Tool 200, will not collide as the smoke barrier of fixed-axis rotation with higher cookware 200.
Because the forms of motion of smoke barrier 5 of the invention is the aggregate motion of translation with rotation, two sides are using sliding rail come real
Its existing translation will cause that sliding rail blocks or frictional force is larger if two wood side-guide discontinuity, therefore driving mechanism 61 is pacified
Loaded on centre, it can utmostly ensure two wood side-guide uniform forces.If driving mechanism 61 is placed in one side, smoke barrier 5 is transported
During dynamic, since 5 length of smoke barrier is longer, under the action ofs gravity etc., the movement of end and driven end is driven it is difficult to ensure that same
Step, driven end often fall behind and driving end.Because moving fairly simple, smoke barrier driving end and driven end in fixed-axis rotation
The asynchronous degree of movement can be smaller；But move in the present invention more complicated, for the aggregate motion for being translatable and rotating, use
When unilateral driving structure, this asynchronism can clearly, and can be clearly visible driven end in 5 opening procedure of smoke barrier can fall behind
In driving end, or even because asynchronous cause that sliding rail blocks or frictional force is larger.
