The present invention relates to an out-body for a digital door lock, of which the structure is simple so that the out-body can be easily assembled and disassembled. A digital door lock and a bracket of the prior art have a complex coupling structure and require a plurality of coupling units such as a bolt and a nut, so that it is difficult to assemble and disassemble the digital door lock and the bracket. To solve the problems, the present invention provides an out-body coupling structure for a digital door lock including an in-body and an out-body coupled to an inside plate and an outside plate of a bracket. A rotation member 20 having a gear formed on outer circumference surface is rotatably coupled to the outside plate. Gears are formed at both sides of the rotation member 20 such that the rotation member 20 moves up and down by the rotation of the rotation member 20. The rotation member 20 is coupled to first and second elevation members 30 and 40 engaged with the gears. Front ends of the first and second elevation members 30 and 40 are inserted into or separated from a coupling unit 71 formed in the out-body 70 so that the out-body 70 is fixed to or disassembled with the outside plate 11. Thus, according to the present invention, in state that the in-body is coupled to the digital door lock, the out-body can be easily coupled to or disassembled with the in-body by using a screwdriver, so that the digital door lock can be more conveniently maintained and managed. Further, since there is no need to use a coupling unit such as a bolt or a nut to couple the out-body to the bracket, anybody can install the door lock even if an installer is not an expert. |
