Description

Connector fixing device for air line mask

The present invention can be used by easily connecting an air line mask used to supply harmless air to workers at a site where harmful gas is generated, such as a semiconductor production line. The connector installed under the access floor and the floor panel of the access floor to reduce and shorten the construction period and to prevent product damage or the risk of operator jamming and falling when transporting and moving the product. It relates to a connector fixing device for an air line mask comprising: a casing embedded in and installed on an access floor in a corresponding shape; and fixing means for connecting and fixing the connector to the casing.

In general, at work sites such as semiconductor production lines where various harmful gases are generated or factories where harmful dust is generated, filtered air is used to provide a comfortable working environment and prevent respiratory diseases while making it easier for workers to breathe. A compulsory supply of air purifying masks is being used.

These air purification masks include a portable mask type equipped with an individual filtration filter and a built-in type used by connecting the mask to an air supply pipe installed in the field.

The portable mask type has the advantages of free movement of the operator and easy portability, but since it directly filters and supplies contaminated air including harmful gases generated in the field, there is a clear limitation in the air filtration function.

Most large-scale semiconductor production lines use built-in type air line masks.

On the other hand, the built-in type air line mask uses a connector to connect the worker's air line mask to the air supply pipe with a separate air supply pipe installed at the bottom of the site in advance.

As fresh air is constantly supplied forcibly through an air filtration device (or outside air supply device) installed separately outside and a blower means, it is very advantageous for fresh air supply and has the advantage that an air line mask can be selectively used only when necessary. .

On the other hand, in sites (air rooms) such as semiconductor production lines, for safety accident prevention and site cleanliness, a space is formed between the concrete floor of the building and the flooring material to embed and install various electrical wiring, gas, and fluid supply pipes, etc. A floor-type access floor is installed.

Such an access floor is constructed by installing a post on which a grid frame is supported on the upper part of the concrete floor and assembling a floor panel that matches the shape of the grid frame. It has the advantage that it can be easily connected to various wirings or pipes.

Accordingly, it is common that the above-described built-in type air line mask piping and connector are also installed in the space below the access floor.

However, due to the nature of the use of the air line mask, the connector installed on the general access floor frequently undergoes construction, relocation, change, and maintenance work. When work is required, the construction cost is excessive and the construction period is long.

That is, changing the installation location of the connector to suit the changing site layout, such as when setup, relocation, or utility hook-up of equipment installed on the on-site production line is required, or when additional connector construction is required. Alternatively, when additional installation is required, the conventional connector is in the form of being connected and fixed by a pipe and a pipe for supplying air, so it is difficult to construct, so there is a problem in that air increases and cost burden is very large.

In addition, the conventional connector is fixedly installed in a separate connector protection enclosure on the floor panel of the access floor, and the enclosure is provided in a form that protrudes above the horizontal surface of the floor panel. There is a problem in that safety accidents such as falling over frequently occur.

For reference, as a prior art related to a built-in type air line mask, there is a registered utility model No. 20-0355766 (registration date of June 30, 2004) "air supply mask with a regulator".

Accordingly, the present invention has been devised to solve the above problems,

By constructing the connector that connects the air line mask in the same way as the removal and assembly of the floor panel of the access floor, the installation, transfer, change, and maintenance of the connector is easy to reduce the construction cost and shorten the construction period, A connector for an air line mask comprising: a connector installed under the access floor; a casing embedded in the access floor in a shape corresponding to the bottom panel of the access floor; and fixing means for connecting and fixing the connector to the casing An object of the present invention is to provide a fixing device.

In the detailed description and claims of the invention related to other drawings, unless otherwise specified, the direction is specified and described according to this standard.

Hereinafter, a connector fixing device for an air line mask according to the present invention will be described with reference to the accompanying drawings.

