[0035] The metal tube 1 has a tube body 11 and a limiting flange 12 that surrounds one end of the tube body 11 and protrudes outward. For example, the metal tube 1 can be bent to change its shape to accommodate space limitations. The limiting flange 12 is formed by stamping the end of the metal tube 1, and the cross-sectional area of ​​the limiting flange 12 is larger than the cross-sectional area of ​​the tube body 11.

[0036] The detachable pipe joint module 2 includes a set 21 , a connecting piece 22 , an anti-diarrhea gasket 23 , and an annular gasket 24 .

[0037] The sleeve 21 is sleeved on the metal tube 1 and has a sleeve body 211, a stopper 212 formed on the inner side of the sleeve body 211 and matched with the limiting flange 12, and a first threaded portion 213 formed on the sleeve body 211, the stopper 212 is pressed against the limiting flange 12 to prevent the sleeve 21 from being separated from the metal tube 1. Specifically, in the first embodiment, the sleeve body 211 includes a bottom wall 211a and a surrounding wall 211b. The bottom wall 211a is annularly sleeved on the tube body 11 and has a front side 211d and a rear side 211e. The bottom wall 211a protrudes from its inner wall surface close to the rear side 211e toward the axis to form the stopper 212, wherein the stopper 212 defines a rear through hole 212b, and the cross-sectional area of ​​the rear through hole 212b is smaller than the cross-sectional area of ​​the limiting flange 12. The abutting portion 212 has an abutting surface 212a facing the limiting flange 12 and for the limiting flange 12 to abut. The limiting flange 12 includes a rear abutting surface 121 and a front abutting surface 122 located on opposite sides, wherein the rear abutting surface 121 is used to abut against the abutting surface 212a. In addition, the bottom wall 211a also has an inner limiting wall surface 211f located on its inner wall surface close to the front side surface 211d and connected to the abutting surface 212a, and the inner limiting wall surface 211f and the abutting surface 212a jointly define a front through hole 212c connected to the rear through hole 212b, and the tube body 11 of the metal tube 1 can extend through the front through hole 212c and the rear through hole 212b, and the limiting flange 12 can extend through the front through hole 212c and abut against the abutting portion 212. On the other hand, the surrounding wall 211b extends from the front side surface 211d of the bottom wall 211a in a direction away from the rear side surface 211e. In this embodiment, the first threaded portion 213 is formed on the inner wall surface of the surrounding wall 211b, and the cross-sections of the sleeve 21 and the connecting member 22 are circular, but not limited thereto. In another embodiment, the cross-sections of the sleeve 21 and the connecting member 22 may also be hexagonal, which is also convenient for applying force.

[0038] The connector 22 has a body 221 connected to the sleeve 21, a joint portion 222 coaxially extending from the body 221 on one side opposite to the sleeve 21, a second threaded portion 223 formed on the body 221 and locked with the first threaded portion 213, and a flow channel portion 224 penetrating the body 221 and the joint portion 222, the flow channel portion 224 being connected to the metal pipe 1 and having the same cross-sectional shape from beginning to end. By virtue of the structure that the cross-sectional shape of the flow channel portion 224 is the same from beginning to end, and the cross-sectional shape of the flow channel portion 224 is also the same as the cross-sectional shape of a water-cooling heat dissipation system, when a fluid (liquid or gas, water is used as an example in this embodiment) flows into the water-cooling heat dissipation system through the flow channel portion 224, the fluid pressure in the flow channel portion 224 and the fluid pressure in the water-cooling heat dissipation system can be consistent, thereby achieving the effect of preventing the water-cooling pipeline in the water-cooling heat dissipation system from being broken due to excessive hydraulic pressure. In addition, a third threaded portion 222 a is formed on the outer wall of the joint portion 222 for locking with the water cooling system.

[0039] In the first embodiment, the main body 221 includes an annular base 221a having a first side 221b opposite to the kit 21 and a second side 221c facing the kit 21, an extension portion 221d extending from the second side 221c, a placement platform 221e formed by the end surface of the extension portion 221d being concave toward the base 221a, and an annular groove 221f formed on the first side 221b and concave toward the second side 221c and surrounding the joint portion 222, the placement platform 221e is formed corresponding to the shape of the anti-diarrhea gasket 23, and the annular groove 221f is formed corresponding to the shape of the annular gasket 24.

[0040] The outer wall surface of the base 221a and the outer wall surface of the surrounding wall 211b are provided with embossed patterns to increase friction, so that the user can better apply force when locking or removing the connecting member 22 and the set 21.

[0041] The anti-diarrhea gasket 23 is flexible, for example, made of rubber material, but the material is not limited to rubber. The anti-diarrhea gasket 23 has a hole 231. The anti-diarrhea gasket 23 is placed on the placement platform 221e and the position of the hole 231 corresponds to the flow channel portion 224, wherein the cross-sectional shape and size of the hole 231 are the same as the cross-sectional shape and size of the flow channel portion 224. In addition, when the anti-diarrhea gasket 23 is placed on the placement platform 221e, one end of the anti-diarrhea gasket 23 will protrude outside the placement platform 221e, and the end located inside the placement platform 221e will be tightly against the wall of the placement platform 221e, so that the anti-diarrhea gasket 23 can be positioned, thereby making the position of the hole 231 always correspond to the flow channel portion 224, and in addition, the gap can be narrowed to prevent fluid from leaking. Furthermore, by locking the sleeve 21 and the connector 22 together, the end of the anti-diarrhea gasket 23 protruding from the placement platform 221e will extend into the front through hole 212c, and also tightly abut the front abutting surface 122 of the limiting flange 12 and the inner limiting wall surface 211f of the bottom wall 211a, so that fluid can be prevented from leaking from the end of the sleeve 21. In addition, when the sleeve 21 and the connector 22 are locked together, the anti-diarrhea gasket 23 is located between the sleeve 21 and the connector 22, and the thickness of the anti-diarrhea gasket 23 is configured, so that only the first threaded portion 213 and the second threaded portion 223 between the sleeve 21 and the connector 22 are in contact with each other, and the rest of the parts are not in contact, thereby avoiding scratches during the locking process.

