Abstract
The invention discloses a double-end connecting piece for the oil exploitation field, which comprises a bolt stem, wherein a plurality of sections of threads are arranged on the bolt stem. In the double-end connecting piece for the oil exploitation field, the matching of the threads of the two ends and a nut is utilized to fix a part, the threads of the two ends are the same, so the stresses of the bolt stem are the same, so a balancing stress effect is realized, the fixing effect is better, and the service life of a fastener is longer.
Description
Technical field
The present invention relates to a kind of double end link, especially relate to a kind of double end link that is used for field of petroleum exploitation, belong to mechanical field.
Background technique
Fastening piece generally is used for mining machinery, bridge, and automobile, motorcycle, boiler steel structure, tower crane, large-span steel and heavy construction etc. are used to connect mechanical fixed connection function.Divide common with articulation hole is arranged.Common main reach to stressed, also can load bearing requirements not high be lateral stressed.The bolt that articulation hole is used will cooperate with the size in hole, is used in when receiving transverse force.Hexagon head is arranged, round end, square spigot, countersunk head or the like.Wherein hexagon head is the most frequently used.General countersunk head is used in and requires to connect
Back smooth surface there is not the place of projection, because countersunk head may be screwed in the part.Round end also can be screwed in the part.The screwing force of square toes can be greatly, but size is very big.Adopt an end to fix, because discontinuity causes bolt fracture or distortion easily.
In order to satisfy the needs that back locking is installed, have head porose in addition, bar portion is porose, unlikely getting loose when these holes can make bolt vibrated.The connecting-rod bolts of diesel engine are disposable, do not allow to reuse.If the repeated use connecting-rod bolts, because stressed bigger, bolt elongates, and very easily causes bearing shell that the tile kilning accident takes place owing to bolton strength is not enough; Simultaneously because the fastening force quantity not sufficient, the matching gap increase of bearing shell and crankshaft journal causes engine oil pressure low, causes the excessive wear of bearing shell and the tile kilning accident occurs.Diesel engine is a highly-intensified diesel engine, and the connecting rod load that is hit is bigger, and more common diesel engine is many greatly, and connecting-rod bolts are reused and very easily to be caused fracture, break engine cylinder, cause motor to be scrapped.Though the unit that has has changed connecting-rod bolts, fracture defect has also appearred, and there are other motor connecting-rod bolts that are in operation to rupture suddenly.
Traditional bolt is owing to be to have only an end that screw thread is arranged; In connection procedure, one is fixed on the parts as fixing device, and the other end cooperates with nut; Owing to the vibrations of parts or reason such as lateral stressed; Shearing force takes place easily, bigger to the damage ratio of screw rod, so must adopt a kind of double end link to come connected element.
Summary of the invention
The objective of the invention is to overcome the shortcoming and defect of above-mentioned existing technology; A kind of double end link that is used for field of petroleum exploitation is provided, and this double end link utilizes the screw thread at two ends to cooperate with nut, and parts are fixed; The screw thread at two is identical, and to make that bolt column receives stress also identical; Reach the effect of stress equalization, fixed effect is better, makes the longer service life of fastening piece.
The object of the invention is realized through following technical proposals: be used for the double end link of field of petroleum exploitation, comprise bolt column, said bolt column is provided with the plurality of sections screw thread.
Said screw thread is separately positioned on the two ends of bolt column.
The diameter of said bolt column is greater than the big footpath of screw thread.
Be provided with Marking ring between said bolt column and the screw thread, the diameter of said Marking ring is less than the path of screw thread.
Said bolt column, screw thread and Marking ring all adopt stainless steel to process.
In sum, the invention has the beneficial effects as follows: this double end link utilizes the screw thread at two ends to cooperate with nut, and parts are fixed; The screw thread at two is identical, and to make that bolt column receives stress also identical; Reach the effect of stress equalization, fixed effect is better, makes the longer service life of fastening piece.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Mark and corresponding component title in the accompanying drawing: 1-nut; 2-Marking ring; 3-bolt column; 4-screw thread.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is done further detailed description, but mode of execution of the present invention is not limited only to this.
Embodiment:
As shown in Figure 1, be used for the double end link of field of petroleum exploitation, comprise bolt column 3, said bolt column 3 is provided with plurality of sections screw thread 4.Screw on screw thread 4 through nut 1, a plurality of parts are fixed together,,, avoided unbalance stress and bolt column 3 distortion that cause or fracture so the stress intensity that receives is also identical because the screw thread at two ends 4 is measure-alike.
Said screw thread 4 is separately positioned on the two ends of bolt column 3.Bolt column 3 is penetrated in the through hole of two or more parts, the screw thread 4 through being arranged on bolt column 3 two ends is fixed two parts with screwing of nut 1, can be by that analogy fixing to a plurality of parts that are provided with through hole.
The diameter of said bolt column 3 is greater than the big footpath of screw thread 4.Bolt column 3 mainly is the contact position that is used at two parts, is bearing bigger stress, so the diameter of bolt column 3 is bigger than the big footpath of screw thread 4, could in the parts working procedure, parts be fixed.
Be provided with Marking ring 2 between said bolt column 3 and the screw thread 4, the diameter of said Marking ring 2 is less than the path of screw thread 4.Every suit fastening piece all has the model of oneself, and model need neither influence the work of part relatively a suitable position; And it is attractive in appearance; Through Marking ring is set, can prevent to be worn in use, on visual effect, also let the people come into plain view simultaneously; When choosing more efficient and convenient, avoided fuzzy and time of delaying of mark.
Said bolt column 3, screw thread 4 and Marking ring 2 all adopt stainless steel to process.Fastening piece is sometimes installed and not replacing, under different working environments in daily Environmental Conditions for a long time; Because the comprehensive function of acid, alkali, moisture or grease; Very easily getting rusty becomes fragile, thereby causes bulk strength to change, and influence is fixing to parts; The employing stainless steel is processed, and stainless steel can not produce burn into spot corrosion, corrosion or wearing and tearing.Because stainless steel has good anti-corrosion, so it can make structure member for good and all keep the integrity of engineering design.Chromium stainless steel also integrates mechanical strength and deep drawing quality, is easy to the manufacturing of parts, can satisfy architect and structural design personnel's needs.Fastening piece can not cause solid failure yet under situation about not changing for a long time.
Take aforesaid way, just can realize the present invention preferably.
