[0024] Reference Figures 1 to 5 As shown, an auxiliary transfer device according to an embodiment of the present invention includes a support component and a transfer component.

[0025] Reference Figure 1 , Figure 4 and Figure 5 As shown, the support assembly includes a first support frame 110 and a second support frame 120 arranged at intervals. Both the first support frame 110 and the second support frame 120 are arranged in an L-shape. The lower ends of the first support frame 110 and the second support frame 120 can be connected to the support base of the external device. For example, the first support frame 110 can be connected to the edge of an object such as a bed or cabinet, thereby providing support for the connection of the transfer assembly.

[0026] Reference Figure 1 , Figure 4 and Figure 5 As shown, the transfer assembly includes a rotating shaft 200, a transmission component, and a pad 300. Both ends of the rotating shaft 200 are rotatably connected to a first support frame 110 and a second support frame 120, respectively. The first support frame 110 and the second support frame 120 allow the rotating shaft 200 to be placed on a horizontal plane, achieving a smooth rotational connection of the rotating shaft 200. The transmission component is configured to drive the rotating shaft 200 to rotate forward or backward relative to the support assembly. The pad 300 can be laid on a bed or other object for a person to lean against, i.e., the pad 300 is used to support the human body. One end of the pad 300 is connected to the rotating shaft 200. Under the driving action of the transmission component, the pad 300 is driven to wind up or unwind around the rotating shaft 200.

[0027] Reference Figure 1 , Figure 4 and Figure 5As shown, when a person lies on the pad 300, the operator can connect the pad 300 to the rotating shaft 200, and then drive the rotating shaft 200 to rotate in the forward direction through the transmission component, so that the edge of the pad 300 gradually rolls up towards the rotating shaft 200. Under the rolling action of the rotating shaft 200, the pad 300 can be dragged, thereby assisting in the transfer of the person on the pad 300 in a lying position, making the transfer of the person more stable, effectively reducing the difficulty of transferring the person in a lying position, and reducing the physical requirements of the operator. After the transfer is completed, the operator can drive the rotating shaft 200 to rotate in the reverse direction through the transmission component, thereby separating the pad 300 from the rotating shaft 200.

[0028] Reference Figure 1 , Figure 4 and Figure 5 As shown, compared to the traditional method that requires two or more operators to lift a person in a lying position for transfer, this auxiliary transfer device only requires one operator to independently and smoothly transfer a person in a lying position. The operation is simpler, reduces the difficulty of transferring a person in a lying position, and reduces the physical requirements on the operator.

[0029] Reference Figure 1 , Figure 3 and Figure 4 As shown, it can be understood that the first support frame 110 has an upwardly open first rotating groove 111, the second support frame 120 has an upwardly open second rotating groove 121, and the rotating shaft 200 is configured to enter and exit the first rotating groove 111 and the second rotating groove 121. When the rotating shaft 200 is located in the first rotating groove 111 and the second rotating groove 121, the rotating shaft 200 is rotatably connected to the support assembly.

[0030] Reference Figure 1 , Figure 3 and Figure 4 As shown, specifically, the first support frame 110 has a first connecting rod and a second connecting rod. The two ends of the first connecting rod are arranged in the horizontal direction, and the two ends of the second connecting rod are arranged in the vertical direction. The lower end of the second connecting rod is connected to one end of the first connecting rod, and the other end of the first connecting rod is used to connect to the support base of the external device. The upper end of the second connecting rod is provided with an upwardly open first rotating groove 111.

[0031] Reference Figure 1 , Figure 3 and Figure 4 As shown, specifically, the second support frame 120 has a third connecting rod and a fourth connecting rod. The two ends of the third connecting rod are arranged in the horizontal direction, and the two ends of the fourth connecting rod are arranged in the vertical direction. The lower end of the fourth connecting rod is connected to one end of the third connecting rod, and the other end of the third connecting rod is used to connect to the support base of the external device. The upper end of the fourth connecting rod is provided with an upward-opening second rotating groove 121.

[0032] Reference Figure 1 , Figure 3 and Figure 4 As shown, the two ends of the rotating shaft 200 are respectively mounted in the first rotating groove 111 and the second rotating groove 121. The first rotating groove 111 and the second rotating groove 121 restrict the rotation of the rotating shaft 200, which can effectively limit the radial displacement of the rotating shaft 200, so as to locate the relative position relationship between the rotating shaft 200 and the support assembly. Under the driving action of the transmission component, the rotating shaft 200 can be wound up or unwound from the pad 300.

[0033] Reference Figure 1 , Figure 3 and Figure 4 As shown, it can be understood that the two ends of the rotating shaft 200 are respectively provided with slots 210, and the first support frame 110 and the second support frame 120 are respectively engaged with the two slots 210 to restrict the rotating shaft 200 from moving along its axial direction.

