The present invention relates to an auxiliary door lock device and a safety ring,

By using the safety ring in combination with the auxiliary door lock,

As the door lock is unlocked at the same time, the door is opened automatically with the safety ring locked, and the front door is opened completely after the identification of the first stranger visitor to prevent the victim of crime. It can be.

In general, the front door of the home is equipped with safety hooks and auxiliary door locks.

Auxiliary door locks are intended to increase security by additionally attaching to the existing entrance.

However, secondary door locks are only more secure and do not have the primary identity of visitors. In addition, the safety ring is installed on the front door, so you have to operate it yourself, but almost all homes open the front door to strangers without a safety ring, such as a virtual experiment pretending to be a courier from a broadcasting station.

Before a visitor can open the door, he must fill the safety ring and confirm his identity, and then release the safety ring and open the front door completely.However, at home, the front door is completely open to strangers without the safety ring. The situation is hit.

Therefore, the present invention combines the safety ring and the auxiliary door lock so that the safety ring is always automatically taken off when the door lock is released. By doing so, it aims to prevent becoming a victim of crime.

This design is a device that combines a safety ring and an auxiliary door lock,

At the bottom of the auxiliary door lock clasp, a cylindrical shape and a lower part of the cylinder have a slightly concave shape, and a safety loop is formed vertically downward.

At the bottom of the auxiliary door lock is formed a long bar-shaped safety ring formed with a hole along the inner diameter.

The auxiliary door lock is provided with a main knob and an auxiliary knob.

The main knob locks the door lock by operating the safety ring and the auxiliary knob at the same time, and the auxiliary knob opens and closes the door lock only.

The main knob extends into the door lock, and the left portion is square, the right portion is circular, and the rotary bundle a formed with the protrusion a is formed at the bottom of the left portion. The protrusion a of the rotary bundle a comes into contact with the plate part a groove formed in the side part. By rotating the main knob, the projection a of the rotary bundle a contacts the groove of the plate portion a, and the rotary bundle a leads the plate portion a to move up and down. Plate a is vertically extended from the safety ring bar and the folding band formed inside the auxiliary door lock is combined with the clearance in the inner diameter of the cylindrical ring, and the cylindrical ring is in contact with the projection larger than the outer diameter of the cylindrical ring formed at the upper part of the folding band, and is led up and down. . As the folding bar moves to Shanghai East, the safety bar extending from the folding bar moves up and down, so that the safety ring is caught and released from the safety bar. The folding bar has a play on the cylindrical ring and the folding bar can be rotated so that the safety bar extending from the folding bar can rotate. The door lock is formed inside the door lock to fix the spring, and the upper end of the rotating bundle a is formed with a hook to catch the spring. Both ends of the spring are fixed to one side of the door lock and the upper ring of the left side of the rotating bundle a. It keeps being rotated to the left and right ends.

An auxiliary knob extending into the auxiliary door lock engages a rotating bundle b in which a left portion is a square, a right portion is a circular shape, and a protrusion b is formed at the bottom of the left portion. The protrusion b of the rotary bundle b is in contact with the plate part b in which the groove is formed in the side part. By rotating the auxiliary knob, the protrusion b of the rotating bundle b contacts the groove of the plate portion b, and the rotating bundle b leads the plate portion b to move up and down. A lock is attached to the plate part b so that the lock is locked and released as the plate part b moves up and down. A protrusion is formed on the right side of the rotating bundle b, and a stopper is coupled to the side of the auxiliary door lock facing each other by penetrating inside and outside. After locking the door lock, the stopper is pushed into the door lock and the end of the stopper is caught by the right protrusion. It is not locked completely. The door lock is formed inside the door lock to fix the spring, and the upper end of the rotation bundle b is formed with a hook to catch the spring. Keeps rotating to the left and right ends. Here, the safety ring driving unit is formed above the door lock driving unit.

The auxiliary knob is coupled to the inner diameter of the main knob. A space portion is formed in which a predetermined portion of the inner diameter of the main knob is opened, and a protrusion that can be inserted into the space portion of the main knob is formed in the outer diameter of the subsidiary knob. And the auxiliary knob rotates together to lock the door lock. When the main knob is rotated in reverse to close the door and release the safety ring, only the safety ring is released, and the protrusion of the auxiliary knob is formed so as not to be caught in the upper part of the main knob. The auxiliary knob does not rotate so the door lock lock is released. State is maintained. The auxiliary knob protrusion can operate arbitrarily in the space of the inner diameter of the main knob so that only the door lock lock can be opened and closed.

A groove is formed in the outer diameter of the safety ring bending band, and a positioning hole is formed on the inner surface of the cylindrical ring. The corrective positioning projection is pushed by the spring, and when the hole of the safety hook bar comes in a position where it can be caught in the safety loop projection, the corrective positioning projection is clicked into the bending groove.

As above, the positioning protrusion is to ensure that the safety ring is always located at the position where it can be accurately caught on the protrusion of the safety hook latch. In addition, the anti-rotation protrusion is provided vertically on the upper surface of the cylindrical ring, so that the folding bar does not rotate toward the door and rotates toward the door frame, so that the safety bar extending from the folding bar rotates toward the door frame.

The safety bar is rotated as above to relieve the hang of the safety bar when moving, and the reason for rotating the safety bar only toward the door frame is to rotate the door frame in the direction of the door frame as necessary when moving. When closing the front door, the safety bar touches the door frame, so the front door can only be closed by putting the safety bar back in place so that the safety bar always stays where it can catch the safety loop. This is to prevent the door from opening without knowing that the bar is not in a position to catch the safety loop.

When you open the front door like a conventional safety ring, you do not hang it.

At the same time the door lock is released, the safety hook is always locked automatically.

By opening the front door a little while holding a safety loop, you can identify the identity of the first-time stranger and prevent you from becoming a victim of crime.

 In addition, the safety hooks in most homes are easily released with a thin tool like a ruler outside the front door.

However, the safety loop of the present invention can not be released from the outside of the front door unless the insider releases the door, and in the open state of the front door can never be released, the security is more highlighted.

Hereinafter, the present invention will be described with reference to the accompanying drawings.
