With the increase of the age, the flexibility of the human body is gradually reduced, the old is difficult to lift the legs, and the old is difficult to walk up stairs if the old is not helped by the other people. Meanwhile, since the old people mostly suffer from cardiovascular and cerebrovascular diseases such as hypertension, hidden dangers such as insufficient blood supply and the like easily occur when climbing stairs for a long time, and when the old people encounter multi-layer stairs, the old people are particularly difficult, so that a device is required to be designed, and the difficulty of the old people to climb stairs is solved.

Disclosure of Invention

The utility model aims to provide a stair climbing leg lifting auxiliary device which is used for solving the problem that the old is difficult to climb stairs.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an auxiliary device for lifting legs of a upstairs comprises a stand column, a leg lifting plate, a driving motor and a stay wire;

the upright post main body is a cylindrical rod, and the top end of the cylindrical rod is provided with a handle;

the driving motor is fixedly arranged below the upright post handle, a rotating disk is arranged on an output shaft of the driving motor, and is fixedly connected with one end of a stay wire and used for drawing in the stay wire when the driving motor rotates;

the leg lifting plate body is a flat plate, a sliding bearing is arranged on one side of the flat plate, the bearing is matched with a cylindrical rod of the upright post to realize sliding on the cylindrical rod, and the upper end of the leg lifting plate is fixedly connected with the other end of the stay wire.

Preferably, the bottom end of the upright post is also provided with an anti-falling plate for preventing the leg lifting plate from sliding out of the cylindrical rod of the upright post.

Preferably, the driving motor is a deceleration stepping motor.

The utility model has the following advantages:

after the auxiliary device for lifting the legs on the upstairs is adopted, the lifting device is designed on the crutch, so that perfect compatibility of the lifting device and the crutch is realized, the use of the crutch is not affected when the lifting device is not used, and the practicability of the crutch is improved.

Example 1

Referring to fig. 2-4, an auxiliary device for lifting legs of a upstairs comprises a stand column 1, a leg lifting plate 2, a driving motor 3 and a stay wire 4;

the main body of the upright post 1 is a cylindrical rod 5, and a handle 6 is arranged at the top end of the cylindrical rod 5;

the driving motor 3 is fixedly arranged below the upright post handle 6, a rotating disk 7 is arranged on an output shaft of the driving motor 3, and the rotating disk 7 is fixedly connected with one end of the stay wire 4 and is used for drawing in the stay wire 4 when the driving motor 3 rotates;

referring to fig. 1, the main body of the leg lifting plate 2 is a flat plate, a sliding bearing is arranged on one side of the flat plate, the bearing is matched with a cylindrical rod 5 of the upright post to realize sliding on the cylindrical rod 5, and the upper end of the leg lifting plate 2 is fixedly connected with the other end of the stay wire 4.

In specific implementation, the bottom end of the upright post 1 is also provided with an anti-drop plate 8 for preventing the leg lifting plate 2 from sliding out of the cylindrical rod 5 of the upright post.

In specific implementation, the driving motor 3 is a deceleration stepping motor.

Referring to fig. 2-4, in use, the driving motor 3 is rotated to the longest releasing position of the pull wire 4, the leg lifting plate 2 falls to the lowest position at this time, the user moves the foot onto the leg lifting plate 2 at this time, and the driving motor 3 is started to drive the leg lifting plate 2 to move upwards, so that the leg lifting of the user is realized.
