Abstract

The utility model relates to an automatic bolt for a double casement door, which is mainly composed of a top beam bracket (2) with a movable shaft (1) and a bottom seat bracket (6) with a movable shaft (5). The movable shaft of the top beam bracket is fixed with a left bolt (3) and a right bolt (4) which are arranged in a cross way, and the movable shaft of the bottom seat bracket is fixed with a left bolt (7), a right bolt (8) and a stable block (9) which are arranged in a cross way. When the utility model is used, the double casement door has ideal theft-proof safety effect by the help of the match and limitation between the top beam, the left and right bolts in the bottom seat and a door lock.

Description

The double door automatic pinning

The utility model relates to a kind of automatic pinning that door and window is closed that is exclusively used in.

Existing the closing of double door that can open simultaneously generally is to load onto simple and easy latch on Yishanmen, load onto lock between the Men Yumen simultaneously, during use, to there be the door of latch to shut earlier, in the jack with jack on the latch insertion door beam and base ground, then other Yishanmen is shut and locked, though convenience simple in structure, but safety is relatively poor, and more and more the incompatibility modern room is to the needs of security personnel's condition.

The purpose of this utility model provides a kind of safe and practical novel latch.

This reality has the novel double door automatic pinning that is, mainly constitute by the last roof beam structure (2) of band movable axis (1) and the pony sill (6) of band movable axis (5), be fixed with left latch (3) arranged in a crossed manner and right pin (4) on it on the movable axis of roof beam structure, be fixed with left latch (7) arranged in a crossed manner on the movable axis of pony sill, right pin (8) and stable piece (9).

Accompanying drawing has provided structural representation of the present utility model

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a double door closed condition schematic diagram;

Fig. 3 is a double door opening schematic diagram.

Below in conjunction with embodiment the utility model is further described:

To go up roof beam structure (2) and be fixed in doorframe upper beam middle part, pony sill (6) is imbedded and the vertical corresponding ground of last roof beam structure.When door (10) when closing, right pin (4) in the last roof beam structure on the movable axis (1) is pressed on the cross section, top of right door, right pin (8) on the movable axis (5) in the pony sill also withstands on the bottom transverse section of right door, be the level of state, left latch (3) on movable axis this moment (1) and the corresponding outer of being close to left-hand door of left latch (7) on the movable axis (5), after locking between the left and right door, because of put the beams in place, cooperatively interacting and restricting between left and right latch and the door lock in the base, left and right door can not be opened, (as shown in Figure 2); When needs open the door, earlier the lock between the left and right door is opened, can draw back right door this moment, in right Men Lakai, the right pin on the last roof beam structure (4) gravitate makes corresponding being the level of state of left latch (3) on the same movable axis in vertical state, right pin (8) on the while pony sill is stablized piece gravity when You Men draws back effect, also in vertical state, make that left latch (7) is also corresponding to be the level of state, this moment, left-hand door also can be opened freely.

The utility model is reasonable in design, and is simple in structure, cooperatively interacts between left and right latch and the door lock and restricts, and makes double door have desirable theft-proof insurance result, and simultaneously, it is convenient to open, and is applicable on the double door of various occasions and uses.

Claims

1, a kind of double door automatic pinning, constitute by the last roof beam structure (2) of band movable axis (1) and the pony sill (6) of band movable axis (5), it is characterized in that being fixed with left latch (3) arranged in a crossed manner and right pin (4) on the movable axis (1) of roof beam structure, be fixed with left latch (7) arranged in a crossed manner and right pin (8) on the movable axis of pony sill (5).

2,, it is characterized in that also being fixed with stable piece (9) on the movable axis (5) of described pony sill by the described double door automatic pinning of claim 1.
