Description
Technical field
The utility model belongs to magnetic down techniques field more particularly to a kind of electronic device magnetism cut-off switch.
Background technique
Currently, the prior art commonly used in the trade is such that
Currently, needing the frequent open state of fire resistant doorsets in some places such as office, office building to facilitate leading to for people
Row, but most of fire resistant doorsets doors, by the unlatching of magnet absorption holding door, magnet contact area is less when installation, and magnetic force is poor,
It is easy to cause the closing of door, interim, the progress that cannot easily close the door and alarm are come in fire.
In conclusion problem of the existing technology is:
Most fire resistant doorsets doors adsorb the unlatching for keeping door by magnet, and magnet contact area is less when installation, and magnetic force is poor,
It is easy to cause the closing of door, interim, the progress that cannot easily close the door and alarm are come in fire.
Summary of the invention
In view of the problems of the existing technology, the utility model provides a kind of electronic device magnetism cut-off switch.
The utility model is realized in this way a kind of electronic device magnetism cut-off switch, is provided with electromagnet；
The electromagnet is movably arranged on upper shell by shaft one, and shell side screw is fixed with alarm device,
Alarm device lower end is linked with switch, and outer casing bottom screw is fixed with fixed plate one；
Fixed plate two is flexibly connected by shaft with magnet.
Further, the housing outward end is connected with power supply line, and power supply line connects electromagnet, alarm device, switch by conducting wire.
Further, the fixed plate one is provided with rounded groove with surrounding in fixed plate two, and fluting will be fixed by screw
Plate one is fixed with fixed plate two.
Further, the switch is connect with electromagnet, alarm device conducting wire, electromagnet and the mutual magnetic of magnet.
The advantages of the utility model and good effect are as follows:
Door is carried out magnetic by electromagnet by the utility model, keeps normal opening state, fire comes temporarily, disconnected by lower switch
Electromagnet is opened, while alarm device sounds an alarm, closes fire resistant doorsets, personal safety as well as the property safety has been effectively ensured.
The utility model advanced design, compact is easy for installation, and using reliable, power consumption is small, has effectively protected people's
Property safety

Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing.
As depicted in figs. 1 and 2, the utility model embodiment electronic device magnetism cut-off switch includes: electromagnet 1, shell
2, shaft 1, power supply line 4, alarm device 5, switch 6, fixed plate 1, fixed plate 28, shaft 29, magnet 10.
The electromagnet 1 is movably arranged on 2 upper end of shell by shaft 1, and the 2 side screw of shell is fixed with alarm
Device 5,5 lower end of alarm device are linked with switch 6, and 2 lower screws of shell are fixed with fixed plate 1；
Fixed plate 28 is flexibly connected by shaft 9 with magnet 10.
2 outer end of shell is connected with power supply line 4, and power supply line 4 connects electromagnet 1, alarm device 5, switch 6 by conducting wire.It is fixed
Surrounding is provided with rounded groove on plate 1 and fixed plate 28, and fluting is consolidated fixed plate 1 and fixed plate 28 by screw
It is fixed.Switch 6 is connect with electromagnet 1,5 conducting wire of alarm device, electromagnet 1 and the mutual magnetic of magnet 10.
Working principle of the utility model is:
Electromagnet is fixed on fireproof door frame by fixed plate 1, is fixed on magnet 10 relatively by fixed plate 28
On the wall answered, power supply line 4 is connected into power supply, the angle of shaft 1 and shaft 29 is adjusted, so that electromagnet 1 (MFZ1-4.5)
It is connect with the mutual magnetic of magnet 10；When by lower switch 6 (FL4-25), (MFZ1-4.5) power supply of electromagnet 1 is disconnected, alarm device 5
(N2018010901) power supply is connected, and is sounded an alarm with watchful internal staff.
The above is only the preferred embodiment to the utility model, is not made in any form to the utility model
Limitation, it is all according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations with
Modification, is all within the scope of the technical scheme of the utility model.
