The pull rod type air door opening mechanism comprises an air door pipe, the left side of the outer ring surface of the air door pipe is fixedly sleeved with a left connecting ring plate, and the left side of the outer ring surface of the air door pipe is fixedly sleeved with a right connecting ring plate; a binding sleeve is fixedly connected to the surface of the bottom of the air door pipe from left to right, a first supporting sleeve and a second supporting sleeve are fixedly embedded in the surface of the bottom of the air door pipe in sequence, a sector gear and a rotating gear are movably embedded in inner cavities of the first supporting sleeve and the second supporting sleeve through bearings correspondingly, and a sliding rail is arranged in an inner cavity of the binding sleeve in a penetrating mode. The telescopic rod, the pressing block, the telescopic column, a second supporting sleeve, a sector gear, a sliding rail, a binding sleeve, a toothed plate, a rotating gear, a first supporting sleeve and a positioning threaded sleeve are used in cooperation, the advantage that the air door is closed in a gear transmission mode is achieved, in the actual air door closing process, precision is high, movement is smoother, and use is more convenient. And the conditions of movement vacancy and abnormal sound are avoided, and closing of the air door is facilitated.
本发明公开了一种拉杆式风门开启机构,包括风门管,所述风门管外圈表面的左侧固定套设有左连接圈板,所述风门管外圈表面的左侧固定套设有右连接圈板,所述风门管底部的表面从左至右依次固定连接有束缚套、固定镶嵌有第一支撑套和第二支撑套,第一支撑套和第二支撑套的内腔通过轴承分别活动镶嵌有扇形齿轮和旋转齿轮,束缚套的内腔贯穿设置有滑轨。本发明通过伸缩杆、压块、伸缩柱、第二支撑套、扇形齿轮、滑轨、束缚套、齿板、旋转齿轮、第一支撑套和定位螺套配合使用,具有采用齿轮传动的方式关闭风门的优点,在实际关闭风门的过程中,精度高且运动更加顺畅,不会出现运动虚位以及异响的情况,有利于风门的关闭。
