[0038] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 5A nut 100 according to an embodiment of the first aspect of the present invention is described.

[0039] like Figure 1-Figure 4 As shown, the nut 100 according to the first embodiment of the utility model includes a body 1.

[0040] Specifically, a matching groove 11 is formed on one side of the body 1, and a plurality of ribs 111 are arranged on the side wall of the matching groove 11. In the description of the present utility model, "multiple" means two or more. Each rib 111 extends along the circumference of the matching groove 11, and the plurality of ribs 111 are arranged at intervals along the axial direction of the body 1. For example, Figure 1-Figure 4 In the example, the matching groove 11 is formed on the lower side of the body 1, and the convex ribs 111 may be provided with five or seven. The arrangement of the convex ribs 111 may include the following situations: first, the convex ribs 111 extend along the circumference of the matching groove 11 in a closed shape (such as Figure 1 and Figure 2 As shown, that is, the shape of the convex rib 111 is circular). Second, the convex rib 111 extends in a non-closed shape along the circumferential direction of the matching groove 11, that is, the convex rib 11 extends in a C-shape or arc shape). It should be noted that the multiple convex ribs 111 can be arranged at equal intervals or at non-equal intervals, which can be specifically set according to actual use.

[0041] When the nut 100 is assembled with the fastener 302 (e.g., bolt) of the vehicle 300, the nut 100 is placed opposite to the free end of the bolt, and then the free end of the bolt is pushed into the matching groove 11 by external force. The assembled nut 100 is interference fit with the bolt through the rib 111. With such a configuration, the structure of the body 1 is simple, and it is convenient to install and disassemble, and it is also easy to process, thereby improving the production efficiency of the body 1, and then improving the production efficiency of the nut 100. In addition, the nut 100 can be applied to fasteners 302 with different thread pitches (e.g., coarse pitch bolts and fine pitch bolts), thereby avoiding the production of different nuts 100 corresponding to fasteners 302 with different thread pitches, simplifying the production steps, and improving the production efficiency. It also avoids the installation errors of the nut 100 and the bolts with different thread pitches, thereby reducing the difficulty of identification, reducing the difficulty of installation, further improving the efficiency of installation, and also improving the versatility of the nut 100. In addition, the ribs 111 extend along the circumference of the matching groove 11, increasing the contact area between the ribs 111 and the fastener 302 of the vehicle 300 along the circumference, thereby improving the stability of the assembly between the nut 100 and the fastener 302. However, it is not limited thereto. It should be noted that the number and arrangement of the ribs 111 can be specifically set according to actual use to better meet practical applications.

[0042] When the nut 100 is used in the nut tie assembly 200, and the nut tie assembly 200 is used in the vehicle 300, the nut 100 and the free end of the fastener 302 are assembled, the fastener 302 is inserted into the matching groove 11, and the plurality of convex ribs 111 are interference fit with the outer peripheral surface of the fastener 302, thereby improving the connection strength between the nut 100 and the fastener 302 and improving the use stability of the nut 100. Moreover, the bolt assembly of the nut 100 and the vehicle 300 can be directly pushed by external force, and the nut 100 and the fastener 302 of the vehicle 300 are easy to install, thereby reducing the difficulty of installing the nut 100 and the fastener 302 and improving the assembly efficiency of the nut 100 and the vehicle 300. In addition, the nut 100 increases the distance between the free end of the fastener 302 and the wiring harness tube 303 of the vehicle 300, avoiding interference between the wiring harness tube 303 and the free end of the fastener 302, thereby effectively preventing wear between the fastener 302 of the vehicle 300 and the wiring harness tube 303 of the vehicle 300 due to vibration of the vehicle 300, thereby extending the service life of the wiring harness tube 303 of the vehicle 300.

