[0012] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] Please see Figure 1-6This utility model provides a technical solution: a motor vehicle license plate anti-theft fixing device, comprising: a fixing bolt 1, the fixing bolt 1 being made of medium carbon steel, the outer wall of the fixing bolt 1 having grooves arranged in a circumferential array; a fixing device 2, the fixing device 2 being threadedly connected to the fixing bolt 1; the fixing device 2 including a fixing nut 21, the inner wall of the fixing nut 21 being rotatably connected to a latch 22; a return spring 23 being fixedly connected to the inner wall of the fixing nut 21, the side of the return spring 23 away from the fixing nut 21 being fixedly connected to the outer wall of the latch 22; since the fixing bolt 1 is made of medium carbon steel, which has good structural strength and hardness, the structural strength of the fixing bolt 1 is guaranteed.

[0014] The fixing nut 21 is engaged with the fixing bolt 1. The fixing nut 21 is made of medium carbon steel. The fixing bolt 1 is fitted with a protective washer 6. A retaining ring 5 is engaged with the inner wall of the protective washer 6. A protective cover 4 is fixedly connected to the top of the retaining ring 5. A compression spring 7 is provided on the top of the fixing bolt 1. The top of the compression spring 7 is fixedly connected to the bottom of the protective cover 4. The compression spring 7 plays a buffering role in the high vibration environment of the motor vehicle operation, making the fixing bolt 1 less prone to loosening.

[0015] The outer side of the fixing device 2 is fitted with a protective retaining ring 3. The outer wall of the fixing bolt 1 is engaged with the vehicle license plate 8 and the outer wall of the fixing bolt 1 is engaged with the license plate mounting plate 9. The outer wall of the retaining tongue 22 is engaged with the groove of the fixing bolt 1. The retaining tongue 22 is engaged with the groove of the fixing bolt 1. At the same time, because the retaining tongue 22 adopts a bevel design, the fixing bolt 1 can only rotate in the forward direction.

[0016] When using it, first, put the protective washer 6 onto the fixing bolt 1. The function of the protective washer 6 is to protect the top of the fixing bolt 1 when it is used with other components.

[0017] Next, insert the fixing bolt 1 into the vehicle license plate 8 and the license plate mounting plate 9 in sequence. This step is to make a preliminary connection between the vehicle license plate 8 and the mounting part of the vehicle, laying the foundation for the subsequent tightening operation.

[0018] Subsequently, the protective retaining ring 3 is put into the fixing device 2. The protective retaining ring 3 mainly serves to protect the fixing nut 21 and provides a certain degree of protection for the fixing device 2.

[0019] Next, the fixing device 2 with the protective retaining ring 3 is tightened to the fixing bolt 1. During the tightening process, the return spring 23 will push the latch 22 to lock into the grooves arranged in a circumferential array on the outer wall of the fixing bolt 1. It is worth mentioning that the latch 22 adopts a beveled design, which makes the fixing bolt 1 only able to rotate inward and not outward, thus playing a certain role in preventing theft.

[0020] Finally, the protective cover 4, which is fixedly connected to the snap ring 5 and the compression spring 7, is snapped into the protective washer 6. Because the snap ring 5 is engaged with the protective washer 6, the top of the fixing bolt 1 is not easily opened, further enhancing the anti-theft performance. At the same time, the compression spring 7 can play a shock-absorbing role, preventing the bolt from loosening due to vibrations during vehicle operation.
