Embodiment 1

[0031] Such as figure 1 As shown, the car anti-counterfeit and anti-theft license plate and its fastening integrated device provided in this embodiment are composed of a plastic license plate body 1, an electronic anti-counterfeit mark 4, bolts 5, nuts 14, gaskets 15 and sliders 13.

[0032] Among them, the plastic license plate body 1 in this embodiment is made of a polymer resin / inorganic particle blend material that is sensitive to gaps, that is, 200 g of calcium carbonate and 1 kg of acrylonitrile-butadiene-styrene copolymer are mixed evenly , and then put it into a 200°C twin-screw extruder to extrude and granulate; and press the pellets and electronic barcode 4 at 210°C figure 2 The position shown is molded into a plastic license plate body, wherein each mounting hole 2 is provided with 4 wedge-shaped notches 3 at an angle of 30°. Each mounting hole 2 is matched with a bolt 5 , and each bolt 5 is composed of a bolt head 6 , a slider mounting section, a fastening sectio...

Embodiment 2

[0034] Such as figure 1 As shown, the automobile anti-counterfeit and anti-theft license plate and its fastening integrated device provided in this embodiment are also composed of a plastic license plate body 1, an electronic anti-counterfeit mark 4, a bolt 5, a nut 14, a gasket 15 and a slider 13.

[0035] The difference from Example 1 is that the plastic license plate body 1 in this example is made of 300g of talc powder and 1kg of polypropylene, mixed evenly, and then put into a twin-screw extruder at 180°C to extrude and pelletize, and the pellets Press with electronic chip 4 at 190°C figure 2 The placement position shown is molded into a plastic license plate body, wherein there are 8 wedge-shaped notches 3 on the sides of each mounting hole 2, and the angle between the notches is 60°; slider 13 is evenly installed in each mounting hole of this embodiment. slider. And the structural shape, installation position of all the other parts are because of identical with embod...

Embodiment 3

[0037] Such as figure 1 As shown, the automobile anti-counterfeit and anti-theft license plate and its fastening integrated device provided in this embodiment are also composed of a plastic license plate body 1, an electronic anti-counterfeit mark 4, a bolt 5, a nut 14, a gasket 15 and a slider 13.

[0038] The difference from Example 1 is that the plastic license plate body 1 in this example is made of 10 g of montmorillonite and 1 kg of polyoxymethylene, mixed uniformly, and then put into a twin-screw extruder at 180 ° C to extrude and pelletize, and the pellets Material and electronic magnetic strip 4 press at 190°C figure 2 The placement position shown is molded into a plastic license plate body, wherein each mounting hole 2 is provided with 2 wedge-shaped notches 3, and the angle between the notches is 20°; slider 13 is provided with two sliders in each mounting hole in this embodiment. piece. And the structural shape, installation position of all the other parts are b...

Abstract

The invention discloses an anti-fake and anti-theft number plate for a vehicle and an integral tightening device thereof, composed of a plastic number plate body, an electronic anti-fake mark, a bolt, a nut, a pad and a slide block, wherein the plastic number plate body is made of a material sensitive to notches, and a wedge-shaped notch is arranged at the side of a mounting hole of the plastic number plate body; the electronic anti-fake mark is arranged in the plastic number plate body; the bolt is formed by sequentially connecting a bolt head, a slide block mounting section, a tightening section and a bolt rod to a whole; the pear-shaped slide block is mounted in the space formed by the slide block mounting section and the wedge-shaped notch at the side of the mounting hole of the plastic number plate body; the bolt rod is composed of a backstop section and a smooth section; backstop teeth are arranged on the rod surface of the backstop section; the smooth section is a contracting section which gradually changes to the end; and a cross-shaped gap is arranged along the axial direction of the whole bolt rod. After the device is fixed on a vehicle body, the number plate cannot be stolen through normal assembly, and the number plate which is abnormally disassembled may lose use value because of the damage of the number plate; and in addition, the anti-fake and anti-theft functions can be effectively fulfilled because of the electronic anti-fake mark.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle license plates and license plate fastening devices, and in particular relates to an automobile license plate and a license plate fastening integrated device with anti-counterfeiting and anti-theft functions. Background technique [0002] As a modern means of transportation, motor vehicles play a very important role in people's lives. It can be said that people have entered the era of cars. [0003] As we all know, every motor vehicle, especially a car, must apply for and hang a motor vehicle license plate before going on the road. At present, the motor vehicle number plate is uniformly produced by the vehicle management department. It uses a machine to stamp the serial number of the ticket on a rectangular metal sheet, and then processes it through painting and other techniques. After the car owner gets the license plate, he usually fixes it to the front and rear of the vehicle with screws....
