Description

Technical Field

[0001] The utility model belongs to the technical field of rehabilitation auxiliary equipment, in particular to a lower limb rehabilitation walker. Background Art

[0002] The aging of our country is increasing. Under the background of the large aging population in our country, the emergence and development of the aging problem are becoming increasingly severe, resulting in the increasing proportion of empty nests, disabled and semi-disabled groups of the elderly. Some elderly people have difficulty walking, poor health, or injuries to the parts below the legs, which leads to difficulty walking, or patients who have just recovered from illness are not suitable for walking activities. Although the medical level of the country is gradually improving, there are still many people with inconvenience in legs and feet, and the inconvenience in legs and feet also brings deep troubles to people. In order to help the elderly with inconvenience in walking to recover, the equipment usually used is a walking frame, which mainly plays the role of supporting the body, including a support frame symmetrically arranged on both sides of the walking frame, a rear back cross bar for connecting two handrails, and a top cross bar connecting the tops of the two support frames. Many existing walking frames are similar to frame-type crutches. When assisting exercise, it is necessary to lift it off the ground as a whole or in part to achieve walking movement, which becomes a burden for the elderly with insufficient arm strength. Secondly, when the walking frame is lifted, the walking frame does not contact the ground, and the walking frame has no auxiliary support function. In order to solve the above technical problems, this application document provides a lower limb rehabilitation walker. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:

[0028] See also Figure 1-7 As shown, the utility model is a lower limb rehabilitation walker, comprising two symmetrically arranged support frames 1, and the support frames 1 are inverted U-shaped tubes. A downward-pressed self-locking bottom wheel 2 is respectively installed at both ends of the support frames 1. At least two pairs of angle-limiting swivel seats 3 are symmetrically installed on the relative inner side walls of the front ends of the two support frames 1, and a connecting rod 4 is installed on each pair of angle-limiting swivel seats 3. The support frame 1 is a U-shaped tube structure. A row of round through holes 11 are respectively opened in the lower half of the vertical rods of the support frame 1. A sheath 12 is installed in the middle of the horizontal rod of the support frame 1.

[0029] The bottom wheel 2 specifically includes a roller base 21 , a connecting seat 22 , and a spring 23 .

[0030] The roller base 21 includes a U-shaped channel frame 211 with an opening downward. A roller 212 is installed at each end of the U-shaped channel frame 211. A rectangular through hole 213 is provided at the center of the upper end of the U-shaped channel frame 211. Two internally threaded tubes 214 are fixed at each end of the rectangular through hole 213 at the upper end of the U-shaped channel frame 211.

[0031] The connecting seat 22 includes a rectangular plug 221 that matches the rectangular through hole 213. A circular arc groove 222 that matches the outer contour of the roller 212 is respectively provided at the two corners of the lower end of the rectangular plug 221. A flange plate 223 that slidably matches the outer walls of the two internally threaded tubes 214 is fixed to the upper end of the rectangular plug 221. The spring 23 is sleeved on the internally threaded tube 214, and the spring 23 is placed below the flange plate 223. A cap bolt 24 is threadedly connected to the upper end of the internally threaded tube 214. A cylindrical rod 224 that plugs and matches with the lower end of the support frame 1 is fixed to the middle of the upper end of the flange plate 223. A spring pin 225 that matches the round through hole 11 is inlaid and installed on the cylindrical rod 224. The circular arc groove 222 has a plurality of axially arranged anti-slip grooves 226 along the arc surface.

[0032] The support frame 1 and the bottom wheel 2 are inserted and fixed in the round through hole 11 at a suitable height position through the spring pin 225, so that the lower limb rehabilitation walker can be adjusted to a suitable height for use by people of different heights.

[0033] like Figure 1As shown, two support frames 1, four bottom wheels 2, two pairs of angle-limiting swivel seats 3 and connecting rods 4 constitute a simple and reliable walker. When moving the lower limbs, two hands apply force to press down the two support frames 1 at the same time, and the connecting seat 22 on the bottom wheel 2 presses down the arc groove 222 at the lower end of the rectangular plug 221 to be stuck on the outside of the roller 212 to limit the rotation of the roller 212, and the entire walker is in a stable supporting state on the ground. When the lower limbs do not move, the pressure of the two hands is reduced, and under the action of the spring 23, the arc groove 222 is freed from the restriction on the roller 212, and the arm applies force forward to the bottom wheel 2 that rolls forward, and the entire walker can be pushed forward without lifting the walker. The movement process of the walker to assist lower limb rehabilitation exercise is smooth.

[0034] Among them, the angle-limiting swivel seat 3 includes an inner circular groove body 31 welded and fixed to the support frame 1. A coaxially arranged single-end screw 32 is fixed to the inner bottom surface of the inner circular groove body 31. A fan-shaped notch 33 is provided at the outer wall of the inner circular groove body 31 away from the support frame 1. The connecting rod 4 includes a straight rod 41 with adjustable length. A round sleeve 42 sleeved on the single-end screw 32 is fixed at both ends of the straight rod 41. The length of the round sleeve 42 is half the length of the single-end screw 32. A cap nut 5 is installed at the screw end of the single-end screw 32.

[0035] The two support frames 1 of the utility model are connected by two pairs of angle-limiting swivel seats 3 and connecting rods 4, which facilitate the unilateral independent forward driving of the walker, and facilitate the unilateral support frame 1 to move forward alternately with the same-side leg during lower limb exercise, so that the lower limb exercise walking aid is flexible and comfortable.
