Description

Technical Field

[0001] This utility model belongs to the technical field of surgical auxiliary equipment, specifically a bed-raising assist device. Background Technology

[0002] Bed-raising assistive devices are generally used by the elderly, paralyzed patients, and other people with limited mobility to help them get up, lie down, feed themselves, or relax their muscles and bones. Some elderly people experience difficulty getting out of bed due to aging or illness, requiring assistance from family members or caregivers. While electric nursing beds are available that can raise the upper body for easier getting up, these beds have complex, integrated designs. When elderly people need to practice getting up independently, it can be difficult. Although some nursing beds have handles on both sides, these handles are located at the edge of the bed, a distance from the elderly person's body, making it difficult for them to exert force when pulling at an angle. Therefore, we propose a bed-raising assistive device. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bed-starting aid.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A bed-raising assist device includes a bed board, support columns, and a placement plate. The bed board and the placement plate are both supported by four support columns, and the placement plate is located directly below the bed board. The upper end of the bed board has a placement groove and two through grooves. A connecting column is fixedly installed on one end of the placement groove on the inner side of the bed board. A lifting plate is installed in the placement groove. One end of the lifting plate is rotatably connected to the connecting column, and the other end of the lifting plate can rotate freely.

[0006] A threaded rod is mounted on the upper end of a placement plate via two first mounting blocks. One end of the threaded rod is fixedly connected to the output shaft of a first drive motor. A movable block is threadedly connected to the side end of the threaded rod. A support rod is installed between the movable block and the lifting plate. The support rod and the movable block are rotatably connected via a connecting assembly. The lifting plate and the support rod are rotatably connected via a connecting assembly.

[0007] A rotating shaft is mounted on the upper end of the placement plate via two second mounting blocks. Two traction ropes are fixedly connected to the outside of the rotating shaft. The end of the traction rope away from the rotating shaft passes through a through groove on the bed plate and is located above the bed plate. A drive assembly for driving the rotating shaft to rotate is installed on the side end of the rotating shaft.

[0008] Furthermore, multiple slots are provided at the upper end of the bed board on both sides, and guardrails are installed on both sides of the upper end of the bed board, with the lower ends of the guardrails inserted into the slots.

[0009] Furthermore, the connecting assembly includes two connecting blocks and a connecting shaft, the connecting shaft being fixedly installed between the two connecting blocks, and the connecting shaft having a cylindrical structure.

[0010] Furthermore, the upper end of the placement plate is fixedly installed on both sides of the threaded rod, and the inner side of the two limiting plates is provided with limiting grooves. The two ends of the moving block are fixedly installed with limiting blocks, and the limiting blocks are adapted to the limiting grooves.

[0011] Furthermore, the drive assembly includes a second drive motor and a drive gear. The second drive motor is fixedly mounted on the upper end of the placement plate, the drive gear is fixedly mounted on the output shaft of the second drive motor, and a driven gear is fixedly mounted on the side end of the rotating shaft. The drive gear and the driven gear are meshed together.

[0012] Furthermore, a hand loop is fixedly installed at the end of the traction rope away from the rotating end, and an anti-slip layer is provided on the inner side of the hand loop.

[0013] Furthermore, the end of the connecting assembly connected to the bed board is away from the connecting post, and the moving block is located on the side close to the connecting post.

[0014] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0015] Fixed connection: refers to a connection in which parts or components are fixed in place and there is no relative movement. It is divided into two types: detachable connection and non-detachable connection.

[0016] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0017] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0018] The beneficial effects of this invention are as follows: When the device is in use, the elderly person grasps the pull ring, and then the first drive motor and the second drive motor are started simultaneously. After the first drive motor starts, it drives the threaded rod to rotate, thereby driving the moving block to move closer to the first drive motor. This causes the lifting plate to be raised in an inclined position through the support rod. At the same time, after the second drive motor starts, it drives the driving gear to rotate, thereby driving the driven gear to rotate, which in turn drives the rotating shaft to rotate, thereby causing the traction rope to wind up. The combined effect of the lifting plate rising in an inclined position and the winding of the traction rope pulls the elderly person up, thus helping them get out of bed.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] A type of bed-starting aid, such as Figures 1-5 As shown, the device includes a bed board 1, support columns 2, and a placement board 3. Both the bed board 1 and the placement board 3 are supported by four support columns 2. The placement board 3 is located directly below the bed board 1. The upper end of the bed board 1 has a placement groove 4 and two through grooves 5. A connecting column 6 is fixedly installed on one end of the placement groove 4 on the inner side of the bed board 1. A lifting plate 7 is installed in the placement groove 4. One end of the lifting plate 7 is rotatably connected to the connecting column 6, and the other end of the lifting plate 7 can rotate freely.

[0030] A threaded rod 8 is mounted on the upper end of the placement plate 3 via two first mounting blocks 9. One end of the threaded rod 8 is fixedly connected to the output shaft of the first drive motor 10. A moving block 11 is threadedly connected to the side end of the threaded rod 8. A support rod 12 is installed between the moving block 11 and the lifting plate 7. The support rod 12 and the moving block 11 are rotatably connected via a connecting assembly 13. The lifting plate 7 and the support rod 12 are rotatably connected via the connecting assembly 13.

[0031] It should be noted that the threaded rod and the moving block in this utility model meet the thread self-locking condition; that is, the thread helix angle is less than or equal to the equivalent friction angle.

