Description

Plug for Hose Coupling Device {Plug for Hose Coupling Device}

The present invention relates to a hose coupling mechanism, and more particularly, to a plug of the hose coupling mechanism that is economical because it is easy to configure the piping by a quick detachment corresponding to the situation of the field and no leakage occurs.

Typically, a fluid transfer device composed of a pump, a hose, a valve, and the like is a means for supplying water or a chemical liquid at a required flow rate and flow rate, and is widely used for various purposes such as industrial, agricultural, fire suppression, and vehicle. At this time, it is necessary to remove or extend the piping hose depending on the purpose and place of supplying the water (chemical or industrial) or the like, and for this purpose, a hose coupling mechanism that is a pipe joint member is required.

1 is a block diagram showing a conventional hose coupling mechanism.

Referring to FIG. 1, a socket 10 and a plug 15 are used to engage a male and female structure in a pipe using a hose so that a flow path is communicated and airtight is maintained. One end of the socket 10 is connected with a toothed connector 50 having a hermetic packing 51 and a nut 55, and the other end is connected with a plug 15 having a locking groove 52. In addition, a pipe hose 53 is connected to one side of the connection port 50, and a bending portion 54 which is banded with a rubber material or the like is formed at the connection portion.

By the way, in the case of the hermetic packing 51 formed in the connection port 50, if it is not replaced frequently, the sealing force is weakened by strong water pressure or the like, and various problems such as water leakage occur. Therefore, the connector 50 should be replaced from the socket 10 and the pipe hose 53 to replace the connector 50 from time to time, but on one side of the connector 50, the pipe hose 53 is banded, so it must be released to remove the connector ( 50) can be replaced, but there is a problem that the disassembly of the bending portion 54 is not so easy. In addition, since the process of the bending part 54 is not easy in actual field, after cutting off one side of the piping hose 53, connecting the piping hose 53 to the new connection port 50 and coupling with the socket 10 There is often. As a result, in addition to the complexity of the bending work, the problem of waste of parts and materials is occurring.

On the other hand, when the pipe connection of the hose is slightly complicated and connected to three or more ports, a ready-made product (for example, a T-shaped pipe for water pipe piping) that is suitably used for other purposes is introduced. In many cases, a spiral that is poorly connected to the connector 50 is formed, and the detachability with the socket 10 is extremely poor. That is, when the pipe hose is connected in three directions using a T-shaped connector that has been used in the related art, there is a closed end that causes a problem such as leakage due to poor connection.

As such, the T-shaped connector, which has been used in the past, must be wound up again after connecting the hose to the T-shaped connector to prevent water and chemical leakage from bad joints. Not only is this cumbersome, but the connection structure with the socket is not so close that the confidentiality is not maintained for a long time. And when hose hoses are connected to several to several dozen plastic houses using one motor and compressor, the number of hose pipes is considerable. In this case, the problem of poor connection of distribution pipes causes not only a lot of waste but also work. Even after this is completed, the dismantling work of the tightening banding that is wound on the distribution pipe also has a disadvantage that has emerged as a daunting task.

The present invention devised to solve the above-mentioned shortcomings and shortcomings, and provides a plug of the hose coupling mechanism that is easy to construct the piping by a quick detachment corresponding to the on-site situation, and no leakage occurs, thereby ensuring economic efficiency. For that purpose.

A body having at least one inlet and at least two outlets in communication; And a connecting pipe 25 coupled to the airtight body using a configuration such as a spiral on the body, and detachable from the socket 10 at an outer end thereof.

According to the present invention, the body 20, 21, 22 is applied to the configuration disposed in the connection pipe 25 of the same diameter.

As a modification of the present invention, the body 30 is also applied to the configuration in which the expansion pipe 35, 36, 38, which is larger in diameter on the inlet side is mixed with the connection pipe 25.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

2 to 5 is a block diagram showing various embodiments of the hose coupling mechanism according to the present invention, Figure 6 is a block diagram showing a plug according to a modification of the present invention.

The present invention relates to a coupling mechanism for quickly detaching a joint of a hose pipe using a socket 10. Hose pipes, unlike metal pipes, are not fixed and are used for the purpose of flexibility and mobility. The hose pipes are mainly made of synthetic resin. In general, any type of piping requires a fitting for connecting the joints, and the coupling mechanism is particularly useful for hose piping in which detachment is quickly performed.

According to the present invention, a body provided to communicate at least one inlet and two or more outlets is used. As shown in Figs. 2 to 4, three or more spheres are provided by combining the inlet and outlet as the body, and in the case of the three spheres, the T-shape of FIG.

In addition, according to the present invention, the connection pipe 25 detachably attached to the socket 10 at the outer end is coupled to maintain airtightness using a spiral on the body. The connecting pipe 25 is provided with the spiral 25c in an inner end, and becomes a straight pipe form in an outer end. In the vicinity of the spiral 25c, the engaging groove 25b is formed together with the annular jaw 25a. Accordingly, when the socket 10 and the connection pipe 25 are attached or detached, the ball of the socket 10 is accommodated in or detached from the locking groove 25b of the connection pipe 25.

