Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pivot hinge with an energizing function that can energize between a housing and a door by wire.

[0002]

[Prior art]

 With the progress of computerization of locking devices and crime prevention devices used for doors, it is necessary to pass electricity from the housing to the door, but with the conventional pivot hinge, it is inserted and supported in the shaft hole of the base plate. Since the shaft rod is a solid body, the electric wire could not be drawn into the door side through the pivot hinge. For this reason, there is the complexity of having to separately provide through holes for wiring in the housing and door.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a pivot hinge with an energizing function that can easily energize between a door and a housing by wire.

[0004]

[Means for Solving the Problems]

 The pivot hinge according to the present invention will be described below with reference to the accompanying drawings. The pivot hinge includes a base plate 2 fixed to a door 1; an upper part 5 is inserted into a shaft hole 11 of a housing 10; and a lower part 6 is a base. The intermediate flange portion 7 is inserted into the shaft hole 3 of the plate 2, and the intermediate flange portion 7 is composed of the shaft rod 4 sandwiched between the base plate 2 and the housing 10. The through hole 8 penetrating vertically is formed in the central portion of the shaft rod 4. A cutout portion 9 is provided on the outer peripheral portion of the shaft rod 4 so as to communicate with the through hole 8.

[0005]

[Action]

 Although the electric wire 12 is drawn from the housing 10 to the door 1 by assembling the pivot hinge and attached to the door 1 and the housing 10, both ends or one end of the electric wire 12 is for equipment or power distribution. When the electric wire 12 is not yet connected to a terminal or the like, the electric wire 12 is inserted into the through hole 8 of the shaft rod 4 from above or below the shaft rod 4.

For the convenience of wiring and mounting of the device, the electric wire 12 is passed through the shaft hole 11 of the housing 10 and the escape hole 17 of the door 1, and the device, the distribution terminal and the like are connected to both ends of the electric wire 12 first. In some cases, the electric wire 12 is inserted into the through hole 8 of the shaft rod 4 from the side of the shaft rod 4 through the cutout portion 9, and then the pivot hinge is assembled and attached to the door 1 and the housing 10. .

In the illustrated embodiment, the shaft hole 3 on the side of the base plate 2 is provided at one corner of the base plate 2, and the mounting holes 13 are provided at the remaining three corners of the base plate 2. . The fixing screw 15 of the base plate 2 is inserted into the mounting hole 13 from the mounting hole 14 of the upper plate portion 18 of the door 1, and the base plate 2 is fastened and fixed by the nut 16 screwed to the screw 15. If the mounting hole 13 of the base plate 2 is a screw hole, the nut 16 can be omitted.

The shaft hole 11 on the side of the housing 10 is provided in the edge plate portion 19 of the opening of the housing 10. The intermediate flange portion 7 of the shaft rod 4 is fitted in the escape hole 17 of the upper surface plate portion 18 of the door 1. The upper surface of the intermediate collar portion 7 contacts the lower surface of the edge plate portion 19, and the lower surface of the intermediate collar portion 7 contacts the upper surface of the base plate 2.

[0009]

[Effect of device]

 As described above, in the pivot hinge of the present invention, the upper portion 5 is fitted in the shaft hole 11 of the housing 10, the lower portion 6 is fitted in the shaft hole 3 of the base plate 2, and the intermediate flange portion 7 is formed as the base plate 2. Since the through hole 8 that penetrates vertically is provided in the central portion of the shaft rod 4 that is sandwiched between the casings 10, and the cutout portion 9 that communicates with the through hole 8 is provided in the outer peripheral portion of the shaft rod 4. Alternatively, by using the through hole 8 and the cutout portion 9, the electric wire 12 can be easily drawn from the housing 10 to the door 1, and the complexity of separately providing a through hole for wiring in the housing or the door is released. To be done.
