Abstract

The utility model discloses a fastening piece which comprises a bolt and a bush, wherein the bush is connected to a screw rod of the bolt in a sleeved mode. At least two protruding points are arranged on the upper surface of the bush and located on the edge of the inner wall of the bush, and after the bush is locked, the protruding points can protrude out of the inner wall of the bush. The fastening piece solves the problem that in the prior art, a bush and a bolt can be separated easily, through the at least two protruding points which are arranged on the upper surface of the bush and close to the inner wall of the bush, after the bush is connected to the bolt in the sleeved mode, the bush is locked, the protruding points protrude out of the inner wall of the bush, the protruding points are used for limiting the bush, and separation of the bush and the bolt is avoided.

Description

A kind of fastening piece
Technical field
The utility model has related to a kind of fastening piece, belongs to the Machining Technology field.
Background technique
Fastening piece is widely used in connection and the application between the material of different qualities.In order to make the connection better effects if of fastening piece, usually on the screw rod of fastening piece, be set with lining, and this lining normally before fastening piece dispatches from the factory with regard to supporting being arranged on screw rod, so that the later stage is more convenient while using.But, for can being overlapped, lining installs on screw rod, usually the internal diameter of lining is designed to consistent with screw flight section width, and lining directly is sleeved on screw rod, this mounting type is in the transportation process of fastening piece, owing to jolting, rocking, be easy to make lining and screw rod to be separated, cause fastening piece in use, need to reselect suitable lining and be coordinated completely, cause installation efficiency low.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of fastening piece, can effectively avoid separating of sleeve pipe and bolt, is convenient to the installation of fastening piece, has improved installation efficiency.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of fastening piece comprises bolt and is socketed in the lining on the screw rod of described bolt that it is characterized in that: the upper surface of described lining is provided with at least two salient points near its inner wall edge place, and described lining is after locking, and salient point can protrude from the inwall of described lining.
Aforesaid a kind of fastening piece is characterized in that: the quantity of described salient point is two, is located at respectively the two ends of any diameter of described lining inwall.
Aforesaid a kind of fastening piece is characterized in that: the quantity of described salient point is four, equidistantly is distributed on the contour of described lining inwall top.
Aforesaid a kind of fastening piece is characterized in that: the quantity of described salient point is three, equidistantly is distributed on the contour of described lining inwall top.
Aforesaid described a kind of fastening piece, it is characterized in that: the quantity of described salient point is three, is on the contour that the isosceles rectangular shaped is distributed in described lining inwall top.
The beneficial effects of the utility model are: by the upper surface at lining, near its inwall place, at least two salient points are set, after the lining cover is received on bolt, lining is locked, make the inwall of salient point protrusion and lining, the salient point utilize protruded carries out spacing to lining, avoid separating of lining and bolt.

Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of fastening piece, comprise bolt 2 and be socketed in the lining 1 on the screw rod 21 of described bolt 2, the upper surface of described lining 1 is provided with at least two salient points 11, described salient point 11 is positioned at the inner wall edge of described lining 1, and described lining 1 is after locking, and salient point 11 protrudes from the inwall of described lining 1, the salient point that utilizes the screw section 22 of screw rod 21 and protrude carries out spacing to lining 1, avoid separating of lining 1 and bolt 2.
The first embodiment
As Figure 2-Figure 5, the quantity of salient point 11 is two, is located at respectively the two ends of any diameter of described lining 1 inwall, when lining 1 after locking, salient point 11 protrudes from the inwall of described lining 1, by the salient point protruded, lining 1 is carried out spacingly, avoids separating of lining 1 and bolt 2.
The second embodiment
As shown in Fig. 6-Fig. 9, the quantity of salient point 11 is four, equidistantly be distributed on the contour of described lining 1 inwall top, when lining 1, after locking, salient point 11 protrudes from the inwall of described lining 1, by the salient point protruded, lining 1 is carried out spacingly, avoid separating of lining 1 and bolt 2.
The 3rd embodiment
As shown in Figure 10 and Figure 11, the quantity of salient point 11 is three, equidistantly is distributed on the contour of described lining 1 inwall top, when lining 1 after locking, salient point 11 protrudes from the inwall of described lining 1, by the salient point protruded, lining 1 is carried out spacingly, avoids separating of lining 1 and bolt 2.
The 4th embodiment
As shown in Figure 12 and Figure 13, the quantity of salient point 11 is three, be on the top contour that the isosceles rectangular shaped is distributed in described lining 1 inwall, when lining 1 after locking, salient point 11 protrudes from the inwall of described lining 1, by the salient point protruded, lining 1 is carried out spacingly, avoid separating of lining 1 and bolt 2.
