[0002] A handcart is a transport vehicle that is pushed and pulled by manpower. It is the ancestor of all vehicles. Although the material handling technology of handcarts is constantly developing, handcarts are still used as an indispensable transport tool. Handcarts are widely used in production and life because they are low-cost, simple to maintain, easy to operate, and light in weight. They can work in places where motor vehicles are inconvenient to use, and are very convenient for transporting lighter items over short distances.

[0003] The existing hand truck adopts the method of directly placing the bucket on the frame for fixing. This may easily lead to displacement of the bucket due to the inertia of the goods when loading the bucket. Then, manpower is needed to move the bucket to reset the bucket. In order to solve this problem, the free end of the bucket is usually fixed by a cable tie or wire to ensure that the position of the bucket is fixed. However, when unloading is required, the cable tie or wire needs to be removed, which affects the reliability of the bucket transportation. Moreover, when the bucket needs to be disassembled, the wire or cable tie needs to be damaged, which affects the disassembly and unloading effect of the bucket.

The trolley can be pushed to move by manually operating the pushing handle. At the same time, when the bucket 1 and the frame 2 need to be separated, the bucket 1 and the frame 2 are separated by manually operating the switching handle (similar to the brake handle structure, which will not be repeated here), and the lock of the bucket 1 and the frame 2 is released. The working end of the switching handle is connected to a tensioning wire 9, and the end of the tensioning wire 9 away from the switching handle is provided with a clamping column, and the clamping column is slidably connected to On the frame 2, by pulling the tensioning wire 9, the extension and retraction control of the clamping column 8 is achieved, thereby ensuring the locking and unlocking of the bucket 1; the bucket 1 is detachably connected to the frame 2, and the bottom of the bucket 1 is provided with a clamping hole 12 corresponding to the clamping column 8. The clamping column 8 is inserted into the inside of the clamping hole 12 after the bucket 1 is installed, thereby achieving the clamping fixation of the position of the bucket 1 to prevent the bucket 1 from being displaced during transportation and loading, which affects the transportation of the bucket 1. The switching handle rotates to pull the clamping column 8 to extend and retract on the frame 2, thereby achieving the locking and unlocking process of the bucket 1.

[0020] See also Figure 1 , Figure 2 and Figure 3 Preferably, a limiting flange is provided at the bottom of the clamping column 8 of the utility model, and a tension spring 10 is provided between the limiting flange and the frame 2. The tension spring 10 ensures the reset force of the clamping column 8, so that when the switching handle is released, the clamping column 8 can be reset under the action of the tension spring 10 and inserted into the inside of the clamping hole 12 to clamp and fix the bucket 1. The tension wire 9 is fixed to the bottom of the clamping column 8, and the end of the bucket 1 away from the clamping column 8 is rotatably buckled on the front end of the frame 2. A buckle groove 13 is provided at the front end of the truck bed 1, and a hook 21 is provided at the front end of the frame 2. When installing the truck bed 1, the buckle groove 13 is matched with the hook 21 so that the hook 21 hooks the buckle groove 13 to fix the front end of the truck bed 1. The bottom of the frame 2 is rotatably connected to a guide wheel 23, and the tensioning wire 9 is wound around the outer edge of the guide wheel 23. The outer edge of the guide wheel is provided with a trapezoidal groove for limiting the position of the tensioning wire 9, so as to ensure that the tensioning wire 9 can be in a tensioned state at all times and the tensioning wire 9 will not be misplaced, thereby affecting the pulling process of the clamping column 8.

[0021] In addition, the bottom of the frame 2 of the utility model is provided with a mounting portion 22, and a driving rod 4 is rotatably connected to the mounting portion 22, and a push rod 7 is provided on the driving rod 4. The driving rod 4 drives the push rod 7 to rise and fall and pushes the bucket 1 to rise and fall, ensuring that when the bucket 1 needs to be disassembled or unloaded, the driving rod 4 is rotated to drive the push rod 7 to lift the bucket 1, which is convenient for the disassembly and unloading process of the bucket 1. At the same time, a guide portion 11 is provided on the bottom outer edge of the bucket 1 to ensure that the bucket 1 can be buckled on the top of the frame 2 in the horizontal direction to complete the installation process of the bucket 1.

[0022] Furthermore, the driving rod 4 of the utility model is a screw rod, on which an adjusting sleeve 5 is screwed, and two push rods 7 are provided, one of which is rotatably connected to the adjusting sleeve 5, and the other push rod 7 is hinged to the mounting portion 22, and a push block 6 is hinged between the two push rods 7. The driving rod 4 rotates to drive the adjusting sleeve 5 to slide, and the adjusting sleeve 5 is moved on the screw rod by rotating the driving rod 4, thereby controlling the position between the adjusting sleeve 5 and the hinged seat 24, and further adjusting the position of the push block 6 at the front end of the push rod 7 to achieve the control of the position of the truck bucket 1.

[0023] See also Figure 4 Better yet, the bottom of the frame 2 of the utility model is rotatably connected to a roller 3, the frame 2 is provided with a supporting leg at one end adjacent to the pushing handle, the top of the top block 6 is provided with a top plate 62, and the bottom of the top block 6 is provided with a limiting portion 61. The position of the top block 6 is limited by the limiting portion 61 to prevent the top rod 7 from getting stuck and affecting the use of the top rod 7. At the same time, the top of the top plate 62 is close to the bottom of the bucket 1 to push the bucket 1 to rotate.

[0024] In this embodiment, combined with Figure 1 to Figure 4 When in use, the bucket 1 is installed on the frame 2 by matching the buckle groove 13 and the hook 21, and then the clamping hole 12 at the bottom of the bucket 1 matches the clamping column 8 to position the bucket 1 to prevent the bucket 1 from being displaced. At the same time, when it is necessary to disassemble the bucket 1 or unload, the switching handle is manually turned to pull the clamping column 8 back into the frame 2. At this time, the bucket 1 is loosened, and the rotating handle at the end of the driving rod 4 is turned to drive the jack 7 to lift the bucket 1, which is convenient for disassembling the bucket 1 and unloading.