[0042] The annular gasket 24 is embedded in the annular groove 221f, so that when the joint part 222 is connected to the water cooling system, scratches can be avoided and water overflow can be prevented.

[0043] See also Figure 5 and Figure 6 A second embodiment of the connecting pipeline device of the present invention is provided. The second embodiment is similar to the first embodiment, and the main difference lies in the positions of the first threaded portion 213 and the second threaded portion 223 on the kit 21 and the connecting member 22 respectively. The difference between the second embodiment and the first embodiment is further described below.

[0044] In the second embodiment, the connecting member 22 has a body 221 connected to the sleeve 21. The body 221 includes an annular base 221a having a first side 221b opposite to the sleeve 21 and a second side 221c facing the sleeve 21, an extension 221d extending from the periphery of the base 221a to the second side 221c, and a placement platform 221e formed by being concave from the second side 221c of the base 221a toward the first side 221b, the placement platform 221e is formed corresponding to the shape of the anti-diarrhea gasket 23, and the second threaded portion 223 is formed on the inner wall surface of the extension 221d.

[0045] The sleeve 21 comprises a sleeve body 211 surrounding the metal tube 1 and a stopper 212 disposed inside the sleeve body 211 . The sleeve body 211 comprises a surrounding wall 211 b surrounding the metal tube 1 . In detail, the surrounding wall 211b is annularly sleeved on the tube body 11 and has a front side surface 211d and a rear side surface 211e. The surrounding wall 211b protrudes toward the axis from its inner wall surface close to the rear side surface 211e to form the abutting portion 212. The abutting portion 212 defines a rear through hole 212b, and the cross-sectional area of ​​the rear through hole 212b is smaller than the cross-sectional area of ​​the limiting flange 12. The abutting portion 212 has a supporting surface 212a facing the limiting flange 12 and for the limiting flange 12 to abut. The limiting flange 12 includes a rear abutting surface 121 and a front abutting surface 122 located on opposite sides, wherein the rear abutting surface 121 is used to abut against the abutting surface 212a. In addition, the surrounding wall 211b also has an inner limiting wall 211f located on its inner wall surface close to the front side surface 211d and connected to the abutting surface 212a. The inner limiting wall 211f and the abutting surface 212a jointly define a front through hole 212c connected to the rear through hole 212b. The tube body 11 of the metal tube 1 can extend through the front through hole 212c and the rear through hole 212b, and the limiting flange 12 can extend through the front through hole 212c and abut against the card portion 212. In the second embodiment, the first threaded portion 213 is formed on the outer wall surface of the surrounding wall 211b close to the front side surface 211d, and the outer wall surface of the surrounding wall 211b close to the rear side surface 211e is provided with an embossed pattern. When the anti-diarrhea gasket 23 is placed on the placement platform 221e, one end of the anti-diarrhea gasket 23 will protrude outside the placement platform 221e, while the end located inside the placement platform 221e will be tightly against the wall surface of the placement platform 221e, thereby making the position of the hole 231 always correspond to the flow channel portion 224, and in addition, the gap can be narrowed to prevent fluid leakage. Furthermore, by locking the kit 21 and the connecting piece 22 with each other, the end of the anti-diarrhea gasket 23 protruding from the placement platform 221e will extend into the front through hole 212c, and also tightly abut against the front abutting surface 122 of the limiting flange 12 and the inner limiting wall 211f of the surrounding wall 211b, so that fluid can be prevented from leaking out from the end of the kit 21.

[0046] In addition, when the kit 21 and the connector 22 are locked with each other, the anti-diarrhea gasket 23 is located between the kit 21 and the connector 22, and the thickness of the anti-diarrhea gasket 23 is configured so that only the first threaded portion 213 and the second threaded portion 223 between the kit 21 and the connector 22 are in contact with each other, and the other parts are not in contact, thereby avoiding scratches during the locking process.

[0047] Specifically, the anti-diarrhea gasket 23 can be placed in the surrounding wall 211b and abut against the limiting flange 12, and the anti-diarrhea gasket 23 can be limited by the surrounding wall 211b to avoid sliding, and at the same time, the hole 231 of the anti-diarrhea gasket 23 is connected to the flow channel part 224 and the metal pipe 1. The extension part 221d can cover a part of the surrounding wall 211b, and is locked and fixed by the first threaded part 213 and the second threaded part 223, so that the anti-diarrhea gasket 23 is closely abutted against the placement platform 221e of the connecting member 22 and the front abutting surface 122 of the limiting flange 12, and the outer peripheral surface of the anti-diarrhea gasket 23 is closely abutted against the inner limiting wall surface 211f of the surrounding wall 211b to prevent fluid from leaking.

[0048] In summary, the present invention utilizes the structure of the cross-sectional shape and size of the aforementioned flow channel portion 224 to be the same from beginning to end, so that when the fluid flows into the external water-cooling heat dissipation system through the flow channel portion 224, the fluid pressure will not change excessively and the fluid pressure will tend to be stable, thereby avoiding the water-cooling pipeline in the water-cooling heat dissipation system from rupturing due to excessive fluid pressure, and thus the purpose of the present invention can be achieved.

[0049] The above are merely embodiments of the present invention and should not be used to limit the scope of the present invention.
