Abstract
The utility model discloses an abnormal-shaped connecting piece for a specific position, which comprises a screw rod. Threads are arranged at one end of the screw rod and a fixing device is arranged at the other end of the screw rod. The abnormal-shaped connecting piece is simple in structure, low in production cost and high in abrasion-resisting performance, corrosion-resisting performance and intensity, has wide purposes in device installation of the petroleum industry field, and can meet requirements of the specific position in the petroleum industry field.
Description
Technical field
The utility model relates to a kind of special-shaped link, especially relates to a kind of special-shaped link that is used for special position.Belong to mechanical field.
Background technique
Outer surface has been cut the spiral fluted cylinder or has been cut conical surface spiral fluted circular cone and has been called screw rod, and screw rod has different heads, like outer-hexagonal screw rod, big flat screw rod, hexagon socket head cap screw or the like.By head and screw rod (having externally threaded cylindrical body) one type of fastening piece dimerous, need nut to cooperate, be used to be fastenedly connected two parts that have through hole.This Connecting format is called bolt and connects, and as screwing off nut from bolt, can make these two parts separately again, is to belong to removably connect so bolt connects.Screw is to utilize the circular rotation in inclined-plane of object and the physics and the mathematical principle of frictional force, the instrument of fastening by easy stages implements parts.Screw is the general saying of fastening piece, daily pet phrase.Screw is an industrial necessity indispensable in the daily life: like the minimum screw of uses such as photographic camera, glasses, clock and watch, electronics; Screw as one of TV, electric product, musical instrument, furniture etc.; Then use large-scale screw, nut as for engineering, building, bridge; Traffic utensil, aircraft, electric car, automobile etc. then are big primary screw and use.Screw is born vital task in industry, as long as exist industry on the earth, then the function of screw is important forever.Screw is the common invention in people's productive life over the past thousands of years, and according to application, it is human first invention.Bolt is very extensive in practical applications; Generally it is divided into plain bolt and heterotypic bolt; The standard of dividing is everyly to have the bolt of NBS all to should be plain bolt (like hexagon head bolt, socket cap hexagon socket head cap screw, stud bolt, straight groove bolt, cross recess bolt, square toes Cock screw stone bolt etc.); Do not have the bolt of national regulation to claim heterotypic bolt, it generally is used in special occasion, special purposes, also need special tool go fastening with unscrew it.In the field of petrochemical industry, some special positions use plain screw can't reach usage requirement, in the mounting point limit shape of plain screw.
The model utility content
The purpose of the utility model is to overcome the shortcoming and defect of above-mentioned existing technology, and a kind of special-shaped link that is used for special position is provided, and this abnormal shape link is simple in structure; Cost of production is low; Wear-resisting property is high, and decay resistance is high, and intensity is high; In the equipment in petroleum industry field is installed, purposes is widely arranged, can satisfy the demand of petroleum industry field specific position.
The purpose of the utility model realizes through following technical proposals: be used for the special-shaped link of special position, comprise that an end is provided with threaded screw rod, the other end of said screw rod is provided with fixing device.
Said screw rod outer surface is provided with groove, the center line of said groove and the central lines of screw rod.
Said fixing device is provided with fixing column at the end away from screw rod.
Said fixing device and screw rod weld together.
Said screw rod and fixing device all adopt the nitriding steel material to process.
In sum, the beneficial effect of the utility model is: this abnormal shape link is simple in structure, and cost of production is low; Wear-resisting property is high, and decay resistance is high, and intensity is high; In the equipment in petroleum industry field is installed, purposes is widely arranged, can satisfy the demand of petroleum industry field specific position.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark and corresponding component title in the accompanying drawing: 1-screw thread; 2-groove; 3-screw rod; 4-fixing device; 5-fixing column.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the mode of execution of the utility model is not limited only to this.
Embodiment:
As shown in Figure 1, be used for the special-shaped link of special position, comprise that an end is provided with the screw rod 3 of screw thread 1, the other end of said screw rod 3 is provided with fixing device 4.In the petroleum industry field, parts are fixed screw thread 1 and nut screwing through special-shaped link.
Said screw rod 3 outer surfaces are provided with groove 2, the center line of the center line of said groove 2 and screw rod 3
Overlap.Nut is when screwing; Sometimes be to adopt the means of machinery to screw, operator sense greatly and cause screwing excessively, make nut break to cause screw insecure; So need to adopt an equipment to control the degree of depth that screws, can control the degree of depth of nut screwing through groove 2.
Said fixing device 4 is provided with fixing column 5 at the end away from screw rod 3.Convenient through fixing column 5 with screw rod 3 location, guaranteed that screw rod 3 can not squint, and confirms installation precision.
Said fixing device 4 welds together with screw rod 3.Fixing device 4 is used for fixing with equipment, and screw rod 3 and fixing device 4 structure that is welded as a whole is in use more firm, increases the stability and the working life of screw rod 3.
Said screw rod 3 all adopts the nitriding steel material to process with fixing device 4.Be used for the utility model and be mounted in oil equipment; The environment that oil equipment is worked is more abominable; All be under some extreme weather environments, thus to the requirement of material than higher, adopt the nitriding steel material to process; Can increase the wear resistance and the corrosion resistance of screw rod 3 and fixing device 4, prolong working life.
In the equipment in petroleum industry field; Because its specific environment of installing and using, conventional link can't satisfy its requirement, has gone out the utility model through a series of Practical Design; The utility model can be quick installed on the oil equipment; And can adapt to the working environment of oil equipment, simultaneously because its low cost of manufacture, it is also convenient to change.
Take aforesaid way, just can realize the utility model.
