[0019] See also Figure 1-Figure 13 The present invention provides a multifunctional nursing device for elderly cardiology, comprising an auxiliary seat body 1; further comprising a sliding member, a movable member and a fixed plate 2 rotatably connected to the auxiliary seat body 1, wherein a movable plate 3 (with ratchet plate structures on both sides) for lifting and supporting elderly patients is slidably matched on the fixed plate 2, and a movable plate 4 is rotatably connected to the bottom of the fixed plate 2, and two toggle plates 5 (with ratchet plate structures) matched with the movable plate 3 are rotatably connected in the movable plate 4 through a sliding member, and a reset rod 6 matched with the toggle plate 5 is rotatably connected to the fixed plate 2, and a self-rotating plate 7 is self-rotating on the auxiliary seat body 1, and the self-rotating plate 7 reciprocates the movable plate 4 through the movable member, wherein a shell can be provided to protect the movable plate 3, and a notch is provided on the shell to facilitate the movement of the movable plate 44 and the toggle plate 5; The sliding member includes a sleeve plate 8 that is slidably matched with the movable plate 4. The sleeve plate 8 enables the toggle plate 5 to move along the movable plate 4 through the movable member, thereby pressing and driving the fixed plate 2 and the lifting movable plate 3 to tilt synchronously, so as to facilitate the elderly patient's upper limbs to move forward and leave the backrest of the auxiliary seat body 1; Through the movable parts, the movable plate 4 and the sleeve plate 8 are made to reciprocate at a certain angle, and the sleeve plate 8 moves along the movable plate 4. In this method, the toggle plate 5 is rotated back and forth at a certain angle, so that the movable plate 3 moves upward layer by layer, driving the bracket 12 to support the upper body of the elderly patient to separate from the auxiliary seat body 1, and the toggle plate 5 moves along the movable plate 4, so that the toggle plate 5 away from the position of the elliptical wheel 24 is close to the movable plate 3, and the other toggle plate 5 is away from the movable plate 3, so that the force of the toggle plate 5 away from the position of the elliptical wheel 24 on the movable plate 3 is greater than the effect of the other toggle plate 5 on the movable plate 3, so that the movable plate 3 is tilted, and the upward movement of the movable plate 3 along the fixed plate 2 is not affected, so that the rising bracket 12 is tilted, the back of the elderly patient is separated from the auxiliary seat body 1, and the elderly patient is assisted to stand up from the auxiliary seat body 1. This method is easy to operate and has a strong auxiliary effect.

[0020] The sliding member also includes a protrusion 9 rotatably connected to the toggle plate 5 through a torsion spring, a first sliding groove 10 slidably matched with the protrusion 9 is opened on one side of the movable plate 4, and a second sliding groove 11 matched with the movable member is opened on the other side of the movable plate 4. A bracket 12 for supporting the arm of the elderly patient is fixedly connected to the top of the movable plate 3, and a limiter is provided between the movable plate 3 and the fixed plate 2; Through the movable parts, the movable plate 4 and the sleeve plate 8 are reciprocated at a certain angle, and the sleeve plate 8 moves along the movable plate 4; That is, the protrusion 9 drives the two toggle plates 5 to rotate back and forth synchronously, and the two toggle plates 5 move back and forth alternately, acting on the moving plate 3 to move the moving plate 3 upward, thereby driving the bracket 12 to move upward to support the arm of the elderly patient; At the same time, the protrusion 9 drives the toggle plate 5 to move along the first sliding groove 10, driving the two toggle plates 5 to move, wherein the pressing effect of one toggle plate 5 on the moving plate 3 is greater than the pressing effect of the other toggle plate 5 on the moving plate 3, thereby causing the rising moving plate 3 to tilt, thereby causing the rising bracket 12 to tilt, so that the back of the elderly patient is separated from the auxiliary seat body 1.

[0021] The limiting parts include a plurality of limiting plates 13 connected and fixed to the movable plate 3, a limiting groove 14 slidingly matched with the limiting plate 13 is opened in the fixed plate 2, and the auxiliary seat body 1 is fixedly connected with a rotating shaft 15 rotatably connected to the fixed plate 2 and the movable plate 3. Through the action of the limiting plates 13 and the limiting grooves 14, it is ensured that the movable plate 3 rotates with the fixed plate 2 without affecting the movement of the movable plate 3 along the direction of the fixed plate 2, so that the movable plate 3 can be lifted and rotated at the same time, so that the bracket 12 lifts the upper limbs of the elderly patient and rotates the upper limb angle of the elderly patient, so that the elderly patient can stand up from the auxiliary seat body 1 easily.

