The present invention will be described below based on embodiments with reference to the drawings.

〔Example〕

1 and 2 are a front view and a side view showing a front mechanism of a high-pressure container to which the present invention is applied.

The high-pressure container 1 consists of a container body 2 having an opening on the front, and a door 3 that closes the opening. The door part 3 is supported by the container body 2 by a hinge 4, and the door part 3 is provided with an operation handle 5, and when the handle is rotated, the radial rods 6, 6, . The tips thereof are fitted into door tightening members 7, 7, . . . provided at positions facing each of the rods on the periphery. Also,
Pressurized heated steam is introduced through pipe 8 and discharged as drain through pipe 9. High pressure vessels having front features such as those described above are well known.

The present invention provides a front mechanism for such a high-pressure vessel, which has the following features.

First, as shown in FIG.
0 with a pin 11, and is connected with a pin 13 to another bracket 12 standing from the door 3 (more specifically, the door front plate 3a) near the center thereof, and then It is provided with a lever 15 that is slidably fitted into a rod 14 that extends from the door 3 near the end.

FIG. 4 is an enlarged explanatory diagram of the rod 14.
The tip of the lever 15 is formed into a screw, and a nut hinged to the screw serves as a stopper 16 for preventing the lever 15 from being removed from the rod body 14. Further, a compression spring 17 is fitted to the rod 14 on the left side of the lever 15. This spring 17 normally acts to press the lever 15 against the stopper 16, but when a large force is applied to the lever 15 to the left, it contracts to allow the lever 15 to move to the left.

Now, when the door part 3 is lightly closed to the position shown in FIG. When the radial rod 6 is inserted into the door tightening member 7 and tightened for durable closure, the door portion 3 does not swing around the pin 11, but moves forward uniformly as a whole. That is, when the door section 3 is tightened, the amount of movement of the bracket 12 and pin 13 held by the door section 3 and the amount of movement of the rod 14 are the same. On the other hand, since the lever 15 swings around the pin 11, the amount of movement of the portion of the tip of the lever 15 that is fitted into the rod 14 is equal to the amount of movement of the tip of the lever 15.
The amount of movement is greater than the amount of movement of the part that engages with 3. Therefore, if the ends of the rod 14 and the lever 15 are rigidly fixed, an unreasonable force will be applied to the lever 15 and the lever 15 will be damaged. In the present invention, the lever 15 is made slidable relative to the rod 14.

As mentioned above, in the front mechanism according to the present invention, when the operating handle 5 is rotated, the door tightening members 7, 7, . . .
Each of the radial rods 6, 6, . That is, the handle 5 is held in a moving sleeve 18, which has an internal thread and is connected to the threaded shaft 1.
The screw shaft 19 is screwed into a cap nut 20 fixed to the door plate 3a of the door portion 3 and fixed thereto. Also provided is a thrust 21 which moves axially together with the moving sleeve 18 but is prevented from rotating. Therefore, when the handle 5 is rotated, the movable sleeve 18 is also rotated, whereas since the screw shaft 19 is stationary, the movable sleeve 18 moves in the axial direction, and the thrust 21 also moves in the axial direction.

In the present invention, the thrust 21 has an inclined surface 22 that engages the end edge of the radial rod 6, and this inclined surface 22
A thrust pin 24 is provided parallel to the radial rod 6 and passes through the perforation 23 near the end of the radial rod 6. When the thrust 21 moves in the direction of arrow B, the inclined surface 22 pushes the edge of the radial rod 6 and moves the radial rod 6 in the direction of arrow C, causing the tip of the radial rod 6 to fit inside the door tightening member 7. let Conversely, when the thrust 21 moves in the opposite direction of arrow B, the thrust pin 24
pulls back the radial rod 6, and the radial rod 6 moves in the direction opposite to the direction of arrow C and separates from the door tightening member 7. Although only one radial rod 6 is shown in FIG. 5, in reality, all the radial rods 6, 6, . The door part 3 is fitted inside the attachment members 7, 7, .

Another important feature of this invention is the radial rod 6
The contact portion between the door tightening member 7 and the door tightening member 7 is formed on the inclined surfaces 26 and 27. That is, the frame plate 3 of the door part
When pressing b against the seal 25 to seal it,
The line of action of the tightening force acts in the direction of arrow A at the tip of the radial rod, that is, toward the frame plate 3b. In such a structure, compared to a structure in which the line of action of the force on the frame plate 3b is parallel to the frame plate, no unreasonable force is applied to the tip of the radial rod.

[Effect of idea]

The present invention has the above configuration, and the tip of the lever that forms the hinge is slidably fitted to the rod that stands up from the door, so that the lever and the rod are firmly connected. Compared to the conventional structure in which the door is connected, when the door is closed, no excessive force is applied to the lever, which significantly reduces the chance of damage to the hinge.
In addition, the thrust, which reciprocates in the axial direction as the operating handle is rotated, is provided with an inclined surface that engages with the edge of the radial rod, and a thrust pin that passes through the perforation near the end of the radial rod parallel to the inclined surface. Since the radial rods are pushed outward in the radial direction by using a thrust pin, there is no unreasonable force on the radial rods compared to the conventional thrust pin that moves the radial rods both outward and inward in the radial direction. It has the advantage that it does not apply stress, is difficult to deform, and is difficult to break.Furthermore, the contact area between the radial rod and the door tightening member is formed on an inclined surface where the line of action of force acts toward the door frame plate. Therefore, it is an extremely useful device that has many advantages, such as not causing a large bending stress at the tip of the radial rod and eliminating the drawback that the tip of the radial rod is easily bent in conventional devices.
