Abstract
The utility model provides an unanimous just screw thread of crotch orientation exposes unanimous hexagonal type theftproof foot nail. It includes main part, circular driving washer and two theftproof fastening nut, the main part comprises fixed disk, main part front portion and main part rear portion. The utility model discloses the effect: because the regular hexagon hole is measure -alike on the position section size who is close to the fixed disk on the main part rear portion and the tower material, consequently only need with the main part rear portion on with crotch mode disect insertion tower material up regular hexagon downthehole can, and the main part can not produce the rotation, in addition, owing to be close to the position length of fixed disk on the main part rear portion and equal with the tower material thickness that the iron tower adopted, consequently not only can once fasten and target in place, easy operation is swift, and simple to operate only needs moreover that an instrument is singlehanded just even can accomplish fastening, and the requirement that the screw thread exposes the length unanimity can be satisfied to the while, checks and accepts 100% one -shot, need not a lot of and adjusts, compares, corrects, need not follow -up rectifying and improving, can save the engineering time, the improvement installation effectiveness.
Description
Technical field
The utility model belongs to electrical facility technical field, particularly relates to a kind of crotch towards consistent and screw thread exposes consistent hexagon anti-theft foot-nail.
Background technology
In power system, steel tower is provided with usually pin nail, its effect is that easy access and operating personnel step on tower, and nowadays Guo Wang company more and more payes attention to standardization, all special regulation is provided with to pin nail in the general system put into effect and high grade project competition, requires very strict.Because anti-theft type pin conventional at present nail all adopts round steel to make, without permanent position during installation, once mounting cannot reach crotch towards consistent requirement upwards, need repeatedly correct, therefore more time and efforts is spent, and due to screw thread long, therefore two bolton positions are not fixed, need carry out fastening with two or more instrument, result makes installation screw thread protruded length inconsistent, need repeatedly adjust and comparison, operate very loaded down with trivial details, inconvenience is installed, checks and accepts rectification often, thus the general system of Guo Wang company and standardized requirement can not be met.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide a kind of crotch towards consistent and screw thread exposes consistent hexagon anti-theft foot-nail.
In order to achieve the above object, the crotch that provides of the utility model is towards consistent and screw thread exposes consistent hexagon anti-theft foot-nail comprises main body, circular shaped motion packing ring and two anti-theft locknut for steels; Described main body is integrally made up of fixed disk, body front part and back body, and wherein body front part is cross section is orthohexagonal long bolt, and outer end is with crotch, and rear end is connected to the side Middle face of fixed disk; One end of back body is connected in the middle part of the another side of fixed disk, and the cross section, position near fixed disk on it is regular hexagon, and middle part and outer end are cylindrical structure, and outer circumference surface is formed with external screw thread; Circular shaped motion gasket sleeve is on the external screw thread of back body; Two anti-theft locknut for steels are threaded on the external screw thread of the back body be positioned at outside circular shaped motion packing ring.
Equal with the thickness of the tower material that steel tower adopts near the span access location length of fixed disk in described back body, and regular hexagon hole measure-alike on sectional dimension and tower material.
The crotch that the utility model provides is towards consistent and screw thread exposes consistent hexagon anti-theft foot-nail has following beneficial effect: due in back body in the position sectional dimension of fixed disk and tower material regular hexagon hole measure-alike, therefore only back body directly need be inserted on tower material in regular hexagon hole in crotch mode upward, and main body can not produce rotation; In addition, because the span access location length near fixed disk in back body is equal with the tower material thickness that steel tower adopts, therefore can not only once fasteningly put in place, simple and quick, easy for installation, and only need an instrument even singlehanded just can complete fastening, the consistent requirement of screw thread protruded length can be met simultaneously, check and accept 100% once to pass through, without the need to repeatedly adjustment, comparison, rectification, without the need to follow-up rectification, engineering time can be saved, improve installation effectiveness, meet the regulation to the installation of pin nail in the general system of Guo Wang company, also can reach standardized requirement simultaneously.
Accompanying drawing explanation
The crotch that Fig. 1 provides for the utility model is towards consistent and screw thread exposes consistent hexagon anti-theft foot-nail structural representation.
Fig. 2 is agent structure schematic diagram on the hexagon anti-theft foot-nail shown in Fig. 1.
Fig. 3 is for the crotch steel tower being installed the utility model and provide is towards consistent and screw thread exposes consistent hexagon anti-theft foot-nail portion structure schematic diagram.
Detailed description of the invention
The crotch provided the utility model below in conjunction with the drawings and specific embodiments is towards consistent and screw thread exposes consistent hexagon anti-theft foot-nail is described in detail.
As shown in Fig. 1-Fig. 3, the crotch that the utility model provides is towards consistent and screw thread exposes consistent hexagon anti-theft foot-nail comprises main body 1, circular shaped motion packing ring 2 and two anti-theft locknut for steels 3; Described main body 1 is integrally made up of fixed disk 4, body front part 5 and back body 6, wherein body front part 5 for cross section be orthohexagonal long bolt, and outer end is with crotch, and rear end is connected to the side Middle face of fixed disk 4; One end of back body 6 is connected in the middle part of the another side of fixed disk 4, and the cross section, position near fixed disk 4 on it is regular hexagon, and middle part and outer end are cylindrical structure, and outer circumference surface is formed with external screw thread; Circular shaped motion packing ring 2 is enclosed within the external screw thread of back body 6; Two anti-theft locknut for steels 3 are threaded on the external screw thread of the back body 6 be positioned at outside circular shaped motion packing ring 2.
Equal with the thickness of the tower material 7 that steel tower adopts near the span access location length of fixed disk 4 in described back body 6, and regular hexagon hole 8 measure-alike on sectional dimension and tower material 7.
The crotch now provided by the utility model is towards consistent and screw thread exposes consistent hexagon anti-theft foot-nail mounting method is described below: during installation by installation personnel by the crotch in body front part 5 towards, then back body 6 is inserted in the regular hexagon hole 8 on tower material 7, now fixed disk 4 will tightly be attached on a side of tower material 7, and due in back body 6 in the position sectional dimension of fixed disk 4 and tower material 7 regular hexagon hole 8 measure-alike, therefore main body 1 can not produce rotation, then on the external screw thread being positioned at the back body 6 outside tower material 7 another side, circular shaped motion packing ring 2 is overlapped, afterwards two anti-theft locknut for steels 3 are threaded on the external screw thread of the back body 6 be positioned at outside circular shaped motion packing ring 2.
