Description

Technical Field

[0001] This utility model relates to the field of faucet installation technology, specifically to a faucet installation anti-loosening nut structure. Background Technology

[0002] Currently, faucets are mainly installed and fixed to sinks or basins using a washer and nut, which are threaded onto the inlet pipe. Because faucets are used frequently, the repeated opening and closing of the handle causes the faucet mounting nut to loosen. Once loose, the faucet will rotate during use, and if completely loose, it will affect its operation. Since the inlet pipe needs to be installed after the faucet is finished, replacing the nut after a period of use requires removing the inlet pipe, which is inconvenient. Even after replacement, the nut is prone to loosening. Therefore, a reasonably designed anti-loosening nut structure for faucet installation needs further research. Utility Model Content

[0003] The purpose of this utility model is to provide a faucet installation anti-loosening nut structure. By combining two nut bodies to form a nut assembly, the installed product can play an anti-loosening role, solving the problem that it is very inconvenient to replace the nut by removing the water inlet pipe.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model relates to a faucet installation anti-loosening nut structure, including an anti-loosening nut and a reinforcing nut. The upper end surface of the anti-loosening nut has uniformly arranged knife-shaped anti-slip patterns in a ring shape. The anti-slip patterns extend from the outside to the inside with a height difference H1. The lower end of the anti-loosening nut is provided with a first handle position. The lower end of the anti-loosening nut has an outwardly convex conical surface. The center of the upper end of the anti-loosening nut and the center of the lower end have an eccentric displacement H4.

[0006] The lower end of the reinforcing nut is provided with a second handle position, and the upper end of the reinforcing nut has a reserved position for a hexagonal wrench. The upper end of the reinforcing nut is also provided with a concave conical surface. The diameter of the concave conical surface is adapted to the diameter of the lower end of the lock nut. The center of the lower end of the reinforcing nut and the center of the concave conical surface have an eccentric displacement H4. When the lock nut and the reinforcing nut are used together, the convex conical surface and the concave conical surface cooperate with each other.

[0007] Furthermore, the eccentric displacement H4 on the anti-loosening nut forms a 90° angle with the direction of the line connecting the first handle position, and the eccentric displacement H on the reinforcing nut forms a 90° angle with the direction of the line connecting the second handle position.

[0008] Furthermore, the second handle position of the reinforcing nut has a concave structure.

[0009] Furthermore, when the convex conical surface and the concave conical surface mate with each other, there is a gap between them.

[0010] Furthermore, the maximum height after the anti-loosening nut 1 and the reinforcing nut 2 are fitted together is 18mm to 25mm.

[0011] This utility model has the following beneficial effects:

[0012] This utility model combines two nuts to form a nut assembly. Once installed, the product can prevent loosening, thus solving the problem of loose nuts at its source. It is highly practical, low-cost, and can be widely applied.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-8 This utility model provides a technical solution: a faucet installation anti-loosening nut structure, including an anti-loosening nut 1 and a reinforcing nut 2. The upper end surface of the anti-loosening nut 1 has uniformly arranged knife-shaped anti-slip patterns 11 in an annular shape. The anti-slip patterns 11 extend from the outside to the inside with a height difference H1. When the nut is locked in place with the flat washer, because the flat washer is made of soft rubber, the deformation of the flat washer generates a gripping force, which plays a first-level anti-loosening effect. The lower end of the anti-loosening nut 1 is provided with two first handle positions 12. The lower end of the anti-loosening nut 1 has an outwardly convex conical surface 13. The center of the upper end of the anti-loosening nut 1 and the center of the lower end have an eccentric displacement H4.

[0025] The lower end of the reinforcing nut 2 is provided with a second handle position 21, and the upper end of the reinforcing nut 2 has a hexagonal wrench reserved position 22. The upper end of the reinforcing nut 2 is also provided with a concave conical surface 23. The diameter of the concave conical surface 23 is adapted to the diameter of the lower end of the anti-loosening nut 1. The center of the lower end of the reinforcing nut 2 and the center of the concave conical surface 23 have an eccentric displacement H4. When the anti-loosening nut 1 and the reinforcing nut 2 are used together, the convex conical surface 13 and the concave conical surface 23 cooperate with each other.

[0026] In this embodiment, as Figure 4 and Figure 6 As shown, the eccentric displacement H4 on the anti-loosening nut 1 forms a 90° angle with the line connecting the first handle position 12, and the eccentric displacement H4 on the reinforcing nut 2 forms a 90° angle with the line connecting the second handle position 21.

[0027] In this embodiment, as Figure 6 As shown, the second handle position 21 of the reinforcing nut 2 has a concave structure, which serves to prevent the hand from slipping during installation.

[0028] In this embodiment, as Figure 5 and Figure 8 As shown, when the convex conical surface 13 and the concave conical surface 23 are fitted together, there is a fitting gap between them.

[0029] In addition to facilitating the installation of both components, the clearance also needs to be considered so that when the thread center and the eccentric conical surface are locked together, an internal and external force will cause the thread and the conical surface to have a mutual pulling force, so that the reinforcing nut can play a second layer of anti-loosening effect.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the maximum height after the anti-loosening nut 1 and the reinforcing nut 2 are fitted together is 18mm to 25mm. Correspondingly, when the water inlet pipe is lengthened, this height is not limited.

[0031] In this embodiment, as Figure 2 As shown, there is an axial gap H2 between the lower end face of the anti-loosening nut 1 and the upper end face of the reinforcing nut 2, and a gap H3 between the first handle position 12 and the end face of the reinforcing nut 2.

[0032] H2 serves as the axial clearance when the anti-loosening nut 1 and the reinforcing nut 2 are combined. It is used to compensate for the axial deformation that may occur during the injection molding process, and to prevent the end faces of the two nuts from directly contacting or interfering after assembly, thus ensuring assembly accuracy and smooth operation.

[0033] H3 and H2 work together to adapt to the amount of injection molding deformation, ensuring the stability of the reinforcement nut's own structure and its fit with the anti-loosening nut. At the same time, they reserve reasonable space for the mutual tension of the subsequent conical surface fit, ensuring the realization of the second layer of anti-loosening function.

[0034] When using the above nuts:

[0035] When installing the faucet, slip the flat washer onto the inlet pipe foot, insert the anti-loosening nut 1, and manually tighten it to create a gripping force with the flat washer, achieving the first layer of anti-loosening effect. Then, tighten the reinforcing nut 2. When the anti-loosening nut 1 and the reinforcing nut 2 are tightened due to the cooperation between the thread center and the eccentric outwardly convex conical surface 13 and the concave conical surface 23, an internal and external force causes a mutual pulling force between the thread and the conical surface, so that the reinforcing nut 2 plays a second layer of anti-loosening effect.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
