The connecting part is adapted to allow the position of the threaded body relative to the fixing part to be adjustable, so that the threaded hole and bolt hole are aligned. This adjustable position of the threaded body relative to the fixing part greatly facilitates the alignment of the threaded hole and bolt hole. Although it is an integral structure, the connecting part gives the threaded body an adjustable position, allowing the entire nut plate structure to adapt to different installation environments and requirements while maintaining a certain strength. When faced with limited installation space or inaccurate installation positions, the installation requirements can be met by adjusting the position of the bolted main body, without being limited by the fixed structure. This adjustability, combined with the integrated structure, ensures both the stability of the nut plate structure and improves its adaptability.

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0040] This application provides a nut plate structure; please refer to [link / reference]. Figures 1 to 3 , Figure 1 This is one of the structural schematic diagrams of the nut plate structure provided in the exemplary embodiments of this disclosure. Figure 2 yes Figure 1 The top view of the nut plate structure shown is shown. Figure 3 yes Figure 1 The diagram shows a front view of the nut plate structure. The nut plate structure 10 includes a screw-in body 11, a fixing part 12, and a connecting part.

[0041] The threaded body 11 is provided with a threaded hole 111, and the threaded body 11 is used to be located on one side of the part to be connected, which has a bolt hole 21.

[0042] It should be noted that the shape of the screw-on body 11 can be set as needed, and this application does not limit it. In addition, the type of the parts to be connected is also not limited.

[0043] The fixing part 12 is used to fix it to the part to be connected.

[0044] It should be noted that the method of fixing the fixing part 12 to the part to be connected can be selected as needed. For example, in some embodiments, the fixing part 12 and the part to be connected can be fixed by welding. In other embodiments, the fixing part 12 and the part to be connected can be fixed by adhesive. In other embodiments, the fixing part 12 and the part to be connected can be fixed by snap-fit ​​structure, etc. Of course, the fixing part 12 and the part to be connected can be fixed by threaded structure. Specifically, this application does not limit this.

[0045] In the nut plate structure 10 of this application embodiment, the fixing part 12, the threaded body 11, and the connecting part are integrally formed. This integral forming of the fixing part 12, the threaded body 11, and the connecting part reduces the number of parts and assembly steps, alleviating the workload of the assembler. During installation, the connection between the nut plate structure 10 and the part to be connected is achieved simply by fixing the fixing part 12 to the part to be connected. Compared to installing multiple separate components, this greatly simplifies the assembly process and improves assembly efficiency. Furthermore, the integral forming of the fixing part 12, the threaded body 11, and the connecting part reduces the risk of structural damage caused by loosening or separation between these components. The connecting part is adapted to allow the position of the threaded body 11 relative to the fixing part 12 to be adjustable, so that the threaded hole 111 and the bolt hole 21 are aligned. This adjustable position of the threaded body 11 relative to the fixing part 12 greatly facilitates the alignment of the threaded hole 111 and the bolt hole 21. Despite being a single-piece structure, the connecting part gives the bolted main body 11 an adjustable position, allowing the entire nut plate structure 10 to adapt to different installation environments and requirements while maintaining a certain level of strength. When encountering situations with limited installation space or inaccurate installation positions, the position of the bolted main body 11 can be adjusted to meet installation needs without being limited by the structure's fixed nature. This adjustability, combined with the single-piece structure, ensures both the stability and adaptability of the nut plate structure 10.

