BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manifold block fixing device for fixing to a rail a desired number of manifold blocks arranged in series along a rail.

[0002]

2. Description of the Related Art A fixing device for a manifold block, which fixes a desired number of manifold blocks continuously arranged along a rail to a rail by a fixing block, is already known from, for example, Japanese Utility Model Publication No. 1-136779. There is. However, in the fixing device of the manifold block, since the two fastening bolts provided on the fixing block attach and detach these to and from the rail, not only is labor required for the attaching / detaching operation, but also two bolts are not required for one-side tightening. Since it is necessary to tighten the tightening bolts with a uniform force, tightening the bolts is troublesome.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a fixing device for a manifold block which can be easily attached to and detached from a rail.

[0004]

In order to solve the above-mentioned problems, the present invention is to fix a desired number of manifold blocks continuously arranged along a rail having flanges on both sides in the width direction to the rail by a clamp metal fitting. In the fixing device for a manifold block, the clamp metal fittings include a clamp main body having left and right legs straddling the width direction of the rail, and a clamp main body provided with a fixing hook that engages with one of the flanges on one leg. A pressing plate that is vertically movably inserted between the hook plate, a hook lever that has a movable hook that engages with the other of the collar parts and is pivotally supported by the clamp body, and is approximately at the center in the width direction of the rail. A fastening bolt screwed to the hook lever is provided, and the fixed hook and the movable hook, and the holding plate that moves by the rotation of the fastening bolt hold the collar portion to hold the manifold. It is characterized in that to fix the block to the rail.

In order to solve the same problem, it is preferable to provide a spring for urging the movable hook in the opening direction.

[0006]

[Operation] When the fixed hook of the clamp metal fitting is engaged with one of the flange portions of the rail, the clamp metal fitting is mounted on the rail from above, and the tightening bolt is tightened, the hook lever rotates to move the movable hook to the flange portion. Since the pressing plate is pressed toward the rail while rotating to the position where it can be engaged with the other, the fixed hook and the movable hook and the pressing plate hold the flange portion, and the manifold block is fixed to the rail by the clamp metal fitting. It If this operation is performed in reverse, the clamp fitting and the manifold block can be removed from the rail.
Therefore, since the clamp fitting can be attached to and detached from the rail with one tightening bolt, the operation of attaching and detaching the clamp fitting for fixing the manifold block to the rail is easy. Further, the tightening bolt presses the pressing plate at the approximate center in the width direction of the rail, so that the tightening force becomes uniform and partial tightening can be prevented.

Furthermore, since the movable hook is urged by the spring in the opening direction, it is easier to attach / detach the clamp fitting to / from the rail.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of the present invention.
A rail 1 having flanges 1a and 1b on both sides in the width direction, and a manifold block 2, which is continuously provided along the rail 1.
.. and end plates 3 and 3 and clamp covers 4 and 4 attached to both ends of the clamp cover 4, and clamp fittings 5 to be described later are attached to the clamp cover 4.

Like the known manifold block, the manifold block 2 is provided with a supply flow path, a discharge flow path (not shown) and output ports A and B, which communicate with each other by connecting them, and these flow paths and ports are respectively Manifold block 2
Individually communicating with the corresponding port of the valve 6 installed in
The supply flow path and the discharge flow path individually communicate with the supply port P and the discharge port R of the end plates 3 and 3 (see FIG. 2). Although not shown, the manifold block 2 may be provided with a fixed hook, which will be described later, that engages with the collar portion 1a and an abutting portion that abuts against the collar portion 1b, like the clamp fitting 5.

The clamp cover 4 has a recess whose bottom and front are open, and the clamp metal fitting 5 mounted in this recess.
The clamp body 8 is formed by bending a metal plate or the like in an inverted U shape, and has legs 9a, 9 straddling the rail 1 in the width direction.
a and 9b, 9b (only one of which is shown) has an inverted U-shape in a side view, and the fixed hooks 10, 10 that engage with the collar portion 1a are attached to the tips of the legs 9a, 9a.
Contact portions 10a, 10a for contacting the collar portion 1b are formed at the tip of b, respectively, and the holding plate 11 bent in an inverted U-shape has the end portions 11a, 11a having legs 9a, 9a and 9b, 9
It is inserted in the clamp body 8 so as to be movable in the vertical direction by being guided by the guide b. The hook lever 14 pivotally attached to the clamp body 8 by the pin 13 has bent portions 14a, 14a bent in a U-shape when viewed from the front, and an extended portion 14b substantially orthogonal to the bent portion 14a, 14a
Movable hooks 15 and 15 that engage with the collar portion 1b are formed at the tip of the movable hook 15, and a tightening bolt 16 is screwed to the extension portion 14b.
Is urged to open. In addition, tightening bolt 16
Is screwed to the extension portion 14b so that the movable hooks 15 and 15 are positioned substantially at the center of the rail 1 in the width direction when the movable hooks 15 and 15 are rotated to the position where the movable hooks 15 and 15 can be engaged with the flange portion 1b.
a is the center hole 19 of the clamp body 8 and the clamp cover 4.
And 20 to project above the clamp cover 4.

In the above embodiment, a desired number of manifold blocks 2, ... And end plates 3, 3 are continuously provided in the longitudinal direction of the rail 1, and then the fixing hook 10 of the clamp fitting 5 attached to the clamp cover 4 is provided. , 10 is engaged with the collar portion 1a of the rail 1, and the clamp metal fitting is rotated from above toward the rail around this engaging portion, the contact portion 10a,
10a abuts on the flange portion 1b, and the rail 1 is positioned (see FIG. 1A). In this case, since the movable hooks 15, 15 are urged by the spring 17 in the opening direction, the clamp fitting 5 can be easily positioned with respect to the rail 1. Next, when the tightening bolt 16 is rotated in a predetermined direction, the tip of the bolt 16 presses the pressing plate 11 to move it downward in the drawing, and the extension portion 1 of the hook lever 14 is moved.
4b is moved upward, so that the fixed hooks 10, 10 and the movable hooks 15, 15 and the holding plate 11 hold the collar portions 1a, 1b, and the manifold blocks 2, ... (See FIG. 1B). When removing the manifold blocks 2, ..., From the rail 1, the above operation may be performed in reverse.

Since the clamp fitting can be fixed to the rail 1 by the single tightening bolt 16, the above-mentioned attaching / detaching operation is extremely simple. Also, the tightening bolt 16 is the rail 1
By pressing the pressing plate 11 substantially at the center in the width direction, the left and right tightening forces become substantially equal, so that there is no partial tightening.

[0013]

According to the manifold block fixing device of the present invention, since the clamp metal fitting for fixing the manifold block can be attached to and detached from the rail with one tightening bolt, the attaching and detaching operation is easy. Further, since the tightening force in the width direction becomes uniform, it is possible to prevent fluid leakage from the connecting surface of the manifold block due to one-side tightening.

Further, since the hook lever is biased by the spring in the direction in which the movable hook is opened, the clamp fitting can be more easily attached to and detached from the rail.
