Abstract:
A sliding door device, comprising a door body (1), a frame body (2) and a pulley assembly (3). The door body (1) slides by means of a first sliding rail (20) hung on the frame body (2) of the pulley assembly (3). The sliding door device further comprises a door opening and closing assembly which is arranged between the pulley assembly (3) and the frame body (2); the door opening and closing assembly (4) comprises a first swing rod (41), a second swing rod (42), a first elastic body (43), a second sliding rail (44), a connecting member (45) and a movable block (46); the first swing rod (41) and the second swing rod (42) are hinged by means of a rotating shaft (47) and arranged within the frame body (2), and the first swing rod (41) and the second swing rod (42) are arranged at a certain angle; the first elastic body (43) is arranged between the second sliding rail (44) and the second swing rod (42), one end of the first elastic body is fixed to the frame body (2), and the other end of the first elastic body acts on the bottom of the second swing rod (42), so that the second swing rod (42) and the second sliding rail (44) form a space for the movable block (46) to go through. The sliding door device achieves the automatic door closing effect of an existing electric sliding door by means of a mechanical device, and solves the problem that the operating force constantly exerted on an existing mechanical sliding door body is too large.
