Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to a double anti-loosening locking nut. Background Technology

[0002] Existing washbasins typically come with faucets that regulate water flow. These faucets are usually secured by inserting them into the basin and then connecting them to the threaded bottom of the faucet with a nut, locking them to the basin's base. However, this simple method of securing the faucet is prone to loosening under prolonged torsional forces, leading to faucet wobbling. Furthermore, existing nuts often require tools for installation, and space constraints can make the process difficult. Improper installation can result in an unstable faucet, affecting its stability during daily use.

[0003] In view of this, the inventor conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

[0004] This utility model provides a double anti-loosening locking nut, which aims to solve the problems of nuts being prone to loosening under long-term torsional force and being difficult to install.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A double anti-loosening locking nut includes a nut body, which is a cylindrical structure with rounded corners. The nut body has a cavity extending through the center along the axial direction. With the axial direction of the nut body as the vertical direction, a ring wall extends inward from the upper end of the nut body. A ring wall extends downward from the inner side wall of the ring wall. A through hole communicating with the cavity is formed in the center of the ring wall. The inner circumferential wall of the ring wall is provided with a metal internal thread. A plurality of friction units are protruding from the top surface of the ring wall and evenly distributed along the circumference. An elastic anti-slip claw protruding from the top surface of the ring wall and deformable is provided between adjacent friction units. A clearance slot is also opened at one corner of the top surface of the ring wall. The clearance slot penetrates the ring wall and the ring wall and communicates with the cavity.

[0007] Furthermore, the aforementioned friction unit includes a plurality of wedge-shaped anti-slip teeth evenly distributed circumferentially, each of the aforementioned wedge-shaped anti-slip teeth consisting of an inclined surface and a stop surface perpendicular to it.

[0008] Furthermore, the aforementioned friction unit includes a plurality of arrow-shaped protrusions evenly distributed circumferentially, with the arrowheads of the plurality of arrow-shaped protrusions pointing in the same direction.

[0009] Furthermore, the outer peripheral wall of the nut body is provided with an anti-slip unit.

[0010] Furthermore, the aforementioned anti-slip unit includes a plurality of anti-slip protrusions and / or anti-slip grooves evenly distributed radially.

[0011] Furthermore, the aforementioned anti-slip unit includes multiple evenly spaced anti-slip protrusions.

[0012] Furthermore, the upper and lower parts of the outer surface of the aforementioned metal internal thread are provided with two connecting protrusions, which are embedded in the aforementioned annular wall.

[0013] Furthermore, the inner wall of the nut body is provided with a plurality of axially extending reinforcing ribs, one end of which is connected to the annular wall and the other end extends to the lower end of the nut body.

[0014] Furthermore, the length of the aforementioned annular wall is 1 / 4 or 2 / 5 of the length of the aforementioned nut body.

[0015] Furthermore, the nut body is made of plastic or metal.

[0016] As can be seen from the above description of the structure of this utility model, this utility model has the following advantages:

[0017] Firstly, this utility model features a nut body with rounded corners and a surrounding wall at the top. Multiple friction units are evenly distributed circumferentially on the top surface of the surrounding wall, and elastic, deformable anti-slip claws protrude from the top surface of the surrounding wall between adjacent friction units. This achieves a double-locking effect on the nut, preventing the nut body from loosening under external torsional forces and improving the stability and reliability of the nut body connection. Furthermore, because the nut body is rounded, workers can easily perform the locking operation without tools, resulting in higher efficiency and better locking effect.

[0018] Secondly, the outer peripheral wall of the nut body of this utility model is also provided with an anti-slip unit, which can effectively enhance the grip and friction of the nut body during use, improve the worker's control when tightening the nut body, avoid slippage or slippage, and significantly improve the work efficiency of nut tightening.

[0019] Thirdly, this utility model has a clearance groove on the nut body, which makes it easier for hot and cold water pipes and / or pull-out pipes to pass through, making it more versatile and easier to install. Attached Figure Description

[0028] 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.