[0046] Reference Figure 2 and Figure 3In some embodiments, the fixing part 12 includes multiple fixing plates 121, which are arranged circumferentially around the threaded hole 111. This allows the nut plate structure 10 to be fixedly connected to the component to be connected from multiple directions, creating a multi-point fixing effect. This multi-point fixing method greatly increases the connection strength between the nut plate structure 10 and the component to be connected, effectively preventing loosening or displacement of the nut plate structure 10 during use. At least one fixing plate 121 is radially spaced from the threaded body 11 along the threaded hole 111, thus providing adjustment space for adjusting the position of the nut body. The connecting part includes multiple connecting arms 131, and each fixing plate 121 is connected to the threaded body 11 through a connecting arm 131. Thus, the multiple connecting arms 131 and the multiple fixing plates 121 together constitute a spatial frame structure. This frame structure has high strength and rigidity, effectively resisting deformation. When bearing load, the connecting arms 131 and the fixing plates 121 can work together to distribute and transmit force, avoiding excessive local stress that could damage the nut plate structure 10. The circumferential and partially radial spacing of the fixing plates 121 allows the entire structure to better adapt to different installation spaces during installation. If other components or obstacles exist around the installation location, this spaced-out structure allows for flexible adjustment of the installation angle and position, avoiding interference with other components. The presence of the connecting arms 131 also provides installation flexibility. During installation, the relative position or orientation of the connecting arms 131 can be adjusted to facilitate alignment of the screw-on body 11 with the corresponding threaded holes 111 or bolt holes 21, reducing installation difficulty and improving assembly efficiency.

[0047] It should be noted that "multiple" in "multiple fixing plates 121" and "multiple connecting arms 131" refers to two or more. Of course, in other embodiments, the specific number referred to as "multiple" can be selected as needed, and this application does not limit this. The shape of the fixing part 12 can be set as needed. For example, in one embodiment, the fixing plate 121 can be set as a square plate, a triangular plate, or an elliptical plate, etc. Specifically, this application does not limit the specific shape of the fixing plate 121, as long as the fixing plate 121 meets the space requirements for spot welding, so as to facilitate the fixing of the nut plate structure 10 and the part to be connected.

[0048] In some embodiments, the connecting arm 131 is directly connected to the edge of the fixing plate 121. This increases the length of the connecting arm 131, thereby reducing its rigidity and facilitating the adjustment of the position of the screw-in body 11. Furthermore, the connection between the screw-in body 11 and the connecting arm 131 uses a large arc for a smooth transition. Similarly, the connection between the connecting arm 131 and the fixing plate 121 can also use a large arc for a smooth transition. Specifically, this application does not limit this aspect.

[0049] Continue to refer to Figure 2 and Figure 3 In some embodiments, the screw-in body 11 has two first side surfaces 112 arranged radially opposite to each other along the threaded hole 111, and each first side surface 112 is correspondingly provided with a fixing plate 121. Thus, the two first side surfaces 112 respectively correspond to the fixing plate 121, effectively fixing the nut plate structure 10 from two opposite directions. This fixing method increases the stability of the connection between the nut plate structure 10 and the component to be connected. Furthermore, when an external load is applied to the screw-in body 11, the stress is evenly transmitted to the component to be connected through the fixing plates 121 on both sides. This uniform stress distribution avoids stress concentration in a localized area of ​​the component to be connected, reducing the risk of material damage due to excessive stress and extending the service life of the component to be connected.

[0050] Reference Figure 2 In some embodiments, the screw-in body 11 has a diagonal, and the fixing plate 121 corresponding to the first side 112 is located on the diagonal. In this way, the length of the connecting arm 131 can be increased to a certain extent, thereby reducing the rigidity of the connecting arm 131 and making it easier for the screw-in body 11 to be adjusted in position as needed.

[0051] It should be noted that the position of the fixing plate 121 relative to the first side surface 112 can be selected as needed. For example, referring to... Figure 5 , Figure 5 This is a second schematic diagram of the nut plate structure provided in an exemplary embodiment of this disclosure. In some embodiments, the fixing plate 121 corresponding to the first side 112 may also be directly opposite the first side 112. In still other embodiments, the fixing plate 121 corresponding to the first side 112 may also be located on both sides of the diagonal of the screw-on body 11. Specifically, this application does not limit this.

[0052] In some embodiments, the diagonal of the screw-in body 11 intersects the axis of the threaded hole 111, thus making the nut plate structure 10 compact. This allows the nut plate structure 10 to be installed even in certain locations within the installation space, improving its applicability.

