[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gas plug attachment structure in which a gas plug is connected to a terminal portion of a flexible gas pipe and is fixed to a wall or a drain board of a sink.

[0002]

[Description of Prior Art]

 Conventionally, gas stoppers have been fixed to rigid gas pipes that have a supporting force by utilizing the supporting force of the pipes themselves, so it was not necessary to fix them to walls or drain boards. However, at present, such rigid pipes are rarely used, and instead, flexible gas pipes (hereinafter abbreviated as flexible pipes) that use bellows that do not have a supporting force are often used.

As a gas plug mounting structure in which a gas plug is connected to the end portion of this flexible tube and fixed to a drain plate or wall surface of a sink, the one described in Japanese Utility Model Publication No. 2-40356 is known. It As shown in Fig. 7, a flange (21) is provided on a tubular casing (2) for mounting a gas plug, and a plurality of tightening bolts (3) (3) are passed through the flange (21). By the way, a locking piece (4) is eccentrically screwed to the tip of each tightening bolt (3).

When fixing the casing (2) to the substrate (7) such as a draining plate, as shown by the image line in FIG. 8, the locking piece (4) is rotated to project inward. In addition to eccentricity, the tip of the tightening bolts (3) (3) is inclined inward as shown in Fig. 9 to form a through hole (8) of a predetermined size formed in the substrate (7). Insert the casing (2). Since the locking piece (4) is screwed onto the tip of the tightening bolt (3), which is longer than the casing (2), it is shown in the same figure by tilting the tip so that it points inward. In this way, the locking pieces (4) (4) are arranged in a circle smaller than the inner diameter of the through hole (8), and the casing (2) together with the locking pieces (4) (4) is 8) Can be inserted into.

After the insertion, the head of the tightening bolt (3) is rotated 180 °, the locking piece (4) is projected outward as shown by the solid line in FIG. 8, and the tightening bolt (3) is removed. Tighten and press the locking piece (4) to the back side of the flange (21). When the substrate (7) is pressed by the locking piece (4) and the flange portion (21), the casing (2) is fixed, and then the flexible tube (9) is fixed as shown in FIG. When the gas stopper (60) connected to is fixed to the casing (2), the gas stopper (60) is fixed to the substrate (7).

However, with this gas plug mounting structure, it takes time to tighten the tightening bolt (3), and the protruding state of the locking piece (4) changes when it is inserted into or fixed in the through hole (8). It's difficult to get it done. This is because the tightening bolt (3) is longer than the casing (2), and the moving distance of the locking piece (4) screwed to the tip of the tightening bolt (3) is longer, so that the locking piece (4) moves to the base plate (4). This is because the amount of tightening until it comes into pressure contact with the back side of 7) increases, and the locking piece (4) cannot be operated directly, and it is reversed without being able to grasp its protruding posture.

[0007]

[Technical issues]

 In view of this point, the present invention provides "a casing (2) for fixing a gas stopper (60) with a flange portion (21) and a plurality of tightening bolts (3) (3) on the flange portion (21). Through each other, screw the locking piece (4) into the tip of each tightening bolt (3), and attach the peripheral edge of the through hole (8) drilled in the board (7) to be mounted to the flange part. (21) and the locking piece (4), the gas stopper mounting structure is designed to be clamped and fixed. ”In this case, the distance from the flange (21) to the initial position of the locking piece (4) is shortened. The task is to make the stopper (4) directly operable to facilitate the installation of the gas tap.

[0008]

[Technical means]

 The technical means of the present invention for solving the above-mentioned problem is that "the tightening bolts (3) (3) are passed through the flange part (21) in a swingable manner, and the side wall of the casing (2) is , A notch (24) that is large enough to insert the locking piece (4) is formed in the inner space of the locking piece (4) (4), and each locking piece (4) is notched. When inserted in the portion (24), these locking pieces (4) (4) are positioned within a circle smaller than the diameter of the through hole (8). ”

[0009]

[Action]

 The above technical means act as follows. With the position of each locking piece (4) aligned with the position of the notch (24), tilt the tips of the tightening bolts (3) (3) inward, and ) Are housed in the casing (2) through the corresponding notches (24), the locking pieces (4) (4) are located in a circle smaller than the diameter of the through hole (8). The casing (2) equipped with the locking piece (4) is inserted into the through hole (8) without any trouble.

