Abstract

A device for prompting to take off key after unlocking comprises a battery buzzer with a voice integrated circuit plate arranged in the body case, an inching switch and a key ring. The inching switch is arranged in a block groove and moves through the key ring to block in for cutting the power supply. During taking off the key ring, a circuit is switched on, voice can prompt that the circuit works and reminds a user to take off the key from a lock. The device for prompting to take off key of the utility model is simple in structure and convenient in utilizing, which is an ideal prompting device for avoiding losing keys.

Description

After unblanking, a kind of prompting gets the device of key

The utility model belongs to commodity, is specifically related to the structure that key apparatus is got in a kind of prompting.

Often ignore when people turn the key in the lock and get key, cause key loss, particularly when holding article in the hand, easier key is stayed on the door lock, if taken away by the bad person, then office space or house safety just are difficult to guarantee, get the device of key now after still not having the timely reminds people of a kind of energy to unblank.

The purpose of this utility model is: design the device of getting key after a kind of prompting is unblanked, it can be forgotten when getting key owner, in time reminds, and prevents key loss.

The purpose of this utility model is achieved in that battery, the hummer of speech IC being installed and being attached thereto in a casing, its switch designs is at the key-ring place, circuit disconnection circuit when taking out the key circle of band key is connected when packing the spoon circle into, after time-delay, block of speech work, hummer sends prompt tone, the owner of announcement gets key, have only when key-ring from lock take off snap in spoon ring recess after, cue circuit disconnects, device no longer sends prompt tone.

Fig. 1 is the utility model structural representation

Fig. 2 is the utility model side view

Among the figure: 1 casing, 2 speech IC plates, 3 batteries, 4 buckle, 5 power supply microswitches, 6 spoons of circles, 7 hummers, 8 fixed screws, 9 draw-in grooves.

Introduce the utility model implementation method below in conjunction with accompanying drawing:

Sound circuit plate 2, battery 3, hummer 7 are installed in casing 1, and power supply microswitch 5 is positioned at the draw-in groove 9 on the casing 1, and spoon circle 6 is stuck in the draw-in groove 9, connects on casing 1 bonnet to buckle 4.

Buckling of this device 4 hung on the waistband, key is inserted on the spoon circle 6, in the spoon circle card entry slot 9, when needs are opened, key circle 6 is taken out in draw-in groove 9, at this moment power supply microswitch 5 is connected, and circuit working is after the time-delay several seconds, hummer 7 makes and can send the prompt tone of getting key, after key was snapped in draw-in groove 9 together with spoon circle 6, microswitch 5 was disconnected by the promotion of spoon circle 6, and the circuit hummer 7 that quits work is no longer sounded.

The utility model is simple in structure, and is easy to use, is the suggestion device that prevents that key loss is desirable.

Claims (2)

1, get the device of key after a kind of prompting is unblanked, it buckles (4) power supply microswitch (5) spoon circle (6) hummer (7) by casing (1) speech IC plate (2) battery (3) forms, and it is characterized in that: microswitch (5) is positioned at draw-in groove (9).
