Description

Helping hand walking stick of squatting

Technical Field

The utility model relates to a walking stick especially relates to a helping hand walking stick of squatting.

Background

The crutches are common walking aids, and the common crutches on the market can be divided into two types, namely armpit crutches mainly aiming at body support and rehabilitation treatment after leg injuries, and the daily walking aids mainly aiming at the elderly.

For example, the chinese utility model with the publication number CN 2115100U discloses a movable underarm crutch, which comprises a leg tube, a supporting tube, a handle and a back cushion, and has a stable structure and reliable mechanical properties. The armpit is used as a supporting point, and the user can easily support the whole body, so that the stress of the legs is reduced, and the injured leg is assisted for the user to walk. In addition, chinese utility model patent with publication number CN 206063387U discloses a walking assistance system, wherein the walking stick comprises a head, upper and lower guide rods, and four sets of support rods and fixing rods annularly and uniformly distributed around the lower guide rod. A stable supporting part is constructed by four groups of supporting rods and fixing rods, the contact effect between the stable supporting part and the ground is good, and the situation that a user falls down and the like due to unstable supporting is not easy to happen. Is suitable for the old with inconvenient legs and feet to walk in a daily assisting way.

For users with inconvenient legs and feet, the actions of squatting and rising are also greatly limited except for the rehabilitation process and the daily walking. By analyzing the stress conditions of all parts of the human body in the process of rising and squatting, when the human body rises and squats, the knees and the shanks are used as fulcrums, the moment of the hip joint is used as main driving force, and the thighs and the upper limbs of the human body are lifted. In the process, the knee, the hip joint and the leg muscle receive great pressure, so that the hip joint strength of people with inconvenient legs and feet, particularly the old, is seriously declined, the bone bearing capacity is also reduced, the squatting action is difficult to independently complete, tools are needed for assistance, and the conventional crutch in the market does not have the squatting assistance function.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a helping hand walking stick of squatting rises and squats on helping hand walking stick's basis, increases the helping hand function of squatting.

In order to solve the technical problem, the utility model provides a technical scheme as follows: the squatting assistance crutch comprises a main rod, wherein one end of the main rod is provided with a supporting part, the supporting part is provided with two symmetrically arranged supporting rods, and a foot accommodating area is formed between the two supporting rods; the mobile jib on still be equipped with handheld portion, handheld portion be located the mobile jib and keep away from the one end of supporting part, or be located mobile jib one side and keep away from the supporting part setting.

When a user squats, the user inserts feet into the foot containing area, grasps the hand-held part, and takes the pulling force of arms as the auxiliary power for squat, thereby reducing the burden of knee, hip joint and leg muscles. The acting force of the ground to the supporting rod is used as the main supporting force of the crutch, and the foot part plays a role in preventing the supporting part from sliding along the contact point of the ground, so that the safety of the user in the squatting process is ensured. Meanwhile, the squatting and rising power-assisted crutch can also be used as a common walking-assisted crutch, and has comprehensive functions.

Compared with the walking assisting system with the publication number of CN 206063387U in the prior art, the walking assisting system has the advantage that the contact stability between the supporting part and the ground is poor when the walking assisting system is in a walking assisting state. However, when the crutch is in the squatting assistance state, the arrangement of the supporting rod and the foot accommodating area can ensure that the crutch can freely tilt and swing in the front and rear directions while being matched with the foot of a user, so that the assistance in different directions required by the user in the squatting assistance process is realized.

Preferably, the length of the main rod is adjustable so as to adapt to users with different heights.

Preferably, the bottom of the supporting rod is provided with a non-slip mat. The use state of the crutch is analyzed, and the crutch needs to incline outwards relative to the human body in the process of rising in the squatting position, so that the crutch has the possibility of sliding towards the rear side direction of the human body. Although the crutches cannot slide over a large range with the user's foot inserted into the foot-receiving area, the relative motion of the crutches can cause greater stress on the user's angle, especially under impact loads, which can easily cause injury to the user's foot. And the setting of slipmat has improved the coefficient of friction between bracing piece and the ground, has reduced the possibility that the walking stick skids in the use, has improved the safety in utilization.

Preferably, the main rod is provided with a knee protection pad, and the distance between the knee protection pad and the supporting part is adjustable. During normal squatting, the knee is an important rotation supporting point and an important stress point, and after the power-assisted crutch is added, the knee is still one of the important supporting point and the important stress point. Set up knee pad on the mobile jib, the in-process of squatting, the knee can pass through knee pad and mobile jib contact, and human shank leans on each other with the walking stick for walking stick and human support are all more stable, and knee pad can reduce the injury of walking stick to the knee in the at utmost simultaneously. The distance between the knee protecting cushion and the supporting part can be adjusted to adapt to users with different heights.

Preferably, the knee pad is rotatably and movably connected with the main rod, and the rotation center of the knee pad is perpendicular to the main rod. The person is at the in-process from squatting position to standing position, and the inclination of shank can take place certain change, behind the helping hand walking stick with the help of this application, and the relative angle between shank and the walking stick also changes, and knee bolster rotation sets up, can ensure to stand the in-process all the time and perfectly laminate with the shank knee, plays the effect of protection knee to the at utmost.

Preferably, the foot protection device further comprises a foot protection plate which is arranged in the foot accommodating area and is connected with the supporting part in a back-and-forth swinging mode. At the in-process of squatting, the user foot plays the effect that prevents the supporting part and slide to human back, and at this in-process, the supporting part can the foot have great pressure, and the setting up of banket board can reduce the pressure of supporting part to the foot, and then reduces the possibility that causes the injury to the human body. The foot protection plate is arranged in a swinging way relative to the supporting part, so that the fit degree of the foot protection plate and the instep can be improved.
