Description

Technical Field

[0001] The utility model relates to the field of automobile accessories, in particular to an anti-theft fixing device for license plates. Background Art

[0002] A license plate is an identifier used to identify the owner of a motor vehicle, vehicle information, and registration location. It is usually made of metal or plastic material, with a series of letters, numbers, and symbols printed on it to facilitate the identification and management of vehicles by traffic management departments and law enforcement agencies. License plates are fixed to the outside of the vehicle and are vulnerable to theft or replacement. Stolen license plates can be used to commit illegal activities or to forge vehicle identities. Therefore, installing an anti-theft fixing device can effectively prevent license plates from being stolen or replaced.

[0003] An existing anti-theft fixing device for license plates is designed to have one end of a fastening cover as a solid arc-shaped surface when in use, so that the arc-shaped surface and the outer wall of the fastening cover have an arc, so it is difficult to pry it open with needle-nosed pliers and it is not easy to deform. The arc-shaped surface is a seamless surface, which plays a good anti-theft role.

[0004] However, this method cannot provide a buffer for the license plate when in use. The lack of a buffering fixture means that the license plate is directly exposed to external shocks and vibrations. When the vehicle is driving or parked, road bumps, collisions or vibrations will be directly transmitted to the license plate, causing damage, wear, scratches or even deformation of the license plate, which will affect the appearance and recognition accuracy of the license plate. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an anti-theft fixing device for a license plate, aiming to improve the problem that the anti-theft fixing device for a license plate in the prior art cannot play a buffering role on the license plate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-theft fixing device for a license plate, comprising a protective frame, a mounting box fixedly connected to the rear of the protective frame, fixing plates fixedly connected to the inner sides of the mounting box, a plurality of fixing plates fixedly connected to the front of the fixing boxes, a movable block slidably connected to the interior of the fixing box, a push plate fixedly connected to the front of the movable block, a limiting assembly fixedly connected to the bottom of the push plate, and a buffer spring arranged inside the fixing box.

[0007] Furthermore, a license plate body is arranged inside the protection frame, and anti-theft bolts are threadedly connected on both sides of the protection frame and the license plate body.

[0008] Furthermore, the limiting assembly includes a limiting block, the limiting block is fixedly connected to the bottom of the push plate, and the limiting block is slidably connected to the outside of the limiting rod.

[0009] Furthermore, a groove is provided inside the fixing plate, and a limiting rod is fixedly connected inside the groove.

[0010] Furthermore, one end of the buffer spring is fixedly connected to the interior of the fixed box, and the other end of the buffer spring is fixedly connected to the rear of the movable block.

[0011] Furthermore, push rods are fixedly connected to both sides of the rear portion of the license plate body.

[0012] Furthermore, the plurality of push rods are in contact with the push plate, and the license plate body is made of an acrylic plate.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, when the license plate body is hit, the push rod will move toward the inside of the installation box, squeezing the push plate, and the push plate pushes the movable block to move backward, squeezing the buffer spring. Under the elastic action of the buffer spring, a buffer effect is achieved. This buffer mechanism can reduce the damage to the surface of the license plate body caused by the impact force, extend its service life, and reduce the cost of maintenance and replacement.

[0015] 2. In the utility model, the license plate body is placed in the protection frame, and the protection frame and the license plate body are fixed with anti-theft bolts. This fixing method can effectively prevent disassembly by ordinary tools or screwdrivers, thereby improving the anti-theft capability of the license plate and the safety of the vehicle.

[0022] 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.

