Description

Technical Field

[0001] This utility model relates to the field of nursing bed technology, and in particular to a novel nursing bed with a bed surface that can be stably raised and lowered. Background Technology

[0002] With the increasing demand for medical care, nursing beds have gradually become an indispensable and important facility in hospitals, nursing homes, and home care. As a special bed designed specifically for patients or the elderly, it is mainly used to provide comfortable and convenient nursing services.

[0003] Traditional nursing beds, designed for ease of use by patients or the elderly, typically feature a lifting mechanism, usually achieved through a crank, gear, and rope system. During operation, caregivers adjust the bed's height or angle by rotating a handle or pulling a rope. However, in practice, this involves considerable physical exertion by caregivers. While the structure is simple and inexpensive, the bed adjustment is slow, and stability during lifting is poor. Therefore, a novel nursing bed with a stable lifting surface is proposed to address these issues. Utility Model Content

[0034] 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.

[0035] Reference Figures 1-5This utility model provides an embodiment of a novel nursing bed with a stable lifting surface, comprising a base frame 1. Two crossbars 4 are fixedly connected to the middle of the base frame 1. One crossbar 4 has a diagonal brace 3 rotatably connected to its top, and the other crossbar 4 has a slide rail 10 fixedly connected to its top. A pulley 18 is slidably connected to the middle of the slide rail 10, and a diagonal brace 17 is rotatably connected to the outer side of the pulley 18. A round rod 9 is fixedly connected to the other end of both the diagonal brace 17 and the diagonal brace 3. A support frame 11 is fixedly connected to the outer side of both the diagonal brace 3 and the diagonal brace 17. A support rod 19 is fixedly connected to the top of the support frame 11. Multiple bed frames 20 are fixedly connected to the top. A drive assembly is installed in the middle of the support rod 19. Connecting assemblies are installed on the outer sides of the multiple bed frames 20. A second bed frame 27 is installed at the other end of one of the connecting assemblies. Metal bed surfaces 6 are installed on the outer sides of the multiple bed frames 20 and the second bed frame 27. The drive assembly includes a connecting rod 12, which is fixedly connected to the middle of the support rod 19. Electric push rods 13 are fixedly connected to the left and right sides of the connecting rod 12. A connecting block 14 is rotatably connected to the output end of the electric push rod 13. The connecting block 14 is fixedly connected to the outer periphery of the round rod 9. The support frame 11 is trapezoidal in shape. First, supported by connecting rod 12, one of the electric push rods 13 is driven to push the connecting block 14. The rotation of the electric push rod 13 allows it to adjust its angle and push the round rod 9 through the connecting block 14. As the round rod 9 moves, it also moves the diagonal brace 17, allowing the diagonal brace 17 to drive the pulley 18 to slide in the middle of the slide rail 10. The top of the diagonal brace 17 moves up and down as it moves, allowing it to drive the support rod 19 up and down via the support frame 11. This adjusts the height of the bed frame 20 and the bed frame 27. Simultaneously, the support rod 19 moves... This causes the other support frame 11 to move together, while the support frame 11 drives the diagonal brace 3 to rotate at the top of the crossbar 4. This ensures the stability of the support rod 19 during vertical movement with the help of the diagonal brace 3, thereby reducing manual operation and ensuring stable lifting. When the nursing bed is in a stable state, another electric push rod 13 drives the connecting block 14, which in turn drives the diagonal brace 3 to rotate at the top of the crossbar 4 via the round rod 9. This allows the support rod 19 to tilt left and right under the action of the electric push rod 13, thus adjusting the bed angle according to the patient's specific needs. This helps the patient maintain a more comfortable position during different treatments and nursing care.

[0036] Reference Figure 1 , Figure 4 and Figure 6The connecting assembly includes multiple hinge blocks 23, which are fixedly connected to the outer sides of the second bed frame 27 and the multiple first bed frames 20, respectively. A bolt 26 is slidably connected to the middle of two adjacent hinge blocks 23, and a nut 24 is threaded onto the outer periphery of the bolt 26. A groove 25 is formed in the middle of the metal bed surface 6, and the hinge block 23 is located in the middle of the groove 25. Through the action of the bolt 26 and the nut 24, the hinge block 23 can connect the second bed frame 27 and the multiple first bed frames 20 into a single unit. Simultaneously, the second bed frame 27 can rotate around the outer periphery of the bolt 26 via one of the hinge blocks 23.

