Device for burglary-resisting door automatic locking shock attenuation noise control

The utility model discloses a device for burglary-resisting door automatic locking shock attenuation noise control, including casing (1), upper and lower elasticity pushing mechanism (2), lock body mechanism (3), trigger mechanism (4), and delatch mechanism (6) are fixed with spring bolt (5) on the planker of lock body mechanism (3), and spring bolt (5) automatic the locking in the lock body mechanism (3) is controlled through upper and lower elasticity pushing mechanism (2) in trigger mechanism (4), and unblank spring bolt (5) that delatch mechanism (6) were controlled in the lock body mechanism (3) through the planker of lock body mechanism (3), be fixed with damping machanism (8) on the planker of said lock body mechanism (3), apron (14) is fixed including attenuator (7) in damping machanism (8), and fixed plate (15), fixed plate (15) are fixed on the planker of lock body mechanism (3), and install on fixed plate (15) through fixed apron (14) attenuator (7), and damper rod (9) the roof pressure of attenuator (7) is on casing (1) of panel side after adopting this structure, it is equitable to have a simple structure, and the assembly is simple and convenient, and the flexible operation is light, shake for a short time, and the noise hangs down, job stabilization advantage such as reliable
