Abstract

The utility model comprises a hinge which has three rotary points or five rotary points. The first rotary point is connected with the hinge base of the door leaf. The third rotary point is connected with the hinge base of the door frame. The rotary axle of the first rotary point is movably connected with a guiding post, and a guiding sleeve which is matched with the guiding post is fixedly connected with the door frame. The left side and the right side of the door frame are provided with flutes. Both sides of the door leaf are respectively inserted into the flute in the closed state, and the door leaf can be freely opened inwards and outwards. The utility model is stable and free to be opened and closed. The usage is convenient, the door is not limited by the space and the region, the machinery clamp can be saved, and the inventory is reduced.

Description

External-open security door in embedded

The utility model relates to a kind of security door, especially can in open and security door that can external-open.

Existing security door or can only in open or can only external-open, use inconvenient, and waste frock clamp, stock buildup.

But the purpose of this utility model is to make in the same shelves Men Jike to open and external-open, uses conveniently, and saves frock clamp and minimizing stock.

The purpose of this utility model is to realize like this, hinge design is become three turning points or five turning point structures, first turning point is connected on the door leaf hinge seat, the 3rd turning point and the 5th turning point are connected on the hinge seat of doorframe, flexibly connect the vertical lead of this rotating shaft of a lead in the rotating shaft of first turning point, the fairlead of Pei Heing is fixed on the doorframe with it, and groove is established in the doorframe left and right sides, and door leaf descends both sides all to embed in the groove in off position.

The utility model because many turning points hinge is provided with the guiding device that is made of lead and fairlead, thereby can not only make door leaf debouch groove about doorframe under the state of opening and closing, and open and external-open in realizing arbitrarily freely.

It below is the embodiment accompanying drawing.

Three turning point hinge arrangements signal of the present utility model under Fig. 1 door leaf closed condition;

The situation of Fig. 2 the utility model under the door leaf opening;

Fig. 3 five turning point hinge arrangements signal of the present utility model.

Now reaching accompanying drawing in conjunction with the embodiments further specifies.

As shown in Figure 1, after closing door leaf, door leaf, embed in the groove of doorframe, in the notch of door leaf side, be fixed with on the hinge seat, loose-leaf in first turning point be connected on the hinge seat, loose-leaf and hinge seat are provided with parallel with the door leaf face and the consistent adjusting bolt with the door leaf length direction, it is vertical with rotating shaft with its length direction to connect a lead by kink in the rotating shaft of first turning point, the fairlead that cooperates with lead and being fixed on the doorframe (11), the 3rd turning point is connected on the hinge seat (7) on the doorframe, one end of first extension spring (12) is connected in the rotating shaft of second turning point, the other end is fixed on the doorframe (11), and second end that connects spring (9) is fixed in the rotating shaft that is positioned at first turning point on the door leaf, and the other end is fixed on the extension spring fixed head on the doorframe.

When door was opened, door leaf was towards the translation of hinge side, then need only be by the opening direction certain angle that tilts, and door leaf will eject the doorframe groove rapidly under spring action, one push away gently, and door promptly is in complete opening state (as shown in Figure 2).

Only the 4th turning point (5 ') and the 5th turning point (6 ') have been set up in the structure shown in Figure 3 at the opposite side of the axis of guide, the 4th turning point (5 ') and second turning point (5), the 5th turning point (6 ') and the 3rd turning point (6) respectively with in lead (8) symmetry, all the other same Fig. 1 no longer continue and state.

Hinge second turning point and the 4th turning point respectively have a synchronizing shaft about in the utility model, and hinge is coordinated freely when opening with assurance door leaf pass.
