Inclination-angle-adjustable mechanism and sickbed with same

Abstract

The invention discloses an inclination-angle-adjustable mechanism. The mechanism comprises a snap ring curved bar. One end of the snap ring curved bar is connected with a rocking bar, the lower portion of the snap ring curved bar is connected with a connecting bar, a crank is arranged below the connecting bar, a transmission shaft placed horizontally is arranged in the center of the crank, a gear is arranged on the transmission shaft, a rack is arranged below the gear, meshed with the gear and placed in the direction perpendicular to the transmission shaft, a rack bar is arranged below the rack, a telescopic lifting bar is hinged to the front end of the rack bar, and the rack and the rack bar are both installed on a rack support. The mechanism is simple in structure, easy to obtain and applicable to common beds, sickbeds, sofas, deck chairs and the like, overcomes the defect that in the prior art, the angle of the articles is fixed, and effectively increases use comfort. The invention further discloses a sickbed with the inclination-angle-adjustable mechanism. The sickbed relieves the labor intensity of nurses greatly and is high in stability and safety, convenient to use, practical and worthy of wide popularization.

Description

technical field [0001] The invention specifically relates to a mechanism capable of adjusting an inclination angle and a hospital bed for its application. Background technique [0002] At present, ordinary beds, sofas, recliners, and other daily necessities that lift weights are mostly fixed at an angle, either horizontally or at a certain angle. Often, after a person maintains a certain posture for a certain period of time, numbness and numbness of the hands and feet will occur. Fatigue states such as tiredness need to adjust the angle, but there is no such adjustment mechanism in the prior art. [0003] In addition, the hand-operated folding structures of the existing hospital beds all require nursing staff to complete the operation, and patients cannot operate by themselves, especially paralyzed, unable to walk on both feet or critically ill patients. Sitting up temporarily or daily activities such as eating and drinking require the help of nursing staff at all times. T...

[0002] At present, ordinary beds, sofas, recliners, and other daily necessities that lift weights are mostly fixed at an angle, either horizontally or at a certain angle. Often, after a person maintains a certain posture for a certain period of time, numbness and numbness of the hands and feet will occur. Tiredness and other fatigue states need to adjust the angle, but there is no such adjustment mechanism in the prior art

[0003] In addition, the hand-operated folding structures of the existing hospital beds all require nursing staff to complete the operation, and patients cannot operate by themselves, especially paralyzed, unable to walk on both feet or critically ill patients. Sitting up temporarily or daily activities such as eating and drinking, requiring the help of nursing staff at all times

The hospital bed of this structure can't provide convenience to the patient, has increased the labor intensity of nursing staff greatly at the same time
