Further, the attention device includes the buzzer connecting with the microprocessor signals end
In order to better understand and implement, the invention will now be described in detail with reference to the accompanying drawings.
Detailed description of the invention
Fig. 1 is the main view of door lock state detection device of the present invention；
Fig. 2 is door lock state detection device overhead sectional view of the present invention.
Specific embodiment
It is the main view of door lock state detection device of the present invention please refer to Fig. 1 and Fig. 2, Fig. 1；Fig. 2 is door of the present invention
Lock status detection device overhead sectional view.The door lock state detection device, including inductive switch 1, microprocessor (not shown),
Bracket 2, cylinder 3, piston rod 4 and attention device (not shown).
The inductive switch 1 is electrically connected with the microprocessor.The bracket 2 is fixed on door leaf 6；The cylinder 3
It is arranged on the bracket 2 and is connect with the signal end of the microprocessor；The cylinder 3 includes cylinder block 31 and is placed in gas
The intracorporal piston 32 of cylinder cylinder；The piston rod 4 runs through the cylinder block 31, and the bar tail of the piston rod connects the piston
32；The head of the piston rod 4 is towards doorframe 5, and the head of the piston rod 4 is against doorframe 5 when the door leaf 6 closes
On.The attention device is connect with the signal end of the microprocessor.
In the present embodiment, the inductive switch 1 includes magnetic switch 11 and magnetic patch 12.The magnetic switch 11 is embedded at door
It is electrically connected on the side of frame 5 and with the input terminal of the microprocessor；The magnetic patch 12 is arranged on 6 side of door leaf and in door leaf
6 is opposite with the magnetic switch 11 when closing, to trigger the on-off of the magnetic switch 11.When door leaf 6 closes, the magnetic patch
12, which trigger the magnetic switch 11, connects, and connects using the magnetic switch 11 as the route of contact, there is signal at the inductive switch end
It is sent to the microprocessor；It when door leaf 6 is opened, is disconnected using the magnetic switch 11 as the route of contact, the induction is opened
Then no signal is sent to the microprocessor for pass 1
The cylinder 3 receives the signal that the microprocessor is sent and controls the piston rod 4 and pushes away toward 5 direction of doorframe
Out, the piston rod 4 arrives on doorframe 5, while applying certain active force to doorframe 5, and doorframe 5 is made by the piston rod 4
Reaction force also is generated to piston rod 4 while firmly；After the door leaf 6 closes, the mechanical code lock 7 still in semi-locking and
When not locking really, piston rod 4 is pushed open by the reaction force of doorframe 5, and door leaf 6 is driven to open.
In the present embodiment, the active force and doorframe 5 that piston rod 4 is applied to doorframe 5 are to the size of the reaction force of piston rod 4
It can be adjusted by the way that cylinder location is arranged, so that the active force of the piston rod 4 will not both damage doorframe 5 and door leaf 6, doorframe 5
Reaction force can push the door leaf 6 for being left unlocked or unlatched false lock open.Reach the scheduled time when the time that the piston rod 4 arrives on doorframe 5,
And door leaf 6 illustrates that door is real locking when not pushed open yet by the reaction force of doorframe 5, the cylinder 3 receives the micro process
The order of device, control piston rod 4 retract；After the piston rod 4 arrives on doorframe 5, reaction force of the door leaf 6 by doorframe 5
When pushing open, illustrate that door leaf 6 is in semi-locking state, door leaf 6 is not locked really, and the cylinder 3 receives the microprocessor, control
Piston rod 4 retracts.
To save the power of driving piston rod 4, while damage of the piston rod 4 to doorframe 5 is reduced, the door lock state inspection
Device further includes a reset spring (not shown), and the reset spring is set in 4 end of piston rod, and after door leaf 6 is closed
Vertically doorframe 5.
The attention device includes the flash lamp and buzzer connecting with the microprocessor signals end.
The microprocessor constantly detects the signal of 1 on-off of inductive switch, when door leaf 6 closes, when microprocessor detects
When connecting to inductive switch 1, the cylinder 3 is transmitted a signal to；After the cylinder 3 receives signal, piston rod 4 is controlled toward doorframe
5 directions are released, and the piston rod 4 arrives on doorframe 5 and apply to doorframe 5 certain active force, and doorframe 5 is made by piston rod 4
Reaction force also is generated to piston rod 4 while firmly, when the time that the piston rod 4 arrives on doorframe 5 reaching scheduled
Between, and when door leaf 6 is not pushed open by the reaction force of doorframe 5 yet, illustrate that door is real locking, the microprocessor sends signal
Control cylinder 3 retracts piston rod 4；After the piston rod 4 arrives on doorframe 5, door leaf 6 is pushed by the reaction of doorframe 5
When opening, when illustrating that door leaf 6 is in semi-locking state, door leaf 6 is not locked really, at this time since door leaf 6 is open, the micro process
Device detects to be disconnected after inductive switch 1 is connected, then transmits a signal to flash lamp and buzzer, the flash lamp is bright, the buzzing
Device ring, warning operator's door lock are unlocked.
Compared with the prior art, the present invention makes gas using the cylinder being arranged on door leaf and the piston rod perpendicular to doorframe
Cylinder drives piston rod to apply active force to doorframe when door leaf closes, and then under the reaction force of doorframe, will be in false lock shape
Alarm signal is pushed and issued to the door leaf of state open, is equivalent to and is shutting behind the door, people exert oneself sliding door leaf detection door leaf it is whether real
The operation of locking effectively avoids the occurrence of the problem of door leaf vacation is locked.
The invention is not limited to above embodiment, if not departing from the present invention to various changes or deformation of the invention
Spirit and scope, if these changes and deformation belong within the scope of claim and equivalent technologies of the invention, then this hair
It is bright to be also intended to encompass these changes and deformation.
