Abstract
The invention relates to a fastener, in particular to an anti-falling fastener, and belongs to the technical field of connecting parts. The anti-falling fastener comprises two independent connecting portions. The anti-falling fastener is characterized in that the connecting portions comprise a main connecting portion and an auxiliary connecting portion; the main connecting portion is provided with limiting holes and locking holes formed in the positions, perpendicular to the limiting holes, of the connecting portion; the auxiliary connecting portion is provided with limiting protrusions matched with the limiting holes, and clamping holes corresponding to the locking holes are formed in the limiting protrusions; the limiting protrusions are inserted into the limiting holes, and locking bolts are further included; and the locking bolts are sequentially and tightly screwed in the locking holes and the clamping holes, and the main connecting portion and the auxiliary connecting portion are connected in a fastened manner. The height of the limiting protrusions is equal to or smaller than the depth of the limiting holes. The anti-falling fastener is reasonable and simple in structure, easy to produce and manufacture and convenient to use; through the anti-falling fastener, an existing fastener is improved, sliding of the connecting portions is avoided, and through the anti-falling fastener, the fastener is safer.
Description
Technical field
The present invention relates to a kind of fastening piece, specifically a kind of loose-preventing fastening, belong to link technical field.
Background technique
Fastening piece is a kind of link, is widely used in a lot of field; Existing fastening piece generally comprises two discrete joints, and two joints are bolted fixing.But in some particular surroundingss, as vibrated more place, the bolt of fastening piece easily gets loose, thus sliding easily appears in two joints, brings very large potential safety hazard.
Summary of the invention
The object of the invention is to solve the problem, provide a kind of rational in infrastructure simple, manufacture easy, easy to use, avoid joint to slide, the fastening piece of safety.
The present invention is achieved in that a kind of loose-preventing fastening, comprises two discrete joints, it is characterized in that: described joint comprises main joint and time joint; Described main joint is provided with the locking hole of spacing hole, the joint position vertical with spacing hole; Described time joint is provided with the spacing preiection mated with spacing hole, and spacing preiection is provided with the hole clipping corresponding with locking hole;
Described spacing preiection inserts in spacing hole, further comprises lock bolt, and lock bolt is tightened in locking hole, hole clipping successively, and main joint and time joint are fastenedly connected.
The height of described spacing preiection is equal to or less than the degree of depth of spacing hole.
The present invention rational in infrastructure simple, manufacture easy, easy to use, by the present invention, to the improvement that existing fastening piece carries out, specifically joint comprises main joint and time joint; Main joint is provided with the locking hole of spacing hole, the joint position vertical with spacing hole; Secondary joint is provided with the spacing preiection mated with spacing hole, spacing preiection is provided with the hole clipping corresponding with locking hole; Spacing preiection inserts in spacing hole, also comprises lock bolt, and lock bolt is tightened in locking hole, hole clipping successively, and main joint and time joint are fastenedly connected.By such mode, play and strengthen fixing effect, be mainly manifested in, spacing hole is inserted at spacing preiection, can play the effect of main joint and time joint settling position, when concrete enforcement, the height of spacing preiection is equal to or less than the degree of depth of spacing hole, thus make winner's joint more stable with time joint, effectively prevent the slip of main joint and time joint.In addition, in the present invention, further comprises lock bolt, lock bolt is tightened in locking hole, hole clipping successively, be tightened in locking hole, hole clipping successively by lock bolt, effectively can prevent loosening of fastening piece, screw successively to be connected on tapped through hole, tapped hole with bolt and match, ensure the fastening of fastening piece.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is spacing preiection structural representation of the present invention.
In figure: the main joint of 1 joint, 1-1,1-2 joint, 1-3 locking hole, 1-4 spacing preiection, 1-5 hole clipping, 2 lock bolts.
