Therefore, due to the accumulation of tolerances formed by manufacturing and assembly, it is often difficult to match the positions of threaded fasteners and nuts, or even if they can be matched, the stress after connection is too large. The nut structure that can adjust the position to compensate for the tolerance in the prior art is relatively complex, the assembly operation is complicated and difficult to implement in some small spaces.

[0003] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0005] The fastening structure of the utility model only includes a predetermined plate and a nut, and does not require other auxiliary devices, which simplifies the fastening structure that can compensate for tolerances, occupies less space, and has a wider range of applications. Only a nut mounting hole needs to be set on the predetermined plate, without other restrictions, and the structure is simple. The nut includes a main body and a connecting structure, and is fixed on the predetermined plate through the connecting structure. The connecting structure includes a first guide plate matching the first guide wall and a second guide plate matching the second guide wall, so that the connecting structure can slide in the nut mounting hole along the length direction of the first guide wall and the second guide wall. The connecting structure extends through the nut mounting hole, so that the connecting structure has a larger space to achieve connection with the plate. The connecting structure is accommodated in the nut mounting hole, so that the surface of the opening formed with the nut mounting hole on the predetermined plate can still remain flat, reducing the interference of the nut with other devices other than the predetermined plate, and further improving and broadening the use scenario of the fastening structure of the utility model. The first guide plate includes a first bending portion, the second guide plate includes a second bending portion, the predetermined plate has a first profile facing the main body, the first bending portion and the second bending portion are used to limit the nut from moving toward the side where the first profile is located to prevent the nut from falling off the predetermined plate.

[0006] In the preferred technical solution of the above fastening structure, during the process of installing the nut on the predetermined plate, the first bending portion and the second bending portion do not deform the predetermined plate. Through the above configuration, the nut of the utility model is different from some nuts in the prior art that deform the predetermined plate, including but not limited to pressure riveted nuts, etc., so that the material selection range of the predetermined plate is wider, further broadening the application scenario of the fastening structure of the utility model.

Through the above-mentioned arrangement, the main body also limits the movement of the nut in another direction, so that the nut is restricted in both directions perpendicular to the predetermined plate, ensuring the stability of the connection between the nut and the predetermined plate. The first bending portion has a first bending edge, the second bending portion has a second bending edge, the first bending edge and the second bending edge are parallel to each other, and the first bending edge and the second bending edge are parallel to the first surface or are formed on the first surface. Through the above-mentioned arrangement, along the length direction of the first bending edge or the second bending edge, the distance between the first bending edge and the second bending edge remains unchanged, and the distance between the first bending edge and the second bending edge and the first surface remains unchanged, so that when the connecting structure is placed in the nut mounting hole, it can slide in the hole to compensate for the tolerance.

Through the above-mentioned arrangement, the mutual abutment between the first guiding surface and the first fixing portion, the second guiding surface and the second fixing portion enables the nut to slide smoothly along the length direction of the first guide wall and the second guide wall. The first limiting surface and the second limiting surface are both inclined toward the side where the second profile of the predetermined plate is located, the first limiting surface abuts against at least a portion of the first bending portion, and the second limiting surface abuts against at least a portion of the second bending portion. Through the configuration of the first limiting surface and the second limiting surface, the first bending portion and the second bending portion can be more easily hidden in the nut mounting hole, while achieving the function of limiting the movement of the nut in a direction perpendicular to the predetermined plate, so as to reduce interference with other components other than the predetermined plate.

[0010] In the preferred technical solution of the above fastening structure, the first fixing portion abuts against the first guide wall, and the second fixing portion abuts against the second guide wall; the predetermined plate has a first profile away from the main body, and the first bending portion and the second bending portion both abut against the second profile. Through the above arrangement, the first bending portion and the second bending portion directly abut against the second profile, so that the connection between the nut and the predetermined plate is more stable.

[0011] In the preferred technical solution of the above fastening structure, the first bent edge and the second bent edge are both formed on the first surface; the first bent portion abuts against the first guide wall, and the second bent portion abuts against the second guide wall; the predetermined plate has a second profile away from the main body, and the first guide wall and the second guide wall are both inclined toward the side where the second profile is located.

