Description

One-touch type water and sewage pipe connector

[0001] The present invention relates to a one-touch type water and sewage pipe connection, and more particularly, to a one-touch type water and sewage pipe connection that facilitates pipe connection without tools when connecting pipes buried in the ground or in an external environment.

[0002] The information contained in this background section is intended to enhance understanding of the background of the invention and may include matters that are not prior art already known to a person of ordinary skill in the art to which this technology pertains.

[0003] In general, for living infrastructure such as houses and roads, underground pipes are installed to supply drinking water and sewer pipes to treat wastewater, and the necessary contents are supplied or unnecessary contents are discharged.

[0004] Up to now, the types of pipes used to build water supply and sewage facilities in our country have mainly been steel pipes for water supply, and reinforced concrete pipes (Hume pipes) for sewage.

[0005] However, as the service life of the already constructed facility base increases, problems such as water contamination due to corrosion in the case of steel pipes, contamination due to rust inhibitors coated on the inner diameter, and water leakage are pointed out as problems, and reinforced concrete pipes have the disadvantage of being corroded by hydrogen sulfide contained in sewage and affected by acids, alkalis, wastewater, salt, and organic matter.

[0006] Polyethylene pipes for water and sewage (hereinafter referred to as PE pipes) have excellent properties as pipes as they are free from corrosion, rust, and limescale.

[0007] Furthermore, water and sewage PE pipes are non-toxic and odorless, have excellent physical and chemical properties such as acid and alkali resistance, and have a long service life of more than 50 years, so they are used as plumbing pipes and buried pipes in many fields today.

[0008] In addition, due to the nature of the water supply and sewage PE pipe, when it is cut to a length of about 6 m and buried underground, a connecting port (connecting socket) is used at the connecting part of the water supply and sewage PE pipe to prevent the fluid or gas transported inside the water supply and sewage PE pipe from leaking through the gap in the connecting part.

[0009] PE pipes for water and sewage systems have the advantage of being lightweight, easy to handle, and available in a variety of sizes for various uses. However, they have the disadvantage of not being widely used due to defects such as deformation of the molded shape after being buried underground or partial breakage due to brittleness under pressure.

[0010] Figure 1 is a longitudinal cross-sectional view of a conventional water and sewage pipe connection.

[0011] Referring to Fig. 1, a conventional water supply and sewage pipe connection (10) is configured such that water supply and sewage pipes (1) are inserted into each side of a body (11) to connect the water supply and sewage pipes (1) to each other, a seal (13) and a tightening part (14) are inserted into the inner surface of a cap fastening part (12) of the body (11), and a cap (15) is rotated and fastened to the outer surface of the cap fastening part (12).

[0012] Since the cap (15) is configured to be fastened to the outer surface of the cap fastening portion (12) with a screw-type fastening structure, the gap between the connection port (10) and the water supply and sewage pipe (1) is blocked by tightening or loosening the cap (15) while rotating it clockwise or counterclockwise to press the fastening portion (14), thereby preventing the fluid flowing inside the water supply and sewage pipe (1) from leaking.

[0013] However, conventional water and sewer pipe connectors have the problem that connecting and disconnecting water and sewer pipes is difficult and time-consuming. Furthermore, water and sewer PE pipes can be subject to external shocks or pressure changes in the fluid transported within, causing them to vibrate and fail to securely seal with the connector (connection socket), leading to leakage of the fluid transported within the water and sewer pipes through the joints.

[0014] The purpose of the present invention is to provide a one-touch type water and sewage pipe connection fitting that facilitates pipe connection without tools in a one-touch type (push fit connection method) when connecting pipes in the ground or in an external environment.

[0015] The purpose of the present invention is to provide a one-touch type water and sewage pipe connection, which can be firmly installed without water and sewage pipes being arbitrarily separated (detached) by a hook cap and a collet when the main cap is arbitrarily detached due to an external impact after pipe construction.

[0016] The purpose of the present invention is to provide a one-touch type water and sewage pipe connection that allows easy connection and disconnection of water and sewage pipes simply by rotating them 90°.

