Embodiment
The utility model is described further with reference to the accompanying drawings and examples.
Reference picture 2 and Fig. 3, this is included using the double locking positions door and window locking device of aluminum alloy driving bar：Aluminum alloy driving bar 1,
Two tapered ends 2,3, and the T-connecting piece 4 being made up of dead man 41 and dead man seat 42, described two tapered ends 2,3 are installed on described
The both ends of drive link 1, the middle part of the drive link 1 be provided for fixing two connecting holes 11 and 12 of the dead man seat 42, with
And the pilot hole 13 for supplying the dead man 41 to pass through.The locking device also includes two self-clinching nuts 7,8, the thickness of the self-clinching nut
Degree is more than the thickness of the drive link, described two connecting holes 11,12 correspondences of described two self-clinching nuts 7,8 and drive link 1
Riveting, two screw rods 5,6 coordinate with described two self-clinching nuts 7,8 is fixed on the dead man seat 42 in the drive link 1
Portion, so as to which dead man 41 to be fixedly installed in the middle part of drive link 1.
