BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manifold block connecting mechanism.

[0002]

2. Description of the Related Art The inventor of the present invention has previously described in Japanese Patent Application No. 1-1.
No. 05461 proposed a manifold block connecting mechanism. This proposed manifold block connection mechanism has the advantage of connecting as many manifold blocks as the number of valves required, but there is a lack of consideration in connection workability. The connecting work is troublesome because it is inserted and removed, and the connecting fitting may be accidentally dropped and lost.

SUMMARY OF THE INVENTION An object of the present invention is to provide a manifold block connecting mechanism which can be easily connected.

[0004]

In order to solve the above problems, the present invention provides a manifold block connecting mechanism for connecting a plurality of manifold blocks on a connecting surface, wherein the manifold block is connected to one connecting surface.
Insert from the front of the manifold block along the connecting surface.
The rotatable connecting rod, and the other connecting surface with an engaging portion.
The connecting rod can be engaged with and disengaged from the engaging portion by rotation.
Equipped with engaging protrusions, which allows the connecting rod to rotate in a predetermined direction.
Engage the engaging projections with the engaging parts to connect the manifold block.
Tie and rotate in the opposite direction to engage the engagement protrusion with the engagement part
Is characterized by releasing the connection of the manifold block .

Further, in order to solve the same problem, it is preferable that the engaging projection has an engaging surface for pressing the connecting surfaces to each other by engaging with the engaging portion.

Further, to solve the same problem, the manifold block includes a connecting rod, a slidable connecting pin, an engaging portion, and an engaging hole with which the connecting pin engages. However, it is preferable to include an engaging protrusion and an operating portion of the connecting pin.

Further, in order to solve the same problem, it is preferable that the connecting pin has an engaging surface for pressing the connecting surfaces to each other by engaging with the engaging hole.

[0008]

When the connecting surfaces of the pair of manifold blocks are brought into contact with each other and the connecting rod is rotated in a predetermined direction, the engaging protrusions of the preceding manifold block engage with the engaging portions of the next manifold block. Then, the manifold blocks can be connected, and when the connecting rod is rotated in the opposite direction, the engagement between the engaging protrusion and the engaging portion is released, and the connected manifold blocks can be separated. The connection and disconnection of the manifold block can be performed on the front surface of the manifold block, so that workability is good, and the connection and disconnection can be performed even if a valve is installed on the manifold block, if necessary.

Further, since the connecting surfaces are pressed against each other by the engaging surfaces provided on the engaging protrusions, the connection is reliable and the fluid leakage at the connecting portion can be prevented.

Further, the connecting rod engages the engaging projection with the engaging hole, and the connecting pin engages with the engaging hole, and the engaging surfaces of the engaging projection and the connecting pin press the connecting surfaces against each other. Therefore, the connection of the manifold blocks becomes stronger.
