[0002] Nursing beds are generally powered beds, divided into electric or manual nursing beds, which are designed according to the patient's bedridden lifestyle and treatment needs, and can be accompanied by family members, have multiple nursing functions and operation buttons, and are insulated and safe to use. However, when the existing nursing beds are adjusted to raise the back bed board, the operator is often unclear about the specific adjustment angle, which is not convenient for some special patients who need to be nursed at a certain angle.

[0003] In order to solve the above-mentioned patent publication number CN214806154U, a back adjustment device for a manual nursing bed is disclosed. The technical solution disclosed in the patent can adjust the back bed board to an accurate clear tilt angle when adjusting and raising it, which is convenient for some special patients who need a certain angle for nursing. However, the technical solution disclosed in the above patent still has the following problems: during the angle adjustment process of the back bed board, the rotation speed of the back bed board is completely controlled by the rotation speed of the hand wheel. Generally, the hand wheel on this type of existing nursing bed needs to be rotated many times before the back bed board can be slowly lowered. The back panel of the current manual nursing bed cannot realize the function of fast flattening. When the back panel is laid down, the operator needs to shake the handle to make the back panel flat, and the flattening speed is very slow. The back panel is not laid down fast enough, which will affect the patient's first aid time, such as cardiopulmonary resuscitation. At the same time, some patients need to slowly lay down the back panel when adjusting the back panel. Therefore, this type of existing nursing bed disclosed in the patent cannot realize the adjustment of the lowering speed of the back panel. Utility Model Content

[0026] Example

[0027] Please refer to Figure 1-Figure 6 , Figure 1 Shown is a schematic structural diagram of an embodiment of the utility model; Figure 2 This is a schematic diagram of the installation structure of the foot-operated actuator in the embodiment of the utility model; Figure 3 for Figure 2 The enlarged view of point A in the middle; Figure 4 This is a schematic diagram of the structure of the flip member in the embodiment of the utility model; Figure 5 for Figure 4 The enlarged view of point B in the middle; Figure 6 It is a side view of an embodiment of the utility model. This embodiment provides a back adjustment device for a manual nursing bed, comprising a bed frame 1, a bed board 2 and an adjustment assembly. The bed frame 1 is the main component of the nursing bed, which is used to install and carry other components to facilitate the patient to stay away from the ground. The bed board 2 is used for the patient to lie flat, and the adjustment assembly is used to adjust the rotation of the back board 201 below.

[0028] In this embodiment, the bed board 2 includes a backboard 201, which is rotatably connected to the bed board 2. The adjustment assembly includes a flip member and a power input shaft 9. The flip member is connected to the backboard 201 to drive the backboard 201 to rotate along the bed frame 1. A transmission 10 is connected between the power input shaft 9 and the flip member.

[0029] In this embodiment, the backboard 201 in the bed board 2 is used to support the patient's back, and the backboard 201 can be adjusted to support the patient's back after rotating around the bed board 2. The flip member is used to drive the backboard 201 to rotate to a desired position. The power input shaft 9 is used to drive the flip member to move, so that the flip member drives the back to rotate. The rotation speed of the power input shaft 9 determines the rotation rate of the backboard 201. The transmission 10 can change the rotation rate output of the power input shaft 9 to the flip member, so that the speed of the backboard 201 is adjusted through the transmission 10 to meet the speed change requirements of different patients.

[0030] Therefore, the back adjustment device of the manual nursing bed can achieve speed change when adjusting the back panel 201 and can perform adaptive speed change as needed, which greatly improves the convenience of back adjustment.