[0017] According to one embodiment of the present invention, a one-touch type water and sewage pipe connector is a water and sewage pipe connector for connecting two water and sewage pipes to each other and preventing leakage of fluid flowing inside the water and sewage pipes, comprising: a connector body having a fastening portion formed with an opening for inserting a water and sewage pipe on one side and the other side, and a hook cap coupling groove formed on an inner circumference of the fastening portion; a hook cap inserted into the opening, and having a plurality of elastic hooks formed so as to be elastically inserted into the hook cap coupling groove and coupled to the fastening portion, one side of the elastic hook being formed to have a round shape, such that when the elastic hook is rotated to one side by a user while being inserted into the hook cap coupling groove, the elastic hook is inserted and released from the hook cap coupling groove; an annular collet coupled into the hook cap, and having a plurality of clip portions formed so as to be elastically pressed against an outer circumference of the water and sewage pipe to fix the water and sewage pipe, and having a locking protrusion formed on the lower end of the clip portion; And it is positioned to surround the connecting part, a pipe penetration hole is formed in the center through which a water and sewage pipe passes, and the inner circumference includes a main cap that can be connected and separated from the connecting body.

[0018] Here, a support protrusion is protruded on the outer surface of the fastening portion to support the end of the main cap.

[0019] In addition, one side of the hook cap is knurled, and when the knurled portion rotates, the portion having a round shape of the elastic hook is inserted and released from the hook cap joining groove.

[0020] Additionally, the elastic hook of the hook cap is formed to be inclined inward.

[0021] In addition, four hook cap connecting grooves and elastic hooks are formed at 90° intervals, and when each elastic hook is rotated to one side while being inserted into each hook cap connecting groove, each elastic hook is simultaneously inserted and released from the hook cap connecting groove.

[0022] Additionally, when the end of the water supply and sewer pipe is inserted into the collet, the clip portion is elastically pressed against the outer surface of the water supply and sewer pipe to fix the position of the water supply and sewer pipe.

[0023] Additionally, a circular groove is formed around the pipe penetration hole at the top of the main cap, and a foreign matter prevention ring is inserted into the circular groove.

[0024] According to the present invention, when burying a pipe in the ground or connecting a pipe in an external environment, the pipe can be easily connected without tools using a one-touch type (push fit connection method).

[0025] According to the present invention, when the main cap is arbitrarily detached due to external impact after pipe construction, the water supply and sewage pipe can be installed firmly without being arbitrarily separated (detached) by the hook cap and collet.

[0026] According to the present invention, the water supply and sewage pipe can be easily removed simply by rotating it 90°.

[0042] A one-touch type water supply and sewer pipe connection (100) according to one embodiment of the present invention is a pipe connection device for connecting two water supply and sewer pipes (1) to each other and preventing leakage of fluid flowing inside the water supply and sewer pipes (1). The present invention is not limited to water supply and sewer pipes (1), and can be equally applied to pipes used in buildings.

[0043] Hereinafter, the components of a one-touch type water and sewage pipe connection (100) according to one embodiment of the present invention will be described in detail.

[0044] A one-touch type water and sewage pipe connection (100) includes a connection body (110), a hook cap (120), a collet (130), and a main cap (140).

[0045] The connecting body (110) is formed with a fastening portion (111) having an opening (0) on one side and the other side into which a water supply and sewage pipe (1) is inserted. That is, the connecting body (110) has a structure in which both sides are open. A hook cap coupling groove (113) is formed on the inner surface (inner wall) of the fastening portion (111), and a support protrusion (119) for supporting the end of the main cap (140) protrudes on the outer surface of the fastening portion (111). When the main cap (140) is connected (assembled) to the fastening portion (111), the support protrusion (119) prevents the main cap (140) from sagging downward.

[0046] The hook cap (120) is annular and is inserted into the opening (O). The hook cap (120) is formed with a plurality of elastic hooks (121) so that it can be elastically inserted into the hook cap joining groove (113) and joined with the fastening portion (111). The elastic hooks (121) of the hook cap (120) are formed to be inclined inward.

[0047] The hook cap (120) has one side knurled, and when the knurled portion (122) rotates by the user's action, the round-shaped portion of the elastic hook (121) is inserted and released from the hook cap joining groove (113).

[0048] The collet (clip, 130) is annular and is coupled within the hook cap (120). The collet (130) is elastically pressed against the outer surface of the water supply and sewage pipe (1) to form a plurality of clip portions (131) for fixing the water supply and sewage pipe (1).

[0049] When inserting the end of the water supply and sewage pipe (1) into the collet (130) to connect the water supply and sewage pipe (1) into the water supply and sewage pipe connection port (100), the clip portion (131) is elastically pressed against the outer surface of the water supply and sewage pipe (1) to fix the position of the water supply and sewage pipe (1), and the clip portion (131) is elastically pressed against the outer surface of the water supply and sewage pipe (1) to fix the position of the water supply and sewage pipe (1).

