Multifunctional sliding door device

Abstract

The invention discloses a multifunctional sliding door device which comprises at least one sliding door, a door frame and a lock catch structure. The sliding doors are movably arranged on the door frame. The lock catch structure comprises locking pieces and a buckling piece. The locking pieces are arranged on the sliding doors and comprise handles, and the buckling piece is arranged on the door frame. Each sliding door comprises a plurality of pressing wheels, and the pressing wheels are arranged on each sliding door. The door frame comprises a pair of guide rails, a plurality of pressing pieces and a plurality of sealing pieces. The guide rails are fixed to the door frame, the sealing pieces are fixed to the door frame, and the pressing pieces are fixed to the guide rails and provided with inclined faces. When the sliding doors are closed, the sliding doors are pushed to make the pressing wheels move along the guide rails and move to the highest ends of the inclined faces from the lowest ends of the inclined faces, so that the door edges of the sliding doors press the sealing pieces, and meanwhile the handles are rotated to lock the locking pieces to the buckling piece so as to lock the sliding doors to the door frame; when the sliding doors are opened, the handles are rotated reversely to separate the locking pieces from the buckling piece, and the sliding doors are pushed so that the pressing wheels can move along the guide rails to open the sliding doors.

Description

technical field [0001] The invention relates to a multifunctional sliding door device. Background technique [0002] In modern buildings, for the sake of ventilation, lighting and aesthetics, a multi-functional sliding door device is usually designed at the junction of the balcony and the hall. In order to obtain the ideal effect of protecting the indoor environment, the sliding door device is required to have better sound insulation and Waterproof function, so people have designed various sliding door devices. Most of the sliding door devices on the market currently have the door leaf fixed in the sliding door, the door frame is fixedly connected to the wall and cannot be moved, and the sliding door and the door frame are installed together to slide in the track of the door frame. In order to achieve the sealing effect, people usually install sealing burrs or rubber strips at the contact between the sliding door and the door frame to block air and water. But between the s...

AI Technical Summary

Problems solved by technology

But between the sliding door and the door frame, there is no compression structure for pressing the sealing burrs or rubber strips or no locking structure to prevent the sliding door from leaving the door frame, so that the sealing burrs or rubber strips do not completely seal the contact between the sliding door and the door frame. The multifunctional sliding door device is used in places with many typhoons or sandstorms, and the effects of waterproof, windproof, dustproof and sandproof are very poor, resulting in unsatisfactory sealing effect
