The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

The first embodiment is as follows:

as shown in fig. 1-3, an auxiliary shifting device for a bed comprises two mounting holders 1 and a rotating shaft 2, wherein the two mounting holders 1 are respectively fixed on two sides of the bed 3, a human body shifting device 4 is arranged on the bed 3, the human body shifting device 4 is used for shifting the body of a person walking on the bed 3, and the human body shifting device 4 is fixedly connected with the rotating shaft 2 and can move along with the rotation of the rotating shaft 2. Two sides of installation fixing base 1 are equipped with first casing 5 and second casing 6 respectively, and first casing 5 and second casing 6 are equipped with mounting hole 7 through screw and 1 fixed connection of installation fixing base respectively on the installation fixing base 1, and first casing 5 and mounting hole 7 are passed respectively to pivot 2 to with 1 spacing connection of installation fixing base. The cover is equipped with bearing 8 in pivot 2, and the outer lane of bearing 8 passes through the bolt and fixes with installation fixing base 1 is spacing, bearing 8's inner circle and 2 interference fit of pivot, and bearing 8 passes in the mounting hole 7, and bearing 8's inner circle protrusion installation fixing base 1's side.

One end of the rotating shaft 2 is fixedly provided with an adjusting connecting rod 9, the adjusting connecting rod 9 penetrates through the second shell 6, the adjusting connecting rod 9 is overlapped with the central axis of the rotating shaft 2, and the other end of the adjusting connecting rod 9 is provided with a ratchet wrench 10 locked in one way; in other embodiments, other mechanical components with rotation function can be arranged on the adjusting connecting rod 9. The ratchet wrench 10 is wrenched to rotate, the adjusting connecting rod 9 can be driven to rotate, and the adjusting connecting rod 9 drives the rotating shaft 2 to rotate, so that the human body shifting device 4 is driven to move, and the human body shifting is completed.

In order to prevent the ratchet wrench 10 from resetting and rotating reversely, the rotating shaft 2 rotates along with the ratchet wrench, and the mounting and fixing seat 1 is provided with a damping device for limiting the rotation of the rotating shaft 2; the damping device comprises a damping fin 11 and a spring pressing sheet 12, the damping fin 11 and the spring pressing sheet 12 are respectively sleeved on the rotating shaft 2, and two side surfaces of the damping fin 11 are respectively abutted against the end surface of the inner ring of the bearing 8 and the spring pressing sheet 12; spring preforming 12 passes through preforming bolt 13 and the spacing connection of installation fixing base 1, is equipped with spring 14 on the preforming bolt 13, and the one end of spring 14 and the one side butt that damping fin 11 was kept away from to spring preforming 12. In this embodiment, the number of the tablet bolts 13 and the springs 14 is two, and it is obvious that the number of the tablet bolts 13 and the springs 14 may be more than two in other embodiments. After the assembly is finished, the spring pressing sheet 12 abuts against the damping sheet 11, the damping sheet 11 abuts against the inner ring of the bearing 8, and under the action of the elastic force of the spring 14, friction force is generated between the inner ring of the bearing 8 and the damping sheet 11; when the ratchet wrench 10 is reset and rotates reversely, the friction force is generated to prevent the rotating shaft 2 from rotating along with the ratchet wrench 10; when the ratchet wrench 10 rotates forward, as long as the applied acting force is greater than the friction force between the inner ring of the bearing 8 and the damping fin 11, the rotating shaft 2 rotates along with the ratchet wrench 10, so that the human body can be displaced.

The human body displacement device 4 comprises a drawstring 15 and a fixing band 16, wherein the drawstring 15 is a woven band, and the fixing band 16 is an elastic band with elasticity. Both ends of stretching strap 15 respectively with fixed

band
