The invention relates to an anti-theft fixing and sealing device for a motor vehicle license plate. A bolt component is of a split structure (as shown in the figure 2), and the bolt component forms a whole after being assembled and cannot be separated again. Through the special structural design, the bolt component transmits power in one direction and can only be screwed in but not screwed out, and the bolt body 4 is wrapped and protected by the anti-theft cap 6, so that the anti-disassembly and anti-theft functions are very strong; and meanwhile, a good maintenance function is achieved, the situation that threads of the nut of the vehicle body are possibly damaged when the fixing and sealing device is disassembled legally can be effectively avoided, and the anti-theft function and the maintenance function are perfectly combined and do not affect each other.
本发明是一种机动车辆号牌防盗固封装置。螺栓部件采用分体式结构(如附图2),螺栓组件装配后形成一个整体不能再次分离。通过特殊的结构设计,螺栓部件单向传递动力,只能旋进不能旋出,且螺栓本体4被防盗帽6包裹保护,具备很强的防拆防盗功能;同时也具备良好的维护功能,可以有效避免合法拆卸固封装置时可能造成对车辆本体螺母螺纹的损坏,使防盗功能和维护功能都达到完美结合而不相互影响。
