VINYL TRACTION FOR WORKBENCH

摘要

PURPOSE: A workbench for pulling a vinyl film is provided to cover a plastic greenhouse frame with a vinyl film conveniently in a short period of time with needing to blow the vinyl film. CONSTITUTION: A front fixture(10) is hook-fixed to a front upper part of a plastic greenhouse frame. A rear fixture(20) is hook-fixed to a rear upper part of the plastic greenhouse frame. A vinyl film traction part(30) pulls a vinyl film from the front upper part to the rear upper part of the plastic greenhouse frame. A side horizontal connecting bar(230) connects a first rear vertical fixture(210) and a second rear vertical fixture(220). A fixing member(240) fixes the vinyl film traction to the first and second rear vertical fixtures. A hook fixing member(250) is hook-fixed to the rear upper part of the plastic greenhouse frame. Fixing plates(241) are separately fixed to the first and second rear vertical fixtures. A accepting member(242) accepts the upper part and the lower part of vinyl film traction part respectively. A projection plate(243) is protruded toward the front direction of the fixing plate on the front surface of the fixing plate. The rear part of a link member(244) is axis-combined to the upper part of the projection plate. A rotary member(245) prevents the vinyl film traction part kept in the accepting member from separating from the accepting member. A handle member(2456) moves the lower part of the rotary member up and down in a rotary manner. The vinyl film traction part comprises a geared motor(310) and a drum part(320). The geared motor is formed with a supporting rod(330) which is extended at a certain length from side to side in the lower part.
