In some special occasions, such as closed cross-section member or inconvenience just cannot when the component that opposite side carries out operation is fastened
Using this conventional bolt and nut method for fastening connection.Accordingly, it would be desirable to research and develop a kind of simple and convenient, the fastening security reliability of installation
Monolateral bolt.
Utility model content
The purpose of this utility model is to provide a kind of simple structure, easy to operate unilateral bolt fastener, to solve
The problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme：
A kind of unilateral bolt fastener, including bolt, nut, pad, plate and Long Circle termination, one end of the bolt
It is fixedly connected Long Circle termination, and the other end threaded coupling nut of bolt, and on the bolt between Long Circle termination and nut
Activity arranges pad；The other end end of the screw rod is integrally formed with hexagonal prism, and the end of prism offers bar shaped
Groove, the major axis for being oriented parallel to Long Circle termination of strip groove.
As further program of the utility model：The circle with screw rod is connect in the hexagonal cross-section of the hexagonal prism
Shape cross section.
As further program of the utility model：Diameter of the through-hole diameter at the pad center more than bolt.
As further program of the utility model：The minor axis length of the Long Circle termination is straight more than or equal to bolt
Footpath.
As further program of the utility model：The Long Circle termination and nut are respectively positioned at plate to be fixed
The consistent bolt mouth of Long Circle tip shapes is arranged on two ends, and plate, and pad is located between nut and plate outer surface.
As further program of the utility model：Long axial length of the long axis length of the Long Circle termination less than bolt mouth
Spend and more than the minor axis length of bolt mouth, the minor axis length of Long Circle bolt is less than the minor axis length of bolt mouth.
Compared with prior art, the beneficial effects of the utility model are：The installation of this practicality is more easy, and fastening effect can
Lean on, can complete without special tool(s).Side operation is only needed when using in addition, bolt tightening operation just can be completed.Solve
Bolt under some special operation conditions is installed.Among can be applicable to practice of construction, using effect is good.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of bolt.
Fig. 3 is the structural representation of plate.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Fig. 1~3 are referred to, in this utility model embodiment, a kind of unilateral bolt fastener, including bolt 1, nut 2, pad
Piece 3, plate 4 and Long Circle termination 5, one end of the bolt 1 is integrally formed and connects Long Circle termination 5, and the other end of bolt 1
Threaded coupling nut 2, and activity arranges pad 3, the through hole at the center of pad 3 on the bolt 1 between Long Circle termination 5 and nut 2
With diameter greater than the diameter of bolt 1, so as to edged washer movement, and the pressure produced on nut 2 is shared.
The other end end of the screw rod 1 is integrally formed with hexagonal prism, and the end of prism offers strip groove,
The major axis for being oriented parallel to Long Circle termination 5 of strip groove, in order to monolateral fastening, the hexagonal cross-section of hexagonal prism
Inside connect the circular cross section with screw rod 1, it is ensured that nut 2 can be removed, convenient production.
Diameter of the minor axis length of the Long Circle termination 5 more than or equal to bolt 1.
The Long Circle termination 5 and nut 2 are arranged at oval respectively positioned at the two ends of plate 4 to be fixed on plate 4
The consistent bolt mouth of the shape of shape termination 5, and pad 3 is located between nut 2 and the outer surface of plate 4, and by pad 3 nut 2 is shared
The pressure that plate 4 is produced, it is to avoid cause the deformation of bolt mouth position on plate 4.
The long axis length of the Long Circle termination 5 is less than the long axis length of bolt mouth and more than the minor axis length of bolt mouth,
Minor axis length of the minor axis length of Long Circle bolt less than bolt mouth.
This utility model first inserts Long Circle termination 5 and bolt 1 from outside when fastening to steel structure member
In the Long Circle bolt mouth of steel structure connection plate 4, swivel bolt 1 after insertion is rotated by 90 ° Long Circle termination 5.Laterally
Bolt 1 is pulled, Long Circle termination 5 is against on the inwall of attaching plate elements 4.Solid shim 3 and nut 2 are installed in outside, one is used
Spanner clamping screw rod end standing screw, another spanner clamp nut.
