Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses special solid sealing device of motor vehicle license plate, refer to fig. 1, special solid sealing device of motor vehicle license plate includes base 1, jump ring 2, bolt 3 and buckle closure 4, and jump ring 2 clamps in the lateral wall inslot of base 1, and wherein, base 1 and buckle closure 4 all adopt cold heading technology to process, reduce the processing requirement, and the exposed portion polishing finish is high. The bolt 3 passes through the base 1, the license plate and the license plate fixing seat in sequence and fixes the license plate on the vehicle. After the license plate is fixedly installed, the buckle cover 4 is buckled outside the base 1 and is in clamping fit with the clamp spring 2 outside the base 1, and the buckle cover 4 completely covers the base 1 and is sealed and fixed.
