Specific implementation mode
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
As shown in fig. 1~fig. 5, the present invention provides a kind of car door emergency unlocking device, include mainly seizing wire 05,
The upper end of deformed compression spring 07, the seizing wire 05 is fixedly connected by screw 1 with car door latch hook 11, the sedan-chair
Compartment door lock hook 11 is linked by latch hook Assembly of pin 04 and mounting plate 1, and the mounting plate 1 is fixed with left side car door 01
Connection, 05 lower end of the seizing wire are fixedly connected by bolt assembly 06 with 07 top of deformed compression spring, the abnormity pressure
07 lower part of contracting spring is located in the groove 0801 of positioning seat 08, and 07 top of the deformed compression spring is equipped with arc section 0702, and
By arc section 0702 and 0701 transition integrally connected of straightway, the straightway 0701 is out of, positioning seat 08 centre bore 0803
It passes through, with 08 pivot bush unit of positioning seat, 0701 lower end of the straightway is fixedly connected by screw 2 12 with positioning plate 2 10, institute
It states positioning seat 08 to be socketed with positioning plate 1, the positioning plate 1 is fixed with left side car door 01 respectively with positioning plate 2 10 to be connected
It connects.
The bolt assembly 06 includes bolt 17, and the bolt 17 is socketed arc section 0702, plain cushion 2 16, finer wire successively