1 [B] and AA of FIG. 1 which are plan views showing the state in which the cover panel 23 is opened in [A] of FIG. 1 and [A] of FIG. ' As shown in Fig. 2, which is a cross-sectional view, the connector fixing device for an air line mask according to the present invention is largely composed of a connector 10 installed under the access floor F, a bottom panel F1 of the access floor F, and A casing 20 installed in the same manner and a fixing means 30 for connecting and fixing the connector 10 to the casing 20 are included.

The connector 10 is connected to the air supply pipe (P) installed in the lower space of the access floor (F), and a connector capable of detaching the connecting hose (H) of the air line mask (not shown) worn by the operator. (11) is provided so that the operator can breathe uncontaminated air by connecting the air line mask, one or more, that is, a plurality of connectors 11 so that a plurality of workers can use the connector 10 Preferably, the figure shows a Y-type connector having two connectors 11 representatively.

Here, the air supply pipe (P) is connected to an external air filtering device (or outside air supply device; not shown) and a blowing means (not shown) and includes all types of pipes installed under the access floor (F). In the drawings, although it is shown as being installed on the top of the concrete floor surface (C), the type of pipe (main pipe, branch pipe, etc.), installation type (concrete exposure type, concrete embedding type, etc.) may vary. .

And it is preferable that the connector 11 of the connector 10 is provided with a quick coupling (not shown) that can be easily attached and detached in a male and female coupling structure with the connection hose H.

Also, although not shown in the drawings, the connector 10 may further include an on/off valve capable of controlling the air supply.

Next, the casing 20 has a shape corresponding to the floor panel F1 of the access floor F, and is embedded in the same manner as the floor panel F1 constituting the access floor F, and is vertically opened. A portion 21 is provided to ensure accessibility to the lower connector 10 .

In the drawing, the access floor F composed of the floor panels F1 having a typical rectangular shape is shown. Accordingly, the overall shape of the casing 20 also has a rectangular shape, and the shape of the casing 20 is also the floor panel. It may vary depending on the shape of (F1).

When the casing 20 buried in the access floor F is used in the same manner as the floor panel F1 in this way, the horizontal height of the floor panel F1 and the casing 20 is the same so that the upper part of the access floor F is used. Since the protruding portion is not formed, it is possible to prevent overturning due to jamming or the like.

And the casing 20 is provided with a cover panel 23 for opening and closing the hollow part 21, when using an air line mask, open the cover panel 23 to connect to the connector 10, and connect the air line mask When not in use, the hollow part 21 is closed with the cover panel 23 so that it can be used like the floor panel F1.

Unexplained reference numeral 22 denotes a stepped portion for seating the cover plate on the casing 20 .

Next, the fixing means 30 connects and fixes the connector 10 to the casing 20, and the connector 10 is provided at an appropriate height in the space between the access floor F and the lower concrete floor C. make it possible

To this end, the fixing means 30 of the present invention is

Both side coupling portions 31a coupled to both sides of the frame 20a of the casing 20 (refer to FIG. 4), and

The connector 10 is fixed, and the fixing plate 31 is bent into the space below the access floor F, and the fixing plate 31 is used to connect the both-side coupling parts 31a.

The both side coupling portions 31a are bolted to both sides of the frame 20a of the casing 20 and may be coupled to a lower surface of the frame or an upper surface of a stepped portion protruding inward from the frame.

And, the support part 31b is bent into a 'C' shape (or a 'U' shape similar) from the both side coupling parts 31a to the lower space of the access floor F, and the connector 10 is placed in the center. A fixing hole (not shown) for fixing is provided.

In this way, the fixing plate 31 formed in a similar 'C' shape (or a similar 'U' shape) has an original function of fixing the connector 10, and the support part 31b is coupled to the casing through both side coupling parts 31a. (20) by covering the hollow part (21) with a cover panel (23) to support the load applied from the upper part when used like a general floor, thereby reinforcing the rigidity of the casing (20) will have

In this case, in the drawings of the present specification, for convenience of understanding, the fixing plate 31 is shown in the upper portion of the air supply pipe (P), but it is mentioned above that the installation shape of the pipe may be different. Accordingly, when the support portion 31b of the fixing plate 31 has a structure supported by the lower concrete floor surface C, the bearing force of the casing 20 can be further increased.

