The blocking mechanism of existing design has been accomplished door leaf tapered end all around with a cover blocking mechanism and has been locked simultaneously.Not only shortened the door leaf shut-in time but also practiced thrift raw material, operated simple again.
Operating principle:
To pressing down handle, the longitudinal rod that is assemblied on the handle moves downward, with the upper and lower small rod of left longitudinal rod assembling; Pivoted arm drives upper and lower tranverse connecting rod, does transverse movement; Be assemblied in the following small rod of lower transverse connecting rod; Pivoted arm drives right longitudinal rod and makes the tapered end that upper and lower motion drives around the door leaf simultaneously and insert the doorframe lockhole, fastens door leaf.Upwards handle is then opened door leaf.
As preferably, vertical junction plate in a described left side and third quadrant pivoted arm, a left side vertically junction plate and four-quadrant pivoted arm, lower link and first quartile pivoted arm are connected to a fixed through small rod respectively.
As preferably, described left side lock end and a left side vertically tapered end, the end of locking with last tapered end, lock end down and hold with the vertical tapered end in the right side with lower lock head, right lock and be skewed the connection respectively.
Therefore, the blocking mechanism that is used for the moistureproof sealed door of single fan of the utility model, simple in structure, easy to operate, long service life improves safety, saves material.