[0029] Reference Figures 1 to 4 A double anti-loosening locking nut includes a nut body 10. In this embodiment, the nut body 10 has a rounded rectangular cylindrical structure. Of course, its shape can also be varied, such as pentagon, hexagon, etc. Its material can be plastic or metal. The nut body 10 has a cavity extending through the center along the axial direction. With the axial direction of the nut body 10 as the up and down direction, a ring wall 11 extends inward from the upper end of the nut body 10. A ring wall 12 extends downward from the inner side wall of the ring wall 11. A circular through hole 13 is formed in the center of the ring wall 12. The through hole 13 communicates with the cavity. The inner circumferential wall of the annular wall 12 is provided with a metal internal thread 14 for screwing into the external thread of the faucet inlet pipe. The upper top surface of the enclosure wall 11 is provided with a plurality of friction units 15 evenly distributed along the circumference. An opening is provided between adjacent friction units 15. The inside of the opening is provided with an elastic anti-slip claw 16 that protrudes from the upper top surface of the enclosure wall 11 and can be deformed. A clearance slot 17 is also provided at one corner of the upper top surface of the enclosure wall 11 for the passage of the inlet hose and / or pull-out pipe. The clearance slot 17 passes through the enclosure wall 11 and the annular wall 12 and communicates with the cavity.

[0030] Reference Figures 1 to 4In this embodiment, the friction unit 15 includes a plurality of wedge-shaped anti-slip teeth evenly distributed in a clockwise direction. Each wedge-shaped anti-slip tooth consists of an inclined surface and a stop surface perpendicular to it. After the nut is tightened, the inclined surface can increase the contact friction force and provide a stronger fixing effect. At the same time, the stop surface can effectively prevent the nut body 10 from rotating in the opposite direction when subjected to rotation or vibration, thereby playing the role of locking the nut body 10. This allows the nut body 10 to be more firmly fixed to the bottom wall of the basin, preventing the nut body 10 from loosening under the action of external torsional force, and improving the stability and reliability of the connection of the nut body 10. Furthermore, after the nut body 10 is tightened, the elastic anti-slip claw 16 will deform due to the external force, thereby generating a reverse clamping force. At the same time, it can further increase the friction with the bottom wall of the basin, further consolidate the locking effect of the nut body 10, and ensure that it can maintain a stable tightness during long-term use, preventing loosening. Moreover, since the nut body 10 of this solution is a rounded rectangle, workers can easily perform the locking operation without the aid of tools when locking the nut body 10, which is more efficient and has a better locking effect.

[0031] Reference Figures 1 to 5 In another embodiment, the friction unit 15 includes a plurality of arrow-shaped protrusions evenly distributed circumferentially, with the arrowheads of the plurality of arrow-shaped protrusions pointing in the same direction. This can effectively improve the friction effect and increase the friction force after the nut body 10 is locked. At the same time, the uniform distribution reduces local wear, thereby extending the service life.

[0032] Reference Figures 1 to 4 The length of the annular wall 12 is 1 / 4 or 2 / 5 of the length of the nut body 10. Two connecting protrusions 141 are provided on the upper and lower parts of the outer side of the metal internal thread 14. The two connecting protrusions 141 are embedded in the annular wall 12. With this arrangement, not only can the length of the metal internal thread 14 on the annular wall 12 be reduced, thus reducing the processing cost of the thread, but the connection stability between the metal internal thread 14 and the annular wall 12 can also be improved.

[0033] Reference Figures 1 to 7 The outer peripheral wall of the nut body 10 is provided with anti-slip units 18. In one embodiment, the anti-slip unit 18 is a plurality of anti-slip ridges and / or anti-slip grooves evenly distributed in the radial direction. In another embodiment, the anti-slip unit 18 is a plurality of anti-slip protrusions evenly distributed in the radial direction. With such a setting, the grip and friction of the nut body 10 can be effectively enhanced, the worker's control force when tightening the nut body 10 can be improved, and slippage or slippage can be avoided, thereby improving work efficiency.

[0034] Reference Figures 1 to 7The inner wall of the nut body 10 is provided with a plurality of axially extending reinforcing ribs 19. One end of the reinforcing rib 19 is connected to the ring wall 12, and the other end extends to the lower end of the nut body 10. This arrangement can improve the overall structural strength of the nut body 10, making it more robust and less prone to deformation when subjected to external forces.

[0035] It should be noted that this utility model can be applied not only to locking basin faucets, but also to pull-out faucets. Furthermore, the recessed groove 17 of this utility model can facilitate the passage of hot and cold water pipes and / or pull-out pipes, making it more versatile and easier to install.

[0036] 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.
