The working principle thereof will be described in detail below:

referring to fig. 5, fig. 5 is a schematic view illustrating a use condition of a power assisting device based on traction and lifting according to the present application.

The user wears the waistband well firstly, buckles the safety belt, adjusts the length of the hauling ropes on the two sides and then connects the hauling ropes with the waistband through the buckle rings. At the moment, the user is still in a squatting or sitting state, the stability of connection is checked, the adjusting button can be pressed down, and the user can slowly stand up by means of the traction mechanism. When the adjusting button is pressed, the winch is electrified, the rotating shaft rotates, and the traction rope is wound on the rotating shaft. The traction rope is divided into two sections, extends to two sides of the guide wheel rod through the wire distributing wheel respectively, turns at the guide wheels at two ends of the guide wheel rod, extends upwards along the direction of the side frame, and finally bypasses the guide wheels to be connected with the waistband. Therefore, when the winding machine is used for winding, the length of the traction rope is shortened, a user is pulled to approach the guide wheel, and people stand. The user can also adjust the length of handrail subassembly as required to the demand of adaptation different people.

When a user goes to a toilet or wants to sit on a chair, the opening of the bottom frame can be fixed on two sides of furniture such as a toilet or a stool, the adjusting button is pressed to control the winch to pay off, the length of the traction rope is lengthened, and the user is far away from the guide wheel under the action of gravity and sits slowly in a designated area. If sitting on the bed, the user only needs to push the bottom frame into the bottom of the bed, and after the steps are repeated, the user can go to sleep by unfastening the safety belt and the waistband.

When a user needs to move, the user only needs to lean the elbows on the elbow pads, and can independently move by holding the armrest handles with both hands, so that the difficulty in walking is reduced. When the user falls down due to accident or unconsciousness, the whole body weight of the user presses the device completely, the weight exceeds the supporting range of the rear wheel spring, the rear wheel moves upwards relative to the chassis, and the friction block is in contact with the ground to play a role in braking. Meanwhile, the winch can be automatically locked in the falling process, so that the device is prevented from being forced to turn backwards.

Furthermore, this application a power assisting device based on pull lifting can also increase the height-adjusting function of device to satisfy different height crowds' demand. At the moment, the side frame is of a telescopic structure and is divided into three sections along the height direction, and each section is sleeved with each other and fixed through a screw, so that the adjusting function is realized. In addition, the side frame can also be of a folding structure and is divided into three sections along the height direction, each section is connected through a joint, the bending angle of the section can be adjusted at will, and stepless adjustment on the height is realized.

The power assisting device based on traction and lifting is simple in structure and convenient to operate. The user only needs to buckle the traction rope on the waistband and fasten the safety belt, so that the body can be fixed without independently supporting the body stably, and the requirement on the strength of the upper limbs is reduced. Simultaneously, this device utilizes haulage rope and hoist engine to use coordinately, makes old man's accessible operation height button control the height of rope to drive the getting up and sitting down of health, avoid the knee to bear the weight of whole body and lead to the condition of joint gall, squatting pan unstability, and provide the helping hand for the action of getting up, alleviateed old man's the degree of exerting oneself.
