<p>An adjustable tensioning module for large-sized advertisement curtains including a base 1, a slidable board 2, a coupler 3, a transmission device 4, and a transmission rod 5. The base has a screw rod 13 and the slidable board is slidably mounted to the base via rails 12, 23 and coupled with the screw rod on the opposite surface to which the coupler is mounted. 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 for linear displacement along the base. The linear displacement of the slidable board provides adjustment of distance between two frames when stretching an advertisement curtain between the frames.</p> |
