Embodiment
The preferred embodiments of the present invention are described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly defined so as to be made to protection scope of the present invention.
The present invention the safe hinge for antitheft door the advantages of be：With interconnection connecting hole together, connection
The part such as post and connection annulus, criminal is difficult to insert ripping bar in the gap between two hinges, therefore is not easy to be broken
Bad, 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 shown in figure 3, the side of first hinge 1 is provided with a connecting pole 11 arranged vertically, set on the face of cylinder of the connecting pole 11
A circular groove 111 is equipped with, a connecting hole 12, the circular section of the circular groove 111 are provided with first hinge 1
Diameter is equal with the diameter of the connecting hole 12 and inscribe is arranged；As shown in Figure 1, Figure 2, Figure 4 shows, the side of second hinge 2 is set
A connection annulus 21 is equipped with, the diameter of the cross section of the connection annulus 21 is equal with the diameter of the connecting hole 12, the connection annulus
21 pass through the connecting hole 12 and are mutually slidably connected with the connecting hole 12, and the inner side of the connection annulus 21 is caught in the circular groove
It is slidably connected in 111 and with the circular groove 111.Because the connection annulus 21 and the connecting hole 12 and the connecting pole 11 intersect
Link together, first hinge 1 and second hinge 2 can not be opened without violence damage；Due to the connection annulus 21
Cross-sectional diameter and the connecting hole 12 diameter and the circular groove 111 circular section diameter it is equal, illegal point
Son is more difficult to insert ripping bar between the first hinge 1 and the contact surface of the second hinge 2, therefore this safe hinge for antitheft door
Also it is more difficult to be pried open by ripping bar, therefore safety coefficient is higher；In addition, the contact area of first hinge 1 and second hinge 2 compared with
Small, easily by good lubrication, therefore resistance during rotation is also smaller.
As shown in figure 3, be respectively arranged with a ball groove 112 on the upper and lower end face of the connecting pole 11, as shown in figure 4, this second
The upper and lower ends of the side of hinge 2 are respectively arranged with a bulbous protrusion 22, and the bulbous protrusion 22 is arranged in the connection annulus 21
It is located on central shaft and respectively the both sides up and down of the connection annulus 21, as shown in Figure 1, Figure 2, Figure 4 shows, the diameter of the bulbous protrusion 22
Equal with the spherical diameter of the ball groove 112, the bulbous protrusion 22 is caught in the ball groove 112 and is slidably connected with the ball groove 112.If
Ball putting groove 112 and the bulbous protrusion 22 this sliding connection structure can improve the stabilization of the safe hinge for being used for antitheft door
Property, while further increase ripping bar contacts the contact surface of the connection annulus 21 and the circular groove 111, makes this for antitheft
The safe hinge of door is more difficult to be destroyed, and further improves its safety coefficient.
It is only the mentality of designing of some embodiments of the present invention above, in the case where system allows, the present invention can
To expand to while external more functional modules, so as to extend its function to greatest extent.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
The change or replacement expected without creative work, it should all be included within the scope of the present invention.Therefore, it is of the invention
Protection domain should be determined by the scope of protection defined in the claims.
