Description

Technical Field

[0001] The present invention relates to the technical field of faucets, and in particular to a faucet stable docking device. Background Art

[0002] A faucet belongs to a branch of valves and is often used to control the flow of water. When installing a faucet, it is necessary to dock and install the faucet with the water delivery pipe of the tap water delivery pipeline.

[0003] A patent with the patent publication number CN107387912A discloses an intelligent faucet that is easy to install and stably docked, including a faucet. One end of the faucet is fixedly connected with a water inlet pipe. The faucet is communicated with the water inlet pipe. A water delivery pipe is sleeved on the water inlet pipe. A sealing sleeve is sleeved on the water inlet pipe. The outer side wall of the sealing sleeve abuts against the inner wall of the water delivery pipe. A hollow block is sleeved on the water inlet pipe. Slide rails are embedded at the upper and lower ends on one side of the hollow block. Sliders are slidably connected in the slide rails. The opposite sides of the two sliders are respectively movably connected with the inner walls of the two slide rails through telescopic rods.

[0004] The above patent completes the installation of the faucet by connecting the water inlet pipe on the faucet with the water delivery pipe. However, when the water inlet pipe and the water delivery pipe are installed, it is necessary to make the sealing sleeve on the water inlet pipe contact the inner wall of the water delivery pipe. The resistance of the water delivery pipe sleeved on the water inlet pipe is large, resulting in the docking and installation operation of the faucet being time-consuming and laborious, and the docking efficiency of the faucet being low. In view of this, we have designed a faucet stable docking device that can complete the quick docking of the faucet by rotating the water inlet pipe half a turn. Summary of the Invention

[0005] In order to overcome the disadvantages that when installing a faucet in the prior art, the resistance of the water delivery pipe sleeved on the water inlet pipe is large, and the docking and installation operation of the faucet is time-consuming and laborious, the present invention provides a faucet stable docking device that can complete the quick docking of the faucet by rotating the water inlet pipe half a turn.

[0006] A faucet stable docking device includes a retaining ring, a water inlet pipe and external threads. The water delivery pipe is the water delivery pipe of the tap water pipeline and is fixed on the wall. A faucet is placed on the right side of the water delivery pipe. The water inlet pipe is bolted to the water inlet of the faucet. External threads are engraved on the upper and lower parts of the outer wall of the side of the water inlet pipe away from the faucet. A retaining ring is connected to the outer wall of the water inlet pipe near the external threads. The device further includes a docking mechanism and a locking mechanism. The docking mechanism is provided on the water inlet pipe and is used for quickly and stably docking the water delivery pipe and the water inlet pipe. The locking mechanism is provided on the water inlet pipe and is used for locking the docked water delivery pipe and water inlet pipe.

[0007] Optionally, the docking mechanism includes a gasket, an internal thread, and a bottom ring. A gasket is movably sleeved on the water inlet pipe. The gasket is located between the external thread and the retaining ring. A bottom ring is installed at the outer wall pipe orifice of the water delivery pipe. Internal threads are evenly engraved on the front and rear parts near the pipe orifice of the inner wall of the water delivery pipe. The external thread of the water inlet pipe is matched with the internal thread of the water delivery pipe.

[0008] Optionally, the locking mechanism includes a resisting column, a first spring, a positioning column, a protective sleeve, and a fixing block. A fixing block is connected to the upper side of the water inlet pipe. A protective sleeve is installed on the left side of the fixing block. A resisting column is connected to the right side inside the protective sleeve. A positioning column is slidably connected to the left side inside the protective sleeve. Unlocking holes are opened on the upper and lower sides of the left part of the positioning column and the protective sleeve. A first spring is connected between the positioning column and the resisting column. A positioning hole is opened at the upper front part of the right part of the bottom ring. When the positioning column rotates to correspond to the positioning hole, the positioning column is inserted into the positioning hole.

[0009] Optionally, it further includes a filtering mechanism for filtering the water entering the water inlet pipe. The filtering mechanism includes a filter screen and positioning blocks. Positioning blocks are clamped on the upper and lower parts of one side near the pipe orifice of the inner wall of the water inlet pipe. A filter screen is connected between the positioning blocks. The filter screen is completely attached to the inner wall of the water inlet pipe.

[0010] Optionally, it further includes a prompting mechanism for prompting that the positioning column is inserted into the positioning hole. The prompting mechanism includes a prompting cylinder, a supporting block, and an extrusion assembly. A supporting block is installed on the upper part of the water inlet pipe. The supporting block is located inside the fixing block. A prompting cylinder is rotatably connected to the upper part of the supporting block. The prompting cylinder is rotatably connected to the fixing block. The right wall of the prompting cylinder is evenly divided into four equal parts. Three-quarters of the color of the right wall of the prompting cylinder is red, and one-quarter of the color of the right wall of the prompting cylinder is green. When it is observed that the green part on the prompting cylinder just rotates one week, it indicates that the positioning column is inserted into the positioning hole. An extrusion assembly for extruding the prompting cylinder to rotate is provided on the positioning column.

