Considering the shell structure and the fixed stability of pretightning force round pin formula mechanism, two first spouts can reach better effect, and first spout can reach the purpose of adjusting pretightning force round pin formula mechanism position, and the control range is: the screw rod drives the pre-tightening force pin type device to rotate by 150 degrees along the arc groove, namely, the pre-tightening force pin type device rotates by 150 degrees from vertical direction to downward direction in a counterclockwise mode, and the large round hole between the two first sliding grooves is used for reducing weight. The L-shaped fixing plate is used for fixing the steering engine, and corresponding punching schemes can be adopted according to different types of steering engines. And after the adjustment is finished, the nut is screwed down to fix the screw.
Anti-winding: the vertical pressure of exerting of pretightning force to parafoil control rope spanwise to along with parafoil control rope release's process, this power is in elastic pressure, can paste the parafoil control rope constantly, effectively reduces the winding possibility of knoing. It is adjustable: the size of pretightning force can be realized through the scope that removes pin control compression spring according to different actual conditions, and the position of pretightning force round pin formula mechanism can be adjusted to the regulating plate in addition to adapt to different play rope directions. On the basis of adjustment, the winding possibility of the control rope of the parafoil is greatly reduced through a pre-tightening pin type mechanism, and the safety of the parafoil system is guaranteed.
In addition, the invention also provides a parafoil, which comprises the parafoil control rope anti-winding device.
The technical scheme adopted by the invention has the beneficial effects that: through the pretightening force of the pretightening force pin type mechanism, the parafoil control rope is always pressed by the vertical parafoil control rope in the releasing or recovering process, so that the parafoil control rope is prevented from being wound and knotted on a winch, and the parafoil is convenient to control.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
