Two-way opening and closing door

Abstract

The invention discloses a two-way opening and closing door. The two-way opening and closing door comprises a door leaf and a door frame, wherein hinge seats are separately arranged at four corners ofthe door leaf, and hinge shafts matched with the hinge seats are correspondingly arranged at the corresponding positions on the door frame; anti-off limiting shafts are arranged on the hinge shafts, and hinge shaft grooves matched with the hinge shafts are formed in the side walls of the hinged ends of the corresponding hinge seats; the hinge shafts are mounted in the hinge shaft grooves in a clamped mode, and anti-off limiting shaft grooves matched with the anti-off limiting shafts are formed in the positions, corresponding to the anti-off limiting shafts, on the end surfaces of the hinged ends of the hinge seats; the anti-off limiting shaft grooves communicate with the hinge shaft grooves, and the hinge seats are internally provided with limiting pins with return springs; the head partsof the limiting pins extend into the hinge shaft grooves and limit the hinge shafts in the hinge shaft grooves; and when the hinge seats and the corresponding hinge shafts are in a closed state, the anti-off limiting shafts are located in the corresponding hinge shaft grooves, and when the hinge seats and the corresponding hinge shafts are in an open state, the anti-off limiting shafts are clampedin the corresponding anti-off limiting shaft grooves. The two-way opening and closing door is suitable for all kinds of doors and windows.

Description

technical field [0001] The invention relates to the field of mechanical hinges, in particular to a two-way opening and closing door. Background technique [0002] A mechanical hinge is a mechanical device used to connect two solids and allow relative rotation between them. It is suitable for various doors and windows, such as windows, house doors, cabinet doors, electrical cabinet doors, etc. But the existing doors and windows that adopt this mechanical hinge generally can only be opened in one direction, and like this, cannot be applicable for the doors and windows with special opening requirements. Contents of the invention [0003] The object of the present invention is to provide a two-way opening and closing door in order to overcome the shortcomings of the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides a two-way opening and closing door, which includes a door leaf and a door frame. A hinge seat is...
