Existing electroscope carries out independent electrical verification work only, and the operation of follow-up connection ground wire also needs artificial outlet or suspention, throwing to install.These two kinds of operations need independently to carry out respectively, and operational sequence complexity, operating personnel's labour intensity increase, reduced the security of operating personnel's operation.
The utility model content
The utility model provides a kind of electroscopic device at above-mentioned the deficiencies in the prior art, can carry out work such as electrical verification and ground wire installation simultaneously, increases work efficiency, and improves operating personnel's security.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of electroscopic device, comprise electrical verification contact, electroscope, expansion link and earthing device, described electrical verification contact is fixed on electroscope one end, and the described galvanoscopic other end is connected on the expansion link; Described earthing device comprises the conductor wire end that is connected with ground wire, and described conductor wire end is made as the clamp shape, and its rear end is provided with the through hole of the movable connection of electrical verification contact.
Preferably, described electroscope and expansion link are for being threaded.
Preferably, described electrical verification contact is made as the clamp shape, is that rotating shaft is connected with electroscope, and the width of described electrical verification contact is less than the width of conductor wire end through hole.
Preferably, with the expansion link junction, described electroscope is made as internal thread and external thread; Described expansion link is provided with external thread.
Preferably, the end of described expansion link is provided with the internal thread that is connected with the electroscope external thread.
Compared with prior art, the advantage that the utlity model has: adopt telescopic electroscope and ground wire to unite use, after electrical verification, utilize described electroscope that described ground wire conductor wire end is installed on the lead; After operation finishes, utilize described electroscope and contact to fetch the conductor wire end of ground wire, reach and reduce operation intensity, minimizing activity duration, improve power supply reliability, improve the purpose of operating personnel's security.
The utility model is transformed the electrical verification contact, be arranged to the clamp shape, utilize the electrical verification contact to tangle ground wire conductor wire end through hole during operation and lay ground wire, the clamp through hole that operation finishes only to be needed to use the electrical verification contact to clamp conductor wire end can make ground wire leave setting, and the electrical verification contact plays the installation of ground wire conductor wire end and the appurtenance effect of dismounting.
Adopt telescopic insulating bar can stretch out enough length in use, carry out Job Operations; Shrink at ordinary times and get up also not influence storage; This structure also can be used for other connection that utilizes the utensil of insulating bar in addition, only needs connection device transformation is got final product.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
A kind of electroscopic device shown in Fig. 1,2 and 3 comprises electrical verification contact 1, electroscope 2, expansion link 3 and earthing device, and electrical verification contact 1 is fixed on the upper end of electroscope 2, and the lower end of electroscope 2 is threaded on the expansion link 3; Wherein electroscope 2 is arranged to two helicitic textures with the link of expansion link 3: internal thread and external thread, and internal thread is connected with the external thread of expansion link, and external thread is connected with the internal thread of expansion link end.Earthing device comprises ground wire 5 and the conductor wire end 4 that can be connected with setting, and conductor wire end 4 is made as the clamp shape, is provided with the auricle 41 of the movable connection of electrical verification contact in the clamp rear end, and auricle 41 is provided with through hole.
As shown in Figure 2, electrical verification contact 1 is arranged to the clamp shape, with electroscope 2 for rotating shaft is connected, and the width of electrical verification contact 1 is arranged to make things convenient for electrical verification contact 1 to clamp less than through hole width on the auricle 41; Can electrical verification contact 1 be rotated according to the position of auricle 41 simultaneously, conveniently be connected with auricle 41.Adopt electrical verification contact 1 directly to clamp setting, can carry out the electrical verification operation, after this operation and follow-up other operation finish, only need conductor wire end 41 is clamped setting, can carry out the ground connection operation; After all operations finishes, electrical verification contact 1 is clamped two auricles 41 of conductor wire end 41 clamps, make conductor wire end 41 clamps come off, thereby ground wire conductor wire end 41 is played the booster action of installing and removing.
Present relatively electroscope of the utility model product and ground wire because existing these two kinds of products are separately finished, need the proceed step by step operation when being correlated with operation in operation.This product is transformed telescopic electroscope, utilizes electroscope that the lead termination of ground wire is installed on the lead side, can significantly reduce the time of using when articulating ground wire, reduces the danger of operating personnel when outlet articulates ground wire.Operating efficiency and power supply reliability have been improved.
The utlity model has following advantage:
1, galvanoscopic termination can use cassette or screw-type to be connected on the telescopic insulating bar;
2, electroscope can use folder formula, cassette with being connected of ground wire conductor wire end termination, wear connections such as formula.
3, it is motionless that the operating personnel stands in the electrical verification position, carries out electrical verification operation earlier, electrical verification finish confirm that circuit does not have electricity after, more telescopic galvanoscopic electrical verification contact is withdrawn, collude and tangle earthing device conductor wire end through hole, ground wire is installed on the lead; The through hole of when fetching after the operation electrical verification contact being clamped earthing device conductor wire end clamp breaks away from electrical verification point and gets final product, and has improved work efficiency, power supply reliability greatly, and operating personnel's personal safety also can be guaranteed.
4, conventional method installs general 10～15 minutes time of needs from electrical verification to ground wire, also may be because reasons such as hanging method is improper, weather are incured loss through delay more time.As long as using method is correct, reasons such as weather are little to its influence, just can finish this work within 2～3 minutes behind use the utility model product.No matter be, still aspect standardized work, can both get best embodiment in power supply reliability.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