In addition, the air supply pipe (P) and the connector (10) are connected by a flexible hose (12) to improve the construction convenience of the connector fixing device of the above structure.

That is, as the conventional connector is fixedly installed in the form of a pipe in the pipe for supplying air, in order to add or relocate the connector, the operator removes the floor panel around the enclosure provided with the connector and then enters the lower space of the access floor. Since it is necessary to enter and separate the piping and the connector, it is very difficult to work due to the narrow working space, which increases the amount of air and consequently increases the cost burden.

In the present invention, since the air supply pipe (P) and the connector (10) are connected by a flexible hose (12), the casing (20) is separated from the access floor (F) without the need to remove the surrounding floor panel (F1). Since the connector 10 can be connected and disconnected in this state, the conventional problems can be solved.

In this case, for fast fastening of the flexible hose 12, both ends of the flexible hose 12 and the coupling portion between the air supply pipe (P) and the connector 10 are provided with quick couplings ( The introduction of 12a) and 12b may further improve work convenience.

In addition, although not shown in the drawing, a connector (for example, a Y-type connector) having the above structure is introduced into the air supply pipe P, and the connector of the air supply pipe P and the connector of the casing 20 are connected. When connected with the flexible hose 12, it is possible to facilitate further expansion of the connector.

In addition, in order to use the connector 10, if the cover panel 23 is separated and used, a hole is perforated in the middle of the access floor F, so that the size of the hole can be minimized, the hollow part ( The cover panel 23 detachably attached to 21 includes a mounting portion 24 having a mounting hole 24a perforated therein, and is connected through a mounting hole 24a in a state where the cover panel 23 covers the casing 20 . Hose (H) to be fastened to the connector (10).

It is preferable that a cap member (not shown) capable of opening and closing the mounting hole 24a is provided in the mounting part 24 to close the mounting hole 24a while the connector 10 is not in use. In this case, the mounting part 24 ) and the cap member are more preferably provided so as to have the same horizontal height as the cover panel 23 .

On the other hand, the radius of use of the air line mask is substantially limited by the length of the connecting hose (H) connected to the connector (10). 20) When installed to be displaced within, it is preferable to further include a position displacement means 33 for this, since it is possible to widen the movement radius of the operator to ensure more free movement.

For this purpose, as shown in Figs. 3 and 4, the position displacement means 32 of the present invention is

Guide portions 32a formed along the longitudinal direction on the inner surfaces of both sides of the frame 20a of the casing 20;

It consists of a guide groove (32b) formed along both sides of the longitudinal direction of the support portion (31b),

The both side coupling portions 31a of the fixing plate 31 are slidingly coupled to the guide portion 32a, so that the front and rear positions of the fixing plate 31 are displaced,

As the connector 10 is slidably coupled to the guide groove 32b, the left and right positions of the connector 10 are displaced,

It may be possible to move the position of the connector 10 forward, backward, left, and right in all directions.

That is, the width of the support part 31b of the fixing plate 31 is formed to be the minimum width capable of fixing the connector 10, so that the fixing plate 31 and the connector 10 can move forward, backward, left, and right respectively. When the position of the connector 10 connected to the connection hose (H) according to the movement of the operator is displaced in the front, rear, left, right, all directions, it is possible to ensure the wide movement of the operator.

The positional movement of the connector 10 is made possible by connecting the connector 10 and the air supply pipe (P) with the flexible hose (12), as described above.

At this time, in order to enable the position displacement of the connector 10 through the position displacement means 32, the cover panel 23 has to be separated from the casing 20 and used, so it is inconvenient.

