Further, magnet is provided with in described first through hole.
Further, described insulating bar is provided with the third through-hole axially arranged.
The beneficial effects of the utility model:
Action bars head of the present utility model is provided with insulating bar, and action bars head is fixed on action bars by insulating bar.For avoiding action bars head to be separated with crane, action bars head of the present utility model also comprises arc convex and latch assembly, and wherein, latch assembly comprises holder, check lock lever and elastic component, holder and arc convex hinged, its formation axle center, hinged place.After check lock lever catches on crane, elastic component orders about check lock lever and rotates around axle center, and after check lock lever is rotatably inserted into the first through hole, crane will be fastened on action bars head.
Accompanying drawing explanation
Fig. 1 is the structural representation of action bars head in the utility model;
Fig. 2 is the structural representation (after amplifying) that in the utility model, action bars head is positioned at latch assembly place.
Embodiment
With reference to Fig. 1, a kind of action bars head, comprises insulating bar 1, arc convex 2 and latch assembly, and insulating bar 1 and latch assembly are separately fixed at all sides of arc convex 2, and insulating bar 1 is for attended operation bar, and latch assembly is for winning the crane of reversal of the natural order of things on high-tension bus-bar.
See figures.1.and.2, latch assembly comprises holder 3, check lock lever 4 and elastic component 5.Action bars head also comprises connecting rod 6, and connecting rod 6 is simultaneously through holder 3 and arc convex 2, hinged with arc convex 2 to realize holder 3, and the central shaft of connecting rod 6 is the axle center of holder 3 and arc convex 2 hinged place.Holder 3 is provided with the second through hole 31 coordinated with check lock lever 4, check lock lever 4 can move axially along the second through hole 31.Conflict on the sidewall of arc convex 2 in elastic component 5 one end, elastic component 5 other end is conflicted on check lock lever 4, and elastic component 5 can promote check lock lever 4 under compression, and check lock lever 4 is subject to thrust and holder 3 can be driven to rotate around connecting rod 6.
See figures.1.and.2, the centre position of arc convex 2 is provided with the first through hole 21, check lock lever 4 is after connecting rod 6 rotates, the end of check lock lever 4 can insert in the first through hole 21, the sidewall of arc convex 2 is provided with the locking slot 22 axially arranged, the top of check lock lever 4 can be inserted in locking slot 22, rotates to avoid check lock lever 4.
See figures.1.and.2, the operation principle of the present embodiment: first, is arranged on action bars by insulating bar 1; Then, continuous move operation bar, so that check lock lever 4 catches on crane; Finally, after check lock lever 4 catches on crane, pulling operation bar makes the top of check lock lever 4 exit in locking slot 22, under the state that check lock lever 4 is separated with locking slot 22, check lock lever 4 rotates around connecting rod 6, and the end of check lock lever 4 is inserted in the first through hole 21, thus realizes check lock lever 4 and fix crane.
With reference to Fig. 2, insert in the first through hole 21 for realizing check lock lever 4, the end of check lock lever 4 is provided with the first bending section 41, and check lock lever 4 is inserted in the first through hole 21 by the first bending section 41.
With reference to Fig. 2, crane is caught on for realizing check lock lever 4, the second bending section 42 is provided with by subterminal position at check lock lever 4, check lock lever 4 defines a draw-in groove 43 at the second bending section 42 place, after crane inserts draw-in groove 43, cable maintenance workman pulling operation bar, moves up to be separated with locking slot 22 to realize check lock lever 4.For increasing the bonding strength of check lock lever 4 and locking slot 22, in the present embodiment, tapered rod made by check lock lever 4, concrete, the diameter of check lock lever 4 near second bending section 42 one end is less than the diameter of check lock lever 4 near locking slot 22 one end, and this structure can realize check lock lever 4 and locking slot 22 interference fit.
In the present embodiment, check lock lever is tapered rod, except can increasing the bonding strength of check lock lever and locking slot, the most important effect of tapered rod to limit the distance of check lock lever along the second through hole movement, to avoid check lock lever displacement excessive, thus the first bending section of check lock lever cannot be inserted in the first through hole.
For avoiding check lock lever displacement excessive and causing the first bending section cannot insert in the first through hole, in the present embodiment, the diameter of the first through hole is far longer than the width of the first bending section, and this structure achieves coordinating of the first bending section and the first through hole.But this structure also brings hidden danger, after the first bending section inserts the first through hole, check lock lever and elastic component are in the state be separated, and this just means, arc convex is towards generation reversion or tilt, and the first bending section is easy to just exit in the first through hole.For head it off, in the present embodiment, be provided with magnet (certainly, corresponding first bending section is ironwork) in the first through hole, to avoid the first bending section after arc convex generation radial rotary, exit in the first through hole.
With reference to Fig. 1, being connected with action bars for realizing insulating bar 1, being axially provided with at insulating bar 1 third through-hole 11 coordinated with action bars.
The above, be only embodiment of the present utility model, but protection range of the present utility model is not limited thereto, and those of ordinary skill in the art should be understood that the content that the utility model includes but not limited to accompanying drawing and describes in embodiment above.Any amendment not departing from function and structure principle of the present utility model all will comprise within the scope of the appended claims.
