Description
Technical field：
This utility model is related to high-strength technical field of fastening, more particularly to a kind of rustless steel high-strength bolt.
Background technology：
Securing member is commercially also referred to as standard component, is to be fastenedly connected two or more parts or component to become
The general name of the class machine components adopted during one entirety, is characterized in that description is various, and performance purposes is different, Er Qiebiao
It is standardization, seriation, unitized strong.Securing member is most widely used mechanical basic part, various machineries, equipment,
Above vehicle, ship, railway, bridge, building, structure, instrument, instrument, instrument and articles for use etc., it can be seen that miscellaneous
Securing member.
Bolt is one of modal securing member, and it is made up of head and screw rod.The screw rod of bolt is cylindrical, above carries
External screw thread can be used with nut collocation.Screw bolt and nut is used in conjunction with, and can connect and fix two parts with through hole.Bolt
Bolt connection is also referred to as with the form of being connected of nut.
The connection of screw bolt and nut be not it is permanent be fixedly connected, turn nut buckle only bolt latter two components and fastened
Together, and by nut backing out latter two components from bolt can be freely separating, therefore bolt connection is to be detachably connected.But
Although being that bolt connection motility is high, soundness is often below non-dismountable connection.High-strength bolt is mainly used in steel knot
In structure engineering, for connecting the junction point of steel plates of steel structure, and only limit is intended for single use, be generally used for it is permanently connected, but commonly
High-strength bolt only one of which nut, after prolonged nut can loosen, it is aging, and welding position is compared due to solder side
It is stiff, also can loosen after long-time use；Common high-strength bolt is not provided with the screw rod between packing ring and bolt head
Screw thread, is smooth, cylindrical peripheral surface, easily makes bolt slide, and reduces its fastening ability.Therefore the performance of high-strength bolt has much room for improvement.
The content of the invention：
This utility model is in order to overcome drawbacks described above present in prior art, there is provided a kind of rustless steel high-strength bolt.
To solve the above problems, the utility model proposes rustless steel high-strength bolt include bolt body, the bolt sheet
Body one end be bolt head, one end be screw rod, on the screw rod near bolt head one end be disposed with the first packing ring, second
Packing ring, spring washer, the first nut and the second nut, are provided with screw thread, the end of the screw rod on the outer surface of the screw rod
A manhole is provided with, the axis of the manhole is vertical with the axis of the screw rod, is inserted with the manhole
Vertically 180 ° of bending is formed by a steel wire for one split pin, the split pin, and the component for needing fastening is located at the first packing ring and second
Between packing ring.
In above-mentioned technical proposal, the rustless steel high-strength bolt is made by SUS316.
In above-mentioned technical proposal, female thread and the screw flight of first nut and the second nut match.
This utility model has the advantages that and advantage compared with prior art：
1) the utility model proposes rustless steel high-strength bolt made using SUS316, the plasticity of SUS316, toughness, cold change
Property, welding technological properties is good, elevated temperature strength is good, corrosion resistance is good, be conducive to improve rustless steel high-strength bolt performance, end
Life is non-maintaining.
2) the utility model proposes the design of rustless steel high-strength bolt split shed pin can effectively improve the high-strength spiral shell of rustless steel
The anti-loosening property of bolt, it is to avoid rustless steel high-strength bolt loose or dislocation after long-term use, is conducive to improving rustless steel high-strength bolt
Security reliability.
Description of the drawings：
Fig. 1 be the utility model proposes rustless steel high-strength bolt structural representation when in use.
Fig. 2 be the utility model proposes rustless steel high-strength bolt split pin place position cross-sectional view.
Explanation is numbered in figure：1st, bolt head；2nd, screw rod；3rd, the first packing ring；4th, second packing ring；5th, spring washer；6th, first
Nut；7th, the second nut；8th, manhole；9th, split pin；10th, by fastening block；11st, channel-section steel.
Specific embodiment：
This utility model is described in further detail below in conjunction with the drawings and specific embodiments：
As shown in Figure 1 and Figure 2, the utility model proposes rustless steel high-strength bolt include bolt body, bolt body one end
It is screw rod 2 for bolt head 1, one end, the first packing ring 3, second packing ring is disposed with from the one end near bolt head 1 on screw rod 2
4th, spring washer 5, the first nut 6 and the second nut 7, are provided with screw thread on the outer surface of screw rod 2, and the end of screw rod 2 is provided with
One manhole 8, the axis of manhole 8 is vertical with the axis of screw rod 2, and a split pin 9, opening are inserted with manhole 8
By a steel wire, vertically 180 ° of bending is formed pin 9, needs the component of fastening to be located at the first packing ring 3 and the by fastening block 10 and channel-section steel 11
Between two packing rings 4, the first packing ring 3 and second packing ring 4 make not abraded by nut by the surface of fastening block 10 and channel-section steel 11, disperse spiral shell
Female pressure to connected piece.
Rustless steel high-strength bolt is made by SUS316.
The female thread of the first nut 6 and the second nut 7 matches with the screw thread of screw rod 2.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
This utility model has been described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
