Description
Background technology
This utility model relates to a kind of blind person's isolated plant, the device that specifically a kind of blind person of guiding walks.
Technical field
Blind or amblyopia personage is the disadvantaged group of current society, and Xian Jin science and technology has been given the normal person superior life now, and those disadvantaged group that just more should be blind or amblyopia personage provide superior, support more next to the shin.
The personage of blind or amblyopia is often when walking, utilize a long pole to click ground, in order to know the place ahead surface state, but the continuous situation on ground, the place ahead often can not completely be grasped, especially the more difficult grasp of the situation of those ground reliefs, make blind or the amblyopia personage difficult to move even one step, and often click ground in walking distance far away, hand can be more tired.
Summary of the invention
This utility model purpose is to provide a kind of guide bar, and it can make the situation on ground, blind person complete grasp the place ahead, and uses easy and conveniently, is convenient to promote and uses.
Technical solution of the present utility model is on the basis of the guide body of rod, this utility model respectively is provided with auxilliary bar particularly in guide body of rod both sides, the end of the guide body of rod and auxilliary bar is provided with guide wheel group, that described guide wheel group is divided into is preceding, in and the rear portion, described front portion is the preceding parallel roller set that links to each other by wheel shaft, described middle part is the transition bracket that links to each other with anterior wheel shaft intermediate bearing, and described rear portion is the back parallel roller set that links to each other with transition bracket; The end of the described guide body of rod and auxilliary bar is fixed on the transition bracket at guide wheel group middle part; Proximal end at the guide body of rod is fixed with a following ultrasound probe, and guide body of rod middle part is fixed with ultrasound probe on another, and the guide body of rod between upper and lower ultrasound probe is provided with ultrasonic depth finder.
More than guide bar described in the utility model each side be provided with two auxilliary bars.
More than described in the utility model before parallel roller set have four parallel rollers to link to each other by wheel shaft.
The roller set of the parallel roller set in back of the present utility model is littler than the diameter of the roller of preceding parallel roller set.
Above-described guide body of rod end is fixed on the bearing of wheel between centers by swivel bearing.
Operation principle of the present utility model is: blind or amblyopia personage guide masthead portion handle, the guide wheel of guide bar end is pressed in road surface, the place ahead, promote the guide bar while going ahead, the guide wheel of guide bar end can reach guide masthead portion handle by the guide body of rod with the situation that contacts on road surface, the place ahead, so just can allow blind or amblyopia personage know the continuous situation on road surface, the place ahead; The both sides of guide bar respectively add auxilliary bar, and auxilliary bar is played a supporting role, and make can not vacillate now to the left, now to the right when the guide bar uses; Special guide wheel group structure, the guide bar can not need manual support just can stand upright on ground, and order is lost one's sight or the amblyopia personage uses lighter, convenient; The end and the middle part of guide bar are provided with ultrasound probe, can survey the obstacle in the place ahead more comprehensively, can tell user the place ahead road surface situation more specifically in advance by the feedback vibrations of ultrasonic depth finder; The preceding parallel roller of guide wheel group is bigger than the parallel roller diameter in back, and the guide bar is face tilt after the meeting then, and user can be more laborsaving when promoting the guide bar; By the parallel roller of suitable increase, can make guide bar balance better, the place ahead surface state can more completely send blind or amblyopia personage to; Between the bearing of guide body of rod end and wheel shaft swivel bearing being set can make turning more steady.
This utility model advantage is: can make the situation on ground, blind person complete grasp the place ahead, and use easy and conveniently, be convenient to promote and use.
