[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] like Figures 1 to 7 The quick-release locking nut for a faucet includes a pressure ring 1 and a connector body 2, which form a channel for inserting the threaded tube of the faucet. The connector body 2 can rotate circumferentially around the axis of the pressure ring 1. The inner walls of the insertion holes of the pressure ring 1 and the connector body 2 are respectively provided with a first threaded section 3 and a second threaded section 4. Both the first threaded section 3 and the second threaded section 4 are radially protruding arc-shaped threaded sections, and the arc of a single threaded section does not exceed 1 / 2 of the circumferential threaded section. In the initial state, rotating the connector body 2 keeps the second threaded section 4 longitudinally aligned with the first threaded section 3 of the pressure ring 1 so that the threaded tube can be inserted longitudinally. In the installation state, rotating the connector body 2 causes the second threaded section 4 to be misaligned with the first threaded section 3 of the pressure ring 1 to a locking position (the locking position is not a fixed point, but can be achieved by rotating so that the threaded tube is subjected to radial extrusion force and enters the engagement area, maintaining a fixed engagement with the two threaded sections). The radial extrusion of the threaded tube limits and locks it within the engagement area formed by the two threaded sections. This application is not limited to faucets; other connectors with threaded tube structures are also applicable.

[0024] Through an innovative complementary threaded segment dynamic engagement structure, locking / unlocking can be completed by simply rotating the connector body 2180° after the threaded tube is inserted, eliminating the need for multiple rotations of the traditional nut and improving rapid assembly and disassembly efficiency. The complete circumferential thread profile formed by the misalignment of the complementary threaded segments ensures a uniform distribution of radial extrusion force on the threaded tube in the engagement area, resulting in a stable and reliable connection. This application is particularly suitable for scenarios such as commercial kitchens and public bathrooms where frequent disassembly and assembly are required. While ensuring the sealing of the connection, it significantly improves construction and maintenance efficiency. In this embodiment, after the pressure ring 1 is installed, it is erected and pressed onto the faucet. One end of the connector body 2 relative to the pressure ring 1 is connected to a flexible hose or rigid pipe. The specific connection method is designed according to production requirements, which is existing technology and not the focus of this application, so it is not described in detail.

[0025] The arc of the first threaded segment 3 and the second threaded segment 4 is 1 / 2 of the circumferential threaded segment; in the mounted state, the axial projections of the first threaded segment 3 and the second threaded segment 4 are complementary, and the first threaded segment 3 and the second threaded segment 4 combine to form a complete circumferential threaded segment profile; the arc of the first threaded segment 3 and the second threaded segment 4 is not limited to 1 / 2 of the circumferential threaded segment, but can also be 1 / 4 of the circumferential threaded segment; according to the actual situation, the size ratio is adjusted, so that the threaded pipe can be coaxially positioned between the first threaded segment 3 and the second threaded segment 4 after the two are misaligned.

[0026] The area outside the first threaded segment 3 and the second threaded segment 4 on the inner wall of the insertion hole forms an avoidance area 5, and the inner diameter of the avoidance area 5 is greater than the inner diameter of the threaded segment, which is used to avoid the threaded pipe in the initial state so that it can be longitudinally inserted; in the embodiment, the enlarged inner diameter of the avoidance area 5 ensures that there is no frictional resistance when the threaded pipe is inserted, and compared with the full-threaded mode, it does not need to be screwed to the bottom, and it is convenient to disassemble and assemble.

[0027] The joint body 2 and the compression ring 1 are coaxially nested to form a detachable connection structure. The compression ring 1 is sleeved on the upper part of the joint body 2, and the inner wall of the compression ring 1 is provided with a limiting step 6 located at the lower end face of the first threaded segment 3, and the limiting step 6 abuts against the upper end of the joint body 2.

[0028] The outer wall of the upper part of the joint body 2 is provided with at least one annular clamping groove 7 in the longitudinal direction, and the inner wall of the compression ring 1 is provided with an elastic clamping block 8 which can be limited in the annular clamping groove 7, and the elastic clamping block 8 can move along the circumferential path of the annular clamping groove 7.

[0029] The limiting step 6 is provided with a blocking block 9 located outside the first threaded segment 3, and the blocking block 9 is circumferentially misaligned with the first threaded segment 3 and located in the avoidance area 5; the two side end portions of the second threaded segment 4 can abut against the blocking block 9 to realize circumferential limiting when the second threaded segment 4 is circumferentially rotated with the joint body 2.

[0030] The end of the compression ring 1 away from the joint body 2 is provided with a ratchet surface 10, which is matched with the ratchet surface 10 on one side of the faucet with a threaded pipe.

[0031] The basic principle, main features and advantages of the utility model are shown and described above, and those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and the description in the specification are only preferred examples of the utility model and are not used to limit the utility model; various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed, and the scope of protection of the utility model is defined by the appended claims and their equivalents.