[0037] Reference Figures 1-3 Multiple bed frames 20 and 27 are fixedly connected to a fixing rod 21 at their center. A top rod 22 is fixedly connected to the center of one of the fixing rods 21, and an electric push rod 16 is fixedly connected to the bottom of the top rod 22. A frame 15 is fixedly connected to the center of a support rod 19. The output end of the electric push rod 16 is rotatably connected to the outside of the frame 15. Driven by the frame 15, one of the electric push rods 16 extends, and its other end pushes the top rod 22. This allows the top rod 22 to rotate the bed frame 27 via the fixing rod 21. This reduces the number of connecting structures, improves the stability when the patient sits up, increases the load-bearing capacity of the bed frame 27, and enhances the support strength of the metal bed surface 6 under the action of the fixing rod 21.

[0038] Reference Figure 1 , Figure 4 and Figure 7 Both the inner sides of bed frame 1 (20) and bed frame 2 (27) are fixedly connected to connecting seats 28. The outer side of connecting seats 28 is fixedly connected to protrusions 29. A rotating rod 30 is rotatably connected to the middle of protrusions 29. A connecting frame 5 is fixedly connected to the outer periphery of rotating rod 30. A guard plate 1 (7) is installed at the other end of connecting frame 5. A ratchet 32 ​​is fixedly connected to the outer periphery of rotating rod 30. A pawl 31 is rotatably connected to the outer side of protrusions 29. A spring plate 33 is installed on the outer side of protrusions 29. The spring plate 33 contacts the pawl 31. The pawl 31 engages with the ratchet 32. A guard plate 2 (8) is fixedly connected to the outer side of support rod 19. By pressing the pawl 31 to separate from the ratchet 32, the rotating rod 30 is no longer locked, allowing the guard plate 7 to rotate. This causes the guard plate 7 to rotate via the connecting frame 5, thus lowering the guard plate 7 so that patients or elderly people can lie down on the nursing bed. Simultaneously, rotating the guard plate 7 in the opposite direction will cause the rotating rod 30 to rotate the ratchet 32. Since the teeth of the ratchet 32 ​​are in the same direction as the ratchet 32's inclination, the ratchet 32 ​​will not be obstructed. At the same time, under the action of the spring plate 33, the pawl 31 can be pushed to engage with the ratchet 32, so that the pawl 31 locks the ratchet 32, thereby preventing the guard plate 7 from automatically flipping over after being erected, thus ensuring the protective effect of the guard plate 7 on the nursing bed.

[0039] Reference Figures 1-3 The base frame 1 is equipped with casters 2 on its outer side. The casters 2 facilitate the movement of the nursing bed.

[0040] Reference Figure 1 and Figure 4 The metal bed surface 6 has multiple ventilation holes in the middle. These ventilation holes improve the breathability of the nursing bed, preventing patients or elderly people from feeling uncomfortable due to moisture and stuffiness when lying flat for a long time.

[0041] Working principle: During use, one of the electric push rods 13 is driven to push the connecting block 14, which in turn moves the round rod 9. At the same time, the round rod 9 drives the pulley 18 to slide in the middle of the slide rail 10 through the diagonal brace 17. As the round rod 9 moves, it drives the support frame 11 to move, so that the support frame 11 can drive the support rod 19 to move up and down. At the same time, the other side of the support rod 19 will drive the other support frame 11 to move synchronously. Under the rotation of the diagonal brace 3 and the crossbar 4, the support rod 19 can be adjusted while moving up and down, ensuring the stability of the support rod 19 during movement. This reduces manual operation and ensures a stable lifting effect.

[0042] Supported by the frame 15, the electric push rod 16 is driven so that while the output end of the electric push rod 16 extends, the other end of the electric push rod 16 can push the top rod 22. The top rod 22 pushes the bed frame 27, so that the bed frame 27 can rotate and rise under the action of the hinge block 23. This reduces the number of connecting structures, improves the stability when the patient gets up, and makes the bed frame 27 have a greater load-bearing capacity.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
