Abstract
The present invention relates to a body-separated type one-way bolt fastener, belonging to the field of mechanical assembly technology. Said bolt body is composed of three portions, including two side bar bodies and one intermediate bar body, said three portions can be combined into a bolt whole body. The outer profile of cross-section of main body portion of every side bar body is equipped with a section of minor arc, said curved face has screw threads. Said intermediate bar body is mainly used for preventing side bar body from falling and has anti-drawing measure. When two side bar bodies and intermediate bar body are combined together, the cross-section of combined bolt whole body is circular, and its curved surface has screw threads, so that when said three portions are combined into a bolt whole body, said bolt whole body can be fixed by using general nut.
Description
Invention field
The present invention relates to a kind ofly can belong to the mechanical assembly technique field from the unidirectional fastening split type bolt fastener of a side.
Background technique
Common bolt fastener generally is made up of nut, screw rod.Need be during installation at a side turnbuckle or a nut, from opposite side spanner binding nut or nut screwing clamping.Usually installation personnel can touch the both sides of fastened object, but for particular application, and such as the structure that the tubular structure or an end of sealing is difficult for touching, the use of plain bolt is very limited.
Summary of the invention
Can not carry out fastening deficiency from monolateral in order to overcome existing bolt, the invention provides a kind of can be from a side unidirectional fastening split type bolt fastener and assembly method thereof.This fastening piece can carry out unidirectional assembling easily, and size can be with reference to existing plain bolt Fastener products.
A kind of split type one-way bolt fastener that the present invention proposes is characterized in that: described bolt fastener is by two side rod bodies (1), (3), and the middle body of rod (2) three parts are formed; Two side rod bodies (1), (3) and the middle body of rod (2) lump together, and the bolt body of rod cross section of composition is circular, and curved surface has screw thread, guarantee that three parts are synthetic can fix with plain nut when whole.
In above-mentioned one-way bolt fastener, the cross section external frame of described two side rod bodies (1), (3) shaft part has one section minor arc, and this minor segment has screw thread, so that by the plain nut fixed core;
In above-mentioned one-way bolt fastener, an end of described two side rod bodies (1), (3) has herniated disk (4), and herniated disk (4) external frame is semicircle or polygonal; When two side rod bodies (1), (3) when lumping together, the external frame maximum diameter that two herniated disks are formed guarantees to pass through from hole.
In above-mentioned one-way bolt fastener, behind the body of rod (2), two herniated disks (4) should be able to block the installation material hole edge, prevent bolt falling in the middle of sandwiching.
In above-mentioned one-way bolt fastener, one-way bolt fastener can be made by metal or plastics, and the metallic material of making fastening piece can be steel or aluminum alloy.
The invention has the beneficial effects as follows: on one side the assurance personnel can operate at the thing that is assembled that touches easily on the structure, installment work is comparatively simple.This bolt fastener can be used for fields such as construction engineering, mechanical engineering, aviation industry, shipping industry.
Description of drawings
Fig. 1 is split bolt arrangement figure of the present invention.
Fig. 2 is the embodiments of the invention graphics.
Among the figure: 1. side rod body, 2. in the middle of the body of rod, 3. side rod body, 4. end nipple placing, 5. side rod body rod body part.
Embodiment
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
For solving unidirectional assembly problem, the technical solution used in the present invention is: plain bolt is changed into by three parts form, and two side rod bodies and a middle body of rod, three parts can consist of a bolt integral body.The cross section external frame of two side rod body rod body parts guarantees that one section minor arc is arranged, and this flexure plane section has screw thread.The main effect of the middle body of rod is to prevent that the side rod body from coming off, and middle body of rod cross-sectional profiles guarantees that two sections minor arcs are arranged, and this flexure plane section also has screw thread, in case the middle body of rod is pulled out.When two side rod bodies and the middle body of rod lumped together, the bolt body of rod cross section of composition was circular, and curved surface is carved with screw thread, guaranteed that three parts are synthetic can fix with plain nut when whole.One end of two side rod bodies has herniated disk, and the external frame of herniated disk is semicircle or polygonal, and when two side rod bodies lumped together, the external frame diameter of two herniated disk compositions guaranteed to pass through from hole.Behind the body of rod, two herniated disks should be able to block the installation material hole edge, prevent bolt falling in the middle of sandwiching.The concrete assembly method of this bolt fastener is as follows:
(1) side of easily touching personnel lumps together two side rod bodies, makes the end nipple placing pass through hole.
(2) the middle body of rod is sent in the middle of the side rod body, three parts are synthesized a complete bolt, and this bolt can not deviate from from a side at two herniated disks assurance bolts of end projection.
Plain nut on the sidespin that personnel easily touch is finished fixing.
In Fig. 1, two side rod bodies (1) (3) can make up, the external frame maximum diameter that end nipple placing (4) forms guarantees to pass through hole, the body of rod (2) back forms a standard bolt body in the middle of sandwiching, two herniated disks (4) separately form imperfect nut and block hole edge, and the assurance body of bolt can not deviate from.
In the embodiment shown in Figure 2, earlier with two side rod bodies (1) (3) combination, by installation material hole (left figure); The middle body of rod (2) is added, form a standard bolt body, screw in plain nut from the other end and finish steady job (right figure).
Claims (4)
1. split type one-way bolt fastener is characterized in that: described bolt fastener is by two side rod bodies (1), (3), and the body of rod (2) three parts are formed in the middle of one; Two side rod bodies (1), (3) and the middle body of rod (2) lump together, and the bolt body of rod cross section of composition is circular, and curved surface has screw thread, guarantee that three parts are synthetic can fix with plain nut when whole.
2. one-way bolt fastener according to claim 1 is characterized in that: the cross section external frame of described two side rod bodies (1), (3) main body has one section minor arc, and this minor segment has screw thread
3. one-way bolt fastener according to claim 1 is characterized in that: an end of described two side rod bodies (1), (3) has herniated disk (4), and herniated disk (4) external frame is semicircle or polygonal; When two side rod bodies (1), (3) when lumping together, the external frame maximum diameter that two herniated disks are formed guarantees to pass through from hole.
4. one-way bolt fastener according to claim 1 is characterized in that: behind the body of rod (2), two herniated disks (4) should be able to block the installation material hole edge, prevent bolt falling in the middle of sandwiching.
