TECHNICAL FIELD
[0001] The utility model relates to the technical field of fastener, especially relates to a quick-mounting and quick-disassembling locking nut. BACKGROUND
[0002] The existing basin is usually provided with a faucet for adjusting water flow, and the fixing mode of the faucet is generally that the faucet is inserted into the basin first, and then the faucet is locked on the bottom wall of the basin through the threaded connection between the nut and the bottom of the faucet. However, the structure needs to rotate the nut in multiple circumferential directions during assembly, especially in the case of a large pipe joint length, the installer needs to consume a lot of time to complete the screwing operation, and the same problem of long time consumption is also faced during disassembly and maintenance, and the simple fixing mode is prone to cause the nut to loosen under the action of the torsional force for a long time, thereby causing the faucet to shake left and right. In addition, the existing nut is mostly installed in one direction, and tools are often needed during installation of the nut, and due to the limitation of the installation space, the operation process is relatively difficult, and if the installation is not proper, the faucet may not be fixed firmly, thereby affecting the stability during daily use.
[0003] Therefore, the present application is produced through the in-depth research of the present inventor on the above problems. SUMMARY
[0004] The utility model provides a quick-mounting and quick-disassembling locking nut, which aims to solve the problems of long time consumption during locking of the existing nut, one-way installation and easy loosening.
[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme:
[0006] A quick-mounting and quick-disassembling locking nut comprises a nut body in a cylindrical shape, a cavity penetrating in the axial direction is arranged in the middle part of the nut body, first and second thread blocks in a semicircular shape are correspondingly arranged on the two sides of the inner wall of the cavity, the first thread block and the second thread block are staggered in the axial direction, and an empty space for the pipeline to pass through is formed between the first thread block and the second thread block, ring parts in a ring shape are arranged on the top end and the bottom end of the nut body, a plurality of grooves penetrating and arranged at intervals are arranged on the top surface of the ring part, elastic anti-skid claws protruding from the top surface of the ring part are arranged in each groove, a plurality of wedge-shaped anti-skid teeth are arranged between adjacent grooves and arranged at intervals in the circumferential direction, a plurality of anti-skid protrusions are arranged between the two ring parts and arranged at intervals in the axial direction, and the anti-skid protrusions are fixedly connected with the nut body.
[0007] Further, the inner walls of the first and second thread blocks are respectively provided with first and second internal threads.
[0008] Furthermore, the aforementioned wedge-shaped anti-slip teeth include an inclined surface and a stop surface perpendicular to it.
[0009] Furthermore, the outer wall of the nut body is also provided with an indicator icon.
[0010] Furthermore, the lengths of the first threaded block and the second threaded block are 1 / 4 or 2 / 5 of the length of the nut body.
[0011] Furthermore, the nut body is made of plastic or metal.
[0012] As can be seen from the above description of the structure of this utility model, this utility model has the following advantages:
[0013] This invention utilizes a bidirectional nut design, allowing installers to easily push the nut in without needing to determine its orientation, significantly improving installation efficiency and reducing operational complexity. Furthermore, the addition of elastic anti-slip claws and wedge-shaped anti-slip teeth at both ends of the nut body effectively enhances the locking effect against the basin bottom, preventing loosening and greatly improving stability after tightening. In addition, anti-slip protrusions on the outer wall of the nut body allow installers to tighten it without tools, further improving work efficiency. Attached Figure Description

Detailed Implementation
[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0022] Reference Figures 1 to 6 A quick-release locking nut includes a cylindrical nut body 10. In this embodiment, the nut body 10 is made of plastic or metal. A cavity 11 extending along the axial direction is provided in the middle of the nut body 10. A first threaded block 12 and a second threaded block 13, each in a semi-arc shape, are respectively protruding from both sides of the inner wall of the cavity 11. The first threaded block 12 and the second threaded block 13 are staggered in the axial direction, and the inner walls of the first threaded block 12 and the second threaded block 13 are respectively provided with a first internal thread 121 and a second internal thread 131. In a horizontal state, referring to… Figure 4 A clearance 14 is formed between the first threaded block 12 and the second threaded block 13. This clearance 14 allows hot and cold water pipes and / or pull-out pipes to pass through, making it more versatile and improving the convenience of pipe threading during installation.
[0023] Reference Figures 1 to 6 The top and bottom ends of the nut body 10 are both provided with annular ring portions 20. The top surface of the ring portion 20 is provided with multiple spaced and through slots 21. Each slot 21 is provided with a deformable elastic anti-slip claw 22 protruding from the top surface of the ring portion 20. The elastic anti-slip claw 22 can be made of plastic. Between adjacent slots 21, there are multiple wedge-shaped anti-slip teeth 23 evenly distributed along the circumference. The wedge-shaped anti-slip teeth 23 include an inclined surface 231 and a stop surface 232 perpendicular to the inclined surface 231. The inclined surface 231 is in the same direction as the nut body 10 when locked. Between the two ring portions 20, there are also multiple anti-slip ridges 24 spaced along the axial direction. The anti-slip ridges 24 are fixedly connected to the nut body 10.
[0024] In use, first insert the faucet with the pipes installed into the basin. At this time, the external threaded section of the faucet is located under the basin. Since the nut body 10 in this embodiment adopts a two-way design, the installer does not need to determine the direction of the nut. Simply push the nut body 10 into the external threaded section of the faucet from under the basin at an angle. When the nut body 10 abuts against the bottom wall of the basin, the nut body 10 automatically returns to a horizontal position. At this time, the first internal thread 121 and the second internal thread 131 of the nut body 10 both grip the external threaded section of the faucet. Then, rotating the nut body 10 will lock it in place.
[0025] After the nut body 10 is tightened, the inclined surface 231 of the wedge-shaped anti-slip teeth 23 can increase the contact friction and provide a stronger fixing effect. At the same time, the anti-reverse surface 232 can effectively prevent the nut body 10 from rotating in the opposite direction when subjected to rotation or vibration, thereby enhancing the fixation of the nut body 10 to the bottom wall of the basin and preventing the faucet from loosening under the action of external torsional force, thus improving the stability and reliability of the connection of the nut body 10.
[0026] Furthermore, after the nut body 10 is tightened, the elastic anti-slip claw 22 deforms under external force and generates a reverse clamping force, further increasing the friction with the bottom wall of the basin and enhancing the locking effect. This ensures that the nut maintains a stable and secure state during prolonged use, preventing loosening. Simultaneously, the anti-slip protrusions 24 on the outer wall of the nut body 10 allow the installer to easily perform the tightening operation without tools, improving work efficiency and locking effectiveness.
[0027] Reference Figures 1 to 6 The outer side wall of the nut body 10 is also provided with an indicator icon 25, which is used to indicate the installation direction of the nut body 10, thereby providing users with a more intuitive installation and operation guide. In order to facilitate use in low light environments, the indicator icon 25 can be made of fluorescent material to ensure that it can still be clearly identified in dark conditions.
[0028] Reference Figures 1 to 6 The lengths of the first threaded block 12 and the second threaded block 13 are 1 / 4 or 2 / 5 of the length of the nut body 10, which significantly shortens the thread length on the threaded block. This not only reduces the time required to install the nut body 10, but also effectively reduces the processing cost of the thread.
[0029] 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.
