Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1 to 6, an auxiliary device for an old person to go up and down stairs includes:

the sliding seat 2, the lower side of the sliding seat 2 is provided with a sliding opening 9 matched with the side lever 1, wherein the side lever 1 is a longitudinal handrail of a stair, two side walls of the sliding opening 9 are provided with rotating grooves, a rotating wheel 7 is rotationally arranged in the rotating grooves, the upper end of the rotating wheel 7 is provided with a conical shaft 11, the conical shaft 11 is of a structure with a small upper part and a large lower part, the sliding seat 2 is also internally provided with a pressure cavity 10, two ends of the pressure cavity 10 are hermetically and slidably provided with piston blocks 13, the piston blocks 13 can axially slide along the rotating wheel 7, the upper end of each piston block 13 is fixedly connected with the top wall of the pressure cavity 10 through a spring 14, the lower end of each piston block 13 is fixedly connected with a conical cover 12 matched with the conical shaft 11;

the device comprises a fixed rod 3 and a movable rod 4, wherein one end of the fixed rod 3 is fixedly connected with a sliding seat 2, the other end of the fixed rod 3 is hinged with the movable rod 4, the rotatable direction of the fixed rod is the same as that of a rotating wheel 7, a first air bag 5 is also arranged between the fixed rod 3 and the movable rod 4, the fixed rod 3 and the movable rod 4 can extrude the first air bag 5 when rotating relative to the fixed rod 3, and the first air bag 5 is communicated with a pressure cavity 10 through an air duct 8;

in the embodiment applying the technical scheme, before the user uses the sliding seat 2, the sliding seat 2 is mounted on the side rod 1 through the sliding opening 9, specifically, the side rod 1 is positioned in the sliding opening 9, the rotating wheels 7 at two sides of the sliding opening 9 are in rolling contact with the side rod 1, that is, when the sliding seat 2 slides on the side rod 1, the rotating wheels 7 can rotate on the surface of the side rod 1 due to friction force to enable the first air bag 5 to face to one side direction of going down stairs, in an initial state, the movable rod 4 and the fixed rod 3 are positioned in the same straight line and perpendicular to the side rod 1, that is, the side rod is positioned in front of the user in the transverse direction, and at this time, the conical;

when a user uses the device to go upstairs, one hand holds the fixed rod 3, and the other hand holds the movable rod 4; when the device needs to be pushed upwards, the sliding seat 2 can be directly pushed upwards for a certain distance along the side rod 1 by holding the force of the fixed rod 3; when needing to go upstairs by virtue of force, a hand holding the movable rod 4 firstly exerts force downwards to enable the movable rod 4 to rotate for a certain angle relative to the fixed rod 3, at the moment, the air bag is compressed, gas in the air bag is squeezed into the pressure cavity 10, so that the piston block 13 is pushed to slide downwards, the conical cover 12 is enabled to move towards one side close to the conical shaft 11 and finally abut against the conical shaft 11, at the moment, the inner wall of the conical cover 12 is in close contact with the outer wall of the conical shaft 11, so that the rotation of the conical shaft 11 is limited, and the rotating wheel 7 cannot rotate; the user exerts force with both hands again, at this moment because the rotating wheel 7 can't rotate, and there is great friction between side lever 1 and the rotating wheel 7, make the slide carriage 2 unable to slip relative to side lever 1, the whole apparatus will not move downward, so the user can ride on a step with the help of strength; after the device is stably ascended on a step, the hand holding the movable rod 4 is released, after the movable rod 4 is reset, the hand holding the fixed rod 3 exerts force again to push the device upwards for a certain distance, and the device can slowly climb the stairs in a relaying manner by repeating the above operations;

stair operation is similar with going up the stair down, under the steady state of standing, promote slide 2 certain distance that slides down through dead lever 3, then promote movable rod 4 and make it rotate certain angle, and then 2 positions of lockable slide, then walk a step downwards again, when the unstable trend of toppling over forward of user's focus, because the device transversely sets up in user the place ahead, have ascending holding power, the user also can borrow power adjustment focus, the steady back of lower step station, operation more than the repetition again.

In the invention, the fixed rod 3 and the movable rod 4 are transversely arranged in front of the body of a user, when in use, one hand holds the fixed rod 3, and the other hand holds the movable rod 4, so that the whole body of the user faces forwards, and the user can exert force and walk conveniently.

In the preferred technical scheme in the embodiment, the inner wall of the conical cover 12 and the outer wall of the conical shaft 11 are both subjected to frosting treatment; therefore, the conical cover 12 can more stably limit the rotation of the conical shaft 11; according to a further preferable technical scheme, the surface of the rotating wheel 7 is sleeved with a rubber anti-slip pad, and the friction force between the rotating wheel 7 and the side rod 1 is increased by arranging the anti-slip pad; it is further preferred that the surface of the rotating wheel 7 is provided with a tooth, the side wall of the side lever 1 is also provided with a tooth, and the rotating wheel 7 is meshed and connected with the side lever 1, so that the slipping phenomenon can be completely avoided.

According to the optional technical scheme in the embodiment, a first handheld portion 15 is arranged at the end portion, far away from the fixed rod 3, of the movable rod 4, a second handheld portion 16 is arranged in the middle of the fixed rod 3, and anti-skidding sleeves are sleeved on the two handheld portions; the anti-slip sleeve can prevent a user from slipping, and the first handheld part 15 is arranged at the end part of the movable rod 4 far away from the fixed rod 3, so that the movable rod 4 can be more easily rotated by the user when the user exerts force; according to a further preferable technical scheme, a second air bag 6 is further arranged between the fixed rod 3 and the movable rod 4, an air hole 17 is formed in the antiskid sleeve, air cavities 18 are formed in the fixed rod 3 and the movable rod 4, and the air cavities 18 are used for communicating the second air bag 6 with the air hole 17; specifically, in the use process, the second air bag 6 continuously stretches so as to cause air flow in the air hole 17, so that the sweat on the anti-slip sleeve can be accelerated to be gasified, and the probability of occurrence of slipping caused by sweating of the palm of the user is reduced.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the invention.
