Strain clamp, be mainly used in fixing cord, to bear wire tension, and wire is hung in strain insulator-string group or shaft tower, the existing strain clamp for bunched cable, mostly be that the strain clamp used from traditional bare wire improves, weak point is that grip is less, construction inconvenience, therefore, application number be 201120439851.8 utility model provide a kind of four-core strain clamp, mainly comprise wedge shape arm-tie, the two sides up and down of wedge shape arm-tie are provided with wire-clamping device, wire-clamping device comprises base and covers the upper cover be located at above base, by arranging elastic component between base and upper cover, upper cover and base can be strutted, be convenient to cable pass, and due to the existence of elastic component, also can play the advantage preventing bolt fastening component from loosening.
But this four-core strain clamp, the side of the projection contacted with upper cover due to base is in vertically arranging, but like this when installation, upper cover is wanted on inserted base just very inconvenient, upper cover inside is inserted because protruding when installing, protruding needs abuts against with upper cover, ensure the stability of upper cover, the width of such projection needs equal to the width above covering corresponding groove, protruding being difficult to when inserting upper cover is so just easily caused to be aimed at, assembling is inconvenient, and, after projection is extruded by electric wire, because projection is that rubber is made, after projection is extruded, protruding both sides can outwards be opened, protruding width is caused to increase, because rubber has certain Memorability, therefore after projection is opened outward, want projection to insert in upper cover and be just more not easy.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of four-core centralized strain clamp that can be conveniently installed to by upper cover on base.
For achieving the above object, the utility model provides following technical scheme: a kind of four-core centralized strain clamp, comprise wedge shape arm-tie, the both sides up and down of described wedge shape arm-tie are provided with the clamping device for clamping cable, described clamping device comprises base and is located at the upper cover above base, described clamping device also comprises the secure component driving base and upper cover to fasten, clamping part is provided with between described base and upper cover, described clamping part comprises the projection be fixedly installed on base and the groove being arranged on the protruding insertion of the confession covered, the cross section of described projection is up-small and down-big trapezoidal setting, described protruding bottom abuts with the sidewall of groove.
Preferably, block is settled in the outwardly formation in described wedge shape arm-tie both sides, and be equipped with the pull bar of U-shaped setting in described arrangement block, the partial threads that described pull bar passes installing hole is connected with the stop nut come off in installing hole for limiting pull bar.
Preferably, the quantity of described stop nut is two.
Preferably, described secure component comprises successively through bolt and the clamp nut of upper cover, base and wedge shape arm-tie.
Preferably, the quantity of bolt is two, is separately positioned on the two ends of wedge shape arm-tie.
By adopting technique scheme, to be arranged to two of projection sides to tilt, like this when projection being inserted in groove, the width due to convex top is the width being less than groove, such projection can be inserted in groove very easily, further, in use, even if after projection is squeezed, cross section due to projection is trapezoidal setting, projection can bear larger pressure, and protruding deflection will be very little, can not affect follow-up assembling.