[0053] Reference Figure 2 and Figure 5 In some embodiments, each connecting arm 131 has a first connecting end 131a and a second connecting end 131b. The first connecting end 131a is connected to one of the two first side faces 112, and the second connecting end 131b is connected to a fixing plate 121 corresponding to the other of the two first side faces 112. This increases the length of the connecting arm 131, thereby reducing its rigidity, facilitating adjustment of the position of the screw-in body 11 as needed, and simplifying operation.

[0054] Reference Figure 2 and Figure 5 In some embodiments, each connecting arm 131 includes a first connecting segment 1311 connected to the first side surface 112, the first connecting segment 1311 extending away from the first side surface 112. This increases the length of the connecting arm 131, thereby reducing its rigidity, facilitating adjustment of the position of the threaded body 11 as needed, and simplifying operation. Furthermore, the first connecting segments 1311 and corresponding fixing plates 121 are spaced apart along the radial direction of the threaded hole 111. This spacing between the first connecting segments 1311 and the fixing plates 121 provides deformation space for the first connecting segments 1311, facilitating adjustment of the shape of the connecting portion to adjust the position of the threaded body 11.

[0055] Reference Figure 2 and Figure 5 In some embodiments, the fixing plate 121 has a connecting end face 1211 facing away from the first connecting segment 1311, and the second connecting end 131b is connected to the connecting end face 1211. This increases the length of the connecting arm 131 in the direction between the fixing plate 121 and the first connecting segment 1311, thereby reducing the rigidity of the connecting arm 131, facilitating adjustment of the position of the screw-on body 11 as needed, and simplifying operation.

[0056] Reference Figure 2 and Figure 5 In some embodiments, the fixing plate 121 has a second side 1212 disposed opposite to the first side 112, and the first connecting end 131a is adjacent to or connected to the second side 1212. In this way, the length of the connecting arm 131 in the spaced direction between the two first sides 112 is increased, thereby reducing the stiffness of the connecting arm 131, facilitating the adjustment of the position of the screw-on body 11 as needed, and simplifying the operation.

[0057] Reference Figure 2 and Figure 5 In some embodiments, the connecting arm 131 further includes a second connecting segment 1312. The two ends of the second connecting segment 1312 are respectively connected to the first connecting segment 1311 and the fixing plate 121. Along the radial direction of the threaded hole 111, the second connecting segment 1312 is spaced apart from the threaded body 11. Thus, the spacing between the second connecting segment 1312 and the threaded body 11 provides clearance for adjusting the position of the threaded body 11, ensuring that the position of the threaded body 11 can be adjusted as needed. Furthermore, the spacing between the second connecting segment 1312 and the threaded body 11 also facilitates adjusting the shape of the second connecting segment 1312 as needed, thereby enabling position adjustment of the threaded body 11.

[0058] It should be noted that in some embodiments, the first connecting segment 1311 may be entirely linear, and the second connecting segment 1312 may be partially linear. In other embodiments, both the first connecting segment 1311 and the second connecting segment 1312 may be curved. Of course, in other embodiments, the first connecting segment 1311 may be partially linear, and the second connecting segment 1312 may be linear. Specifically, this application does not limit this. In addition, the second connecting segment 1312 is curved radially toward or away from the threaded body 11 along the threaded hole 111. This can further increase the length of the connecting arm 131, thereby reducing the length of the connecting arm 131 and facilitating adjustment of the position of the threaded body 11 as needed.

[0059] Reference Figure 2 , Figure 4 as well as Figure 5 , Figure 4 yes Figure 1 The diagram shows a side view of the nut plate structure. In some embodiments, the first connecting end 131a is located at or near the center of the first side surface 112. This increases the length of the connecting arm 131 in the radial direction intersecting the normal of the first side surface 112, thereby reducing the stiffness of the connecting arm 131, facilitating adjustment of the position of the screw-on body 11 as needed, and simplifying operation.

