Description

A kind of power-assisted Oxter crutch

Technical field

The present invention relates to rehabilitation medical ancillary equipments, more particularly to a kind of power-assisted Oxter crutch.

Background technology

Underarm crutch is medical crutch, be many lower limb disability persons must with object, general Oxter crutch body upper part is to turn Cane armpit support, middle part are the handles consistent with the direction of armpit support, need powerful arm strength to support when using oxter cane, and Crutch is without elasticity, very easy fatigue bigger to the impact force of user oxter；In order to mitigate the muscle power of crutch user Consumption, present occur that setting compressed spring damping stores power on a kind of crutch foot in the market, springs back booster type Oxter crutch, this Although kind crutch solves shock problem of the crutch to oxter, for the solution useless of the consumption problem of arm strength, due to elasticity part The lower part of crutch always allows user to feel underfooting shakiness, but also there are complicated, it is not easy to the shortcomings that fabricating； Patent（CN 204812452 U）A kind of damping telescopic crutch is disclosed, its elasticity part is arranged on the top of crutch, still Spring is exposed can not to be constrained outside, do not have stable effect.

Invention content

In order to solve the deficiencies in the prior art, the object of the present invention is to provide a kind of simple in structure, it is easily worked Manufacture uses a kind of steady, the strong energy accumulated assisted Oxter crutch of arm strength power-assisted.

The technical scheme is that a kind of such, energy accumulated assisted Oxter crutch, including crutch body and crutch armpit support, The crutch body lower part is fixedly connected with crutch foot, and there are handle, the long open-work that top both sides have position opposite, armpit support in middle part Centre position be fixedly connected with downward rebound casing, springing back the position that both sides are opposite at ferrule openings has round open-work, springs back There are spring, rebound casing to be sleeved on crutch body upper end in casing, connecting shaft passes through circle open-work and long open-work, and the position of spring is limited Between the crutch body and armpit support that are scheduled in rebound casing.

Furtherly, the connecting shaft both ends are fixedly connected with circle open-work.

Furtherly, the connecting shaft is to be flexibly connected with long open-work.

Furtherly, the internal diameter of the rebound casing is more than the outer diameter of crutch body.

Furtherly, the crutch body is fixedly connected with handle.

Furtherly, the length of the connecting shaft is equal with the rebound diameter of casing.

Furtherly, there is anti-skid structure below the crutch foot.

Furtherly, the crutch foot is square.

Furtherly, the crutch foot is rounded.

Advantageous effect

A kind of energy accumulated assisted Oxter crutch of the present invention stores power using pressure stretch damping, and pull-up rebound power-assisted is simple in structure, is easily worked Manufacture, power assistant spring are arranged in the top of handle, can effectively mitigate the consumption of arm strength, play the role of good power-assisted, prevent The anti-skid structure of sliding surface increases the frictional force of non slip surface, the crutch body and armpit support of the position restriction of spring in springing back casing Between, stability is strong；Good antiskid effect of the present invention, saves labor, easy to use.

Specific implementation mode

One embodiment of the present of invention is introduced below in conjunction with the accompanying drawings.

As shown in Fig. 1 and 2, a kind of technical solution of power-assisted Oxter crutch of the present invention is a kind of such, power-assisted underarm crutch Cane, crutch armpit support（5）Centre position be fixedly connected with downward rebound casing（6）, spring back casing（6）Opening both sides are opposite Position have round open-work（8）, crutch body（1）Lower part and there is anti-skid structure（3）Crutch foot（2）It is fixedly connected, crutch body （1）There is handle (4) at middle part, springs back casing（6）Internal diameter be more than crutch body（1）Outer diameter, there is spring in centre（7）Rebound set Pipe（6）It is sleeved on crutch body（1）There are length and rebound casing in upper end（6）The equal connecting shaft of diameter（10）Across circle open-work （8）With long open-work（9）, by spring（7）Position restriction rebound casing（6）In crutch body（1）With armpit support（5）Between, Connecting shaft（10）Both ends and circle open-work（8）It is fixedly connected, with long open-work（9）It is flexible connection.

Hand-held handle when use（4）, by armpit support（5）It is placed in oxter, crutch foot（2）Lower part and anti-skid structure（3）It places On the ground, so that it may which, with walking, the support leg of user leaves ground, armpit support（5）Stress springs back casing（6）It moves downward, Gu It is scheduled on rebound casing（6）On connecting shaft（10）Elongate spring（7）, connecting shaft（10）In long open-work（9）In run down and store Can, the foot that user moves forward supports ground, the spring of accumulation of energy（7）It pulls back power-assisted, connecting shaft（10）Uplink resets simultaneously It releases energy, crutch foot（2）Forward support, user can walk on.

What has been described above is only a preferred embodiment of the present invention, it is noted that the ordinary skill people of this field is said, Without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the guarantor of the present invention Within the scope of shield.
