DETAILED DESCRIPTION

[0024] The technical scheme of the utility model will be described below in connection with the drawings. Obviously, the described embodiments are part of the embodiments of the utility model and not all the embodiments.

[0025] Reference Figures 1 to 5 , a quick dismounting locking nut, including detachable connection's rotary main body 10 and fixed main body 20, in this embodiment, rotary main body 10 and fixed main body 20 can be made of plastic or metal material, rotary main body 10 is cylindrical, and the middle part of rotary main body 10 is provided with a cavity penetrating along the axial direction, and the inside of rotary main body 10 is provided with a ring 11, the inner peripheral wall of ring 11 is provided with a first threaded part, and the outer peripheral wall of ring 11 is provided with two positioning columns 112, the ends of the two positioning columns 112 are fixedly connected with rotary main body 10, and the outer peripheral wall of ring 11 and the inner peripheral wall of rotary main body 10 have a gap, and fixed main body 20 is circular, and it includes a friction part 21 and a locking part 22 for entering the gap, the top surface of friction part 21 is provided with annularly distributed friction units, the middle part of the friction unit is provided with a through hole 23 penetrating friction part 21 and locking part 22, and the inner side wall and the bottom of locking part 22 are respectively provided with a second threaded part 221 and at least one positioning point 224.

[0026] When being in the first state, the positioning point 224 abuts against one of the positioning columns 112, and at this time, the first threaded part 111 and the second threaded part 221 are staggered on the axis; when being in the second state, the positioning point 224 abuts against the other positioning column 112, and at this time, the first threaded part 111 and the second threaded part 221 are vertically arranged.

[0027] During installation, first screw the nut into the open state (i.e., the second state). At this time, insert the faucet with the hose connected to it into the hole of the basin. Since there is no thread on one side of the nut in the open state, the hose can be easily passed through the nut. Then move the nut upward so that the top surface of the nut friction part 21 abuts against the bottom wall of the basin. Then screw the rotating body 10 so that the positioning point 224 abuts against one of the positioning pins 112. At this time, it is in the installation state (i.e., the first state), thus realizing the quick installation of the nut. When disassembling, simply rotate the rotating body 10 half a turn in the opposite direction to make the nut open, and then pull it down to realize the quick disassembly of the nut.

[0028] Reference Figures 1 to 4 The outer wall of the locking part 22 is provided with a positioning ring groove 222. Two positioning guide grooves 223 communicating with the positioning ring groove 222 are provided on both sides of the positioning ring groove 222. The inner peripheral wall of the rotating body 10 is provided with two positioning buckles 13 for entering the positioning guide grooves 223. During installation, the positioning buckles 13 of the rotating body 10 can enter the positioning ring groove 222 through the positioning guide grooves 223, thereby ensuring the precise docking of the rotating body 10 and the fixed body 20 during the installation process and avoiding jamming or misalignment due to inaccurate positioning.

[0029] Reference Figures 1 to 4 The first threaded portion 111 and the second threaded portion 221 are respectively the first internal thread and the second internal thread. Both the first internal thread and the second internal thread are semi-arc-shaped, and there is a gap in the middle of both the first internal thread and the second internal thread. With this setting, the threads can be easily aligned and staggered, so that they can be quickly installed or disassembled.

[0030] Reference Figures 1 to 4 The friction unit consists of several wedge-shaped anti-slip teeth 211 arranged in a clockwise direction. Each wedge-shaped anti-slip tooth 211 is composed of an inclined surface 212 and a stop surface 213 perpendicular to it. After installation, the several wedge-shaped anti-slip teeth 211 of the friction part 21 are tightly abutted against the bottom wall of the basin. When locked, the friction force with the bottom wall of the basin can be increased, ensuring that the nut will not loosen under vibration or external force.

[0031] Reference Figures 1 to 4The outer peripheral wall of the locking part 22 is also provided with an annular groove 225, and a sealing ring 2251 is provided in the annular groove 225. This setting further improves the sealing and anti-loosening performance of the locking nut. The outer peripheral wall of the rotating body 10 is surrounded by multiple strip-shaped grooves 14 arranged axially at intervals. The bottom end of the strip-shaped grooves 14 extends downward from the rotating body 10. This increases the friction during installation, making it easier for users to operate and install. Especially when manually disassembling, the strip-shaped grooves 14 can increase the gripping force, greatly improving the user experience. In addition, the outer peripheral wall of the rotating body 10 is also provided with an indicator icon 15, which can show the opening and closing direction of the nut. This provides users with a more intuitive installation and operation guide. In order to facilitate the installation of the rotating body 10 in a dark environment, the indicator icon 15 can also be made of fluorescent material, so that it can still be clearly seen in a dark environment.

[0032] It should be noted that this utility model can be applied not only to locking basin faucets, but also to pull-out faucets, making it more versatile.

[0033] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
