Description

{CONNECTION DEVICE TO PREVENT LEAKAGE OF FLUID}

The present invention relates to a connecting device that prevents leakage of fluid. More specifically, it relates to a connecting device that prevents leakage of fluid by preventing a packing provided on the inside from coming off, and at the same time, to a connecting device that prevents leakage by blocking a gap between a connecting part where a connecting device and an object introduced into the connecting device are connected, and at the same time, to a connecting device that prevents leakage of fluid by being easy to connect or disconnect with one touch.

Generally, when installing water pipes or hot water pipes for heating, connecting devices are used to connect water supplies such as pipes, hoses, and faucets that are spaced apart from each other. In this case, if the connecting part where the water supplies and connecting devices are connected is not sealed, water leakage may occur, which may hinder the movement of fluids and cause safety accidents due to water leakage.

Meanwhile, Teflon tape or packing is used as a method to prevent leakage and maintain watertightness, but there is a problem that the Teflon tape or packing is damaged by pressure during the bonding process, or the sealing force is reduced due to hydraulic pressure or aging over time, causing it to move from its original position, and thus the sealing force is reduced, resulting in leakage.

In addition, there is a problem of poor workability because the fasteners such as bolts and nuts must be disassembled and reassembled in order to replace the Teflon tape or packing.

FIG. 1 is a cutaway perspective view of a body part (100) of a connecting device for preventing fluid leakage according to one embodiment of the present invention. Referring to FIG. 1, the connecting device for preventing fluid leakage of the present invention may be provided to include a body part (100) provided with a first packing (130), a first support part (110), and a first step part (120) on the inside to seal a connection portion with an object.

The body part (100) is configured to move fluid into the interior by being provided in a tubular shape with both ends open and the inside perforated, and by being connected to objects introduced into the interior. Specifically, the body part (100) is positioned between objects spaced apart from each other, and by connecting objects introduced into both ends, it plays a role in securing a path for smooth fluid movement.

Meanwhile, the target object may be various plumbing materials including faucets, pipes, hoses, and filter housings having a predetermined shape, but is not limited thereto.

The first packing (130) is provided inside the body (100) to seal the connection portion. Specifically, the first packing (130) is positioned to come into contact with an object introduced into the body (100), and serves to maintain watertightness by sealing the connection portion between the body (100) and the object. More specifically, the first packing (130) is provided in a ring shape so as not to impede the flow of fluid, and at the same time, comes into contact with an end portion of the object introduced into the body (100), thereby sealing the connection portion, thereby maintaining watertightness. At this time, the first packing (130) is preferably provided with an elastic material such as rubber or silicone, but is not limited thereto, and it is sufficient if it can seal the connection portion.

The first support member (110) is configured to support the first packing (130) and prevent the first packing (130) from being separated from the original position. Specifically, the first support member (110) is formed to protrude from the inner surface of the body part (100) so that one surface comes into contact with the first packing (130), and prevents the first packing (130) from being separated from the original position due to hydraulic pressure generated from a fluid flowing into the body part (100) or friction generated during a process of joining with an object. At this time, the first support member (110) is preferably provided in a shape corresponding to the first packing (130) and in an annular shape having a larger diameter than the first packing (130). In detail, the first support member (110) is preferably formed in the same shape as the first packing (130) so that the first packing (130) can be completely sealed between the end of the object into which it is introduced and the first support member (110) so as to completely seal the connection portion between the body part (100) and the object, but is formed to be larger than the diameter of the first packing (130), so that the first packing (130) is not separated from the first support member (110).

The first step portion (120) is configured to protrude from one side of the first support portion (110) in the direction in which the first packing (130) is located, thereby preventing the first packing (130) from being separated from the first support portion (110). Specifically, the first step portion (120) is formed integrally with the first support portion (110), and the first step portion (120) is formed to protrude from one side of the first support portion (110) so that the cross section formed by the first step portion (120) and the first support portion (110) can be formed in an “L” shape, thereby preventing the first packing (130) from being separated from the first support portion (110). At this time, it is preferable that the first step (120) not be formed so that it protrudes too low from one side of the first support (110) so that the first packing (130) is easily detached from the first support (110), or so that it protrudes too high so that the first packing (130) does not come into contact with the end of the object.

Hereinafter, a connecting device for preventing fluid leakage will be described in more detail with reference to FIGS. 2 to 5.

The second packing (130') is provided inside the connection port (100') to maintain watertightness. Specifically, the second packing (130') is positioned to come into contact with the object introduced into the connection port (100') and performs the function of maintaining watertightness by sealing the connection portion between the connection port (100') and the object. At this time, the second packing (130') is preferably provided with an elastic material such as rubber or silicone and formed in a ring shape, but is not limited thereto, and it is sufficient if it can seal the connection portion.

The second support member (110') is configured to support the second packing (130') and prevent the second packing (130') from being separated from the original position. Specifically, the second support member (110') is formed to protrude from the inner surface of the connection port so that one side comes into contact with the second packing (130'), and prevents the second packing (130') from being separated from the original position due to hydraulic pressure generated from a fluid flowing into the connection port or a pressure generated during a process of joining with an object. At this time, the second support member (110') is preferably provided in an annular shape with a shape corresponding to the second packing (130') and a diameter larger than that of the second packing (130').

The second step portion (120') is configured to protrude from one side of the second support portion (110') in the direction where the second packing (130') is located, thereby preventing the second packing (130') from being dislodged from its original position.