[0043] According to the nut 100 of the utility model, the structure of the body 1 is simple, the installation and disassembly are convenient, and the processing is also easy, thereby improving the production efficiency of the body 1. In addition, the nut 100 can be applied to fasteners 302 with different thread pitches, thereby avoiding the production of different types of nuts 100, improving the production efficiency, reducing the difficulty of identification, improving the accuracy of installation, and improving the versatility of the nut 100. In addition, when the nut 100 is used in the vehicle 300, the connection strength between the nut 100 and the fastener 302 is improved, and the use stability of the nut 100 is also improved.

[0044] According to some embodiments of the present invention, referring to Figure 2 and Figure 4 , the cross-sectional area of ​​the rib 111 gradually decreases along the radial direction of the body 1 toward the central axis of the body 1. Figure 2 and Figure 4 In the example, the cross-sectional area of ​​the rib 111 along the up-down direction on the side adjacent to the central axis of the body 1 is smaller than the cross-sectional area of ​​the rib 111 along the up-down direction on the side away from the central axis of the body 1 .

[0045] In this way, the cross-sectional area of ​​the side of the rib 111 adjacent to the central axis of the body 1 is smaller, so that when the nut 100 and the fastener 302 are installed, the resistance of the rib 111 to the fastener 302 can be reduced, which facilitates the rapid assembly of the nut 100 and the fastener 302, thereby further improving the assembly efficiency of the nut 100 and the fastener 302. In addition, the cross-sectional area of ​​the side of the rib 111 away from the central axis of the body 1 (i.e., the side of the rib 111 adjacent to the side wall of the matching groove 11) is larger, thereby increasing the contact area between the rib 111 and the side wall of the matching groove 11, improving the connection strength between the rib 111 and the side wall of the matching groove 11, thereby improving the stability of the use of the rib 111, and facilitating the normal use of the rib 111 for a long time. Moreover, the side of the rib 111 away from the central axis of the body 1 is not easy to bend, thereby improving the clamping degree of the rib 111 to the fastener 302, thereby further improving the assembly stability of the nut 100 and the fastener 302, and improving the stability of the use of the nut 100.

[0046] According to some embodiments of the present invention, referring to Figure 2 , Figure 4 and Figure 5 Each rib 111 has a first side surface 1111 and a second side surface 1112, one end of the first side surface 1111 and one end of the second side surface 1112 are respectively connected to the side wall of the matching groove 11, and the other end of the first side surface 1111 and the other end of the second side surface 1112 are close to each other.

[0047] For example, in Figure 2 In the example, the first side surface 1111 extends downwardly and obliquely from the side wall of the matching groove 11 to the center axis of the body 1, and the second side surface 1112 extends upwardly and obliquely from the side wall of the matching groove 11 to the center axis of the body 1. Figure 4 and Figure 5 In the example, the first side surface 1111 and the second side surface 1112 both extend upwardly along the direction from the side wall of the matching groove 11 to the centerline axis of the body 1, and the inclination angle of the second side surface 1112 is greater than the inclination angle of the first side surface 1111. Of course, the other end of the first side surface 1111 and the other end of the second side surface 1112 are close to each other to be connected or not connected. The first side surface 1111 and the second side surface 1112 can be set to extend straightly and obliquely, or extend in a curved shape, or extend in a serrated shape, etc., which is not specifically limited here, so as to facilitate the use of the nut 100.

[0048] Thus, the side of the rib 111 close to the side wall of the matching groove 11 is wider, and the side of the rib 111 away from the side wall of the matching groove 11 is narrower, so that the connection stability between the rib 111 and the side wall of the matching groove 11 is improved, and the clamping degree of the rib 111 on the vehicle 300 is improved, while ensuring that the nut 100 and the fastener 302 are easy to assemble, thereby further improving the performance of the nut 100 and the assembly stability of the nut 100 and the fastener 302. In addition, the upwardly inclined extension of the side surface of the rib 111 toward the lower side of the body 1 can guide the fastener 302 and reduce the resistance of the fastener 302 when it extends into the matching groove 11, thereby facilitating the rapid assembly of the fastener 302 and the nut 100, improving the assembly efficiency, and making the use of the nut 100 more convenient.

