[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing an adjustable nursing bed with a structure that allows patients to naturally dangle their legs when sitting up, resulting in a comfortable sitting posture.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] An adjustable nursing bed includes a bed frame, a primary support plate, a sliding toothed plate, a toothed disc, a rotating shaft support plate, a spring, a positioning block, a support plate, a rotating frame, a central rotating frame, and a lifting frame. The bed frame has multiple upper frame rods connected to its lower part, with four moving wheels distributed at the four corners of the bottom of the bed frame. The rotating frame is adapted to the bed frame and inserted into it. Side positioning rotating shafts are connected to the sides of the rotating frame, symmetrically arranged at both ends. The side of the bed frame has rotating shaft insertion holes. The side positioning pivot is adapted to the pivot insertion hole. The side positioning pivot is inserted into the pivot insertion hole and rotates within the pivot insertion hole. The pivot insertion hole is connected inside the nursing bed frame. The lower surface of the rotating frame is in contact with the support plate. The lower part of the rotating frame is connected to the lower triangular plate. The rotating top rod passes through the lower triangular plate and rotates within the lower triangular plate. The rotating top rod is connected to the top plate. A set of top plates are distributed on the rotating top rod. The side of the top plate is in contact with the lower triangular plate. The lower part of the first support plate is connected to the nursing bed frame. The lower part of the second support plate is connected to the nursing bed frame.
[0006] The sliding toothed plate is adapted to the first support plate and the second support plate.

Beneficial effects
[0008] 1. This utility model features four movable wheels distributed at the bottom of the nursing bed frame, facilitating easy movement of the entire nursing bed during use. A side positioning pivot passes through a pivot insertion hole and connects to a rotating frame, allowing the rotating frame to be mounted on the nursing bed frame and rotatable. The rotating frame's rotatable structure allows it to be adjusted during use, raising it to provide support for the patient's back. A support plate is mounted on the nursing bed frame, providing auxiliary support for the rotating frame during rotation. A rotating top rod passes through a lower triangular plate, which is fixed to the bottom of the rotating frame. Support plates one and two are mounted and fixed on the nursing bed frame. A sliding toothed plate passes through support plates one and two. The support plates, namely the first and second support plates, support and limit the sliding toothed plate without affecting its horizontal sliding. The sliding toothed plate is designed for horizontal sliding, allowing the top plate to push the rotating frame to rotate. A set of rotating shaft support plates is installed and fixed on the nursing bed frame, and another set of rotating shaft support plates supports the toothed disc shaft. When the toothed disc shaft rotates, it drives the toothed disc to rotate, causing the toothed disc to drive the sliding toothed plate to slide horizontally. The rotation of the toothed disc can be controlled by rotating a rocker arm. The upper part of the positioning block engages with the toothed disc, and the positioning block positions the toothed disc axially. During the use of the adjustable nursing bed, it prevents the sliding toothed plate from sliding under the reverse pressure of the top plate, thereby limiting the rotation angle of the rotating frame.
[0009] 2. In this utility model, the limiting slide rod passes through the spring and is inserted into the rotating shaft support plate. The limiting slide rod positions the positioning block, and the spring pushes the positioning block. During the use of the adjustable nursing bed, it prevents the positioning block from disconnecting from the gear plate. When it is necessary to rotate the gear plate, the limiting slide rod is pulled to disconnect the positioning block from the gear plate. The right ear of the rotating frame is connected to the side trunnion of the bed frame, and the left ear of the rotating frame is connected to the side trunnion of the lifting frame, so that the middle rotating frame can rotate relative to the nursing bed frame and the lifting frame. The upper and lower ends of the cylinder are connected to the lower ear and lower connecting trunnion of the rotating frame, respectively, so that the cylinder pushes and pulls the middle rotating frame during use. When the patient needs to sit up, the cylinder piston rod retracts, causing the middle rotating frame to rotate and the lifting frame to fall naturally until the lower plate of the tail plate is in contact with the ground. At this time, the lifting frame can be used as a footrest for the patient. The adjustable structure of this nursing bed allows the patient's legs to hang down naturally when sitting up, resulting in a comfortable sitting posture. Attached Figure Description

