Detailed Description
The present invention will be further described with reference to the accompanying drawings.
An elevator door hanging plate assembly is installed on an elevator door head and matched with a guide rail 2, and the elevator door head is provided with a left door hanging plate assembly 1 and a right door hanging plate assembly 1, so that relative motion of two elevator doors is realized.
As shown in fig. 2 and 3, door link plate subassembly 1 includes link plate body 11, two pulleys 14 and a spacing wheel 18, two pulleys 14 are established respectively the back upper portion both sides of link plate body 11, the distance is big more between two pulleys 14, door link plate subassembly 1 slides more stably, pulley 14 mainly plays the guide effect, during operation pulley 14 contacts the walking at the top of guide rail 2, therefore pulley 14 has bearing and rubber layer, link plate body 11 is last to correspond pulley 14 department and is equipped with circular mounting hole, pulley 14 is fixed in circular mounting hole department through pivot and nut cooperation, two pulleys 14 are bilateral symmetry and set up, two pulleys 14 keep same level after the installation, ensure that two pulleys 14 can both reliably contact with guide rail 2.
