Description
Technical field
The present invention relates to a kind of distribution box.
Background technology
For safety and easy to control, the part such as switch is typically assembled into distribution box.In the poor operating mode of environment
Under, easily there is electric leakage, loose contact etc. situation in the circuit in distribution box, or even can cause fire.Once feelings of causing danger
Condition is, it is necessary to which neighbouring personnel open rapidly the chamber door of distribution box to be handled.But, usually for the sake of security, chamber door is all
Lock, therefore the operating personnel without key can be hindered to open distribution box, easily trigger more serious accident.
The content of the invention
The purpose of the present invention is to propose to one kind internally cause danger situation when, the peace of distribution box door can be easy to open
Full distribution box.
The safe power distribution box of the present invention includes casing and chamber door, and key is the side side wall of the casing provided with installation
Cylinder, the mounting cylinder is towards the one end open of chamber door, and the side wall of mounting cylinder is provided with fixing hole；The chamber door is provided with hinge, institute
State hinge by rotation support portion, fixed support portion and connection rotation support portion, fixed support portion rotating shaft constitute, the chamber door with
Rotation support portion is fixedly connected, and the fixed support portion is provided with mounting post, and the mounting post is inserted into by the openend of mounting cylinder
In mounting cylinder, the position of mounting post correspondence fixing hole is provided with pin hole, and mounting post utilizes through fixing hole and is inserted into pin hole
Interior iron pin is fixedly connected with mounting post；Compressive state is folded between the head of a nail of the pin and the outer wall of mounting cylinder
Spring；The casing is provided with electromagnet at the opposite of fixing hole, and the electromagnet is connected with a controller, the controller
It is connected with Smoke Sensor and/or current sensor.
The operation principle of above-mentioned safe power distribution box is as follows：
Distribution box power supply power no excessively stream in normal and distribution box, catch fire when, controller control electromagnet
It is powered, the magnetic of electromagnet applies suction to iron pin, pin is overcome the elastic force of compression spring and is stable in pin hole,
Now mounting post can not deviate from the presence of pin, so that the rotation support portion of hinge is fixedly connected with wall box,
Chamber door can only be opened with the mode of opening box door lock, rotation chamber door.
When occurring excessively stream in distribution box, catching fire, controller control electromagnet power-off, the magnetic of electromagnet disappears
Lose, pin is deviate under the elastic force effect of compression spring out of pin hole, and mounting post is without the restriction effect of pin, Ke Yicong
Freely deviate from mounting cylinder, now chamber door directly can be extracted and opened together with hinge, without opening case using key
Door lock.
When the power supply in distribution box is powered off, electromagnet naturally without magnetic, now chamber door can directly together with
Hinge is extracted and opened together, without opening box door lock using key.
Specifically, the controller includes single-chip microcomputer and relay, and a control end of the relay is grounded, another
Individual control end is connected with the output pin of corresponding single-chip microcomputer；One lead-out terminal of relay is used to be connected with power supply, another
Lead-out terminal is grounded by electromagnet.Single-chip microcomputer comes whether control relay inhales by exporting low level or high level signal
Close, so that whether the electromagnet for controlling the relay to be connected is powered.
Further, the mounting cylinder is provided with anti-delinking part in the side of fixing hole, and the anti-delinking part is by one section of groove closed
Body is constituted, and the cell body connects with fixing hole；The head of a nail and compression spring of the pin are respectively positioned in cell body.When electromagnet power-off
And when losing magnetism, compression spring promotes pin from pin hole from inside to outside, until the blind end of lug cap and cell body offsets, this
Sample just while limitation of the releasing pin to mounting post, can avoid pin from being bound to other positions and cause new dangerous situation.
Further, for ease of the inner case of observation distribution box, the chamber door at least part is transparent.
The safe power distribution box of the present invention can be caught fire, excessively stream or power supply are lost by improving hinge in distribution box
During the dangerous situations such as electricity, chamber door can be opened without opening box door lock, valuable time is improved to recover, with good peace
Quan Xing.
