Description
Technical field
The present invention relates to crutch technical field, especially a kind of Special walking stick for blind person.Be particularly suitable for sidewalk for visually impaired people with the use of.
Background technology
The normally used crutch of blind person is made up of crutch handle, crutch bar and crutch leg, and 26S Proteasome Structure and Function is all very single.
Sidewalk for visually impaired people is the designated lane for helping blind person to walk.Sidewalk for visually impaired people is generally divided into two classes, and a class is the sidewalk for visually impaired people of advancing of being laid by the guiding brick of band raised line, and for guiding, blind person is relieved to move ahead; Another kind of is the prompting sidewalk for visually impaired people of being laid by the prompting brick of band round dot, having obstacle, note turning round for pointing out before blind person.Blind person can only be judged guiding the different senses of touch of brick and prompting brick by sole on sidewalk for visually impaired people, can slowly grope to move ahead.Existing crutch cannot with sidewalk for visually impaired people with the use of.
Summary of the invention
The object of this invention is to provide a kind of crutch, by with sidewalk for visually impaired people with the use of, be convenient to blind person quickly and accurately along guiding brick move ahead safely.
Technical scheme of the present invention is: manufacture and design a kind of Special walking stick for blind person, by crutch handle, crutch bar and crutch leg composition, the lower end of described crutch handle is provided with round shrinkage pool, described crutch bar is set to tubular structure, described crutch leg is set to square column structure, the upper end of crutch leg is provided with lower round shrinkage pool, the top and bottom of crutch bar to be inserted respectively in round shrinkage pool and are adopted strong viscose glue gluing fixing in lower round shrinkage pool, main feature of the present invention is: the bottom of described crutch leg is semi-cylindrical, the bottom of crutch leg semi-cylindrical before, the middle part of rear thickness is provided with the arc radius circular groove identical with semi-cylindrical radius, the width dimensions of described circular groove is slightly larger than the width dimensions of the raised line of the guiding brick of sidewalk for visually impaired people of advancing.
The left end of the left wall thickness part of described circular groove is provided with left round shrinkage pool, the right-hand member of described left round shrinkage pool is provided with the left round tube hole communicated, the diameter of described left round tube hole is less than the diameter of left round shrinkage pool, the right-hand member of the right wall thickness part of described circular groove is provided with right round shrinkage pool, the left end of described right round shrinkage pool is provided with the right round tube hole communicated, the diameter of described right round tube hole is identical with the diameter of left round tube hole but be less than the diameter of right round shrinkage pool, left round shrinkage pool, left round tube hole, right round shrinkage pool, the axis of right round tube hole is identical with the axis of circular groove, hexagon socket head cap screw to be inserted in left round shrinkage pool in right round shrinkage pool and to adopt nut to connect locking.
The external diameter end of the hexagon socket head cap screw in described circular groove and the internal diameter close contact of bearing, the sheathed rubber guard ring of external diameter end of described bearing, the external diameter of described rubber guard ring is less than the diameter of circular groove, and the bottom of rubber guard ring is radially less than the height dimension of the raised line of the guiding brick of sidewalk for visually impaired people of advancing to the distance between the bottom of crutch leg.
The material of described crutch handle is rigid plastics, and the material of described crutch bar and crutch leg is aluminium alloy.
Because the width dimensions of circular groove is slightly larger than the width dimensions of the raised line of the guiding brick of sidewalk for visually impaired people of advancing, left wall thickness part and the right wall thickness part of being convenient to circular groove are clamped on the raised line of guiding brick of sidewalk for visually impaired people.
External diameter due to rubber guard ring is less than the diameter of circular groove, the bottom of rubber guard ring is radially less than the height dimension of the raised line of sidewalk for visually impaired people of advancing to the distance between the bottom of crutch leg, when can guarantee that being with the bearing of rubber guard ring to roll on the raised line of the guiding brick of sidewalk for visually impaired people moves ahead, the bottom of crutch leg can not touch the elongated slot bottom land between raised line and raised line.
After the present invention adopts said structure, by with sidewalk for visually impaired people with the use of, be convenient to blind person quickly and accurately along guiding brick move ahead safely.
