Embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the present invention includes metal wire clamp, main insulation action bars and the boost bar connecting successively; Described main insulation action bars comprises hollow insulating sleeve 1 and self-locking dwang 2, hollow insulating sleeve 1 and self-locking dwang 2 are all hollow columnar structures, hollow insulating sleeve 1 is rotated and is set on self-locking dwang 2 by bearing, and upper extension and lower extension are outwards extended respectively in self-locking dwang 2 two ends.The upper extension of self-locking dwang 2 upper ends adopts six prism structures, on self-locking dwang 2 tops, in two opposing sidewalls of extension, is respectively provided with a spacing hole, and scalable fixture block 3 is located in spacing hole, and fixture block 3 front end stretch out spacing hole; The lower extension of self-locking dwang 2 lower ends adopts six prism structures, on two relative inner walls of the lower extension of self-locking dwang 2 lower ends, is respectively provided with a hole clipping 5.Described metal wire folder comprises U-shaped hook 6, one end of U-shaped hook 6 is by the hinged connecting rod 8 of bolt 7, connecting rod 8 is provided with screwed hole 9, screwed hole 9 internal threads are connected with screw rod 11, the upper end of screw rod 11 is fixed with a briquetting 10, the downward curved depression of upper surface of briquetting 10, the top of the lower end of screw rod 11 and self-locking dwang 2 is fixed; Described boost bar comprises hand-rail type insulated handle 12, hand-rail type insulated handle 12 is connected with main insulation action bars by self-locking external member 21, self-locking external member 21 structures are identical with the upper extension structure on self-locking dwang 2 tops, and self-locking external member 21 is mated grafting with self-locking dwang 2 lower extension, the fixture block 3 of self-locking external member 21 embeds in the hole clipping 5 of main insulation action bars self-locking dwang 2 lower end lower extension.
The present invention is in order to meet the instructions for use of different electric pressures, also comprise a supplementary insulation action bars, removably connect with the lower end of main insulation action bars, the difference of supplementary insulation action bars and main insulation action bars is: hollow insulating sleeve 13 inside of supplementary insulation action bars are provided with bidirectional ratchet group 19, and be provided with button hole 17 on the hollow insulating sleeve 13 of supplementary insulation action bars, bidirectional ratchet change-over switch 18 is arranged in button hole 17, and the fixture block on top six prism structures of supplementary insulation action bars self-locking dwang 14 15 mates in the hole clipping 5 of six prism structures that are located in main insulation action bars self-locking dwang 2 lower ends, now, then the fixture block of the self-locking external member 21 of boost bar is stuck in the hole clipping 16 of lower end of supplementary insulation action bars self-locking dwang 14.
After U-shaped hook 6 and the briquetting 10 of metal wire clamp of the present invention combines, present enclosed arc jaws, for clamping wire, arc jaws makes wire and metal wire clamp fit tightr.When carrying out practical operation, staff holds hollow insulating sleeve 1 and keeps motionless, the boost bar that another holds hollow insulating sleeve 1 afterbody installation is rotated, the direction of rotation is according to the direction setting of screw thread, the jaws of metal wire clamp is opened, in the process of rotation, because hollow insulating sleeve 1 is connected by each bearing 20 arranging of upper and lower two ends with self-locking dwang 2, to a great extent, reduced user's application of force dynamics, and make self-locking dwang 2 drive the briquetting 10 at screw rod 11 and screw rod top to move downward together, now, can open the jaws of metal wire clamp, open after jaws, can carry out hanging of high aloft electric wire.After hanging, can adopt same mode of operation, be rotated in the opposite direction, thereby the briquetting 10 at screw rod 11 and screw rod top is moved upward together, wire is fixed on to arc jaws inner.
In order to meet the instructions for use of different electric pressures, the present invention adopts segmented insulating bar, not only comprise a main insulation action bars, also comprise a supplementary insulation action bars, can use the difference of height to use single hop or two sections of insulating bars according to scene, in order to make, to connect and remove convenient simultaneously, we adopt the structure of self-locking dwang, only the self-locking dwang of segmented insulating bar just firmly need be inserted or extract and can install or remove two sections of insulating bars during use.Take main insulation action bars as example, owing to having designed self-locking mechanism (self-locking mechanism is exactly fixture block and hole clipping 5 structures) in self-locking dwang 2, very firm after segmented insulating bar is connected.The upper extension of described self-locking dwang 2 upper ends adopts six prism structures, the lower end lower extension of self-locking dwang 2 adopts six prism structures, on the upper end of self-locking dwang 2, in two opposing sidewalls of six prism structures of extension, a spacing hole is set respectively, in spacing hole, be provided with scalable fixture block 3, scalable fixture block 3 mainly utilizes a spring 4, a scalable fixture block 3 is respectively set, just as the opening device of the umbrella of our every day use at the two ends of spring 4; The lower end lower extension of self-locking dwang 2 adopts six prism structures, on two relative inner walls of the lower extension of six prism structures, is respectively equipped with a hole clipping 5; Six prism structures conveniently pull and push on the one hand, are mainly used on the other hand, when using hand-rail type insulated handle 12 to be rotated, can better rotating.When connecting or dismantle, the lower extension of the upper extension of supplementary insulation action bars self-locking dwang 14 upper ends and main insulation action bars lower end is plugged, when pegging graft, two fixture blocks 15 of the upper extension of supplementary insulation action bars self-locking dwang 14 upper ends can, under stressed state, inwardly stretch, when being plugged into certain degree automatically, when fixture block 15 runs into the hole clipping 5 of lower end of main insulation action bars, can eject automatically, be stuck in hole clipping 5, complete auto-lock function; Same, when boost bar is connected with the lower end of main insulation action bars or supplementary insulation action bars, adopt the same connected mode.When needs use supplementary insulation action bars, can also utilize bidirectional ratchet group 19 structures, bidirectional ratchet group 19 structures can be by switching the mode of bidirectional ratchet change-over switch 18, be rotated the switching of direction, insulating bar can only be rotated to a direction, can when stepping up wire, use on the one hand, once just can not become flexible after clamping wire, fundamentally avoid the problem of earth connection accidental; On the other hand, at needs, when wire disassembles, be switched to contrary direction, be more prone to like this make staff to dismantle fast.Bidirectional ratchet group 19 structures belong to existing mature technology, and how in this not go into detail utilizes in the present invention.Meanwhile, the present invention also uses boost bar, by lever principle, increases the moment to insulating bar, makes staff when applying less active force, just earthing wire clip can be increased greatly to the folder power of wire, thereby save manpower.