[0011] Optionally, the extrusion assembly includes a connecting rod, a sliding rod, and small ball bearings. A connecting rod is connected to the right side of the positioning column. The connecting rod is slidably connected to the resisting column. A sliding rod is connected to the right side of the connecting rod. The sliding rod is located inside the prompting cylinder. The sliding rod is rotatably connected to the prompting cylinder. A small ball bearing is rotatably connected to the right side of the sliding rod. A curve groove is opened inside the prompting cylinder. The small ball bearing of the sliding rod moves in the curve groove on the prompting cylinder.

[0012] Optionally, it further includes a leak-proof mechanism for preventing water from leaking out of the connection part between the water inlet pipe and the faucet. The leak-proof mechanism includes a sliding sleeve and a sealing ring. A sliding sleeve is slidably connected to the water inlet pipe. The sliding sleeve moves to the right and sleeves on the connection part between the water inlet pipe and the faucet. A sealing ring is connected to the inner wall of the sliding sleeve.

[0013] Optionally, it further includes a locking mechanism for locking the positioning post after the positioning post is inserted into the positioning hole. The locking mechanism includes a locking rod and a second spring. The locking rod is slidably connected to the bottom ring. The locking rod is inserted into the positioning hole. The second spring is wound around the locking rod. The inner and outer ends of the second spring are respectively connected to the locking rod and the bottom ring.

[0014] The present invention has the following advantages:

[0015] 1. When the external thread of the water inlet pipe corresponds to the internal thread of the water delivery pipe, rotate the water inlet pipe half a turn. The water inlet pipe moves spirally to the left and is inserted into the water delivery pipe. In this way, the water inlet pipe and the water delivery pipe can be docked by rotating the water inlet pipe half a turn, which is beneficial to quickly complete the installation and docking of the faucet.

[0016] 2. When docking the water inlet pipe and the water delivery pipe, a gasket can be used to improve the sealing performance of the connection part between the water inlet pipe and the water delivery pipe, and the friction between the gasket and the bottom ring can be utilized to stably dock the water inlet pipe and the water delivery pipe.

[0017] 3. When the positioning post rotates to correspond to the positioning hole, the elastic force of the first spring causes the positioning post to move to the left and be inserted into the positioning hole, thereby enhancing the stability of the docking between the water inlet pipe and the water delivery pipe.

[0018] 4. When water flows between the water inlet pipe and the water delivery pipe, the water flows into the water inlet pipe through the filter screen. In this way, the water can be filtered, and the impurities in the water can be intercepted, which is beneficial to providing clean water for people.

[0019] 5. When the green part on the prompt cylinder just rotates one week, it reminds people that the docking of the water inlet pipe and the water delivery pipe is completed, thereby reminding people to stop rotating the water inlet pipe and avoiding excessive rotation of the water inlet pipe on the water delivery pipe, which is beneficial to the stable docking of the water inlet pipe and the water delivery pipe.

[0020] 6. After the water inlet pipe is bolted to the faucet, by pulling the sliding sleeve to the right, the sliding sleeve and the sealing ring can seal the bolted part between the water inlet pipe and the faucet, which is beneficial to improving the sealing performance and leak-proof performance of the faucet.

[0021] 7. When the unlocking hole on the positioning post corresponds to the locking rod, the second spring resets to cause the locking rod to move inward and insert into the unlocking hole on the positioning post, so as to fix the positioning post, which is beneficial to enhancing the stability of the faucet after docking.

Detailed implementation manners

[0036] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrating the present application and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually those in conventional experiments.

[0037] Example 1

[0038] A faucet stable docking device, as Figure 1 , Figure 2 and Figure 3 shown, includes a retaining ring 2, a water inlet pipe 21, an external thread 22, a docking mechanism 3 and a locking mechanism 4. The water delivery pipe 23 is the water delivery pipe 23 of the tap water pipeline, and the water delivery pipe 23 is fixed on the wall. A faucet 1 is placed on the right side of the water delivery pipe 23. The water inlet pipe 21 is bolted to the water inlet of the faucet 1. External threads 22 are engraved on both the upper and lower parts of the outer wall of the side of the water inlet pipe 21 away from the faucet 1. A retaining ring 2 is fixedly connected to the side of the outer wall of the water inlet pipe 21 near the external thread 22. A docking mechanism 3 is provided on the water inlet pipe 21, and a locking mechanism 4 is provided on the water inlet pipe 21.

