Description

[Detailed description of the invention] The present invention mainly relates to a protective cover, commonly called a lamp guard, that is installed around a lighting equipment for mounting and lighting a reflective incandescent lamp or a reflective mercury discharge lamp, and particularly for lighting. This invention relates to an improvement in the tightening neck of the main body that is attached to the forehead of the instrument.

In recent years, due to the tightening of industrial safety and health regulations, it has become mandatory to install lamp guards on lighting equipment used at construction sites, etc., so the demand for lamp guards is rapidly increasing. The holder of the main body of the lamp guard that was used was attached to the main body by spot welding with sporato welders, so all the metal fittings and opening/closing fittings were attached to the main body by spot welding with sporato welders, so these welded parts could easily peel off or There was a drawback that rust formed in this part, causing corrosion and falling off.

Furthermore, as mentioned above, the conventional method involves welding the metal fittings, etc., so materials such as galvanized steel sheets, which are rust-proof and inexpensive, cannot be used.
Therefore, after welding is completed, the entire main body and mounting hardware must be painted, but this has drawbacks such as extremely low work efficiency, high contrast, and a high incidence of defective products.

The lamp guard according to the present invention is a completely new technology developed in view of the drawbacks of the conventional lamps.

To specifically explain one embodiment of the lamp guard according to the present invention with reference to figures, in Figs. It is a net that can be used.

Reference numeral 3 denotes a ring integrally attached to the rear end of the main body 1, and has a diameter such that the area around the front neck of a lighting device (not shown) can be inserted into the ring.

Part of this ring 3, as is particularly clear from FIG.
A bent portion 4 is formed by protruding in the axial direction with a height and width equal to the wall thickness and width of a fixing fitting to be described later, and a row line is provided in the center of this bent portion 4. A long cut groove a is bored from the center toward the center, and water holes are bored on both sides of the cut groove a.

Next, reference numeral 5 denotes a U-shaped fixing fitting which is folded in two and can be attached and fixed to the above-mentioned bent part 4, and a screw C into which a screw 6 can be screwed is passed through the center part of the fixing fitting, and the fixing fitting can be fixed. On both sides of the upper plate of the metal fitting 5, locking claws d which can be engaged with the water holes of the bent portion 4 are provided so as to project downwardly from the head.

In the assembly structure of the lamp guard according to the present invention, when the opening part of the fixing fitting 5 is placed against the bent part 4 of the ring 3 and the fixing fitting 5 is pushed into the bent part 4 in this state, the fitting 5 is engaged. retaining claw d
is inserted into the water hole, and the locking claw d and the water hole are engaged with each other, so that the fixing fitting 5 is fixed to this bent portion 4,
In addition, the screw 6 previously attached to the fixing fitting 5 is attached to the bent portion 4.
It is configured by being deeply inserted into the cut groove a of.

When attaching this lamp guard to a lighting fixture, insert the front neck of the lighting fixture into the ring 3 and then attach the fixing bracket 5.
The lamp guard can be firmly fixed to the lighting equipment by rotating the screw 6 so that its tip gradually protrudes, thereby tightening the neck and the ring.

In the lamp guard according to the present invention, a ring 3 is integrally attached to a main body 1, and a bent part 4 having a cut groove a and a water hole is formed in this ring 3, and this part is used to hold a fixing fitting 5. Since it is configured to stop, there is no need to attach mounting brackets or clamping brackets by spot welding as in the past, and it is possible to integrally mold the main body 1 when removing the brake, which improves work efficiency. There is no risk of the welding part peeling off or rust forming in this area and causing corrosion.Also, since there is no welding, galvanized steel sheets and other galvanized steel sheets can be used as they are, and there is no need for painting as is the case with conventional methods. Since the ring 3 is provided with bending parts 4 in the row direction, the inner surface of the fixing fitting 5 attached to this part is flush with the inner surface of the ring 3. Since the bent part 4 has a cut groove a, the screw 6 can be inserted into the fixing bracket 5 while remaining attached. A water hole is drilled in the bending part 4, and a locking claw d that descends toward the head is drilled in the upper plate of the fixing bracket 5, so that the fixing bracket 5 can be bent. When fitted into the portion 4, the water hole and the locking claw d are automatically and firmly fixed together, and the assembly structure is simple and durable.
