Abstract
The utility model belongs to the technical field of the fastener, specifically disclose an eccentric bolt, including bolt body and nut, the bolt body bolt head, shank of bolt, eccentric block and nut, bolt head and shank of bolt fixed connection, shank of bolt run through the eccentric block, the shank of bolt include the polished rod section and with nut matched with screw thread section, eccentric block and polished rod section normal running fit. The utility model discloses an eccentric bolt can carry out off -centre and concentric regulation to the axial lead of shank of bolt and the axial lead of bolt head.
Description
Technical field
This utility model is related to technical field of fastening, and in particular to a kind of eccentric bolt.
Background technology
Bolt is the cylindrical threaded securing member of adapted nut, by head and screw rod (carrying externally threaded cylinder)
Class securing member dimerous.Bolt generally needs to be used with nut screw connection when specifically used, for being fastenedly connected two
The individual part with through hole.
Bolt connection belongs to the one kind in being detachably connected, and nut is connected with bolt by silk tooth, and nut can be from bolt
Screw off.
The species of bolt has a lot, generally there is plain bolt and eccentric bolt.Conventional eccentric bolt generally refers to screw rod
The bolt not conllinear with the axial line of nut, nut.Eccentric bolt is mainly used in automotive suspension, joins to the positioning for adjusting suspension
Number.But in practical work process, the connection between some parts needs to use plain bolt, however, between some parts
Connection need eccentric bolt, this is accomplished by operator, and standby two types bolt is bothered very much.
Utility model content
The purpose of this utility model is the axial line for providing a kind of axial line of achievable shank of bolt and bolt head, is carried out
The eccentric eccentric bolt with concentric regulation.
To reach above-mentioned purpose, base case of the present utility model is：A kind of eccentric bolt, including bolt body and spiral shell
Mother, the bolt body, including bolt head, shank of bolt, eccentric block and nut, the bolt head is fixedly connected with shank of bolt, spiral shell
Tightening latch runs through eccentric block, and the shank of bolt includes light bar segment and the thread segment being engaged with nut, the eccentric block and light bar segment
It is rotatably assorted.
The advantage of this programme：During specifically used eccentric bolt, when needing to make plain bolt performance, rotating eccentricity block,
Make the geometry axial line of shank of bolt conllinear with the axial line of bolt head.
When needing to use eccentric bolt performance, rotating eccentricity block makes the geometry axial line of shank of bolt and the axle of bolt head
Heart line is eccentric.
The eccentric bolt of this programme can select eccentric bolt to be to make plain bolt performance also according to the concrete condition of connector
It is eccentric bolt performance.
Preferred version one：Based on scheme preferred version, the shape of cross section of the light bar segment is circle, it is described partially
The cross section of heart block is also circle, and the eccentric block is provided with the rotating hole matched with light bar segment, the rotating hole and light bar segment
Cylindrical inscribe.The advantage of this programme is：All the time light bar segment outer surface is surrounded when eccentric block rotates, reliability is higher.
Preferred version two：Based on scheme or preferred version one preferred version：The nut is self-locking nut, to even
Fitting fastening effect more preferably, designing special locking measures relaxation effect is can reach.
Preferred version three：Preferably two preferred version：The axial line of the shank of bolt and the axle center of bolt head
Line is eccentric；When the eccentric block axial line is conllinear with bolt head axial line, the external diameter of thread segment is with the external diameter of eccentric block in bolt
Projection on head is overlapped.The advantage of this programme：Processing and fabricating, eccentric block and shank of bolt is facilitated to adopt same bar system
Make.
Description of the drawings
Fig. 1 is a kind of structural representation of eccentric bolt embodiment of this utility model；
Fig. 2 is A-A sectional views in Fig. 1；
Fig. 3 is B-B sectional views in Fig. 1.
Specific embodiment
This utility model is described in further detail below by specific embodiment：
Reference in Figure of description includes：Nut 1, eccentric block 2, bolt head 3, shank of bolt 4.
Embodiment is substantially as shown in Figure 1, Figure 2, Figure 3 shows：A kind of eccentric bolt, including bolt body and nut 1, bolt sheet
Body, including bolt head 3, shank of bolt 4, eccentric block 2 and nut 1.The nut 1 is self-locking nut.Bolt head 3 and the one of shank of bolt 4
Molding, shank of bolt 4 runs through eccentric block 2.Shank of bolt 4 includes light bar segment and the thread segment being engaged with nut 1, eccentric block 2 and light
Bar segment is rotatably assorted.
The shape of cross section of light bar segment is circle, and the cross section of eccentric block 2 is also circle, and eccentric block 2 is provided with and polished rod
The rotating hole that section matches, the rotating hole and the cylindrical inscribe of light bar segment.
As shown in figure 3, the axial line of shank of bolt 4 is eccentric with the axial line of bolt head 3；When eccentric block 2 is in common bar position,
Projection of the external diameter of thread segment with the external diameter of eccentric block 2 on bolt head 3 is Chong Die.
During specifically used eccentric bolt, when needing to make plain bolt performance, rotating eccentricity block 2 makes the several of shank of bolt 4
What axial line is conllinear with the axial line of bolt head 3.
When needing to use eccentric bolt performance, rotating eccentricity block 2 makes the geometry axial line and bolt head 3 of shank of bolt 4
Axial line is eccentric.
The eccentric bolt of this programme can select eccentric bolt to be to make plain bolt performance also according to the concrete condition of connector
It is eccentric bolt performance.
Above-described is only embodiment of the present utility model, the general knowledge here such as known concrete structure and characteristic in scheme
Excessive description is not made.It should be pointed out that for a person skilled in the art, in the premise without departing from this utility model structure
Under, some deformations and improvement can also be made, these should also be considered as protection domain of the present utility model, and these are all without impact
Effect and practical applicability that this utility model is implemented.This application claims protection domain should be with the content of its claim
It is defined, specific embodiment in description etc. records the content that can be used for explaining claim.
