Abstract

The utility model relates to a free telescopic electroscope, comprising: an electroscope head 1, a plastic sleeve 2, a top spring 3, a plastic buckle 4, a connecting wire 5, an inner interface nut 6, an inner connecting surface 7, an inner interface wire 8, an internal gear 9, an external gear 10, a signal phonation button 11, a rubber sleeve 12, a safety handle 13, a telescopic tube 14, and an outer connecting surface. The electroscope is characterized in that; the telescopic tube 14 is made of insulation epoxy glass fiber reinforced plastics materials, when one head internal gear 9 of the telescopic tube 14 is inserted into the tail of another external gear 10, the telescopic tube will not be pulled out entirely but is just right, a rubber sleeve 12 is designed on the safety handle 13 by the inventor, which is used to represent the safe area in operating. The inner connecting surface 7 is the inserted inner surface of the outer connecting surface 15, the outer connecting surface 15 is a connecting surface which can be inserted into the inner connecting surface 7 and can effectively inosculate the inserted connection.

Description

The telescopic electroscope of a kind of freedom

Technical field

The utility model relates to a kind of high voltage electroscope, the telescopic electroscope of particularly a kind of freedom.

Background technology

In the work progress of high-tension electricity conveying circuit, for the sake of security, at first cut off the electricity of this working line, have or not electricity with the electroscope check then, confirm not have electricity back further work.Existing known high voltage electroscope because volume is big, carries inconvenience, also requires further improvement.

Summary of the invention

The purpose of this utility model is to provide a kind of improvements over the prior art.The utility model is achieved in that the telescopic electroscope of a kind of freedom, by electrical verification head, plastic jacket, top spring, plastics hitch, connect silk, inner joint mother, in connect face, inner joint silk, home record, overside, signal sounding button, rubber sleeve, safety handle, draw-tube, external and form, described draw-tube is a kind ofly to make with the insulating epoxy glass-reinforced plastic material, and insulation effect is very desirable.The method for making of described draw-tube: be that the expoxy glass steel tubing that does not wait from coarse to fine is cut into required tubing section, connect glue and be stained with and connect one 5 centimeters wide, 0.3 centimeter thick plastic skin with being stained with at one every section of the tubing section.Also be stained with in the inside of every section other end and connect 0.3 centimeter thick plastic skin, when draw-tube stem home record injects another section overside afterbody like this, can not cause and all be pulled out, just right, can make one meter to eight meters draw-tube according to the needs of operation like this, upper end at the safety handle has one external, external connects 3 centimeters of face the insides in can inserting, effectively connect, form a kind of free connector that matches, the safety zone when safety has designed that a rubber sleeve is used for representing to operate to top inventor.Design has the inner joint silk below galvanoscopic, and the inner joint silk is screwed on the inner joint mother, connects silk and is screwed in plastic jacket and buckles.

Of the present utility model succeeding in developing given the workmen of high-tension electricity conveying circuit the condition that brings great convenience, and has the back of contraction volume little, easy to carry, and the effect that electrical verification is safer is convenient to apply in the power industry construction.

Description of drawings

Fig. 1 is a contraction of the present utility model back structural representation

Fig. 2 is a main exploded view of the present utility model

Fig. 3 is a cut-away section synoptic diagram of the present utility model

Among the figure: 1 electrical verification head, 2 plastic jackets, 3 top springs, 4 plastics hitch, 5 connect silk, connect face in the 6 inner joint mothers, 7,8 inner joint silks, 9 home records, 10 oversides, 11 signal sounding buttons, 12 rubber sleeves, 13 safety handles, 14 draw-tubes, 15 external

Embodiment

As shown in the figure; electrical verification 1 is operating personnel contact circuit when electrical verification a contact point; plastic jacket 2 is plastic casings that fixedly electrical verification 1 and protection electroscope are used; top spring 3 is the effective tools that connect electrical verification 1; plastics hitch 4 is the connection mothers that connect silk 5; connecing silk 5 is the connecting filaments that connect plastics hitch 4 at electroscope on one's body; inner joint mother 6 is connected usefulness with inner joint silk 8; in connect face 7 by external 15 inner face of pegging graft; inner joint silk 8 is the connecting filaments that are screwed in inner joint mother 6; home record 9 is to prevent that expansion link overside 10 from pulling out and effectively coincide fastening means; overside 10 is and expansion link home record 9 effectively identical fastening means; signal sounding button 11 is to check before electrical verification work; the self-checking unit whether electroscope can operate as normal be used; safety zone when rubber sleeve 12 is used for representing to operate; hand when safety is electrical verification work to 13 is taken the position; draw-tube 14 is a kind ofly to make can stretch the same with fishing rod with the insulating epoxy glass-reinforced plastic material and can contract; shrink the portable utensil in back, external 15 is to connect face 7 in inserting can effectively coincide and insert the joint face of connection.
