Detailed implementation mode

[0022] The following further describes the present utility model in combination with the embodiments shown in the accompanying drawings:

[0023] As Figures 1 to 7As shown in the figure, a joint assembly for facilitating the installation of a water inlet pipeline includes a joint body 1. One end of the joint body 1 is provided with a first interface 11, and a plugging and fixing structure 2 is arranged on the first interface 11. The plugging and fixing structure 2 includes a plugging and limiting housing 21, a limiting steel ball 22 and a metal spring 23. A first limiting boss 111 is arranged on the first interface 11. The inside of the plugging and limiting housing 21 is adapted to the first interface 11. A plurality of circular through holes 112 are formed in the side wall of the first interface 11, and a limiting steel ball 22 is arranged in each circular through hole 112. A second limiting boss 221 for squeezing the limiting steel ball 22 is further arranged inside the plugging and limiting housing 21. A metal spring 23 is also arranged between the first limiting boss 111 and the second limiting boss 221. A first end cover 3 is detachably connected inside the plugging and fixing structure 2. The first end cover 3 includes a first end cover body 31 and a first end cover boss 32. The first end cover boss 32 is arranged on one side of the first end cover body 31. An arc-shaped notch 321 adapted to the limiting steel ball 22 is arranged on the surface of the first end cover boss 32. A first thread notch 311 is arranged inside the first end cover body 31. After such a setting, whenever the interface at the bottom of the first end cover 3 with the first thread notch 311 or the bottom of other filters with the same diameter is inserted into the inside of the plugging and fixing structure 2, the bottom of the first end cover body 31 will press down the entire plugging and limiting housing 21. During this process, the metal spring 23 will deform, and the second limiting boss 221 inside the plugging and limiting housing 21 will gradually squeeze the limiting steel ball 22 to make it move inward. During the movement, the limiting steel ball 22 will be stuck inside the arc-shaped notch 321. At this time, the limiting steel ball 22 completes the fixation between the first end cover 3 and the first interface 11, and the clamping between the bottom of the first end cover body 31 and the plugging and limiting housing 21 prevents water from leaking out, avoiding the water leakage problem during rapid plugging.

[0024] In this embodiment, a water pipe joint assembly 6 is also detachably connected inside the first thread notch 311. The water pipe joint assembly 6 includes a water pipe joint body 61, a first support sleeve 62, and a threaded post 63. A first support sleeve 62 and a filtering element 7 are provided inside the water pipe joint body 61. The side wall of the water pipe joint body 61 is threadedly connected with a threaded post 63. One end of the water pipe joint body 61 is provided with a first thread boss 611. The end of the threaded post 63 can extend into the inside of the first support sleeve 62, and the first thread boss 611 is detachably connected to the inside of the first thread notch 311. After such a setting, whenever the first thread notch 311 cannot be connected to some pipelines without external threads, only need to connect the first thread boss 611 to the inside of the first thread notch 311, then rotate each threaded post 63 outwards. After rotating to the specified position, insert the external pipeline inside the water pipe joint body 61 and make its end firmly fit inside the first support sleeve 62. Then rotate each threaded post 63 inwards so that the end of each threaded post 63 clamps the pipeline. The filtering element 7 simply filters some large particle impurities to avoid clogging the entire water circuit.

[0025] In this embodiment, the other end of the joint body 1 is provided with a second interface 12, and a second end cover 4 is detachably connected to the end of the second interface 12. In this embodiment, the second end cover 4 has two different shapes. One of the second interfaces 12 is provided with a second thread boss 121. A second thread notch 41 is provided inside the second end cover 4. The second thread boss 121 is detachably connected to the inside of the second thread notch 41. A plurality of arc-shaped anti-slip grooves 42 are provided outside the second end cover 4. A sealing gasket 43 is also provided inside the end of the joint body 1 and the second end cover 4. After such a setting, whenever the second interface 12 of the joint body 1 is not in use, the second thread boss 121 can be connected to the inside of the second thread notch 41 to block the end. At this time, the entire joint body 1 only has one water inlet and one water outlet. The plurality of arc-shaped anti-slip grooves 42 are for increasing the friction force when the user disassembles and installs, to avoid being unable to unscrew due to slipping caused by water.

[0026] Another second interface 12 is provided with a second threaded boss 121. Inside the second end cap 4, there is a third threaded notch 44. The second threaded boss 121 is detachably connected to the inside of the third threaded notch 44. The horizontal cross-section of the second end cap 4 is hexagonal. A sealing gasket 43 is also provided at the end of the joint body 1 and inside the second end cap 4. After such a setting, whenever this end of the joint body 1 is not in use, the second threaded boss 121 can be connected to the inside of the third threaded notch 44 to block this end. At this time, the entire joint body 1 only has one water inlet and one water outlet. The horizontal cross-section of the second end cap 4 being hexagonal is for the user to be able to use a wrench during disassembly and assembly to avoid not being able to unscrew it due to water slippage.

