Summary of the invention
Technical assignment of the present invention is to above-mentioned deficiency of the prior art a kind of spring PT insurance to be provided; This spring PT insurance has protective tube and changes dismounting easily, has improved operating efficiency, when protective tube damages; The protective tube that only need more renew gets final product, and has reduced the characteristics of cost.
The technical solution adopted for the present invention to solve the technical problems is: it comprises the high-tension fuse body and is arranged on the intrinsic protective tube of high-tension fuse; The both sides of described high-tension fuse body are respectively arranged with left outer cover and right outer cover; The bottom of described left outer cover and right outer cover is respectively arranged with terminal block; Described left outer cover and right outer cover fix through the both sides of cap nut and screw and high-tension fuse body respectively, and described cap nut is separately positioned on the outer surface of left outer cover and right outer cover, and described left outer cover is an enclosed construction; The right openings of described right outer cover; Opening part is provided with outer stifled, and the described outer stifled clamping apparatus that passes through links to each other with right outer cover, is provided with spring between the left side of described protective tube and the left outer cover.
Described clamping apparatus comprises connecting plate, clamp, contiguous block, fixed mount, steady pin, connecting pin and clamp; The middle part of described clamp is with outer stifled fixing; One end and the connecting plate of clamp are movably connected, and the outer surface of the other end is provided with draw-in groove, and an end of described connecting plate and right outer cover is fixed; The other end of right outer cover is fixed with contiguous block; Described fixed mount and contiguous block flexibly connect through connecting pin, are respectively arranged with fixing hole on described fixed mount and the contiguous block, and described fixed mount and contiguous block insert in the fixing hole through steady pin and fix; Described fixed mount is provided with clamp, snaps in the draw-in groove through clamp between described fixed mount and the clamp to fix.
Be provided with connecting line between described connecting plate and outer the blocking up.
Described fixed mount, clamp and steady pin are respectively stainless steel.
Spring PT insurance of the present invention is compared with prior art, and have following outstanding beneficial effect: outer cover is provided with an opening, and opening part is provided with outer stifled through clamping apparatus; When changing the dismounting protective tube, outer the blocking up on the outer cover opened easily, and protective tube is changed and removed easily; Reduced labour intensity, improved operating efficiency, when protective tube damages; Characteristics such as the protective tube that only need more renew gets final product, and has reduced cost, and is easy to use.

Embodiment
Explanation at length below 4 pairs of spring PT insurances of the present invention are done with reference to Figure of description 1 to accompanying drawing.
Spring PT insurance of the present invention; Its structure comprises high-tension fuse body 4 and the protective tube 3 that is arranged in the high-tension fuse body 4; The both sides of described high-tension fuse body 4 are respectively arranged with left outer cover 1 and right outer cover 6, and the bottom of described left outer cover 1 and right outer cover 6 is respectively arranged with terminal block 15, and described left outer cover 1 fixes through cap nut 14 and the both sides of screw 13 with high-tension fuse body 4 respectively with right outer cover 6; Described cap nut 14 is separately positioned on the outer surface of left outer cover 1 and right outer cover 6; Described left outer cover 1 is an enclosed construction, the right openings of described right outer cover 6, and opening part is provided with outer stifled 7; Described outer stifled 7 pass through clamping apparatus links to each other with right outer cover 6, is provided with spring 2 between the left side of described protective tube 3 and the left outer cover 1.
Described clamping apparatus comprises connecting plate 8, clamp 10, contiguous block 11, fixed mount 5, steady pin 16, connecting pin 9 and clamp 12; The middle part of described clamp 10 is fixing with outer stifled 7; One end and the connecting plate 8 of clamp 10 are movably connected, and the outer surface of the other end is provided with draw-in groove 19, and described connecting plate 8 is fixed with an end of right outer cover 6; The other end of right outer cover 6 is fixed with contiguous block 11; Described fixed mount 5 flexibly connects through connecting pin 9 with contiguous block 11, is respectively arranged with fixing hole 17 on described fixed mount 5 and the contiguous block 11, and described fixed mount 5 inserts in the fixing hole 17 through steady pin 16 with contiguous block 11 and fixes; Described fixed mount 5 is provided with clamp 12, snaps in the draw-in groove 19 through clamp 12 between described fixed mount 5 and the clamp 10 to fix.
Be provided with connecting line 18 between the described connecting plate 8 and outer stifled 7.Make connection more firm.