[0050] In this way, when the collet (130) stably fixes the water supply and sewage pipe (1), the collet (130) is maintained in a state of being slightly moved upwards of the hook cap (120).

[0051] An O-ring (240) is inserted between the hook cap (120) and the fastening part (111) to prevent leakage from the water supply and sewage pipe (1).

[0052] An insert ring (230) is inserted between the O-ring (240) and the hook cap (120) to prevent the O-ring (240) from being detached from the fastening portion (111) and from being deformed.

[0053] The main cap (140) is positioned to surround the fastening portion (111). The main cap (140) has a pipe penetration hole (141) formed in the center through which a water supply and sewage pipe (1) passes, and the inner circumference thereof can be connected to and separated from the connecting body (110).

[0054] A circular groove is formed around the pipe penetration hole (141) at the top of the main cap (140), and a foreign matter prevention ring (144) is inserted into the circular groove. The foreign matter prevention ring (144) is in close contact with the outer surface of the water supply and sewage pipe (1) to remove contaminants adhering to the outer surface, thereby preventing contaminants from entering the water supply and sewage pipe connection port (100), thereby enabling quick installation even in an environment exposed to contaminants, and effectively preventing clogging of the water supply and sewage pipe (1) by contaminants.

[0055] In this way, the characteristics of the one-touch type water and sewage pipe connection (100) according to one embodiment of the present invention are described as follows.

[0056] A one-touch type water and sewage pipe connection (100) according to one embodiment of the present invention is a connection for a pipe buried in the ground or used in an external environment, and unlike the conventional screw method that takes a lot of time, it uses a push-fit connection method (one-touch structure) to shorten the work time.

[0057] In addition, the one-touch type water and sewage pipe connection (100) according to one embodiment of the present invention has a structure in which the main cap (140) first fixes the water and sewage pipe (1), and the hook cap (120) and the collet (130) fix the water and sewage pipe (1) again. In the event that the main cap (140) is arbitrarily detached due to an external impact after the water and sewage pipe (1) is constructed, the hook cap (120) and the collet (130) may be configured as a double locking structure to prevent the water and sewage pipe (1) from falling off (separating).

[0058] In addition, in the one-touch type water and sewage pipe connection (100) according to one embodiment of the present invention, it is easy to connect the main cap (140) to the water and sewage pipe (1) in a one-touch manner as shown in FIG. 10.

[0059] That is, when the water supply and sewage pipe (1) is connected (fastened) within the pipe connection port (100), as shown in FIG. 9, when the water supply and sewage pipe (1) is inserted into the pipe penetration hole (141), when the end (1a) of the water supply and sewage pipe (1) is inserted into the collet (130), the clip portion (131) is elastically pressed against the outer surface of the water supply and sewage pipe (1) to fix the position of the water supply and sewage pipe (1).

[0060] In addition, in the one-touch type water and sewage pipe connection (100) according to one embodiment of the present invention, when the water and sewage pipe (1) is separated (detached) from the connection (100), the main cap (140) is rotated 90° counterclockwise as shown in FIG. 10, and then the main cap (140) is lifted upward and separated as shown in FIG. 11. Then, when the collet (130) is pressed with a finger, the clip portion (131) is pushed rearward by the clearance (D) and separated from the outer surface of the water and sewage pipe (1), so that the water and sewage pipe (1) can be easily separated from the water and sewage pipe connection (100).

[0061] In addition, in the one-touch type water and sewage pipe connection (100) according to one embodiment of the present invention, a hook cap coupling groove (113) is provided to prevent the hook cap (120) from coming off.

[0062] In addition, in the one-touch type water and sewage pipe connection (100) according to one embodiment of the present invention, a contaminant removal ring (soft plastic or rubber) (143) is pressed against the outer surface of the water and sewage pipe (1) to remove contaminants adhering to the outer surface thereof. In this way, since contaminants do not flow into the water and sewage pipe connection (100), not only can quick installation be achieved even in an environment exposed to contaminants, but also clogging of the water and sewage pipe (1) by contaminants can be prevented. In addition, the internal components of the connection (100) can be protected, and the rework rate can be reduced due to minimizing exposure to contaminants when connecting water and sewage pipes.

[0063] While the embodiments of the present invention described above have been described with reference to the drawings to aid understanding, these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent embodiments are possible. Therefore, the true scope of technical protection of the present invention should be defined by the appended claims.
