Description
Technical field
This utility model relates to hardware-joint field, particularly relates to a kind of square bolt of hay mover rotating vane.
Background technology
Gardens hay mover is with the flexible plastic strip of high speed rotating, grass to be cut off, and is commonly called as flail knife formula.Because plastic strip
Being flexible, also can fracture unlike metal fan blade just in case encountering on corner or stone, the plastic strip of hay mover is easy
Damaging part, replacement frequency is higher.So the square bolt of fixed plastic strip has particular/special requirement to bulk strength.Particularly with turn
The structure that leaf connects, easy accessibility to be considered.The attachment structure how using a kind of highly effective and safe is urgent problem.
Summary of the invention
In order to overcome the defect of prior art, this utility model provides a kind of square bolt of hay mover rotating vane.
This utility model solves its technical problem and be the technical scheme is that a kind of square bolt of hay mover rotating vane, bag
Include bolt body, circular arc projection, threaded portion and square plate, bolt body, circular arc projection, the axial line of threaded portion and square plate
Symmetrical centre is respectively provided with on the same line；
One end of described bolt body is axially connected to threaded portion, and the other end is axially arranged square plate；
On the four edges of described square plate, uniform the edge that is provided with is that the circular arc of arc-shaped is protruding；
The through hole installing hay mover plastic strip it is provided with on described threaded portion.
Beneficial effect
A kind of square bolt of hay mover rotating vane, bulk strength is high, uses the connection that square structure and circular arc projection combine
Structure is attached with hay mover rotating vane, convenient installation, and intensity is high.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
In figure: 1, bolt body；2, circular arc is protruding；3, threaded portion；4, square plate；5 through holes.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is expanded on further.
As it is shown in figure 1, a kind of square bolt of hay mover rotating vane, including bolt body 1, circular arc projection 2, threaded portion 3 and side
Shape plate 4, the symmetrical centre of bolt body 1, circular arc projection 3, the axial line of threaded portion 3 and square plate 4 is arranged at same straight line
On；
One end of described bolt body 1 is axially connected to threaded portion 3, and the other end is axially arranged square plate 4；
Uniform on the four edges of described square plate 4 it is provided with the circular arc projection 2 that edge is arc-shaped；
The through hole 5 installing hay mover plastic strip it is provided with on described threaded portion 3.
Bolt body 1 primarily serves the effect of a connection rotating shaft, and the when of connection, square plate 4 can be embedded into hay mover
In the square groove at rotating vane center, this square groove is provided with a circular hole, be able to accommodate circular arc projection 2 and be embedded in circular hole, then use
Circular hole is sealed and is achieved that and the connection of hay mover rotating vane by other end caps.
This utility model bulk strength is high, the attachment structure that employing square structure and arc combine and hay mover rotating vane
Being attached, convenient installation, intensity is high.
