Description
Technical field
The utility model belongs to engineering construction or mechanical package accessory applied technical field, and in particular to a kind of high intensity spiral shell
Bolt is suitable for accurate to progress such as engineering construction frame, Automatic manual transmission assembling or petroleum pipeline assemblings, stable and efficient assembly
Operation.
Background technology
Bolt：Machine components, the cylindrical threaded fastener of adapted nut.By head and screw rod（With external screw thread
Cylinder）One kind fastener dimerous, need to coordinate with nut, for being fastenedly connected two parts for carrying through-hole,
This type of attachment claims to be bolted, and such as nut is screwed off from bolt, and the two parts can be made to separate, therefore is bolted
It is to belong to be detachably connected.
By the force way point of connection：It is point common and have articulation hole.By head shape point：There is turret head, circle
Head, square spigot, countersunk head etc..Wherein turret head is most common, and general countersunk head is used in the place for requiring connection.It rides
Bolt English name is U-bolt, and criteria of right and wrong part, shape is U-shaped so also referred to as U-bolt, both ends have screw thread can be with nut
In conjunction with being mainly used for the leaf spring of fixed tube such as water pipe or tablet such as automobile, since it fixes the mode of object as people rides
It is the same in horse back, therefore referred to as U-bolts.It is divided into two class of full thread and non-full thread by reach.It is divided by the tooth form of screw thread
Two class of coarse thread and closely-pitched, coarse thread type are not shown in the mark of bolt.Bolt is divided into 3.6 according to performance rate, 4.8,5.6,
5.8,8.8,9.8,10.9,12.9 8 grades, the bolt materials that (contain 8.8 grades) wherein 8.8 grades or more be low-carbon alloy steel or in
Carbon steel is simultaneously thermally treated (quenching+tempering), is generally called high-strength bolt, 8.8 grades or less (being free of 8.8 grades) common name plain bolts.It is general
Logical bolt can be divided into A, B, C three grades according to precision is made, and A, B grades are burnished bolt, and C grades are rough bolt.For steel knot
Structure connection bolt, in addition to especially indicating, generally common crude C grade bolts, the method for different levels processing has differences,
Usually corresponding processing method is as follows：1. A, the tightening latch of B grade bolts is formed by lathe process, surface is smooth, accurate size, material
Performance rate is 8.8 grades, and fabrication and installation are complicated, higher price, and 2. C grade bolts are made of unprocessed round steel, and size is not smart enough
Really, material property grade is 4.6 grades or 4.8 grades.It is deformed greatly when shear connections, but easy for installation, production cost is low, is chiefly used in
Being fixed temporarily when tensile connection or installation.
Bolt is usually applied to cryogenic high pressure valve, pressure pipeline, fluid engineering, oil drilling and extracting equipment, oil field equipment etc.
Field, the often such as valve industry in the occasion or tool for dismantle connection use on folding bike, perambulator, user
Just, fast had a wide range of application using connection fastening is played with matching nut.
But the bolt of traditional structure, on the one hand its design is unreasonable, installing and dismounting victory inconvenient for use, while it is for a long time
The phenomenon that easily being deformed after use, and high temperature resistant, poor corrosion resistance, cause service life is short to need periodic inspection, influence it
Service efficiency etc., on the other hand, reinforcing rib structure design lead to poor toughness, short life after overall package, and this is current institute
Urgently to be resolved hurrily.
Therefore, based on the above issues, the utility model provides a kind of high-strength bolt.
Utility model content
Purpose of utility model：The purpose of this utility model is to provide a kind of high-strength bolt, and design structure is reasonable, whole
All steel structure is used in combination, and corrosion-resistant, high temperature resistant, toughness are strong, and service life is long, and without often maintenance service efficiency
Height, no deformation or the appearance of phenomenon of rupture, ensure the safety of cooperating therewith package assembly.
Technical solution：The utility model provides a kind of high-strength bolt, including adjusting ball head, and connect with adjusting ball head
Connecting pole is supported, and the first conical limit circle being connect with support connecting pole one end, and is connect with first conical limit circle one end
Whorl brace rod, and the second conical limit circle for being connect with whorl brace rod one end, and connecting with second conical limit circle one end
The auxiliary positioning plate connect, and one group of auxiliary stopper hole being symmetricly set in auxiliary positioning plate；The whorl brace rod, auxiliary are fixed
Position plate, supports the diameter of connecting pole to successively decrease successively at adjusting ball head；The auxiliary positioning plate is set as semicircular structure.
The technical program, the strength bolts further include that both ends connect with the first conical limit circle, whorl brace rod respectively
The auxiliary external screw thread support connecting pole connect, and the auxiliary adjustment nut supported in auxiliary external screw thread on connecting pole is set.
The technical program, the high-strength bolt further includes the first semicircle for being symmetricly set on auxiliary positioning plate both sides
Shape spill limiting slot, the second semi-cylindrical female limiting slot.
Compared with prior art, a kind of advantageous effect of high-strength bolt of the utility model is：Its design structure is closed
