DETAILED DESCRIPTION

[0021] like Figure 1-7 As shown, a back-carrying transfer lift includes a lifting mechanism. The lifting mechanism comprises a lower bracket 3 and an upper bracket 6. A first push rod 4 is provided on one side of the lower bracket 3. A first hinged plate 8 is provided on the upper portion of the lower bracket 3. The upper end of the first push rod 4 is hingedly connected to the lower end of the first hinged plate 8, which is secured to the lower bracket 3 via a first connecting rod 9. The lower end of the first push rod 4 is hingedly connected to the front of the lift's base plate 1. A connecting plate 2 is secured in the middle of the base plate 1 and hingedly connected to the lower rear end of the lower bracket 3.

[0022] The lower front end of the lower bracket 3 is hinged to the lower end of the second push rod 5, the upper end of which is hinged to the second hinge plate 10. A second connecting rod 12 extends through the middle of the second hinge plate 10, which passes through the middle of the third hinge plate 11. The lower end of the third hinge plate 11 is hinged to the front end of the third push rod 7, and the rear end of the third push rod 7 is hinged to the middle of the back of the chest support plate 14. The second connecting rod 12 is fixed to the front end of the upper bracket 6, and the lower end of the middle of the upper bracket 6 is hinged to the top end of the lower bracket 3 via a hinge shaft. A hinge shaft is provided on the back of the chest support plate 14, and the rear end of the upper bracket 6 is hinged to the hinge shaft on the back of the chest support plate 14.

[0023] Among them, the upper end of the second push rod 5 is hinged to the front lower end of the second hinge piece 10, the second connecting rod 12 passes through the rear lower end of the second hinge piece 10 and the middle of the third hinge piece 11, and the upper end of the second hinge piece 10 and the upper end of the third hinge piece 11 are both provided with an arc-shaped limiting notch, and a third connecting rod 13 is passed through the arc-shaped limiting notch. The third connecting rod 13 is parallel to the second connecting rod 12, and the end of the third connecting rod 13 is fixed to the front end of the upper bracket 6.

[0024] The second hinge piece 10 , the third hinge piece 11 , the second connecting rod 12 and the third connecting rod 13 together constitute a fixed connection mechanism.

[0025] The number of the lower bracket 3 and the upper bracket 6 are both two. The left and right ends of the second connecting rod 12 and the third connecting rod 13 are connected to the left and right upper brackets 6 respectively.

[0026] There are two connecting pieces 2 , and a hinge shaft is provided between the two connecting pieces 2 and the two lower brackets 3 .

[0027] When the back-carrying transfer machine is in use, the state of the transfer machine is as follows: Figure 7 As shown, the first push rod 4 and the second push rod 5 are both in an extended state, so that the lower bracket 3 is erected and the upper bracket 6 is in a horizontal state. At the same time, the third push rod 7 is in a retracted state, thereby driving the chest support board to fall. At this time, it is only necessary to help the user stand up and turn around to sit next to the bed or the seat, push the shift lift over, put the user's feet on the bottom plate of the shift lift, and let the user's chest fit tightly against the chest support shell of the shift lift. Then, the first push rod 4 and the second push rod 5 are both retracted, the lower bracket 3 tilts forward, and the upper bracket 6 tilts upward (assuming that the user is facing the front and the user is facing the back); the third push rod 7 is extended, and the chest support board is lifted. At this time, the user becomes a squatting position, with the upper body lying on the chest support shell, as shown in FIG. Figure 1 shown.

[0028] The embodiments described above are merely descriptions of preferred implementation methods of the present invention, and are not intended to limit the scope of the present invention. They should not be understood as limitations on the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
