[0032] Next, reference is made to Figures 1-4 Describe the anti-rotation bolt member 100 according to an embodiment of the present utility model.

[0033] As Figure 1 shown, the anti-rotation bolt member 100 according to an embodiment of the present utility model includes an anti-rotation portion 1 and a bolt portion 2.

[0034] Specifically, as Figure 1 and Figure 2 shown, the anti-rotation bolt member 100 is adapted to be assembled with the mounting member 200. The anti-rotation portion 1 includes an anti-rotation body 11 and a slider 12. An anti-rotation groove 111 is provided on the anti-rotation body 11. One side of the anti-rotation groove 111 in the first direction (as Figure 1 shown) and the second direction (as Figure 1One side of the slider 12 is open, so that the slider 12 can be installed in the anti-rotation groove 111. Along the first direction, the position of the slider 12 relative to the anti-rotation body 11 is adjustable, so that the slider 12 of the anti-rotation bolt member 100 can be adapted to the mounting members 200 of different sizes for assembly, thereby increasing the adaptability of the anti-rotation bolt member 100. Part of the slider 12 can extend out of the anti-rotation groove 111 and beyond the anti-rotation body 11. Along the second direction, the mounting member 200 has a limiting protrusion 201 extending toward the slider 12, and the slider 12 can stop against the limiting protrusion 201, so that the slider 12 is better limited.

[0035] like Figure 1 and Figure 3 As shown, the bolt portion 2 extends along the second direction and one end is connected to the side surface of the anti-rotation body 11 away from the anti-rotation groove 111, and the bolt portion 2 is suitable for being inserted into the mounting member 200, and the first direction is perpendicular to the second direction. It can be understood that a nut is disposed on the outer sleeve of the bolt portion 2 of the anti-rotation bolt member 100, and the nut limits the mounting member 200 between the nut and the anti-rotation portion 1, so as to realize the assembly of the anti-rotation bolt member 100 and the mounting member 200.

[0036] When the nut is rotated and tightened on the bolt part 2, the nut applies a rotational torque to the bolt part 2, and the bolt part 2 and the nut rotate in the same direction. The anti-rotation body 11 in the anti-rotation part 1 rotates along with the bolt part 2, and the slider 12 abuts against the peripheral wall of the anti-rotation groove 111, which can prevent the anti-rotation part 1 from rotating, thereby increasing the reliability of the installation position of the anti-rotation bolt member 100.

[0037] According to the anti-rotation bolt member 100 of the embodiment of the utility model, by adjusting the position of the slider 12 relative to the anti-rotation body 11 along the first direction, the slider 12 can extend partly out of the anti-rotation groove 111 and beyond the anti-rotation body 11, the bolt portion 2 extends along the second direction and one end is connected to the surface of the side of the anti-rotation body 11 away from the anti-rotation groove 111, the bolt portion 2 is suitable for being inserted into the mounting member 200, and a nut is provided on the outer sleeve of the bolt portion 2 of the anti-rotation bolt member 100, and the nut limits the mounting member 200 between the nut and the anti-rotation portion 1, so as to realize the assembly of the anti-rotation bolt member 100 and the mounting member 200. When the nut is rotated and tightened on the bolt portion 2, the nut applies a rotation torque to the bolt portion 2, and the bolt portion 2 and the nut rotate in the same direction, the anti-rotation body 11 in the anti-rotation portion 1 rotates with the bolt portion 2, and the slider 12 abuts against the peripheral wall of the anti-rotation groove 111, so as to prevent the anti-rotation portion 1 from rotating, thereby increasing the reliability of the installation position of the anti-rotation bolt member 100.

[0038] In addition, along the first direction, the effective sliding stroke of the slider 12 should be greater than the gap between the anti-rotation body 11 and the mounting member 200 , so as to ensure the limiting effect of the mounting member 200 on the slider 12 .

[0039] Moreover, there is no need to add a limiting structure to the mounting member 200, and the anti-rotation during installation can be achieved through the structure of the anti-rotation bolt member 100 itself, making the assembly of the mounting member 200 and the anti-rotation bolt member 100 relatively simple and reliable.