[0049] According to other embodiments of the present invention, each rib 111 has a first side surface 1111 and a second side surface 1112, one end of the first side surface 1111 and one end of the second side surface 1112 are respectively connected to the side wall of the matching groove 11, the other end of the first side surface 1111 extends along the radial direction of the body 1, and the other end of the second side surface 1112 extends obliquely toward the first side surface 1111 (not shown). For example, the first side surface 1111 extends approximately horizontally in the direction from the side wall of the matching groove 11 to the center axis of the body 1, and the second side surface 1112 extends obliquely upward in the direction from the side wall of the matching groove 11 to the center axis of the body 1. Among them, the arrangement of the first side surface 1111 and the second side surface 1112 includes the following situations: first, the above-mentioned other end of the first side surface 1111 (i.e., the end of the first side surface 1111 away from the side wall of the matching groove 11) and the above-mentioned other end of the second side surface 1112 (i.e., the end of the second side surface 1112 away from the side wall of the matching groove 11) are connected. Second, the other end of the first side surface 1111 and the other end of the second side surface 1112 are not connected.

[0050] Thus, the side of the rib 111 close to the side wall of the matching groove 11 is wider, and the side of the rib 111 away from the side wall of the matching groove 11 is narrower, so that the connection stability between the rib 111 and the side wall of the matching groove 11 is improved, and the clamping degree of the rib 111 on the vehicle 300 is improved, while ensuring that the nut 100 and the fastener 302 are easy to assemble, thereby further improving the performance of the nut 100 and the assembly stability of the nut 100 and the fastener 302. It should be noted that the extension of the first side surface 1111 and the extension of the second side surface 1112 can also be set as follows: the second side surface 1112 extends approximately horizontally in the direction from the side wall of the matching groove 11 to the center axis of the body 1, and the first side surface 1111 extends downwardly in the direction from the side wall of the matching groove 11 to the center axis of the body 1. In addition, the first side surface 1111 and the second side surface 1112 may be flat, wavy or stepped, and the surface area of ​​the first side surface 1111 and the surface area of ​​the second side surface 1112 may be the same or different, and the shape of the first side surface 1111 and the shape of the second side surface 1112 may be specifically set according to actual use conditions to better meet actual use, but is not limited thereto.

[0051] According to some embodiments of the present invention, referring to Figure 2 and Figure 4 , the other end of the first side surface 1111 is connected to the other end of the second side surface 1112. Figure 2 and Figure 4 In the example, one end of the first side surface 1111 away from the side wall of the matching groove 11 (i.e., the other end of the first side surface 1111) is connected to one end of the second side surface 1112 away from the side wall of the matching groove 11 (i.e., the other end of the second side surface 1112). In this way, the end of the rib 111 away from the side wall of the matching groove 11 is in a pointed shape, which further facilitates the end of the rib 111 away from the side wall of the matching groove 11 to be squeezed, thereby making it easier for the nut 100 and the fastener 302 to match, thereby further improving the assembly efficiency of the nut 100 and the fastener 302. In addition, the force of the rib 111 on the outer peripheral surface of the fastener 302 after the nut 100 and the fastener 302 are matched can also be increased, so that the assembly of the nut 100 and the fastener 302 is more secure. It should be noted that, here it is limited only that one end of the first side surface 1111 away from the side wall of the matching groove 11 is connected to one end of the second side surface 1112 away from the side wall of the matching groove 11, and the cross-sectional shape of the first side surface 1111 and the cross-sectional shape of the second side surface 1112 are straight extension or curved extension, which is not limited here.

