Ship air vent with damper connected hand and reducer gear directly

摘要

The present invention provides a ventilation apparatus having a vessel handle integral series-connected reduction gear damper. Such a handle integral reducer vessel aeration device having a series-connecting the damper according to the invention is of a configuration to provide a structure which is fixed while the blade axis and series-connected via a reduction gear directly to the handle damper housing for manual operation of the damper blade simplified, has a reduction of production costs, improvement of the installation accuracy minimized, the installation assembly of the assembly and thus poor technical features that promote a stable use and durability of the device according to. It handles integrated speed reducer vessel aeration device having a series-connecting the damper according to the present invention comprises a damper housing (10) having a side wall 12 enclosing an interior space (11); The interior space a plurality of damper blades 20 are arranged in a set interval to the 11 of the damper housing (10); A plurality of damper blade 20 from any one of the damper blades 20 coupled with the blade axis of rotation (21a) formed on one end portion selected, the first reduction is rotated to the blade axis of rotation (21a) integral with the gear 30, Wow; And the damper housing 10 of side wall 12, handlebar 40 having a handle 41 to be fixed for rotation, one end of the; And the second reduction gear 50, which is formed on the other end of the handlebar 40, the first reduction gear 30 and engaged, such that the deceleration achieved to the first reduction gear 30; A plurality of damper blades 20, each blade shaft 21 is fixed, a plurality of link pieces (60) which rotates each blade shaft 21 and integrally formed on one end and; Including the plurality of link piece 60 bar which is fixed to the setting distance (bar) link bar 70 of shape, wherein the handlebar (40) during the rotation of the handlebar 40 by the handle 41 the second reduction gear 50 and the rotation is induced in the first reduction gear 30, the blade axis of rotation (21a), the first reduction gear 30 is formed jimyeonseo achieved deceleration between formed on the blade axis of rotation (21a), reduced rotation of the entire damper blade 20 by a plurality of link piece 60 and the link bar 70, which rotates integrally with the rotary shaft, each blade (21) will be derived. ;
