Description

Technical Field

[0001] The utility model relates to the technical field of steering wheels, in particular to a steering wheel structure of a cleaning machine. Background Art

[0002] Cleaning machines are used to flush and filter pollutants generated or invaded during the manufacturing, assembly, use and maintenance of hydraulic systems. They can also be used for regular maintenance and filtration of working oils to improve cleanliness, avoid or reduce failures caused by pollution, thereby ensuring the high performance, high reliability and long life of hydraulic system equipment. Cleaning machines are mainly divided into four types: hydraulic cleaning machines, high-pressure cleaning machines, ultrasonic cleaning machines and spray cleaning machines. Steering wheels, also known as universal wheels, are usually installed at the bottom corners of the cleaning machines to facilitate personnel pushing. Universal wheels are so-called movable casters, and their structure allows 360-degree horizontal rotation. Casters are a general term. Most of the existing universal wheels do not have a self-locking structure, which will cause the universal wheels to be unrestricted and prone to movement and deviation, which is extremely inconvenient. Although personnel can use universal wheels to push some objects normally, it is often time-consuming and laborious to fix the position when stopping.

[0003] In order to solve the above technical problems, a Chinese patent with announcement number CN213291885U in the prior art discloses a universal wheel, including a wheel body bracket, a connecting shaft is provided at the lower part of the wheel body bracket, a wheel body is sleeved on the connecting shaft, two ends of the connecting shaft respectively pass through the lower two sides of the wheel body bracket, and two ends of the connecting shaft located on the outer side of the wheel body bracket are fixedly connected to the wheel body bracket by bolts.

[0004] Although the above-mentioned prior art solution has advantages, both ends of the connecting shaft located on the outside of the wheel body bracket are fixedly connected to the wheel body bracket by bolts. When the wheel body is bumped and worn after a period of use, resulting in poor movement, personnel are required to disassemble and replace it in time. However, during disassembly and assembly, the staff are required to twist the locking bolts and matching nuts one by one, which is relatively cumbersome and affects the efficiency of disassembly and replacement.

[0026] In this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, the clamping assembly includes a mounting groove opened inside another group of lap plates 5, the inner side of the mounting groove is connected to the inner side of the docking groove, a movable rod 8 is rotatably connected to one side of the inner wall of the mounting groove, an extrusion block 9 is sleeved on the outer side of the movable rod 8, a second inclined surface that fits the first inclined surface is opened on one side of the extrusion block 9, a positioning groove is opened on one side of the extrusion block 9 corresponding to the second inclined surface, a positioning rod is rotatably connected to the inner side of the positioning groove, a positioning plate 10 is sleeved on the outer side of the positioning rod, a third inclined surface is opened on one side of the positioning plate 10, a torsion spring is installed at one end of the outer side of the positioning rod, a fixing groove is opened on the outer wall of the extrusion block 9 located on one side of the positioning groove, a fixing rod is installed on the inner side of the fixing groove, a first spring 11 is installed on the outer side of the fixing rod, and the other end of the first spring 11 is installed on the inner wall of the mounting groove, and one side of the docking block 6 corresponds to the first inclined surface A locking groove is provided at the end of the extrusion block 9, a limiting plate 16 is installed at one end of the extrusion block 9, and a limiting groove slidably connected to the limiting plate 16 is provided on the inner wall of the installation groove. Then, the two sets of lap plates 5 are squeezed close to each other, so that the first inclined surface, the second inclined surface and the third inclined surface are in contact, so that the extrusion block 9 cooperates with the limiting plate 16 and the limiting groove to expand around the movable rod 8. At the same time, the first spring 11 is also stretched, and the lap plate 5 continues to be pressed. The first inclined surface presses the third inclined surface on the positioning plate 10, forcing it to retract to the inside of the positioning groove. After it is aligned with the locking groove, the torsion spring rebounds and drives the positioning plate 10 to expand inside the positioning groove. At this time, the rubber pad 7 is in a compressed state, and then the lap plate 5 is released, and the rubber pad 7 rebounds a distance, so that the positioning plate 10 is against the inner wall of the positioning groove, and the positioning and fixation of the wheel 3 can be completed.

Furthermore, when disassembling, buckle the buckle groove 14 to drive the sliding plate 12 to cooperate with the connecting groove 13 and the connecting block to move, so that the magnetic block 15 is separated from the iron block, and then buckle the pull ring to rotate to drive the movable rod 8 to rotate together, so that the extrusion block 9 actively stretches the first spring 11, and the positioning plate 10 can be separated from the positioning groove. At this time, the two groups of lap plates 5 can be separated, and the wheel 3 is removed to complete the disassembly.

Then the lap plate 5 is loosened, and the rubber pad 7 rebounds for a distance, so that the positioning plate 10 is against the inner wall of the positioning groove, and the positioning and fixing of the wheel 3 can be completed. On the contrary, when disassembling, the buckle groove 14 is buckled to drive the sliding plate 12 to cooperate with the connecting groove 13 and the connecting block to move, so that the magnetic block 15 is separated from the iron block. Then, the pull ring is buckled and rotated to drive the movable rod 8 to rotate together, so that the extrusion block 9 actively stretches the first spring 11, and the positioning plate 10 can be separated from the positioning groove. At this time, the two sets of lap plates 5 can be separated, and the wheel 3 is removed to complete the disassembly.