When the insertion is completed, a finger is put in the casing (2) and the locking piece (4) is pushed out, and the tightening bolt (3) is swung to project from the casing (2). Then, while holding the locking piece (4) in a protruding state, tighten the tightening bolt (3) to bring the locking piece (4) into pressure contact with the rear surface of the flange part (21), and 21) and the locking piece (4) pinch the board (7) to be attached, and the casing (2) is fixed to the board (7).

As described above, the notch (24) is provided on the side wall of the casing (2), and the position of the locking piece (4) when inserted into the through hole (8) is aligned with this position. Therefore, the tightening amount until the locking piece (4) is pressed against the back surface of the flange portion (21) is reduced. In addition, a finger can be inserted into the casing (2) and the locking piece (4) can be directly operated to project from the casing.

[0012]

【effect】

 Since the amount of operation of the tightening bolt (3) until the locking piece (4) contacts the board (7) is reduced, the tightening time of the locking piece (4) is reduced. The locking piece (4) can be easily pushed out of the casing (2) with a finger. By these, the casing (2) can be more easily fixed to the board (7) to which the casing (2) is attached.

[0013]

【Example】

 Next, the embodiment of the present invention described above will be described in detail with reference to the drawings. In the first embodiment, as shown in FIGS. 1 and 2, the casing (2) containing the gas stopper (60) having the plug (65) is attached to the sink board (7). Yes, the flexible tube (9) is connected in advance to the flexible tube connecting fitting (67) protruding from the casing (2).

After fixing the casing (2), the gas plug (60) is connected to a socket (not shown) provided in the gas pipe on the downstream side to the plug (65), the gas circuit is opened, and the socket is opened. It is known that the gas stopper (60) is closed together with the removal. In this case, the gas plug (60) is housed and fixed inside the rectangular casing (2) having an open upper part, and the plug (65) is projected toward the open end of the casing (2). Further, the flexible tube connection fitting (67) is projected from the bottom of the casing (2) to the back side.

Further, the casing (2) is provided with a flange portion (21) at an upper edge portion thereof, and a plurality of tightening bolts (3) and (3) are provided while penetrating the flange portion (21). A locking piece (4) is screwed near the tip of each tightening bolt (3). On the side surface of the casing (2), a notch (24) which is a storage port of the locking piece (4) is formed at a position corresponding to the insertion portion of the tightening bolts (3) and (3).

When the tightening bolts (3) (3) are inclined, as shown in FIGS. 4 and 5, in order to allow the tips of the tightening bolts (3) (3) to escape into the casing (2), A relief groove (25) is provided continuously from the center of the cutout portion (24) and has an inverted T shape together with the cutout portion (24). In addition, the locking piece (4) is a rectangular plate-shaped body as a whole, and a tightening bolt (3) is screwed in the vicinity of the center of the locking piece (4). (44) is provided.

The procedure for attaching the casing (2) having the above-mentioned respective parts will be described below with reference to FIGS. 2 to 6. First, the flexible tube (9) is pulled out from the inside of the substrate (7) and is connected to the flexible tube connecting fitting (67) outside the through hole (8). Then, as shown by the chain double-dashed line in FIG. 4, the locking pieces (4) and (4) are pulled inward so that they are located in a circle smaller than the diameter of the through hole (8), and the locking pieces (4 ) (4) from the cutout (24) into the casing (2) and the tightening bolts (3) and (3) from the relief groove (25) while connecting the casing (2) to the flexible tube. Tilt the side wall on the side where the metal fitting (67) protrudes downward so that the flexible tube connecting metal fitting (67) is inserted into the through hole (8) first, and then gradually through the side wall. (8) Insert into the inside.

