Door with buffer effect

Abstract

The invention discloses a door with a buffer effect. The door comprises a rotating shaft and a door body, the door body is rotatably connected with the rotating shaft through a shaft sleeve, a hollowcavity is formed in the rotating shaft, seal rings are symmetrically mounted on the upper end and the lower end of the hollow cavity in a seal manner, a rotating rod is jointly mounted on the centersof the two seal rings in a penetrating manner, the rotating rod is in seal sliding connection with the two seal rings, two semi-arc grooves are formed in the rotating shaft symmetrically, connecting rods are fixedly connected to the two ends of the rotating rod, the ends, away from the rotating rod, of each connecting rod is fixedly connected with the door body through the corresponding semi-arc groove, the service life is long, flowing speed of hydraulic oil in the door is limited by a flow limiting hole, when the door body bears strong thrust, the hydraulic oil cannot rapidly flow, the aim of reducing the rotating speed of the rotating rod and the door body can be achieved, the acute collision of the door body and a door frame can be avoided, the effect of protecting the door body and the door frame can be achieved, and generation of the noise is reduced.

Description

technical field [0001] The invention relates to the technical field of doors, in particular to a door with a buffer effect. Background technique [0002] With the development of the society and the progress of the economy, the types of doors are becoming more and more abundant. People will choose doors with different functions according to the usage scenarios. Generally, automatic glass doors are installed; in study and office areas, buffer and silent doors are mostly installed. [0003] The common cushioning mute door is mostly to add a rubber strip around the door or the door frame. When the door is closed, the rubber strip can buffer the collision between the door body and the door frame, so as to achieve the effect of noise reduction. However, after a long time of use, the rubber strip will inevitably Wear or tear will occur, and at this time, the purpose of cushioning and silence cannot be achieved. In addition, in order to prevent the rubber strip from falling off dur...

Problems solved by technology

[0003] The common cushioning silent door is mostly to add a rubber strip around the door or the door frame. When the door is closed, the rubber strip can buffer the collision between the door body and the door frame, so as to achieve the effect of noise reduction. However, after a long time of use, the rubber strip will inevitably Wear or tear will occur, and at this time, the purpose of cushioning and silence cannot be achieved. In addition, in order to prevent the rubber strip from falling off during processing, it is often embedded in the door frame or door body. Therefore, replacing the rubber strip also has certain advantages. Difficulty, even the structure of the door body will be damaged when it is replaced. Therefore, we propose a door with a cushioning effect
