The invention discloses a multifunctional anti-theft valve of an automobile fuel tank, which relates to the technical field of automobile fuel tank theft prevention, and comprises a refueling valve body, a mechanical lock mechanism for locking a sealing cover, an alarm mechanism and a plugging assembly mechanism, and the top of the refueling valve body is provided with the sealing cover. The sealing cover is locked on the refueling valve body through the mechanical lock structure to prevent burglary, when the mechanical lock structure is normally unlocked to open the sealing cover for refueling, a rotary lock cylinder of the mechanical lock structure is unlocked and rotated, so that an arranged clamping block is driven to move to clamp a plugging block in the refueling valve body, and the refueling valve body is conveniently driven to be opened together when the cover is opened; when the sealing cover is forcibly prized open and is not normally unlocked, the clamping block connected with the sealing cover cannot complete the action of clamping and butting with the plugging block, at the moment, the plugging block cannot be taken out when the sealing cover is opened and detached, and notches in the two sides of the plugging block are sealed by elastic plugging pieces, so that the plugging block cannot be taken out by finding a grabbing point from an external appliance; therefore, the anti-theft effect is ensured.
本发明公开了一种汽车油箱的多功能防盗阀,涉及汽车油箱防盗技术领域,包括加油阀体,所述加油阀体的顶部配设有封闭盖,还包括用于锁住封闭盖的机械锁机构、警报机构和封堵装配机构。本发明封闭盖通过机械锁结构锁在加油阀体上进行防盗,正常解锁机械锁结构打开封闭盖加油时,机械锁结构的旋转锁芯解锁旋转,从而带动设置的夹块运动夹住加油阀体内的封堵块,方便在开盖时带动加油阀体一起打开,而当封闭盖被强行撬开,未进行正常解锁时,封闭盖连接的夹块则无法完成与封堵块夹持对接的动作,此时打开拆下封闭盖无法带出封堵块,且封堵块两侧缺口依靠弹性封堵件封住,导致无法从外部使用器具找到抓取点取出封堵块,从而保证防盗效果。
