Description

Technical Field

[0001] This utility model relates to the field of nursing bed technology, specifically to a linkage opening and closing mechanism between a folding bed board and a toilet seat of a nursing bed. Background Technology

[0002] Nursing beds are medical care devices designed specifically for people with limited mobility, such as disabled / semi-disabled elderly, postoperative patients, and those recovering from serious illnesses. Their core purpose is to replace users' independent actions (such as getting up, turning over, and moving) through mechanical or electric structures, while reducing the burden on caregivers, balancing functionality and comfort, and helping users complete basic daily activities while in bed.

[0003] However, the existing nursing beds have separate drive systems for the folding bed board and the toilet seat, requiring a step-by-step operation of "folding the bed board first, then unfolding the toilet seat." This requires caregivers to operate two drive systems, which prolongs the waiting time for users from preparing to use the toilet to completing the posture adjustment. This is especially true for users with extremely limited mobility who need a quick response (such as incontinent patients or those with limited mobility after surgery). The step-by-step operation can easily aggravate physical discomfort or delay care, resulting in poor convenience. Utility Model Content

[0004] This utility model provides a linkage opening and closing mechanism between the folding bed board and the toilet seat of a nursing bed to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model discloses a linkage opening and closing mechanism for a folding bed board and a toilet seat of a nursing bed, including a mounting plate, a toilet installed through the mounting plate, a seat installed on the toilet, a horizontal toilet seat provided on the toilet, a folding bed board movably installed on the seat, a driving block installed on the mounting plate, a folding rod movably installed on the driving block, the other end of the folding rod movably installed on the folding bed board, a push rod installed on the driving block, and an opening and closing component installed on the push rod, the opening and closing component being connected to the horizontal toilet seat.

[0018] 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 scope of protection of the present utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Example 1: This embodiment of the present invention provides a linkage opening and closing mechanism between the folding bed board of a nursing bed and the toilet seat, such as... Figures 1-3 As shown, the device includes a mounting plate 7, a toilet 8 is mounted through the mounting plate 7, a seat 6 is mounted on the toilet 8, a horizontal toilet seat 15 is provided on the toilet 8, a folding bed board 3 is movably mounted on the seat 6, a drive block 11 is mounted on the mounting plate 7, a folding rod 2 is movably mounted on the drive block 11, the other end of the folding rod 2 is movably mounted on the folding bed board 3, a push rod 9 is also mounted on the drive block 11, and an opening and closing assembly is mounted on the push rod 9, the opening and closing assembly is connected to the horizontal toilet seat 15.

[0022] The working principle and beneficial effects of the above technical solution are as follows: When the drive block 11 moves, it transmits power through the folding rod 2 connected to it. The folding rod 2 pushes / pulls the folding bed board 3 movably installed on the seat cushion 6, so that the folding bed board 3 unfolds or retracts around the movable connection point, realizing the folding and resetting of the bed board. At the same time as the drive block 11 moves, the push rod 9 installed on it moves synchronously. The push rod 9 drives the opening and closing component on it to operate. The opening and closing component transmits power to the horizontal toilet seat 15, and finally drives the horizontal toilet seat 15 to complete the opening or closing action.

[0023] The movement of the drive block 11 simultaneously drives the folding bed board 3 to fold via the folding rod 2, and also drives the push rod 9 and the opening / closing assembly to operate, thereby opening and closing the toilet seat 15. In other words, the movement of this core component, the drive block 11, achieves both the "folding bed board" and "toilet seat opening / closing" functions simultaneously, eliminating the need to control two separate drive systems. This significantly reduces the number of steps required, greatly shortening the overall time from preparing to use the toilet to adjusting the posture, effectively avoiding discomfort caused by operational delays, and enhancing practicality and convenience.

[0024] Example 2: Based on Example 1 above, as follows Figures 1-2 As shown, a drive source 1 is fixedly installed on the mounting plate 7. A threaded rod 12 is fixedly connected to the output end of the drive source 1. A fixing block 10 is rotatably connected to the other end of the threaded rod 12. A drive block 11 is threadedly connected to the threaded rod 12.

[0025] Preferably, the front and rear sides of the drive block 11 are rotatably connected to folding rods 2, and the other end of the folding rods 2 is rotatably connected to the folding bed board 3.

