Abstract

A pilfer proof door with a 180degree opening comprises a door frame1, a door fan2, a lockset, a plurality of hinges3 which is used to connect the door frame and the door fan, one end of the hinge is connected to the door frame1 via a shaft4, and the other end is connected to a connection lug6 of the door fan via a shaft5, and the connection lug6 is connected to the door fan2, and the hinges are arranged on the same shaft4 which is arranged at one side of the door frame, so the hinge shafts which are arranged at one side of the door frame are the same one, therefore enabling the hinges shaft of the door frame to turn synchronously, preventing the incoordination of the hinges shaft of the door frame in the process of opening and closing, the incoordination can make the joint edge of the door fan collides with the door frame.

Description

180 ° of unlatching security doors

Technical field:

The utility model relates to a kind of security door that can 180 ° of unlatchings.

Background technology:

Security door commonly used generally can only be opened to 90 °-110 °, has brought very big inconvenience to use.Be head it off, just disclose a kind of " adopting the lid limit metal door of novel blind hinge " Chinese patent 01248766.X number, this security door can 180 ° of unlatchings, because the complex structure of hinge makes the cost of manufacture of security door increase greatly.And Chinese patent 02114737.X number also disclose a kind of " stealthy comprehensive door hinge ", and this hinge is provided with two rotating shafts.But it is in following defective:

1, generally between antitheft door leaf and doorframe adopt a plurality of hinges to link to each other, and each hinge rotating shaft makes each hinge rotating shaft of being located in the doorframe not rotate synchronously because of the different stressed differences of hinge setting height(from bottom), door leaf screening tape edge and doorframe are inconsistent when causing the open and close door.

2, be equipped with the screening tape edge on the existing security door door leaf, and the order that uncontrollable in use each hinge two rotating shaft of this kind hinge are successively rotated; 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.

Summary of the invention:

For addressing the aforementioned drawbacks, the inventor proposed a kind of can 180 ° unlatching, open reliable security door.It comprises: doorframe 1, door leaf 2, lockset and some hinges 3 that doorframe is connected with door leaf, and hinge one end links to each other with doorframe 1 by rotating shaft 4; The hinge other end is connected with door leaf brace 6 by rotating shaft 5, and door leaf brace 6 links to each other with door leaf 2.The rotating shaft 4 that described some hinges are located at doorframe one side is same rotating shaft.Because being located at the hinge rotating shaft of doorframe one side is same rotating shaft, makes that each the hinge rotating shaft in the doorframe can be rotated synchronously, each hinge rotating shaft rotation of being located at when having avoided the open and close door in the doorframe is inharmonious, makes door leaf hide tape edge and the inconsistent phenomenon of doorframe.

In the utility model, be located at door leaf shaft 5 and be provided with torsion spring 7.Can control the order that two rotating shafts of each hinge are successively rotated during 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 torsion spring of being located in the door leaf; At closing time, be located at rotating shaft in the door leaf and under the effect of torsion spring, rotate earlier, rotate after being located at the rotating shaft in the doorframe; The door leaf that each hinge two rotating shaft rotational disorder causes when having avoided the open and close door hides tape edge and the inconsistent phenomenon of doorframe.

In the utility model, the torsion spring 7 of being located at door leaf rotating shaft 5 can be provided with in the following ways: an end of torsion spring be positioned the door leaf brace or with parts that the door leaf brace links to each other in, the other end of torsion spring be positioned hinge or with parts that hinge links to each other in.Certainly as long as between door leaf brace and hinge, can produce torsion, adopt other structure also can.

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

The specific embodiment:

In conjunction with Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: it comprises the security door of present embodiment: doorframe 1, door leaf 2, lockset and some hinges 3 that doorframe is connected with door leaf, and hinge one end links to each other with doorframe 1 by rotating shaft 4; The hinge other end is connected with door leaf brace 6 by rotating shaft 5, and door leaf brace 6 links to each other with door leaf 2.The rotating shaft 4 that some hinges are located at doorframe one side is same rotating shaft.Make each the hinge rotating shaft in the doorframe to rotate synchronously.Rotating shaft 4 cross sections can be as shown in Figure 4, and it can guarantee that each hinge rotates synchronously.Adopt this type of elongated rod shape rotating shaft also to be convenient to the installation of hinge.

As Fig. 5, shown in Figure 6: be located in the axle sleeve of door leaf shaft 5 and be provided with torsion spring 7, an end of torsion spring be positioned the door leaf brace or with parts that the door leaf brace links to each other in, the other end of torsion spring be positioned hinge or with parts that hinge links to each other in.The torsion of this torsion spring can be done lessly relatively, and the rotation precedence that can satisfy two rotating shafts of guaranteeing each hinge just can.

If the rotating shaft that each hinge is located at doorframe one side is discrete rotating shaft, then the torsion of torsion spring need be done greatlyyer, with the rotation precedence of two rotating shafts of the synchronous rotation of guaranteeing to be located at each rotating shaft in the doorframe and each hinge.After adopting this structure, door leaf just is difficult to arbitrarily be positioned at desired location.

As Fig. 5, shown in Figure 6: hinge divide with the doorframe section of linking to each other with the door leaf section of linking to each other, the microscler adjustment hole 8 and the screw that are provided with in two sections hinges, and be connected by securing member.
