Abstract

A sealing mechanism (100) for a push-pull device. The sealing device (100) comprises a first sash frame (1), a second sash frame (2), a control device (3), a first transmission device (4), a second transmission device (5), and a sealing device (6). The second sash frame (2) is horizontally disposed and two ends thereof are fixedly connected to two ends of the first sash frame (1), respectively. The control device (3) is fixedly connected to the first sash frame (1). The first transmission device (4) is provided in the first sash frame (1), and is transmittingly connected to the control device (3). The sealing device (6) is located at the bottom of the second sash frame (2). The second transmission device (5) comprises a lifting rod (51) and a plurality of springs (52). The lifting rod (51) is horizontally disposed in the second sash frame (2), the tops of both ends of the lifting rod (51) are fixedly connected to both ends of the first transmission device (4) respectively, and the bottom of the lifting rod (51) is fixedly connected to the sealing device (6). The tops of the plurality of springs (52) are all fixedly connected to the bottom of the first sash frame (1), and the bottoms of the plurality of springs (52) are all fixedly connected to the top of the lifting rod (51). The sealing mechanism (100) can be raised and lowered to fully seal the bottom of the device.

Abstract

A door (100) having a floor spring, comprising a door leaf (1) and a sealing device (2), the sealing device (2) comprising a first control mechanism (21), a first connecting rod (22), a first sealing material (23), a second control mechanism (24) and a second connecting rod (25); the first control mechanism (21) and the second control mechanism (24) are respectively located at the two ends of the top (11) of the door leaf (1), the first sealing material (23) is located at the bottom (14) of the door leaf (1), the first control mechanism (21) is in transmission connection with the first sealing material (23) by means of the first connecting rod (22), and the second control mechanism (24) is in transmission connection with the first sealing material (23) by means of the second connecting rod (25). With the closing and opening of the door leaf (1), the control mechanism transmits and controls the first sealing material (23) to stretch out for sealing and to return to the original position. The sealing device (2) of the floor (100) having a spring door is precise and flexible and has a good sealing performance, effectively solving the sealing problem of wind and water entering from the bottom (14) of the door leaf (1) of the floor spring door (100).
