When the utility model uses, on the rotor spinning machine negative pressure wind locular wall square opening is set, front tension bar passes square opening, draw ring is positioned at outside the air compartment wall, pulley on the closure plate of air duct is installed in the chute on the control panel wing plate, and plate elongated slot cutting ferrule on one's body plays the spacing guide effect that control panel is moved in the guide and limit bar that is fixed on the air compartment wall.The pulling draw ring makes the reach of front tension bar and back stay, drives the control panel reach, and pulley slides in chute, realizes driving the closure plate rotation and the sealing and the unlatching of control air passage port, thereby realizes the conversion of air duct.Front tension bar draws and shifts out behind the air compartment wall manually with the front tension bar rotation, the side of front tension bar will with the air compartment wall square opening hole wall angle that staggers, the end face of front tension bar is resisted against the air compartment wall and carries out axial location, prevents to move behind front tension bar and the back stay.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
The end face that described front tension bar is provided with installing hole is provided with stopper slot, and described back stay is provided with erection column one end and is provided with the spacer pin corresponding with stopper slot, and spacer pin is plugged in stopper slot, and the rotation of front tension bar is played position-limiting action.
Stopper slot on the described front tension bar end face is a circular arc, and the center of circle angle of circular arc is 60 degree, and the restriction front tension bar can only rotate 60 degree.
Described control panel plate body front end is provided with screw, and an end that is connected with control panel on the described back stay is provided with screw rod, and screw rod is installed in the screw, and is fastening with nut check, and back stay is fixedlyed connected with control panel.
The pin-and-hole quantity of described front tension bar side is two, and plane, two pin-and-hole center line places is vertical with the center line of installing hole, the spacing of two pin-and-hole center lines be slightly larger than annular groove base diameter on the back stay erection column and pin diameter and.
Use the utility model can reach following beneficial effect: because front tension bar and back stay cross section are square, front tension bar and back stay can manually not caused rotation in drawing process, can effectively avoid the generation of fault, and it is flexible and convenient to use, be resisted against the air compartment wall by the front tension bar end face and carry out axial location, make positioning stablity firm.
