Description

Technical Field

[0001] The utility model relates to the technical field of vehicle license plate fixing and installation, in particular to a vehicle license plate fixing and sealing device. Background Art

[0002] Motor vehicles have become a very common means of transportation and are growing in number. However, motor vehicle license plates are often stolen by criminals and used for illegal activities. A considerable number of car owners change license plates privately, often using one license plate on different vehicles or using multiple different license plates on the same vehicle to circumvent traffic regulations, which seriously damages people's lives and property safety and causes serious consequences.

[0003] The license plate on a traditional motor vehicle is usually fixed to the license plate mounting frame with ordinary screw connectors, which are generally composed of nuts, washers, bolts and decorative nuts. The license plate can be easily removed by removing the screw connectors with tools such as ordinary wrenches or screwdrivers. In general, this type of fixed sealing method is easy to pry open the sealing cap and disassemble, and it is difficult to prevent the license plate from being stolen or tampered with.

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] like Figure 1-4 A vehicle license plate sealing device shown in the figure includes a base 1, a cover cap 2, an inner fastener 3 and an anti-theft screw 4. The inner cavity 11 of the base 1 is provided with an inner hole 12 for a discount piece 31 at one end of the inner fastener 3 to pass through, and the other end of the inner fastener 3 is provided with a folded portion 32. The inner wall 22 at the opening 21 of the cover cap 2 is a shrinking inward structure with a small outside and a large inside, and the inner wall 22 cooperates with the folded portion 32. A nut groove 33 is also provided on the inner fastener 3, and the nut portion 41 of the anti-theft screw 4 is located in the nut groove 33, and the front end of the screw is arranged through the inner hole 12.

[0019] By adopting the above scheme, the user pre-processes the connection between the inner fastener 3 and the base 1, passes the discount piece 31 through the inner hole 12, and then the discount piece 31 with a notch in the circumferential direction is turned outward under the action of the tool to fit the lower bottom surface of the base 1, and is clamped and fixed on the base 1 with the base 1 of the inner fastener 3, and then the anti-theft screw 4 passes through the through hole in the middle of the discount piece 31 of the inner fastener 3 corresponding to the inner hole 12, and the anti-theft screw 4 is connected to the car shell to fix the base 1 with the inner fastener 3 on the car shell first, and then, the cover cap 2 is buckled on the base 1, and the opening 21 of the buckled cover cap 2 is slightly smaller than the opening 21 of the cover cap 2 at this time. The opened inverted folded portion 32, under the pressure of the opening 21, the inverted folded portion 32 swings inward and shrinks. Based on the structure that the inner wall 22 of the cap 2 shrinks inward along the opening 21, after the cap 2 of this embodiment is fastened with the inner fastener 3, the end of the inverted folded portion 32 presses on the inclined inner wall 22 of the cap 2 to form a disengagement limit after the cap 2 is fastened. After the cap 2 is fastened, the end face of the cap 2 is flush with or lower than the edge of the base 1, and the gap between the two is narrow, and the disassembly tool cannot be inserted, which ensures the stable installation of the sealing device and the anti-theft and anti-dismantling of the license plate.

[0020] As a further configuration of the above scheme, a pad 43 is further provided between the nut portion 41 and the bottom wall of the inner fastener 3 . The pad 43 is made of plastic material, and the thickness of the pad 43 is equal to the size of the end of the nut portion 41 and the bottom wall of the inner fastener 3 .

[0021] As a further configuration of the above solution, the inner diameter of the nut groove 33 is matched with the size of the nut portion 41 of the anti-theft screw 4 .

[0022] By adopting the above scheme, in the further setting of the sealing device of this embodiment, not only a bolt member with an anti-theft nut structure design is adopted, but also a pad 43 made of plastic material is arranged between the nut portion 41 of the anti-theft screw 4 and the inner fastener 3, and the nut portion 41 of the anti-theft screw 4 is matched with the inner diameter of the nut groove 33. When the device of this embodiment is used, the nut portion 41 and the nut groove 33 are relatively fitted, and the pad 43 abuts against the end of the nut portion 41. The cooperation of the two can reduce and avoid the vibration transmitted by the vehicle during the driving of the vehicle, and avoid the problem of loosening of the anti-theft screw 4 due to vibration; in addition, the pad 43 can fill the excess part of the inner cavity of the cap 2 and the inner fastener 3, so that when a screwdriver and a needle-type tool are used for destructive disassembly, the tool is not easy to penetrate from the end of the cap 2, and after penetration, it cannot directly contact the anti-theft screw 4, further improving the anti-theft and anti-disassembly effects.

[0023] As a further configuration of the above solution, the inner diameter of the base 1 is larger than the diameter of the cap 2 , and the cap 2 is sleeved on the outer side of the inverted portion 32 and is located in the inner cavity 11 of the base 1 .

[0024] Embodiment 1: The scheme of this embodiment is as follows Figure 1-3 As shown, the inner diameter of the base 1 is larger than the cap 2. After the cap 2 is buckled with the folded portion 32, the side wall of the base 1 is still wrapped around the outside of the cap 2 to form protection, which has a stronger anti-disassembly effect and better sealing.

[0025] As a further configuration of the above solution, the folded portion 32 of the inner fastener 3 is located outside the base 1 , and the cover cap 2 is sleeved and buckled outside the folded portion 32 .

[0026] Example 2: Figure 4 As shown, in the present embodiment, the size of the base 1 is larger than the main body of the inner fastener 3 and smaller than the inverted portion 32. After the inner fastener 3 is connected to the base 1, the side wall of the base 1 is between the inverted portion 32 and the main body of the inner fastener 3. When the cap 2 is buckled, the cap 2 is wrapped around the outside of the above two, and is also fitted and prevented from falling off with the inverted portion 32. This structure is slightly different from that of Example 1. When the basic anti-disassembly principle is the same, relative to Example 1, the cap 2 that is movable relative to the base 1 is wrapped around the outside of the component, which can avoid to a certain extent the problem of the base 1 being twisted by external force, thereby causing it to rotate, and driving the internal anti-theft screws 4 to rotate and become loose.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the present invention and its equivalent technology, the present invention is also intended to include these modifications and variations.