[0034] Reference Figure 1 , Figure 3 and Figure 4 As shown, specifically, when the rotating shaft 200 is mounted on the first support frame 110 and the second support frame 120, the two slots 210 are respectively engaged with the upper ends of the first support frame 110 and the second support frame 120. Through the abutment between the upper end of the first support frame 110 and the side wall of the slot 210, the rotating shaft 200 can be positioned axially with the first support frame 110 and the second support frame 120. During the process of the transmission component driving the rotating shaft 200 to rotate, the movement of the rotating shaft 200 along its axial direction can be effectively restricted.

[0035] Reference Figure 1 , Figure 3 and Figure 4 As shown, specifically, the bottom surface of the slot 210 is circular, that is, the rotating shaft 200 is cylindrical at the slot 210. Through the contact between the slot 210 and the first support frame 110 or the second support frame 120, the rotational resistance caused by the first support frame 110 and the second support frame 120 to the rotating shaft 200 can be effectively reduced, thereby improving the smoothness of the rotation of the rotating shaft 200.

[0036] Reference Figure 1 , Figure 3 and Figure 4 As shown, it can be understood that a fastener 230 is connected to the rotating shaft 200, and the fastener 230 is detachably connected to the gasket 300. This auxiliary transfer device can be detachably connected to the bed frame, cabinet, or other supporting base.

[0037] Reference Figure 1 , Figure 3 and Figure 4As shown, when the operator needs to transfer a human body in a lying position, the user can connect the auxiliary transfer device to the support base of the external device, and then connect the pad 300 laid at the lower end of the human body to the fastener 230. The fastener 230 is connected to the rotating shaft 200, thus realizing a stable connection between the pad 300 and the rotating shaft 200. Then, the rotating shaft 200 can be driven to rotate in the forward or reverse direction through the transmission component, thereby realizing the winding or unwinding of the pad 300.

[0038] Reference Figure 1 , Figure 3 and Figure 4 As shown, when the human body does not need to be transferred or the human body transfer has been completed, the operator can separate the pad 300 from the buckle 230, and separate the auxiliary transfer device from the external support base, thereby avoiding problems that may hinder other nursing operations or care.

[0039] Reference Figure 1 , Figure 3 and Figure 4 As shown, it can be understood that the rotating shaft 200 has a drive section 220 disposed between the first support frame 110 and the second support frame 120. The radial cross section of the drive section 220 is polygonal. The fastener 230 is fastened to the drive section 220, and the inner circumferential surface of the fastener 230 is adapted to the outer circumferential surface of the drive section 220.

[0040] Reference Figure 1 , Figure 4 and Figure 5 As shown, the radial cross-section of the inner circumference of the buckle 230 is also polygonal. The user can pass the rotating shaft 200 through the buckle 230 and move the buckle 230 to the matching drive section 220. Through the mutual contact and limitation between the inner circumferential surface of the buckle 230 and the outer circumferential surface of the drive section 220, the buckle 230 can rotate with the drive section 220, which can effectively limit the rotation of the buckle 230 relative to the drive section 220. When the rotating shaft 200 rotates, the buckle 230 is connected to the pad 300 to apply a dragging force to the pad 300, so as to assist in the transfer of the human body located on the upper end of the pad 300, making the transfer of the human body in a lying position easier.

[0041] Reference Figure 1 , Figure 4 and Figure 5 As shown, it can be understood that the buckle 230 is fastened to the outer periphery of the drive section 220 of the rotating shaft 200. The buckle 230 is provided with a buckle hole 231. The gasket 300 has a connecting strip 310. The connecting strip 310 includes a first adhesive surface 311 and a second adhesive surface 312. After the first adhesive surface 311 passes through the buckle hole 231, it can be connected to the second adhesive surface 312 to realize the connection between the connecting strip 310 and the buckle 230.

[0042] Reference Figure 1 , Figure 4 and Figure 5 As shown, specifically, the first adhesive surface 311 is one of the male and female sides of the hook and loop fastener, and the second adhesive surface 312 is the other of the male and female sides of the hook and loop fastener. The use of hook and loop fastener connection makes it simpler and more convenient to connect or separate the first adhesive surface 311 and the second adhesive surface 312.

[0043] Reference Figure 1 , Figure 4 and Figure 5 As shown, in use, the operator passes the first adhesive surface 311 of the connecting strap 310 through the buckle hole 231, so that the first adhesive surface 311 and the second adhesive surface 312 are opposite and attached. Through the adhesion of the first adhesive surface 311 and the second adhesive surface 312, the connecting strap 310 passing through the buckle hole 231 is connected in a ring shape to realize the connection between the connecting strap 310 and the buckle 230. Moreover, the use of Velcro connection makes the connection or separation of the first adhesive surface 311 and the second adhesive surface 312 simpler and more convenient.

