The application discloses a mute door lock assembly and belongs to the technical field of locks. The mute door lock assembly comprises a lock body, a slanting lock tongue and a main lock column which are arranged on the lock body in an extendable mode, and a lock cylinder hole is formed in the lock body. The lock body comprises a lock body and a lock cover, the lock body and the lock cover are fixedly connected through screws, mounting holes are formed in the lock body and the lock cover, a mounting column is arranged between the lock body and the lock cover, screw holes are formed in the mounting column, the mounting column is opposite to the mounting holes, the screws are connected with the screw holes through the mounting holes, and the mounting of the lock body and the lock cover is realized. A mute structure is further arranged in the lock body. The mute door lock assembly has the beneficial effects that the first magnet and the second magnet are arranged, the second magnet generates a certain repulsive force on the first magnet when the first magnet moves to the limit position, the push plate is prevented from impacting the limiting structure, i.e., the lock body, and the impact sound is reduced.

The utility model relates to guide rail technical field discloses a kind of mute guide rail device, including guide rail, the guide rail surface is provided with mute component, the mute component inside is provided with lubricating component.The utility model can significantly reduce the noise in the process of movement by the damping mute wheel, this is realized by using the material with sound-absorbing effect such as rubber, PU etc or using specific structure design, when damping mute wheel drives limit shaft to rotate with auxiliary nut as center, damping mute wheel is under the long-time friction of guide rail surface, easy to cause damping mute wheel breakage, when needing to replace damping mute wheel, by fixing fixed bolt and auxiliary nut simultaneously, then rotating auxiliary nut, make auxiliary nut separate from fixed bolt bottom surface, make auxiliary nut drive limit shaft, limit shaft drives damping mute wheel to separate downward, so as to separate damping mute wheel from guide rail to facilitate its replacement, to ensure its mute effect.