[0040] When the anti-rotation bolt member 100 is stressed and twisted, its twisting angle is small, generally not exceeding 1.5°.

[0041] In some embodiments of the present invention, as Figure 1 and Figure 4 shown, at least one of the inner walls of the anti-rotation groove 111 opposite to each other in the third direction (as Figure 1 shown) is provided with a plurality of limiting teeth 112, the plurality of limiting teeth 112 are arranged at intervals in the first direction, the slider 12 is movably arranged in the anti-rotation groove 111 in the first direction, and the slider 12 is configured to abut against one of the two surfaces opposite to each other in the first direction of the limiting teeth 112 after rotation, so as to limit the rotation of the slider 12. The first direction, the second direction and the third direction are perpendicular to each other in pairs.

[0042] Specifically, when the nut rotates and tightens on the bolt portion 2, the nut applies a rotational torque to the bolt portion 2, the bolt portion 2 and the nut rotate in the same direction, the anti-rotation body 11 in the anti-rotation portion 1 rotates along with the bolt portion 2, the anti-rotation body 11 undergoes a slight twist, the limiting teeth 112 abut against the slider 12, and the slider 12 meshes with and presses against the limiting teeth 112 to prevent the anti-rotation bolt member 100 from rotating.

[0043] The slider 12 can adjust its position in the anti-rotation groove 111 according to the size of the mounting member 200. At least one of the inner walls of the anti-rotation groove 111 opposite to each other in the third direction is provided with a plurality of limiting teeth 112, so that when the slider 12 is located at different positions, it can abut against one of the two surfaces opposite to each other in the first direction of the limiting teeth 112 after the anti-rotation body 11 twists, and can avoid large rotation of the anti-rotation bolt member 100.

[0044] In this embodiment, as Figure 1 and Figure 4 shown, a plurality of limiting teeth 112 are provided on both inner walls of the anti-rotation groove 111 opposite to each other in the third direction, so that when the anti-rotation body 11 twists clockwise or counterclockwise, it can abut against one of the two surfaces opposite to each other in the first direction of the limiting teeth 112, and can avoid large rotation of the anti-rotation bolt member 100.

[0045] In this embodiment, the limiting teeth 112 are right-angle teeth or obtuse-angle teeth, which can ensure the strength of the limiting teeth 112 and avoid breakage of the limiting teeth 112.

[0046] Furthermore, along the third direction, a gap is provided between the slider 12 and the limiting tooth 112, so that the slider 12 can slide conveniently along the third direction, and the slider 12 can adjust its position in the anti-rotation groove 111 according to the size of the mounting member 200, and the slider 12 and the anti-rotation body 11 can generate a slight twist, so that the slider 12 and the limiting tooth 112 can stop on one of the two surfaces opposite to each other along the first direction.

[0047] In some embodiments of the present invention, Figure 1 As shown, along the first direction, the end of the slider 12 away from the side wall of the anti-rotation groove 111 has a notch 121, and the notch 121 is spaced apart from the two ends of the slider 12 in the third direction. At this time, there are two limit blocks 123 at the two ends of the third direction of the end of the slider 12 away from the side wall of the anti-rotation groove 111, and the limit blocks 123 can stop against the protrusion 113 of the mounting member 200, which can better limit the slider 12. When the two limit blocks 123 of the slider 12 are subjected to the same force, the slider 12 can slide freely in the limit groove to adapt to the different installation gaps between the anti-rotation bolt member 100 and the mounting member 200; when the two limit blocks 123 of the slider 12 are subjected to uneven force, the anti-rotation body 11 is slightly twisted, and the slider 12 is engaged and squeezed with the limit teeth 112 to prevent the anti-rotation bolt member 100 from rotating.

