Problems solved by technology
There is a problem: when the driver is pressed to lock, during the process of pressing the driver, the driver rotates between the sliding positioning tongue and the inclined groove, and the locking action is not completed until the sliding positioning tongue snaps into the positioning slot, but due to the drive The sliding of the sliding part during the pressing process makes it difficult for the sliding positioning tongue to snap into the positioning slot, resulting in the inability to unlock and posing a safety hazard; when the friction between the finger and the pressing part on the other side is too large, it is not convenient for the rotation of the driving part to realize the lock. combine

The invention discloses a novel door lock. The novel door lock comprises an outer handle assembly, an inner handle assembly, a clutch and a safety mechanism. The inner handle assembly comprises a ballchannel. The safety mechanism comprises a brake rod and a driving device. The driving device comprises a guide slot formed axially in the side face of the ball channel. A sleeve is arranged n the ball channel. An inclined slot formed axially is formed in the side face of the sleeve. A brake rod sleeve hole matched with the brake rod is formed in the end surface of the end surface of the sleeve. Apositioning slot is formed in the bottom end of the inclined slot. A spring and a driving part are successively arranged in the sleeve. A sliding positioning tongue arranged on the peripheral surfaceof the driving part is arranged on the driving part. When the sliding positioning tongue is pressed by the driving part, the driving part slides along a guide slot, and the sleeve rotates along the inclined slot and is locked and positioned in the positioning slot. The novel door lock has the characteristic of being safe and convenient to lock, and potential safety hazards are eliminated.
Description
[technical field] [0001] The invention relates to a novel door lock. [Background technique] [0002] At present, most of the door locks are three-bar door locks, including outer components, inner components, insurance mechanisms and clutches. Cover, ball pass, drive frame and inner handle; the inner baffle is embedded in the inner block cover, the ball pass is rotatably matched with the inner baffle plate and the inner block cover, the drive frame is set at one end of the ball pass, and the inner handle is set at the ball pass the other end of the figure 1 As shown, when locking is required, the user presses the driving part in the driving device, and the driving part rotates at a certain angle under the interaction of the sliding positioning tongue and the inclined groove, so that the brake lever rotates accordingly and the lock is pressed with the driving part. The stop tab is snapped into the lock slot to lock the safety mechanism, and when it needs to be unlocked, just...
