Metal contact, two metal contact electrical connections are provided on two plugs on same straight line；It is provided in the middle part of the sheet body
The bottom end of mounting hole, bolt passes through mounting hole.
The pedestal in flakes of rotary plug-in type protection provided by the invention in flakes is equal in a circumferential direction as the center of circle using support mounting hole
8 jacks of even distribution are provided in two jacks on same direct direction and are provided with metal contact, metal contact with
Secondary circuit electrical connection；The sheet body in cross shape in flakes is inserted in rotation, is provided with plug on the ground of four terminals of cross,
Metal contact, two metal contact electrical connections are provided on two plugs being wherein located along the same line.
There are three states for tool in flakes for the protection of this rotary plug-in type, are investment respectively, exit and measure.When two bands in flakes are inserted in rotation
In flakes in two jacks with metal contact of pedestal, two band metal contacts in flakes are inserted in rotation at this time for the plug insertion of metal contact
Plug conducting pedestal in flakes secondary circuit, rotary plug-in type protection is in investment state in flakes；When rotation insert in flakes two without
The plug insertion of metal contact is in flakes in two jacks with metal contact of pedestal, rotation at this time insert in flakes two touched without metal
The plug of head shields the secondary circuit of pedestal in flakes, and rotary plug-in type protection is in flakes exits state；When rotation is inserted in flakes
Four plugs are not inserted into two jacks with metal contact of pedestal in flakes, at this time two of the pedestal in flakes of pedestal in flakes
Jack with metal contact exposes, and can just measure secondary circuit.
As a further preferred solution, it is provided with magnetic pole on the bottom end of the support mounting hole, bolt, it can be simply fast
Prompt changes the state of protection in flakes.
Compared with prior art, the beneficial effect of technical solution of the present invention is：
（1）A kind of protection of rotary plug-in type includes that pedestal and rotation are inserted in flakes in flakes, is equipped with 8 jacks on pedestal altogether, rotation is inserted and used in flakes
Cross form, so that protection has three state in flakes, is investment respectively, exits and measure.It puts into, exit state bottom
Seat jack closing, avoids the risk of electric shock；
（2）It is protected in flakes using rotary plug-in type entirely in entire protection screen, protective loop can only pass through support jack under measuring state
It measures, is avoided when measuring one by one because accidentally touching adjacent risk in flakes caused by intensively installing in flakes；
（3）There are mounting holes among protection in flakes is fixed on the base by bolt, for a long time when not used can remove in flakes protection；
（4）Static contact is arranged in both ends in flakes for protection, in contact inserted base jack, will realize that corresponding state turns by rotation
Become, it is simple and quick.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of device.
Fig. 2 is the side view of device.
Wherein：1. 2. jack of pedestal in flakes（Containing metal contact）3. 4. secondary circuit 5. of metal contact in jack