[0039] As Figure 1 and Figure 4 shown, the docking mechanism 3 includes a gasket 31, an internal thread 32 and a bottom ring 33. The gasket 31 is movably sleeved on the water inlet pipe 21. The gasket 31 is located between the external thread 22 and the retaining ring 2. A bottom ring 33 is welded to the outer wall pipe orifice of the water delivery pipe 23. Internal threads 32 are evenly engraved on both the front and rear parts near the pipe orifice of the inner wall of the water delivery pipe 23. The external thread 22 of the water inlet pipe 21 cooperates with the internal thread 32 of the water delivery pipe 23.

[0040] As Figure 1 , Figure 3 , Figure 5 and Figure 6 shown, the locking mechanism 4 includes a resisting column 41, a first spring 42, a positioning column 43, a protective sleeve 44 and a fixing block 45. A fixing block 45 is welded to the upper side of the water inlet pipe 21. A protective sleeve 44 is fixedly connected to the left side of the fixing block 45. A resisting column 41 is fixedly connected to the right side inside the protective sleeve 44. The positioning column 43 is slidably connected to the left side inside the protective sleeve 44. Unlocking holes are opened on both the upper and lower sides of the left part of the positioning column 43 and the protective sleeve 44. The first spring 42 is connected between the positioning column 43 and the resisting column 41. A positioning hole 46 is opened on the upper front part of the right side of the bottom ring 33. When the positioning column 43 rotates to correspond to the positioning hole 46, the positioning column 43 is inserted into the positioning hole 46.

[0041] When it is necessary to dock the faucet 1 with the water delivery pipe 23 of the tap water pipe, this faucet stable docking device can be used. First, people align the external thread 22 of the water inlet pipe 21 with the internal thread 32 of the water delivery pipe 23, and rotate the water inlet pipe 21 half a turn. Under the cooperation of the external thread 22 and the internal thread 32, the water inlet pipe 21 moves spirally to the left and inserts into the water delivery pipe 23. By rotating the water inlet pipe 21 half a turn, the water inlet pipe 21 and the water delivery pipe 23 can be docked, which is beneficial to quickly complete the installation and docking of the faucet 1. The spiral leftward movement of the water inlet pipe 21 drives the gasket 31 and the retaining ring 2 to move leftward. Subsequently, the gasket 31 moves leftward until it contacts the bottom ring 33, and the retaining ring 2 continues to move leftward to squeeze the gasket 31 against the bottom ring 33 tightly. In this way, the gasket 31 can be used to improve the sealing performance of the connection part between the water inlet pipe 21 and the water delivery pipe 23, and the friction between the gasket 31 and the bottom ring 33 can be utilized to stably dock the water inlet pipe 21 and the water delivery pipe 23. When the water inlet pipe 21 moves spirally leftward and approaches the water delivery pipe 23, the water inlet pipe 21 drives the fixed block 45, the protective sleeve 44, the resisting column 41, the first spring 42, and the positioning column 43 to move spirally leftward until they contact the bottom ring 33. The continuous spiral leftward movement of the water inlet pipe 21 causes the positioning column 43 to contract under the force on the bottom ring 33, and the first spring 42 is compressed. And the elastic force of the first spring 42 makes the positioning column 43 abut against the bottom ring 33. When the positioning column 43 rotates to correspond to the positioning hole 46, the elastic force of the first spring 42 makes the positioning column 43 move leftward and insert into the positioning hole 46. In this way, the stability of the docking between the water inlet pipe 21 and the water delivery pipe 23 can be enhanced. When it is necessary to disconnect the docking between the water inlet pipe 21 and the water delivery pipe 23, an external tool is used to insert into the unlocking hole on the positioning column 43 and pull out the positioning column 43. Subsequently, the water inlet pipe 21 is reversed, so that the water inlet pipe 21 is separated from the water delivery pipe 23. Then the gasket 31 is separated from the bottom ring 33, and the fixed block 45 and the protective sleeve 44 are reset. Then the external tool is taken away, and under the reset action of the first spring 42, the positioning column 43 is reset.

[0042] Embodiment 2

[0043] On the basis of Embodiment 1, as Figure 3 、 Figure 7 and Figure 8 shown, it further includes a filtering mechanism 5. The filtering mechanism 5 includes a filter screen 51 and a positioning block 52. The upper and lower parts of one side of the inner wall of the water inlet pipe 21 near the pipe orifice are both clamped with positioning blocks 52, and the filter screen 51 is connected between the positioning blocks 52. The filter screen 51 is completely attached to the inner wall of the water inlet pipe 21.

[0044] When the water inlet pipe 21 and the water delivery pipe 23 are butted, the filter screen 51 is located at the connection of the water inlet pipe 21 and the water delivery pipe 23. When water flows between the water inlet pipe 21 and the water delivery pipe 23, the water flows into the water inlet pipe 21 through the filter screen 51. In this way, the water can be filtered and impurities in the water can be intercepted, which is beneficial to providing clean water for people. When the filter screen 51 needs to be replaced, on the basis of separating the water inlet pipe 21 and the water delivery pipe 23, a new filter screen 51 can be replaced. In this way, it is beneficial to continuously filter the water.

