Authorization Notice No. is that the utility model patent document of CN203225139U discloses a kind of guy insulator, comprises two beckets and insulator; Two described beckets are nested and are not in contact with each other, and one end that two described beckets are nested is fixing by described insulator encapsulating, and the other end of two described beckets stretches out outside described insulator, and residing for two described beckets, anchor ring forms an angle; Each becket is made up of at the catch of U-shaped Metallic rod openend with being connected with U-shaped Metallic rod; The openend of described U-shaped Metallic rod and catch are fixed by described insulator encapsulating, and the curved end of described U-shaped Metallic rod is stretched out outside described insulator; The two ends of each described U-shaped Metallic rod are bolted with the nut that anti-stop tab departs from from U-shaped Metallic rod.
The ubiquitous defect of traditional guy insulator is: easily broken, tensile strength is low, and difficulty of processing is high.
Utility model content
The utility model provides a kind of guy insulator, rational in infrastructure, and tensile strength is high, can carry larger pulling force, thus can extend the useful life of product.
The technical solution of the utility model is:
A kind of guy insulator, comprise the first drawing piece and the second drawing piece that cooperatively interact, the connecting portion of two drawing pieces is enclosed with insulator; Connecting portion at two drawing pieces:
With connecting plate on described first drawing piece, with through hole on this connecting plate;
With the pull bar through described through hole on described second drawing piece, this tie rod end is provided with the expansion-head being hampered by described through hole.
Described first drawing piece and the second drawing piece are not in contact with each other.Gap is left, this gap-fill insulator between described expansion-head and connector.Described clear size of opening is greater than pull bar diameter, and pull bar does not contact with connecting plate.
Described expansion-head and pull bar can be one-body molded, also can be threaded or weld.When expansion-head is connected with pull rod screw, easy for installation and adhesion is strong, more firm than welding.
As preferably, described expansion-head is the baffle plate with tie rod end threaded engagement.
Be filled with insulator between described baffle plate and connecting plate, there is between baffle plate and connecting plate larger lifting surface area, also easier by the dispersion of the active force of two drawing pieces, avoid local pulling force excessive, add the tensile strength of insulator.
As preferably, described baffle plate is oval.As preferred further, the major axis of described ellipse and the first drawing piece place plane orthogonal.
As preferably, described first drawing piece comprises U-shaped bar and described connecting plate, and two terminations of U-shaped bar are run through and are fixed on described connecting plate, and U-shaped bar extends insulator away from the position of two terminations.
As preferably, described through hole is positioned in the middle part of connecting plate.
As preferably, described second drawing piece comprises draw ring and described pull bar, and described pull bar extends to insulator exterior away from one end of expansion-head and is fixedly connected with described draw ring.
In guy insulator of the present utility model, have employed the first tension part of band connecting plate and the second connector of band pull bar, described connecting plate has through hole, and described pull bar passes described through hole and is provided with the expansion-head being hampered by described through hole in end.Guy insulator reasonable in design of the present utility model, handling ease, and also between connecting plate and expansion-head, lifting surface area is large, easily by the active force dispersion between two tension parts, can carry larger pulling force, thus can extend the useful life of product.
