Description

Technical Field

[0001] The utility model belongs to the technical field of walking assistance, and particularly relates to a walking assistance device for the elderly. Background Art

[0002] According to the patent document with the authorization announcement number of "CN214435293U" and the invention name of "A Walking Assistance Device for the Elderly", it is recorded in the specification that through the mutual cooperation of a U-shaped rod, a first screw rod, a movable pipe, a sleeve, a fixed rod, a connecting rod, a grip and a universal wheel, most of the body weight can be transmitted to the fixed rod through the armpits, reducing the weight borne by the elderly's arms and palms during walking. This walking assistance device is more suitable for the elderly with relatively poor grip and arm strength, and can also reduce the fatigue of the arms of general elderly people when walking. The elderly can use more time for upper limb rest for walking exercise, thus improving the walking exercise effect of the elderly. In addition, the device can be adjusted according to the length of the elderly's arms, making it more flexible to use; through the mutual cooperation of a fixing mechanism, a support rod, a round pipe, a support seat and a third screw rod, the walking assistance device can be adjusted to a fixed state after use, improving the stability of the walking assistance device. When the elderly use it next time, they can better rely on the walking assistance device to get up, and there will be no problem that the elderly support improperly and fall due to the easy sliding of the rollers at the bottom of the walking assistance device. Moreover, the adjustment is convenient without bending down, and the elderly can operate it alone, thus improving the flexibility and safety of the walking assistance device; through the mutual cooperation of an adjustment mechanism, a second screw rod, a bidirectional internal thread pipe, a lifting rod, a slider, a seat board and a sliding groove, the distance between the two fixed rods can be adjusted according to the distance between the two armpits of the elderly, so as to be suitable for the elderly with different shoulder widths, and at the same time, the comfort of the device during use is improved, providing convenience for the elderly to use. However, there are still the following defects:

[0003] When the elderly need to rest during long-term walking, the fixation of the device needs to be carried out through the mutual cooperation of a fixing mechanism, a support rod, a round pipe, a support seat and a third screw rod, which is rather troublesome and inconvenient for the elderly to use. Summary of the Utility Model

[0006] The side protection component includes a base. Moving wheels are installed at the four corners of the bottom end of the base. Longitudinal rods are symmetrically installed at the top end of the base. Side protection rods are fixedly installed at the top ends of the longitudinal rods. Both ends of the connecting protection rod are fixedly connected to the two longitudinal rods at the same position on the two bases respectively. A support and auxiliary component is installed on the side protection rod, and a stop and stability component is installed on the base.

[0007] Preferably, the support and auxiliary component includes two fixing rings symmetrically installed at the bottom end of the side protection rod. A screw rod is provided inside the fixing ring. Support longitudinal rods are installed at the mutually approaching ends of the screw rods below the two side protection rods. A support cross rod is fixedly installed at the top ends of the two support longitudinal rods on the same side. A rubber pad is arranged outside the support cross rod.

[0008] Preferably, two limit nuts are threadedly installed on the outer side of the screw rod. The two limit nuts are respectively in close contact with both sides of the fixing ring. Two of the support cross rods are located on the mutually approaching side of the two side protection rods.

[0009] Preferably, the stop and stability component includes through grooves symmetrically formed in the base. Both ends of the through groove penetrate to the upper and lower sides of the base respectively. A connecting frame is provided above the base. Friction rods are symmetrically installed at the bottom end of the connecting frame. The friction rods are movably installed inside the through groove. Springs are symmetrically installed at the bottom end of the connecting frame. The bottom ends of the springs are fixedly connected to the base.

[0010] Preferably, a sliding sleeve is sleeved on the outer side of the support longitudinal rod. A grip rod is arranged between the two sliding sleeves. Connecting rods are symmetrically installed at both ends of the grip rod. The connecting rods are fixedly connected to the sliding sleeve.

[0011] Preferably, a vertical plate is fixedly installed at the bottom end of the connecting rod. A transverse rod is fixedly installed at the bottom end of the side of the vertical plate close to the connecting frame. The transverse rod is movably installed inside a horizontally arranged rod groove. The horizontally arranged rod grooves are symmetrically formed inside the connecting frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] During work, the connecting protection rod and the two side protection rods can protect the front and both sides of the elderly. The support cross rod can support under the armpits of the elderly. Moving wheels are installed at the bottom end of the base, which is convenient for the elderly to move. At the same time, the screw rod can be horizontally adjusted inside the fixing ring, so that the distance between the two support cross rods can be adjusted, which is convenient for the elderly with different body shapes to use;

[0014] During work, the friction rod set is not in contact with the ground under the elastic force of the spring. When rest is needed, the elderly push the grip rod downward with both hands, and then push the friction rod downward until the bottom end of the friction rod is in close contact with the ground. Under the action of the friction force, the support stability during rest is improved. Description of the Drawings
