Description

Simple and easy automatic flasher

The utility model relates to a kind of flasher, particularly a kind of school bag that can be applicable to, the simple and easy automatic flasher of knapsack etc.

Along with expanding economy, motor vehicles are increasing, cause traffic hazard constantly to increase, and especially for students in middle and primary schools, owing to the age, cause students in middle and primary schools that traffic hazard takes place especially easily.Once released a kind of safe school bag on the market, flasher is installed on school bag, glittering by switch control flasher reaches and causes that the driver notes reducing the effect of traffic hazard.

But above this school bag flasher exists a significant disadvantages, if be exactly that child forgets when opening switch, just flasher is not glittering, forgets and turn off that the power consumption of constantly glistening again causes the very big inconvenience in the use if opened.

The purpose of this utility model is to avoid the shortcoming that exists in the above-mentioned prior art and a kind of simple and easy automatic flasher that can be used for school bag, knapsack etc. is provided, it can be at endorsement bag (knapsack) when walking about, signal automatically can flash, when putting down school bag (knapsack), can close the flashing signal of going out automatically again.

The purpose of this utility model can reach by following measure;

The utility model is made of housing, power supply, luminophor, it is characterized in that; On housing, a sheet metal and a tinsel with holes fixedly is housed, tinsel passes the hole on the sheet metal.

Fig. 1 is a structural drawing of the present utility model.

Fig. 2 is a circuit diagram of the present utility model.

The utility model will be further described below in conjunction with accompanying drawing:

1 is housing, and 2 is sheet metal, and 3 is the hole, and 4 is tinsel, and 5 is power supply, and 6 is luminophor.

The utility model is made of housing 1, sheet metal 2, hole 3, tinsel 4, power supply 5, luminophor 6, sheet metal 2 and tinsel 4 all fixedly are loaded on the housing 1, on sheet metal 2, have hole 3, tinsel 4 passes the hole 3 on the sheet metal 2, tinsel 4 has certain rigid, can vibrate, sheet metal 2 links to each other with the both positive and negative polarity of power supply 5 respectively with tinsel 4, and forms current return with luminophor 6.

The utility model is when practical application, place it in the back side of school bag (knapsack), when child shoulders school bag and walks, because the swing when walking, tinsel 4 on the flasher is swung, and tinsel 4 can constantly contact with sheet metal 2 in swing process, tinsel 4 and sheet metal 2 every contacts once, make the formation current return, make luminophor 6 luminous, after the disconnection, luminophor 6 makes not luminous, because the swing of tinsel 4 just constantly contacts with sheet metal 2 or disconnects, and make luminophor 6 send flickering light, thereby it is glittering to reach flasher, cause other people, the generation of traffic hazard is avoided or is reduced in the effect that the driver notes.

When school bag does not use, after putting down,, make the not luminous swing of tinsel 4 and static because school bag is not swung staticly, tinsel 4 does not just contact with sheet metal 2, makes luminophor 6 not luminous, and flasher stops automatically, thereby reaches the effect of power saving.

The utlity model has simple in structurely, easy to manufacture, easy to use, safe and practical is excellent The point.

Claims (2)
