Abstract

The utility model discloses a blind crutch which comprises a crutch body and a crutch handle, wherein the crutch handle is movably connected with the crutch body; both the crutch body and the crutch handle are made of insulation materials; a cavity (12) is arranged at the upper end of the crutch body (7); a sealed liquid container consisting of the crutch body, an upper conductive plate (10) and a lower conductive plate (8) is arranged in the cavity; mercury (9) is arranged in the liquid container; one end of a lead penetrates through the upper conductive plate in an insulation manner and then is connected with the lower conductive plate while the other end of the lead is connected with the upper conductive plate; and a power supply (4) which is fixed in the cavity as well as a bell (2) and a lamp (3), which are arranged at the upper end of the crutch body, are connected to the lead. Through the utility model, the blind can judge whether obstacles exist in a walking direction, thereby guiding the walking direction for the blind; and when the blind have collision with the obstacles and even fall during the walking, the crutch can send help signals to the surrounding so that the blind can get help from other people when getting body damage during the outdoor walking. The blind crutch is compact in structure, safe and convenient for use, suitable for the outgoing of the blind and the old people.

Description

Blind-man crutch

Technical field

This utility model relates to crutch, especially relates to the crutch that a kind of suitable blind person uses.

Background technology

As everyone knows, generally all will use crutch to judge whether barrier is arranged on the direction of travel when blind person goes out, fall down in case bump with barrier, but for various reasons, blind person's thing of falling down of going out to bump happens occasionally.Fall down in case bump, just might damage blind person's health,,, just might cause serious consequence if can not in time obtain people's relief because the blind person can't use mobile phone outwards to send the relief signal.Though existing crutch goes out to have brought some convenient for the blind person, whether it only is used for judging barrier on its direction of travel, do not have the function that helps the blind person to solve other problem.Therefore, existing crutch role and function ratio are more single, and using has limitation.

The utility model content

The function singleness, the use that exist at blind-man crutch in the above-mentioned prior art have circumscribed problem, this utility model provides a kind of and not only can be the blind person and go out to judge whether barrier is arranged on the direction of travel, and work as the blind person and in case of emergency can help the blind person to send the relief signal, the blind-man crutch that the blind person can in time be succoured.

The technical scheme that the technical problems to be solved in the utility model is taked is: described blind-man crutch comprise turn body and with turn the handle that turns that body is movably connected, describedly turn body and turn handle and make with insulant, the described body upper end of turning has a cavity, in cavity, be provided with by turning body, the sealing fluid container that last conductive plate and lower conducting plate are formed, hydrargyrum is housed in liquid container, and lead one end insulation is connected with lower conducting plate after passing insulator on the conductive plate, the lead other end links to each other with last conductive plate successively with after being arranged on the electric light that turns on the body wall and electric bell and power supply in being fixed on cavity linking to each other again.

For ease of the Push And Release control of dismounting, charging and the power supply of power supply, the pairing body wall that turns of power supply is provided with opening, and opening is provided with the switch lid that links to each other with power supply, when the blind person need go out, the on and off switch on the switch lid is opened; When not using crutch, on and off switch can be closed, when needs charge to power supply, take off the switch lid, attaching plug is inserted socket can charge.

Work process of the present utility model is: the blind person is when walking, and crutch is held in the hand, and crutch is in erectility, at this moment, small amounts of mercury only contacts with lower conducting plate in the liquid container in the crutch cavity, and separates with last conductive plate, circuit is in off-state, and electric bell and electric light are not all worked; When the blind person goes out walking when running into barrier, though do not fall down if bump with barrier, but wishing to obtain other people helps or during relief, the blind person controls oneself and crutch can be fallen, when crutch tilts to certain angle or topples over (becoming horizontal), hydrargyrum contacts with last conductive plate and lower conducting plate simultaneously, circuit is in on-state, and electric bell sends sound, and electric light sends light, by send the tinkle of bells and light signal to periphery, can in time obtain other people help and relief.

This utility model not only can be the blind person and goes out outside to have judged whether barrier on the direction of travel, for blind person's walking points the direction, and when in a single day blind person's walking bumps with barrier even falls down, can send to periphery and help and the relief signal, make the blind person go out to walk in time to obtain other people when health suffers damage and help and relief, this utility model compact conformation, safe and convenient to use is suitable for blind person's out using, also is suitable for old people's out using.
