Technical Field
[0001] This utility model relates to the field of logistics warehousing and sorting technology, and in particular to a pallet cart for logistics warehousing and sorting. Background Technology
[0002] In logistics warehousing and sorting operations, pallet trucks are key equipment for short-distance transportation and handling of goods, and the height of their handrails directly affects the comfort and work efficiency of operators.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the handrails of existing logistics warehousing and sorting pallet trucks are mostly made of one-piece welding or bolt rigid fixing structure. This design fixes the height of the handrail to a single size, which cannot be adjusted according to the height of the operator, operating habits or work scenario, thereby reducing the comfort of the operator and the work efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing pallet carts used for logistics warehousing and sorting have handrails that are mostly integrally welded or rigidly fixed with bolts. This design makes the height of the handrail fixed to a single size, which cannot be adjusted according to the height of the operator, operating habits or work scenarios, thus reducing the comfort of the operator and the efficiency of work. Therefore, we propose a pallet cart for logistics warehousing and sorting.
[0005] To achieve the above objectives, this application adopts the following technical solution: a pallet cart for logistics warehousing and sorting, comprising a rotator: a hollow rod is fixedly connected to the top of the rotator, a connecting rod is slidably connected inside the hollow rod, handrails are fixedly connected to both sides of the connecting rod, a pallet frame is fixedly connected to one side of the rotator, rollers are installed at the bottom of the rotator, a slot is opened on one side of the hollow rod, multiple insertion slots are opened at both ends of the inner cavity of the slot, a square groove is opened on one side of the connecting rod, a square plate is fixedly connected inside the square groove, two adjusting blocks are slidably connected inside the square plate, a connecting plate is fixedly connected to one side of the adjusting block, and an insertion block is fixedly connected to one end of the connecting plate.
[0006] Preferably, a limiting rod is fixedly connected inside the square groove, and a limiting hole is opened at one end of the connecting plate, with the inside of the limiting hole slidably connected to the surface of the limiting rod.
[0007] Preferably, a return spring is fixedly connected to one end of the connecting plate, and one end of the return spring is fixedly connected to the inside of the square groove.
[0008] Preferably, the surface of the plug block is slidably connected to the interior of the plug groove, and the external shape of the plug block matches the internal shape of the plug groove.
[0009] Preferably, the hollow rod has limiting grooves on both sides of its inner cavity, and limiting blocks are fixedly connected to both sides of the connecting rod, with the surface of the limiting blocks slidably connected to the inside of the limiting grooves.
[0010] Preferably, a push-out spring is fixedly connected to the bottom of the connecting rod, and the bottom of the push-out spring is fixedly connected to the bottom of the inner cavity of the hollow rod.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] In this invention, the operator moves the connecting rod, causing it to slide inside the hollow rod. Once the position of the connecting rod is determined, the operator can move the adjusting block, which in turn moves the connecting plate, causing the connecting plate to insert the plug into the plug slot, thereby fixing the position of the connecting rod. This allows the height of the handrail to be adjusted, making it usable by operators of different heights and increasing the practicality of the device. Attached Figure Description

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.
[0020] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a pallet cart for logistics warehousing and sorting, including a rotator 1; a hollow rod 2 is fixedly connected to the top of the rotator 1, a connecting rod 3 is slidably connected inside the hollow rod 2, handrails 4 are fixedly connected to both sides of the connecting rod 3, a pallet frame 5 is fixedly connected to one side of the rotator 1, rollers 6 are installed at the bottom of the rotator 1, a slot 7 is opened on one side of the hollow rod 2, multiple insertion slots 8 are opened at both ends of the inner cavity of the slot 7, a square groove 9 is opened on one side of the connecting rod 3, a square plate 10 is fixedly connected inside the square groove 9, and a sliding connection is made inside the square plate 10. Two adjusting blocks 11 are provided. A connecting plate 12 is fixedly connected to one side of the adjusting block 11, and a plug-in block 13 is fixedly connected to one end of the connecting plate 12. The operator moves the connecting rod 3, causing it to slide inside the hollow rod 2. Once the position of the connecting rod 3 is determined, the adjusting block 11 can be moved to move the connecting plate 12, causing the connecting plate 12 to insert the plug-in block 13 into the plug-in slot 8, thereby fixing the position of the connecting rod 3. This allows the height of the handrail 4 to be adjusted, making it usable by operators of different heights and increasing the practicality of the device.
[0021] Reference Figure 4 As shown in this embodiment: a limiting rod 15 is fixedly connected inside the square groove 9, and a limiting hole 14 is opened at one end of the connecting plate 12. The inside of the limiting hole 14 is slidably connected to the surface of the limiting rod 15. By setting the limiting rod 15 and the limiting hole 14, the connecting plate 12 is more stable when moving, avoiding the phenomenon of the connecting plate 12 shifting or shaking during the movement, and improving the stability of the connecting rod 3. At the same time, when the operator moves the adjusting block 11, the adjusting block 11 drives the connecting plate 12 to slide on the surface of the limiting rod 15, making the movement trajectory of the connecting plate 12 clearer.