[0032] A rotating shaft 14 is mounted on the upper end of the placement plate 3 via two second mounting blocks 15. Two traction ropes 16 are fixedly connected to the outside of the rotating shaft 14. The end of the traction rope 16 away from the rotating shaft 14 passes through the through groove 5 on the bed board 1 and is located above the bed board 1. A drive assembly for driving the rotating shaft 14 to rotate is installed on the side end of the rotating shaft 14.

[0033] When using the device, the elderly person grasps the pull ring, and then the first drive motor 10 and the drive are started simultaneously. After the first drive motor 10 starts, it drives the threaded rod 8 to rotate, thereby driving the moving block 11 to move closer to the first drive motor 10. This causes the lifting plate 7 to be raised in an inclined position through the support rod 12. At the same time, after the drive component is started, it drives the rotating shaft 14 to rotate, thereby causing the traction rope 16 to be wound up. The combined effect of the lifting plate 7 being raised in an inclined position and the traction rope 16 being wound up pulls the elderly person up, thus helping the elderly person get out of bed.

[0034] In a preferred embodiment of this utility model, the upper end of the bed board 1 has multiple slots 17 at both sides, and guardrails 18 are installed on both sides of the upper end of the bed board 1, with the lower ends of the guardrails 18 inserted into the slots 17. The guardrails 18 are provided to protect the edges of the bed board 1, and their insertion into the slots 17 allows them to be easily removed from the bed board 1.

[0035] In a preferred embodiment of this invention, the connecting assembly 13 includes two connecting blocks 19 and a connecting shaft 20. The connecting shaft 20 is fixedly installed between the two connecting blocks 19 and has a cylindrical structure. The connecting assembly 13 is configured to achieve rotational connections between the support rod 12 and the lifting plate 7, and between the support rod 12 and the moving block 11.

[0036] In a preferred embodiment of this utility model, limiting plates 21 are fixedly installed on both sides of the upper end of the placement plate 3, located on both sides of the threaded rod 8. Limiting grooves 22 are formed on the inner sides of both limiting plates 21. Limiting blocks 23 are fixedly installed on both sides of the moving block 11, and the limiting blocks 23 are adapted to the limiting grooves 22. The limiting plates 21, limiting grooves 22, and limiting blocks 23 are used to limit the movement of the moving block 11, ensuring that the moving block 11 can only move in a straight line when it moves with the rotation of the threaded rod 8.

[0037] In a preferred embodiment of this invention, the drive assembly includes a second drive motor 24 and a drive gear 25. The second drive motor 24 is fixedly mounted on the upper end of the placement plate 3, and the drive gear 25 is fixedly mounted on the output shaft of the second drive motor 24. A driven gear 26 is fixedly mounted on the side end of the rotating shaft 14, and the drive gear 25 and the driven gear 26 are meshed together. The drive assembly is configured to drive the rotating shaft 14 to rotate. After the second drive motor 24 starts, it drives the drive gear 25 to rotate. Since the drive gear 25 and the driven gear 26 are meshed together, the rotation of the drive gear 25 drives the driven gear 26 to rotate, thereby driving the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 drives the traction rope 16 to wind around, thereby achieving the winding of the traction rope 16.

[0038] It should be noted here that: such as Figure 6 and Figure 7 As shown, a limiting component 28 for fixing the driven gear 26 is installed on the upper end of the placement plate 3 at the side end of the driven gear 26. The limiting component 28 includes a connector 29, a connecting shaft 30, a limiting plate 31, and a pin 32. The connector 29 is fixedly installed on the upper end of the placement plate 3. The connecting shaft 30 is rotatably connected to the connector 29. The limiting plate 31 is fixedly installed on the side end of the connecting shaft 30. A plurality of insertion holes 33 are evenly distributed on the side end of the connecting shaft 30. A through hole 34 is opened on the end of the connector 29 near the insertion hole 33. The through hole 34 is adapted to the insertion hole 33, and the pin 32 can pass through the through hole 34 and be inserted into the insertion hole 33. When using the limiting component 28 to fix the driven gear 26, simply rotate the connecting shaft 30 so that the end of the limiting plate 31 away from the connecting shaft 30 abuts against the driven gear 26, and then insert the pin 32 through the through hole 34 into the insertion hole 33. At this time, the limiting plate 31 can limit and fix the driven gear 26, preventing it from rotating. This prevents the traction rope 16 from slipping under force.

[0039] In a preferred embodiment of this invention, a pull ring 27 is fixedly installed at the end of the traction rope 16 away from the pivot point, and an anti-slip layer is provided on the inner side of the pull ring 27. The pull ring 27 is designed to make it easy for the elderly to hold the pull ring 27, thereby using the traction rope 16 to pull the elderly up and assist them in getting out of bed.

[0040] In a preferred embodiment of this utility model, the end of the connecting component 13 connected to the bed board 1 is away from the connecting column 6, and the moving block 11 is located on the side close to the connecting column 6.

[0041] Working principle and usage process of this utility model:

[0042] When using the device, the elderly person grasps the pull ring, and then the first drive motor 10 and the second drive motor 24 are started simultaneously. After the first drive motor 10 starts, it drives the threaded rod 8 to rotate, thereby driving the moving block 11 to move closer to the first drive motor 10. This causes the lifting plate 7 to be raised at an angle via the support rod 12. At the same time, after the second drive motor 24 starts, it drives the driving gear 25 to rotate, thereby driving the driven gear 26 to rotate, which in turn drives the rotating shaft 14 to rotate, thereby causing the traction rope 16 to wind up. The combined effect of the lifting plate 7 rising at an angle and the winding of the traction rope 16 pulls the elderly person up, thus helping them get out of bed.
