Abstract
The utility model relates to a special tightening component for the underground pipe. The utility model comprises a fixed nut, a movable nut and a bolt; the fixed nut and the movable nut are provided in the two ends of the bolt; and a rotating proof positioning pin is provided between the fixed nut and the bolt. The utility model has the advantages of rational design, simple structure, easy to be operated, convenient to be used, hard and abrasion proof compared with the prior art; therefore the utility model has a good popularity value.
Description
1, technical field
The utility model relates to a kind of metal fastenings, specifically a kind of corrosion-resistant under ground piping special fastener of using under ground piping or the outdoor equipment of being used for.
2, technical background
The various metal fixings of prior art are molded with steel heating impact forging, and then screw thread is gone up in processing, in use existing deficiency is that corrosion resistance is relatively poor, in the fastening construction of pipe fitting in the under ground piping, grow in underground service time one, the serious corrosion of fastening piece meeting of steel, construction brings a lot of difficulties to pipeline maintenance.From material, ironcasting is more corrosion resistant, so most under ground piping adopts cast iron tube more, does not also have at present and the corrosion-resistant special fastener of the matching used cast-iron pipe of cast-iron pipe.
3, summary of the invention
The purpose of this utility model provides a kind of matching used corrosion-resistant under ground piping special fastener of under ground piping that is.
The purpose of this utility model realizes in the following manner, can not impact forging press machining characteristics according to ironcasting, adopt the machine shaping respectively of bolt and nut machine, then the end of a nut by locating stud and screw thread and screw rod is not fixed together and makes screw rod, join a traveling nut at the other end of screw rod and get final product with six sides.
Accompanying drawing is the structural representation of under ground piping special fastener.
4, description of drawings
Explain below with reference to Figure of description under ground piping special fastener of the present utility model being done.
Under ground piping special fastener of the present utility model, its structure are to be made of set screw nut 3, traveling nut 1 and screw rod 2, and set screw nut 3 and traveling nut 1 are arranged on the two ends of screw rod 2, are provided with anti-rotation locating stud 4 between set screw nut 3 and the screw rod 2.
5, mode of execution
Its processing and fabricating of under ground piping special fastener of the present utility model is very simple and convenient, processing and fabricating gets final product shown in the by specification accompanying drawing, add man-hour, can be with the screw rod than long bolt blank processing specific length of cast molding, nut blank with cast molding is processed into nut, then a nut is screwed in the end of screw rod as set screw nut, stamps blind hole between nut and screw rod, hammer into the anti-rotation locating stud, at last the traveling nut lemon is finished product at the other end of screw rod.
Under ground piping special fastener of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, characteristics such as corrosion-resistant easy to use, firm, thereby, have good value for applications.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