[0022] Reference Figure 4As shown in this embodiment: a return spring 16 is fixedly connected to one end of the connecting plate 12. One end of the return spring 16 is fixedly connected to the inside of the square groove 9. By setting the return spring 16, when the staff adjusts the height of the handrail 4 and releases the adjusting block 11, the elastic force of the return spring 16 will push the connecting plate 12 to return to its original position, so that the plug block 13 is tightly inserted into the inside of the plug groove 8, fixing the position of the connecting rod 3 and preventing the handrail 4 from shaking during use.
[0023] Reference Figure 2 and Figure 4 As shown in this embodiment: the surface of the plug block 13 is slidably connected to the inside of the plug groove 8, and the external shape of the plug block 13 matches the internal shape of the plug groove 8. By designing the sliding connection between the plug block 13 and the plug groove 8, the connecting rod 3 is more convenient and efficient in the fixing process. During operation, the operator only needs to move the adjusting block 11, which will drive the connecting plate 12 and the plug block 13 to slide in the plug groove 8 until the plug block 13 is completely embedded in the plug groove 8, thereby achieving a stable fixation of the connecting rod 3, simplifying the operation process and improving the ease of use of the pallet truck.
[0024] Reference Figure 2 and Figure 3 As shown in this embodiment: both sides of the inner cavity of the hollow rod 2 are provided with limiting grooves 17, and both sides of the connecting rod 3 are fixedly connected with limiting blocks 18. The surface of the limiting block 18 is slidably connected to the inside of the limiting groove 17. By designing the sliding connection between the limiting groove 17 and the limiting block 18, the stability of the connecting rod 3 in the inner cavity of the hollow rod 2 is enhanced, ensuring that the handrail 4 will not shift due to external force after the height is adjusted, and further improving the safety of the pallet truck.
[0025] Reference Figure 2 As shown in this embodiment: the bottom of the connecting rod 3 is fixedly connected to the ejector spring 19, and the bottom of the ejector spring 19 is fixedly connected to the bottom of the inner cavity of the hollow rod 2. By designing the ejector spring 19, when the height of the handrail 4 needs to be adjusted, the ejector spring 19 can provide an upward thrust to the connecting rod 3, so that the connecting rod 3 can easily move from one height position to another height position in the inner cavity of the hollow rod 2, reducing the difficulty of operation.
[0026] Working principle: The operator moves the connecting rod 3, causing it to slide inside the hollow rod 2. Once the position of the connecting rod 3 is determined, the operator can move the adjusting block 11, which in turn moves the connecting plate 12. This causes the connecting plate 12 to insert the insertion block 13 into the insertion slot 8, thus fixing the position of the connecting rod 3. This allows the height of the handrail 4 to be adjusted, making it usable for operators of different heights and increasing the practicality of the device. The limiting rod 15 and limiting hole 14 ensure stability during movement of the connecting plate 12, preventing displacement or wobbling and improving the stability of the connecting rod 3. Simultaneously, when the operator moves the adjusting block 11, it causes the connecting plate 12 to slide on the surface of the limiting rod 15, making the movement trajectory of the connecting plate 12 clearer. A return spring 16 is provided; after the operator adjusts the height of the handrail 4, releasing the adjusting block 11 causes the return spring 16 to push the connecting plate 12 back to its original position, thus fixing the insertion block 13. Block 13 is tightly inserted into the insertion slot 8 to fix the position of the connecting rod 3, preventing the handrail 4 from shaking during use. By designing a sliding connection between the insertion block 13 and the insertion slot 8, the fixing of the connecting rod 3 is made more convenient and efficient. During operation, the operator only needs to move the adjusting block 11, which in turn drives the connecting plate 12 and the insertion block 13 to slide in the insertion slot 8 until the insertion block 13 is fully embedded in the insertion slot 8, thus achieving a stable fixation of the connecting rod 3, simplifying the operation process and improving the ease of use of the pallet truck. By designing a sliding connection between the limiting slot 17 and the limiting block 18, the stability of the connecting rod 3 in the cavity of the hollow rod 2 is enhanced, ensuring that the handrail 4 will not shift due to external force after the height is adjusted, further improving the safety of the pallet truck. By designing an ejector spring 19, when the height of the handrail 4 needs to be adjusted, the ejector spring 19 can provide an upward thrust to the connecting rod 3, allowing the connecting rod 3 to easily move from one height position to another in the cavity of the hollow rod 2, reducing the difficulty of operation.
[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
