Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiments of the present invention are described in detail so that advantages of the present invention and
Feature can be easier to be readily appreciated by one skilled in the art, thus makes protection scope of the present invention apparent
Clear and definite defines.
The advantage for the safe hinge of antitheft door of the present invention is: hinge member is strong, and reliability is high, no
The most destroyed, make antitheft door the most reliable.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of safe hinge for antitheft door, including one first connecting plate
1 and one second connecting plate 2, this first connecting plate 1 is provided with one first screw connection 11, this is second years old
One second screw connection 21 it is provided with, this first screw connection 11 and this second spiral on connecting plate 2
Connecting portion 21 is coil spring structure, and the internal diameter of this first screw connection 11 is connected with this second spiral
The external diameter in portion 21 is equal, and the inner side of this first screw connection 11 is provided with a connection projection 12, and this is second years old
The outside of screw connection 21 is provided with a connecting groove 22, and this connection projection 12 is stuck in this connecting groove 22
In.Owing to this first screw connection 11 and the second screw connection 21 connect together, joint face
Long-pending relatively big, the most extremely reliable, it is difficult to be destroyed, is highly adapted for use on antitheft door.
As in figure 2 it is shown, the cross section of this connection projection 12 and this connecting groove 22 is circular.This structure
Make this first screw connection 11 more be difficult to be separated with this second connecting portion 21, improve this further
Reliability for the safe hinge of antitheft door.
It is only more than the mentality of designing of the some embodiments of the present invention, in the case of system allows, this
Invention can expand to the most external more functional module, thus extends its function to greatest extent.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited to
This, any change expected without creative work or replacement, all should contain in protection scope of the present invention
Within.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims are limited.
