this time, the locking block 19 can be reset by the return spring 18. When the locking block 19 is reset, its end can engage with the docking block 15. At the same time, one side of the guide block 16 can be closely attached to one side of the carrying plate 1. At this time, the position of the guide block 16 is not easy to shift, so that the heavier goods on the carrying plate 1 can be pulled onto the guide block 16, so that the goods can slide down the inclined surface on the guide block 16 to the ground.

[0026] See Figure 1 and Figure 5 It can be seen that the guide block 16 can assist personnel in unloading heavier goods, saving some labor. At the same time, the anti-slip base 17 can improve the stability of the guide block 16.

[0027] In summary, when using this expandable logistics trolley, the two sets of baffles 7 can be pulled in opposite directions. When the two sets of baffles 7 move, they can drive the corresponding extension plate 5 and positioning block 11 to move. When the extension plate 5 moves, it can drive the connecting block 8 to move. The convex plate 12 and concave plate 13 prevent goods from falling off during transportation. The extension plate 5 can expand the space for placing goods on the loading plate 1, thereby improving the efficiency of loading goods on the logistics trolley and allowing more goods to be transported. The guide block 16 can assist personnel in unloading heavier goods, saving some labor. At the same time, the anti-slip base 17 can improve the stability of the guide block 16.
