Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a ventilation fan mounting structure.

[0002]

[Prior art]

 Ventilation fans will be installed in buildings such as parking lots and distribution warehouses, but for conventional installation, a ceiling wall 10 made of concrete or the like in the completed building is used for hanging as shown in FIG. After the frame 11 is first attached, the electric wiring 12 is provided, and the ventilation fan 13 is attached to the lower end of the frame 11.

[0003]

[Problems to be solved by the device]

 Installing the ventilation fan including the frame and wiring work after waiting for the completion of the building as described above is generally a work in high places, which is a dangerous and troublesome work. The present invention is intended to solve such a problem.

[0004]

[Means for Solving the Problems]

 The present invention secures a connector female of a power cord on the lower surface side of a ceiling wall surface of a building such as a parking lot or a distribution warehouse, and allows slits and engagements that allow lateral rotation and allow engagement and fastening. Attach the terminal box with fittings, while the ventilation fan is attached to the hanging frame, and the upper side of the hanging frame is engaged with the connector male from the ventilation fan motor and the fittings of the terminal box. It features a notch that fits together, and the ventilation fan is removable via the terminal box.

[Embodiment of device]

 FIG. 1 is a perspective view of an assembly part of the present invention, in which A shows a terminal box 1 attached to a ceiling wall, and one side of which is a square frame is connected to a power line 2. A switch box 4 provided with a connector female 3 in a protruding state is attached, and a member for engaging a notch of a suspending frame body described below on the lower lower surface of the center of the square frame to bring it into a suspending state. A fitting 5 is attached. In the drawings, 7a and 7b are arc-shaped slits formed by allowing the hanging frame body to be described later to rotate in the 180 ° range in the left-right direction, and 6a and 6b fix the arbitrary positions of the rotation. Bolts and nuts for fixing the terminal box 1 and screw holes 8a, 8b for fixing the terminal box 1 to the ceiling wall surface.

FIG. B shows the ventilation fan 13 and its suspension frame 9. The suspension frame 9 is a U-shaped left and right side piece 9a, 9b, and the center body of the ventilation fan 13 is supported by a support pin p. It is to be grasped, and for fixing, an arcuate slit s is bored in the side piece, and the slit s is fixed to the central body by using a locking pin 14. Therefore, the ventilation fan 13 can be fixed such that the blowout nozzle port 13a is at a constant inclination angle in the range of 90 ° vertically.

The ventilation fan 13 is a commercially available product having an axial fan driven by an electric motor in a cylinder of a fixed length, and 13b is an air blow port to which a wire mesh is attached.

In the present invention, a slit 15 for engaging with the engaging fitting 5 attached to the terminal box 1 is formed in the central portion of the upper surface 9c of the suspension frame 9, and the slit 15 is provided. A through hole 16 into which the fastening bolt 7a is inserted from the arcuate slits 7a and 7b formed in the lifting frame 9 sandwiching the pin is provided. In the drawing, reference numeral 17 is a lead wire of the electric motor, which is provided along the side surface of the suspension frame 9 so as to extend upward, and its tip is fitted to the connector female 3 in the switch case of the terminal box 1. A connector male 18 for mounting is attached.

FIG. 2 is a usage diagram, in which the terminal box 1 according to the present invention is installed together with other electric wiring on the ceiling board 10 during the construction work, and the terminal thus installed is installed. A suspension frame 9 with a ventilation fan suspended is appropriately attached to the box 1, that is, the engaging fitting 5 of the terminal box 1 is fitted into the slit 15 on the upper surface of the suspension frame 9 and engaged. The bolts 6a from the arcuate slits 7a and 7b are respectively inserted into the corresponding through holes 16 and the lower portions thereof are screwed and fixed by the nuts 6b. At the time of fastening, the ventilation nozzle 13 is fastened so that the direction of the blowout nozzle port 13a is in the desired direction. This is done by appropriately changing the tightening position of the screw 14. The male connector 18 is inserted into and engaged with the female connector 13.

[0010]

[Effect of device]

 The present invention is configured as described above, that is, the ventilation fan 13 and the terminal box 1 are separated from each other, and the terminal box 1 can be used together with ceiling work and electrical work. Therefore, the workability is excellent, and the subsequent mounting work can be simplified together with the wiring work. It should be noted that the ventilation fan can be efficiently attached and detached at the position of the terminal box for maintenance and replacement.