[0026] The working principle and beneficial effects of the above technical solution are as follows: The output end of the drive source 1 drives the threaded rod 12 to rotate. Since the threaded rod 12 is threadedly connected to the drive block 11 and the other end is limited by the fixed block 10, the rotational motion of the threaded rod 12 is converted into the linear movement of the drive block 11 along the axial direction of the threaded rod 12. When the drive block 11 moves, the folding rod 2 rotatably connected to its front and rear sides pushes and pulls the folding bed board 3. By utilizing the rotational connection between the folding rod 2 and the folding bed board 3, the linear motion of the drive block 11 is converted into the folding action of the folding bed board 3.

[0027] The transmission combination of "drive source 1-threaded rod 12-drive block 11" is adopted. The rotational motion is converted into linear motion through threaded connection, which makes the transmission more stable and the action deviation smaller. The entire linkage mechanism is driven by a single drive source 1, and there is no need to set up an independent power unit for the folding bed board 3 and the horizontal toilet seat 15, which makes it more practical.

[0028] Example 3: Based on Example 2 above, as follows Figures 1-3As shown, push rods 9 are symmetrically fixed on the drive block 11. The push rods 9 are L-shaped and have a toothed plate on their upper surface.

[0029] Preferably, armrests 13 are provided on both the front and rear sides of the seat cushion 6, and the armrests 13 are fixedly mounted on the mounting plate 7.

[0030] Preferably, the opening and closing assembly includes a connecting rod 17 arranged at the front and rear, one end of the connecting rod 17 is connected to the handrail 13, the other end of the connecting rod 17 is connected to the toilet 8, and a gear 5 is rotatably arranged on the connecting rod 17, with a gear plate meshing with the gear 5.

[0031] Preferably, the mounting plate 7 has symmetrically arranged sliding grooves 16, and a stabilizing rod 18 is slidably arranged in the sliding groove 16. The same U-shaped plate 4 is fixed on the two stabilizing rods 18, and a toothed plate 2 is symmetrically arranged on the U-shaped plate 4. The toothed plate 2 is meshed with the gear 5.

[0032] Preferably, a connecting plate is fixedly installed on the U-shaped plate 4, and the connecting plate is fixedly connected to the horizontal toilet seat 15.

[0033] The working principle and beneficial effects of the above technical solution are as follows: When the drive block 11 moves, it drives the L-shaped push rod 9 to move. The toothed plate 1 on the push rod 9 drives the gear 5 that meshes with it to rotate. The gear 5 drives the toothed plate 2 on the U-shaped plate 4 that meshes with it, so that the U-shaped plate 4 slides linearly along the slide groove 16 of the mounting plate 7 through the bottom stabilizing rod 18. The U-shaped plate 4 drives the horizontal toilet seat 15 to complete the opening and closing action.

[0034] Through the meshing transmission structure of "tooth plate one - gear 5 - tooth plate two", the linear motion of the push rod 9 is converted into the opening and closing action of the horizontal toilet seat 15. The high degree of matching ensures that the folding bed board 3 and the horizontal toilet seat 15 are matched, and the opening and closing process is smooth and controllable, with stronger stability.

[0035] Example 4: Based on Example 3 above, as follows Figure 1 and Figure 3 As shown, the height of the stabilizer bar 18 is greater than the height of the fixing block 10.

[0036] Preferably, the seat cushion 6 has a through groove 14 that is connected to the toilet 8.

[0037] The working principle and beneficial effects of the above technical solution are as follows: the stabilizer bar 18 and the fixed block 10 are at different height levels, and the two do not overlap in their respective motion trajectories, ensuring that the U-shaped plate 4 is not obstructed by the fixed block 10 when it drives the horizontal toilet seat 15 to open and close. The through-channel 14 forms a continuous passage from the surface of the seat cushion 6 to the inside of the toilet 8. When the folding bed board 3 is folded and the horizontal toilet seat 15 is opened, the user can directly use the toilet through the through-channel 14 without having to adjust their body position. This reduces physical restraint and discomfort during toileting, lowers the risk of waste leakage, and results in higher cleanliness.

[0038] 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.