[0060] Reference Figure 1 , Figure 3 as well as Figure 4 In some embodiments, the screw-in body 11 includes mounting plates 113 and 114. Mounting plate 113 has a first mounting end face 1131 and a second mounting end face 1132 that are axially opposite to each other along the threaded hole 111. The first mounting end face 1131 is opposite to the part to be connected. Mounting plate 113 has a through hole 1133. 114 is connected to the second mounting end face 1132 and has a threaded hole 111. The through hole 1133 and the threaded hole 111 are coaxially aligned and connected. Thus, mounting plate 113 serves as an intermediate transition structure, with its first mounting end face 1131 opposite to the part to be connected, increasing the contact area between the screw-in body 11 and the part to be connected. When the bolt passes through the through hole 1133 and engages with the threaded hole 111 of 114, the larger contact area can disperse the stress borne by the connection, reducing local stress concentration and making the connection more secure and reliable, effectively reducing the risk of loosening due to excessive stress. The through hole 1133 and the threaded hole 111 are coaxially arranged and connected, providing precise guidance for bolt installation. During installation, the bolt can smoothly pass through the through hole 1133 and screw into the threaded hole 111, ensuring accurate fit between the bolt and 114 and reducing connection quality problems caused by installation deviations.

[0061] It should be noted that the connection method between 114 and mounting plate 113 is flexible, and different connection methods can be selected according to actual needs, such as welding, integral molding, or adhesive bonding. Specifically, this application does not limit this.

[0062] Reference Figure 2 and Figure 5 In some embodiments, the fixing part 12 is spaced apart from the threaded body 11 along the radial direction of the threaded body 11. The threaded body 11 is adapted to rotate about the axis of the threaded hole 111, thus facilitating the tightening operation between the threaded body 11 and the bolt. Furthermore, during the rotation of the threaded body 11, the circumference of the threaded body 11 is adapted to abut against the circumference of the fixing part 12. This reduces and limits the rotation angle of the threaded body 11. When the threaded body 11 rotates to abut against the circumference of the fixing part 12, the fixing part 12 will stop the rotation of the threaded body 11, thereby facilitating the tightening of the bolt into the threaded hole 111.

[0063] It should be noted that, in order to achieve the condition that the periphery of the screw-connecting body 11 is suitable for abutting against the periphery of the fixing part 12 during the rotation of the screw-connecting body 11, the boundary of the fixing part 12 is within the rotation radius of the screw-connecting body 11. In this way, the purpose can be to limit the rotation angle of the screw-connecting body 11 during the tightening of the bolt and the screw-connecting body 11.

[0064] Reference Figure 3 and Figure 4 In some embodiments, the connecting arm 131 includes a first arm segment 1313 and a second arm segment 1314. One end of the first arm segment 1313 is connected to the fixing plate 121, and the other end of the connecting arm 131 is disposed axially away from the fixing plate 121 along the threaded hole 111. The other end of the first arm segment 1313 is connected to the second arm segment 1314, and the other end of the second arm segment 1314 is connected to the screw-in body 11. This design results in a longer connecting arm 131, reducing its rigidity and facilitating adjustment of the position of the screw-in body 11 as needed, simplifying operation. Furthermore, this design ensures that the connecting arm 131 does not contact the part to be connected during deformation, helping to avoid structural noise.

[0065] In some embodiments, at least one of the first arm segment 1313 and the second arm segment 1314 is bent, which makes the length of the connecting arm 131 longer, thereby reducing the rigidity of the connecting arm 131 and making it easier to adjust the position of the screw body 11 as needed, and simplifying the operation.

[0066] Reference Figure 3 and Figure 4In some embodiments, both the first arm segment 1313 and the second arm segment 1314 are curved. The first arm segment 1313 is wavy and the second arm segment 1314 is spirally curved. This greatly increases the length of the connecting arm 131, reduces the stiffness of the connecting arm 131, and ensures that the connecting arm 131 does not come into contact with the part to be connected during deformation, which helps to avoid abnormal noise from the structure.
