Single-power-source automatically opened, closed and locked double door controlled by crank-slider mechanism

Abstract

A single-power-source automatically opened, closed and locked double door controlled by a crank-slider mechanism is composed of a right door body, a first shaft, a first connection bridge, a first spring, a first fixed rod, a connecting rope, a fixed pulley, a first fixed disc, a second shaft, a second connection bridge, a second spring, a second fixed rod, a second fixed disc, a door frame, a first slider, a first hinge hole, a first guide rail, a first joint lever, a second hinge hole, a first connecting rod, a lever, a rotation shaft, a fixed block, an ejector rod, a second guide rail, a second slider, a second connecting rod, a left door body, a third hinge hole, a second joint lever, a third guide rail, a third slider and a fourth hinge hole. Compared with an existing double door, the single-power-source double door can achieve opening and closing of the door and a lock through automatic control, the operation is easier and more convenient when controlling is performed, the single-power-source double door can be opened and closed both inwards and outwards, and therefore the theftproof performance is better; meanwhile, the single-power-source double door can be made of materials such as wood, metal and glass, and therefore the door has the advantages of low cost, aesthetic property, practicability and safety.

Description

technical field [0001] The invention relates to an automatic opening and locking double-leaf door, in particular to a single-action source automatic opening and locking double-leaf door controlled by a crank slider mechanism.
