Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

Referring to fig. 1-3, the utility model provides a recovered capable ware of helping of low limbs, including two similar arch support frame 1, these two support frame 1 set up in helping capable ware both sides, and two support frame 1 lean on the anterior one-tenth steel pipe that inclines to arrange of helping capable ware to be used for treating that recovered personnel is hand in order to support the health walking, are connected with on two steel pipe upper portions at two support frame 1's rear portion and lean against horizontal pole 2. Optionally, the backrest cross bar 2 is arranged with a certain bending amplitude for abutting against the back of the user. Further, a top cross bar 6 is connected to the top of the two supporting frames 1, and one possible function of the top cross bar 6 is to strengthen the frame structure.

In a possible embodiment, with reference to fig. 1, the two supporting skeletons 1 are identical in structure, and a skeleton rail 11 is provided in the middle of the supporting skeletons 1. A seat plate 5 is arranged between the two framework cross rods 11, and the addition of the seat plate 5 can enable the walking aid to be used as a wheelchair, so that a user can conveniently take a seat for rest in the rehabilitation training process.

In a possible embodiment, the bottom of the seat plate 5 is provided with mounting rods 51, in this embodiment the mounting rods 51 are provided in two and parallel arrangements. Correspondingly, the two framework cross bars 11 are provided with mounting seats 7 for fixing the mounting rods 51, optionally, the mounting seats 7 comprise clamping bands clamped on the framework cross bars 11 and mounting sleeves arranged on the clamping bands, and two ends of the mounting rods 51 are respectively fixed on one mounting sleeve. That is, the seat plate 5 is removably mounted to the walker and the mounting 7 is directly removed to remove the seat plate 5 when not needed.

Referring to fig. 1, the supporting framework 1 includes two supporting legs, the two supporting frameworks 1 include four supporting legs, a telescopic mechanism 3 is connected to the lower portion of each of the four supporting legs, and a traveling device 4 is installed below the telescopic mechanism 3. Wherein, telescopic machanism 3 is used for realizing helping the lift of capable ware, when four telescopic machanism 3 all synchronous start-up same height, can realize helping the regulation of capable ware overall height to satisfy different height users' high demand. Alternatively, when only the two telescoping mechanisms 3 at the back end are extended, the seat plate 5 can be raised as a whole and tilted at an angle to assist the user in rising from the seat plate 5.

Optionally, this telescopic machanism 3 adopts electric putter, and electric putter's telescopic link top and the bottom fixed connection of stabilizer blade, optionally, the telescopic link top passes through the bolt with the bottom of stabilizer blade and is connected.

With continued reference to FIG. 1, a walking device 4 is attached to the bottom of the telescoping mechanism 3, the walking device 4 facilitating walking of the walker.

Referring to fig. 4, the traveling device 4 includes a brake frame 41, a spring 42, a traveling wheel 43, and a limit screw 44. Wherein, optionally, the brake frame 41 is arranged like an "F" and includes a first horizontal plate 411 arranged on the top, a second horizontal plate 412 arranged in parallel at the bottom of the first horizontal plate 411, and one end of each of the first horizontal plate 411 and the second horizontal plate 412 is connected to the vertical plate 413. Optionally, a limit screw 44 is fixedly disposed on the top surface of the support of the road wheel 43, and the limit screw 44 penetrates through the first horizontal plate 411 and the second horizontal plate 412. A spring 42 is arranged on the section of the limit screw 44 between the top surface of the traveling wheel 43 support and the second transverse plate 412, and two ends of the spring 42 respectively abut against the top surface of the traveling wheel 43 support and the bottom surface of the second transverse plate 412. An adjusting nut 45 is arranged on the section of the limit screw 44 between the first horizontal plate 411 and the second horizontal plate 412.

For example, when the walking device 4 is used as a chair, the user sits on the seat plate 5, so that the second cross plate 412 presses the spring 42 downwards, the brake frame 41 moves downwards as a whole, the vertical plate 413 moves downwards and contacts with the ground to generate a large friction force, and the walking wheels 43 cannot move, so that the brake frame 41 plays a role in braking, that is, when the walking aid is used as a chair, the walking safety is improved by limiting the movement of the walking wheels 43. Wherein, the riser 413 is a set height from the ground in normal use, and the height between the riser and the ground can be adjusted by rotating the adjusting nut 45 to adjust the compression degree of the spring 42, so as to adjust the height of the brake frame 41 from the ground.

In one possible embodiment, the walker constitutes a pushable wheelchair when the extension and retraction of the spring 42 is adjusted so that the riser 413 of the brake frame 41 does not come into contact with the ground when the spring 42 is compressed, i.e. the brake frame 41 does not have a braking function. When the risers 413 are accessible to the ground, the walker constitutes a non-pushable seat.

The walker in this embodiment is also collapsible for easy transport, and in particular, with reference to figures 2 and 4, the top cross bar 6 is formed by a first tube section 61 and a second tube section 62 connected together, wherein the second tube section 61 is receivable within the first tube section 61, and wherein a resilient button 63 is provided at one end of the second tube section 62 and, correspondingly, a limiting hole is provided at the corresponding end of the first tube section 61. When the resilient button 63 is pressed and the first tube section 61 and the second tube section 62 are moved relative to each other, the two rotatable support shells 1 are now rotated about the axes a and b, respectively, to fold into the walker. Wherein, one end of the first pipe section 61 and one end of the second pipe section 62 are respectively hinged on the two supporting frameworks 1, and the hinged positions are the positions of the axes a and b. In addition, two ends of the backrest cross rod 2 are connected with sleeves 21, and the two sleeves 21 are respectively sleeved on the back steel pipe of the supporting framework 1. When the support frame 1 is folded inwards, the back steel tube of the support frame 1 can rotate in the sleeve 21. Thus, the support frame 1 can be folded quickly when the elastic button 63 is pressed.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
