The present invention provides a kind of adjustable type bolt, including screw body and the adjusting part for being arranged on screw body periphery；The adjusting part includes at least two sector element, and the sector element constitutes a circumference and is arranged on the periphery of the screw body, and the center of circle is concentric circles in the center of the screw body, the i.e. circumference of sector element composition and screw body；The inwall of the sector element is connected by expansion link with the outer wall of the screw body, and the outer circumferential walls of sector element composition are provided with the screw thread matched with nut.The bolt can meet various sizes of aperture.
Description
Technical field
The present invention relates to a kind of bolt, in particular it relates to a kind of adjustable type bolt.
Background technology
Bolt：A kind of component of machine, the cylindrical threaded fastener of adapted nut.By head and screw rod two parts
One class fastener of composition, need to coordinate with nut, and for being fastenedly connected two parts for carrying through hole, this type of attachment claims spiral shell
Tether and connect.As nut is screwed off from bolt, two parts can be made separated again, therefore bolt connection belongs to and is detachably connected.But
The diameter of existing bolt is all changeless, it is impossible to meet the aperture of various sizes of fixation.
The content of the invention
The present invention, can in order to solve drawbacks described above present in prior art and deficiency there is provided a kind of adjustable type bolt
To meet various sizes of aperture.
In order to solve the above technical problems, the present invention provides a kind of adjustable type bolt, including screw body and it is arranged on screw rod
The adjusting part of body periphery；
The adjusting part includes at least two sector element, and the sector element constitutes a circumference and is arranged on the screw rod sheet
On the periphery of body, and the center of circle is concentric with screw body in the center of the screw body, the i.e. circumference of sector element composition
Circle；The inwall of the sector element is connected by expansion link with the outer wall of the screw body, outside the circumference of sector element composition
Wall is provided with the screw thread matched with nut.
Further, the one end of the expansion link puts in and is fixed on inside screw body, the other end and sector element
It is fixedly linked, and puts in the length and the exposed equal length in outer portion of screw body interior section, during contraction, exposed outside
Point completely into putting in screw body interior section.
Further, the expansion link is provided with positioning component, is used to prevent expansion link from independently stretching when expansion link extends.
Further, the positioning component includes the elastic bumps being arranged on expansion link and is arranged on expansion link wall to lead to
Hole, expansion link carries out elongation localization by the mutual cooperation of elastic bumps and through hole.
Further, extra cell is provided between the two neighboring sector element, the side wall of the sector element is provided with
The groove of extra cell is accommodated, when expansion link shrinks, extra cell is accommodated in groove, during elongation, and extra cell is out of groove
Remove and constitute a circumference with sector element, and outer circumferential walls are provided with screw thread.
Further, there are 2 extra cells between two neighboring sector element, during contraction, adjacent two are accommodated in respectively
In groove on the wall of sector element side.
The advantageous effects that the present invention is reached：A kind of adjustable type bolt disclosed by the invention, passes through expansion link
Stretching can be with the diameter of adjusting screw rod, to be applicable the fixation of different pore size.
Brief description of the drawings
Fig. 1 schematic structural views of the invention；
Fig. 2 contraction state structural representations of the present invention.
Wherein：1 screw body；2 sector elements；3 expansion links；4 elastic bumps；5 extra cells.
Embodiment
With reference to specific embodiment, the invention will be further described.Following examples are only used for clearly illustrating
Technical scheme, and can not be limited the scope of the invention with this.
Patent of the present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1-2, the present invention provides a kind of adjustable type bolt, including screw body 1 and is arranged on outside screw body 1
The adjusting part enclosed；
The adjusting part includes at least two sector element 2, and the sector element 2 constitutes a circumference and is arranged on the screw rod
On the periphery of body 1, and the circumference and screw body 1 that the center of circle is constituted in the center of the screw body 1, i.e. sector element 2
For concentric circles；The inwall of the sector element 2 is connected by expansion link 3 with the outer wall of the screw body 1,2 groups of sector element
Into outer circumferential walls be provided with nut match screw thread.
The one end of the expansion link 3 is put in and is fixed on inside screw body 1, and the other end is fixed with sector element 2
It is connected, and puts in the length and the exposed equal length in outer portion of the interior section of screw body 1, during contraction, exposed outer portion
Completely into putting in the interior section of screw body 1.
The expansion link is provided with positioning component, is used to prevent expansion link from independently stretching when expansion link extends.The positioning
Component includes the elastic bumps 4 being arranged on expansion link 3 and is arranged on through hole on expansion link wall, and expansion link 3 passes through elastic bumps 4
Mutual cooperation with through hole carries out elongation localization.
Extra cell 5 is provided between the two neighboring sector element 2, the side wall of the sector element 2 is provided with receiving
The groove of extra cell, when expansion link shrinks, extra cell 5 is accommodated in groove, during elongation, and extra cell 5 is moved out of groove
Go out and constitute a circumference with sector element, and outer circumferential walls are provided with screw thread.There are 2 additional lists between two neighboring sector element
Member, during contraction, is accommodated in the groove on two adjacent sector element side walls respectively.
The application method of the present invention：When the aperture of fixation body is smaller, expansion link is shunk, the circle that sector element is surrounded
Zhou Zuowei screw rods coordinate with nut.When fixation body aperture pin is big, expansion link elongation, and positioned admittedly by positioning component progress
It is fixed, then extra cell is taken out out of sector element groove, so that extra cell and sector element surround a circumference work
It is that screw rod and nut coordinate.
The present invention is disclosed with preferred embodiment above, so it is not intended to limiting the invention, all to take equivalent substitution
Or the technical scheme that the scheme of equivalent transformation is obtained, all fall within protection scope of the present invention.
