Abstract

This utility model relates to a kind of blind-man crutch, it comprises cane body, angle demodulator, mercoid switch, also comprise hands handle, vibrator, universal wheel, main switch, when using this utility model, hand-held hands handle when blind person goes out, universal wheel is placed on the ground, can all-direction rotation, main switch is opened during use, angle demodulator is adjusted to certain setting value, angle demodulator is by rotating shaft pilot angle, thus the standard value range that control mercoid switch (24) detects, once there is descending, the concavo-convex surface conditions that waits is, mercoid switch is connected, circuit communication, vibrator vibrates, reminding blind notes surface conditions.

Description

Blind-man crutch
Technical field
This utility model relates to a kind of blind-man crutch, especially a kind ofly can carry out according to road gradient situation the blind-man crutch reminded.
Background technology
Blind person is in daily life and trip, mostly need crutch as aid, existing common blind-man crutch lacks the warning function for surface conditions, the situation that when easily causing descending or road surface to change, blind person falls down, and blind person is always with crutch point ground, very difficultly, the existing technology such as crutch many employings infrared ray, GPS with prompting function on the market, cost is higher, design is complicated, expensive, easily can cause the situation that blind person can't afford.
Utility model content
For the deficiency of above-mentioned blind-man crutch, the purpose of this utility model is to provide a kind of cheapness, convenience and have the blind-man crutch of road surface prompting function, it adopts the Power Supply fittings such as mercoid switch, vibrator, not only reduces cost but also can play suggesting effect, efficiently solves the problems referred to above.
The technical scheme adopted to realize the purpose of this utility model is: a kind of blind-man crutch, it comprises cane body, angle demodulator, mercoid switch, it is characterized in that: also comprise handle, vibrator, universal wheel, main switch, vibrator is located on handle, angle demodulator and mercoid switch are located at it cane, mercoid switch connects vibrator and angle demodulator, and angle demodulator controls the standard value range that mercoid switch detects; Cane is also provided with switch, battery with it, and battery adopts rechargeable battery or disposable aneroid battery; Universal wheel is located at cane body afterbody; Angle demodulator and mercoid switch are by rotating shaft and wired in series, and angle demodulator changes wire angle by rotating shaft, control the standard value range that mercoid switch detects; Main switch and vibrator, angle demodulator, mercoid switch, serial battery, main switch controls whole circuit opening and closing.Handle adopts anti-slip material to make.
The beneficial effects of the utility model are: can point out surface conditions again by rolling on the ground for crutch, and structure is simple, easy to operate, cost is lower, practical, carry with very easy to use.Be applicable to most of blind person.

Detailed description of the invention
Illustrate that the utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
A kind of blind-man crutch, comprise cane body (2), angle demodulator (22), mercoid switch (24), it is characterized in that: also comprise handle (1), vibrator (11), universal wheel (3), main switch (21), angle demodulator (22), mercoid switch (24), vibrator (11) is located on handle (1), angle demodulator (22) and mercoid switch (24) are located on cane body (2), mercoid switch connects vibrator (11) and angle demodulator (22), angle demodulator (22) controls the standard value range that mercoid switch (24) detects, cane body (2) is also provided with switch (21), battery (23), battery (23) adopts rechargeable battery or disposable aneroid battery, universal wheel (3) is located at cane body (2) afterbody, main switch (21) is connected with vibrator (11), angle demodulator (22), mercoid switch (24), battery (23), and main switch (21) controls whole circuit opening and closing, handle (1) adopts anti-slip material to make, main switch (21) is connected with vibrator (11), angle demodulator (22), mercoid switch (24), battery (23), and main switch (21) controls whole circuit opening and closing.
Angle demodulator (22) comprises rotating shaft (221) and wire (222), mercoid switch (24) and angle demodulator (22) are by rotating shaft (221) and wire (222) series connection, during use, angle demodulator (22) changes the angle of wire (222) by rotating shaft (221), thus control the angle of mercoid switch inside conductor, the angle of inclination that crutch is different can be detected.
In the embodiment shown in Fig. 1, Fig. 2, when using this utility model, hand-held handle when blind person goes out, universal wheel is placed on the ground, can all-direction rotation, opens main switch during use, angle demodulator is adjusted to certain setting value, angle demodulator by rotating shaft pilot angle, thus controls the standard value range that mercoid switch (24) detects, once there is descending, the surface conditions such as concavo-convex is, mercoid switch is connected, circuit communication, vibrator vibrates, and reminding blind notes surface conditions.
These are only embodiments more of the present utility model, to those skilled in the art, under the prerequisite not departing from this utility model creation design, also can carry out some distortion and improvement, these all belong to this utility model protection domain.