[0013] The utility model adopts a nut with a main body, wherein the main body comprises a first surface and a second surface opposite to each other, a threaded hole is formed on the main body, and the threaded hole extends from the second surface toward the first surface, so that when the nut is installed in place, the threaded fastener can form a threaded connection with the threaded hole. The connection structure comprises a first guide plate and a second guide plate formed on the first surface, so that the guide structure of the nut for compensating the tolerance does not rely on the main body, and the assembly structure around the main body of the nut is simplified. The first guide plate comprises a first bending portion, the first bending portion has a first bending edge, the second guide plate comprises a second bending portion, the second bending portion has a second bending edge, the first bending edge and the second bending edge are parallel to each other, and the first bending edge and the second bending edge are both parallel to the first surface or are both formed on the first surface. Through the above configuration, in the length direction along the first bending edge or the second bending edge, the distance between the first bending edge and the second bending edge remains unchanged, and the distance between the first bending edge and the second bending edge and the first surface remains unchanged, so that when the connection structure of the nut is placed in a hole with matching parallel features, it can slide in the hole to compensate for the tolerance.

Through the above configuration, when the connecting structure of the nut is placed in a hole with matching parallel features, the two bending portions can be rotated in opposite directions to lock the nut in a direction perpendicular to the first surface, thereby limiting its movement in the direction perpendicular to the first surface.

[0014] In the preferred technical solution of the above nut, the first bent edge and the second bent edge are parallel to the first surface; the first guide plate further includes a first fixing portion extending between the first surface and the first bent edge, and the second guide plate further includes a second fixing portion extending between the first surface and the first bent edge.

[0015] In the preferred technical solution of the above nut, the first fixing portion and the second fixing portion are parallel to each other; or in the direction away from the first surface, the distance between the first fixing portion and the second fixing portion gradually decreases. The first fixing portion and the second fixing portion are parallel to each other, which ensures that the threaded fastener set in the threaded hole has sufficient passing space, and can also minimize the space occupied by the connection structure.

[0016] In the preferred technical solution of the above-mentioned nut, the first fixing portion has a first side and a second side that are opposite and intersecting with the first surface, and the second fixing portion has a third side and a fourth side that are opposite and intersecting with the first surface; the connection structure also includes a first connecting wall and a second connecting wall formed on the first surface, the first connecting wall extends from the first side to the third side, and the second connecting wall extends from the second side to the fourth side, and the first connecting wall, the first fixing portion, the second connecting wall and the second fixing portion are circumferentially surrounding the outer side of the threaded hole.

The first connecting wall, the first fixing portion, the second connecting wall and the second fixing portion are circumferentially surrounding the outer side of the threaded hole, reducing the space occupied by the connection structure.

[0017] In the preferred technical solution of the above nut, the first connecting wall and the second connecting wall are both arched in a direction away from the center line of the threaded hole. Through the above arrangement, the outwardly arched connecting portion can play a guiding role when the nut slides along the length direction of the first bent edge or the second bent edge to prevent jamming.

[0018] In the preferred technical solution of the above nut, in the direction away from the center line, the height of the first connecting wall and the second connecting wall relative to the first surface gradually decreases. Through the above arrangement, when the nut is installed in a suitable hole, the first connecting wall and the second connecting wall located on both sides of the connecting structure and having a gradually decreasing height can play a guiding role, thereby improving the installation efficiency.

[0032] Figure 1 Schematic diagram of the structure of the embodiment of the nut of the utility model. Figure 1 As shown, the nut 100 of the present invention includes a main body 10 and a connecting structure 20. The main body 10 includes a first surface 11 and a second surface 12 opposite to each other. A threaded hole 13 is formed on the main body 10 for accommodating a threaded fastener such as a screw or a stud. In one or more embodiments, the threaded hole 13 extends from the second surface 12 toward the first surface 11 to be flush with the first surface 11. Alternatively, the threaded hole 13 may also extend beyond the plane where the first surface 11 is located or extend to a position between the first surface 11 and the second surface 12 according to actual conditions, for example, at Figure 1 In the embodiment, a filling structure 14 protruding from the first surface 11 is provided inside the connection structure 20 , and the threaded hole 13 extends from the second surface 12 beyond the plane where the first surface 11 is located to penetrate the filling structure 14 .

