Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multifunctional elderly care chair, aiming to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a multifunctional elderly care chair, comprising a support frame, on which a support assembly is arranged.

[0006] The support assembly includes a deflection frame arranged on the support frame, the deflection frame is rotatably connected to the support frame, a protective cover is arranged on the deflection frame, baffles are arranged at both ends of the extension frame, and each of the baffles is rotatably connected to a support wheel, a ball cover is fixedly arranged at one end of the support frame, and a support ball is rotatably connected inside the ball cover.

[0007] It can be seen that in the above technical solution, the staff opens the deflection frame, and the deflection frame rotates along the axis point of the connection between the deflection frame and the support frame, thereby enabling the protective cover to be opened, and the device can be transported via the support balls and support wheels.

[0008] An extension frame is provided at the bottom of the support frame, a hip support is provided at the top of the extension frame, a back support is provided at one side of the hip support, a first protective pad is fixedly provided at both sides of the hip support, a second protective pad is fixedly provided at both sides of the back support, a third protective pad is fixedly provided at the top of the back support, a leg support is provided at the side of the hip support away from the back support, the leg support is rotatably connected to the extension frame, one end of the leg support is rotatably connected to an extension rod, and foot plates are inserted at both sides of the extension rod.

[0009] It can be seen that in the above technical solution, the patient's buttocks on the device can be supported by the buttocks support, the first protective pad can limit the sides of the patient's buttocks, the leg support supports the patient's legs, and the foot board supports the patient's feet, first preventing the patient from slipping and causing secondary injuries.

[0010] The back support is provided with a connecting block on one side of the connecting block, and a plurality of connecting members are fixedly provided with splints on both sides of each of the connecting members, and an elastic plate is clamped on multiple splints, and a silicone pad is provided on one end of each of the elastic plates, and a first knob is fixedly provided on one side of the connecting member, and the first knob is rotatably connected to the second knob, and an inclined rod is fixedly provided on the second knob, and the inclined rod is tiltedly arranged, and a transverse axis block is rotatably connected to the inclined rod through an axle pin, and a spring cylinder is fixedly provided on the transverse axis block, one end of the spring cylinder is slidably connected to an axle pin rod, and a spring is arranged between the axle pin rod and the spring cylinder, one end of the axle pin rod extends to the connecting member and is rotatably connected to the connecting member, and a pulling member is rotatably connected to the oblique rod, and the pulling member extends to the connecting member and is rotatably connected to the connecting member, and multiple connecting members are arranged side by side, and the oblique rods on each adjacent connecting member extend to the transverse axis block and the pulling member belonging to the adjacent connecting member.

[0011] It can be seen that in the above technical solution, the silicone pad is subjected to force to drive the connector to move. When the connector is displaced, the puller will rotate along the axis point of the connection between the puller, the inclined rod and the connector, thereby realizing the function of supporting the connector when it is deflected. When the angle of the connector changes, the axle pin will be pulled to move and the spring will be compressed. The connector is reset through the elasticity of the spring itself, and then the connector, splint, elastic plate and silicone pad are moved closer to the patient's back, which is easy to automatically adjust and fit according to the curvature of the patient's spine, thereby improving the comfort of the patient lying on the device. The inclined rod rotates on the first knob through the second knob, and then the adjacent connector is deflected by the torque of the rotation of the inclined rod, so that each connector can be linked with each other for adaptive angle and position adjustment, and can better fit the patient's back.

[0012] Technical effects and advantages of the present invention: 1. The present invention rotates the deflection frame along the axis point where the deflection frame is connected to the support frame, thereby opening the protective cover, and the device can be transported through the support ball and the support wheel, so that the patient can lie on the device easily, and the protective cover can be closed and opened to shield the patient and prevent the patient from being affected by wind and cold and aggravating the condition; 2. The present invention can support the patient's buttocks through the buttock support, while the first protective pad can limit the positions of both sides of the patient's buttocks, the leg support supports the patient's legs, and the foot board supports the patient's feet, so as to prevent the patient from slipping and causing secondary injuries, and make it easier for the staff to perform nursing work on the patient; 3. The back support of the present invention is deformed by force and squeezes the silicone pad. The silicone pad is forced to drive the connector to move. When the connector moves, the pull member rotates along the axis point of the connection between the pull member, the inclined rod and the connector, so as to realize the function of supporting the connector when it is deflected. When the angle of the connector changes, the shaft pin rod is pulled to move and the spring is compressed. The elasticity of the spring drives the connector to reset, and then the connector, the splint, the elastic plate and the silicone pad are moved closer to the patient's back. It is easy to automatically adjust according to the curvature of the patient's spine and fit it, thereby improving the comfort of the patient lying on the device. 4. In the present invention, when a single connecting member is displaced by force, the inclined rod rotates on the first knob through the second knob, and then the adjacent connecting members are deflected by the torque of the rotating inclined rod, so that each connecting member can be linked with each other to perform adaptive angle and position adjustment, and can better fit the patient's back; To sum up, the overall design is simple and the structure is reasonable. Through the corresponding coordination of various structures and the closing and opening of the protective cover, it is easy to shield the patient and prevent him from being affected by wind and cold and aggravating his condition. When the back support is deformed by force and squeezes the silicone pad, the shaft pin rod will be displaced and the spring will be compressed when the angle of the connecting part changes. The spring's own elastic drive drives the connecting part to reset, and then the connecting part, splint, elastic plate and silicone pad are moved closer to the patient's back. It is easy to automatically adjust and fit the patient's spine curvature shape, thereby improving the patient's comfort when lying on the device. The adjacent connecting parts are deflected by the torque of the rotating inclined rod, so that each connecting part can be linked with each other for adaptive angle and position adjustment, which can better fit the patient's back and make it easier for the patient to transfer.
