Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

3. As shown in fig. 1-4, the utility model provides an electric grounding wire fixing clamp, which comprises a clamp bracket 3 for connecting a cable body 1 and a cable grounding wire 2;

the equal fixedly connected with card strap 31 in upper and lower surface of clamp support 3 one end, and clamp support 3 keeps away from the equal fixedly connected with guiding hole 32 in upper and lower surface of card strap 31 one end, ratchet storehouse 33 has been seted up to clamp support 3's inside, ratchet storehouse 33 internal rotation is connected with ratchet 34, ratchet storehouse 33's inner wall articulates there is pawl 35, ratchet 34's both ends fixedly connected with pivot 36, the one end of pivot 36 runs through to clamp support 3's outside, pivot 36 is located the outside one end fixedly connected with knob 37 of clamp support 3, the one end of card strap 31 runs through behind guiding hole 32 with pivot 36 fixed connection.

The utility model discloses in, in the use, embolia two card strap 31 respectively with cable earth connection 2 earlier in cable body 1, then through rotating knob 37, thereby drive pivot 36 and rotate and make clamp support 3 about two sides and be located the outside card strap 31 of cable body 1 and be rolled up the surface of pivot 36 gradually, after locking cable body 1, ratchet 34 receives the tension that produces when card strap 31 resets and can reverse, and pawl 35 card is gone into in ratchet 34 surface, make ratchet 34 unable reverse, thereby fixed card strap 31, lock through two card strap 31 and fix cable body 1 or cable earth connection 2, thereby avoided single card strap 31 thinner or cable body 1 or cable earth connection 2 that the too big pressure caused to take place to deform;

in addition at the in-process of installation clamp, it is less at clamp or installation space, when inconvenient staff installs, the staff can directly rotate knob 37 area and lock, do not need the pulling card strap 31, can also use the screwdriver to rotate knob 37, and when knob 37 rotated, can drive another knob 37 of bottom and rotate, lock two card straps 31 in step, the staff can both adjust two knob 37 about clamp support 3 in the upper and lower arbitrary one side of clamp support 3, thereby it locks four card straps 31 to be more convenient.
