Compared with the prior art, the beneficial effects of the utility model are that, whether the measured object that can test operation space big, do not have and shelter from is electrified when, can also measure that operation space is little, whether the measured object that has the shelter from is electrified, simple structure.
Description
Technical Field
The utility model relates to a test electricity device, especially a flexible low pressure electrography of testing of extension that indicating voltage exists.
Background
At present, the known test pencil structure is formed by connecting a test contact, a current-limiting resistor, a neon tube, a metal spring and a hand contact electrode in series. The test contact is contacted with the tested object, the hand touches the hand touch electrode, when the tested object has relatively high voltage, the neon tube is lighted, which shows that the tested object is electrified.
However, in many cases, whether an electrified detected point is shielded by an obstacle or in a narrow space around the position, the obstacle needs to be moved when the position needs to be measured, and people are easily shocked or equipment is easily damaged in the moving process.
Disclosure of Invention
The utility model aims at overcoming the current inconvenient not enough that is sheltered from or the narrow and small position in space of touching of test pencil, providing a flexible low pressure test pencil of extension, should test the function that the test pencil can not only satisfy ordinary test pencil, can conveniently detect behind the barrier or the difficult station of treating that touches such as the narrow and small space moreover.
In order to achieve the purpose, the utility model is implemented according to the following technical scheme:
the utility model provides an electrography is tested to flexible low pressure of extension, includes the test contact of testing the electrography main part and being connected with testing the electrography main part, the test contact is flexible and the insulated metal hose that can stereotype, insulated metal hose comprises metal hose and the flexible insulated metal hose of cladding outside the metal hose, one section metal hose of barely exposing of insulated metal hose's front end is as electrography test contact head, metal hose is connected with testing the electrography main part electricity in insulated metal hose's the rear end.
Further, test electrography main part and include insulating casing and set up current-limiting resistor, neon tube, spring and the hand electrode of touching in insulating casing, current-limiting resistor fixes the front end in insulating casing, metal collapsible tube is connected with the current-limiting resistor front end in insulating metal collapsible tube's the rear end, and current-limiting resistor's rear end is connected with neon tube one end, and the neon tube other end is connected with spring one end, and the spring other end is connected with the one end of touching the motor by hand, and the hand is touched the motor and is located insulating casing rear end.
Preferably, the flexible gold hose is a copper tube, and the flexible insulation hose is a silicone tube.
The utility model discloses change the structure of test contact, make test contact with elongated flexibility, insulating metal collapsible tube that can stereotype, the front end is naked metal collapsible tube as electrography test contact head, and whether it is electrified can twist into different shapes as required to measure to test the electrography contact when needs inspection are narrow and small, have the position of sheltering from, and other measurement requirements are the same with ordinary neon tube-type test electrography principle.
Compared with the prior art, the beneficial effects of the utility model are that, whether the measured object that can test operation space big, do not have and shelter from is electrified when, can also measure that operation space is little, whether the measured object that has the shelter from is electrified, simple structure.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be further described with reference to the drawings and specific embodiments, illustrative embodiments and description of which are provided herein to explain the invention, but not as a limitation thereof.
As shown in fig. 1, the flexible low pressure electrography of testing of extension of this embodiment is including testing electrography main part 1 and with test contact 2 that electrography main part 1 is connected, test contact 2 is flexible and insulating metal hose that can stereotype, insulating metal hose comprises metal hose 4 and the flexible insulating hose 3 of cladding outside metal hose 4, and metal hose 4 can be the copper pipe, and the copper pipe has good electrical property to, and flexible insulating hose 3 can be the silicone tube, and the silicone tube has good insulating properties, the naked one section metal hose 4 of exposing of front end of insulating metal hose is as electrography test contact, metal hose 4 is connected with test electrography main part 1 electricity in insulating metal hose's the rear end, and insulating metal hose's length can be formulated as required.
Further, test pencil main part 1 and include insulating casing 5 and set up current-limiting resistor 6, neon tube 7, spring 8 and hand touch electrode 9 in insulating casing 5, current-limiting resistor 6 fixes the front end in insulating casing 5, metal hose 4 is connected with current-limiting resistor 6 front end in insulating metal hose's the rear end, and current-limiting resistor 6's rear end is connected with 7 one end of neon tube, and the 7 other end of neon tube is connected with 8 one end of spring, and the 8 other ends of spring are connected with the one end of hand touch motor 9, and hand touch motor 9 is located insulating casing 5 rear end.
The utility model discloses during the use, can directly use the metal collapsible tube 4 that exposes out of front end to test, it is narrow and small, whether have the position of sheltering from electrified can twist into different shapes as required to test the electrography contact and measure when needs inspection.
The technical scheme of the utility model is not limited to the restriction of above-mentioned specific embodiment, all according to the utility model discloses a technical scheme makes technical deformation, all falls into within the protection scope of the utility model.
