Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, specifically a cleaning tray. Background Technology
[0002] A cleaning disc is a type of cleaning machine. Its main structure is disc-shaped. It uses a power unit to generate high-pressure water to rinse and remove dirt, thus achieving the purpose of cleaning.
[0003] For example, utility model patent CN219920968U discloses a cleaning tray, including a cleaning tray cover and casters. A connecting plate is rotatably connected to the cleaning tray cover, and the casters are provided on the connecting plate. A limiting device is provided between the cleaning tray cover and the connecting plate to limit the cleaning position of the cleaning tray. When the opening of the cleaning tray cover is downward and the cleaning tray is cleaning downward, the limiting device limits the cleaning tray cover; when the opening of the cleaning tray cover is upward and the cleaning tray is cleaning upward, the limiting device limits the cleaning tray cover. The cleaning tray cover of this utility model can rotate relative to the connecting plate, that is, the cleaning tray cover can rotate relative to the casters. It can be used for cleaning floors and car chassis, with multiple functions. However, there is a problem that when the cleaning tray cover needs to be flipped for adjustment, each caster needs to be flipped relative to the other casters. This will cause multiple casters to be flipped relative to each other at different times when the cleaning tray cover is flipped, which will reduce the convenience of flipping and adjusting. Therefore, we propose a cleaning tray. Utility Model Content

[0024] In this embodiment, the universal wheel synchronous flipping mechanism 6 further includes an external gear ring 61, which is disposed on the outside of the cleaning disc cover 1. The outer end of the external gear ring 61 is meshed with a plurality of first gears 63 distributed in a circle. The lower end of each first gear 63 is fixedly mounted with a first rotating shaft 64. The outer end of the first rotating shaft 64 is rotatably connected to a second L-shaped plate 610 through a bearing. The cleaning disc cover 1 is fixedly mounted on the end of the second L-shaped plate 610 near the cleaning disc cover 1. A first bevel gear 65 is fixedly mounted on the lower end of the first rotating shaft 64. The first bevel gear 65 is meshed with a second bevel gear 66.

[0025] Specifically, the external gear ring 61 drives the first gear 63 to rotate, which in turn drives the first shaft 64 to rotate. The first shaft 64 then drives the first bevel gear 65 to rotate, which in turn drives the second bevel gear 66 to rotate. The second bevel gear 66 then drives the second shaft 67 to rotate, which in turn drives the first L-shaped plate 68 to rotate. The first L-shaped plate 68 then drives the locking caster wheel 69 to flip over.
[0026] In this embodiment, the gear limiting mechanism 7 includes a third L-shaped plate 71. The cleaning disc cover 1 is fixedly installed at one end of the third L-shaped plate 71 near the cleaning disc cover 1.

A guide post 79 is fixedly installed at one end of the movable L-shaped plate 76 near the spring 75.
[0027] Specifically, the gear limiting mechanism 7 can first perform a direct work action on the moving L-shaped plate 76 by operating the handle 78. At this time, the handle 78 drives the moving L-shaped plate 76 to move, which in turn drives the C-shaped clamping plate 77 away from the second gear 73. At this time, the moving L-shaped plate 76 drives the guide post 79 to move, and the spring 75 is stretched. Next, the third rotating shaft 72 can be directly rotated by rotating the handle 74. At this time, the third rotating shaft 72 drives the second gear 73 to rotate.
[0028] In this embodiment, the surface of the cleaning disc cover 1 is provided with a plurality of circumferentially distributed water leakage grooves 8, and a water inlet column 2 is installed through the middle of the upper end of the cleaning disc cover 1. The upper end of the water inlet column 2 is rotatably connected to a cleaning pipe 3 through a bearing, and two centrally symmetrically arranged nozzles 4 are fixedly connected to the upper side of the outer end of the cleaning pipe 3.
[0029] Specifically, the water entering the water inlet column 2 generates a force on the cleaning pipe 3, causing the cleaning pipe 3 to rotate, which in turn drives the two nozzles 4 to rotate.
[0030] In this embodiment, a plurality of circumferentially distributed sliders 62 are fixedly installed on the inner wall of the outer gear ring 61, and each slider 62 has a sliding connection ring groove 5 at its outer end.
[0031] Specifically, the external gear ring 61 drives the slider 62 to rotate, and the slider 62 slides within the annular groove 5.
[0032] In this embodiment, the outer end of the second rotating shaft 67 is rotatably connected to the second L-shaped plate 610 through a bearing, and the second rotating shaft 67 passes through the second L-shaped plate 610.
[0033] Specifically, it is ensured that the second rotating shaft 67 does not interfere with the second L-shaped plate 610 during rotation.
[0034] In this embodiment, the outer end of the guide post 79 is slidably connected to the third L-shaped plate 71, and the guide post 79 passes through the third L-shaped plate 71.
[0035] Specifically, ensure that the guide post 79 does not interfere with the third L-shaped plate 71 during the sliding process.
[0036] In this embodiment, a limiting circular plate 710 is fixedly installed on the end of the guide post 79 away from the spring 75, and the limiting circular plate 710 is disposed inside the movable L-shaped plate 76.
[0037] Specifically, the guide post 79 can be limited in its movement distance by means of the limiting circular plate 710.
[0038] In this embodiment, an operating handle 78 is fixedly installed on the end of the movable L-shaped plate 76 away from the spring 75, and a rotating handle 74 is fixedly installed on the upper end of the third rotating shaft 72.
[0039] Specifically, the work can be performed directly on the moving L-shaped plate 76 by operating handle 78, and the work can be performed directly on the third rotating shaft 72 by rotating handle 74.
[0040] Working principle: First, the operating handle 78 directly moves the L-shaped plate 76. This moves the L-shaped plate 76, causing the C-shaped locking plate 77 to move away from the second gear 73. The L-shaped plate 76 then moves the guide post 79, stretching the spring 75. Next, the handle 74 rotates the third shaft 72, causing it to rotate. This rotates the second gear 73, which in turn rotates the external gear ring 61. The external gear ring 61 then rotates the first gear 63, which in turn rotates the first shaft 64. The first shaft 64 then rotates the first bevel gear 65, which in turn rotates the second bevel gear 66. The second bevel gear 66 then rotates the second shaft 67, which in turn rotates the first L-shaped plate 68. The first L-shaped plate 68 then rotates the locking caster wheel 69.
