Movable pulley sliding door buffer assembly

Abstract

The invention relates to a movable pulley sliding door buffer assembly. The movable pulley sliding door buffer assembly comprises a buffer and a trigger assembly; the buffer comprises a buffer body, adoor opening sliding block, a door closing sliding block, a movable pulley, a tension spring and a damping oil cylinder; a door closing sliding groove and a door opening sliding groove are formed inthe bottom of the buffer body side by side, and a barrier strip is arranged between the door closing sliding groove and the door opening sliding groove in parallel; the door closing sliding block is slidably connected into the door closing sliding groove, the movable pulley is installed on the door closing sliding block, the movable pulley is located above the door opening sliding groove and slides in parallel with the door opening sliding groove, a connecting wire is wound around the movable pulley, one end of the connecting wire is fixed to the buffer body, and the other end of the connecting wire is connected with the door opening sliding block slidably connected into the door opening sliding groove. By means of the characteristics of the movable pulley, under the same acting condition,the opening path of the buffer is prolonged to two times of the distance in the door opening process, the needed force can be reduced by one time, the purpose of saving labor is achieved, and the useexperience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of sliding door buffering, in particular to a moving pulley sliding door buffering assembly. Background technique [0002] Sliding door is a common door, especially suitable for some occasions where the space is relatively narrow. For some high-end villa doors, balcony doors of buildings, and doors used in some wardrobes, sliding doors are often people's common choice. [0003] In the process of pushing or closing the sliding door, sometimes because of the long stroke, people will need to use a certain force to achieve a certain speed in the process of closing or opening, and use the inertia of the door itself to slide to open or close the door In this way, when the door reaches the end of the stroke, due to the inertia of the door itself, it will cause more or less collisions between the door and the door frame at the end of the track, which may not only generate a lot of noise, but also cause damage to the...

Problems solved by technology

[0003] In the process of pushing or closing the sliding door, sometimes because of the long stroke, people will need to use a certain force to achieve a certain speed in the process of closing or opening, and use the inertia of the door itself to slide to open or close the door In this way, when the door reaches the end of the stroke, due to the inertia of the door itself, it will cause more or less collisions between the door and the door frame at the end of the track, which may not only generate a lot of noise, but also cause damage to the door frame after long-term use , in order to avoid this situation, most of the current installation of sliding door buffer

[0004] For the sliding door buffers on the market, if the sliding door needs to be closed in place when the door is closed, a greater force (about 2 times) is required to open the buffer when the door is opened, which is laborious and affects the user experience
