Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of walking aids, and particularly relates to an anti-falling walking aid. BACKGROUND

[0002] A walking aid is a device that helps the elderly walk and can prevent the elderly from falling. Existing walking aids are mostly divided into two types: one is a walking aid with a pulley, and the other is a walking aid without a pulley.

[0003] Chinese patent publication No. CN106109187A discloses an anti-falling intelligent walking aid for the elderly, which comprises a support rod, a handrail, reinforcing ribs, an extension rod, a CPU, and a power supply. The handrail, reinforcing ribs, and extension rod are arranged between the support rods. The extension rod and the electric extension rod are provided, the height of the support rod and the distance between the support rod and the handrail can be freely adjusted, and thus the walking aid is most convenient for the elderly to walk.

[0004] 1. The above-mentioned walking aid lacks an anti-falling component, and falling may occur during use, for example, the walking aid may roll over or turn over forward and backward, thereby reducing the safety performance of the walking aid.

[0005] 2. Although the walking aid with a moving wheel can help the elderly walk more easily and conveniently, the pulley of the walking aid with a pulley may slide when the elderly walk on a slope or a wet road, which may cause the elderly to fail to keep up with the speed of the walking aid. Meanwhile, the center of gravity of the whole body of the elderly may be pressed on the walking aid when the elderly walk, and the walking aid with a pulley may cause the elderly to fall. The walking aid is usually fixedly connected with the moving wheel, and the height of the moving wheel cannot be adjusted to meet the use requirements in different scenes. SUMMARY

[0006] To solve the problems in the above background, the utility model provides an anti-falling walking aid. The rotating lifting adjusting screw rod drives the lifting plate to move up and down, realizes the lifting and separation of the walking wheel from the ground, and is applied to walking on flat or uneven roads. The anti-falling guard plate in the fan-shaped structure is in contact with the ground, and the handlebar controls the movement of the walking aid frame. The anti-falling guard plate prevents the walking aid frame from tilting, avoids the falling of the walking aid, and improves the safety performance of the walking aid.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an anti-falling walking aid, which comprises a walking aid frame, a push rod connected to the upper front end of the walking aid frame, a handlebar connected to the upper sides of the walking aid frame, a reinforcing support rod connected to the middle of the two sides of the walking aid frame, a lifting adjusting screw rod connected to the bottom end of the walking aid frame and arranged on the reinforcing support rod, a lifting adjusting mechanism arranged on the lifting adjusting screw rod, and a walking wheel connected to the bottom of the lifting adjusting mechanism. An anti-falling guard plate is installed on the outer side of the bottom end of the walking aid frame.

[0008] As a preferred scheme, the liftable adjusting mechanism comprises a lifting plate and a supporting column, the middle part of the lifting plate is arranged on a lifting adjusting screw through a screw block, the two ends of the lifting plate slide on a sliding groove on the inner wall of the walker frame body through limiting sliding blocks, the bottom of the two ends of the lifting plate is connected with the supporting column, and the lower end of the supporting column is connected with a walking wheel through a limiting guide hole at the bottom of the walker frame body.

[0009] As a preferred scheme, the anti-falling guard plate is designed in a fan-shaped structure and symmetrically arranged at the bottom of the walker frame body.

[0010] As a preferred scheme, the top end of the lifting adjusting screw is connected with an adjusting disc; the adjusting disc rotates to drive the lifting adjusting screw to move the lifting plate up and down, and the lifting plate drives the walking wheel to move up and down through the supporting column.

[0011] As a preferred scheme, a reversible seat plate is connected to the reinforcing support rod at the front end of the walker frame body through a damping rotating shaft.

[0012] As a preferred scheme, a plurality of anti-falling guard plates are arranged, and the bottom of the anti-falling guard plate is provided with an anti-skid pad.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] When walking on uneven road, the walking wheel is used for auxiliary walking, and the walker is prone to overturning, therefore, the walking wheel is separated from the ground by reversing the lifting adjusting screw and driving the lifting plate, the anti-falling guard plate at the bottom of the walker frame body contacts the ground, and the old person can control the movement of the walker frame body through the handlebar, so that the phenomenon of falling and turning over is avoided, and the safety performance of the walker is improved.

[0015] When the old person is tired of walking, the seat plate is rotated to be in a horizontal state, and the old person can sit on the seat plate to rest, the anti-falling guard plate is symmetrically arranged at the bottom of the walker frame body in a fan-shaped structure and expands outward, the anti-falling guard plate contacts the ground, and the movement or overturning of the walker frame body is prevented after the old person sits on the seat plate.

[0016] On a relatively flat road, the lifting adjusting screw is rotated by the adjusting disc to drive the lifting plate to move up and down, and the lifting plate drives the walking wheel to move up and down through the supporting column and contacts the ground, so that the old person can walk by pushing the push rod.