[0045] As Figure 1 , Figure 9 , Figure 10 and Figure 11 shown, it further includes a prompting mechanism 6. The prompting mechanism 6 includes a connecting rod 61, a sliding rod 62, small balls 63, a prompting cylinder 64 and a supporting block 65. A connecting rod 61 is fixedly connected to the right side of the clamping column 43. The connecting rod 61 is slidably connected to the resisting column 41. A sliding rod 62 is welded to the right side of the connecting rod 61. A supporting block 65 is fixedly connected to the upper part of the water inlet pipe 21. The supporting block 65 is located inside the fixing block 45. The prompting cylinder 64 is rotatably connected to the upper part of the supporting block 65. The prompting cylinder 64 is rotatably connected to the fixing block 45. The sliding rod 62 is located inside the prompting cylinder 64. The sliding rod 62 is rotatably connected to the prompting cylinder 64. A small ball 63 is rotatably connected to the right side of the sliding rod 62. A curved groove is opened inside the prompting cylinder 64. The small ball 63 of the sliding rod 62 moves in the curved groove on the prompting cylinder 64. The right wall of the prompting cylinder 64 is evenly divided into four equal parts. Three-quarters of the right wall of the prompting cylinder 64 is red in color, and one-quarter of the right wall of the prompting cylinder 64 is green in color. When it is observed that the green part on the prompting cylinder 64 just rotates one week, it indicates that the clamping column 43 is inserted into the clamping hole 46.

[0046] During the process of rotating the water inlet pipe 21, when the clamping column 43 moves leftward and is inserted into the clamping hole 46, the clamping column 43 causes the connecting rod 61 to move leftward, thereby causing the sliding rod 62 to move leftward. The sliding rod 62 moving leftward causes the small ball 63 to move leftward. The small ball 63 moving leftward presses the curved groove on the prompting cylinder 64, thereby causing the prompting cylinder 64 to rotate. When the green part on the prompting cylinder 64 just rotates one week, it reminds people that the docking of the water inlet pipe 21 and the water delivery pipe 23 is completed, thereby reminding people to stop rotating the water inlet pipe 21. In this way, it can avoid the water inlet pipe 21 rotating excessively on the water delivery pipe 23, which is beneficial to the stable docking of the water inlet pipe 21 and the water delivery pipe 23. When the clamping column 43 resets, the clamping column 43 causes the connecting rod 61 to move rightward, thereby causing the sliding rod 62 to move rightward, and further causing the small ball 63 to move rightward. The small ball 63 moving rightward presses the curved groove on the prompting cylinder 64, thereby causing the prompting cylinder 64 to reverse and reset.

[0047] As Figure 1 , Figure 3 and Figure 12As shown, it further includes a leak-proof mechanism 7. The leak-proof mechanism 7 includes a sliding sleeve 71 and a sealing ring 72. The sliding sleeve 71 is slidably connected to the water inlet pipe 21. The sliding sleeve 71 moves to the right and sleeves on the bolted part of the water inlet pipe 21 and the faucet 1. The sealing ring 72 is fixedly connected to the inner wall of the sliding sleeve 71.

[0048] After the water inlet pipe 21 and the faucet 1 are bolted, pull the sliding sleeve 71 to the right, so that the sliding sleeve 71 and the sealing ring 72 seal the bolted part of the water inlet pipe 21 and the faucet 1, which is beneficial to improving the sealing performance and leak-proof performance of the faucet 1.

[0049] As Figure 1 and Figure 13 As shown, it further includes a locking mechanism 8. The locking mechanism 8 includes a locking rod 81 and a second spring 82. The locking rod 81 is slidably connected to the bottom ring 33. The locking rod 81 is inserted into the positioning hole 46. The second spring 82 is wound around the locking rod 81. The inner and outer ends of the second spring 82 are respectively connected to the locking rod 81 and the bottom ring 33.

[0050] During the process of the positioning post 43 being inserted into the positioning hole 46, when the positioning post 43 moves to contact the locking rod 81, it squeezes the locking rod 81 to move outwards, and the second spring 82 is compressed. When the unlocking hole on the positioning post 43 corresponds to the locking rod 81, the second spring 82 resets to make the locking rod 81 move inwards, and makes the locking rod 81 insert into the unlocking hole on the positioning post 43. In this way, the positioning post 43 can be fixed after it is inserted into the positioning hole 46, which is beneficial to enhancing the stability after the faucet is butted. When it is necessary to separate the positioning post 43 from the positioning hole 46, just pull out the locking rod 81.

[0051] The above embodiments are only the preferred embodiments of the present invention, and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
