Description
Technical field
The utility model relates to the door opener field, specifically, relates to a kind of electric door opener.
Background technology
Existing door opener mainly is applicable to rolling door and vertical hinged door etc., and can not be used for the rotating open-close door and window, and these products adopt mechanical safety mostly.Shortcomings such as travel switch etc., structure are often very complicated, particularly exist volume big, and easy inefficacy and efficient are low.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, volume is little, good reliability, and can realize the electric door opener that turns to open.
The technical scheme that realizes above-mentioned purpose is: a kind of electric door opener, comprise motor, link assembly and the casing that is formed by fixedly connecting by upper box and lower box, motor is installed on the casing, also has small gear in the casing, worm screw, big worm gear and splined shaft, the output shaft of motor is a worm shaft, and mesh with small gear, small gear is sleeved on the worm screw and with worm screw fixedlys connected, worm screw and splined shaft all can be rotated to support in the casing, big worm gear set is contained on the splined shaft, and is connected with splined shaft by key, and big worm gear and worm engaging, splined shaft is connected with link assembly, and motor is connected with an intelligent controller by lead.
After adopting technique scheme, motor links to each other with an intelligent controller by lead, when door is held successfully or is shut, electric current in the lead can raise suddenly, and intelligent controller cuts off electric current immediately shuts down motor, thereby need not to adopt mechanical safety and travel switch, simplify the structure greatly, dwindle volume, improved efficient, and good reliability.Behind the motor rotation, the output shaft of motor drives the small gear rotation, small gear drives the worm screw of fixedlying connected with it and rotates, worm screw drives the big worm gear rotation with its engagement again, big worm gear drives splined shaft by key and rotates, the splined shaft rotation drives the link assembly that is connected with door, so can the rotating open-close door and window.
