Abstract
The invention relates to a fastener and belongs to the technical field of connecting pieces. The fastener comprises two separate connecting parts which are fixedly connected through bolts. The fastener is characterized in that the connecting parts comprise the main connecting part and the secondary connecting part; the main connecting part is provided with threaded through holes and limiting holes, and the secondary connecting part is provided with threaded holes and limiting protrusions matched with the limiting holes; the limiting protrusions are inserted in the limiting holes, the bolts are sequentially screwed and connected to the threaded through holes and the threaded holes, and thus the main connecting part and the secondary connecting part are connected in a fastened mode. The threaded holes are threaded blind holes or threaded through holes. The height of the limiting protrusions is equal to or smaller than the depth of the limiting holes. The fastener is reasonable and simple in structure, easy to manufacture and convenient to use. According to the fastener, an existing fastener is improved, so that the connecting parts are prevented from sliding, and a safety function is also achieved.
Description
Technical field
The present invention relates to a kind of fastening piece, 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 fastening piece, and comprise two discrete joints, two joints are bolted fixing, it is characterized in that: described joint comprises main joint and time joint; Described main joint is provided with tapped through hole, spacing hole, the spacing preiection that described joint is provided with tapped hole, mates with spacing hole; Described spacing preiection inserts in spacing hole, and bolt screws successively and is connected on tapped through hole, tapped hole, and main joint and time joint are fastenedly connected.
Described tapped hole is tapped blind hole or tapped through hole.
The height of described spacing preiection is equal to or less than the degree of depth of spacing hole.
Described bolt be longer than the hole depth sum that the hole depth being more than or equal to tapped through hole adds tapped hole.
Described main joint is provided with 2-4 spacing hole.
Described time joint is provided with spacing hole same number and the spacing preiection mated with 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 arranges tapped through hole, spacing hole, the spacing preiection secondary joint arranges tapped hole, mating with spacing hole; Spacing preiection inserts in spacing hole, and bolt screws successively and is connected on tapped through hole, tapped hole, 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, the effect of main joint and time joint settling position can be played, when concrete enforcement, can be further, main joint is provided with 2-4 spacing hole, meanwhile, secondary joint is arranged the spacing preiection mated with spacing hole same number and with spacing hole, 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.Simultaneously, in the present invention, bolt screws successively and is connected on tapped through hole, tapped hole, more preferably, tapped hole is tapped blind hole or tapped through hole, and be also preferably, bolt be longer than the hole depth sum that the hole depth being more than or equal to tapped through hole adds tapped hole, these all make bolton better effects if.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the decomposition texture schematic diagram of Fig. 1.
In figure: the main joint of 1 joint, 1-1,1-2 joint, 1-3 tapped hole, 1-4 spacing preiection, 2 bolts.
Embodiment
Illustrate that the present invention is described further below in conjunction with accompanying drawing and accompanying drawing.
Embodiment 1
A kind of fastening piece, comprise two discrete joint 1, two joints 1 and be connected and fixed by bolt 2, in the present invention, joint 1 comprises main joint 1-1 and time joint 1-2; Main joint 1-1 arranges tapped through hole, 2 spacing holes, 2 the spacing preiection 1-4 secondary joint 1-2 arranges tapped hole 1-3, mating with spacing hole, wherein, tapped hole 1-3 is tapped blind hole; Insert in spacing hole by spacing preiection 1-4, bolt 2 screws successively and is connected on tapped through hole, tapped hole 1-3, thus makes, and main joint 1-1 and time joint 1-2 is fastenedly connected.
Further, in the present invention, the height of spacing preiection 1-4 equals the degree of depth of spacing hole.Bolt 2 be longer than the hole depth sum that the hole depth being greater than tapped through hole adds tapped hole 1-3.
Embodiment 2
A kind of fastening piece, comprise two discrete joint 1, two joints 1 and be connected and fixed by bolt 2, in the present invention, joint 1 comprises main joint 1-1 and time joint 1-2; Main joint 1-1 arranges tapped through hole, 3 spacing holes, 3 the spacing preiection 1-4 secondary joint 1-2 arranges tapped hole 1-3, mating with spacing hole, wherein, tapped hole 1-3 is tapped blind hole; Insert in spacing hole by spacing preiection 1-4, bolt 2 screws successively and is connected on tapped through hole, tapped hole 1-3, thus makes, and main joint 1-1 and time joint 1-2 is fastenedly connected.
Further, in the present invention, the height of spacing preiection 1-4 is less than the degree of depth of spacing hole.Bolt 2 be longer than the hole depth sum that the hole depth equaling tapped through hole adds tapped hole 1-3.
