An open mechanism driven vertically

Abstract

The utility model discloses a vertical drive's opening mechanism, is installed with a plurality of harness frame on loom, and each harness frame all transmission connection one harness lifting mechanism, arbitrary harness lifting mechanism includes two reciprocating drive mechanisms of interval setting on loom, and two reciprocating drive mechanisms respectively transmission connection has one connecting rod, and the free end of two connecting rods is hinged with harness frame respectively, and two reciprocating drive mechanisms and two connecting rods cooperation can make harness frame move up and down reciprocating in vertical direction, and arbitrary reciprocating drive mechanism still transmission connection has elastic tension member, and elastic tension member is connected with loom, and it is located the top of reciprocating drive mechanism, and the telescopic direction of elastic tension member is parallel with the reciprocating movement direction of harness frame. One side will install elastic tension member in the top of reciprocating drive mechanism, to facilitate installation, on the other hand, the setting of elastic tension member also is favorable to harness frame and moves from below to above, and reduces energy consumption.
