[0001] The present invention relates to a hose fitting fastening member and a connecting method using the same, and provides a fitting fastening member and method thereof that enable immediate connection on site when a hose is damaged.

[0002] Fittings are used in systems to connect straight sections of hoses or pipes to facilitate fluid flow. They are designed with fluid flow in mind, taking into account various factors such as material, pressure, and temperature.

[0003] However, if a hose breaks in the field, the entire hose must be replaced. This significantly increases the replacement cost. Furthermore, the hose and the fasteners connected to it must also be replaced, further increasing the cost.

[0004] Additionally, in addition to the replacement cost, you will also incur losses due to equipment downtime as you will need to visit the dealer to replace the hose assembly.

[0005] Therefore, in the present invention, there is a need to develop a simple device that can be easily connected when a hose is broken.

[0006] In order to solve the above problem, the purpose of the present invention is to provide a hose fitting fastener and a connection method using the same, which can be easily connected on site through partial replacement instead of the hassle of replacing the entire hose when the hydraulic hose is damaged.

[0008] The first coupling member has a left-hand thread formed on one inner surface to receive the first hose inwardly and a right-hand thread formed on the other inner surface, the second coupling member has a right-hand thread formed on one inner surface to receive the second hose inwardly and a left-hand thread formed on the other inner surface, and the coupling nipple has a right-hand thread formed on one outer surface to be coupled with the right-hand thread of the other side of the first coupling member and a left-hand thread formed on the other outer surface to be coupled with the left-hand thread of the other side of the second coupling member.

[0009] The first and second connecting members are characterized in that a step is formed inside them to guide the depth for accommodating the first and second hoses.

[0010] In order to solve the above problems, the present invention provides a hose connection method using a hose fitting fastener, characterized in that it includes a hose cutting step of cutting the hose to both sides based on a damaged portion of the hose and removing the damaged portion to separate the hose into a first hose and a second hose; a hose connection step of receiving and connecting the first hose into one side of a tubular first coupling member having a left-hand thread formed on one inner surface and a right-hand thread formed on the other inner surface, and receiving and connecting the second hose into one side of a tubular second coupling member having a right-hand thread formed on one inner surface and a left-hand thread formed on the other inner surface; and a coupling nipple connection step of connecting the first hose and the second hose by fastening between the first coupling members and the second coupling members on both sides, using a coupling nipple having a right-hand thread formed on one outer surface and a left-hand thread formed on the other outer surface and having a nut shape formed in the center.

[0011] The following effects can be expected by the above solution.

[0012] First, instead of replacing the entire hose when it breaks, you can simply cut off the broken section and use a hose fitting to connect it.

[0013] Additionally, by rotating the nipple, the first and second coupling members on both sides can be simultaneously engaged to connect the first hose and the second hose.
