ボルト２の締付けを隣接する密閉容器６間で行なわなけ
ればならないため、密閉容器間寸法を大きくとらなけれ
ばならないという問題点があつた。The conventional bellows body has the flange mounting holes as described above.
4c, the tie rod tightening hole 4d is provided outside the bellows 4a, so the bellows must be fixed and the bolts 2 of the tie rod portion must be tightened between the adjacent closed containers 6, so the dimension between closed containers must be reduced. There was a problem that it had to be taken big.
この考案は上記のような問題点を解消するためになされ

とを目的とする。The present invention has been made to solve the above-mentioned problems.The bellows can be fixed and the tie-rod part can be tightened from within the closed container, and the distance between the adjacent closed containers can be reduced. The purpose is to obtain a bellows.
この考案に係るベローズは、ヒダ状の伸縮性金属の両端
内径側にリング状の厚板をはめ込み、気密溶接をしてフ
ランジとし、このフランジに取付け用穴及びタイロツド
締付け用穴を設けたものである。The bellows according to the present invention is one in which ring-shaped thick plates are fitted on both inner diameter sides of a foldable stretchable metal, airtightly welded to form a flange, and this flange is provided with a mounting hole and a tie rod tightening hole. is there.
この考案におけるベローズは、フランジ取付け用穴、タ
イロツド締付け用穴がベローズより内径側にあるため、
密閉容器側から作業できることにより隣接密閉容器間寸
法の縮小化ができる。In the bellows in this invention, the flange mounting hole and the tie rod tightening hole are on the inner diameter side of the bellows.
By being able to work from the closed container side, the size between adjacent closed containers can be reduced.
以下、この考案の一実施例を図について説明する。第１

て一体になされる。An embodiment of the present invention will be described below with reference to the drawings. First
In FIG. 2 and FIG. 2, 1 is a bellows main body, 1a is a bellows, 1b is a flange, 1c is a flange mounting hole provided in this flange 1b, and 1d is a tie rod tightening hole also provided in this flange 1. . The flange 1b is fitted into the bellows 1a on the inner diameter side and welded to the bellows 1a to be integrated.
従つて、上記穴1c、1dはいずれもベローズ1aより内径側

トは気密容器６の内部で行うことができ、隣接気密容器
の間隔を広くする必要はなくなる。Therefore, the holes 1c and 1d are located on the inner diameter side of the bellows 1a, and the tightening of the tie rod tightening bolt 2 as shown in FIG. 3 or the flange mounting bolt 5 as shown in FIG. In the case of tightening, the bolts can be applied inside the airtight container 6, and it is not necessary to widen the space between the adjacent airtight containers.
なお上記実施例では、ベローズ１を列盤される各々の密

トをベローズ内から行なうようにすれば、密閉容器のど
ちらか一方向から作業できる。In the above embodiment, the bellows 1 are fixed from the inside of each hermetically-sealed container, but if one of the fixing bolts is carried out from inside the bellows, the work can be performed from one direction of the hermetically-sealed container. it can.
以上のようにこの考案によれば、ベローズを密閉容器内
から固定、締付けができるように構成したので、ベロー
ズ本体の厚みがうすくでき、隣接する気密容器間隔の縮
小化がはがれる効果がある。As described above, according to the present invention, since the bellows can be fixed and tightened from the inside of the closed container, the thickness of the bellows main body can be thinned, and there is an effect that the interval between the airtight containers adjacent to each other can be reduced.
