Problems solved by technology

[0005] For this reason, the technical problem to be solved by the present invention is that the deadbolt in the lockset in the prior art collides with the pin hole or the lock body in the door frame when it is locked out or retracted, and produces abnormal noise, which generates noise, and then provides a Low-noise mechanism capable of reducing the noise produced by the collision between the lock tongue and the pin hole in the door frame when the lock is released, and the lockset with the mechanism

Embodiment 1

[0025] Such as figure 1 Shown is the low-noise mechanism of the present invention, including a rack 1, a transmission gear 6 and an energy storage flywheel 7. One end of the rack 1 in the longitudinal direction is installed on a deadbolt assembly 10, and the rack 1 and A transmission gear 6 meshes, and the transmission gear 6 is coaxially fixed with the energy storage flywheel 7 .

[0026] Further, in this embodiment, on the basis of the above-mentioned embodiments, multiple sets of gear sets are arranged between the rack 1 and the transmission gear 6, and each set of gear sets includes a large gear and a small gear set coaxially. gear, the rack 1 meshes with the pinion 3 of the first gear set, the large gear 2 of the first gear set meshes with the pinion 5 of the second gear set or the transmission gear 6, as figure 2 shown. In this embodiment, there are two groups of gear sets between the transmission gear 6 and the rack 1, which are respectively the first gear set and th...

Embodiment 2

[0031] In this embodiment, on the basis of the above-mentioned embodiments, the rack 1 is movably connected with the deadbolt assembly 10, and a guide hole 8 is formed on the rack 1, which is fixed on the lock housing and cooperates with the guide hole 8. Pin 9, the guide hole 8 has an inclined portion 12, the inclined portion 12 forms a certain angle with the locking direction of the rack 1, when the lock tongue assembly 10 is locked, the guide hole 8 is opposite to the pin 9 The movement drives the rack 1 to drive close to the energy storage flywheel 7, and when the deadbolt assembly 10 retracts, the rack 1 drives away from the energy storage flywheel 7, as image 3 As shown, that is, the angle between the end of the guide hole close to the deadbolt assembly 10 extending away from the end of the deadbolt assembly 10 and the direction in which the deadbolt is locked is an obtuse angle. When locking out, the pin 9 in the guide hole 8 is at one end close to the deadbolt assembl...

Abstract

The invention discloses a low-noise mechanism and a lock with the same. The low-noise mechanism comprises a rack (1). One end, in the length direction, of the rack (1) is mounted on a spring bolt component (10); the rack (1) is meshed with a transmission gear (6); an energy-storage flywheel (7) is fixedly arranged on and is coaxial with the transmission gear (6). The lock with the low-noise mechanism comprises a lock shell, the spring bolt component (10), a driving component and the low-noise mechanism. The lock shell is provided with a faceplate. A spring bolt hole is formed in the faceplate. The spring bolt component (10) comprises a spring bolt and a guide plate fixedly connected with the spring bolt. The driving component is used for driving the spring bolt component (10) to extend or retract. By the low-noise mechanism, the technical problem that noises are generated due to the fact that abnormal sounds are caused during collision between the spring bolt and a pin hole of a door fame when the spring bolt extends in the prior art is solved.

Description

technical field [0001] The invention relates to a lock, in particular to a low-noise mechanism for the lock and the lock with the mechanism. Background technique [0002] The lockset in the prior art mainly includes components such as a lock body, a secondary lock body, a dead bolt and a mechanical transmission mechanism. When locking the door, under the action of the mechanical transmission mechanism, the lock tongue quickly passes through the lock body and inserts into the auxiliary lock body, so as to achieve the purpose of locking. It has a strong impact force, causing the deadbolt to collide when inserted into the pin hole in the door frame, making noise. [0003] In order to avoid the generation of noise, a damping device is provided in the lock in the prior art, such as the end where the dead bolt contacts the pin hole in the door frame is covered with a flexible non-metallic material, but due to the nature of the dead bolt and the non-metallic material Different, u...