[0052] According to some embodiments of the present invention, the first side 1111 is formed as a plane; and / or the second side 1112 is formed as a plane. For example, the first side 1111 and the second side 1112 are arranged in the following situations: first, only the first side 1111 is formed as a plane. Second, only the second side 1112 is formed as a plane. Third, the first side 1111 and the second side 1112 are respectively formed as planes (such as Figure 2 and Figure 4 As shown in FIG. 1 ). Thus, the first side surface 1111 and the second side surface 1112 have simple structures and are easy to form and process, thereby improving the production efficiency of the first side surface 1111 and the second side surface 1112, and further improving the production efficiency of the nut 100. In addition, the smoothness of the assembly of the nut 100 and the bolt is also improved, so that the fastener 302 is easily inserted into the matching groove 11, and the assembly efficiency of the nut 100 and the bolt is further improved.

[0053] Optionally, refer to Figure 5 The cross-sectional shape of the rib 111 is a triangle. Therefore, the side of the rib 111 away from the side wall of the matching groove 11 is sharp, which can ensure that the sharp corner is squeezed under the action of external force, making it easy to assemble the nut 100 and the fastener 302, and simplifying the structure of the rib 111, reducing the difficulty of producing the rib 111, which is conducive to improving the production efficiency of the nut 100.

[0054] According to some embodiments of the present invention, referring to Figure 1 , the convex rib 111 is an annular convex rib. For example, the annular convex rib 111 is annularly closed along the side wall of the matching groove 11. As a result, the contact area between the convex rib 111 and the outer peripheral surface of the fastener 302 is increased, thereby improving the interference fit effect between the convex rib 111 and the fastener 302, that is, the convex rib 111 clamps the fastener 302 along the circumferential direction of the side wall of the matching groove 11, thereby further improving the assembly effect of the nut 100 and the fastener 302.

[0055] According to other embodiments of the present invention, Figure 3 The rib 111 includes a plurality of sub-ribs 1113, and the plurality of sub-ribs 1113 are arranged at intervals along the circumference of the matching groove 11. Figure 3In the example, three sub-ribs 1113 are provided, and the three sub-ribs 1113 are arranged at intervals along the circumference of the matching groove 11. The arrangement of the sub-ribs 1113 includes the following situations: First, a plurality of sub-ribs 1113 form a circle along the circumference of the matching groove 11. Second, a plurality of sub-ribs 1113 form a fan-shaped along the circumference of the matching groove 11. Therefore, compared with the annular rib, the parts of the annular rib are restrained from bending during the assembly of the nut 100 and the fastener 302, and each sub-rib 1113 is easy to bend, so that the nut 100 and the bolt are easy to assemble, and the assembly efficiency of the nut 100 and the bolt is further improved. It should be noted that the number and arrangement of the sub-ribs 1113 can be set according to the actual use situation.

[0056] Further, refer to Figure 5 , a plurality of convex ribs 111 are arranged at equal intervals along the axial direction of the body 1, and the distance between two adjacent convex ribs 111 is d, where d satisfies: 1.5mm≤d≤2mm. Figure 5 In the example, when the distance between two adjacent convex ribs 111 is less than 1.5 mm, the two adjacent convex ribs 111 are arranged close to each other along the axial direction of the body 1, and the multiple convex ribs 111 are arranged densely along the axial direction of the body 1, thereby increasing the blocking effect of the multiple convex ribs 111 on the fastener 302 during the assembly of the nut 100 and the fastener 302, and increasing the difficulty of assembling the nut 100 and the fastener 302. When the distance between two adjacent convex ribs 111 is greater than 2 mm, the multiple convex ribs 111 are arranged sparsely along the axial direction of the body 1, thereby reducing the number of convex ribs 111, weakening the interference fit effect of the nut 100 and the fastener 302, and further reducing the stability of the assembly of the nut 100 and the fastener 302.

[0057] Therefore, by setting the distance d between two adjacent convex ribs 111 to satisfy: 1.5mm≤d≤2mm, the distance between two adjacent convex ribs 111 is set reasonably, and the number of convex ribs 111 is set reasonably, so that during the assembly process of the nut 100 and the fastener 302, the blocking effect of the multiple convex ribs 111 on the fastener 302 is weakened, the assembly difficulty of the nut 100 and the fastener 302 is reduced, and the assembly efficiency of the nut 100 and the fastener 302 is improved. In addition, the interference fit effect of the nut 100 and the fastener 302 is enhanced, thereby improving the stability of the assembly of the nut 100 and the fastener 302.