[0023] Reference Figure 2-Figure 4 The utility model provides an embodiment: an anti-theft fixing device for a license plate, comprising a protection frame 1, a mounting box 5 is fixedly connected to the rear of the protection frame 1, a fixing plate 6 is fixedly connected to the inner sides of the mounting box 5, a plurality of fixing plates 6 are fixedly connected to the front of the fixing boxes 7, a movable block 8 is slidably connected to the interior of the fixing box 7, a push plate 9 is fixedly connected to the front of the movable block 8, a limiting assembly is fixedly connected to the bottom of the push plate 9, a buffer spring 12 is arranged inside the fixing box 7, the limiting assembly comprises a limiting block 10, the limiting block 10 is fixedly connected to the bottom of the push plate 9, the limiting block 10 is slidably connected to the outside of the limiting rod 11, a groove is provided inside the fixing plate 6, the limiting rod 11 is fixedly connected inside the groove, one end of the buffer spring 12 is fixedly connected to the interior of the fixing box 7, the other end of the buffer spring 12 is fixedly connected to the rear of the movable block 8, push rods 4 are fixedly connected to the rear sides of the license plate body 3, and a plurality of push rods 4 are in contact with the push plate 9.

[0024] When the vehicle is driving, the license plate body 3 will be hit from various directions, such as stones, branches or other objects. At this time, the license plate body 3 will drive the push rod 4 to move toward the inside of the installation box 5. During the movement, the push rod 4 will squeeze the push plate 9. Since the push plate 9 is squeezed by the push rod 4, it will move backward and drive the limit block 10 to slide outside the limit rod 11. The limit block 10 can not only ensure the stability of the push plate 9 during the movement, but also effectively control the moving distance and speed of the push plate 9. Under the action of the limit block 10, the push plate 9 continues to drive the movable block 8 to move backward. During the process, the movable block 8 will squeeze the buffer spring 12 to cause it to deform. The buffer spring 12 is the core component of this device. It has good elasticity and buffering performance. When squeezed, the buffer spring 12 can effectively absorb and disperse the impact force and reduce the impact on the license plate body 3. Under the elastic action of the buffer spring 12, the movable block 8 will gradually move to the inside of the fixed box 7, and the buffer spring 12 will gradually restore its original shape. By effectively absorbing and dispersing the impact force, the buffer spring 12 can significantly reduce the extent to which the impact force is transmitted to the surface of the license plate body 3, thereby protecting the license plate body 3 from damage.

[0025] Reference Figure 1 A license plate body 3 is arranged inside the protection frame 1, and anti-theft bolts 2 are threadedly connected to both sides of the protection frame 1 and the license plate body 3, and the material of the license plate body 3 is an acrylic plate.

[0026] The license plate body 3 is placed inside the protective frame 1. The protective frame 1 is made of strong and durable materials, has strong pressure resistance and impact resistance, and can effectively protect the license plate body 3 from being damaged or stolen. After the license plate body 3 is placed inside the protective frame 1, it is tightly fixed to the protective frame 1 using special anti-theft bolts 2. The anti-theft bolts 2 adopt a special structural design, which makes it difficult to be easily disassembled by ordinary tools or screwdrivers, thereby greatly improving the anti-theft performance of the license plate. Through this fixing method, the license plate body 3 is firmly fixed inside the protective frame 1, which can not only effectively prevent lawless elements from using tools to disassemble it, but also reduce the damage to the license plate caused by natural factors such as wind, sun, rain, snow, etc.

[0027] Working principle: First, place the license plate body 3 inside the protection frame 1, rotate the anti-theft bolt 2 into the protection frame 1 and the license plate body 3, and fix the protection frame 1 and the license plate body 3, so as to effectively fix the license plate body 3 and effectively prevent it from being disassembled by ordinary tools or screwdrivers, thereby improving the anti-theft ability of the license plate body 3 and increasing the safety of the vehicle. When the license plate body 3 is hit, the license plate body 3 drives the push rod 4 to move toward the inside of the installation box 5, and the push rod 4 squeezes the push plate 9, which is squeezed and moves backward. The movable block 8 moves to the inside of the fixed box 7, and the buffer spring 12 plays a buffering role, thereby effectively buffering the license plate body 3, reducing the impact force transmitted to the surface of the license plate body 3, protecting the surface of the license plate body 3 from damage, extending the service life of the license plate body 3, and reducing the frequency and cost of replacement and maintenance.

[0028] 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.
