Abstract

A floor pushing type photoelectric blind crutch makes used of photoelectric technology and principle of machinery to perform omnibearing detecting travelling region. Photoelectric probe heads (key component of the overground alarm system) are arranged on a cross bearer. The detection region of the photoelectric probe heads is an infrared photo vertical plane with height of 1.7m and width of 0.4m in front of users. Photoelectric probe heads gives response if there is object entering into the plane and start alarm mechanism to alarm. Ground detection system of the detection mechanism is constituted by ground wheel, towing wheel, towing handle and shaft. Ground wheel contacts with the ground. Blindman can directly feel the condition of the rough ground through the handle. There is a towing wheel between the ground wheels. the towing wheel will fall into a pool between the ground wheels under self gravity, which drives the moving contact on the upper end of the towing handle to contact the stationary contact on the cross bearer to form a closing circuit, thereby initiating alarm. The invention has the advantages of accurate, timely, and reliable alarm, convenient operation, and good labour saving.

Description

Floor type photoelectric blind stick

Technical field

The present invention relates to a kind of blind battle, especially a kind of driving photoelectric blind stick that lands.

Background technology

At present, known blind battle kind is a lot, but all exist some shortcomings, as keep away unavoidably bump from unsettled object, resemble lower doorframe, hang clothesline, the branch of expenditure etc., the blind person who also has can not crash into down in the well because of the cane point fully contacts accidentally with ground, solves such problem so a kind of product of their exigence is helped them.

Summary of the invention

For solve the blind person go on a journey inconvenience, improve the problem of existing blind battle, the invention provides a kind of floor type photoelectric blind stick, the not only comprehensive detection of this blind battle district of advancing, and accurately and timely, easy to operate, to remedy the deficiency of existing product.

The technical solution adopted for the present invention to solve the technical problems is: adopt detection agency, hand-held controlling organization and alarm mechanism, detection agency divides to be surveyed and ground location two systems on the ground, the core component of warning system has the photoelectricity gauge head on the ground, buzzer and gauge tap are formed, the photoelectricity gauge head is installed on the crossbearer, gauge head up, range finding is adjustable in 2 meters scopes, height according to the blind person is decided, the photoelectricity gauge head totally two be divided in the crossbearer two ends, at a distance of about 0.4 meter of the width that is the people, the search coverage of two photoelectricity gauge heads is the high about 1.7 meters wide about 0.4 meter infrared ray vertical planes in blind person the place ahead, this plane moves ahead synchronously with the blind person, when object enters the plane, the photoelectric probe reaction, the effect alarm mechanism is reported to the police; The ground location system of detection agency is by landing wheel, tugboat, drawbar and axle constitute, the bye of landing is enclosed within on the axle, axle is fixed on the crossbearer, crossbearer is connected with lower end battle bar, battle bar in lower end is fixedlyed connected by telescopic joint with upper end battle bar, and upper end battle bar connects handle, and the wheel that lands contacts with ground, the blind person directly experiences the uneven situation on ground by handle, two land the wheel in the middle of a tugboat is arranged, tugboat is placed on the drawbar, the drawbar sky is enclosed within on the axle, stretch out the drawbar upper end, there is a movable contact its end, a stationary contact on the corresponding crossbearer, and tugboat contacts with ground, when advancing, run into two and land when wheel is middle dell, tugboat drives drawbar and turns clockwise in the hole that hangs under the effect of gravity, stationary contact on the drawbar upper end movable contact contact crossbearer causes warning thereby form closing of circuit; Hand-held controlling organization is made up of handle, main switch, power supply (set of cells), care sound switch and warning lamp switch; Alarm mechanism is formed by looking after sound buzzer, photoelectricity buzzer, tugboat buzzer and warning lamp.

The invention has the beneficial effects as follows that for the blind person provides a kind of blind battle of brand new technical, utilize the comprehensive detection of photoelectric technology and the theory of mechanics district of advancing, it is accurately and timely reliable, easy to operate, laborsaving to report to the police.

The specific embodiment

In Fig. 1 and Fig. 2: handle is equipped with battery as power supply in (2), main switch (1) is installed on the handle (2), look after sound switch (3) and warning lamp switch (4), handle (2) is connected with upper end battle bar (9), on the upper end battle bar (9) warning lamp (5) is housed, look after sound buzzer (6), photoelectricity buzzer (7) and tugboat buzzer (8), lower end battle bar (11) is fixedlyed connected by telescopic joint (10) with upper end battle bar (9), lower end battle bar (11) is connected with crossbearer (12), crossbearer (12) is a tubular, in be equipped with the axle (15), the empty cover in axle (15) two ends lands wheel (14), the wheel (14) that lands contacts with ground, two land and have a tugboat (16) also to contact with ground in the middle of the wheel (14), tugboat (16) lands idle running on drawbar (17), drawbar (17) sky is enclosed within on the axle (15), stretch out drawbar (17) upper end, there is a movable contact (18) its end, corresponding crossbearer (12) last stationary contacts (19), crossbearer (12) respectively is equipped with a photoelectricity gauge head above the two ends, gauge head up, range finding is adjustable in 2 meters scopes, height according to the blind person is decided, and the search coverage of two photoelectricity gauge heads is the high about 1.7 meters wide about 0.4 meter infrared ray vertical planes in blind person the place ahead; Detection agency divides to be surveyed and ground location two systems on the ground, the core component of warning system has two photoelectricity gauge heads and photoelectricity buzzer (7) on the ground, the ground location system is by landing wheel (14), tugboat (16), drawbar (17), movable contact (18) and stationary contact (19) formation, and the blind person directly experiences the situation of ground relief by handle (2).
