Description
Technical field
This utility model relates to feedback circuit field, particularly relates to a kind of linkage feeding back fire resistant doorsets time of day
Door closer circuit.
Background technology
At present the linkage door closer of major part manufacturer production exist cannot feed back unlatching put in place, close put in place true
Signal (can only feed back door-closing in-place signal, it is impossible to feedback enabling puts in place signal), or descends nothing in off position
Method automatically powers off, and electric magnet is in the problems such as energising attracting state all the time, causes energy waste and the reset that pushes
Difficulty and fire resistant doorsets monitoring system can not correctly show fire resistant doorsets on off state thus to the normal use of fire resistant doorsets
Bring the situations such as hidden danger.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of feedback fire resistant doorsets true
The linkage door closer circuit of real state.
For achieving the above object, this utility model can be achieved by the following technical programs:
A kind of linkage door closer circuit feeding back fire resistant doorsets time of day, including the first resistance R1 parallel with one another
The first pin opening the monitoring switch SW1 that puts in place is connected with the second resistance R2, described first resistance R1, described
Opening the second pin ground connection of the monitoring switch SW1 that puts in place, its 3rd pin connects electromagnet coil A, described
Electromagnet coil A connects linkage door closer power supply；Described second resistance R2 connection closed puts in place monitoring switch SW2
The first pin, described closedown puts in place the second pin ground connection of monitoring switch SW2；Described first resistance R1 and
Second resistance R2 connects wire output.
Further, it is in series with and manually closes a button between described electromagnet coil A and linkage door closer power supply
SW3, described electromagnet coil A are connected with the first pin manually closing a button SW3, described linkage door closer
Power supply is connected with the second pin manually closing a button SW3.
Further, between described the second pin and the ground manually closing a button SW3, it is in series with the 3rd resistance R11,
Play the effect of current limliting.
Further, between described 3rd resistance R11 and ground, it is in series with LED LED1, is used for indicating work shape
State.
This utility model is serially connected in unlatching puts in place microswitch by fire resistant doorsets is opened the electromagnet coil of screens
Normal opened contact, simultaneously normally closed contact and after closing the normally closed contact series resistor of the microswitch that puts in place by one
Root feedback line output state, realizes closed mode lower electromagnet coil simultaneously and automatically powers off, push after putting in place from
Function is opened in dynamic adhesive again, compares traditional approach and has simple in construction, a feedback line output state, can feed back
Fire resistant doorsets truly open put in place, close put in place, internal fault status, automatically power off joint when being closed
Can, push and the feature such as easily open again.
Accompanying drawing explanation
Fig. 1 is circuit structure diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is further described:
As it is shown in figure 1, the linkage door closer circuit of feedback fire resistant doorsets time of day described in the utility model,
Mainly including the first resistance R1 parallel with one another and the second resistance R2, the first resistance R1 connects unlatching and puts in place prison
First pin of slowdown monitoring switch SW1, opens the second pin ground connection of the monitoring switch SW1 that puts in place, its 3rd pin
Connect electromagnet coil A, electromagnet coil A and connect linkage door closer power supply.Second resistance R2 connection closed
Put in place first pin of monitoring switch SW2, closes the second pin ground connection of the monitoring switch SW2 that puts in place.First
Resistance R1 and the second resistance R2 connects wire output, for the State-output of the door closer that links.Electromagnet coil
It is in series with between A and linkage door closer power supply and manually closes a button SW3, increase and manually close a function.Electric magnet
Loop A is connected with the first pin manually closing a button SW3, links door closer power supply and manually closes a button
Second pin of SW3 connects.Manually close and be in series with the 3rd resistance between the second pin and the ground of a button SW3
R11, plays current-limiting protection function.It is in series with LED LED1 between 3rd resistance R11 and ground, indicates work
State.
Operation principle:
Fire resistant doorsets are closed after putting in place, and the position slide block of linkage door closer is pressed in closedown and puts in place on monitoring switch SW2,
Close second pin of monitoring switch SW2 that puts in place, the 3rd pin Guan Bi, open and put monitoring switch SW1's in place
First pin, the second pin Guan Bi, the resistance that State-output is the first resistance R1 of linkage door closer, electromagnetism
Iron coil A power-off makes linkage door closer be in power save mode, realizes pushing easily opening function again simultaneously.
Fire resistant doorsets are opened after putting in place, and the position slide block of linkage door closer is pressed in unlatching and puts in place on monitoring switch SW1,
Open second pin of monitoring switch SW1 that puts in place, the 3rd foot Guan Bi, close the of the monitoring switch SW2 that puts in place
One pin, the second pin Guan Bi, the resistance that State-output is the second resistance R2 of linkage door closer, electric magnet
Loop A energising adhesive slide block cannot return, and makes fire resistant doorsets be in normally open.
When fire resistant doorsets i.e. do not have pass to put in place not reach, the position slide block of linkage door closer is in other positions,
Unlatching puts monitoring switch SW1 in place and closedown puts in place, and monitoring switch SW2 is the first pin, the second pin Guan Bi,
The State-output of linkage door closer is the first resistance R1 and the resistance in parallel of the second resistance R2, electric magnet simultaneously
Loop A power-off makes linkage door closer be in power save mode, real with the resistance of common port by calculating output port
Now judge fire resistant doorsets state and internal circuit failure state.
For a person skilled in the art, can be made other each according to above technical scheme and design
Kind corresponding change and deformation, and all these changes and deformation all should belong to this utility model right
Within the protection domain required.
