[0022] The present utility model will be described in detail below with reference to the accompanying drawings.
[0023] Embodiment 1: A detachable trolley convenient for transportation, as Figure 1 - Figure 2 shown, includes a frame 1. A plurality of mounting rods 2 are fixedly connected to the lower end surface of the frame 1. An installation frame 3 is arranged on the mounting rods 2. A wheel 4 is rotatably connected to the installation frame 3. A convex rod 5 is arranged on one side of the installation frame 3 close to the wheel 4. A groove 6 for inserting the convex rod 5 is opened at one end of the mounting rod 2 close to the installation frame 3. A connecting piece is arranged between the mounting rod 2 and the installation frame 3. When the convex rod 5 is inserted into the groove 6, the mounting rod 2 and the installation frame 3 are detachably connected through the connecting piece.
[0024] The connecting piece includes a housing 7 rotatably connected to one end of the installation frame 3. A recessed groove 8 is opened at one end of the housing 7 close to the mounting rod 2. The convex rod 5 is fixedly connected to the bottom wall of the recessed groove 8. An external thread 9 is arranged on the surface of the convex rod 5. An internal thread 10 matching the external thread 9 is arranged on the inner wall of the groove 6.
[0025] Working principle: Under normal circumstances, the mounting bracket 3 is installed on the mounting rod 2, and the wheel 4 can be used normally. When the mounting bracket 3 and the wheel 4 need to be disassembled during the handling process, hold the outer housing 7 and rotate it. The outer housing 7 can drive the convex rod 5 fixed to it to rotate together. Since the external thread 9 on the convex rod 5 and the internal thread 10 of the groove 6 are in threaded fit connection, the convex rod 5 can be rotated out of the groove 6 and separated from the mounting rod 2. The mounting bracket 3 and the wheel 4 can be disassembled, reducing the volume of the trolley, improving the packing rate of the trolley, and reducing the transportation cost.
[0026] After the transportation is completed, when the wheel 4 and the mounting bracket 3 need to be reinstalled on the mounting rod 2, also hold the outer housing 7 and drive the convex rod 5 to rotate, so that the convex rod 5 can be rotated back into the groove 6. During the entire disassembly and assembly process, no external tools such as screwdrivers are required, the disassembly and assembly are more convenient, and there are no scattered other parts, so it is not easy to lose accessories.
[0027] Embodiment 2: Compared with Embodiment 1, the difference in Embodiment 2 is that the structure of the connecting piece is different. As Figure 3 - Figure 4 shown, in Embodiment 2, the connecting piece includes a receiving groove 11 provided on the outer wall of the mounting rod 2. A number of "L"-shaped buckles 12 distributed in a circular array are rotatably connected in the receiving groove 11. A first convex rib 13 is fixedly connected to the inner wall of the buckle 12. A number of grooves 14 distributed in a circular array are provided on the outer wall of the convex rod 5. The number and position of the grooves 14 correspond to those of the buckles 12. A second convex rib 16 that is engaged with the first convex rib 13 is fixedly connected to the inner wall of the groove 14. Through grooves 15 corresponding to the number and position of the grooves 14 are opened on the inner wall of the groove 6, and the through grooves 15 communicate with the outside.
[0028] A limiting strip 17 is fixedly connected to the outer wall of the convex rod 5, and a limiting groove 18 for inserting the limiting strip 17 is provided on the inner wall of the groove 6.
[0029] A first magnetic part 19 is fixedly connected to the outer wall of the buckle 12, a second magnetic part 20 that adsorbs with the first magnetic part 19 is fixedly connected to the inner wall of the receiving groove 11, and a notch plate 21 is fixedly connected to the outer wall of the buckle 12.
[0030] In the second embodiment, when the mounting frame 3 needs to be separated from the mounting rod 2, first insert a finger into the notch formed by the notch plate 21, pry the buckle 12 outward, separate the convex rib 13 from the convex rib 2 16, rotate the buckle 12 outward to open it, and after the buckle 12 and the convex rib 1 13 are no longer limited, the convex rod 5 can be pulled out of the groove 6, and the mounting frame 3 and the wheel 4 can be disassembled. The buckle 12 after being rotated and opened can be turned upward by 180 degrees, so that the magnetic suction piece 19 and the magnetic suction piece 20 are adsorbed together, and one side of the buckle 12 is kept in a state of being in contact with the inner wall of the receiving groove 11, so that the buckle 12 can be stored more neatly, which can reduce the volume of the cart during transportation and save transportation costs.
[0031] After the transportation is completed, when the wheel 4 and the mounting frame 3 need to be reconnected to the mounting rod 2, align the limit strip 17 with the limit rod, and then insert the protruding rod 5 into the groove 6. The cooperation between the limit strip 17 and the limit rod can make the slot 14 correspond to the position of the through slot 15 when the protruding rod 5 is inserted. Then, rotate the buckle 12 downward to separate the magnetic suction piece 19 from the magnetic suction piece 20, so that the buckle 12 is re-inserted into the slot 14, and the convex ridge 13 and the convex ridge 2 16 are buckled together to fix the protruding rod 5 and the mounting frame 3. No external tools are required during the entire disassembly and assembly process, making disassembly and assembly more convenient.
[0032] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
