[0025] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0026] Embodiment

[0027] Please refer to Figures 1-5, the present utility model provides a technical solution: a base structure for a vacuum device that is convenient to move. The base structure for a vacuum device that is convenient to move includes a bottom plate 1. An anti-slip pad 12 is fixedly installed on the top surface of the bottom plate 1. The anti-slip pads 12 are evenly distributed on the top surface of the bottom plate 1, which can increase the friction between the vacuum device and the bottom plate 1 and prevent the vacuum device from sliding on the top surface of the bottom plate 1. A positioning groove 2 is formed on the top surface of the bottom plate 1. A positioning pin 3 is inserted into the interior of the positioning groove 2. The positioning pin 3 is inserted into the bottom surface of a clamping plate 6. The clamping plate 6 and the bottom plate 1 are fixedly connected through the positioning pin 3, which facilitates the disassembly of the clamping plate 6. A tension spring 4 is sleeved on the surface of the positioning pin 3. One end of the tension spring 4 is fixedly connected to the inner wall of the positioning groove 2, and the other end of the tension spring 4 is fixedly connected to the surface of a pull plate 5, which facilitates the automatic reset of the positioning pin 3 when the tension spring 4 restores, thereby realizing the fixation of the clamping plate 6. A pull plate 5 is fixedly installed at one end of the positioning pin 3. A clamping plate 6 is inserted into the interior of the positioning groove 2. The number of the clamping plates 6 is two groups. The two groups of clamping plates 6 are symmetrically distributed on the top surface of the bottom plate 1. A clamping groove 7 is formed on the side surface of the clamping plate 6. A rubber gasket 13 is fixedly installed in the interior of the clamping groove 7. The rubber gaskets 13 are respectively located on the top surface and the bottom surface of the inner wall of the clamping groove 7, which can increase the friction between the clamping block 8 and the clamping groove 7, thereby fixing the clamping block 8 in the interior of the clamping groove 7. A clamping block 8 is slidably connected to the interior of the clamping groove 7. A clamping ring 9 is fixedly installed on the side surface of the clamping block 8. The shape of the clamping ring 9 is arc-shaped. The arc-shaped clamping ring 9 can fix a circular vacuum device. An anti-scratch protection layer is coated on the side surface of the clamping ring 9. The anti-scratch protection layer can provide protection for the surface of the vacuum device and prevent relatively serious scratches on the surface of the vacuum device. Universal wheels 10 are fixedly installed on the bottom surface of the bottom plate 1, and a push handle 11 is fixedly installed on the top surface of the bottom plate 1.

[0028] Working principle: When in use, manually push the push handle 11, and the push handle 11 can drive the bottom plate 1 to move. The bottom plate 1 then drives the universal wheels 10 on its bottom surface to move. At this time, the base and the vacuum device can be moved. When placing the vacuum device on the top surface of the bottom plate 1, manually pull the pull plate 5. The pull plate 5 drives the positioning pin 3 to move. Then insert the clamping plate 6 into the positioning groove 2. Subsequently, release the hand pulling the pull plate 5. At this time, the tension spring 4 loses the external force restriction. Due to its own pulling force, the tension spring 4 drives the pull plate 5 to move. The pull plate 5 then drives the positioning pin 3 to move into the interior of the clamping plate 6 until the positioning pin 3 is inserted into the interior of the clamping plate 6. At this time, the clamping plate 6 can be fixed on the top surface of the bottom plate 1 and provide a fixing effect on the vacuum device. When the vacuum device is circular, take the clamping block 8, make the clamping block 8 opposite to the clamping groove 7, and snap the clamping block 8 into the interior of the clamping groove 7. Since the rubber gasket 13 is closely attached to the surface of the clamping block 8, it is necessary to slide the clamping block 8 forcefully. The clamping block 8 then slides in the interior of the clamping groove 7 until the clamping block 8 is fixed in a suitable position. At this time, the clamping ring 9 is also fixed, and then the circular vacuum device can be fixed.

[0029] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the protection scope of the technical solution of the present utility model.
