Abstract

The invention discloses a door body opening and closing device driven by double sliding sleeves. The door body opening and closing device driven by double sliding sleeves comprises a shell, wherein a door pushing device and a driving device are arranged in the shell, the door pushing device is connected to the driving device through a swing piece and pushes a door body to rotate, the driving device comprises a first sleeve rod and a second sleeve rod which are arranged in parallel, the first sleeve rod slides in the axial direction of the shell and is sleeved with a first spring and a first sliding sleeve, the second sleeve rod is sleeved with a second spring and a second sliding sleeve, the swing piece pushes the first sliding sleeve to compress the first spring and pushes the second sliding sleeve to compress the second spring, the first sliding sleeve and the second sliding sleeve are in sliding fit and jointly form a sliding sleeve cavity, and a cavity spring is arranged in the sliding sleeve cavity. According to the door body opening and closing device, the driving device adopts a double-sliding-sleeve design, the damping adjustability in the door body opening and closing process is improved, the first sliding sleeve and the second sliding sleeve are in sliding fit, the acting force between the first sliding sleeve and the second sliding sleeve is transmitted through the cavity spring, and flexible connection of the first sliding sleeve and the second sliding sleeve is achieved.

Description

technical field [0001] The invention belongs to the field of furniture hardware fittings, and in particular relates to a door body switch driven by double sliding sleeves. Background technique [0002] Chinese patent document CN10976376 A discloses a door opener, which includes a housing composed of an upper cover plate and a lower cover plate. The driving device is driven to rotate, and the other end of the driving device is provided with a locking release device matched with the driving device. [0003] Although this solution makes the opening and closing of the swing door more convenient, the driving device only uses a sliding sleeve to act on the first spring and the second spring at the same time, and the damping during the opening and closing process of the door body can be adjusted relatively low, which is not conducive to improving the use of users. experience. For this reason, it is necessary to optimize the door body shutter. Contents of the invention [0004]...
