Description

[Detailed Description of the Invention] This invention relates to a waterproof packing for lighting equipment that is easy to install.

Conventionally, as shown in FIG. 1, the waterproof packing A of a glove used in a lighting fixture is attached by adhering it to the inner upper surface of the flange C of the fixture body B with an adhesive D, or by attaching it to the inner upper surface of the flange C of the fixture body B, or Previously, a method was used in which the adhesive was inserted into the back side of the locking edge F provided at the top of the threaded portion E provided on the inner surface, but it was time-consuming to apply the adhesive, and the locking edge F was If the waterproof packing A is only inserted into the back side, the installation of the waterproof packing A will be incomplete.Especially when installing the lighting fixture G on the ceiling, first fix the fixture body B to the ceiling, and then fit the globe I from below using the screw groove H. At this time, the waterproof packing A fitted into the back side of the locking edge F of the instrument body B hangs downward, making attachment of the glove I complicated.

This idea improves the drawbacks of the conventional ones mentioned above.
The waterproof packing is previously adsorbed onto the inner upper surface of the instrument main body by an integrated suction portion, thereby fixing the waterproof packing to the instrument main body, thereby facilitating the installation of the glove.

This will be explained with reference to the embodiment shown in the figure. Reference numeral 1 is a disc-shaped instrument body having a protruding edge 2 on the periphery, and a threaded part 3 is carved on the inner surface of the protruding edge 2 of the instrument body 1. Further, a locking edge 4 is provided projecting from the upper part of the threaded portion 3.

Reference numeral 5 denotes an annular waterproof packing made of rubber or the like having concave grooves 6 on both the upper and lower surfaces. A dish-shaped suction part 7 is formed integrally with the protruding part 5 at a proper position, and the suction part 7 is pressed to be adsorbed to the side surface or internal top surface of the instrument body 1, and the waterproof packing 5 is attached to the instrument body. 1 and fix it.

Reference numeral 8 denotes a transparent cylindrical glove with a bottom made of resin or mold, and on the outside of the opening edge 9 of this glove 8 there is a threaded part 3 carved on the protruding edge 2 of the instrument body 1. Matching screw groove 1
0, this threaded groove 10 is screwed into the threaded part 3 of the instrument body 1, and the opening edge 9 of this glove 8 is attached to the waterproof packing 5.
The glove 8 is pressed into the instrument body 1 by being inserted into the groove 6 of the glove 8.

The one shown in FIG. 38 is another embodiment of the suction part, in which the suction part is integrally provided by protruding from both the upper and lower surfaces of the waterproof packing. When the waterproof packing 5 is attached to the side surface or the inner upper surface of the waterproof packing 5, there is no need to distinguish between the front and back sides of the waterproof packing 5 each time, and work efficiency is improved.

In this invention, the waterproof packing is fitted onto the inner upper surface of the instrument body that comes into pressure contact with the glove, and a suction part is provided integrally with this waterproof packing. To attach it to the top surface, simply press the suction part, and the suction force of the suction part will ensure that it will stick to the internal top surface of the device body, preventing the waterproof packing from hanging down unnecessarily and preventing it from hanging on the ceiling. When fitting the glove from below to the device body attached to the device, the glove can be easily attached to the device body, and since the waterproof packing is not placed on top of the glove, the glove can be attached smoothly. It has excellent effects.