[0033] Figure 2 It is a front view of an embodiment of the nut of the utility model; Figure 3 It is a side view of an embodiment of the nut of the utility model; Figure 4 1 is a bottom view of an embodiment of the nut of the utility model. Figure 2 and Figure 3As shown, the connection structure 20 includes a first guide plate 21 and a second guide plate 22. In one or more embodiments, the first guide plate 21 includes a first fixing portion 211 and a first bending portion 212. The first fixing portion 211 is formed on the first surface 11, and the first bending portion 212 is formed on a side of the first fixing portion 211 opposite to the first surface 11. The second guide plate 22 includes a second fixing portion 221 and a second bending portion 222. The second fixing portion 221 is formed on the first surface 11, and the second bending portion 222 is formed on a side of the second fixing portion 221 opposite to the first surface 11. In an alternative embodiment, the first fixing portion 211 and the second fixing portion 221 may be eliminated, so that the first bending portion 212 and the second bending portion 222 are directly formed on the first surface 11.

[0034] Continue reading Figure 2 and Figure 3 In the embodiment with the first fixing portion 211 and the second fixing portion 221, in the initial position, the first fixing portion 211 and the first bending portion 212 form a flat plate-like component for easy manufacturing. Similarly, the second fixing portion 221 and the second bending portion 222 also form a flat plate-like component. In the process of switching to the working position, the first bending portion 212 rotates relative to the first fixing portion 211 and displays the first bending edge 213 of the first bending portion 212 (at Figure 5 Similarly, in the working position, the second bending portion 222 rotates relative to the second fixing portion 221, and the second bending edge 223 of the second bending portion 222 is displayed (in Figure 5 ). The first bending portion 212 and the second bending portion 222 rotate in opposite directions, so as to expand the area of ​​the connection structure 20 in the direction perpendicular to the first surface 11, and can be used to limit the movement of the nut 100 in the direction perpendicular to the first surface 11. The first bending edge 213 and the second bending edge 223 are parallel to each other, and the second bending edge 223 and the second bending edge 223 are both parallel to the first surface 11, so as to facilitate the translation of the nut 100. The first fixing portion 211 extends between the first surface 11 and the first bending portion 212, and the second fixing portion 221 extends between the first surface 11 and the second bending edge 223.

[0035] In one or more embodiments, the first fixing portion 211 and the second fixing portion 221 are both perpendicular to the first surface 11, and because the first bending edge 213 and the second bending edge 223 are parallel to each other, the first fixing portion 211 and the second fixing portion 221 are parallel to each other. Alternatively, the first fixing portion 211 and the second fixing portion 221 may also be configured to form other suitable predetermined angles, for example, in a direction away from the first surface 11, the distance between the first fixing portion 211 and the second fixing portion 221 gradually decreases, or in a direction away from the first surface 11, the distance between the first fixing portion 211 and the second fixing portion 221 gradually increases.

[0036] Continue reading Figure 2 and Figure 4 In one or more embodiments, a first connecting wall 23 and a second connecting wall 24 are provided between the first fixing portion 211 and the second fixing portion 221. Figure 2 and Figure 4 As shown, the first fixing portion 211 has a first side 2111 and a second side 2112 that are opposite and intersect with the first surface 11. The second fixing portion 221 has a third side 2211 and a fourth side 2212 that are opposite and intersect with the first surface 11. The first connecting wall 23 and the second connecting wall 24 are both formed on the first surface 11, and the first connecting wall 23 extends from the first side 2111 to the third side 2211, and the second connecting wall 24 extends from the second side 2112 to the fourth side 2212. The first connecting wall 23, the first fixing portion 211, the second connecting wall 24 and the second fixing portion 221 are sequentially connected and form a closed loop, surrounding the outer side of the threaded hole 13. Alternatively, the first connecting wall 23 and the second connecting wall 24 can also be eliminated.

[0037] Continue reading Figure 4 In one or more embodiments, the first connecting wall 23 and the second connecting wall 24 are both arched in a direction away from the axis of the threaded hole 13, and are substantially C-shaped. Alternatively, the first connecting wall 23 and the second connecting wall 24 may also be configured into other suitable shapes according to actual conditions.