As the insertion progresses, the casing (2) is sequentially returned from the tilted posture, and is held in the horizontal posture when it comes into contact with the peripheral surface of the through hole (8). Then, when the casing (2) is inserted into the through hole (8) and the locking pieces (4) and (4) reach the back side of the substrate (7), as shown by the solid line in FIG. (4) Push out the locking pieces (4) (4) housed in the inner part of () to project them outward.

When each tightening bolt (3) is tightened while maintaining this state, the locking piece (4) is formed so that its convex portion (44) is continuous with the notch portion (24) and is directed upward. Ascending while sliding on the escape groove (25), its upper surface eventually comes into contact with the peripheral edge of the through hole (8). At this time, since the long side portion following the convex portion (44) is in contact with the side wall of the casing (2), the tightening bolt (3) does not rotate together with the locking piece (4).

When the tightening bolt (3) is further tightened, the base plate (7) is pinched by the locking piece (4) and the flange portion (21), and the casing (2) can be fixed to the substrate (7). .. Since the initial position of the locking piece (4) is set inside the notch (24) on the side surface of the casing (2) and is close to the flange (21), the operation amount of the tightening bolt (3) is The substrate (7) can be clamped by the locking piece (4) and the flange (21) in a short time.

Incidentally, even if the convex portion (44) is not provided on one long side of the locking piece (4), the function of preventing the locking piece (4) from rotating is not hindered. Since the locking pieces (4) (4) do not interfere with the flexible tube connecting fitting (67), the gas stopper (60) to which the flexible tube (9) is connected is stored in the casing (2) while the substrate ( It is attached to 7). In this embodiment, the notches (24) (24) are formed on the side walls parallel to the axial direction of the flexible tube connection fitting (67), but the notches (24 ) Similar effects can be obtained by forming (24).

Next, a second embodiment shown in FIG. 5 is of a type in which a cylindrical casing (2) containing a gas stopper (60) is inserted into a through hole (8), and a flexible tube The connecting fitting (67) and the gas stopper (60) are coaxially continuous with each other, and the flexible pipe connecting fitting (67) is projected downward from the bottom of the casing (2). ) Is fixed, and the flexible tube (9) is connected to the flexible tube connection fitting (67).

The plurality of notches (24) (24) formed on the side surface of the casing (2) have a horizontally long length capable of accommodating the locking piece (4) by inclining the tightening bolts (3) (3). In addition to being a hole, a relief groove (25) is also provided continuously in the upper center. In this embodiment, the locking piece (4) has a crescent shape consisting of two arcs, and one arc (41) is made to coincide with that of the outer diameter of the body of the casing (2), and this arc ( 4 Tightening bolts (3) are screwed near 1).

Also in this case, as in the first embodiment, first, the tip of the tightening bolt (3) is inclined inward to house the locking piece (4) in the casing (2), and then the casing (2) is removed. After inserting it into the through hole (8), return the tip of the tightening bolt (3) to the outside to form an overhanging part facing the flange part (21), and this and the flange part (21). Clamp the substrate (7).

Since the circular arc (41) substantially coincides with that of the body portion of the cylindrical casing (2), the circular arc (41) is fixed when the tightening bolt (3) is tightened. By contacting the outer circumference of 2) and pressing it, it functions as a detent for the locking piece (4). Regarding the position to cut the notch (24), there is no interference between the built-in gas plug (60) or the flexible tube connecting fitting (67) and the locking piece (4), and the locking piece (4 In order to shorten the moving distance of 4), consider the storage space of the locking piece (4) inside the casing (2) and the effective screwing length of the locking piece (4) of the tightening bolt (3). It is good to set.

As shown in FIG. 7, the through hole of the tightening bolt (3) formed in the flange portion (21) is made into a long hole (21a) having a long axis in the moving direction of the locking piece (4). The tightening bolts (3) may be located inside when inserting and outside when tightening. The material of the locking piece (4) may be synthetic resin if it is not frequently attached and removed.In that case, insert a metal insert into the female thread or bury the nut. It is better to have a structure with improved durability.
