Groove, described connection projection is stuck in described connecting groove.Although this safe hinge for antitheft door has hinged
Parts are strong, and reliability height is not easy the advantages such as destruction, but this two spirals in the safe hinge of antitheft door are even
The portion that connects is more difficult to be fitted together so that it is production cost is higher；The area of the contact surface of two screw connection is relatively big and outside being positioned at
The inner side of the screw connection of side, it is more difficult to by good lubrication, the resistance produced when therefore rotating is relatively big, makes antitheft door be not easy out
Closing, contact area also makes it easily be worn relatively greatly.
Utility model content
This utility model mainly solves the technical problem existing for prior art, thus provides a kind of with interconnection
The parts such as connecting hole, connection post and connection annulus together, lawless person is difficult to ripping bar is inserted the seam between two hinges
In gap, being therefore not easy to be destroyed, structure is strong, the safe hinge for antitheft door that safety coefficient is higher.
This utility model solves the technical problem in the presence of prior art by following technical proposals:
A kind of safe hinge for antitheft door, including one first hinge and one second hinge, the first described hinge
Side is provided with a connection post vertically arranged, the described face of cylinder connecting post is provided with a circular groove, described
Being provided with a connecting hole on first hinge, the diameter of the circular section of described circular groove is straight with described connecting hole
Footpath is equal and inscribe is arranged；The side of the second described hinge is provided with a connection annulus, the described cross section connecting annulus
The equal diameters of diameter and described connecting hole, described connect annulus through described connecting hole and with described connecting hole
Mutually it is slidably connected, slides in the described inner side connecting annulus snaps in described circular groove and with described circular groove
It is dynamically connected.
As this utility model preferred embodiment, the described upper and lower end face connecting post is respectively arranged with a ball groove,
The two ends up and down of the side of the second described hinge are respectively arranged with a bulbous protrusion, and described bulbous protrusion is arranged in described
Connect on the central shaft of annulus and lay respectively at the described both sides up and down connecting annulus, the diameter of described bulbous protrusion and institute
The spherical diameter of the ball groove stated is equal, in described bulbous protrusion snaps in described ball groove and is slidably connected with described ball groove.
Advantage for the safe hinge of antitheft door of the present utility model is: with interconnection connecting hole together,
Connecting post and connect the parts such as annulus, lawless person is difficult to insert in the gap between two hinges ripping bar, is therefore not easy
Destroyed, structure is strong, and safety coefficient is higher.

Detailed description of the invention
Below preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature energy
It is easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
Advantage for the safe hinge of antitheft door of the present utility model is: with interconnection connecting hole together,
Connecting post and connect the parts such as annulus, lawless person is difficult to insert in the gap between two hinges ripping bar, is therefore not easy
Destroyed, structure is strong, and safety coefficient is higher.
As shown in Figure 1 and Figure 2, a kind of safe hinge for antitheft door, including one first hinge 1 and one second hinge 2,
As it is shown on figure 3, the side of this first hinge 1 is provided with a connection post 11 vertically arranged, the face of cylinder of this connection post 11 sets
It is equipped with a circular groove 111, this first hinge 1 is provided with a connecting hole 12, the circular section of this circular groove 111
The equal diameters of diameter and this connecting hole 12 and inscribe arrange；As shown in Figure 1, Figure 2, Figure 4 shows, the side of this second hinge 2 sets
It is equipped with the equal diameters of a connection annulus 21, the diameter of the cross section of this connection annulus 21 and this connecting hole 12, this connection annulus
21 through this connecting hole 12 and are mutually slidably connected with this connecting hole 12, and the inner side of this connection annulus 21 snaps in this circular groove
In 111 and it is slidably connected with this circular groove 111.Owing to this connection annulus 21 is connected post 11 intersects with this connecting hole 12 and this
Link together, make this first hinge 1 and this second hinge 2 cannot be opened without violence damage；Due to this connection annulus 21
The diameter of cross-sectional diameter and this connecting hole 12 and the equal diameters of circular section of this circular groove 111, illegal point
Son is more difficult to be inserted between the first hinge 1 and the contact surface of the second hinge 2 by ripping bar, the most this safe hinge for antitheft door
The most difficult being pried open by ripping bar, therefore safety coefficient is higher；Additionally, the contact area of this first hinge 1 and this second hinge 2 is relatively
Little, easily by good lubrication, resistance when therefore rotating is the least.
As it is shown on figure 3, be respectively arranged with a ball groove 112 on the upper and lower end face of this connection post 11, as shown in Figure 4, this is second years old
The two ends up and down of the side of hinge 2 are respectively arranged with a bulbous protrusion 22, and this bulbous protrusion 22 is arranged in this connection annulus 21
On central shaft and lay respectively at the both sides up and down of this connection annulus 21, as shown in Figure 1, Figure 2, Figure 4 shows, the diameter of this bulbous protrusion 22
Equal with the spherical diameter of this ball groove 112, in this bulbous protrusion 22 snaps in this ball groove 112 and it is slidably connected with this ball groove 112.If
Ball putting groove 112 and this this sliding connection structure of bulbous protrusion 22 can improve this stablizing of safe hinge for antitheft door
Property, increasing ripping bar the most further contacts the contact surface of this connection annulus 21 and this circular groove 111, makes this for antitheft
The safe hinge of door is more difficult to be destroyed, and improves its safety coefficient further.
It is only more than the mentality of designing of some embodiments of the present utility model, in the case of system allows, this reality
The most external more functional module can be expanded to novel, thus extend its function to greatest extent.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to
In this, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
