The utility model is characterized in that the outer side of the rotating lock head (2) is provided with a master lock cover (5), a main rotating shaft (6) is fixed between the master lock base (4) and the master lock cover (5), and the rotating lock head (2) which rotates around the main rotating shaft (6) is installed between the master lock base (4) and the master lock cover (5).

Description

The door and window lock

The utility model relates to a kind of lockset that is applied on door or the window.

At present a kind of door and window commonly used lock comprises main lock body and snap close two parts, main lock body and snap close are separately fixed at two fans and push or push away on the window, when door or window are in the closed position, thereby rotating rotational lock head on the main lock body makes it to enter in the lock hole of snap close and makes door or sash lock fix on fastening position, wherein main lock body mainly is made of main lock and rotational lock head, because rotational lock head is installed on the main lock and directly as the part of main lock body external surface, rotational lock head is caused main lock body durable inadequately by external world's collision easily in the use.

The purpose of this utility model provides a kind of more durable door and window lock.

To achieve these goals, technical solution of the present utility model is such: the door and window lock comprises main lock body and snap close two parts, wherein main lock body is except comprising main lock and rotational lock head, the outside at rotational lock head also is provided with main locking closure, be fixed with main shaft between main lock and the main locking closure, rotational lock head is installed between main lock and the main locking closure and around main shaft and rotates.

Because in the above-mentioned technical solution, main locking closure also is stamped in the outside of rotational lock head, has avoided rotational lock head directly to be collided, thereby makes main lock body more durable, therefore this door and window is phase-locked to more durable.

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

Fig. 1 is the Facad structure figure of main lock body.

Fig. 2 is the lateral plan of main lock body.

Fig. 3 is the Facad structure figure of snap close.

Fig. 4 is the lateral plan of snap close.

Fig. 5 is the A-A sectional view of Fig. 1.(dotted line is represented the snap close position)

Fig. 6 is the front view of rotational lock head.

Fig. 7 is the lateral plan of rotational lock head.

Fig. 8 is the front view of main lock.

Fig. 9 is the lateral plan of main lock.

Figure 10 is the front view of spring bearer plate.

Figure 11 is the B-B sectional view of Figure 10.

Wherein: 1, snap close; 2, rotational lock head; 3, lock hole; 4, main lock; 5, main locking closure; 6, main shaft; 7, positioning through hole; 8, positioning ball; 9, location pit; 10, spring bearer plate.

As shown in the figure, the door and window lock comprises main lock body and snap close 1 two parts, main lock body mainly is made of main lock 4, main locking closure 5, main shaft 6, rotational lock head 2, is fixed with main shaft 6 between main lock 4 and the main locking closure 5, and rotational lock head 2 is installed between main lock 4 and the main locking closure 5 and around main shaft 6 and rotates.

In order to make rotational lock head 2 can stably remain on a certain operating position, rotational lock head 2 of the present utility model is provided with positioning through hole 7, positioning ball 8 is housed in the positioning through hole 7, main lock 4 is provided with location pit 9 towards the one side of rotational lock head 2, the outside of rotational lock head 2 also is provided with spring bearer plate 10, rotational lock head 2 together with positioning ball 8 by main lock 4 and spring bearer plate 10 from two side compressions.As Fig. 5, Fig. 6, shown in Figure 8, the rotational lock head 2 of main lock body is provided with two positioning through hole 7, the center of rotation of the center of these two positioning through hole 7 and rotational lock head 2 in a straight line, and equidistantly be located at the both sides of rotation lock head pivot point, main lock 4 is provided with 9, four location of pits, four location pit 9 towards the one side of rotational lock head 2 and is distributed on the circumference at two positioning through hole 7 places.

When main lock body and snap close 1 are close together and lock, rotational lock head 2 enters in the lock hole 3 of snap close 1 main lock body and snap close 1 can not be moved mutually, at this moment the positioning ball 8 in the positioning through hole 7 of rotational lock head 2 firmly drops in the location pit 9 of main lock 4, when the rotational lock head 2 with the main lock body of Fig. 1 lock-out state rotates counterclockwise, rotational lock head 2 can drive positioning ball 8 and extrude in the pit 9 of location, rotational lock head 2 rotates about 90 degree back positioning balls 8 and can fall in other two location pits 9 of main lock 4, and being stabilized in this position, at this moment main lock body and snap close 1 can move freely mutually.
