Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
The structure of the strain clamp of the present embodiment is as follows:
Understood incorporated by reference to Fig. 1, the strain clamp of the present embodiment includes: a wire clip body 1 and a drag hook 3, understood incorporated by reference to Fig. 2, this wire clip body 1 is provided with wedge cavities 6 and a drag hook groove 7, the two side of this drag hook groove 7 is arranged with multipair connecting hole 8 along wedge shape direction, understood incorporated by reference to Fig. 5, two ends of this drag hook 3 are hook-shaped 14, two ends of this drag hook 3 can be inserted this drag hook groove 7 and are snapped in a pair connecting hole in this multipair connecting hole 8, a wedge shape sandwich 2 is only provided with in each wedge cavities 6, the two sides of this wedge shape sandwich 2 have a pair C shape wire casing 10 respectively along wedge length direction, understood incorporated by reference to Fig. 4, namely this wedge shape sandwich 2 is arranged altogether four C shape wire casings 10, those C shape wire casings 10 can form clamp groove 12 with the wedge cavities wall 5 of this wedge cavities 6, the sectional area of this clamp groove 12 reduces gradually when this wedge shape sandwich 2 inserts this wedge cavities 6, so that clamping cables.
Understood incorporated by reference to Fig. 3, the internal face of this C shape wire casing 10 is evenly distributed with wavy puncture tooth 9, the cross section of those puncture teeth 9 is saw tooth wave shape.Go into battle and show multiple through hole 16 in the bottom surface of this wedge shape sandwich 2, the material of this wedge shape sandwich 2 is polypropylene (Polypropylene is called for short PP).Through hole 16 can not only save the use of polypropylene material, and can reduce the weight of wedge shape sandwich 2 and increase the toughness of puncture tooth 9, and through hole 16, by distortion, can cushion cable to puncture tooth 9 extruding force with avoid puncture tooth 9 to suffer rigid destruction.
Please continue composition graphs 3 to be understood, the end of this wedge shape sandwich 2 is connected with a connecting band 11, and the end of this connecting band is provided with a C shape snap ring 17, and this C shape snap ring 17 is for being snapped in the stem of this drag hook 3.
Understood incorporated by reference to Fig. 6, the side of this drag hook groove 7 is provided with an anti-flake 4 of drag hook, the two ends of the anti-flake 4 of this drag hook are provided with buckle slot 15, this buckle slot 15 includes a peristome successively, a bending transition part and a C shape limiting section, two stems of this drag hook slip over this peristome and this bending transition part when mounted successively, and are bound by this C shape limiting section.
The operation principle of the strain clamp of the present embodiment is as follows:
During installation, understood incorporated by reference to Fig. 1-4, this drag hook 3 is hooked on electric pole, promote this wedge shape sandwich 2, two core bundling insulated cables or four-core centralized insulated cable are put into wedge cavities 6 from the opening 13 of wire clip body 1, then insert in the C shape wire casing 10 of wedge shape sandwich 2, and strain cable, insulated cable can be made to open tighter and tighter under the effect of insulated cable deadweight and wedge-like engagement tensile force.
Adjustment drag hook 3, relative to the link position of connecting hole 8, can regulate the mounting distance between strain clamp and electric pole.
The technique effect of the strain clamp of the present embodiment is as follows:
The first, by using the wedge shape sandwich with C shape wire casing, this strain clamp has to be assembled easily, without the high advantage of Relative sliding, both sides extruding uniform force and reliability.
The second, by being evenly distributed with wavy puncture tooth on the internal face of this C shape wire casing, add the grip to insulated cable, fully can prevent cable under the effect of strong pulling force from clamp groove 12 slippage or deviate from.
Three, those connecting holes 8 can make drag hook 3 move along wedge shape bearing of trend, facilitate the mounting distance regulated between strain clamp and electric pole.
Four, the end of wedge shape sandwich is connected with the connecting band with C shape snap ring, and C shape snap ring can be facilitated to be snapped on the stem of drag hook, prevents wedge shape sandwich 2 landing from the wedge cavities 6 of wire clip body 1 in work progress.
Five, the two ends of the anti-flake 4 of drag hook are provided with buckle slot 15, and during installation, two stem bayonet sockets of drag hook 3 are in those buckle slots 15, and prevent drag hook 3 under external force, strain comes off from connecting hole 8, affects power construction safety.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection range of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these execution modes, but these change and amendment all falls into protection range of the present utility model.
