Manifold Block Din Rail Attachment {structure for installing manifold block to din rail}

The present invention relates to a DIN rail attachment structure for attaching a manifold block equipped with a pilot solenoid valve to a DIN rail.

The pilot type solenoid valve is a device for switching the flow path of the main valve according to whether or not a current is applied to the solenoid and is an essential device in an automated process. Such a pilot solenoid valve includes a solenoid to which a current is applied, a main valve to switch a flow path by a magnetic field generated by the solenoid, and a plurality of flow ports communicating with the flow path and communicating with a number of fluid supply pipes and fluid exhaust pipes. The components are installed in the manifold block.

However, the space in which the manifold block on which the pilot type solenoid valve is mounted is installed is often a narrow place where a large number of fluid supply pipes pass or a plurality of pilot type solenoid valves are used simultaneously.

At this time, at the ends of the inclined surfaces 37a and 37b, protrusions 38a and 38b slightly protruding downward are formed.

Hereinafter, a manifold block DIN rail attachment structure according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view showing a manifold block mounted with a pilot solenoid valve and a DIN rail attachment structure, and FIG. 2 is a state in which a manifold block equipped with a pilot solenoid valve is mounted on a DIN rail. 3 is a perspective view of the fixing member of FIG. 2.

First, a schematic pilot type solenoid valve 10 will be described. The solenoid 11 to which a current is applied, the main valve 12 for switching the flow path by a magnetic field generated by the solenoid 11, the flow path and It includes a plurality of flow path ports 13 communicated with and connected to the plurality of fluid supply pipes and the fluid exhaust pipe. The pilot solenoid valve 10 is mounted on the manifold block 15. The lower end of the manifold block 15 is formed with a plurality of screw holes (not shown) formed with a screw, and through holes 16 penetrating the upper and lower portions are formed at both sides.

The DIN rail attachment structure according to the present invention typically includes a DIN rail 20 installed in a structure having a narrow space, and a bracket 30 for attaching the manifold block 15 to the DIN rail 20. At this time, the bracket 30 is composed of a bracket body 31 and a fixing member 36 located inside the bracket body 31.

The DIN rail 20 is attached to a predetermined structure (not shown), and both edges are formed with first and second wings 21 and 22 bent in a '-' shape.

The bracket body 31, which is one of the components constituting the bracket 30, includes a main body upper portion 31a and a main body side portion 31b bent downward from both sides of the main body upper portion 31a.

In the main body upper portion 31a, a plurality of through holes corresponding to the screw holes of the manifold block 15 are formed, and in this embodiment, two through holes 32 are formed. The first bolt 17 coupled to the screw hole formed in the lower portion of the manifold block 15 passes through the through hole 32.

Moreover, the screw hole 33 in which the screw is formed in the inner peripheral surface is formed in the main-body upper part 31a between the through-holes 32. As shown in FIG. As the screw hole 33, a second bolt 18 penetrating through the through hole 16 of the manifold block 15 is screwed.

Each of the main body side portions 31b is provided with first and second grooves 34a and 34b into which the first and second wings 21 and 22 of the DIN rail 20 are fitted. At this time, the depth of the first groove 34a is formed deeper than the depth of the second groove 34b so that one of the first and second blades 21 and 22, for example, the first blade 21 is the first groove. After the fitting through the 34a, the remaining second blades 22 are fitted into the second grooves 34b. And the long hole 35 is formed in the substantially center of the main body side part 31b, and the projection 39 of the fixing member 36 mentioned later is pinched | interposed.

The fixing member 36 has a length slightly larger than the inner side of the first and second wings 21 and 22, and at each end thereof, as shown in FIG. 3, each of the first and second wings 21 and 22. Inclined surfaces 37a and 37b are formed in contact with the corners formed by?). At this time, protruding protrusions 38a and 38b slightly protruded downward are formed at the ends of each of the inclined surfaces 37a and 37b.

In the center of the fixing member 36, the protrusion 39 slightly protrudes outward. The protrusion 39 is elastically deformed when the fixing member 36 is inserted into the bracket body 31, and is inserted into the long hole 35. The fixing member 36 is not easily detached from the bracket body 31 by the projection 39 is inserted into the long hole 35.

Referring to the installation process of the DIN rail attachment structure of the above structure as follows.

First, the bracket body 31 is positioned below the manifold block 15 on which the pilot solenoid valve is mounted, and the first bolt 17 passes through the through hole 32 of the upper portion 31a of the main body. It is coupled to the threaded hole of the manifold block 15. The bracket body 31 is then firmly coupled to the manifold block 15. Here, the fixing member 36 is inserted into the bracket body 31 so that the inclined surfaces 37a and 37b face downward, so that the protrusion 39 is fitted into the long hole 35. The bracket body 31 is released after being assembled in advance at the factory.

Next, the manifold block 15 to which the bracket body 31 is attached is attached to the DIN rail 20 fixed to a predetermined structure. That is, as shown in FIG. 4, when the manifold block 15 is inclined at an angle, the first blade 21 is inserted into the first groove 34a and the second blade 22 moves in the direction of the arrow. The position corresponding to 34b).

Next, as shown in FIG. 5, when the manifold block 15 is moved to the right, the second blade 22 is fitted into the second groove 34b. At this time, since the depth of the first groove 34a is deeper than the second groove 34b, the first blade 21 is also the first groove in the state in which the second blade 22 is fitted in the second groove 34b. It becomes stuck in 34a, and it cannot become detached.

Next, the second bolt 18 is passed through the through hole 16 of the manifold block 15 and then screwed into the screw hole 33 of the upper portion 31a of the main body. When the second bolt 18 is turned more, the lower end of the second bolt 18 penetrates the screw hole 33 to press the fixing member 36 downward. Then, as the fixing member 36 moves downward, the inclined surfaces 37a and 37b press the corners of the first and second blades 21 and 22, whereby the manifold block 15 is connected to the DIN rail 20. To be attached. At this time, since the protrusions 38a and 38b of the fixing member 36 press the first and second wings 21 and 22 to the upper portion, the bracket 30 may be more firmly fixed to the DIN rail 20. To help.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.

As described above, according to the DIN rail attachment structure according to the present invention, the manifold block in which the bracket body is installed is tilted slightly at an angle to the DIN rail fixed to a predetermined structure, and then inserted into the first and second grooves to rotate the second bolt. By adhering to a DIN rail by this, the attachment process is very easy. This means that the attachment can be facilitated even if the space where the manifold block is installed is complicated or narrow. In addition, the bracket body is located below the manifold block so that the fluid supply pipe and the fluid exhaust pipe are not obstructed, thereby facilitating piping work.

In addition, since the screw hole and the through hole formed in the existing manifold block are used as it is, there is an effect that the manifold block does not need to be modified to adopt the DIN rail attachment structure of the present application.