The side of the rotating frame 17 is connected to the side positioning shaft 18, which is symmetrically arranged at both ends of the rotating frame 17. The side of the nursing bed frame 01 has a shaft insertion hole 16, which is adapted to the side positioning shaft 18. The side positioning shaft 18 is inserted into the shaft insertion hole 16 and rotates within it, thus mounting the rotating frame 17 on the nursing bed frame. The rotating frame 17 is rotatable and can be raised to provide support for the patient's back during use. The rotating frame 17 is internally connected to a pivot hole 16. The lower surface of the rotating frame 17 is in contact with a support plate 15, which is mounted on the nursing bed frame 01 to provide auxiliary support for the rotating frame 17 during rotation. A lower triangular plate 19 is connected to the lower part of the rotating frame 17. Triangular plate 19 is fixed to the bottom of rotating frame 17. Rotating top rod 20 passes through lower triangular plate 19 and rotates inside lower triangular plate 19. Rotating top rod 20 is connected to top plate 21. A set of top plates 21 are distributed on rotating top rod 20. The side of top plate 21 is in contact with lower triangular plate 19. The lower part of first support plate 04 is connected to nursing bed frame 01. The lower part of second support plate 05 is connected to nursing bed frame 01. First support plate 04 and second support plate 05 are installed and fixed on nursing bed frame 01.
[0019] Example 2:
[0020] The sliding toothed plate 07 of this utility model is adapted to the first support plate 04 and the second support plate 05. The sliding toothed plate 07 passes through the first support plate 04 and the second support plate 05 in sequence. The first support plate 04 and the second support plate 05 support and limit the sliding toothed plate 07 without affecting the horizontal sliding of the sliding toothed plate 07.

The lower surface of the top plate 21 is in contact with the upper surface of the sliding toothed plate 07. The side of the top plate 21 is in contact with the toothed plate protrusion 31. The sliding toothed plate 07 is configured to slide horizontally, so that the top plate 21 pushes the rotating frame 17 to rotate. The toothed plate protrusion 31 is adapted to the notch 06 on the support plate and passes through the notch 06 on the support plate.
[0021] Example 3:
[0022] The present invention describes a toothed disc 08 connected to a toothed disc shaft 09. A set of toothed discs 08 are distributed on the toothed disc shaft 09, and the toothed discs 08 mesh with the lower part of sliding toothed plates 07. A set of sliding toothed plates 07 are distributed on the nursing bed frame 01. The lower part of the shaft support plate 10 is connected to the nursing bed frame 01, and the toothed disc shaft 09 passes through the shaft support plate 10. A set of shaft support plates 10 are distributed on the toothed disc shaft 09. A rocker arm 14 is connected to the toothed disc 08. A set of shaft support plates 10 are installed and fixed on the nursing bed frame 01, and the set of shaft support plates 10 supports the toothed disc shaft 09. When 09 rotates, it drives the gear plate 08 to rotate, causing the gear plate 08 to slide horizontally along the sliding tooth plate 07. The rotation of the gear plate 08 can be controlled by rotating the rocker arm 14. The upper part of the positioning block 13 meshes with the gear plate 08, and the positioning block 13 positions the gear plate 08 axially. During the use of the adjustable nursing bed, it prevents the sliding tooth plate 07 from sliding under the reverse pressure of the top plate 21, thereby limiting the rotation angle of the rotating frame 17. The side of the positioning block 13 has a limiting slide rod 11, which passes through the rotating shaft support plate 10 and slides within the rotating shaft support plate 10.
[0023] Example 4:
[0024] The spring 12 described in this utility model is sleeved on the limiting slide rod 11. One end of the spring 12 abuts against the positioning block 13, and the other end of the spring 12 abuts against the rotating shaft support plate 10. The limiting slide rod 11 positions the positioning block 13, and the spring 12 pushes the positioning block 13. During the use of the adjustable nursing bed, this prevents the positioning block 13 from disconnecting from the gear disc 08. When it is necessary to rotate the gear disc 08, pulling the limiting slide rod 11 will disconnect the positioning block 13 from the gear disc 08. The lower part of the limiting plate 34 is connected... The nursing bed frame 01 is connected to the side of the limiting plate 34, which is attached to the positioning block 13. The side of the nursing bed frame 01 has a side ear 03, and the side of the middle rotating frame 22 has a right ear 24. The right ear 24 is axially connected to the side ear 03. The other end of the middle rotating frame 22 has a left ear 25. The side of the lifting frame 26 has a side ear 27. The left ear 25 is axially connected to the side ear 27, so that the middle rotating frame 22 can rotate relative to the nursing bed frame 01 and the lifting frame 26.
[0025] Example 5:
[0026] The lifting frame 26 of this utility model is connected to the bed tail plate 29 on the side. The bed tail plate 29 has a lower tail plate 30 at the bottom. The lifting frame 26 has a support plate 28 at the bottom. The lower surface of the intermediate rotating frame 22 is in contact with the support plate 28. The intermediate rotating frame 22 has a rotating frame lower ear 23 at the bottom. The nursing bed frame 01 has a lower connecting ear 35. The upper and lower ends of the cylinder 33 are respectively shaft connected to the rotating frame lower ear 23 and the lower connecting ear 35, so that the cylinder 33 pushes and pulls the intermediate rotating frame 22 when in use. When the patient needs to sit up, the piston rod of the cylinder 33 retracts, causing the intermediate rotating frame 22 to rotate, so that the lifting frame 26 falls naturally until the lower tail plate 30 is in contact with the ground. At this time, the lifting frame 26 can be used as a footrest for the patient. The adjustment structure of this nursing bed allows the patient's legs to hang down naturally when sitting up, making the sitting posture comfortable.
