Inside-door lock

Abstract

The invention discloses an inside-door lock. The inside-door lock comprises a box body, a latch bolt device, a dead bolt device and a reversing device, wherein the latch bolt device, the dead bolt device and the reversing device are arranged in the box body; the latch bolt device comprises a latch bolt body and a latch bolt shifting block used for retracting the latch bolt body, the dead bolt device comprises a dead bolt body and a dead bolt shifting block used for retracting the dead bolt body, and the reversing device is used for rotating the latch bolt shifting block; the latch bolt shifting block is provided with a first shifting arm, the dead bolt shifting block is provided with a second shifting arm, and the first shifting arm abuts against the second shifting arm; when the latch bolt shifting block rotates, the first shifting arm of the latch bolt shifting block shifts the second shifting arm of the dead bolt shifting block to enable the dead bolt body and the latch bolt body to be retracted at the same time; the latch bolt shifting block is provided with a knob rotary block, and the reversing device is fixedly connected with a handle shifting block. The inside-door lock has the beneficial effects the steering is flexible, adaptability is high, and the internal structure is simplified.

Description

technical field [0001] The invention relates to the technical field of lock making, in particular to a door lock body, in particular to a door lock body for an electronic lock with a motor clutch structure. Background technique [0002] At present, the electronic lock bodies on the domestic market are mainly hotel lock bodies and anti-theft door lock bodies. These two lock bodies have three obvious deficiencies. One is that the lock body is relatively large in size, and the other is that the structure is relatively complicated. The mute effect is not good, and it is not suitable for the electronic lock on the door of the room. There is also an electronic lock body for a room door on the market with a motor-driven square tongue structure. This structure also has obvious shortcomings. First, the power consumption required by the motor to drive the lock tongue is too large. Second, there are too many components and the structure is complicated, and reliability is difficult to g...

AI Technical Summary

Problems solved by technology

[0004] One is that when the lock body is changing the left and right doors, it is necessary to open the lock body, take out all the relevant dead bolts, and adjust the position before they can be converted and installed. This makes the installation more troublesome, and when adjusting the dead bolt, due to installation errors , often causing damage to the lock

[0005] The second is that there are many functional requirements for the lock body, resulting in a complex structure of the lock body. The panel for installing the lock body requires a large space, and it is necessary to open multiple holes on the door to fix it, which destroys the structure of the door.

[0006] The third is that the current lock body uses three or more independent parts to control the opening or closing of the lock through the movement of the connecting rod. The number of parts used is large, the assembly is difficult, and the failure rate is high, and the mechanical structure is not enough. Stablize

[0007] 4. After the lock body of the existing design is locked in the door (the oblique tongue and the dead tongue all pop out), it needs to use a key or an administrator to open it, so that in critical situations, especially dangerous situations such as fire, the escape of people locked inside become a problem, the safety of the owner cannot be guaranteed to the greatest extent

[0008] Fifth, the existing door lock body generally does not have a clutch motor structure, which is difficult to apply to electronic door locks