[0048] In some embodiments of the present invention, Figure 1 As shown, a first positioning structure is provided on the anti-rotation body 11, and a second positioning structure is provided on the slider 12. The first positioning structure and the second positioning structure cooperate to limit the travel of the slider 12 extending out of the anti-rotation groove 111, thereby preventing the slider 12 from escaping from the anti-rotation groove 111 and increasing the reliability of the installation position of the slider 12.

[0049] Furthermore, if Figure 1 As shown, one of the first positioning structure and the second positioning structure is formed as a slide groove 122 extending along the first direction, and the other is formed as a protrusion 113 matched with the slide groove 122. When the slider 12 slides to the limit position matched with the anti-rotation body 11, the slide groove 122 cooperates with the protrusion 113 to limit the continued sliding of the slider 12, preventing the slider 12 from escaping from the anti-rotation groove 111, thereby increasing the reliability of the installation position of the slider 12, and the structure of the slider 12 that limits the travel of the slider 12 extending out of the anti-rotation groove 111 is relatively simple and reliable.

[0050] Furthermore, if Figure 1As shown, the first positioning structure is formed as a protrusion 113, and the second positioning structure is formed as a chute 122. Along the first direction, one side of the chute 122 facing away from the side wall of the anti-rotation groove 111 is open. When the slider 12 slides toward the side away from the side wall of the anti-rotation groove 111, the protrusion 113 enters the chute 122 from the open mouth of the chute 122 and abuts against the side wall of the chute 122 close to the side wall of the anti-rotation groove 111, preventing the slider 12 from disengaging from the anti-rotation groove 111, increasing the reliability of the installation position of the slider 12, and the structure for restricting the stroke of the slider 12 from protruding out of the anti-rotation groove 111 is relatively simple and reliable.

[0051] In some embodiments of the present invention, as Figure 1 and Figure 3 shown, the anti-rotation bolt member 100 further includes an elastic member 3. The elastic member 3 is connected to the anti-rotation body 11 and the slider 12 and is used to drive the slider 12 to extend toward the open mouth in the first direction, which can automatically match the gap between the slider 12 and the limit protrusion 201, facilitating the change of the position of the slider 12 of the anti-rotation bolt member 100, so that the slider 12 of the anti-rotation bolt member 100 can be more conveniently adapted to different sizes of mounting members 200 for assembly, increasing the adaptability of the anti-rotation bolt member 100.

[0052] In some embodiments of the present invention, as Figure 1 shown, the elastic member 3 is disposed on the side of the anti-rotation groove 111 away from the open mouth, facilitating driving the slider 12 to extend toward the open mouth in the first direction, facilitating the change of the position of the slider 12 of the anti-rotation bolt member 100, so that the slider 12 of the anti-rotation bolt member 100 can be more conveniently adapted to different sizes of mounting members 200 for assembly, increasing the adaptability of the anti-rotation bolt member 100.

[0053] A vehicle according to an embodiment of the present invention includes the above anti-rotation bolt member 100.

[0054] In a vehicle according to an embodiment of the present invention, by placing the slider 12 in a position where its position relative to the anti-rotation body 11 is adjustable along the first direction, a part of the slider 12 can extend out of the anti-rotation groove 111 and exceed the anti-rotation body 11. The bolt portion 2 extends along the second direction and one end is connected to the surface of the anti-rotation body 11 facing away from the anti-rotation groove 111. The bolt portion 2 is adapted to pass through the mounting member 200. A nut is sleeved outside the bolt portion 2 of the anti-rotation bolt member 100, and the nut limits the mounting member 200 between the nut and the anti-rotation portion 1, realizing the assembly of the anti-rotation bolt member 100 and the mounting member 200. When the nut rotates and tightens on the bolt portion 2, the nut applies a rotational torque to the bolt portion 2, and the bolt portion 2 and the nut rotate in the same direction. The anti-rotation body 11 in the anti-rotation portion 1 rotates along with the bolt portion 2, and the slider 12 abuts against the peripheral wall of the anti-rotation groove 111, which can prevent the anti-rotation portion 1 from rotating, increasing the reliability of the installation position of the anti-rotation bolt member 100.
