Abstract
The utility model comprises a circuit board which is provided with a touch switch, an acceleration switch, a trigger, a logic circuit, a delay circuit and an electric sound generator, and a power supply. The touch switch and the acceleration switch are connected in series to be connected with the input of the trigger. The output of the trigger is connected with the delay circuit and the electric sound generator through the logic circuit. The output of the delay circuit is connected with the reset input of the trigger. When two conditions for disposal and movement are satisfied, the utility model can emit an alarm sound. Therefore, a throw apparatus can emit a sound in flight, which alarms spectators or pedestrians. The throw apparatus can not emit a sound accidentally, which can prevent false appearance or condition for disturbing people from appearing.
Description
The utility model relates to the alarming device that is used to throw equipment.
When carrying out the throwing training that discus, grenade, javelin etc. throw equipment, owing to place restriction, personnel's carelessness or the like reason, occur injuring the pedestrian by a crashing object easily, accident situation such as the place that flies out.Annual middle school student practise throwing and accident can occur, make us very headache.
In view of above-mentioned, the purpose of this utility model just provides a kind of alarming device that is used to throw equipment, to avoid in throwing casualty accident taking place.
For achieving the above object, the utility model is by the following technical solutions:
A kind of alarming device that is used to throw equipment comprises circuit board and power supply, it is characterized in that: soft-touch control, acceleration switch, trigger, logical circuit, delay circuit, electric vocalization device are housed on the circuit board, wherein:
Connect the input of trigger after soft-touch control and the acceleration switch series connection, the output of trigger connects delay circuit and electric vocalization device through logical circuit, and the output of delay circuit connects the input that resets of trigger.
In implementing measure of the present utility model:
Described soft-touch control is made of the unsettled transistor of base stage, two electric conductors that are connected with this transistorized base stage and collector respectively.
Described acceleration switch is to rock the contact-type switch.
Described electric vocalization device is made of loudspeaker and driver thereof.
Two inputs, two output logics that described logical circuit is made up of first not gate and the second not gate series connection, Sheffer stroke gate and the series connection of the 3rd not gate, wherein: the output of soft-touch control connects the input of first not gate, the output of first not gate and the output of trigger connect the input of Sheffer stroke gate, the output of second not gate connects the input of acceleration switch, and the output of the 3rd not gate connects delay circuit and electric vocalization device.
The utility model is fixed on to be thrown on the equipment.When soft-touch control and acceleration switch were all connected, trigger was set, and its output is blocked by logical circuit.After this if soft-touch control disconnects, then logical circuit allows the output of trigger to drive electric vocalization device, after one section time-delay, recovers former stationary state again.
The utility model has the advantages that: owing to only when two conditions of slipping out of the hand and move all satisfy, just send the caution sound, therefore not only can make the throwing equipment send the sound awing, with caution onlooker or pedestrian, and can unexpected sounding, can avoid the false alarm or the situation that disturbs residents to occur.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is circuit theory diagrams of the present utility model.
See also Fig. 1.The utility model comprises circuit board and power supply, and soft-touch control S1, acceleration switch S2, D flip-flop, logical circuit, delay circuit, electric vocalization device are housed on the circuit board.Connect the input end of clock of d type flip flop after soft-touch control S1 and the acceleration switch S2 series connection, the Q output of d type flip flop connects delay circuit and electric vocalization device through logical circuit, and the output of delay circuit meets the RESET input R of trigger.Wherein:
Soft-touch control S1 is made of the unsettled transistor T of base stage 1, two the electric conductor D1, the D2 that are connected with this transistorized base stage and collector respectively.Acceleration switch S2 rocks the contact-type switch, and this switch needs only and rocked and will connect, for example the switch of being made by spring or elastic sheet metal.Electric vocalization device is made of loudspeaker (or hummer) Y and driver T2 thereof.Delay circuit is made of resistance R 2 and R3, capacitor C 2.Two inputs, two output logics that logical circuit is made up of first not gate 1 and 2 series connection of second not gate, Sheffer stroke gate 3 and 4 series connection of the 3rd not gate.Wherein: the output of soft-touch control S1 connects the input of first not gate 1, the output of first not gate 1 and the Q of d type flip flop output connect the input of Sheffer stroke gate 3, the output of second not gate 2 connects the input of acceleration switch S2, and the output of the 3rd not gate 4 connects delay circuit and electric vocalization device.
The utility model is fixed in the cavity of discus internal layer, and other is thrown on the equipment also can be contained in grenade, javelin etc.Below in conjunction with throwing action its principle of work is described:
When soft-touch control S1 access failure, transistor T 1 ends because of no base stage bias current, even if this moment, acceleration switch S2 connected because of stressed, the low level of its emitter-base bandgap grading output also can't provide d type flip flop required triggering level, cause d type flip flop output still for low level can not drive loudspeaker Y sounding, this is stationary state.(that is to say in moving the process of throwing equipment,, no matter throw equipment and how to rock, can not send caution sound as long as hand does not contact S1.)
When the user contacts two the electric conductor D1 of soft-touch control S1 and D2 simultaneously with hand (the hand-held equipment of throwing this moment), transistor T 1 is because of there being base stage bias current conducting, and its emitter-base bandgap grading is exported high level.But do not keep off-state if S2 this moment is stressed, then d type flip flop also can keep former low level state.(that is to say, when hand contact S1, only otherwise move and throw equipment, also can not send caution sound.) if acceleration switch S2 this moment connects because of stressed, then this high level will be docked at capacitor C 1 charging of the clock end of d type flip flop via not gate 1 and 2, when the C1 current potential was charged to evoked potential, the Q of d type flip flop output just was turned into high level.But because the low level of not gate 1 output this moment makes not gate 4 still can not drive loudspeaker Y for low level to the blockade effect of Sheffer stroke gate 3.(this moment expression is hand-held throws equipment and it is imposed acceleration force, as do run-up, when rotating, waving action such as arm.)
After user's hand broke away from soft-touch control S1, the emitter-base bandgap grading output low level of T1 was just opened Sheffer stroke gate 3 through the high level of not gate 1 anti-phase output, so the output of the high level of d type flip flop drives loudspeaker Y sounding through Sheffer stroke gate 3, not gate 4.(the expression user will throw equipment and throw out.)
After this, the high level of not gate 4 outputs is to the charging of the delay capacitor C2 in the delay circuit, and through one section time-delay, when the current potential of C2 reached the reset level of d type flip flop, d type flip flop resetted, and loudspeaker Y stops sound.The utility model just recovers its initial stationary state.
From the above, this device adopts logical circuit, with motion with to slip out of the hand be two necessary conditions, only makes that when these two necessary conditions all possess, this device just sounding is warned, and meets the actual needs of throwing equipment in training fully.
Below only be preferred embodiment of the present utility model, anyly be equal to replacement based on of the present utility model, all should be within protection domain of the present utility model.
