Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a device for installing a fluorescent lamp having an increased safety explosion-proof structure.

(Prior art) When installing fluorescent lamps in equipment installed in places where hazardous materials are handled, such as gas station weighing machines, it is necessary to cover the fluorescent lamps with a protective cover to prevent fires caused by damage to the lamps. It has an explosion-proof structure with increased safety.

However, if such an explosion-proof structure is adopted, the globe must be removed each time a fluorescent lamp is replaced, which not only takes time and effort, but also causes problems such as not being able to replace the lamp in a confined space. .

(Purpose) The present invention was made in view of the above problem, and its purpose is to provide a device for installing fluorescent lamps with a new safety-enhanced explosion-proof structure that allows fluorescent lamps to be easily replaced even in narrow spaces. Our goal is to provide the following.

(Structure) That is, the present invention is characterized by a pair of holding members having a diameter into which a fluorescent lamp can be inserted and holding caps at both ends of the fluorescent lamp, and a transparent transparent lamp having both ends fixed by the holding members. Installation of a fluorescent lamp with an increased safety explosion-proof structure consisting of a light-sensitive fluorescent lamp enveloping member and a lid detachably attached to the holding member to hold the socket member connected to the fluorescent lamp in the axial direction is as follows: It's in the device.

Therefore, details of the present invention will be explained below based on illustrated embodiments.

Figure 1.2 shows an embodiment of the present invention,
Reference numeral 1 in the figure denotes a pair of adapters arranged to hold the base 21 portion of the fluorescent lamp 20, and a part of the semicylindrical outer peripheral surface 2 is used for attachment to a bracket 30 fixed to a device or the like. is formed downward as a surface 3, and a circular hole 4 is formed in the center through which a fluorescent lamp 20 with the largest diameter to be attached can be inserted.

By the way, on the inner surface of this adapter 1, that is, on the surface facing the other adapter 1, a comb-shaped guide portion 5 is integrally formed to protrude, and this inner surface, which is formed to have the same diameter as the circular hole 4, It is configured to expand outward by a tapered portion 5a formed at the tip, and to be inserted while being guided by the tapered portion 5a at the tip of the fluorescent lamp 20. A recess 6 is formed between the comb-shaped guide 5 and the outer peripheral surface 2, into which a ring-shaped backing 7 formed of an elastic material such as rubber and having a U-shaped cross section is fitted. The end portion of a transparent or translucent lamp protection cover 8 made of polycarbonate or the like coated with polyethylene is attached in an airtight manner. In addition, a threaded portion 9 for attaching a cap 11, which will be described later, is formed protruding on the outer circumferential surface of the adapter 1, and on the inner surface thereof, a hook 15 having four protrusions 16 at intervals of 906 is arranged at a pitch of 45°. Concave grooves 10 are provided at intervals of 45 degrees, and the grooves 10 can be positioned and fixed at 45 degrees.

On the other hand, a cap 1 that is screwed onto the threaded portion 9 of this adapter l
1 is formed in the shape of a cap nut, and holds the socket 15 airtightly between it and the adapter 1 via the backing 12. At the same time, the cord 17 is inserted through the hole 14 provided in the end plate 13.
It is configured to output to the outside. In addition, the code 1 in the figure
8 is a backing attached to the cap 21 of the fluorescent lamp 20;
It serves as an insertion guide when inserting the pin of the cap 21 into the socket.

In the embodiment described above, when it becomes necessary to replace the fluorescent lamp 20, the cap 11 is first removed from one adapter l, and the socket 15 is pulled out. This leaves the end of the adapter 1 in an open state, so pull out the old fluorescent lamp from the circular hole 4, insert the new fluorescent lamp 20 with the backing 18 attached, and connect the tip to the comb-shaped guide 5.
After fitting it into the other adapter 1 while guiding it,
It is combined with the socket 15 fixed there. And finally, match the socket 15 to the plug of the fluorescent lamp 20.
When the socket 15 pushes the other end of the fluorescent lamp 20 toward the other adapter 1, the socket 15 pushes the other end of the fluorescent lamp 20 toward the other adapter 1. At the same time, the cap 11 is airtightly clamped and fixed.

When the installation is completed in this way, the fluorescent lamp 20 is covered with the lamp holder 3C cover 8 installed between the pair of adapters 1, 1, and is airtightly placed between the caps 11.11 via the socket 15.15. Enclosed. Therefore, even if the fluorescent lamp 20 is damaged, sparks will not escape to the outside.
Further, since the guide 5 serving as a guide is formed in a comb-teeth shape, the fluorescent lamp 20 can illuminate the entire display section up to the end thereof.

Note that the base part is the same for each lot of fluorescent lamps, and in the embodiment of the present invention, the circular hole of the adapter is made larger, so that the adapter, socket, etc. can be installed by simply changing the length of the bracket and protective cover. can be used with fluorescent lamps of various wattages.

As described above, according to the present invention, a lid is detachably attached to a pair of base holding members that allow insertion of a fluorescent lamp, and the lid holds the fluorescent lamp and the socket member in the axial direction. As a result, the fluorescent lamp can be easily inserted and removed through the holding member by simply removing one lid, and the fluorescent lamp enveloping member and the fluorescent lamp are airtightly sealed by the pair of holding members. Therefore, this type of fluorescent lamp mounting member can be constructed extremely easily.
