Abstract

The utility model relates to an omnibearing locking device for burglarproof doors or windows. The utility model is characterized in that a push rod is connected with a centre lock, a lock head or a locating sleeve is connected with the push rod, and the lock head and the locating sleeve are locked with a matched locating sleeve or a matched lock head. The lock head forms an L shape, when the centre lock is dialled to cause the push rod to operate, the locating sleeve is hooked by the lock head, and an ideal burglarproof effect is reached. The utility model not only has the advantages of simple structure, opening agility, but also when the thief pries the windows and doors in a strong force, even if the lock is deformed, and the lock head is not easy to pull out from the locating sleeve. The utility model really realizes the burglarproof goal.

Description

The comprehensive locking device of pick-proof door and window

The utility model relates to a kind of door and window locking device, the comprehensive locking device of particularly a kind of pick-proof door and window.

At present, the pick-proof door locking device of installing and using on the door and window is of a great variety, no matter is the single-point locking by center lock control by the door and window locking device that push rod drive tapered end locks, or comprehensive multi-point fastening, and its locking position is straight type tapered end, during owing to close the doors and windows, tapered end on the wing is by mechanical linkage which controls, and its straight cutting is gone in the positioning sleeve of doorframe and window frame, so when the burglar firmly prizes its door and window, tapered end is very easily taken out of because of the door and window distortion, makes its pick-proof poor-performing.

The purpose of this utility model is to provide a kind of pick-proof door and window comprehensive locking device, and it is not only simple in structure, unlatching is flexible, and the pick-proof performance is strong.

Its concrete solution is: be connected with tapered end or positioning sleeve respectively in the mechanical linkage which controls with on the push rod that center lock is connected, and, what lock with tapered end and positioning sleeve is a positioning sleeve that matches or a tapered end, and described tapered end is the L type, make that tapered end will hook positioning sleeve and reach comparatively ideal pick-proof effect when stirring center lock push rod is moved.

In addition then, the jack geomery with the corresponding positioning sleeve of tapered end is identical with tapered end insertion position.

The utility model is owing to adopt the tapered end of L type, during so close the doors and windows, tapered end can hook the positioning sleeve that is connected on wing or the door and window firmly, thereby make that this locking device is not only simple in structure, open flexibly, even and door and window is out of shape to some extent when the burglar firmly prizes its door and window, tapered end also is difficult for deviating from from positioning sleeve, really realizes the purpose of pick-proof.

In conjunction with the accompanying drawings the utility model is described in detail below by embodiment:

Fig. 1 is the user mode structural representation of embodiment 1.

Fig. 2 is the lateral view of Fig. 1.

Fig. 3 is the user mode structural representation of embodiment 2.

Embodiment 1:

Fig. 1, Fig. 2 one are installed in the locking device that door go up to use.Be arranged in the mechanical linkage which controls on the wing (6), one end of top push rod (2), bottom push rod (7) is connected with center lock (5), the other end is connected with an ordinary straight type tapered end (1) respectively, the middle part of top and bottom push rod all is connected with a horizontal push rod (8), positioning sleeve (3) is connected with horizontal push rod (8), the tapered end (9) that is fixed on the doorframe is the L type, and laterally push rod (8) go up with the corresponding positioning sleeve of tapered end on jack be one with the identical long shape hole of tapered end (9) insertion position geomery.

When door is closed, tapered end (9) will place the jack of positioning sleeve (3), if during each keyed end that distributes on the need lock door body, can make top and bottom push rod (2), (7) upper and lower respectively moving that tapered end (1) is inserted in the positioning sleeve corresponding on the wing by inserting key in the lockhole of center, and make tapered end (9) hook positioning sleeve (3) on the wing.

Embodiment 2

Fig. 3 one is installed in the example that uses on the window, in this example, the window wing is a scalable wing, and, center lock in the mechanical linkage which controls of installing on it is connected with the tapered end (9) of L type by push rod (10), and what install on the window frame corresponding with it is a positioning sleeve.And push rod (10) is positioned on the locator slide (11).

Claims

1, the comprehensive locking device of a kind of pick-proof door and window, its structure are that push rod is connected with center lock (5), it is characterized in that being connected with on the push rod tapered end (9) or positioning sleeve (3).And what lock with this tapered end and positioning sleeve is a positioning sleeve that matches (3) or tapered end (9), and tapered end (9) is the L type.

2, the comprehensive locking device of pick-proof door and window according to claim 1 is characterized in that to insert the position identical with the jack geomery of the corresponding positioning sleeve of tapered end and tapered end (9).
