Claims

[Scope of Claim for Utility Model Registration] (1) In a removable clamp with a connecting knob that uniformly tightens the entire circumference of a flange of a vacuum system piping, a bendable clamp body 1 that tightens the flange portion. The configuration is a metal U-shaped clamp block body 2 for fixing the bellows and flange, a screw with a knob for tightening 3, a U-shaped clamp block 6 for fixing the flange, and a metal joint plate 4. It is fastened with joint pins 5 and 7, and a removable stopper block 8 is attached to the inside of the clamp block body 6, and an adjustment nut 9' is attached to a threaded stopper 9 made of metal and round rod-shaped. A U-shaped clamp block body 12 for fixing a flange to be screwed and then connected is fastened to a connecting metal joint plate 10 using joint pins 11 and 13, and a U-shaped clamp block body 12 to be connected to the clamp block body 12 is secured. A removable stopper block 17 is attached to the inner side of the clamp block body 16, a stopper receiving hole 18 is provided inside the block, and the block body 16 is connected to the joint plate 14 and the joint pins 15, 19.
A U-shaped clamp block body 22 for fixing a flange, which is provided with a receiving screw portion 23 for connection with the clamp block body 16, is secured by a joint plate 20 and joint pins 21, 24, and the entire body is bent freely. A clamp with a stopper for a vacuum system piping flange, characterized in that a screw with a knob for tightening the clamp block body is freely screwed into a receiving screw portion 23 of the clamp block body 22. (2) The clamp body 1 ' , which is constructed in the same manner as the refractably connected clamp body 1, uniformly tightens the entire circumference of both sides of the moving flange part like a bellows part. A metal stopper block 8 is attached to a removable stopper block 8 provided on the inside of a U-shaped clamp block body 6 for tightening the flange, which is connected to the clamp body 1 which tightens and fixes the entire circumference of the flange portion 5 through the clamp body 1. A threaded stopper 9 is screwed onto the base of the round rod-shaped body, and an adjustment nut screw 9' is provided on the stopper, and a clamp block 12 for connecting with the joint plate 10 is followed by a clamp block 16 for tightening the connecting flange. A U-shaped clamp block body 16 for tightening a flange is provided on the clamp body 1 ' opposite to the clamp body 1, which is provided with a stopper receiving hole 18 on its inner side, and is clamped and fixed to the flange 25 on the opposite side. The stopper 9 of the clamp body 1 is fitted and fixed into the stopper receiving hole 18 provided in the stopper block 17 which is detachably attached to the clamp body 1 . A stopper block 8 is attached to the mold clamp block body 6, and a stopper 9, which is a round bar-shaped metal body, is attached.
is inserted into the stopper receiving hole 18 of the main body 1 , and the bellows portion and both flanges are freely tightened and fixed by the block body 22 and the knob-equipped screw 3 of the clamp block body. Clamp with stopper for piping flanges.
