Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waterproof mounting device for lighting equipment, and more particularly to a waterproof mounting device for lighting equipment used in, for example, freezing and refrigerated warehouses.

Conventionally, this type of lighting equipment has been installed by fixing a lighting equipment body 17 with screws or the like to an exposed connection box 1 installed with piping on the ceiling of a refrigerated warehouse, etc., as shown in FIG. In addition, the connection to the power source was made by directly connecting the lead wire from the lighting fixture A and the power lead wire attached during plumbing work within the connection box 1. However, when installing lighting equipment or removing it for repair or replacement of parts in an environment of -30°C, such as in a refrigerated warehouse, the work is extremely inconvenient due to the use of cold protection equipment.

The purpose of the present invention is to solve these conventional drawbacks, and to provide a lighting device that makes it easy to attach and detach the device itself and connect it to a power source, even when installing or removing the lighting device using cold protection equipment, etc. Our objective is to provide waterproof mounting devices for

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the waterproof mounting device for lighting equipment of the present invention will be described in more detail with reference to preferred embodiments shown in the accompanying drawings.

2 to 4 show a waterproof mounting device for a lighting fixture according to an embodiment of the present invention. In FIG. 2 showing this embodiment, parts similar to those of the conventional lighting fixture and its mounting device shown in FIG.

The waterproof mounting device in this embodiment is a U-shaped mounting bracket that opens downward and is fixed with screws or the like to the bottom surface of an exposed connection box 1 that is connected to a conduit 2 installed on the ceiling of a cold storage warehouse or the like. Contains 4. Square holes 25 and 28 for locking are formed in the opposing side walls of the mounting bracket 4, respectively (FIG. 4). Also,
An opening that also penetrates the bottom surface of the connection box 1 is formed in the center of the mounting bracket 4. A cap-shaped waterproof packing 10 is fitted into the opening, and its flange portion 12 is tightly attached to the inner surface of the mounting bracket 4. The mounting base 6 is placed on top of the mounting base 6 and is fastened together to the mounting bracket 4 with bolts 11. A plate spring 8 is provided in the central recess 7 of the mounting base 6.
A receptacle 5 is fitted and attached to the receptacle. The bottom surface of this outlet 5 is exposed to the outside from the center of the mounting base 6 downward, and is provided with two outlets for receiving plugs, which will be described later.The terminal section on the top surface has one end connected to a power supply 3 and is connected to the other end of the lead wire 13 led out from the top of the waterproof packing 10.

A threaded portion 9 for screwing the connecting cap 24 onto the mounting base 6 is formed on the outer peripheral surface of the mounting base 6. Inside this connection cap 24, the plug 21 attached to the end of the lead wire 22 extending from the lighting fixture A is housed in a state where it is inserted into the outlet 5 fixed to the mounting base 6. A waterproof gasket 23 is also housed around the plug 21 so as to cover it in a watertight manner.

When the plug 21 is pulled out from the outlet 5 together with the waterproof packing 23, the mounting bracket 4, the packing 10, the mounting base 6, the outlet 5,
The main part of the connecting cap 24 constitutes a mounting structural member on the ceiling surface side.

On the other hand, the mounting structure member on the lighting fixture A side is a U-shaped hanging fitting 18 that is open upward and is fixed to the upper surface of the fixture body 17. As clearly shown in FIG. 4, this hanging fitting 18 is provided with a projecting piece 26 that is formed inward from the upper edge of one side wall and can be engaged with the square hole 25, and also has a projecting piece 26 that can be engaged with the square hole 25. is curved outward and downward to serve as a hook piece 27 for engaging and disengaging operation, and also has an engaging piece 29 on the side wall that can be engaged with the square hole 28.
is protruded inward by cut-and-raised edges.

To install the lighting fixture A using such a waterproof mounting device, first connect the plug 21 at the tip of the lead wire or cord 22 extending from the fixture body 17 via the bush 20 into the outlet 5, Next, after covering the waterproof gasket 23, attach the connecting cap 24 to the mounting base 6 so as to cover these.
The plug 21 is screwed on to surround the plug 21 in a watertight manner.
Thereafter, one protrusion 26 of the hanging fitting 18 fixed to the top surface of the instrument body 17 is attached to the square hole 26 of the mounting fitting 4.
or 28, hook the hooking piece 27 with your finger, lift it up, and press fit the other engaging piece 29 into the other square hole. As a result, the hanging fitting 18
is engaged with the mounting bracket 4, and thus the lighting fixture A is installed on the ceiling surface.

When repairing or replacing lighting fixture A, it is sufficient to remove it in the reverse order. That is, hold the hook piece 27 of the hanging bracket 18 and remove the engaging piece 29 from the square hole of the mounting bracket 4, and then remove the hanging bracket 18 and the mounting bracket 4.
Unlink with. Next, the connecting cap 24
is rotated and removed from the mounting base 6, the plug 21 is exposed, and this is pulled out from the outlet 5. As a result, all the parts connected to the lighting fixture A are separated from the mounting structure on the ceiling surface side. Note that 14 is a lamp, 15 is a ballast, and 16 is a transparent cover.

As described above, according to the waterproof mounting device for lighting equipment of the present invention, when installing a lighting equipment on a ceiling surface, the plug is inserted into the outlet, the waterproof gasket is covered, and the connection cap is attached to make the plug watertight. The hanging bracket that is attached to the fixture body can then be locked to the mounting bracket with one touch, making it easy to remove when installing the lighting fixture or repairing or replacing parts, even in adverse environments. can be done.
