In order to understand better and implement, describe the utility model in detail below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model door lock state checkout gear;
Fig. 2 is the utility model door lock state checkout gear vertical view cutaway drawing.
Detailed description of the invention
Please refer to the front view that Fig. 1 and Fig. 2, Fig. 1 are the utility model door lock state checkout gears; Fig. 2 is the utility model door lock state checkout gear vertical view cutaway drawing.This door lock state checkout gear, comprises inductive switch 1, microprocessor (not shown), support 2, cylinder 3, piston rod 4 and attention device (not shown).
The electrical connection of described inductive switch 1 and described microprocessor.Described support 2 is fixed on door leaf 6; Described cylinder 3 to be arranged on described support 2 and to be connected with the signal end of described microprocessor; The piston 32 that described cylinder 3 comprises cylinder block 31 and is placed in cylinder block; Described piston rod 4 runs through described cylinder block 31, and the bar tail of described piston rod connects described piston 32; The bar head of described piston rod 4 is towards doorframe 5, and the bar head of described piston rod 4 is against on doorframe 5 when described door leaf 6 closes.Described attention device is connected with the signal end of described microprocessor.
In the present embodiment, described inductive switch 1 comprises magnetic switch 11 and magnetic patch 12.The side that described magnetic switch 11 is embedded at doorframe 5 is electrically connected with the input of described microprocessor; Described magnetic patch 12 to be arranged on door leaf 6 side and relative with described magnetic switch 11 when door leaf 6 closes, to trigger the break-make of described magnetic switch 11.When door leaf 6 closes, described magnetic patch 12 triggers this magnetic switch 11 and connects, and connects using this magnetic switch 11 as the circuit of contact, and described inductive switch end has signal to be sent to described microprocessor; When door leaf 6 is opened, disconnect using this magnetic switch 11 as the circuit of contact, described inductive switch 1 no signal is sent to described microprocessor
Described cylinder 3 receives signal that described microprocessor sends and controls described piston rod 4 and release toward described doorframe 5 direction, described piston rod 4 arrives on doorframe 5, apply certain active force to doorframe 5, doorframe 5 also produces reaction force to piston rod 4 while being subject to described piston rod 4 active force simultaneously; After described door leaf 6 closes, this mechanical code lock 7 be still in semi-locking and really do not lock time, the reaction force that piston rod 4 is subject to doorframe 5 is pushed open, drive door leaf 6 open.
In the present embodiment, the size that piston rod 4 is applied to the active force of doorframe 5 and the reaction force of doorframe 5 pairs of piston rods 4 regulates by arranging cylinder location, make the active force of this piston rod 4 both can not damage doorframe 5 and door leaf 6, the door leaf 6 being left unlocked or unlatched false lock can be pushed open by the reaction force of doorframe 5.Reach predetermined time when the time that described piston rod 4 arrives on doorframe 5, and when door leaf 6 is pushed open by the reaction force of doorframe 5 not yet, illustrate that door has really been locked, described cylinder 3 receives the order of described microprocessor, and control piston bar 4 is retracted; When described piston rod 4 arrives to after on doorframe 5, when the reaction force that door leaf 6 is subject to doorframe 5 is pushed open, illustrate that door leaf 6 is in semi-locking state, door leaf 6 is not really locked, and described cylinder 3 receives described microprocessor, and control piston bar 4 is retracted.
For saving the power of piston rod 4, reduce the damage of piston rod 4 pairs of doorframes 5 simultaneously, described door lock state testing fixture also comprises a back-moving spring (not shown), and described back-moving spring is set in piston rod 4 end, and after door leaf 6 is closed vertically doorframe 5.
Described attention device comprises the flash lamp and buzzer that are connected with described microprocessor signals end.
Described microprocessor constantly detects the signal of inductive switch 1 break-make, when door leaf 6 closes, when microprocessor detects that inductive switch 1 is connected, transmits a signal to described cylinder 3; After described cylinder 3 receives signal, control piston bar 4 is released toward doorframe 5 direction, described piston rod 4 to arrive on doorframe 5 and applies certain active force to doorframe 5, doorframe 5 also produces reaction force to piston rod 4 while being subject to piston rod 4 active force, predetermined time is reached when the time that described piston rod 4 arrives on doorframe 5, and door leaf 6 is when being pushed open by the reaction force of doorframe 5 not yet, illustrate that door has really been locked, described microprocessor sends signal control cylinder 3 and is retracted by piston rod 4; When described piston rod 4 arrives to after on doorframe 5, when the reaction force that door leaf 6 is subject to doorframe 5 is pushed open, when illustrating that door leaf 6 is in semi-locking state, door leaf 6 is not really locked, and now because door leaf 6 is open, described microprocessor detects that rear disconnection connected by inductive switch 1, then transmit a signal to flash lamp and buzzer, described flash lamp is bright, described buzzer rings, and warning operating personnel door lock is unlocked.
Compared to prior art, the utility model utilizes the cylinder that is arranged on door leaf and the piston rod perpendicular to doorframe, cylinder piston rod when door leaf closes is made to apply active force to doorframe, and then under the reaction force of doorframe, the door leaf being in false lock status is pushed open and sends alarm signal, be equivalent to shutting behind the door, people's sliding door leaf of exerting oneself detects the door leaf operation of whether really locking, and effectively avoids the problem occurring door leaf vacation lock.
The utility model is not limited to above-mentioned embodiment, if do not depart from spirit and scope of the present utility model to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these changes and distortion.
