Detailed Description

To facilitate an understanding of the utility model, the utility model is described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1 to 4, in the present embodiment, a walking aid for assisting in ascending and descending stairs comprises a handrail frame 1, a front foot frame 2, two rear foot tubes 3 and an adjusting assembly, wherein the front foot frame 2 is arranged at the front end of the handrail frame 1. The front foot rest 2 comprises two front foot tubes 21 and a connecting tube 22 which are integrally formed, and the two front foot tubes 21 are symmetrically arranged at two ends of the connecting tube 22. The two rear foot tubes 3 are respectively and fixedly connected with the two sides of the rear end of the handrail frame 1. Two slide bars 11 are symmetrically arranged at the front end of the armrest frame 1, wherein a plurality of positioning holes 111 arranged in order along the length direction of each slide bar 11 are preset in each slide bar 11. The two front leg tubes 21 are respectively sleeved on the two slide bars 11 in a sliding manner, so that the two slide bars 11 can respectively slide up and down in a reciprocating manner along the length direction of the two front leg tubes 21, and the device can be adjusted to be lifted or lowered. Each of the front legs 21 is formed with a rod mounting portion 23, each rod mounting portion 23 is preset with an inner cavity 231 communicated to the inside of the front leg 21, and the inner cavity 231 of each rod mounting portion 23 is embedded with a spring rod 26, wherein a spring portion of the spring rod 26 is abutted against the bottom of the inner cavity 231.

Referring to fig. 5 or 6, in the present embodiment, the bottom of each front leg tube 21 and the bottom of each rear leg tube 3 are formed with a hinge portion 24 having a spherical structure, and each hinge portion 24 has a foot hinge block 25, so that when the walker contacts the ground in an inclined state, the foot hinge block 25 can be attached to the ground, and the walker is not easy to slip due to the fact that the bottom of the walker does not completely attach to the ground when contacting the ground.

Referring to fig. 1 to 4, in the present embodiment, the adjusting assembly includes two connecting wires 41, two handles 42 and two limiting members 43, wherein the two limiting members 43 are respectively and fixedly installed at two sides of the armrest frame 1, and the two handles 42 are respectively hinged to the two limiting members 43, so that the two handles 42 can both rotate up and down in a reciprocating manner. Each limiting part 43 is preset with a first through hole; each lever mounting portion 23 is predisposed with a second through hole. One end of each connecting wire 41 passes through a first through hole and is fixedly connected to a handle 42; the other end of each connection line 41 passes through a second through hole and is fixedly connected to the head end of the spring rod 26. The spring rod 26 is elastically contracted by rotating the handle 42 upward to draw the connection wire 41, so that the connection wire 41 pulls the head end portion of the spring rod 26; by releasing the handle 42, the handle 42 is rotated downward, so that the connection wire 41 is pulled by the external force, thereby elastically restoring the spring lever 26.

In this embodiment, when the walking aid is used to assist walking, the spring rod 26 is in an elastic recovery state, the opening of the inner cavity 231 is aligned with one of the positioning holes 111, and the spring rod 26 extends from the inner cavity 231 to be clamped in the positioning hole 111, so that the front leg tube 21 and the sliding rod 11 are fixed to each other, and the front end of the walking aid is not adjustable. When the walking aid needs to be adjusted, the two handles 42 are rotated upwards at the same time, so that the two spring rods 26 are elastically contracted, at the moment, each spring rod 26 is completely retracted into one inner cavity 231 and is not clamped in the positioning hole 111, the two sliding rods 11 can respectively slide up and down along the two front foot tubes 21 in a reciprocating manner, and the front end of the walking aid can be adjusted. After the adjustment of the front end of the walking aid is completed, the two handles 42 are released, the two spring rods 26 are elastically restored, and each spring rod 26 is correspondingly clamped in the other positioning hole 111, so that the two front foot tubes 21 and the two sliding rods 11 are respectively fixed with each other again. When the walking aid is used for assisting in going upstairs or on a slope, the front end of the walking aid needs to be adjusted to descend; when the walking aid is used for assisting in going down stairs or slopes, the front end of the walking aid needs to be lifted and adjusted.

The above-described embodiments are merely preferred embodiments of the present invention, which is not intended to limit the present invention in any way. Those skilled in the art can make many changes, modifications, and equivalents to the embodiments of the utility model without departing from the scope of the utility model as set forth in the claims below.
