Automatic screen door

Abstract

The invention relates to an automatic screen door made by utilizing electronic induction technology and mechanical & electrical technology. An installation frame of the automatic screen door is provided with an electronic induction controller, a mini-type direct-current motor, a worm, a worm wheel, a driving wheel, an installing wheel, a steel wire rope, a folding rod and a folding door yarn. When a person gets close to the automatic screen door, the electronic induction controller energizes the mini-type direction-current motor in a forward direction and the mini-type direction-current motor rotates the worm and the worm wheel in a forward direction and the driving wheel of the worm wheel rotates at the same moment. The driving wheel drives the steel wire rope to slide towards one side. The folding rod of the steel wire rope folds and the folding door yarn disposed on the bottom of the folding rod folds. And the automatic screen door opens. When a person leaves the automatic screen door, the electronic induction controller energizes the mini-type direction-current motor in a reverse direction and the mini-type direction-current motor rotates the worm and the worm wheel in a reverse direction. The driving wheel drives the steel wire rope to slide towards the other side. The folding rod of the steel wire rope opens and the folding door yarn disposed on the bottom of the folding rod opens. And the automatic screen door closes.

Description

[0001] Technical field [0002] The invention relates to an automatic screen door, in particular to an automatic screen door made by using electronic induction device and electromechanical transmission technology. Background technique [0003] At present, the electronic induction automatic door technology is mature and widely used, but the anti-mosquito screen door is still a traditional wooden screen door or a simple screen door with magnetic strips, and the effect is not ideal when used. Contents of the invention [0004] In order to overcome the unsatisfactory use effect of existing screen doors, the present invention provides an automatic screen door. The automatic screen door uses an electronic induction controller to energize a micro DC motor for forward rotation or reverse rotation, and the micro DC motor Install a worm, the worm meshes with the worm wheel, a coaxial transmission wheel is installed under the worm wheel, the transmission wheel drives a transmission wir...