At this time, the body 20, 21, 22 as an example of the subject innovation is applied to the configuration disposed in the connecting pipe 25 of the same diameter. 2 shows that a plurality of connecting pipes 25 having the same diameter are connected to the bodies 20, 21, 22. Which one of the connecting pipes 25 is the inlet and the rest is the outlet can be selected in various ways.

And while the body 20, 21, 22 of the present invention is mainly formed of a brass material, the connection pipe 25 is very preferably formed of a stainless steel pipe in consideration of wear resistance. It is preferable to use an adhesive together in connection with the connection pipe 25 rather than using only the spiral 25c. Of course, instead of the adhesive, it is also possible to use teflon tape or the like which is a conventional airtight means.

In addition, in the present invention, the coupling of the body 20, 21, 22 and the connection pipe 25 is described mainly in the form of a spiral coupling method, but in addition to this method can be applied as a keyway type or an integral type, as shown in FIG. This will be explained through 5.

That is, the guide groove 40 is formed in the inner end of the body 20, 21, 22 in Figure 5a, and the connection pipe (in the state in which the projection 41 is formed at one end of the connection pipe 25) The protrusion 41 of the 25 may be inserted into and detached from the guide groove 40 of the bodies 20, 21 and 22 (key groove method), and the bodies 20 and 21 may be removed as in the case of FIG. 5B. ) 22 and the connector 25 may be integrally formed, but may be configured as the same material, but the materials of the body 20, 21, 22 and the connector 25 may be configured differently. It may be.

In addition, as shown in FIG. 5C, the end portions of the bodies 20, 21, and 22 are formed to protrude outward to form the dosing ring 42, and then the connecting pipe 25 is coupled to each other at the outside or the inside of the dosing ring 42. Alternatively, as shown in FIG. 5D, the stepped portions 43b of the auxiliary ring 43 in which the hermetic packing 43a is pressed on the inner side of the bodies 20, 21, 22 may be the body 20, 21, 22. After tightly fixing the inner groove 44 of the), the connection pipe 25 may be coupled to the auxiliary ring 43 by fitting.

On the other hand, according to a modification of the present invention as shown in Figure 6 is a configuration in which the expansion pipe 35, 36, 38, the tube diameter is increased in the inlet side is mixed with the connecting pipe 25 This is possible. In the three-spherical (T-shaped) body 30 as shown in FIG. 6A, the expansion tube 35 is coupled to one side, but in one or two places in the four-spherical body 30 as shown in FIGS. 6B and 6C. Optionally join the dilator 36, 38. The configuration of the expansion tubes 35, 36, 38 and the manner of coupling to the body 30 is the same as the case of FIGS.

As such, expansion pipes 35, 36, 38 having a larger diameter than the connection pipe 25 are used at the inlet side of the body 30. Based on the body 30, the inlet is the portion where the fluid enters, and the outlet means the portion where the fluid exits. Increasing the diameter of the inlet side than the outlet side is advantageous in reducing the pipe resistance in the body 30. The size of the expansion pipes 35, 36, 38 is determined to be proportional to the ratio of the inlet flow path cross-sectional area and the outlet flow path cross-sectional area.

7 is a schematic view showing a state of use of the plug according to the present invention.

7 shows a pipe for supplying water or a chemical liquid to a plastic house (not shown) arranged in a plurality of rows, a reference numeral 12 is a tank, a reference numeral 16 is a pump including a motor, and after the pump 16, the present invention Various plugs are used in suitable combinations. Although only the hose and the body 21 and 22 are shown in the figure, the socket 10 is interposed in the interconnected portion.

In use, if the capacity of the pump 16 is sufficiently large, the length of the pipe is short, or the number of branches of the pipe is small, there is no problem even if the same connecting pipe 25 is used as shown in FIG. If the capacity of the pump 16 is insufficient or obsolete, it is necessary to replace it immediately with a plug of the type shown in FIG. 6 to smoothly supply water or chemical liquid. In this case, if the plug of the present invention is used, the piping can be changed quickly and there is no fear of leakage. Of course, when replacing with a plug as shown in Figure 6 socket 10 also uses a corresponding inner diameter standard.

On the other hand, in the embodiment of the present invention, but shown and described the plug of the three spheres and four spheres, the same concept can be applied to more than five spheres. And the expansion pipe 35, 36, 38 on the inlet side is arranged in a smaller amount than the connecting pipe 25 on the outlet side.

In addition, the socket 10 is detachable from the plug 10 is a structure that accommodates the ball, but it is also easily applicable to take other structures.

In addition, the example used for the pipe of the agricultural vinyl house, but can be used in the same way for industrial, fire suppression, vehicle. However, when the viscosity of the target fluid becomes large, it is preferable to arrange the plug of FIG. 6 more than FIG. 2.

According to the above configuration and operation, the present invention has an effect of ensuring economic efficiency because the piping configuration is easy and quick leakage in response to the situation of the site does not occur leakage phenomenon.

The present invention is not limited to the embodiments described, and it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention, and therefore such modifications or Modifications will be said to belong to the utility model registration claims of the present invention.