[0044] Reference Figure 1 , Figure 4 and Figure 5 As shown, specifically, the gasket 300 includes multiple connecting straps 310, and multiple fasteners 230 are connected to the rotating shaft 200 along its length. The connecting straps 310 are correspondingly inserted into the buckle holes 231 of the fasteners 230 and connected to the fasteners 230. Through the multi-point connection, the movement of the gasket 300 can be made more stable.

[0045] It should be understood that in some other embodiments, the fastener 230 can achieve the connection between the connecting strap 310 and the fastener 230 by clamping the connecting strap 310.

[0046] Reference Figure 1 , Figure 4 and Figure 5 As shown, it can be understood that in this embodiment, the transmission component is a rocker arm 400. The rocker arm 400 includes a first sub-rod 410, a second sub-rod 420, and a third sub-rod 430 connected in sequence. The first sub-rod 410 is connected to the rotating shaft 200. The rocker arm 400 has a driving state in which the first sub-rod 410 and the third sub-rod 430 are arranged at an angle to the second sub-rod 420.

[0047] Reference Figure 1 , Figure 4 and Figure 5As shown, during use, the operator can hold the third sub-rod 430 and apply rotational force to the rotating shaft 200 by the angle between the third sub-rod 430 and the second sub-rod 420 and the first sub-rod 410, thereby driving the rotating shaft 200 to rotate. That is, the auxiliary transfer device can be manually driven to rotate, making the operation simpler and more convenient.

[0048] Reference Figure 1 , Figure 4 and Figure 5 As shown, specifically, in order to prevent the rotating shaft 200 from coming out of the first rotating groove 111 and the second rotating groove 121 during rotation, hook grooves 112 are respectively connected to the sides of the first rotating groove 111 and the second rotating groove 121. The user can insert the rotating shaft 200 into the first rotating groove 111 and the second rotating groove 121 from top to bottom. The rotating shaft 200 is configured to be able to enter and exit the hook grooves 112.

[0049] Reference Figure 1 , Figure 4 and Figure 5 As shown, when the operator rotates the shaft 200, the shaft 200 can be locked into the hook groove 112, and the upward movement of the shaft 200 is restricted by the hook groove 112, thereby preventing the shaft 200 from coming out of the first rotating groove 111 or the second rotating groove 121 during rotation.

[0050] It should be understood that in some other embodiments, the transmission component is a forward and reverse motor, which can drive the rotating shaft 200 to rotate in the forward or reverse direction, thereby realizing the winding or unwinding of the gasket 300.

When the first sub-rod 410, the second sub-rod 420, and the third sub-rod 430 are rotated to the same length direction, the user can insert the crank 400 into the cavity 240 to achieve the storage and concealment of the crank 400. Specifically, in the retracted state, the first sub-rod 410 and the second sub-rod 420 are both located in the cavity 240, while the third sub-rod 430 is at least partially inserted into the cavity 240.

[0053] Reference Figure 1 , Figure 4 and Figure 5 As shown, a limiting block is provided at the end of the first sub-rod 410 away from the second sub-rod 420. The radial cross-section of the inner circumferential surface of the cavity 240 is polygonal. The limiting block can abut against the inner wall surface of the cavity 240 to restrict the rotation of the first sub-rod 410 relative to the rotating shaft 200.

[0054] Reference Figure 1 , Figure 4 and Figure 5 As shown, when the operator pulls out the crank handle 400 and switches the crank handle 400 to the unfolded state, the operator can then rotate the crank handle 400 and make the limiting block abut against the inner wall of the cavity 240, thereby causing the crank handle 400 to drive the rotating shaft 200 to rotate synchronously, thereby realizing the winding or unwinding of the gasket 300.

A transmission component is configured to drive the rotating shaft 200 to rotate forward or backward relative to the support assembly. A pad 300 can be used to support the human body, and one end of the pad 300 is connected to the rotating shaft 200. When the human body lies on the pad 300, the operator can connect the pad 300 to the rotating shaft 200, and then, through the transmission... The component drives the rotating shaft 200 to rotate in the forward direction, so that the edge of the pad 300 gradually curls up. Under the curling action of the rotating shaft 200, the pad 300 can be dragged, thereby assisting in the transfer of the human body on the pad 300 in a lying position. This makes the transfer of the human body more stable, effectively reducing the difficulty of transferring the human body in a lying position and reducing the physical requirements of the operator. After the transfer is completed, the operator can drive the rotating shaft 200 to rotate in the reverse direction through the transmission component, thereby separating the pad 300 from the rotating shaft 200.

A first support frame 110 has a first insertion end, and a second support frame 120 has a second insertion end. Both the first and second insertion ends are square tubes, allowing them to be inserted into the two square holes respectively. This facilitates the connection between the first and second support frames 110 and 120 and the bed frame 500, keeps the first and second support frames 110 and 120 parallel to each other, and effectively restricts the rotation of the first and second support frames 110 and 120 relative to the bed frame 500.
