Abstract

The utility model relates to a concealed hinge used for anti-theft doors, which comprises a hinge body 1 and a hinge seat 2, wherein one end of the hinge body is connected with the hinge seat arranged in a door frame 4 through a rotating shaft 3, and the other end of the hinge body is connected with a rotating shaft 5 connected with a connecting sheet 6 for a door leaf; the connecting sheet 6 for a door leaf is connected with a door leaf 7. The utility model is characterized in that the rotating shaft 5 or the rotating shaft 3 is provided with an elastic device. When in use, the hinge of the utility model can control the precedence rotation order of the two rotating shafts. When a door is opened, the rotating shaft arranged in the door frame firstly rotates, and the rotating shaft arranged in the door leaf subsequently rotates under the action of the elastic device. When the door is closed, the rotating shaft arranged in the door leaf firstly rotates under the action of the elastic device, and the rotating shaft arranged in the door frame subsequently rotates. The hinge works reliably, can not cause seam covered edges of the door leaf to bunt to the door frame, and is suitable for the existing anti-theft doors.

Description

The security door blind hinge

Technical field:

The utility model relates to the security door blind hinge, particularly a kind of blind hinge that can 180 ° of unlatching door leafs.

Background technology:

At present, blind hinge commonly used in the security door generally can only be opened to 90 °-110 °, and can not be opened to 180 °.When security door is installed on the exterior wall plane, tend to because the reason of hinge can not bring great inconvenience for people's life Men Kaiping.Be head it off, just disclose a kind of " stealthy comprehensive door hinge " Chinese patent 02114737.X number, it is provided with two rotating shafts on hinge bodies, can make door leaf be 180 ° of unlatchings, and the door physical efficiency after the unlatching abuts in the frame side wall.But there is following defective in it, makes this hinge can not be applicable to present security door:

1, is equipped with the screening tape edge, the order that uncontrollable in use two rotating shafts of this kind hinge are successively rotated on the door leaf of existing security door; The rotating shaft of being located at when opening the door in the door leaf is rotated earlier or is rotated earlier in the rotating shaft of being located in the doorframe at closing time, all can cause door leaf screening tape edge and doorframe inconsistent, makes door be difficult to open.

2, in manufacture process, the gap of door leaf and doorframe can't be adjusted, and has brought a lot of inconvenience to production.

Summary of the invention:

For addressing the aforementioned drawbacks, the inventor proposed a kind of can 180 ° unlatching, open security door blind hinge reliable, easy for installation.It comprises: hinge bodies 1 and hinge seat 2, and hinge bodies one end links to each other with hinge seat in being located at doorframe 4 by rotating shaft 3; The other end of hinge bodies is connected with rotating shaft 5, and rotating shaft 5 is connected with door leaf brace 6, and door leaf brace 6 links to each other with door leaf 7; It is characterized in that: described rotating shaft 5 or rotating shaft 3 are provided with elastic device.Make hinge of the present utility model can control the order that two rotating shafts are successively rotated in use.When opening the door, the rotating shaft of being located in the doorframe is rotated earlier, and rotate rotating shaft back under the effect of elastic device of being located in the door leaf; At closing time, be located at rotating shaft in the door leaf and under the effect of elastic device, rotate earlier, rotate after being located at the rotating shaft in the doorframe; The hinge reliable operation can not cause door leaf screening tape edge and doorframe inconsistent, is applicable to existing security door.

At the elastic device described in the utility model preferably: be located at the spring 8 in rotating shaft 5 axle sleeves, one end of spring be positioned the door leaf brace or with parts that the door leaf brace links to each other in, the other end of spring be positioned hinge bodies or with parts that hinge bodies links to each other in.Make hinge arrangement of the present utility model simpler relatively, reliable operation.

In the utility model, described hinge bodies divide with the doorframe section of linking to each other 9 with 10, two sections hinge bodies of the door leaf section of linking to each other in the microscler adjustment hole 11 and the screw that are provided with, and be connected by securing member 12.Can adjust the crack between a door and its frame gap by adjusting the position of securing member in microscler adjustment hole.

In the utility model, described elastic device also can be located in the rotating shaft 3, and it can finish goal of the invention of the present utility model equally.

The specific embodiment:

In conjunction with Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: the security door of present embodiment comprises with blind hinge: hinge bodies 1 and hinge seat 2, and hinge bodies one end links to each other with hinge seat in being located at doorframe 4 by rotating shaft 3; The other end of hinge bodies is connected with rotating shaft 5, and rotating shaft 5 is connected with door leaf brace 6, and door leaf brace 6 links to each other with door leaf 7; Rotating shaft 5 is provided with elastic device.Elastic device comprises: be provided with spring 8 in rotating shaft 5 axle sleeves, an end of spring be positioned the door leaf brace or with parts that the door leaf brace links to each other in, the other end of spring be positioned hinge bodies or with parts that hinge bodies links to each other in.Hinge bodies divide with the doorframe section of linking to each other 9 with 10, two sections hinge bodies of the door leaf section of linking to each other in the microscler adjustment hole 11 and the screw that are provided with, and be connected by securing member 12.

The hinge of present embodiment can be controlled the order that two rotating shafts are successively rotated in use.Make and the hinge reliable operation can not cause door leaf screening tape edge and doorframe inconsistent.Because hinge bodies is divided into two sections and removable, is convenient to the manufacturing and the installation of security door, and can adjusts the crack between a door and its frame gap.Certainly hinge bodies also can be an one, though it can influence the convenience of making and installing, also can control the order that two rotating shafts are successively rotated, and finishes and opens reliable purpose.

Fig. 5, Fig. 6 have provided the utility model hinge two kinds of different structure forms in addition at rotating shaft 5 place's elastic devices.Be provided with two location hole of the spring 13 in its axle sleeve, spring inserted just can realize controlling the order that two rotating shafts are successively rotated in the locating hole.
