1. null1. a push-pull device at fixed with closed guide rail and the intrusion of resist printing thing,

  • Including rail guide piece (7) and the pull-push piece (9) that can be slided by push-pull effort in the guide groove of described rail guide piece (7),

    Described rail guide piece (7) includes main part (79) and is fixedly installed on the band roller box (71) at described main part (79) two ends,

    Guide groove is closed belt (8) and is held the belt wheel (711) being arranged in each described band roller box (71) respectively,

    Described guide groove close belt (8) upper portion in the upside slit (702) of described guide groove longitudinal extension thus described guide groove is closed,

    The lower portion of belt (8) longitudinal extension and be disposed through the through hole (90) at described pull-push piece (9) bottom in the underside cavity (701) of described guide groove closed by described guide groove,

    The bottom of described pull-push piece (9) is narrowed on the longitudinal direction of described rail guide piece (7) thus is formed narrowed portion,

    And the protrusion location division (98) forming the underside cavity (701) being matched with described guide groove in the cross section being orthogonal on described longitudinal direction and the neck extension portion (99) of the upside slit (702) being matched with described guide groove,

    Described protrusion location division (98) bottom face is provided with the first roller (94),

    Described first roller (94) is provided with four and is directional wheel,

    Described first roller (94) is separately positioned on the right and left of described protrusion location division (98) bottom face with each two one group,

    Described first roller (94) rolls with described main part (79) interior diapire and is connected,

    Such that it is able to drive described pull-push piece (9) steadily to move,

    Reduce the mobile abrasion caused,

    Wherein,

    The upper portion of described guide groove closing belt (8) has two ends and is connected in order to fixing with respective unidirectional drive housing component (81) respectively,

    Each described unidirectional drive housing component (81) is provided with cavity (810) in order to be slidably matched with the head bulb (92) of the corresponding plunger portion (91) at the sides adjacent being fixedly installed on described narrowed portion,

    Between the sidewall of the close described narrowed portion of the most described head bulb (92) and described unidirectional drive housing component (81) formed active force composition surface and and the sidewall away from described narrowed portion of described unidirectional drive housing component (81) between formed space,

    Thus pulled described guide groove to close belt (8) by the described active force composition surface at corresponding unidirectional drive housing component (81) place when described pull-push piece (9) is by push-pull effort effect,

    Now,

    The described plunger portion (91) at another unidirectional drive housing component (81) place is in sliding mode the most relatively,

    Described head bulb (92) is equipped with the second roller (95) at two ends up and down,

    Described second roller (95) rolls with described unidirectional drive housing component (81) inwall in described cavity (810) and is connected,

    In order to reduce, described head bulb (92) and described unidirectional drive housing component (81) are the most mobile causes abrasion to described second roller (95),

    Reduce serviceability.
