Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of safe hinge for security door, comprise one first junction plate and one second junction plate, the first described junction plate is provided with one first screw connection, the second described junction plate is provided with one second screw connection, the first described screw connection and the second described screw connection are coil spring structure, the internal diameter of the first described screw connection is equal with the external diameter of the second described screw connection, the inner side of the first described screw connection is provided with a connection projection, the arranged outside of the second described screw connection has a connecting groove, described connection projection is stuck in described connecting groove.
As the utility model preferred embodiment, described connection projection and the cross section of described connecting groove are circular.
The advantage of the safe hinge for security door of the present utility model is: hinge member is strong, and reliability is high, is not easily destroyed, and makes security door comparatively reliable.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of the safe hinge for security door of the present utility model;
Fig. 2 is the front view of the safe hinge for security door in Fig. 1;
Fig. 3 is the top view of the safe hinge for security door in Fig. 1;
Wherein:
1, the first junction plate; 11, the first screw connection; 12, projection is connected;
2, the second junction plate; 21, the second screw connection; 22, connecting groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
The advantage of the safe hinge for security door of the present utility model is: hinge member is strong, and reliability is high, is not easily destroyed, and makes security door comparatively reliable.
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of safe hinge for security door, comprise one first junction plate 1 and one second junction plate 2, this first junction plate 1 is provided with one first screw connection 11, this second junction plate 2 is provided with one second screw connection 21, this first screw connection 11 and this second screw connection 21 are coil spring structure, the internal diameter of this first screw connection 11 is equal with the external diameter of this second screw connection 21, the inner side of this first screw connection 11 is provided with a connection projection 12, the arranged outside of this second screw connection 21 has a connecting groove 22, this connection projection 12 is stuck in this connecting groove 22.Because this first screw connection 11 and the second screw connection 21 connect together, connection area is comparatively large, therefore very reliable, is not easily destroyed, is very suitable for being used on security door.
As shown in Figure 2, the cross section of this connection projection 12 and this connecting groove 22 is circular.This structure makes this first screw connection 11 more not easily be separated with this second screw connection 21, improves the reliability of this safe hinge for security door further.
Below be only the mentality of designing of some embodiments of the present utility model, when system allows, the utility model can expand to external more functional module simultaneously, thus expands its function to greatest extent.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
