Description
Technical field
The utility model discloses a kind of insulating barrier that can quickly remove detected object contact surface, tests grounding resistance
Or the lightning protection test pen of transition resistance value.Belong to lightning protection detection device technical field.
Background technology
The test pen for being presently used for testing grounding resistance or transition resistance is the stainless steel stub of tip.Needed before test
The surface of detected object is polished, removes paint and rusty stain.After being handled, detected object is in close contact with nib
Surface, pass through instrument and meter survey measurements.
The operating method mainly has following deficiency：First, paint removal derusting is wasted time and energy, detection efficiency is influenceed.Second, paint removal removes
Rust is not thorough, it is possible to causes detection numerical value bigger than normal, causes to misread.Therefore, there is an urgent need to one kind can be rapidly completed above-mentioned behaviour
The equipment of work, solves the deficiency of the operating method at present.
The content of the invention
For the deficiency of prior art, the purpose of this utility model, which is to provide, a kind of has polishing derusting and data test concurrently
Lightning protection test pen, polishing detection synchronous integrated is realized, can quickly be polished, and can is accurately tested.
The technical solution of the utility model is shown as using the polishing test nib with rotary power head, disposably will be tested
The surface of point is quickly cleaned out, and realizes that zero resistance contacts, while forms detection link circuit, completes detection reading.
The purpose of this utility model can be achieved by the following technical programs.
Drive device including motor, battery and switch composition provides power for work head；Connect the fixture of machine shaft
And the work head of polishing nib composition quickly clears up measured object surface；Connect the test lead composition of motor metal-back and binding post
Measure loop synchronously complete detection；And portable shell and the tail plug for changing battery.
The utility model is provided with switch, for cutting off or connecting the power supply circuit of motor.Switch is opened, circuit is connected, electricity
Pond motor, the quick rotation of polishing nib is driven by fixture, can quickly remove the corrosion layer or skin of paint of metal surface.
Polishing nib, fixture, machine shaft, motor metal-back and test lead and binding post form galvanic circle, and binding post is used for
Connect measuring instrument and complete detection.Shell can protect internal circuit, while have insulation protection.Tail plug can be opened,
For changing battery or repair circuit.
In summary, a kind of lightning protection test pen, it is characterized in that the driving dress including motor, battery and controlling switch composition
Put；The polishing nib for connecting the fixture of machine shaft and being connected with fixture；The test of connection motor metal-back and binding post is led
The measure loop of line composition；And the shell of motor, controlling switch and battery is accommodated, and binding post is installed for closure
Tail plug.
Described polishing nib is made up of with machine shaft fixture and electrically connected；
Described motor metal-back is made up of with machine shaft motor oiliness bearing and electrically connected.
The utility model has advantages below：
1st, there is polishing function, paint removal can quickly derust, reduce the process originally polished with file or sand paper；
2nd, the surface of a wound is small, and polishing effect is good, and test error is small.Due to metal body can be completely exposed, reduce to greatest extent
Systematic error；
3rd, polishing, the time is short, and the polishing mode only needs the several seconds, and the used time shortens more than half；
4th, polish and detect and once complete simultaneously, easy to operate, test is accurate, is easy to carry；
5th, battery can be changed, simple in construction, and maintenance cost is cheap.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
In figure：1- polishing nibs；2- motors；3- controlling switches；4- shells；5- pilots；6- tail plugs；7- binding posts；

The measure loop of composition；And the shell 4 of motor 2, controlling switch 3 and battery 9 is accommodated, and wiring is installed for closure
The tail plug 6 of post.
Described polishing nib 1 is made up of with machine shaft fixture 11 and electrically connected；
Described motor metal-back is made up of with machine shaft motor oiliness bearing and electrically connected.
The composition in specific each portion is as follows：Motor uses 3.7V direct current generators, and battery uses 3.7V cylindrical lithium batteries, and fixture is adopted
With miniature drill chuck.
As shown in Figure 1, circuit of the present utility model is broadly divided into two parts, first, control circuit：The connection control of controlling switch 3
Wire 5 processed, one end connection electrode negative, one end connects GND by spring 8.Anode and motor positive pole pass through spring
Compress.Second, test circuit：The one end of test lead 10 connects binding post 7, one end connection motor metal-back, and motor metal-back passes through
Fixture 11 is formed with polishing nib 1 and electrically connected.During test, polishing nib forms path with test lead, and instrument is connected by binding post
Device is tested.
The utility model connects circuit by switch 3 first, and the drive motor 2 of battery 9 rotates, and is driven and polished by fixture 11
Nib 1 is polished, and the metal valley in polishing nib 1 can quickly polish off the corrosion layer or skin of paint of metal surface.Polishing
After the completion of, make polishing nib 1 and the metal covering good contact exposed, you can carry out the test of grounding resistance or transition resistance.
