Description

The automatic door moving machine of screw

The utility model relates to the door moving machine that slide door or window is closed automatically, is particularly suitable for installing and using on aluminium alloys, steel casement door and the wooden door in the private residence.

Relate in the building construction, door and window is important composition department.Come in and go out frequent place and special tectonic (as elevator etc.) of (as hotel, financial institution, airport etc.) crowd gone up automatic door is installed in top-grade building at present.Automatic door is not only neatly refined, is convenient to house-owner, guest; And in time open and close,, can keep the temperature difference stable especially in the air conditioning chamber.But various drawbacks such as existing automatic door exists assembling complicated, and the price eighteenth of the twenty is expensive are not suitable for that family installs and uses in the private residence.

The purpose of this utility model be design a kind of with motor by screw drive, be equipped with contact and remote control switch, realize closing automatically the door moving machine with door and window, be particularly suitable for private residence and use.

The technical scheme of the automatic door moving machine of the utility model screw is: by frame, the motor of installing on the frame, screw rod and electric switch, clutch etc. are formed, its so-called clutch has electromagnet, inhale under the iron pressure head is arranged, pressing plate is installed on frame, contact with pressure head above the pressing plate, match with guide pillar below the pressing plate, guide pillar has spring, junction plate and pulley outward, the fixed end of junction plate is installed on the door, pulley matches with the chute of slide plate, matches with screw flight in the lower end of guide pillar.

The automatic door moving machine of screw of the present utility model is installed travel switch at two of machine, when the screw conveyer clutch to two, travel switch control is inhaled iron and is cut off the electricity supply, and makes the disengagement of guide pillar and screw thread.And the moving relay of control motor forward and backward revolution is installed is cut bit switch.

The automatic door moving machine of screw of the present utility model in order to ensure safety, is installed transformer on power circuit, input voltage 220V, and the transformer transformation is 24V or below the 24V, the best is 12V.

The automatic door moving machine of screw of the present utility model in order to reach automatically, is installed the blanket type foot switch at the import and export of door.Foot switch can adopt such structure, upper and lower have an insulating carpet, there are conductive plate, resistance guide plate, conductive plate in the centre, hinder the hole that conducts electricity on the guide plate, the resistance guide plate is made by insulation materials two conductive plates is separated, so no power, and after the people sets foot on carpet, the resistance guide plate is compressed, and two conductive plates play on-off action by the hole conducting that conducts electricity.

The utility model discloses the automatic door moving machine of a kind of screw, compared with the prior art, have simple structure, with compositions such as sheet metal, plastics and ordinary appliances switches; Function is many, can reach automatically foot-operated, and it is semi-automatic that hand is pressed switch, remote control and manual (during power failure); Characteristics such as installation, maintenance is convenient.
