Abstract
A kind of safety switch, including lock body (1), it is characterized in that, lock body (1) includes key (2), locking system (3) and closer (4), wherein, the locking system (3) is connected with closer (4).The utility model is solved due to avoiding forcing disconnection or maloperation deenergization device systems can be caused to damage, and simple in construction, securely and reliably.
Description
Technical field
It the utility model is related to device power supply (DPS) protection field, more particularly to a kind of safety switch.
Background technology
In the prior art, most of Medical Devices set a main switch, and main switch is typically controlled with key mechanical.By key
Spoon come control plant-grid connection, disconnect.If however, disconnection or maloperation deenergization is forced to cause to set in device systems operation
Standby system failure.
Utility model content
To overcome the drawbacks described above of prior art, the utility model provides a kind of safety switch, including lock body, wrapped in lock body
Key, locking system and closer are included, wherein, the locking system is connected with closer.
The locking system includes locking bolt and conductive switch, wherein, locking bolt is connected with conductive switch, and conduction is opened
Pass is connected with closer.
The closer is connected with relay, and relay is connected with USB port.
So by control of the locking system in lock body to key turns, avoid forcing when ensuring that device systems operation
Disconnect or maloperation deenergization can cause device systems to damage.
Brief description of the drawings
Fig. 1 is safety switch schematic diagram.
Embodiment
A kind of safety switch provided by the utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 goes out, a kind of safety switch, including lock body 1, and lock body 1 includes key 2, locking system 3 and closer 4, its
In, the locking system 3 is connected with closer 4.
The locking system 3 includes locking bolt 31 and conductive switch 32, wherein, locking bolt 31 is connected with conductive switch 32
Logical, conductive switch 32 is connected with closer 4.
The closer 4 is connected with relay 5, and relay 5 is connected with USB port 6.
In the course of work, when device systems are in opening, USB port 6 is powered and believed to the input high level of relay 5
Number, the high level signal is identified and is powered with closer 4 by starting relay 5, and closer 4 connects conductive switch 32 and starts lock
Only bolt 31, locking bolt 31 rise and on the tracks that key bit 21 rotates, and prevent key from rotating.Device systems, which are in, closes shape
During state, the energization dead electricity of USB port 6, by after the signal identification, closer 4 connects conductive switch 32 and closes lock starting relay 5
Only bolt 31, locking bolt 31 decline, key rotary closing master switch.It ensure that the security of equipment operation.
The utility model is solved due to avoiding forcing disconnection or maloperation deenergization device systems can be caused to damage, and
And it is simple in construction, securely and reliably.
Finally it should be noted that above example is only describing the technical solution of the utility model rather than to this technology
Method is limited, and the utility model can above extend to other modifications, change, application and embodiment in application, and because
This thinks all such modification, change, application, embodiments all in the range of spirit or teaching of the present utility model.