[0031] In some implementations of the present embodiment, the flip member includes a screw rod 3, a guide rail 4, a slider 5, a first connecting rod 6, a second connecting rod 7 and a third connecting rod 8. One end of the first connecting rod 6 is hinged to the bed frame 1, and the other end is connected to one end of the second connecting rod 7. The free end of the second connecting rod 7 is hinged to the back plate 201. The first connecting rod 6 can rotate with the back plate 201. One end of the third connecting rod 8 is hinged to the middle part of the first connecting rod 6, and the other end is hinged to the slider 5. The guide rail 4 is arranged on the bed frame 1 along the rotational diameter of the first connecting rod 6. The slider 5 is slidably arranged on the guide rail 4. The screw rod 3 is rotatably arranged on the bed frame 1 along the extension direction of the guide rail 4. The screw rod 3 passes through the slider 5 and is threadedly connected to the slider 5. One end of the screw rod 3 is connected to the power input shaft 9.

[0032] In this embodiment, the screw rod 3, the guide rail 4 and the slider 5 constitute a screw rod 3 mechanism. Since the screw rod 3 is threadedly connected to the slider 5, and the slider 5 can only slide along the extension direction of the guide rail 4, the screw rod 3 can convert its selective motion into the linear motion of the slider 5 after it rotates. Since the slider 5 is hinged to the third connecting rod 8, the slider 5 will drive the first connecting rod 6 to rotate after it moves, so that after the first connecting rod 6 drives the second connecting rod 7 to move, the back plate 201 is driven to rotate.

[0033] In some implementations of this embodiment, the power input shaft 9 is connected to a driving member, and the driving member is used to drive the power input shaft 9 to rotate. In this embodiment, the driving member is used to drive the power input shaft 9 to rotate.

[0034] In some implementations of this embodiment, the driving member includes a pedal driver, which is connected to the power input shaft 9 and is used to drive the power input shaft 9 to rotate by pedaling. In this embodiment, the pedal driver is used to drive the power input shaft 9 to rotate by pedaling. Compared with the following hand-cranked wheel method, this driving method does not require the driver to bend down to rotate the hand-cranked wheel, and can more conveniently and quickly adjust the rotation angle of the backboard 201.

[0035] In other embodiments, the driving member includes a manual driver, and the manual driver includes a hand wheel, and the hand wheel is arranged at the free end of the power input shaft 9. The hand wheel can be manually rotated to drive the power input shaft 9 to rotate.

[0036] In some implementations of the present embodiment, the foot-operated driver includes a base 11, a pedal 12, a crankshaft 13, a collar 14 and a power rod 15. A hinge support is provided on the base 11, the middle part of the pedal 12 is hingedly connected to the hinge support, one end of the crankshaft 13 is coaxially connected to the power input shaft 9, the collar 14 is sleeved on the connecting rod journal of the crankshaft 13 and can rotate freely around the connecting rod journal, one end of the power rod 15 is connected to the collar 14, and the other end is hinged to one end of the pedal 12.

[0037] In this embodiment, the pedal 12 is rotated back and forth when stepped on the base 11. Since the power sense is connected to the pedal 12 and the collar 14, the power rod 15 can drive the crankshaft 13 to rotate. In this way, the crankshaft 13 can drive the power input shaft 9 to rotate.

[0038] In some implementations of this embodiment, a moving wheel 16 is provided at the bottom of the bed frame 1. In this embodiment, the moving wheel 16 can realize the movement of the bed frame 1.

[0039] When in use, first adjust the rotation rate by adjusting the gear position of the transmission 10. Then, step on the pedal 12 with your foot, and the pedal 12 rotates back and forth on the base 11 after being stepped on. Since the power sense is connected to the pedal 12 and the collar 14, the power rod 15 can drive the crankshaft 13 to rotate. In this way, the crankshaft 13 can drive the power input shaft 9 to rotate. After the power input shaft 9 rotates, it changes speed through the transmission 10, and then drives the screw 3 to rotate. After the screw 3 rotates, its selected motion can be converted into the linear motion of the slider 5. Since the slider 5 is hinged to the third connecting rod 8, the slider 5 will drive the first connecting rod 6 to rotate after it moves, so that after the first connecting rod 6 drives the second connecting rod 7 to move, it drives the back plate 201 to rotate to the required position.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
