Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1
[0030] This embodiment provides a cleaning cabinet, including as follows: Figures 1 to 4 The flip cover assembly shown includes a front cover 1, a rear cover 2, and a pivot cover 3. It also includes a limiting structure 4 for fixing the pivot cover 3 to the rear cover 2. The fixing structure can limit the pivot cover, so that the pivot cover is fixed to the rear cover and cannot rotate. This prevents the pivot cover from rotating with the front cover when it is flipped, and avoids the pivot cover from generating dust due to friction with the rear cover when rotating.
[0031] As a further embodiment of this utility model: the limiting structure 4 includes a through hole 43 opened on the rear cover 2 and cooperating with the rotating shaft 41, a rotating shaft 41 provided on the rotating shaft cover 3, one end of the rotating shaft 41 passing through the front cover 1 and the through hole 43 and having a connecting buckle block 42 for fixing the rotating shaft 41 on the rear cover 2, the limiting structure 4 also includes a limiting port 44 opened on the inner wall of the through hole 43 and cooperating with the rotating shaft cover 3 and restricting the rotating shaft cover 3 from rotating in the circumferential direction, the rear cover 2 is provided with a connecting shaft 21, the front cover 1 is provided with a connecting hole 11 cooperating with the connecting shaft 21, the limiting port 44 can limit the rotating shaft cover 3, prevent the front cover 1 from rotating with the rotating shaft cover 3 during the flipping process, avoid friction between the limiting structure 4 on the rotating shaft cover 3 and the rear cover 2, and the limiting structure 4 can fix the rotating shaft cover 3, after the rotating shaft cover 3 is fixed, it can prevent the front cover 1 from detaching from the connecting shaft 21 during the flipping process, and release the rotational connection with the rear cover 2.
[0032] Specifically: First, insert the rotating shaft 41 on the rotating shaft cover 3 into the through hole 43, so that the connecting buckle block 42 on the rotating shaft 41 passes through the limiting hole 44 and is locked onto the rear cover 2, so that the rotating shaft cover 3 is fixed on the rear cover 2. The cooperation between the limiting hole 44 and the connecting buckle block 42 prevents the rotating shaft cover 3 from rotating with the front cover 1, so that the rotating shaft cover 3 and the rear cover 2 will not rub against each other and generate dust.
[0033] As a further embodiment of this utility model: a wear-resistant ring 12 or a first wear-resistant sheet 13 is provided on the side of the front cover 1 near the rear cover 2 to prevent the front cover 1 and the rear cover 2 from contacting each other. A second wear-resistant sheet 14 is provided on the side of the front cover 1 near the pivot cover 3 to separate the front cover 1 and the pivot cover 3. The wear-resistant ring 12 is made of silicone, and the first wear-resistant sheet 13 and the second wear-resistant sheet 14 are both made of PVC. The wear-resistant ring 12 and the first wear-resistant sheet 13 prevent the front cover 1 from contacting the rear cover 2 when the front cover 1 and the rear cover 2 are rotated and connected. While separating the front cover 1 and the rear cover 2, the wear-resistant ring 12 can also play the role of a damping structure during the flipping process of the front cover 1, so that the flipping speed of the front cover 1 is not too fast. The second wear-resistant sheet 14 can prevent the front cover 1 and the pivot cover 3 from rubbing together and generating dust. In addition, the PVC material has good wear resistance and will not generate dust even after long-term contact with the front cover 1 or the rear cover 2.
[0034] Example 2
[0035] The difference between this embodiment and Embodiment 1 is that, as Figures 5 to 8 As shown, the limiting structure 4 also includes a rubber plug 45 located on one side of the rear cover 2 and interference-fitted with the through hole 43. One end of the rotating shaft 41 has a connecting opening 411 that interference-fits with the rubber plug 45. A limiting groove 451 is provided on the outer periphery of the rubber plug 45. The inner wall of the connecting opening 411 has a limiting rib 412 that limits and fits with the limiting groove 451. After the rotating shaft 41 is inserted into the through hole 43, the rubber plug 45, which matches the shape of the rotating shaft 41, is inserted into the through hole 43, so that the rubber plug 45 and the through hole 43 form an interference fit. At the same time, the rubber plug 45 After entering the through hole 43, the rubber plug 45 will enter the connecting opening 411 and form an interference fit with the connecting opening 411. In addition, the limiting rib 412 will also enter the limiting groove 451 to form an interference fit, increasing the friction coefficient between the rotating shaft 41 and the rubber plug 45. Because the friction coefficient between the rubber plug 45 and the inner wall of the through hole 43 is large, the rotating shaft 41 cannot drive the rubber plug 45 to rotate. This avoids the situation where the rotating shaft cover 3 rotates with the front cover 1 when the front cover 1 rotates, so that the rotating shaft cover 3 will not rub against the rear cover 2.
[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
