Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the present invention includes metal wire clamp, major insulation action bars and the boost bar being sequentially connected with;Described major insulation action bars includes that hollow insulating sleeve 1 and self-locking rotate bar 2, hollow insulating sleeve 1 and self-locking rotate bar 2 all in hollow columnar structures, hollow insulating sleeve 1 is located at self-locking by bearing turning set and rotates on bar 2, and self-locking rotates bar 2 two ends and outwards each extends over out extension and lower extension.Self-locking rotates the upper extension of bar 2 upper end and uses six prism structures, and self-locking rotates and is respectively provided with a spacing hole in two opposing sidewalls of extension on bar 2 top, and scalable fixture block 3 is located in spacing hole, and fixture block 3 front end stretch out spacing hole;Self-locking rotates the lower extension of bar 2 lower end and uses six prism structures, and two relative inner walls of the lower extension that self-locking rotates bar 2 lower end are respectively provided with a hole clipping 5.Described metal wire folder includes U-shaped hook 6, the hinged connecting rod 8 of bolt 7 is passed through in one end of U-shaped hook 6, connecting rod 8 is provided with screwed hole 9, screwed hole 9 female thread connects 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 that the lower end of screw rod 11 rotates bar 2 with self-locking is fixed;Described boost bar includes hand-rail type insulated handle 12, hand-rail type insulated handle 12 is connected with major insulation action bars by self-locking external member 21, the upper extension structure that self-locking external member 21 structure rotates bar 2 top with self-locking is identical, and self-locking external member 21 rotates bar 2 lower extension with self-locking and mates grafting, the fixture block 3 of self-locking external member 21 embeds in the hole clipping 5 that major insulation action bars self-locking rotates bar 2 lower end lower extension.
The present invention is in order to meet the use requirement of different electric pressure, also include a supplementary insulation action bars, removably connect with the lower end of major insulation action bars, supplementary insulation action bars is with the difference of major insulation action bars: the hollow insulating sleeve 13 of supplementary insulation action bars is internal is provided with bidirectional ratchet group 19, and on the hollow insulating sleeve 13 of supplementary insulation action bars, it is provided with button hole 17, bidirectional ratchet change-over switch 18 is arranged in button hole 17, and fixture block 15 coupling that supplementary insulation action bars self-locking rotates on top six prism structure of bar 14 is located in the hole clipping 5 of six prism structures that major insulation action bars self-locking rotates bar 2 lower end;Now, then by the fixture block of the self-locking external member 21 of boost bar it is stuck in the hole clipping 16 of the lower end that supplementary insulation action bars self-locking rotates bar 14.
After U-shaped hook 6 and the briquetting 10 of the metal wire clamp of the present invention combines, presenting enclosed arc jaws, be used for clamping wire, arc jaws makes wire tightr with the laminating of metal wire clamp.When carrying out practical operation, staff holds hollow insulating sleeve 1 and remains stationary as, another holds the boost bar of hollow insulating sleeve 1 afterbody installation and rotates, the direction rotated is according to the direction setting of screw thread, the jaws of metal wire clamp is opened, during rotating, the bearing 20 respectively arranged by upper and lower two ends with self-locking rotation bar 2 due to hollow insulating sleeve 1 is connected, largely, reduce the force dynamics of user, and making self-locking rotate bar 2 drives the briquetting 10 of screw rod 11 and screw tip to move downwardly together, now, the jaws of metal wire clamp can be opened, after opening jaws, hanging of high aloft electric wire can be carried out.After hanging, same mode of operation can be used, rotate in the opposite direction, thus the briquetting 10 of screw rod 11 and screw tip is moved upwardly together, wire is fixed on inside arc jaws.
In order to meet the use requirement of different electric pressure, the present invention uses stagewise insulating bar, not only include a major insulation action bars, also include a supplementary insulation action bars, single hop or two sections of insulating bars can be used according to the different of onsite application height, simultaneously so that be attached and removed from convenient, we use self-locking to rotate the structure of bar, only the self-locking rotation bar of stagewise insulating bar need to be forcibly inserted into or be extracted and just can install or remove two sections of insulating bars during use.As a example by major insulation action bars, owing to self-locking rotates, bar 2 devises self-locking mechanism (self-locking mechanism is exactly fixture block and hole clipping 5 structure) so that stagewise insulating bar is the most firm after connecting.Described self-locking rotates the upper extension of bar 2 upper end and uses six prism structures, self-locking rotates the lower end lower extension of bar 2 and uses six prism structures, self-locking rotates and is respectively provided with a spacing hole in two opposing sidewalls of six prism structures of extension on the upper end of bar 2, scalable fixture block 3 it is provided with in spacing hole, scalable fixture block 3 mainly utilizes a spring 4, one scalable fixture block 3 is respectively set at the two ends of spring 4, just as the opening device of the umbrella of our every day use;Self-locking rotates the lower end lower extension of bar 2 and uses six prism structures, and two relative inner walls of the lower extension of six prism structures are respectively equipped with a hole clipping 5;On the one hand six prism structures conveniently pull and push, and are on the other hand mainly used in using hand-rail type insulated handle 12 to rotate when, it is possible to preferably rotate.When being attached or dismantle, the lower extension of supplementary insulation action bars self-locking is rotated bar 14 upper end upper extension and major insulation action bars lower end plugs, when carrying out grafting, supplementary insulation action bars self-locking rotates two fixture blocks 15 of the upper extension of bar 14 upper end can be the most flexible, when being plugged into certain degree when stress, during the hole clipping 5 of the lower end that fixture block 15 runs into major 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 major insulation action bars or supplementary insulation action bars, use the same connected mode.When needs use supplementary insulation action bars, bidirectional ratchet group 19 structure can also be utilized, bidirectional ratchet group 19 structure can be by the way of switching bidirectional ratchet change-over switch 18, carry out the switching of direction of rotation, insulating bar can only be rotated to a direction, on the one hand can use when carrying out stepping up wire, once would not loosen after clamping wire, fundamentally avoid the problem that earth lead surprisingly comes off;On the other hand, when needs disassemble from wire, it is switched to contrary direction, so be more prone to so that staff quickly dismantles.Bidirectional ratchet group 19 structure belongs to existing mature technology, and the most how in this not go into detail utilizes.Meanwhile, the present invention also uses boost bar, increases the moment to insulating bar by lever principle so that the grip force of wire, when applying less active force, just can be greatly increased, thus save manpower by staff by earthing wire clip.