As shown in FIG. 4 to solve this problem, the cover panel 23 of the present invention is

The cover panel 23 includes an opening/closing type shielding means 25 that enables the use of the position displacement means 32 even in a state in which the cover panel 23 is assembled into the hollow part 21 of the casing 20 .

The opening/closing shielding means 25 of the present invention has a transverse opening/closing structure of the cover panel 23 itself.

The opening/closing type shielding means 25 forms the cover panel 23,

Left and right first shielding parts 251 connected to the four sides of the mounting part 24 in which the mounting holes 24a are formed, and capable of horizontal movement in the forward, backward, left, right and left directions along the frames 20a and 20b of the casing 20 and the front and rear second shielding parts 252, so that the position of the mounting hole 24a is displaced.

Horizontal and horizontal movement of each of the first shielding parts 251 and the second shielding parts 252 may be implemented in a sliding coupling structure.

That is, four shielding parts are connected based on the mounting part 24 to form the cover panel 23,

The left and right first shielding parts 251 are slidably coupled with both ends to the front and rear frames of the casing 20,

The front and rear second shielding part 252 and the mounting part 24 are slidably coupled with both ends of both ends to the inner ends of the left and right first shielding parts 251,

Through the opening/closing operation of the shielding parts 251 and 252, the mounting part 24 having the mounting hole 24a may be displaced on the hollow part 21 of the casing 20 together with the shielding parts.

Accordingly, the position of the connector 10 may be displaced and adjusted according to the movement of the operator even in a state in which the cover panel 23 is closed through the position displacement means 32 and the opening/closing type shielding means 25 .

In this case, when the shielding parts of a certain plate shape move horizontally in the horizontal direction, they interfere with the space below the bottom panel F1 around the connector fixing device. In order to prevent this,

The left and right first shielding parts 251 have a structure in which a plurality of first support pieces 251a that are slidably coupled to the front and rear frames 20b of the casing 20 are hinged to each other, and of the casing 20 The left and right frames 251b are provided with first draw-out holes 251b through which the first support pieces 251a pass to elevate and lower at the lower part of the casing 20,

The front and rear second shielding part 252 has a structure in which both ends of a plurality of second support pieces 252a slidably coupled to the inner end first support piece 251a of the first shielding part 251 are hinged to each other. A second lead-out hole (not shown) is provided in the front and rear frames 20b of the casing 20 through which the second support pieces 252a pass to elevate and descend from the lower portion of the casing 20 .

When describing this in more detail on behalf of the first shielding part 251 shown in the cross-sectional view of FIG. x, due to the hinge coupling structure of the first support pieces 251a,

The support pieces 251a passing through the first draw-out hole 251b and leaving the casing 20 are discharged (like drooping) downward in the lower space in the lower space of the access floor F by their own weight,

Conversely, in the lower space of the access floor (F), the other side support piece (251b) on the other side that rises in the upper vertical direction and enters the hollow part (21) of the casing (20) through the first draw-out hole (251b) is the casing ( Due to the sliding coupling structure on the hollow part 21 of 20), it becomes a flat plate structure,

By mounting the cover panel 23 , the size of the hole through which the connector 10 is exposed is minimized, and horizontal movement of the connector 10 is possible in the forward, backward, left, right, and forward directions.

The shielding operation of the first shielding part 251 composed of the first support pieces 251a is equally applied to the second shielding part 252, except that the first support pieces 251a are the front and rear frames 20b. There is only a difference in that the slide moves along, and the second support pieces 252a slide along the inner end first support piece 251a of the first shielding part 251, not the left and right frames 20a, The specific principle is the same.

In the above description of the present invention, with reference to the accompanying drawings, a connector fixing device for an air line mask having a specific shape and structure has been mainly described, but the present invention is capable of various modifications, changes and substitutions by those skilled in the art, such modifications, Changes and substitutions should be construed as falling within the protection scope of the present invention.
