DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 - Figure 3 The utility model provides a technical solution: a hood-detachable polishing machine, comprising a polishing machine base 1, a main cover 2 arranged at the end of the polishing machine base 1, and a grinding disc 3 arranged on the front of the main cover 2, a driving component 6 that can rotate forward and backward is arranged on the back of the main cover 2, a second folding cover component 5 that can rotate on the inner side of the main cover 2 is arranged on the outer side of the driving component 6, and a first folding cover component 4 that rotates opposite to the second folding cover component 5 as the driving component 6 rotates is arranged on the outer side of the second folding cover component 5. When the polishing machine base 1 is not in use, the driving component 6 can be started to drive the first folding cover component 4 and the second folding cover component 5 to rotate synchronously and in the opposite direction to each other, so that the first cover disc 41 and the second cover disc 51 complete the rotation and closing work on the outer side of the grinding disc 3. Through this design, it can be avoided that the edge of the grinding disc 3 of the polishing machine base 1 is in contact with the outside during the non-use stage, especially during transportation, thereby preventing damage.

[0029] See also Figure 4 - Figure 7 The driving assembly 6 includes a forward and reverse motor 61, which is fixedly installed on the back of the main cover 2. The output end of the forward and reverse motor 61 is fixedly connected to a rotating shaft 62, and the end of the rotating shaft 62 is fixedly connected to a first gear disk 63. The inner sleeve 52 is fixedly connected to the outside of the first gear disk 63, and the outside of the inner sleeve 52 is fixedly connected to the second cover disk 51. The second cover disk 51 is located on the outside of the grinding disk 3 in the main cover 2. Through this design, the inner sleeve 52 and the second cover disk 51 can rotate on the inside of the main cover 2.

[0030] See also Figure 4 - Figure 7The driving assembly 6 also includes a second toothed disc 64, which is arranged in parallel with the first toothed disc 63. The first toothed disc 63 and the second toothed disc 64 are meshed and connected through a linkage assembly 65. The linkage assembly 65 includes a connecting rod 651, one side of the connecting rod 651 is fixedly connected to 632, and the other side of the connecting rod 651 is fixedly connected to a second toothed column 653. One side of the first toothed column 652 is meshed and connected with the first toothed disc 63, and the other side of the first toothed column 652 is meshed and connected with the second toothed disc 64. One side of the second toothed column 653 is meshed and connected with the first toothed disc 63. The toothed disc 63 is meshed and connected, and the other side of the second tooth column 653 is meshed and connected with the second toothed disc 64. The first folding cover assembly 4 includes an outer sleeve 42, and the inner side of the outer sleeve 42 is fixedly connected to the second toothed disc 64. The first folding cover assembly 4 also includes a first cover disc 41, and the first cover disc 41 is fixedly connected to the outer side of the outer sleeve 42. The first cover disc 41 is located on the outer side of the grinding disc 3 in the main cover 2. Through this design, the first cover disc 41 and the outer sleeve 42 can complete the rotation in the opposite direction to the second cover disc 51 under the drive of the forward and reverse motor 61.

[0031] The working principle and use process of the utility model are as follows: when the polishing machine base 1 is not in use, the forward and reverse motor 61 can be used to drive the rotating shaft 62 to rotate. At this time, the first toothed disc 63 located at the end of the rotating shaft 62 will synchronously drive the inner sleeve 52 and the second cover disc 51 to rotate, thereby completing the unilateral closing of the grinding disc 3. At the same time, when the first toothed disc 63 rotates, the first tooth column 652 and the second tooth column 653 engaged on one side of the first toothed disc 63 will rotate synchronously and drive the second toothed disc 64 engaged on one side thereof to rotate. At this time, the outer sleeve 42 and the first cover disc 41 fixedly connected to the outer side of the second toothed disc 64 will synchronously rotate in the opposite direction to the second cover disc 51, thereby completing the closing work on the other side of the grinding disc 3. This design can prevent the polishing machine base 1 from contacting the edge of the grinding disc 3 with the outside during the non-use stage, especially during transportation, thereby causing damage.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
