Detailed description of the invention

Describe the present invention with specific embodiment below in conjunction with the accompanying drawings:

It is a specific embodiment of the present invention as shown in figs. 1-7, including the wire clip body 1 with wedged hole, with metallic channel Voussoir, described voussoir is made up of with right voussoir 2-2 left voussoir 2-1, arranges locating slot 12 respectively on the voussoir faying face of left and right With the plate 13 inserted in locating slot, forming metallic channel 3 after left and right voussoir is involutory, in wire clip body 1 cavity, both sides turns Axle 4, installs the gear 5 being sleeved in rotating shaft 4 in cavity, and it is empty from wire clip body 1 that rotating shaft 4 is set to hexagonal rotating shaft and its one end Intracavity stretches out, and is respectively provided with the tooth bar 7 that can engage with gear 5 in the bottom of left and right voussoir, left and right voussoir and wire clip body 1 it Between guiding parts is set.

As in Figure 3-5, respective plate 13, when involutory installation, is inserted directly into the locating slot 12 of correspondence by two voussoirs Can realize the involutory installation between two voussoirs, the tooth bar 7 bottom the voussoir of left and right also can be mutually aligned simultaneously, and plate 13 is with fixed Position groove 12 allows the easier for installation of left and right voussoir and accurate positioning；

After the alignment of left and right voussoir, wire 10 is inserted in metallic channel 3, as shown in Figure 1-2, first with hands by the front end of voussoir toward wedge Carry out pushing away in shape hole putting, at voussoir from the big opening end of wedged hole toward during osculum end motion, voussoir outer wall and wedged hole inwall Between frictional force become larger and tooth bar 7 gradually contacts with gear 5 and engages each other, carry out pushing away putting now by hands It is difficult to allow voussoir move toward the osculum extreme direction of wedged hole again, is therefore rotated the outer end of hexagonal rotating shaft, hexagonal by speeder wrench Rotating shaft driven gear 5 rotates, and the gear 5 of rotation transmits the force to tooth bar 7 intermeshing with it, and final tooth bar 7 drives voussoir Osculum extreme direction toward wedged hole continues to move to, and rotates rotating nut 6 continuously eventually through spanner by whole voussoir and wire 10 Fully-inserted wedged hole is interior and completes the clamping guiding 10.

Especially for work high above the ground, for the strain clamp without these rack pinion parts, people's electricity to be stood in The top of line bar, taps voussoir continuously by rubber hammer or wooden mallet, percussion process percussion to be waved instrument, and movement range is big, and ten thousand One percussion is inaccurate, and staff is easy to shake and has danger of falling；Continuous print taps voussoir simultaneously, and voussoir end can be allowed to hold It is easily generated deformation, taps process firmly inequality simultaneously and cause unbalance stress between voussoir outer wall and wedged hole inwall, therefore voussoir Whole being more prone to deforms, and the voussoir after deformation is in use easier to aging, greatly reduces its service life； The present inventor carries out rotating shaft by spanner, then is driven the osculum end of whole voussoir often wedged hole by rack pinion Direction is moved, and the amplitude of wrench operated action is little, and people is not easy to produce at electric pole top and acutely rocks, and substantially increases its behaviour Make safety coefficient；Spanner behaviour firmly ratio is milder simultaneously, and gear is gradually band carry-over bar and rack drives wedge block movement, unlike Between percussion process such voussoir outer wall and wedged hole inwall stress sudden change, therefore voussoir with in wedged hole inwall extrusion process Deform little, it is not easy to occur aging, substantially prolongs its service life.

In this example, described guiding parts includes the guide plate 8 being separately positioned on voussoir top, left and right, along wire clamp originally The length direction of body 1 also offers longitudinally guiding mouth 9 on the top of wedged hole, is combined in two guide plates 8 of a piece along longitudinally leading Seesaw to mouth 9.In the engagement process of rack-and-pinion and in voussoir and wedged hole inwall extrusion process, voussoir meeting sometimes Producing skew, just engagement is inaccurate and mutually produces skew for such wheel and rack, owing to devising this guiding parts, and guide plate 8 Alignment guide mouth 9 also seesaws along targeting port 9 all the time, thus effectively prevent offsetting from each other of wheel and rack, protects Demonstrate,prove effective enforcement of conductor clamping process.Simultaneously during subsequent use, between wheel and rack, remain engagement State, further increases the resistance to voussoir, and voussoir is less likely to occur to loosen, and therefore wire can be clamped for a long time, improves The use function of this kind of strain clamp.

In this example, bottom wire clip body 1, connection through hole 11 is offered at two ends respectively, by through hole 11 by this resistance to bracing cable Clamping fixed the most on utility poles.
