Abstract

<P>PROBLEM TO BE SOLVED: To provide a joining member for welding rods (silver solder/phosphor copper solder specified in JIS) which are shortened and difficult to use. <P>SOLUTION: Two welding rods (shortened or regular-sized) are inserted into both ends of the joining member (shown in Fig. 1) whereby a long welding rod which is usable is formed. The joining member (shown in Fig. 1) is melted together with the welding rods. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

この発明は、短く使いづらくなった溶接棒２本を、部材（図１・図２）の接続部材により無駄なく使えるようにした。According to the present invention, two welding rods that are short and difficult to use can be used without waste by connecting members of the members (FIGS. 1 and 2).

この発明は、部材（図１）の両方から溶接棒を差込み使用できるものとした。In the present invention, a welding rod can be inserted and used from both members (FIG. 1).

この発明は、現在の溶接棒と同じ材質、同等の加工により溶接棒本体と一緒に熔解していくので、従来通りの使用ができる。Since the present invention is melted together with the main body of the welding rod by the same material and the same processing as the current welding rod, it can be used as usual.

部材（図１・図２）は、一度差込んだら抜けにくいものとする。The member (FIGS. 1 and 2) is assumed to be difficult to remove once inserted.

従来の定尺溶接棒は、熔解していくに連れ短くなる。その短くなった溶接棒はバーナー（図３−Ｄ）の火力（図３−Ｅ）により、熱を有しているので、腕手が熱くなり溶接棒を掴んでいられなくなる。Conventional welding rods become shorter as they are melted. Since the shortened welding rod has heat due to the heating power (FIG. 3-E) of the burner (FIG. 3-D), the arm is heated and cannot hold the welding rod.

短くなった溶接棒は、自ら熱を加え接続し長いものとするか、工事現場などの状況により、紛失してしまったり捨ててしまうのが現況。Shortened welding rods are either lost by heating or connected, or are lost or discarded depending on the construction site.

そのために、次のような欠点がある。Therefore, there are the following drawbacks.

工事現場などにおいて、短い溶接棒２本を自ら熱を加え接続し、時間がかかる。At construction sites, it takes time to connect two short welding rods by applying heat.

定尺の溶接棒に対して、約２割が短く使いずらくなってしまう。溶接棒は工事現場の状況によって、短い溶接棒が紛失してしまったり、知らない間にゴミとなる事が多々ある。About 20% of the standard welding rod is short and difficult to use. Depending on the situation of the construction site, the short welding rods are often lost or become trash without your knowledge.

価格的にも、割高な溶接棒を現場作業中に少しでも無駄なく使用したいという思いがあり、腕手が熱くなる時も、「ガマン」しながらの作業となる事が多々ある。In terms of price, there is a desire to use expensive welding rods without any waste during on-site work, and even when the hands become hot, there are many cases where work is done while being “gaman”.

以上の事から、冷媒管を接続する事が多い工事現場では、作業時困難を強いられていた。
本発明は、これらの欠点を解決する為になされたものである。From the above, at construction sites where refrigerant pipes are often connected, it has been difficult to work.
The present invention has been made to solve these drawbacks.

短くなった溶接棒の先端に部材（図１）の片方を差込み、もう片方に定尺溶接棒又は、短い溶接棒を差込み、新たに長い溶接棒となり、再び従来通りの使用ができる。One of the members (FIG. 1) is inserted into the end of the shortened welding rod, and a standard welding rod or a short welding rod is inserted into the other end to form a new long welding rod, which can be used as usual again.

部材（図２）を作業時使用し、部材（図２）が短くなった時、片側には、部材（図１）と同じ効果を持つ接続口があるので、そのまま定尺部材（図２）を接続させ、長い溶接棒となり、接続して使用する。
本発明は、以上の構成からなる、接続部材である。When the member (Fig. 2) is used during work and the member (Fig. 2) is shortened, there is a connection port on one side that has the same effect as the member (Fig. 1), so the standard member (Fig. 2) Are connected to form a long welding rod, which is used by connecting.
This invention is a connection member which consists of the above structure.

この発明は、部材（図１・図２）を使用することにより、短くなった溶接棒が紛失したり、ゴミとなる事が少なくできる。In the present invention, by using the member (FIGS. 1 and 2), it is possible to reduce the loss of the shortened welding rod or the dust.

ワンタッチで接続できるので、火を使っての作業中、容易に長い溶接棒となるので、安全かつ経済的とすることができる。Since it can be connected with one touch, it becomes a long and easy welding rod during work using fire, making it safe and economical.

部材（図２）は、これを使用する事で短くなった時に、同じ部材（図２）を差込み使用することが可能なので、部材（図２）を使用することで部材（図１）を最小限持つ事で済まされる。When the member (Fig. 2) is shortened by using this, the same member (Fig. 2) can be inserted and used. Therefore, the member (Fig. 2) can be minimized by using the member (Fig. 2). It is done by having a limit.

以下、本発明の実施の形態を図１〜図５に基づいて説明する。Hereinafter, embodiments of the present invention will be described with reference to FIGS.

部材（図１）のイとハ両側に溶接棒を差込み、短く使いづらい溶接棒が従来通り、長い溶接棒となる。バーナー（Ｄ）・火力（Ｅ）により、腕手（Ｆ）が長い溶接棒によって、離れる事が出来た（図４）。The welding rods are inserted on both sides of the members (FIG. 1), and the welding rod which is short and difficult to use becomes a long welding rod as usual. With the burner (D) and firepower (E), the arm (F) could be separated by the long welding rod (Fig. 4).

部材（図２）の溶接棒は、現在の定尺溶接棒の片方に、部材（図１）と同様の目的がはたせる加工をした事によって、部材（図１）を持ち歩く事なく容易に接続できる。The welding rod of the member (FIG. 2) can be easily connected without carrying the member (FIG. 1) by processing one of the current standard welding rods to achieve the same purpose as the member (FIG. 1). .

部材（図１・図２）は、現在の溶接棒と同じ材質、同等の加工がされているので、溶接棒と一緒に熔解していく（図５）。Since the members (Figs. 1 and 2) are made of the same material and the same processing as the current welding rod, they are melted together with the welding rod (Fig. 5).

本発明の斜体図である。It is an italic view of the present invention. 本発明の斜体図である。It is an italic view of the present invention. 現在の溶接作業状況図である。現在の接続作業では、溶接棒（１）が定尺の物であり、熔解されるにつれて、短くなっていく。それと同時に腕手（Ｆ）が、火力（Ｅ）により熱くなる。It is a current welding work situation diagram. In the current connection work, the welding rod (1) is a standard object and becomes shorter as it is melted. At the same time, the arms and hands (F) are heated by the heat (E). 本発明使用中の溶接作業状況である。短くなった溶接棒（１−１）を継続使用する事で、火（Ｅ）に対して、腕手（Ｆ）がとても近く熱い状態となる。そこで、接続部材（２）を使用することで、火（Ｅ）にまた一定以上の距離をとるようになる。It is the welding work situation in use of this invention. By continuing to use the shortened welding rod (1-1), the arm (F) is very close to the fire (E) and becomes hot. Therefore, by using the connecting member (2), the fire (E) takes a certain distance or more. 本発明使用中の溶接作業状況である。接続部材（２）は、溶接棒（１）と同じ材料を使用し、同等の加工がされているので、接続部材（２）そのものが熔解され、熔解された溶接棒と同じ効力をあらわす。It is the welding work situation in use of this invention. Since the connection member (2) uses the same material as the welding rod (1) and is processed in the same manner, the connection member (2) itself is melted and exhibits the same effect as the molten welding rod.
