| 摘要 |
The present invention relates to an adjustable large-sized advertisement curtain wind-resistant module, which includes a base, the slidable board, a coupler, a transmission device, and a transmission rod. The base has a screw rod. The slidable board has a surface slidably mounted to the base and coupled with the screw rod and an opposite surface to which the coupler is mounted for coupling with the frame. The transmission device is arranged in the base and coupled to the screw rod. The transmission rod drives the transmission device and the transmission device in turn drives the screw rod, so that the screw rod may drive the slidable board to do linear displacement on the base. The linear displacement of the slidable board in opposite directions carries the frame to be moved in unison therewith to achieve adjustment of distance between two frames for stretching flat an advertisement curtain between the frames. |

1. An adjustable large-sized advertisement curtain wind-resistant module, which is adapted to support a frame of an advertisement curtain, comprising:
a base, which has two sides forming first slide rails opposing each other and comprises a screw rod, the screw rod having an end forming a first connection section and an opposite end forming a second connection section, the screw rod receiving at least one nut fit thereto and mating therewith so that the nut is linearly movable along the screw rod; a slidable board, which is coupled to the base and has a first surface and a second surface, the slidable board comprising opposite second slide rails respectively formed on opposite side edges of the first surface, the second slide rails being respectively engageable with the first slide rails of the base in a relatively slidable manner, the slidable board comprising a third slide rail formed on the first surface between the second slide rails and a cushioning device received in the third slide rail, the cushioning device being coupled to the nut of the base; a coupler, which is mounted to the second surface of the slidable board, the coupler comprising at least one coupling section; a transmission device, which is mounted to the base and comprises:
a seat, which comprises two opposite first through hole and a second through hole, the two first through holes being arranged along an axis that is in a direction different from an axis on which the second through hole is located, the second through hole corresponding to the first connection section of the screw rod,a transmission gear train, which is mounted in the seat and arranged in an axis coincident with the axis of the two first through holes, anda toothed wheel, which is arranged in the seat and mates the transmission gear train, the toothed wheel being set on an axis coincident with the axis of the second through hole and set at the location of the second through hole, the toothed wheel being coupled to the first connection section of the screw rod; and a transmission rod assembly, which comprises a rod received in the two first through holes of the seat and is coupled to the transmission gear train. |