[0038] Continue reading Figure 2 In one or more embodiments, the heights of the first connecting wall 23 and the second connecting wall 24 relative to the first surface 11 gradually decrease in a direction away from the axis of the threaded hole 13. Alternatively, the first connecting wall 23 and the second connecting wall 24 may also be configured to other suitable heights.

[0039] In order to solve the problem of the complexity of the nut assembly structure that can compensate for tolerance in the prior art, the utility model also provides a fastening structure. The fastening structure 300 of the utility model includes: a predetermined plate 30, the predetermined plate 30 is formed with a nut mounting hole 33, the nut mounting hole 33 includes a first guide wall 331 and a second guide wall 332 opposite to each other; and a nut 100, the nut 100 forms a sliding connection with the predetermined plate 30, the nut 100 includes a main body 10 and a connecting structure 20 formed on the main body 10, the connecting structure 20 is accommodated in the nut mounting hole 33 or extends through the nut mounting hole 33, the connecting structure 20 includes a first guide plate 21 and a second guide plate 22 opposite to each other, the first guide plate 21 and the second guide plate 22 opposite to each other, and the first guide plate 21 and the second guide plate 22 opposite to each other. The guide plate 21 matches the first guide wall 331, and the second guide wall 332 matches the second guide plate 22, so that the connecting structure 20 can slide in the nut mounting hole 33 along the length direction of the first guide wall 331 and the second guide wall 332, wherein the first guide plate 21 includes a first bending portion 212, and the second guide plate 22 includes a second bending portion 222, and the predetermined plate 30 has a first profile 31 facing the main body 10, and the first bending portion 212 and the second bending portion 222 are used to limit the movement of the nut 100 toward the side where the first profile 31 is located.

[0040] Figure 5 It is a cross-sectional schematic diagram of an embodiment of the fastening structure of the utility model; Figure 6 1 is a schematic diagram of the structure of an embodiment of a predetermined plate 30 of a fastening structure of the utility model. The fastening structure 300 of the utility model comprises a predetermined plate 30 and a nut 100 slidably connected to the predetermined plate 30.

[0041] In one or more embodiments, a nut mounting hole 33 is formed on the predetermined plate 30. The connection structure 20 on the nut 100 can extend through the nut mounting hole 33 or be accommodated in the nut mounting hole 33. In the process of installing the nut 100 on the predetermined plate 30, the first bending portion 212 and the second bending portion 222 do not deform the predetermined plate 30. That is, when the first bending portion 212 and the second bending portion 222 are switched from the initial position to the working position, only the connection structure 20 can be deformed, and the predetermined plate 30 does not deform. Therefore, the predetermined plate 30 can be any suitable plate, such as a brittle glass plate, a metal plate or a plastic plate with weak ductility. Since the nut 100 of the utility model does not need to deform the plate to ensure the connection strength like the pressure rivet nut and the expansion rivet nut in the prior art, the fastening structure 300 of the utility model can use any suitable plate, and it is only necessary to process a suitable nut mounting hole on the predetermined plate 30.

[0042] Continue reading Figure 5 and Figure 6In one or more embodiments, the predetermined plate 30 has a first profile 31 and a second profile 32. The first profile 31 faces the body 10 and abuts against the first surface 11 to limit the movement of the nut 100 toward the side where the second profile 32 of the predetermined plate 30 is located. Figure 5 The orientation shown, i.e., limits the downward movement of the nut 100. Alternatively, a gasket or other component may also be provided between the first profile 31 and the first surface 11. In one or more embodiments, the nut mounting hole 33 extends from the first profile 31 to the second profile 32, penetrating the predetermined plate 30. The nut mounting hole 33 includes a first guide wall 331 and a second guide wall 332 relative to each other. The first guide wall 331 and the second guide wall 332 both extend between the first profile 31 and the second profile 32. The opening size of the nut mounting hole 33 is larger than the outer size of the connecting structure 20 of the nut 100. Specifically, the length of the first guide wall 331 and the second guide wall 332 is larger than the length of the first guide plate 21 and the second guide plate 22, so that the connecting structure 20 can slide in the nut mounting hole 33 along the length direction of the first guide wall 331 and the second guide wall 332 to compensate for errors caused by manufacturing or assembly. Based on Figure 6 In the shown orientation, the length direction of the first guide wall 331 and the second guide wall 332 is the left-right direction.

