Connected, an electric push rod 5 is installed on one side outside the top of the bed frame 6 .

Working principle: For this type of multifunctional wheelchair, when in use, the guardrail gasket 2, the head bed frame 4 and the motor body 21 use the motor as the power source, and the motor rotates forward and reverse to make the hydraulic oil output pressure through the bidirectional gear pump. The oil is sent to the working cylinder through the oil circuit integrated block to realize the reciprocating motion of the piston rod. When the user spreads it flatly, each push rod is in a fully retracted state. It can be put down, hold the side top guard horizontally, lift it up about 20mm vertically, and then pull it out. At this time, under the action of the parallelogram mechanism, the adjustable bed changes from a vertical state to a horizontal state, and is supported by the fixed side of the parallelogram. Hold, so that the adjustable horizontal state can be maintained, and then hold the top edge of the side guardrail horizontally to make it hang down by 20 mm, and there are pegs inserted into the limit slot to fix the guardrail;

If the user wants to sit up, the user presses the button, the support back will be retracted by the guardrail washer 2, and the lower link will be retracted under the action of the guardrail washer 2. At this time, under the action of the force, the link is slowly Upward, the angle can be adjusted according to the user's preference. If the feet feel uncomfortable, the leg support can be switched through the switch, and can also be raised or lowered by the user's adjustment. Under the contraction of the motor body 21, the leg support can be slowed down Slowly down, and thus completes the entire process of using the multifunctional wheelchair.