[0058] According to some embodiments of the present invention, referring to Figure 4 , a connecting portion 12 is provided on the other side of the body 1, and at least one connecting hole 121 is formed on the connecting portion 12, and the connecting hole 121 penetrates the outer peripheral surface of the connecting portion 12 along the radial direction of the connecting portion 12. For example, Figure 4In the example, the connecting portion 12 is located on the side of the body 1 away from the body 1 where the matching groove 11 is provided. Therefore, when the nut 100 is used in the nut tie assembly 200, one end of the tie 201 can pass through the connecting hole 121, so as to facilitate the assembly of the tie 201 and the nut 100, thereby improving the assembly efficiency of the nut 100 and the tie 201, and also facilitating the later use of the tie 201. For example, a plurality of connecting holes 121 may be provided on the connecting portion 12, and the plurality of connecting holes 121 are cross-arranged. Two connecting holes 121 may be provided, and the two connecting holes 121 are arranged in a cross shape. Therefore, it is convenient for the tie 201 to pass through different connecting holes 121 according to actual use conditions, thereby improving the convenience of using the tie 201. But it is not limited to this. It should be noted that the number and arrangement of the connecting holes 121 can be specifically set according to actual use to better meet practical applications.

[0059] Optionally, refer to Figure 3 and Figure 4 , the above-mentioned side of the body 1 is provided with a plurality of weight-reducing grooves 13, and the plurality of weight-reducing grooves 13 are arranged at intervals along the circumference of the body 1, and the weight-reducing grooves 13 are located radially outside the matching groove 11. Six weight-reducing grooves 13 can be provided. Thus, the weight-reducing hole can reduce the weight of the nut 100, thereby facilitating the transportation and use of the nut 100. In addition, the material usage of the nut 100 is also reduced, thereby reducing the production cost of the nut 100. But not limited to this. It should be noted that the number and arrangement of the weight-reducing grooves 13 can be specifically set according to actual use to better meet practical applications.

[0060] Optionally, the nut 100 may be a plastic part. Plastic parts are easy to mold and have wear resistance, so that the nut 100 is easy to mold, which improves the production rate of the nut 100. Moreover, the service life of the nut 100 is also extended. In addition, when the nut 100 is used in the vehicle 300, when the vehicle 300 vibrates, the wear degree of the nut 100 and the wiring harness tube 303 is reduced, thereby reducing the degree of damage to the wiring harness tube 303 and extending the service life of the wiring harness tube 303. For example, the cross-sectional shape of the lower end of the nut 100 may be circular or hexagonal. But it is not limited to this.

[0061] According to the nut cable tie assembly 200 of the second aspect of the utility model, refer to Figure 6 and Figure 7 , including a nut 100 and a cable tie 201, the nut 100 is the nut 100 according to the first aspect embodiment of the utility model, and a part of the cable tie 201 passes through the connecting hole 121 of the nut 100 and is connected to the nut 100.

[0062] According to the nut cable tie assembly 200 of the embodiment of the utility model, by adopting the above-mentioned nut 100, it is easy to assemble the cable tie 201 and the nut 100, thereby improving the assembly efficiency of the cable tie 201 and the nut 100. In addition, by adopting the above-mentioned nut 100, the versatility of the use of the nut cable tie assembly 200 is improved. Moreover, when the nut cable tie assembly 200 is used in the vehicle 300, the nut cable tie assembly 200 is easy to assemble with the fastener 302, thereby improving the assembly efficiency of the nut cable tie assembly 200 and the fastener 302.

[0063] Optionally, refer to Figure 7 A protrusion 202 is formed at the center of the side wall of the connection hole 121. The protrusion 202 protrudes from the side wall of the connection hole 121. The protrusion 202 is located on the lower side wall of the connection hole 121, and the protrusion 202 cooperates with the teeth of the cable tie 201.