[0043] The first guide wall 331 matches the first guide plate 21, and the second guide wall 332 matches the second guide plate 22, so that the nut 100 can freely reciprocate along the length direction of the first guide plate 21 after being installed in the nut installation hole 33. Figure 5 As shown, in one or more embodiments, the first guide wall 331 includes a first guide surface 3311 and a first limiting surface 3312, and the second guide wall 332 includes a second guide surface 3321 and a second limiting surface 3322. The first guide plate 21 includes a first fixing portion 211 and a first bending portion 212, and the second guide plate 22 includes a second fixing portion 221 and a second bending portion 222. The first limiting surface 3312 and the second limiting surface 3322 are both inclined toward the side where the second profile 32 of the predetermined plate 30 is located, based on Figure 5 In the orientation shown, the first limit surface 3312 and the second limit surface 3322 are both tilted downward. The first bending portion 212 and the second bending portion 222 are both in the working position, and at least a portion of the first bending portion 212 abuts against the first limit surface 3312 and is accommodated in the nut mounting hole 33, and at least a portion of the second bending portion 222 abuts against the first limit surface 3312 and is accommodated in the nut mounting hole 33, so that the first bending portion 212 and the second bending portion 222 do not exceed the nut mounting hole 33, and the second profile 32 is kept flat. Based on Figure 5In the orientation shown, the first bending portion 212 and the second bending portion 222 are used to limit the movement of the nut toward the side where the first profile of the predetermined plate is located, that is, to limit the upward movement of the nut 100 after it is installed on the predetermined plate 30. In addition, when the threaded fastener needs to be installed on the nut 100, when the threaded fastener is rotated into the threaded hole 13, due to the limitation of the first guide wall 331 and the second guide wall 332, the nut 100 will not rotate in the same direction as the threaded fastener due to friction. The nut 100 in the prior art achieves the effect of preventing the nut 100 from rotating by embedding part of the structure of the nut 100 into the plate. Therefore, the nut 100 and the fastening structure 300 of the utility model have a wider range of application scenarios.

[0044] Alternatively, the first bent portion 212 and / or the second bent portion 222 may also be configured to extend beyond the nut mounting hole 33 to ensure connection reliability. In one or more embodiments, the first guide surface 3311 and the second guide surface 3321 are parallel to each other. Alternatively, the first guide surface 3311 and the second guide surface 3321 may also be configured to form a predetermined angle to match the angle formed between the first fixing portion 211 and the second fixing portion 221.

[0045] In an alternative embodiment, the first limiting surface 3312 and the second limiting surface 3322 may also be eliminated. The first guide plate 21 includes a first fixing portion 211 and a first bending portion 212, and the second guide plate 22 includes a second fixing portion 221 and a second bending portion 222. The first fixing portion 211 abuts against the first guide wall 331, and the second fixing portion 221 abuts against the second guide wall 332. The first bending portion 212 extends beyond the nut mounting hole 33, and in the working position, at least a portion of the first bending portion 212 abuts against the second profile 32. Similarly, the second bending portion 222 extends beyond the nut mounting hole 33, and in the working position, at least a portion of the second bending portion 222 abuts against the second profile 32, thereby limiting the movement of the nut 100 toward the side where the first profile 31 is located after the nut 100 is installed on the predetermined plate 30.

[0046] In an alternative embodiment, the first fixing portion 211 and the second fixing portion 221 may be omitted. The first bending edge 213 and the second bending edge 223 are both formed on the first surface 11. The first guide wall 331 and the second guide wall 332 are both configured to be inclined toward the side where the second profile 32 of the predetermined plate 30 is located, so that when the first bending portion 212 and the second bending portion 222 are both located in the working position, the first bending portion 212 abuts against the first guide wall 331, and the second bending portion 222 abuts against the second guide wall 332, thereby limiting the movement of the nut 100 toward the side where the first profile 31 is located after the nut 100 is installed on the predetermined plate 30.
