Referring to fig. 1 to 3, in the present embodiment, the first connecting member 100 is fixed to the side waist of the wearer, and the second connecting member 200 is connected to the hip assembly of the rehabilitation device. Specifically, the first connecting member 100 may be provided with a hook and loop fastener, which is fixed to the waist by hook and loop fastener, or the first connecting member 100 may be provided with a strap, which is tied to the waist by the strap.

The first shaft 400 extends in a first direction, and the second shaft 600 extends in a second direction, where the first direction is a vertical direction and the second direction is a horizontal direction. The second connecting member 200 and the rotating shaft base 300 are respectively provided with a hole extending along the second direction for the second rotating shaft 600 to pass through, so that the rotating shaft base 300 can rotate around the axis of the second rotating shaft 600 relative to the second connecting member 200. The first rotating shaft 400 is fixedly connected with the rotating shaft base 300, the first rotating shaft sleeve 500 is sleeved outside the first rotating shaft 400, the first connecting member 100 is fixedly connected with the first rotating shaft sleeve 500, and the first rotating shaft sleeve 500 can rotate relative to the first rotating shaft 400. When the patient bends sideways, the first connecting piece 100 rotates around the axis of the second rotating shaft 600 relative to the second connecting piece 200; when the patient turns, the first link 100 rotates about the axis of the first rotation shaft 400 with respect to the second link 200. The lateral stooping means stooping toward the side of the body. Compare with conventional connection structure, connection structure in this embodiment has certain degree of freedom, has reduced the degree of difficulty that the person of dress turned round and the side direction is stood down, also more comfortable after the dress.

In addition, the first connecting member 100 and the first rotating shaft sleeve 500 may be integrally connected, which is equivalent to the first connecting member 100 directly sleeved on the first rotating shaft 400. Or, the second rotating shaft 600 may also be fixedly connected to the rotating shaft base 300, and the second connecting member 200 is sleeved on the second rotating shaft 600 and can rotate relative to the axis of the second rotating shaft 600. Alternatively, the first connecting member 100 and the first rotating sleeve 500 may be detachably connected, for example, by a snap-fit connection or a threaded fastener, so as to connect the first rotating sleeve 500 with the first connecting member 100 of different sizes, thereby adapting to different waist sizes of wearers.

Referring to FIG. 4, in another embodiment, the hip and waist connection structure further comprises a third connector 700, wherein the third connector 700 is connected to the hip assembly of the rehabilitation device, and the third connector 700 is rotatably connected to the second connector 200. The axis of the rotation shaft of the first connector 100, the axis of the rotation shaft of the second connector 200, and the axis of the rotation shaft of the third connector 700 are perpendicular to each other. When the rehabilitation device uses the hip and waist connection structure in the embodiment, a wearer can not only turn and bend laterally, but also bend forwards, and the hip and waist connection structure has three freedom degrees of movement, so that the wearer can move more flexibly. The forward stooping herein refers to stooping directly forward of the wearer.

Referring to FIG. 5, in another embodiment, the hip and waist attachment structure further comprises a fourth connector 800, wherein the fourth connector 800 is fixedly connected to the hip assembly of the rehabilitation device. In particular, the fourth connector 800 may be secured to the hip assembly by a threaded fastener, or by a snap-fit connection, or by adhesive. Of course, other known connection methods than the above-mentioned connection methods are also possible. A first rack 710 is arranged on the third connecting piece 700, a second rack 810 is arranged on the fourth connecting piece 800, and the fixing piece 1000 is fixedly connected with the third connecting piece 700 through a threaded fastener. The fourth link 800 extends into a passage between the fixing member 1000 and the third link 700 and is movable in the passage in a first direction. The abutting member 900 is in threaded connection with the fixing member 1000, and after the position of the fourth connecting member 800 in the channel is adjusted, the abutting member 900 is screwed down, so that the end portion of the abutting member is abutted against the fourth connecting member 800, and the fourth connecting member 800 is abutted against the third connecting member 700.

The first rack 710 can be engaged with different regions of the second rack 810, thereby enhancing the locking of the third link 700 and the fourth link 800, so that both can be more stably maintained at the current position. When the distance between the third connecting member 700 and the hip assembly needs to be adjusted, the holding member 900 is loosened, and then the fourth connecting member 800 is pulled in a direction away from the third connecting member 700 until the first rack 710 is separated from the second rack 810. The position of the fourth connecting member 800 is adjusted along the first direction, and after the position is adjusted, the fourth connecting member 800 is moved toward the third connecting member 700 until the second rack 810 is engaged with the first rack 710, and then the abutting member 900 is screwed until abutting against the fourth connecting member 800.

Further, in order to stabilize the meshing relationship between the second rack 810 and the first rack 710, the second rack 810 and the first rack 710 are configured as oblique teeth as shown in fig. 5, and the first rack 710 is inclined upward and the second rack 810 is inclined downward, so that the second rack 810 can be suspended on the first rack 710 and is not easily separated from the first rack 710.

When the hip-waist connection structure of the present embodiment is used for the rehabilitation device, the patient can not only turn, bend sideways and bend forward, but also adjust the distance between the third connection member 700 and the hip assembly, thereby adjusting the distance between the first connection member 100 and the hip assembly. Generally speaking, the distances between the waist and the hip of wearers of different ages and sexes are different, so that the common rehabilitation device on the market is provided with a plurality of specifications to meet the requirements of different people. If the rehabilitation device in the embodiment is worn, the distance between the third connecting member 700 and the hip assembly can be adjusted to adapt to different people, so as to expand the audience range of the rehabilitation device. For manufacturers, the mold opening is not required to be carried out for multiple times according to different sizes, so that the cost can be reduced to a certain extent.

In another embodiment, the fourth connecting member 800 is provided with a plurality of holes arranged along the first direction, and fasteners are provided and threaded to the third connecting member 700 after passing through the holes. The spacing between the third connector 700 and the hip assembly can be adjusted to accommodate different populations by inserting fasteners through different hole locations.

In another embodiment, a rehabilitation device is also provided, and the rehabilitation device comprises the hip and waist connecting structure. After the patient wears the rehabilitation device, the patient can still move to a certain extent, and the patient cannot move inconveniently due to wearing the rehabilitation device.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
