Reason easily causes the unstable of walking, or even falls.And after injury of falling, and will further result in the decline of its walking-function.
If tumble is hurted sb.'s feelings and cannot be trained in time, it will enter by being unable to leave the bed the vicious circle until dead.Hospitals at Present
In physiotherapy scholar it is opposite lack, status is acute stage after hospital receives one section of training, would have to go home voluntarily to train,
Until fully recovering.Therefore, the daily walking as the auxiliary bad old man of legs and feet perhaps lower limb disability people is used or as recuperating
When walking function resume training use, have recently emerged various walking assisting device products.
But walking assisting device is stayed at home, interior is in use, may encounter the barriers such as indoor threshold, by being laid on ground
Crowning caused by carpet side on plate etc. is likely to be encountered the barriers such as handstone in outdoor application, raised not plane
Road.Since the car body of walking assisting device is light, even small barrier, or slight raised not plane, all easily cause step
Row assistor stops suddenly, and the user to walk is made to collide with walking assisting device, causes user frightened.Seriously
When, due to barrier or raised not plane, it may cause walking assisting device and overturn, cause itself of user
Damage.Therefore, in order to avoid stopping or reverse accident suddenly occurs in walking assisting device, it is desirable that walking assisting device must have one
Fixed more hinders ability.However, at present, there are no the walking assisting device products with barrier getting over mechanism in the world.
Utility model content
The purpose of this utility model is to provide a kind of preceding four-wheel walking assisting device barrier getting over mechanism, solve in background technique
The problem of proposed.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: preceding four-wheel walking assisting device obstacle detouring machine
Structure, more barrier component, castor including two vertical leg pipes and two lever mechanisms, the more barrier component of the lever mechanism include

The connection of walking assisting device bracket.
Preferably, the rotating shaft of the more barrier component of two lever mechanisms, is to connect with two vertical leg pipe fronts, or be located at
Below two vertical leg pipes, it is connect by connecting bracket with vertical leg pipe.
Preferably, it is equipped at least one castor on vertical leg pipe, or is equipped in the lower section of vertical leg pipe by connecting bracket
At least one castor.
Preferably, it can be equipped with horizontal foot tube between two vertical leg pipes, be also possible to gap.
Preferably, two vertical leg pipe rear portions can be equipped with more barrier component.
Preferably, one-way wheel can be used in the component castor and castor, and universal wheel also can be used, and also can be used complete
To wheel.
The technical solution of the utility model has the following characteristics that the vertical leg pipe front of 1 ﹑ walking assisting device, is not directly to pacify
Castor is filled, but is respectively equipped with the more barrier component as lever mechanism, the both ends of more barrier component wheel bar have set component castor, institute
When encountering barrier with the component castor of the walking assisting device with the utility model barrier getting over mechanism, component castor and barrier
Contact force rotates the rotating shaft in more barrier component, stops suddenly so as to avoid walking assisting device or reverse, simultaneously
Walking assisting device can also be made to clear the jumps.2 ﹑ are using the walking assisting device for installing the utility model barrier getting over mechanism, due to tool
Have it is good more hinder ability, so either using as auxiliary walking, or use is resumed training as walking function, when front is touched
It is not easy to stop suddenly when to obstacle or reverse, so as to improve walking assisting device safety.3 ﹑ mechanisms are simple, are easy to real
It is existing, it is at low cost.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As depicted in figs. 1 and 2, preceding four wheeled walking assisting device barrier getting over mechanism, including two vertical leg pipes 4 and two Lever machines
The more barrier component 1, castor 7 of structure.The more barrier component of lever mechanism, includes wheel bar 9 and rotating shaft 8, wherein rotating shaft 8 is located at wheel
The center of bar 9, wheel 9 both ends of bar are equipped with component castor 6, the rotating shaft 8 of the more barrier component 1 of two lever mechanisms, be with
Two 4 front of vertical leg pipe connections, or it is located at two vertical leg pipes, 4 lower section, it is connect by connecting bracket with vertical leg pipe 4, in vertical leg
Pipe 4 be equipped at least one castor 7, or the lower section of vertical leg pipe 4 by connecting bracket be equipped at least one castor 7, two
