Description

technical field [0001] The present invention relates to a fastening bolt and a digital door lock device with a fastening bolt. Specifically, it can be easily installed on outdoor and indoor doors, sliding doors, etc. without destroying existing doors equipped with mechanical door locks. Fastening bolts on all doors with handrails and digital door locks with fastening bolts. Background technique [0002] Generally speaking, in order to prevent and protect security, door locks are provided at the entrances and exits of families or companies and stores. In recent years, digital door locks have gradually replaced mechanical door locks. [0003] In order to activate these digital door locks, a method of touching an electronic key to a contact part of the electronic key, a method of pressing a keyboard using a mechanical switch such as a tact switch or a membrane switch to input a password, and a method of using a fingerprint are currently used.

Problems solved by technology

[0010] In addition, in the existing digital door lock device, in order to transmit the rotational force from the handle of the door lock body whose interval is determined according to the thickness of the door to the side of the latch bolt that locks the door on the door frame, it is necessary to directly connect the rotary joint assembly to the door frame. It is troublesome to insert into the main body of the indoor and outdoor door locks

[0011] In addition, in the conventional digital door lock device having fastening bolts, when fastening the indoor and outdoor door lock bodies, it is difficult to adjust the interval between the door lock bodies according to the thickness of the door. When installing on both sides of the door and performing fastening operations, problems such as falling bolts and reconfirmation of the positions of the fastening holes do not correspond to each other are troublesome. In addition, when the size of the through hole for fastening formed in the door When it is small, the spacing of the fastening bolts is not suitable, and the holes need to be enlarged

[0012] In addition, in the conventional digital door lock device having fastening bolts, when fastening the door lock bodies on the indoor side and the outdoor side, after inserting one side, when installing the bolts to fasten the other side, due to the applied The force of the bolt, being pushed back, makes it difficult to install the bolt
