Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, intactly description; Obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The connection sketch map of the link gold utensil that the sketch map of the link gold utensil that Fig. 1 provides for the utility model embodiment, Fig. 2 provide for the utility model embodiment.
The utility model embodiment provides a kind of link gold utensil, is used to be arranged between insulator string 1 and the high-tension line tower, wherein: the link gold utensil comprises swivel nut link and screw thread link; One end of swivel nut link is provided with first connector that is used to connect high-tension line tower, and the other end is provided with screw thread slotted hole 2; One end of screw thread link is provided with second connector that is used to connect insulator string 1, and the other end is provided with screw thread stock 3; The part spiral is in screw thread slotted hole 2 at least for screw thread stock 3, and formation is threaded.
Being threaded has the characteristics of self-locking, does the time spent only receiving radial load, and the frictional resistance that forms between two parts that are threaded is big, break-off can not occur, thus make be threaded reliable.
The link gold utensil that the utility model embodiment provides has swivel nut link and screw thread link, and the screw thread stock of screw thread link at least the part spiral at the screw thread slotted hole of swivel nut link.Regulate at needs under the situation of wire tension,, can realize the adjustment of distance between insulator string and the high-tension line tower, and then regulate the tension force of lead through regulating the length that is threaded of screw thread stock and screw thread slotted hole.When overtension, the screw thread stock is screwed out certain distance from the screw thread slotted hole, otherwise, the certain distance of precession then.The link gold utensil that the utility model embodiment provides, simple in structure, easy to use, according to different operating mode demands, can arbitrarily design the length of screw thread stock and screw thread slotted hole, to satisfy the length adjustment needs.
