Abstract

A multi-pin hinge is composed of a fixed chain plate and a mavable chain plate. A conventional single-shaft type hinge fixes an opening direction of a door after being mounted, the opening direction only is an inward or an outward direction, thereby both use and storage of the hinge are not convenient. The multi-pin hinge is able to open the door inward and outward, especially, when the door has a flange, a concealed hinge is used, but even if a hinge with a C shape section is used, the door can opened only in 90 degrees, and traffic is affected when the door is opened constantly. The multi-pin hinge can open the door in 180 degrees to adhibit the door on a wall, thereby, even if the door is opened constantly the traffic would not be affected. The multi-pin hinge is very useful.

Description

Multi-axis hinge

The utility model relates to a kind of multi-axis hinge, and it is made of the fixedly carrier bar and the carrier bar that moves about, and it has a plurality of center of rotation, make door leaf can in open and can external-open, when particularly door leaf has the limit,, make the door leaf on limit also can open wide 180 ° because the carrier bar that moves about can be lifted away from original position to door leaf.

Present most of hinge all is a single axle, it has only a center of rotation, has to press the axle center rotation of single shaft hinge after door leaf is installed, cause can only in open or can only external-open, this product of picture security door, because door leaf has the limit, general hinge is not opened door, so just carrier bar is made the C tee section, but it can only reach 90 ° to door leaf, in public corridor, door leaf just can not often leave, otherwise can influence traffic.Door leaf that can only unidirectional rotation is wanted stock buildup undoubtedly for manufactory and dealer, the user adopts and also will make clear and could select, and has inconvenience.

The purpose of this utility model be exactly to provide a kind of can in open and the hinge of the required usefulness of door leaf that can external-open, and it can make door leaf open wide 180 °, and wants simple cheap.

The purpose of this utility model is achieved in that multi-axis hinge is by fixedly the carrier bar and the carrier bar that moves about constitute.Fixedly carrier bar is fixed on doorframe and the door leaf, goes to connect with the carrier bar that moves about therebetween.Hinge is with regard to many center of rotation like this, when opening in the door leaf around this axle center rotation, during the door leaf external-open just around other axle center rotation.Because the carrier bar of moving about has been arranged, can be lifted away from original position to door leaf, so just make the door leaf on limit also can open wide 180 °.

Owing to adopt such scheme, can make door leaf can in open and can external-open, and make the door leaf on limit also can open wide 180 °.

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is the relevant transverse cross-sectional view that existing security door adopts built-in hinge.

Fig. 2 is the relevant transverse cross-sectional view that door leaf adopts biaxial hinge of the present utility model.

Fig. 3 is the relevant transverse cross-sectional view that door leaf adopts triaxial hinge of the present utility model.

The fixedly carrier bar (4) of the fixedly carrier bar (2) of doorframe among the figure (1), door leaf, door leaf (3), doorframe, the carrier bar first of moving about (5), the carrier bar second of moving about (6).

Shown that in Fig. 1 existing security door adopts the situation of built-in hinge.Fig. 1 (a) has shown that the door limit of door leaf (3) has covered crack between a door and its frame and built-in hinge.Fig. 1 (b) has shown that the fixedly carrier bar (2) of door leaf can only rotate up and has opened the door that the influence of face and Yin Menbian can not have been opened greatly again, and the normal meeting of door leaf (3) influences traffic.

In Fig. 2, shown the situation that adopts biaxial hinge.Be connected with the carrier bar that moves about (5) between the fixedly carrier bar (2) that has shown door leaf among Fig. 2 (a) and the fixedly carrier bar (4) of doorframe.Fig. 2 (b) has shown door leaf (3) when upwards opening, and the fixedly carrier bar (2) of door leaf drives the axle center rotation that the carrier bar (5) that moves about centers on the fixedly carrier bar (4) of doorframe, can reach 180 ° to door leaf (3).Fig. 2 (c) has shown that door leaf (3) leaves downwards, and door leaf (3) revolves round the axle center of the carrier bar (2) of door leaf.Also can reach 180 ° to door leaf (3).

In Fig. 3, shown the situation that adopts triaxial hinge.Shown among Fig. 3 (a) that band edge door leaf (3) has covered triaxial hinge.Fig. 3 (b) has shown that door leaf (3) is when upwards leaving, door leaf fixedly carrier bar (2) drives the carrier bar second (6) of moving about, the carrier bar second of moving about (6) drives the carrier bar first (5) of moving about again door leaf (3) is lifted away from original position, the carrier bar second of moving about (6) is laterally passed the fixedly carrier bar (2) of door leaf left, so door leaf (3) opens wide 180 °.The imaginary line of Fig. 3 (b) below has shown door leaf (3) when opening downwards, and the fixedly carrier bar (2) of door leaf drives the carrier bar second (6) of moving about and goes to rotate around the axle center of the carrier bar first (5) of moving about, and also door leaf (3) is reached 180 °.

In sum, because the carrier bar of moving about has been arranged, make hinge that a plurality of center of rotation be arranged, make door leaf can in open and can external-open, and, have the side door fan also can open wide 180 ° because the carrier bar that moves about is lifted away from original position to door leaf.

Claims

1, a kind of multi-axis hinge is characterized in that: multi-axis hinge is made of the fixedly carrier bar and the carrier bar that moves about, and fixedly carrier bar is fixed on doorframe and the door leaf, goes to connect with the carrier bar that moves about therebetween.

2, according to the multi-axis hinge of claim 1, it is characterized in that: multi-axis hinge has a plurality of center of rotation, make door leaf can in open and can external-open.

3, according to the multi-axis hinge of claim 1, it is characterized in that: it also can be a plurality of that the carrier bar that moves about of multi-axis hinge can be 1, and the carrier bar that moves about can make door leaf be lifted away from original position, makes the door leaf on limit also can open wide 180 °.