[0022] The reset rod 6 is a U-shaped structure, and a lifting plate 16 is fixedly connected to the middle of the reset rod 6. When the elderly patient stands up from the auxiliary seat body 1, the cylinder 18 is reset by key operation, and at the same time, the lifting plate 16 is moved upward by hand or other operation methods (the elderly patient has stood up at this time, and the weight of the auxiliary seat body 1 is light, which is easy for the elderly patient to operate), so that the reset rod 6 rotates, and the reset rod 6 rotates to contact the toggle plate 5, so that the toggle plate 5 is separated from the moving plate 3; The movable plate 3 automatically moves downward without the action of the toggle plate 5 , and finally, the lifting plate 16 is released, and under the action of the toggle spring, the toggle plate 5 is engaged with the movable plate 3 again.

[0023] The movable part includes a connecting shaft 17 that is slidably matched with the movable plate 4, the connecting shaft 17 is connected and fixed to the edge of the rotating plate 7, a cylinder 18 or an electric telescopic rod is fixedly connected to the auxiliary seat body 1, and a power part is provided between the cylinder 18 and the rotating plate 7; The power member drives the rotating plate 7 to rotate in its original position, thereby driving the connecting shaft 17 to make a circular motion. The connecting shaft 17 can slide along the movable plate 4, so that the connecting shaft 17 in circular motion drives the movable plate 4 to reciprocate at a certain angle with the rotating shaft 15 as the rotation center, thereby driving the protrusion 9 and the toggle plate 5 to reciprocate at a certain angle synchronously.

[0024] The power member includes a gear 19 rotatably connected to the auxiliary seat body 1, the central axis of the gear 19 is fixedly connected to the central axis of the self-rotating plate 7, the telescopic shaft of the cylinder 18 is fixedly connected to a toothed plate 20 meshing with the gear 19, and a buffer is provided between the end of the toothed plate 20 and the sleeve plate 8; The cylinder 18 is started, so that the telescopic shaft of the cylinder 18 is extended, driving the toothed plate 20 to move, and on the one hand, driving the gear 19 to rotate at the original position, so that the self-rotating plate 7 rotates at the original position, and cooperates with the connecting shaft 17 to make the movable plate 4 reciprocate at a certain angle with the rotating shaft 15 as the rotation center, thereby driving the toggle plate 5 to reciprocate at a certain angle, and under the action of the torsion spring, the movable plate 3 moves upward along the fixed plate 2, thereby driving the bracket 12 to move upward, holding the elderly patient's arm, so that the elderly patient's upper body is lifted, and it is convenient for the elderly patient to stand up from the auxiliary chair body 1; On the other hand, the movement of the tooth plate 20 under the action of the buffer makes the sleeve plate 8 move along the movable plate 4, thereby making the protrusion 9 move along the movable plate 4 without affecting the reciprocating rotation of the toggle plate 5 at a certain angle, so that the two toggle plates 5 move, one toggle plate 5 moves away from the movable plate 3, and the other toggle plate 5 approaches the movable plate 3. The two toggle plates 5 are always engaged with the movable plate 3, and the inclination angles of the two toggle plates 5 are inconsistent, thereby pressing the movable plate 3 to tilt, so that the bracket 12 tilts synchronously.

[0025] The buffer member includes a first connecting plate 21 connected and fixed to the tooth plate 20, and a second connecting plate 22 slidably matched with the second sliding groove 11 is rotatably connected to the end of the sleeve plate 8, and a compression spring 23 is hung between the second connecting plate 22 and the first connecting plate 21. When the tooth plate 20 moves with the cylinder 18, it drives the first sleeve plate 8 to move, compresses the compression spring 23, and makes the second connecting plate 22 drive the sleeve plate 8 to move away from the movable plate 4. Due to the rotatable connection relationship between the second connecting plate 22 and the sleeve plate 8, the reciprocating movement of the movable plate 4 does not affect the movement of the second connecting plate 22. The sleeve plate 8 moves away from the movable plate 4, driving the two toggle plates 5 to move synchronously. The protrusion 9 close to the second connecting plate 22 moves away from the movable plate 3, while the protrusion 9 far from the second connecting plate 22 moves close to the movable plate 3. Under the action of the torsion spring, the two toggle plates 5 are clamped on the movable plate 3, but the inclination angles of the two toggle plates 5 are different, and the distances between the movable plate 3 and the two protrusions 9 are different. Under the inclination of the toggle plate 5, the movable plate 3 is gradually tilted, and the fixed plate 2 is synchronously tilted under the action of the limiter, so that the bracket 12 is tilted, and the bracket 12 that rises at the same time is tilted, that is, the upper body of the elderly patient is lifted up and the upper body of the elderly patient is tilted forward, so that the elderly patient's back is detached from the backrest of the auxiliary seat body 1, so that the elderly patient can stand up from the auxiliary seat body 1, and avoid the elderly patient sitting too deep in the auxiliary seat body 1 and cannot stand up from the auxiliary seat body 1.

[0026] The front end of the auxiliary seat body 1 is rotatably connected to a plurality of elliptical wheels 24 arranged in an array for traversing obstacles. The rotation of the elliptical wheels 24 distributed in gaps facilitates traversing obstacles on the ground.
