Abstract
The utility model provides a fan-shaped fastener, which comprises a threaded body and a threaded hole formed in the threaded body, wherein the threaded body comprises an inner ring and an outer ring boss formed on the top end face of the inner ring; the cross section of the inner ring has a circular structure; the cross section of the outer ring boss has a fan-shaped structure. Due to the adoption of the fan-shaped fastener, a fastening effect is achieved, the occupied area of the fastener is reduced, and the economic benefit is increased; the fan-shaped fastener is simple in structure, and is convenient to manufacture.
Description
Technical field
The utility model is specifically related to fan-shaped fastening piece.
Background technique
Nuts and bolt is general fastening piece, also be all a kind of elements of manufacturing the necessary usefulness of machinery, the part that machinery is closely coupled together, equal specification nut and screw, just can link together, when use some special applications, need cooperate the smaller nut of occupation area as the less electronic product of volume ratio own, and adopt common nut to fix, or be easy to after fastening unclamp, but on the other hand, can guarantee that good fastening effect also is the comparison difficulty under the smaller situation of area.
Summary of the invention
Technical problem to be solved in the utility model is to provide fan-shaped fastening piece, can guarantee fastening effect, can reduce the occupation area of fastening piece again, and is simple in structure, easily manufactured, increases economic efficiency.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: fan-shaped fastening piece, comprise the screw thread body, be located at the intrinsic tapped hole of screw thread, the outer shroud boss of ring top end face in encircling in described screw thread body comprises and being located at, the ring cross section adopts round structure in described, and described outer shroud boss cross section adopts sector structure.
As preferably, described in the center of circle of ring and outer shroud boss on the central axis of screw thread body, ring and the center of circle of outer shroud boss are on same axis in this structure, structure is more reasonable, and is easily manufactured.
As preferably, the end of described tapped hole is provided with interior Hole chamfering, and the interior Hole chamfering of the end of this structure tapped hole is convenient to cooperating of tapped hole and miscellaneous part, has reduced the wearing and tearing of tapped hole end simultaneously.
As preferably, the fan-shaped angle of described outer shroud boss cross section is between 40 ° to 50 °, and the fan-shaped angle of this structure outer shroud boss is between 40 ° to 50 °, and structure is more reasonable, and is easily manufactured, and cost is lower.
Beneficial effect:
The utility model adopts technique scheme that fan-shaped fastening piece is provided, and has namely guaranteed fastening effect, has reduced the occupation area of fastening piece again, and is simple in structure, easily manufactured, improved economic benefit.
