Abstract

The utility model relates to a sound-light alarm for angling, belonging to the fishing device. The sound-light alarm for angling has the advantages of simple structure, light weight, high reliability, few elements, small electric current, 1.5 volt battery, a printed circuit board, and high sensitivity. When the fish eats the bait or be caught, the sound-light alarm gives an interrupting alarm. The alarm is more obvious when the fish is caught.

Description

The fishing audible-visual annunciator

The fishing audible-visual annunciator is to belong to device for use in fishing trawl.

The fishing audible-visual annunciator of Japan, Taiwan, the U.S. is seen in market, 11 kinds of components and parts is housed, complex structure in bigger 66 * 30 * 30mm body of small product size.

The utility model purpose provides a kind of improved fishing audible-visual annunciator, and the shortcoming sensitivity that has overcome existing alarm is low, can be interrupted warning, good reliability.

This fishing audible-visual annunciator, volume is 56 * 26 * 30mm, and printed circuit board (PCB) is arranged, and is made up of 7 kinds of components and parts.1, the transformer of Cai Yonging can cooperate the electric capacity vibration, and energy up voltage 18～21V makes magnetic core with manganese-zinc-ferrite, and exoskeletal, magnetic resistance is little.2, piezoelectric patches energy sounding uses as electric capacity, cooperates vibration with inductance.3, triode can vibrate and amplify, and the double as commutation diode is used again.4, resistance optimum value 15～20K can provide the triode bias current.5, light emitting diode is in parallel with resistance provides a pressure drop, burning voltage effect.6, adopt  3 * 20 tongue tubes and  8 * 3.5 permanent magnets to form contactless closed magnetic switch.7, little button driving member is formed little shaft transmission system radial motion by cold rolling M3 * 14 brass screws and M 3 * 5 standard component compressing tablet copper nuts, is different from the axial transmission of fishing audible-visual annunciator of the U.S..

Advantage of the present utility model: electric current is little, in light weight, circuit structure is simple, element is few, Low, the expense 60～80% that reduces cost of cost, the economic benefit height is with No. 8 batteries of a joint 1.5V, have the battery can be with 6 months, efficient height, highly sensitive, the acute angle top of its screw The center of spring, spring is combined with the magnetic patch mold insert, and rise and adjust degree of tightness (sensitivity) and reset response, Little axle is fixed together with the little button of clamping fish string, and the inner end of axle and magnetic patch mold insert are riveted together Fish such as 20 grammes per square metres eats food or rises to the bait, the fish string drives little button and magnetic patch is done radially back and forth to move synchronously Moving 1～3 millimeter, namely send acousto-optic newspaper pipe with the effect of tongue tube generation magnetic control, be exactly at 10 meters Chimes of doom also can be heard in place in addition, and use best night, also can make doorbell or bicycle bell, water In angle the little button of string and alarm clamping fish string to close in succession, fish eats several secondary eclipses and reports to the police several times, is interrupted newspaper Alert, a fish snapped at the bait, and alarm is more obvious. And the acousto-optical alarm for fishing of the U.S., as long as fish bumps one Lower, and the alarm sound is continuous, must press cut-off switch can stop.

The utility model result of use is good, makes easily, and during warning 10～20 milliamperes, new electricity Battery 1.8V is along with using voltage drop 0.9V, and alarm is just as usual work still.
