Road disposes the outer end of pipe, and the infrared human body inductive switch is placed in the outer end face of lockhole；When key is inserted into lockhole, key pair
Pressure switch is squeezed, pressure switch after being under pressure in an ON state, at the same time, hot outer human induction switch
Someone is sensed at doorway, infrared human body inductive switch is in an off state, and route is disconnected, hot outer human induction switch
It is at on-state when sensing doorway nobody, to make whole route in an ON state, buzzer, which makes a sound, to be mentioned
Show and extracts key in time；After extracting key, pressure switch rebound is disconnected, and buzzer stops sounding.
Preferably, it is provided with metal clips on the outside of the pressure switch, is provided with and presses on the inside of the metal clips
Power switchs corresponding jacking block, and the outer surface of the metal clips is coated with electric insulation layer.
Preferably, the pressure switch is placed in the end that route disposes pipe by the spring of a lateral arrangement.
Preferably, device of solar generating is additionally provided on the preventing key from not pulling device, needed for the buzzer sounding
Electric energy provided by the device of solar generating.
Compared with prior art, the beneficial effects of the present invention are:
1. it is of the invention novel in design reasonable, the warning device for forgetting to pull key, the dress are constituted by simply designing
Setting not will start when being inserted into key and people station on doorway, just will start when being inserted into key doorway nobody, both avoided
Unnecessary noise can also timely and effectively remind people in time to pull out key after opening the door or locking a door simultaneously, effectively avoid
Security risk has practicability outstanding.
2. the present invention is provided with elastic slice on the outside of pressure switch, and is electrically insulated in elastic slice with being coated on one side for key contact
Layer, the setting of the elastic slice of charged insulating layer not only can carry out effective protection to pressure switch, on the other hand also reduce key and lead
The security risk of electricity.
3. the pressure switch in the present invention is that the end of route placement pipe is placed in by the spring of a lateral arrangement,
It can avoid the case where key carries out excessive compression, pressure switch is avoided to be subject to crushing to pressure switch appearance.
4. being also provided with device of solar generating in the present invention, have the advantages that environmentally protective.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the electric operation control circuit figure of buzzer in the present invention.
In figure, buzzer 1, route disposes pipe 2, pressure switch 3, infrared human body inductive switch 4, lockhole 5, elastic slice 6, jacking block
7, power supply 8.
Specific embodiment
The present invention is described in further detail below in conjunction with Detailed description of the invention and specific embodiment mode.
Referring to Fig. 1 and Fig. 2, a kind of intelligent preventing key from not pulling device, including buzzer 1, route dispose pipe 2, pressure switch
3, infrared human body inductive switch 4 and power supply 8, buzzer 1, pressure switch 3, infrared human body inductive switch 4 and power supply 8 pass through route
Route in placement pipe 2 is cascaded, and pressure switch 3 is placed in the inner end of route placement pipe 2 and is located in lockhole 5, buzzing
Device 1 is placed in the outer end of route placement pipe 2, and infrared human body inductive switch 4 is placed in the outer end face of lockhole 5；It is inserted into and locks in key
When hole 5, key squeezes pressure switch 3, pressure switch 3 after being under pressure in an ON state, it is at the same time, hot