[0027] In this embodiment, a third interface 13 is further provided on the side of the joint body 1. The end of the third interface 13 is detachably connected with a third end cap 5. Specifically, the third interface 13 is provided with a third threaded boss 131. The third end cap 5 includes a third end cap body 51, a third end cap boss 52, a silicone sealing ring 53 and an end cap plug 54. The third end cap boss 52 is arranged on one side of the third end cap body 51. Inside the third end cap body 51, there is a fourth threaded notch 511 and a filtering element 7. The fourth threaded notch 511 is detachably connected to the surface of the third threaded boss 131. Inside one end of the third end cap boss 52, there is also a silicone sealing ring 53. The end cap plug 54 is slidably connected to this end. The end of the end cap plug 54 can squeeze the silicone sealing ring 53. Inside the end cap plug 54, there are a number of anti-slip columnar bosses 541. The filtering element 7 includes a filtering support plate 71 and a filter screen 72. The filter screen 72 is arranged inside the filtering support plate 71. After such a setting, when the third interface 13 is used as a water outlet, the fourth threaded notch 511 on the third end cap body 51 is connected to the surface of the third threaded boss 131, and a filtering element 7 is also installed between them, which also plays a role in simply filtering some large-particle impurities to avoid blocking the entire water circuit. When used as a washing machine pipeline or other pipelines connected to the third end cap 5, only need to insert the external pipeline into the inside of the end cap plug 54. At this time, the outside of the end cap plug 54 will be squeezed by the inside of the third end cap boss 52. Coupled with a number of anti-slip columnar bosses 541 restricting it from falling off, and the silicone sealing ring 53 squeezed by the end of the end cap plug 54 ensures that there will be no water leakage.

[0028] The working principle and usage method of the present utility model:

[0029] The first interface 11 of the entire joint body 1 serves as the water inlet of the entire device, while the other two second interfaces 12 and third interfaces 13 serve as the water outlets of the entire device. Whenever the interface at the bottom of the first end cap 3 with the first thread notch 311 or the bottom of other filters of the same diameter is inserted into the interior of the plug-in fixing structure 2, the bottom of the first end cap body 31 will press down on the entire plug-in limiting housing 21. During this process, the metal spring 23 will deform, and the second limiting boss 221 inside the plug-in limiting housing 21 will gradually squeeze the limiting steel ball 22, causing it to move inward. During the movement, the limiting steel ball 22 will get stuck inside the arc notch 321. At this time, the limiting steel ball 22 has completed the fixation between the first end cap 3 and the first interface 11, and the clamping between the bottom of the first end cap body 31 and the plug-in limiting housing 21 prevents water from seeping out, avoiding the water leakage problem during rapid plugging;

[0030] When the first interface 11 is connected to a threaded water pipe or faucet, only need to install the external thread boss inside the first thread notch 311 of the first end cap body 31;

[0031] When the first interface 11 cannot be connected to some pipelines without external threads, only need to connect the first thread boss 611 of the water pipe joint body 61 to the inside of the first thread notch 311, then rotate each threaded post 63 outward. After rotating to the specified position, insert the external pipeline into the inside of the water pipe joint body 61 and make its end firmly fit inside the first support sleeve 62. Then rotate each threaded post 63 inward so that the end of each threaded post 63 clamps the pipeline, and the filter element 7 simply filters some large particle impurities to avoid clogging the entire water circuit;

[0032] When the second interface 12 is not in use, the second thread boss 121 can be connected to the inside of the second thread notch 41 to block this end. At this time, the entire joint body 1 only has one water inlet and one water outlet, and several arc-shaped anti-slip grooves 42 are for users to increase the friction force during disassembly and assembly, avoiding being unable to unscrew due to slipping caused by water;

[0033] When the third interface 13 serves as a water outlet, connect the fourth thread notch 511 on the third end cap body 51 to the surface of the third thread boss 131. A filter element 7 is also installed between them, which also simply filters some large particle impurities to avoid clogging the entire water circuit. When connecting to the third end cap 5 as a washing machine pipeline or other pipelines, only need to insert the external pipeline into the inside of the end cap plug 54. At this time, the outside of the end cap plug 54 will be squeezed inside the third end cap boss 52, and the several anti-slip columnar bosses 541 limit it from falling off, and the silicone rubber seal ring 53 that is squeezed against the end of the end cap plug 54 ensures that there will be no water leakage.
