Technical field
The present invention relates to a kind of devices of preventing key from not pulling, belong to warning device technical field.
Background technique
People often forget to pull out key in lockhole after enabling in daily life, and this phenomenon is in the elderly
It is especially common in group.Forget that a key is pulled out, also often bring no small puzzlement to people's lives, because for most
Forget to pull key for number people and be likely to cause the loss of key, some criminals, which can utilize, forgets that the key pulled out is entered the room steathily
Surreptitiously, damage to property is caused, even if key, which is not lost, will also result in many troubles.
Summary of the invention
It, should the purpose of the present invention is in view of the above-mentioned drawbacks in the prior art, providing a kind of device of preventing key from not pulling
Device can timely and effectively remind people in time to pull out key after opening the door or locking a door, and effectively prevent security risk, tool
There is practicability outstanding.
To achieve the above object, the technical solution of the invention is as follows:
A kind of preventing key from not pulling device, including buzzer, route placement pipe, pressure switch, elastic slice and jacking block, the bullet
Piece is placed in lockhole, and the jacking block is placed on the inside of elastic slice, and with the pressure switch pair that is placed in route placement tube end
It answers, the route in the route placement pipe is directly connected with power supply；When key is inserted into lockhole, key carries out elastic slice
It squeezes, and then squeezes jacking block to pressure switch, pressure switch then connects route after being under pressure, and buzzer issues
Auditory tone cues extract key in time；After extracting key, elastic slice rebound, jacking block no longer oppresses pressure switch, pressure switch
It disconnects, buzzer stops sounding.
Preferably, 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 can timely and effectively remind people to extract key in time after opening the door or locking a door, and can effectively avoid the feelings entered the room by thief
Condition 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, lockhole 4, elastic slice 5, jacking block 6, power supply 7.
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 preventing key from not pulling device, including buzzer 1, route dispose pipe 2, pressure switch 3, bullet
Piece 5 and jacking block 6, elastic slice 6 are placed in lockhole 4, and jacking block 6 is placed in 5 inside of elastic slice, and disposes 2 end of pipe with route is placed in
Pressure switch 3 it is corresponding, the route in route placement pipe 2 is directly connected with power supply；When key is inserted into lockhole 4, key
Spoon squeezes elastic slice 6, and then squeezes jacking block 6 to pressure switch 3, and pressure switch 3 is after being under pressure then by line
Road is connected, and buzzer makes a sound prompt and extracts key in time；After extracting key, elastic slice 5 is sprung back, and jacking block 6 no longer opens pressure
It closes 3 to be oppressed, pressure switch 3 disconnects, and buzzer 1 stops sounding.
The outer surface of metal clips 5 is coated with electric insulation layer as a preferred technical solution, avoid key directly with it is logical
Electric line is connected, and can effectively avoid electric shock.
Pressure switch 3 is placed in route by the spring of a lateral arrangement and disposes pipe 2 as a preferred technical solution,
End can avoid the case where key carries out excessive compression, pressure switch is avoided to be subject to crushing to pressure switch appearance.
Device of solar generating, 1 sounding of buzzer are additionally provided on preventing key from not pulling device as a preferred technical solution,
Required electric energy is provided by the device of solar generating, energy conservation and environmental protection.
Embodiment 1:
As depicted in figs. 1 and 2, a kind of preventing key from not pulling device, including buzzer 1, route placement pipe 2, pressure switch 3,
