Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to a nut-toothed ring bolt assembly for use in self-locking joints. Background Technology

[0002] In aviation hydraulic piping systems, pipelines are connected and sealed via threaded connections. After tightening, the traditional method of thread locking involves inserting a fuse through the threaded hole of the connection and screwing it in a specific manner to prevent loosening. The drawbacks of this fuse structure are its complex installation, lack of maintainability, and poor reassembly capability. Therefore, the assembly of the self-locking nut has been optimized. By stamping the self-locking nut to achieve its self-locking function, product reliability is improved, and the manufacturing process is simplified. Utility Model Content

[0003] To address the aforementioned technical problems, a nut-toothed ring bolt assembly for self-locking joints is provided. The technical means employed in this invention are as follows:

[0004] A nut-toothed ring bolt assembly for use in a self-locking connector includes: a bolt with a toothed ring and a self-locking nut. The self-locking nut has a through hole inside and an internal thread inside the through hole. One end of the self-locking nut has multiple stamped parts formed by stamping. The stamped parts are asymmetrical protrusions facing the inside of the self-locking nut.

[0005] The outer wall of the toothed bolt is provided with an external thread and a toothed ring portion. The external thread is connected to the internal thread of the self-locking nut. The self-locking nut and the toothed bolt are assembled by tightening the thread. The toothed ring portion is composed of multiple teeth evenly distributed circumferentially along the outer wall of the toothed bolt. The multiple stamped parts are connected to the toothed ring portion to realize the self-locking function.

[0006] Furthermore, the stamping part is composed of a continuously connected arc-shaped curved surface and a straight surface, wherein the spiraling direction is the arc-shaped curved surface and the spiraling out direction is the straight surface.

[0007] Furthermore, the plurality of stamping parts are evenly distributed along the circumferential direction.

[0008] Furthermore, the self-locking nut includes a nut section and a cylindrical section connected together, and the plurality of stamped parts are disposed on the cylindrical section at one end away from the nut section.

[0009] Furthermore, the nut segment is a hexagonal nut structure.

[0010] Furthermore, the toothed bolt includes a threaded section, a toothed ring section, a bolt section, and a cylindrical section connected in sequence, with the external thread disposed on the outer wall of the threaded section and the toothed ring portion disposed on the outer wall of the toothed ring section.

[0011] Furthermore, the bolt segment is a hexagonal bolt structure.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The nut-toothed ring bolt assembly for self-locking joints provided by this utility model optimizes the assembly of the self-locking nut. By stamping the self-locking nut to achieve the self-locking function, the reliability of the product is improved and the processing difficulty of the product is reduced.

[0014] 2. The nut-toothed ring bolt assembly for self-locking joints provided by this utility model has an asymmetrical structure in the stamping part of the self-locking nut, that is, the screwing-in direction is an arc curve and the screwing-out direction is a straight line. Therefore, the torque that needs to be overcome when screwing out is greater than the torque that needs to be overcome when screwing in, thereby achieving the anti-loosening function and minimizing the impact on the assembly torque, thus achieving the self-locking function.

[0015] Based on the above reasons, this utility model can be widely promoted in fields such as thread loosening prevention. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This utility model provides an assembly design for a self-locking sealing structure, which utilizes the stamped portion of the nut to ensure the self-locking function.

[0024] refer to Figure 1 An example of a bolt-self-locking nut assembly design with a toothed ring is given. This utility model consists of a bolt 100 with a toothed ring and a self-locking nut 110.

[0025] The self-locking nut 110 includes a nut section and a cylindrical section connected together, with the nut section having a hexagonal nut structure. The self-locking nut 110 has a through hole with internal threads. A stamping process is performed below the threaded end of the self-locking nut 110 to form a stamped portion 120. Specifically, a stamped portion 120 is formed by stamping at the end of the cylindrical section away from the nut section. In this embodiment, four stamped portions 120 are provided, evenly distributed along the circumference; each stamped portion 120 is a raised structure facing inwards from the cylindrical section. The stamped portion 120 has an asymmetrical structure, composed of continuously connected arcuate curved surfaces and straight surfaces, with the screw-in direction being the arcuate curved surface and the screw-out direction being the straight surface.

[0026] The toothed bolt 100 comprises a threaded section, a toothed ring section, a bolt section, and a cylindrical section connected in sequence. The bolt section is a hexagonal bolt. The outer wall of the threaded section has external threads, which engage with the internal threads of the self-locking nut 110. The outer wall of the toothed ring section has a toothed ring portion 130, which consists of multiple teeth evenly distributed along the circumference of the outer wall of the toothed ring section. The stamped part 120 engages with the toothed ring portion 130 to achieve a self-locking function.

[0027] Connect the toothed bolt 100 to the self-locking nut 110, and assemble the self-locking nut 110 and the toothed bolt 100 by tightening the threads.

[0028] First, assemble the toothed bolt 100 with the self-locking nut 110. During the screwing process, the stamped part 120 of the self-locking nut 110 contacts the toothed part 130 of the toothed bolt 100. Since the stamped part 120 of the self-locking nut 110 has an asymmetrical structure, that is, the screwing direction is an arc curve and the screwing out direction is a straight line, the torque that needs to be overcome when screwing out is greater than the torque that needs to be overcome when screwing in. This achieves the anti-loosening function and minimizes the impact on the assembly torque, thus achieving the self-locking function.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
