[0001] The utility model relates to the technical field of automobile accessories, in particular to a novel tire bolt anti-loosening structure. Background Art

[0002] When a tire of a conventional vehicle is assembled to an axle, a brake drum is usually assembled on the axle first, and then the wheel shell and the brake drum are locked together into one, so that the vehicle can brake by utilizing the braking effect of the brake drum when driving.

[0003] When installing a tire, most of the surfaces of the brake drum are provided with bolts corresponding to the tire hub. When installing the car tire, nuts are needed to fix the tire on the brake drum.

[0004] When installing nuts on existing automobile bolts, most of them directly rotate the nuts on the surface of the bolts. However, with frequent disassembly and assembly, the bolts need to be frequently tightened. Frequent tightening causes friction between the nuts and bolts, resulting in wear and tear, thereby reducing the fixing effect. The bolts may become loose, thereby affecting the life safety of the driver. When the bolts and nuts are subjected to impact or collision during work, the bolts and nuts are easily misaligned, resulting in damage, which affects the service life. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 and Figure 5 The utility model provides a novel tire bolt anti-loosening structure, including a bolt 1, a nut 2 is threadedly connected to the surface of the bolt 1, and the inner wall of the bottom end of the nut 2 is elastically connected to a sliding column 11 through a reset spring 10. When the nut 2 moves on the surface of the bolt 1, the buffer sheet 12 will first contact the tire surface, so that the buffer sheet 12 is squeezed and pushes the sliding column 11 to move on the inner wall of the nut 2.

[0026] See also Figure 5 One end of the return spring 10 is fixedly connected to the top of the outer wall of the sliding column 11, and the other end of the return spring 10 is fixedly connected to the inner wall of the bottom end of the nut 2. After the nut 2 is threadedly connected and locked on the surface of the bolt 1, the return spring 10 will always be in a compressed state. When the nut 2 is removed from the surface of the bolt 1, the elastic action of the return spring 10 restores the sliding column 11 together with the buffer plate 12 to their initial positions. The sliding column 11 is slidably connected to the inner wall of the bottom end of the nut 2, and the bottom end of the outer wall of the sliding column 11 is fixedly connected with the buffer plate 12. Through the cooperation of the buffer plate 12 and the return spring 10, the impact force received by the bolt 1 and the nut 2 during work can be effectively reduced.

[0027] See also Figure 2 and Figure 3The inner wall of the nut 2 is fixedly connected with a guide plate 3, and the surface of the guide plate 3 is provided with three groups of linear guide grooves, so that when the rotating plate 4 rotates, the three groups of guide posts 7 can move back and forth inside the linear guide grooves, and the top of the outer wall of the guide plate 3 contacts with three groups of friction blocks 6, and the surface of the friction blocks 6 contacts with the bolt 1, and the three groups of friction blocks 6 contact with the surface of the bolt 1, so as to increase the friction force on the bolt 1, to prevent the thread of the bolt 1 from being damaged during repeated disassembly, thereby reducing the locking performance of the bolt 1, and the bottom end of the outer wall of the three groups of friction blocks 6 is fixedly connected with a guide post 7, which passes through and is slidably connected to the inner wall of the guide plate 3, and the guide post 7 is slidably connected to the inner wall of the rotating plate 4, and the surface of the rotating plate 4 is provided with three groups of arc grooves, and the three groups of guide posts 7 are moved inside the arc grooves by rotating the rotating plate 4, so as to move back and forth in the linear guide grooves of the guide plate 3.

[0028] See also Figure 3 and Figure 4 The inner wall of the nut 2 is rotatably connected with a rotating disk 4, and the outer side wall of the rotating disk 4 is fixedly connected with a rotating block 5. By rotating the rotating block 5, the rotating disk 4 can be driven to rotate inside the nut 2. The rotating block 5 is slidably connected to the inner wall of the nut 2. A sliding groove is opened on the surface of the nut 2, and the rotating block 5 can only move on the inner wall of the sliding groove.

[0029] See also Figure 4 The inner wall of the rotating block 5 is provided with a limiting mechanism, which includes a clamping block 9, which is elastically connected to the inner wall of the rotating block 5 by a limiting spring 8, one end of the limiting spring 8 is fixedly connected to the bottom end of the inner wall of the rotating block 5, and the other end of the limiting spring 8 is fixedly connected to the bottom end of the outer wall of the clamping block 9. By pressing the clamping block 9 to move on the inner wall of the rotating block 5, the rotating disk 4 can be rotated to rotate. When the clamping block 9 is released when it is adjusted to a suitable position, it will be elastically acted upon by the limiting spring 8 to restore it to its initial position to be plugged into the slot 13 at the current position to fix the current position of the rotating block 5 and the rotating disk 4. The clamping block 9 is slidably connected to the inner wall of the rotating block 5, and the clamping block 9 is plugged into the slot 13. The plugging between the two allows the rotation of the rotating disk 4 to fix the clamping position of the bolt 1 with the friction block 6, so as to prevent the friction block 6 from canceling contact with the bolt 1 during use. The inner wall of the nut 2 is provided with a plurality of sets of slots 13.

[0030] Working principle: First, most of the bolts 1 are fixed on the flange of the car. At this time, the tire is installed on the flange of the car and passes through the bolt 1. Then the internal thread of the nut 2 is rotated to the surface of the bolt 1. When the nut 2 is rotated to the bottom, the buffer plate 12 will first contact the surface of the tire, thereby squeezing the buffer plate 12 to drive the sliding column 11 to move inward on the inner wall of the nut 2. At this time, the return spring 10 will be elastically compressed, which can effectively reduce the impact force on the bolt 1 and the nut 2 during work.

[0031] When the nut 2 is completely rotated and installed to the surface of the bolt 1, the block 9 is pressed again to move on the inner wall of the rotating block 5 to disengage the block 9 from the slot 13 at the current position of the nut 2, and the rotating block 5 is rotated to drive the rotating disk 4 to rotate. When it rotates, the three groups of guide columns 7 sliding on the inner wall will slide in the arc groove on its surface. Due to the setting of the linear guide groove of the guide disk 3, the guide column 7 will drive the friction block 6 to move in the linear guide groove, so that the friction block 6 is in contact with the surface of the bolt 1, so as to increase the contact area between the friction block 6 and the bolt 1, to increase the tightness of the bolt 1, to prevent the tire from rotating for a long time and causing the nut 2 to loosen. At this time, the block 9 is released and it will be affected by the elastic action of the limit spring 8 to restore it to its initial position to be plugged into the slot 13 at the current position of the nut 2, thereby fixing the position of the rotating disk 4 and the friction block 6.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
