Description

Technical Field

[0001] The utility model relates to the field of medical care equipment and supplies, and in particular to a health care nursing bed. Background Art

[0002] Beds are important furniture for us to sleep, but in life there are not only ordinary beds for sleeping, but also beds that help patients recover or are specially used by the elderly. This kind of bed is called a multi-functional nursing bed. The multi-functional nursing bed can not only be used as a simple bed, but also has a nursing function, assisting doctors to help patients recover more quickly, and truly achieves the characteristics of one thing for multiple uses. It is now widely used in hospitals and clinics. Each thing has different classifications. Multi-functional nursing beds can be divided into three categories: electric, hand-cranked and ordinary nursing beds according to the needs of patients. These three categories also have different scopes of use. Multi-functional electric nursing beds have an auxiliary effect on the prevention and treatment of the three major complications of long-term bedridden patients. Hand-cranked nursing beds are suitable for ordinary wards, such as wards that have just completed a minor dislocation bone setting operation. There is also a simplest nursing bed, which is suitable for relatively ordinary patients, but the existing nursing beds are not convenient to use for the needs of the elderly to strengthen exercise and need more sun exposure. Therefore, a health care nursing bed is needed that allows the elderly to go out and sunbathe without getting out of bed.

[0003] The currently disclosed Chinese patent CN209984474U discloses a multifunctional elderly health care bed, comprising a left bed board and a right bed board, a rotating shaft between the left bed board and the right bed board, and the right bed board rotates on the rotating shaft, a drawer is arranged inside the left bed board, and a first supporting leg and a second supporting leg are arranged on the lower surface of the left bed board, the first supporting leg is provided with an axle pin, an internally threaded cylinder and a directional wheel, and the second supporting leg is provided with a universal wheel, a connecting shaft and an adjusting cylinder. Since the first supporting leg and the second supporting leg can be folded, it is convenient for the directional wheel and the universal wheel to contact the ground, so that the device can be moved on the ground. In addition, the right bed board can be rotated to the left to facilitate the user to push the device to move. The arranged drawer can also carry items, which is convenient to use. Since the device is provided with an adjusting cylinder and an internally threaded cylinder, the height of the left bed board can be adjusted. Therefore, the utility model is easy to use and move, and the height of the left bed board can be adjusted, so it is worthy of promotion.

[0004] According to the above patent, the device requires the bed to be folded manually, and no one can be on the bed during the folding process, which is particularly inconvenient for elderly people with mobility problems. Utility Model Content

One end of the handle body 414 is hingedly provided with the hinge seat 413, and the other end of the handle extends in the direction of the foot of the bed 12. The second sleeve 415 is provided on the handle body 414 close to the head of the bed. On one side of 11, one end of the second sleeve 415 is connected to the handle body 414, one end of the driven rod 417 is arranged inside the second sleeve 415, one end of the driven rod 417 is provided with a spring 416, one end of the spring 416 is abutted against the driven rod 417, and the other end of the spring 416 is abutted against the handle body 414 inside the second sleeve 415, and the end of the driven rod 417 away from the spring 416 is provided with a universal ball 418, the universal ball 418 is connected to the driven rod 417, the working end of the universal ball 418 is abutted against the hinge seat 413, and the hinge seat 413 is provided with a groove matched with the universal ball 418.

[0067] When the back support plate 41 is erected, the handle body 414 is pulled by hand, and the handle body 414 drives the second sleeve 4152123 to rotate, and the second sleeve 415 drives the spring 416, the driven rod 417 and the universal ball 418 connected thereto to rotate. When the handle body 414 is rotated into place, the universal ball 418 will roll into the pre-set groove, so that the handle body 414 cannot continue to rotate.

[0068] Reference Figure 6 and Figure 7As shown, the opening and closing assembly 14 includes a first rotating plate 15, a second rotating plate 16 and a fourth rotating shaft 17. The first rotating plate 15 is arranged at an opening of the bed frame 13 on the side close to the head of the bed 11, and the second rotating plate 16 is arranged at an opening of the bed frame 13 on the side close to the foot of the bed 12. The fourth rotating shaft 17 is arranged at both ends of the bed frame 13. The fourth rotating shaft 17 is rotatably connected with the corresponding first rotating plate 15, the second rotating plate 16 and the bed frame 13 respectively, and a clamping assembly 131 is arranged on the first rotating plate 15.

[0069] When the wheelchair needs to be pushed out, the clamping assembly 131 is first opened manually, and then the first rotating plate 15 and the second rotating plate 16 are pulled apart by hand, so that the opening on the bed frame 13 is opened, so that the wheelchair can be pushed out more easily.

[0070] Reference Figure 1 and Figure 2 As shown, a clamping assembly 131 is provided on the first rotating plate 15, and the clamping assembly 131 includes a clamping seat 132 and a clamping plate 133. The clamping seat 132 is arranged on the side of the first rotating plate 15 away from the back support plate 41, and the clamping seat 132 is connected to the first rotating plate 15. An opening is provided on the top of the first rotating plate 15, and the clamping plate 133 is arranged at one end of the second rotating plate 16 close to the clamping seat 132. One end of the clamping plate 133 is rotatably connected to the second rotating plate 16, and the other end of the clamping plate 133 can be connected to the clamping seat 132.

[0071] First, the clamping plate 133 is rotated to disconnect the clamping plate 133 from the clamping seat 132 assembly.

[0072] Reference Figure 3 and Figure 5 As shown, a second limiting portion 134 is also provided on the bed frame 13, and the second limiting portion 134 includes a limiting rod 135. The limiting rod 135 is located in the middle of the bed frame 13, and one end of the limiting rod 135 is connected to the bed frame 13. The limiting rod 135 faces the hip support plate 42, and a groove cooperating with the hip support plate 42 is provided on one side of the hip support plate 42 close to the limiting rod 135.

[0073] When the wheelchair is to be pushed back to the bed frame 13 , the limiting rod 135 and the groove can play a positioning role, so that the wheelchair will not collide with the bed frame 13 when it is turned back into the folding bed board 4 .

[0074] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
