[0025] Embodiment 1: An auxiliary replacement mechanism for a medical nursing bed sheet, as Figures 1 - 4As shown in the figure, it includes a supporting bed body 1, and a rotating support plate 2 fixedly arranged at the lower end of the supporting bed body 1. There are at least two rotating support plates 2. A rotating support column 3 is rotatably connected to the adjacent side of the two rotating support plates 2. At least two rotating guide rods 6 are rotatably arranged above the rotating support column 3. Receiving grooves 7 are formed on both corresponding sides of the supporting bed body 1. A height adjusting block 8 is slidably arranged inside the receiving groove 7. The upper end of the height adjusting block 8 is fixedly connected with a clamping connecting plate 11. There are at least two clamping connecting plates 11. A sliding support column 12 is inserted between the two clamping connecting plates 11. A telescopic spring 13 is fixedly connected inside the sliding support column 12. The upper end of the telescopic spring 13 is fixedly connected with a limiting cylinder 14. The limiting cylinder 14 is inserted into the sliding support column 12, and the upper half of the sliding support column 12 is located inside the limiting cylinder 14. A number of clamping teeth 16 are fixedly connected to the adjacent side of the two clamping connecting plates 11. The clamping teeth 16 are located at one end of the clamping connecting plate 11 away from the sliding support column 12. When the device operates, under the rotational support of the two rotating support plates 2 under the supporting bed body 1 for the rotating support column 3, the bed sheet wrapped around the outside of the rotating support column 3 rotates. Then, under the rotational guidance of the rotating guide rod 6, it moves upward above the supporting bed body 1. Subsequently, under the clamping and limiting of the clamping teeth 16 between the two clamping connecting plates 11, the bed sheet is pulled to ensure the accuracy of the angle during its movement and improve the stability when the bed sheet is laid flat. At the same time, by pulling the limiting cylinder 14 upward, the telescopic spring 13 can be driven to stretch inside the sliding support column 12, thereby moving the height between the two clamping connecting plates 11. Then, under the reset contraction of the telescopic spring 13, the limiting cylinder 14 is driven to move back to the sliding support column 12. Thus, under the contraction of the telescopic spring 13, the effect of tightly limiting the two clamping connecting plates 11 is achieved, so as to ensure the stability when one side of the clamping teeth 16 clamps the bed sheet. And under the elastic support of the telescopic spring 13, it is ensured that the clamping of the clamping teeth 16 can ensure the normal movement of the bed sheet. And through the sliding support of the receiving groove 7 for the height adjusting block 8 and the clamping connecting plate 11, the movement during use and the receiving support during placement can be carried out, improving the reasonable placement space of the device and effectively saving the use space of the device.
[0026] As Figures 1 - 4As shown, one side of the inner wall of the storage groove 7 is rotatably connected to a rotating support bolt 9. The rotating support bolt 9 is threadedly engaged with the height adjustment block 8. The rotating support bolt 9 extends to one side of the height adjustment block 8. One end of the rotating support bolt 9 is threadedly engaged with a rotating fastening cap 10. The rotating fastening cap 10 is used for fastening the height adjustment block 8. Under the threaded support of the rotating support bolt 9, the effect of moving the position of the height adjustment block 8 inside the storage groove 7 is achieved. And by rotating and fastening the rotating fastening cap 10, the effect of limiting the position of the height adjustment block 8 is achieved. At the same time, through the groove opened at the connection between the height adjustment block 8 and the rotating support bolt 9, it is ensured that the height adjustment block 8 can move a certain height under the limit of the rotating support bolt 9, thereby improving the effect of the height adjustment block 8 driving the upper components to be moved out for use.
[0027] As Figures 1 - 4 shown, a limit bolt 15 is inserted into the upper end of the clamping connecting plate 11. The limit bolt 15 extends out of the lower end of the clamping connecting plate 11. The limit bolt 15 is threadedly engaged with the lower clamping connecting plate 11. The limit bolt 15 is used to limit the distance between the two clamping connecting plates 11. By rotating and adjusting the length of the limit bolt 15 according to the thickness of the bed sheet clamped by the two clamping connecting plates 11, the moving distance between the two clamping connecting plates 11 is restricted, ensuring the stability when the two clamping connecting plates 11 are pulled and adjusted and used for clamping.
[0028] Embodiment 2: A medical care bed sheet auxiliary replacement mechanism, as Figures 1 - 4 shown, the clamping connecting plate 11 is slidably connected to the storage groove 7. The storage groove 7 is used for storing the height adjustment block 8 and the clamping connecting plate 11. Under the support of the storage groove 7 and by moving the height adjustment block 8 and the clamping connecting plate 11, the height adjustment block 8 and the clamping connecting plate 11 can be stored and placed, so that when the clamping connecting plate 11 and the height adjustment block 8 are not in use, they can be retracted in time, further saving the use space of the device.
[0029] As Figures 1 - 4As shown in the figure, a rotating frame 4 is rotatably arranged above the rotating support plate 2. The rotating frame 4 is in threaded engagement with the support bed body 1 and extends into its interior. A rotating connection block 5 is fixedly connected to the outside of the rotating frame 4. The rotating connection block 5 is rotatably connected to the rotating guide rod 6 and extends to one side of it. Guide rails 17 are fixedly connected to the corresponding two sides of the support bed body 1. An leveling frame 18 is slidably connected to the two guide rails 17 at the same time. The leveling frame 18 is located outside the support bed body 1. Under the threaded support of the support bed body 1 for the rotating frame 4, the effect of firmly fixing the position during its rotation is achieved. And through the groove opened at the connection between the rotating connection block 5 and the support bed body 1, the rotating connection block 5 can be supported to perform stable angle adjustment under the rotating support of the rotating frame 4. At the same time, under the sliding support and limitation of the two guide rails 17 on the leveling frame 18, the effect of leveling the sheet on the support bed body 1 is achieved by leveling the leveling frame 18. By rotating the rotating frame 4 under the support of the support bed body 1, the rotating connection block 5 outside it can be rotated simultaneously, and then the position of the rotating guide rod 6 can be adjusted and rotated, so as to ensure the accurate position of the rotating guide rod 6 during guiding.
[0030] Working principle: Under the rotating support of the two rotating support plates 2 under the support bed body 1 for the rotating support column 3, the sheet wrapped outside the rotating support column 3 rotates. Then, under the rotating guidance of the rotating guide rod 6, it moves upward to the support bed body 1. Subsequently, under the clamping and limiting of the clamping teeth 16 between the two clamping connection plates 11, the sheet is pulled to ensure the accuracy of its angle during movement and improve the stability of the sheet during laying. At the same time, by pulling the limiting cylinder 14 upward, the telescopic spring 13 can be driven to stretch inside the sliding support column 12, so as to move the height between the two clamping connection plates 11. Then, under the reset contraction of the telescopic spring 13, the limiting cylinder 14 is driven to move back to the sliding support column 12. Thus, under the contraction of the telescopic spring 13, the effect of firmly limiting the two clamping connection plates 11 is achieved, so as to ensure the stability of one side of the clamping teeth 16 when clamping the sheet. And under the elastic support of the telescopic spring 13, it is ensured that the clamping of the clamping teeth 16 can ensure the normal movement of the sheet. And under the sliding support of the storage groove 7 for the height adjustment block 8 and the clamping connection plate 11, their movement during use and storage support during placement can be carried out, improving the reasonable placement space of the device and effectively saving the use space of the device.
[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
