[0029] like Figures 1 to 9 As shown, the first aspect of this utility model provides a correction device, comprising: a support frame 1, wherein connecting seats 2 are provided at the top left and right ends of the support frame 1, the connecting seats 2 are provided with sliding grooves 21, the two connecting seats 2 are arranged opposite to each other so that the two sliding grooves 21 are arranged facing each other, a correction frame 3 that can rotate relative to the support frame 1 is connected to the support frame 1, the two ends of the correction frame 3 are located in the sliding grooves 21, the correction device further comprises a connecting plate 4, a driving member 5 is provided on the connecting plate 4, the output shaft 51 of the driving member 5 is rotatably connected to the correction frame 3, and a guiding component 6 that can guide the output shaft 51 to slide is provided between the output shaft 51 of the driving member 5 and the connecting plate 4.

[0030] In use, this invention is mounted on existing equipment such as a bed frame via the support frame 1. When changing the sheets, the straightening frame 3 changes its angle relative to the support frame 1 according to the drive component 5, preventing the sheets from shifting or gathering towards the center during movement, thus avoiding wrinkles. The guide component 6 facilitates the sliding of the output shaft 51 relative to the connecting plate 4, thereby guiding the range of rotation of the straightening frame 3 relative to the support frame 1. Simultaneously, both ends of the straightening frame 3 are confined within the grooves 21 of the two connecting seats 2, forming a support and reducing the swaying of the straightening frame 3.

[0031] The alignment frame 3 includes a swing plate 31, which is hinged to the support frame 1. A horizontally arranged alignment rod 32 is connected to the top of the swing plate 31, and the end of the alignment rod 32 can extend into the slide groove 21. The swing plate 31 rotates around the support frame 1 via the hinge point, and the alignment rod 32 acts as an extension arm, its end sliding within the slide groove 21 for more precise adjustment. The swing plate 31 is connected to the support frame 1 by screws 11, and the swing plate 31 can rotate relative to the screws 11.

[0032] The end of the correction rod 32 is also connected to a rotating shaft 33 that extends into the slide groove 21. A rotating wheel 34 that rotates with the shaft 33 is connected to the shaft 33. The surface of the rotating wheel 34 can contact the groove wall of the slide groove 21 and move along the groove wall. The rotating wheel 34 allows the rotating wheel 34 to slide along the groove wall of the slide groove 21, reducing friction and preventing jamming, thus ensuring smoother adjustment.

[0033] The lower end of the swing plate 31 is connected to an extension plate 311 that faces and extends into the support frame 1. The end of the extension plate 311 is connected to a connecting arm 312 that extends toward the drive member 5. The projections of the extension plate 311 and the connecting arm 312 on the horizontal plane form an L-shape. The end of the output shaft 51 is rotatably connected to the connecting arm 312. The arrangement of the extension plate 311 and the connecting arm 312 allows the connection point of the output shaft 51 of the drive member 5 to be located within the internal space of the support frame 1, resulting in a more compact overall structure. The output shaft 51 of the drive member 5 rotates relative to the support frame 1 through the transmission of the connecting arm 312 and the extension plate 311.

[0034] The connecting arm 312 is provided with a vertically oriented adjustment hole 3121, and the output shaft 51 is provided with a slot 511 for the connecting arm 312 to be inserted. The output shaft 51 is also provided with a screw assembly 52 through which the output shaft 51 and the connecting arm 312 are sequentially inserted. The design of the slot 511 allows the connecting arm 312 to be quickly and easily inserted into the output shaft 51 for initial positioning. The cooperation between the vertically oriented adjustment hole 3121 and the slot 511 facilitates the installation of the connecting arm 312 and the output shaft 51, making adjustment convenient during installation.

[0035] The correction rod 32 is also provided with a groove 321, and a mounting plate 322 is provided in the groove 321. A correction sensor 323 is connected to the mounting plate 322. The correction rod 32 is also provided with an outer cover 324 that can close and seal the groove 321.

[0036] The guiding component 6 includes connecting blocks 61 disposed on the connecting plate 4, each connecting block 61 being provided with a guiding groove 62, and the output shaft 51 being provided with a guiding plate 63 capable of extending into the guiding groove 62. The guiding groove 62 provides movement space for the guiding plate 63, and the upper and lower walls of the guiding groove 62 can limit the rotation range of the guiding plate 63, thereby limiting the rotation range of the swing plate 31.

[0037] The connecting seat 2 includes a base plate 22, on which a vertical support plate 23 is provided, and on which the sliding groove 21 is provided. The connecting seat 2 is an integrally formed structure.

[0038] The base plate 22 is also provided with a support assembly 7 that can slide along the slide groove 21 to support the end of the alignment frame 3. The support assembly 7 includes a through hole 71 connected to the base plate 22, and a sliding rod 72 that can move relative to the through hole 71. A support platform 73 is provided on the top of the sliding rod 72, and a first spring 74 is provided between the lower end of the support platform 73 and the sliding rod 72. A nut is connected to the lower end of the sliding rod 72, and the nut is located below the base plate 22. The support platform 73 provides uniform support force through multiple first springs 74, so that its upper surface can adaptively conform to the rotating wheel 34 of the alignment frame 3, thereby buffering and preventing the alignment frame 3 from rotating too much. By adjusting the position of the nut, the sliding rod 72 can be adjusted according to the position of the rotating wheel 34 of the alignment frame 3, so as to improve the buffering effect.

[0039] The second aspect of this utility model provides a nursing bed, including a bed body 8, one end of which is connected to the aforementioned corrective device 900. In use, the support frame 1 is installed onto the bed body 8 by screws or snap-fit ​​connections. When changing the bed sheet, the corrective frame 3 changes its angle relative to the support frame 1 according to the drive of the drive component 5, preventing the bed sheet from shifting or converging towards the center during movement, thus avoiding wrinkles. The guide component 6 facilitates the sliding of the output shaft 51 relative to the connecting plate 4, thereby guiding the range of rotation of the corrective frame 3 relative to the support frame 1. Simultaneously, both ends of the corrective frame 3 are confined within the grooves 21 of the two connecting seats 2, forming a support and reducing the swaying of the corrective frame 3. The bed body 8 also includes a bed sheet roller winding structure and a bed sheet roller placement structure, enabling the bed sheet to move.
