When also extremely influence outward appearance.
The content of the invention
, need not be in Men Shangan it is an object of the invention to provide one kind in order to overcome the shortcomings of door chain presence in the prior art
The door chain of Button Block is filled, the main body of the door chain is a base and a door handle, and base is provided with mounting hole, can be by mounting hole the bottom of by
Seat is arranged on doorframe or metope, and chain is provided with below base, and chassis interior is provided with strength magnet, and the tapered end of chain one end can be inhaled
It is attached on base, the surface of door handle is provided with chute and notch, and at closing time, tapered end is nested into chute by notch,
It is very convenient.
In order to reach the purpose of the present invention, the technical solution adopted for the present invention to solve the technical problems is：By base, peace
Fill hole, chain, strength magnet, suspension part, tapered end, door handle, chute, notch composition, it is characterised in that the inside of the base
Provided with a strength magnet, a suspension part is provided with below base outer surface, and base upper and lower ends are equipped with mounting hole, the chain
One end suspension be connected on suspension part, the other end of chain is provided with a tapered end, and the surface of the door handle is provided with a chute, door
The right-hand member of handle upper hopper chute is provided with a notch, and tapered end and chute match can nested encryptions, during installation, user can be first by door
Handle is mounted on a door, then base is fixed on the metope OR gate frame of door handle side through mounting hole with screw, finally
Chain is hung on the suspension part being connected on base, when locking a door, the tapered end of chain one end can be passed through door knob by user
Notch on hand is nested into chute and slides to bottom, and during enabling, tapered end only need to be taken out and inhaled from chute by user
It is attached at the strength magnet on base.
Simple the beneficial effects of the invention are as follows design, reliability and durability, practicality is big.
