JPS62132101A - Corrosion depth judging jig of lp gas container - Google Patents

Abstract

PURPOSE:To make it possible to cope with many kinds of LP gas containers, by making it possible to easily re-adjust an indicator to zero scale even if the radiuses of curvature of the mirror plate parts of the LP gas containers differ. CONSTITUTION:In a configurational part approximate to a corroded mirror plate part 4, if a push rod 20 is pushed to the direction shown by an arrow R while three support legs 23 hold a main body 1 so as to be contacted with the mirror plate part 4, the inside 21a of a hook 21 pushes a lever 13 to move the same in a circular arc state. Therefore, a lever 8 also moves in a circular arc state by the frictional resistance of a seat plate 12 but impinges against a stopper 27 on the way to be stopped. However, if the push rod 20 is further pushed, sliding is generated and only the lever 13 moves. Next, if the push rod 20 and the hook 21 are returned to their initial positions by utilizing the repulsive force of a compression coil spring 22, the inside of the hook 21 allows the lever 13 to move to the direction shown by an arrow S in a circular arc state. At this time, the end part of a lever 6 cooperated through a lever 8, a pin 9 and a fulcrum shaft 5 presses a pin 3 to the side of the mirror plate part 4. Hereupon, the circular arc movement of the lever 8 stops but the lever 13 continues circular arc movement by a sliding phenomenon and stops along with the hook 21 to set the position of an indicator 17 at this time to a zero scale.

腐蝕部（ハ）の深さを判定できる。Also, the movement and position of the lever (6) at this point has no purpose. Next, using the reaction force of ) on the compression coil spring,
When the push lever (20) and the hook 0υ are returned to the cut-off position (the end of the 7-knob 0υ touches the inside of the main body (1)), the inside (21b) of the hook 01) will move the lever (13) toward the arrow (S).
) direction. At this time, the lever (6) is interlocked via the lever (8), pin (9), and fulcrum shaft (5).
The end of the pin (3) presses against the end plate (4)
Projection dimension = Y). Then, the arc movement of the lever (8) stops, but due to the sliding phenomenon of the seat plate (12), the lever (8) stops moving in an arc.
13) continues to move in an arc until the hook eυ stops (the end surface of the hook eI hits the inside of the main body (1)). At this time, the scale position of the pointer α7) is the O scale (reference point). Next, if the main body (1) is moved so that the end of the pin (3) fits into the corroded part (c), the pin (3) will move into the corroded part (c) due to the effect of the tension coil spring (16). Depth dimension (X
). At this time, since the pointer αη also moves in the direction of the arrow (T), the depth of the corroded portion (c) can be determined by reading the amount with the scale plate (18).

Effects of the Invention According to the present invention, the radius of curvature of the LP gas container end plate changes (output). Even if the substitute dimension (Y) changes), the pointer can be easily readjusted to the 0 scale (reference point), so it can be used with many types of LP gas containers. It can also be used to approximate the depth of corrosion on curved surfaces other than LP gas containers.
