[0031] It should be noted that if Figure 7 , Figure 8 and Fig. 9 As shown, the minimum distance between the limiting spring piece 141 and the first end face 25 refers to: the distance between the bottom end of the limiting spring piece 141 and the first end face 25; the maximum distance between the limiting block 23 and the first end face 25 refers to: the distance between the top end of the limiting block 23 and the first end face 25; the maximum distance is greater than the minimum distance, so that the limiting block 23 can abut against the limiting spring piece 141, play a limiting role on the limiting spring piece 141, thereby realizing the self-locking function.

[0032] In some embodiments, the interior of the faucet shell body 21 is provided with a through second inner hole 24, and part of the second inner hole 24 is provided with an internal thread 22. The outer periphery of the faucet core body 18 is fixedly connected with an external thread 15 that matches the internal thread 22. The external thread 15 is provided on the side of the mounting boss 14 facing the water outlet 16, and the faucet shell 2 and the faucet core 1 are connected by threads.

[0033] In some embodiments, the mounting plate 3 is provided with holes for the limiting block 23 and the faucet inner core body 18 to pass through respectively.

[0034] When the self-locking and anti-loosening faucet provided by the utility model is in use, after the faucet inner core 1 is inserted from the top of the mounting plate 3, the mounting boss 14 of the faucet inner core 1 abuts against the mounting plate 3, and the outer thread 15 of the faucet inner core 1 is located below the mounting plate 3, and then the inner thread 22 of the faucet outer shell 2 is threadedly connected with the outer thread 15 of the faucet inner core 1, so that the mounting plate 3 can be fixed between the faucet inner core 1 and the faucet outer shell 2, thereby realizing the installation and fixation of the self-locking and anti-loosening faucet. Preferably, the faucet inner core body 18 and the faucet outer shell body 21 can be a hollow cylindrical structure.

[0035] It should be noted that the mounting plate 3 can be a part of the drinking water equipment and form an integral structure with the drinking water equipment. Through the threaded cooperation between the faucet inner core 1 and the faucet outer shell 2, the entire self-locking and anti-loosening faucet can be fixedly installed on the mounting plate 3 of the drinking water equipment.

[0036] In some embodiments, the outer periphery of the faucet inner core body 18 is fixedly connected to the screwing boss 13 , and the screwing boss 13 is disposed on a side of the mounting boss 14 facing the water inlet 11 , and the screwing boss 13 is a polygonal structure.

[0037] In this embodiment, the faucet inner core 1 is rotated by screwing the screw boss 13, thereby realizing the threaded installation between the faucet inner core 1 and the faucet outer shell 2. The polygonal screw boss 13 is convenient for screwing installation.

[0038] In some embodiments, a fixing groove 12 is provided on the outer periphery of the faucet inner core body 18 close to the water inlet 11 .

[0039] In this embodiment, the water inlet 11 of the faucet inner core 1 is connected to the water outlet pipe of the drinking equipment, and the water outlet pipe of the drinking equipment can be clamped in the fixing groove 12 by a clamp or other structure. The fixing groove 12 is used to prevent the connection between the water outlet pipe of the drinking equipment and the water inlet 11 of the faucet inner core 1 from loosening, thereby achieving a tight connection between the water outlet pipe of the drinking equipment and the water inlet 11 of the faucet inner core 1.

[0040] In some embodiments, the inner diameter of the first inner hole 19 decreases from one end of the water inlet 11 to one end of the water outlet 16 , and a guide plate 17 is disposed in the first inner hole 19 near the water outlet 16 .

[0041] In this embodiment, the water of the drinking water device flows from the water inlet 11 of the inner core 1 of the faucet into the first inner hole 19, and flows out from the water outlet 16. The inner diameter of the first inner hole 19 decreases from the top water inlet 11 to the bottom water outlet 16, which plays a role in guiding the water flow and ensures the integrity of the water column; at the same time, the guide plate 17 arranged near the water outlet 16 in the first inner hole 19 increases the adhesion of water when the water stops flowing, and plays a role in preventing dripping after the water is taken. Preferably, the guide plate 17 can be a cross-shaped structure.

[0042] In some embodiments, a plane 232 and a slope 233 adjacent to the plane 232 are provided on the side of the limit block 23 away from the first end face 25, an arc surface 231 is provided on the side of the plane 232 away from the slope 233, and a limit surface 234 corresponding to the limit spring piece 141 is provided on the side of the limit block 23 away from the arc surface 231.

[0043] In this embodiment, since the mounting plate 3 is provided with a hole for the stopper 23 to pass through, when the faucet shell 2 and the faucet inner core 1 are threadedly connected and tightened, the stopper 23 provided on the first end surface 25 of the faucet shell 2 can pass through the mounting plate 3 and extend to the mounting boss 14 of the faucet inner core 1. When the screwing boss 13 is screwed, the screwing boss 13 drives the entire faucet inner core 1 to rotate. During the rotation of the mounting boss 14, the downwardly bent stopper 141 sequentially contacts the smooth arc surface 231, the plane 232, and the inclined surface 233. Since the stopper 141 itself has a certain elastic deformation, the stopper 141 will be tilted upward when passing through the inclined surface 233, so that the faucet inner core 1 can continue to rotate to be threadedly fastened with the faucet shell 2. Continue to screw. When the limiting spring piece 141 passes the inclined surface 233, the limiting spring piece 141 instantly returns to the initial state, so that the limiting spring piece 141 falls and hits the mounting plate 3, making a sound, indicating that it has been tightened, thereby achieving sound feedback when self-locking in place. The intuitive sound feedback mechanism informs the user that the faucet has been correctly installed, thereby improving the convenience of installation. At the same time, the distance between the bottom end of the limiting spring piece 141 and the first end face 25 is smaller than the distance between the top end of the limiting block 23 and the first end face 25, so that the limiting surface 234 of the limiting block 23 can abut against the limiting spring piece 141, thereby limiting the reverse rotation of the limiting spring piece 141, thereby preventing the limiting spring piece 141 and the entire faucet inner core 1 from reverse rotation, so that the faucet shell 2 and the faucet inner core 1 are tightly screwed together and fixed on the mounting plate 3 of the drinking water equipment, which has the effect of self-locking and anti-loosening, so that it can achieve automatic locking when tightening, avoid loosening, and prevent disassembly from the outside of the direct drinking water equipment, which can effectively solve the problem of loose faucet and easy external disassembly, thereby improving the use experience and safety of the direct drinking water equipment.

[0044] In some embodiments, a second end surface 26 is disposed at the other end of the faucet housing body 21 , and the water outlet 16 extends out of the faucet housing 2 through the second end surface 26 .

[0045] To sum up, the utility model provides a self-locking and anti-loosening water faucet, which completes self-locking through the cooperation of a limiting spring piece provided on the inner core of the water faucet and a limiting block provided on the outer shell of the water faucet. It not only has an effective self-locking mechanism, which can realize automatic locking when tightened to avoid loosening; it can also send out sound feedback when self-locking is in place, and inform the user through an intuitive sound feedback mechanism that the water faucet has been correctly installed, thereby improving the convenience of installation; at the same time, it can also prevent disassembly from the outside of the direct drinking water equipment, which can effectively solve the problem of the water faucet loosening and easy disassembly from the outside, thereby improving the use experience and safety of the direct drinking water equipment.
