AUTO LOCKING DEVICE FOR SLIDING WINDOW

摘要

The present invention provides an auto locking device for a sliding window and a sliding door, which is installed with an auto locking assembly at a window and is capable of minimizing a collision noise between a locker and a striker by rapidly reducing a close speed of the window and buffering a collision between the locker and the striker just before the locker of the auto locking assembly collides with the striker of a window frame at the time of closing the window and preventing the deterioration and the damage of a component caused by the collision between the locker and the striker. According to the present invention, the auto locking device for a sliding window and a sliding door further comprises a buffer device which reduces the close speed of the window and buffers the window at a position at which the striker approaches the locker of the window frame. The buffer device comprises: a fixed barrel body which is fixed to a case of the auto locking assembly and defines a reduction exhaust hole; a moving barrel body which is movably installed in the fixed barrel body and defines an acceleration exhaust groove; a pressurizing member which is movably installed in the moving barrel body; a buffer member which is made of a silicon material and is fixed to a front end of the pressurizing member; a reduction adjustment member which is provided between the inside of the fixed barrel body and the reduction exhaust hole and adjusts a size of the reduction exhaust hole; and a length adjustment member which is provided in the moving barrel body and adjusts a length of a front end side of the moving barrel body.
