Spring bolt damp buffering mechanism

Abstract

The invention discloses a spring bolt damp buffering mechanism which comprises a spring bolt and a spring bolt driving part which drives the spring bolt to move, wherein a sliding plate is arranged onone end part of the spring bolt, and a buffer device for slowing down the pop-up speed of the spring bolt is arranged on one side of the sliding plate; the buffering device comprises a damper and a linking sheet hinged to the sliding plate, a chute is formed in one end part, close to the damper, of the linking sheet, and the damper is provided with a linking part matched with the chute; when thespring bolt is popped-up outward under the action of a magnetic force, the linking part will lean against the side wall of the chute to hinder outward movement of the sliding plate, so that the pull force of the linking sheet will counteract a part of magnetic force, so as to slow down the pop-up speed of the spring bolt, and therefore, the colliding noise between the spring bolt and a buckle boxis reduced; when the spring bolt needs to retract to a lock body, the linking part can move on the chute, so that the linking sheet will not hinder backward movement of the sliding plate, the spring bolt can retract smoothly to the lock body, and the condition that the spring bolt retracts to the lock body is not affected.

Description

technical field [0001] The invention relates to the field of door locks, more specifically, it relates to a damping buffer mechanism for a deadbolt. Background technique [0002] At present, the magnetic lock body widely used in the market includes a buckle box and a lock body. The lock body is provided with a lock tongue that can slide back and forth. , to achieve the purpose of closing the door. Due to the large magnetic force, the dead bolt moves at a relatively high speed and acceleration, causing the dead bolt and the buckle box to collide with each other and generate noise. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a damping and buffering mechanism for the deadbolt, which slows down the moving speed of the deadbolt and reduces noise. [0004] In order to achieve the above object, the present invention provides the following technical solution: comprising a deadbolt and a deadb...
