The coupling unit is for mutually coupling the outdoor housing 310 and the indoor housing 210 to the door 1. The coupling unit includes a reinforcing member 410, a pair of first bolt members 420, and a pair of second bolt members 430.

The reinforcing member 410 is coupled to support the outdoor side of the door (1). The reinforcing member 410 includes a base portion 411 that is in contact with and supported on the outdoor side of the door 1, and a flange portion 413 that is orthogonally connected to the base portion. Four through holes 412 are formed in the base 411. Four through holes 412 are disposed coaxially with four through holes 2 formed through the door 1, respectively. The flange portion 413 is in contact with and supported on the inner side surface of the outdoor housing 310.

The pair of first bolt members 420 are inserted into the through holes 412 of the reinforcing member and the through holes 2 of the door, respectively. The pair of first bolt members 420 have male threads 421 and heads 423, respectively. The male screw portion 421 is a portion that is bolted to the first female screw hole (212). The head part 423 is a part connected to the male screw part 421 via the shank part 422 and is contacted and supported by the base part 411 of a reinforcement member. In addition, the head 423 is formed to have a diameter larger than the diameter of the male screw portion 411 and is disposed between the indoor housing 210 and the door 1 and is not exposed to the outside. Each first bolt member 420 is inserted into the through hole 412 of the reinforcing member and the through hole 2 of the door at the outdoor side of the door 1 to be screwed to the first female screw hole 212 of the indoor housing. do. When the first bolt members 420 are coupled as described above, the interior housing 210 and the reinforcement member 410 are pressed in the direction of approaching the door 1, respectively, and are firmly fixed to the door 1.

Then, the pair of second bolt member 430 is inserted in the direction opposite to the insertion direction of the first bolt member 420. The pair of second bolt members 430 have male threads 431 and a head 433, respectively. The male screw portion 431 is a portion that is bolted to the second female screw hole 312. The head portion 433 is a part connected to the male screw portion 431 via the shank portion 432 and is in contact with and supported by the indoor housing 210. And, the head portion 433 is formed to have a diameter larger than the diameter of the male screw portion 431, and unlike the head portion 423 of the first bolt member has a countersink shape. When each of the second bolt members 430 is coupled, the outdoor housing 310 and the indoor housing 210 are pressed in the direction of approaching the door 1, respectively, and thus are firmly fixed to the door. When the pair of second bolt members 430 are coupled to each other, the first bolt members 420 are pressed by the outdoor housing 310 in the insertion direction of the first bolt members 420. That is, when the pair of second bolt members 430 is tightened after being inserted, the outdoor housing 310 and the indoor housing 210 are doors 1 as the tightening force of the second bolt members 430 is increased. The inner surface of the outdoor housing 310 is in contact with the head 423 of the first bolt member, and at that moment, the inner surface of the outdoor housing 310 is the first bolt. The head 423 of the member is pressed. In the drawing, the inner side portion of the outdoor housing 310 which presses the head 423 of the first bolt member is indicated by the member number "313".

As such, when the inner surface of the outdoor housing 310 presses the head 423 of the first bolt member, the second bolt member 430 is excessively tightened, and the fastening force of the second bolt member 430 is excessive. Even if it is properly applied, it is possible to prevent the phenomenon that the door 1 is pressed and deformed. Therefore, the installation operation is facilitated, and furthermore, the outdoor housing 310 and the indoor housing 210 can be more firmly fixed.

In addition, the pair of first bolt members 420 are arranged to have equal intervals along the circumferential direction on the virtual circle, and the pair of second bolt members 430 also have equal intervals along the circumferential direction on the virtual circle. Since it is arranged to achieve, the fastening force of the first bolt member 420 and the second bolt member 430 is applied in a balanced manner.

In addition, the bolt portion 440 of the third bolt member 440 is coupled to the flange portion 413 and the outdoor housing 310 of the reinforcing member.

As described above, in the present embodiment, the second bolt member 430 is configured to be bolted in a state where the first bolt member 420 is bolted, and is particularly outdoors in the head 423 of the first bolt member. Since the inner surface of the side housing 310 is in contact with each other, even if the fastening force is increased when the second bolt member 430 is engaged, the door 1 may be pressed and deformed. Therefore, the indoor housing 210 and the outdoor housing 310 can be more firmly fixed. As such, when the indoor housing 210 and the outdoor housing 310 are firmly fixed, security against physical hacking using a tool called 'Paru' can be improved.
