Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description will be given to the embodiments, structures, features and effects of the push-pull locking mechanism for automatically turning a movable window according to the present invention with reference to the accompanying drawings and preferred embodiments.

Please refer to fig. 1 and fig. 2, which are schematic structural views of a push-pull locking mechanism for an automatic turnover movable window of the present invention, the push-pull locking mechanism includes a rotating cover plate 1 fixed on a device fixing plate through a rotating shaft, a torsion spring 2 for keeping the rotating cover plate 1 in an open state is disposed between the rotating shaft and the fixing plate, the torsion spring 2 is not stressed when the rotating cover plate is opened, and when the rotating cover plate is closed, the torsion spring generates torsion. Preferably, the torsion springs are at least two and are respectively positioned at two sides of the rotating cover plate.

Still slide in the spout of above-mentioned equipment fixing plate and be provided with slider 3, and be connected with the spring 4 that provides the power of outside removal for slider 3 between this slider 3 and the spout inner wall, be equipped with first trip on this slider 3, be equipped with the second trip on the above-mentioned rotatory apron, when rotatory apron 1 closure down, above-mentioned second trip presses on the guide inclined plane of first trip upper end earlier, when rotatory apron continues to push down, first trip compresses spring 4 and inwards slides under the effect on its upper end guide inclined plane, until rotatory apron lock is in place, the interlock of second trip and first trip realizes the lock locking of rotatory apron.

In an embodiment of the present invention, the outer side surface of the front end of the second hook is an inclined surface adapted to the guiding inclined surface of the upper end of the first hook.

The first hook and the sliding block can be of an integrally formed structure or can be two parts fixedly connected with each other.

In the embodiment of the present invention, one end of the spring 4 is located in the groove on one side of the slider 3, and the other end is located in the groove on the inner wall of the sliding groove.

The utility model discloses the process description of activity window locking and unblock as follows:

the slider 3 is in the reset state because the effect of spring 4 under not receiving the external force condition, when closing rotatory apron 1, the second trip on the rotatory apron 1 promotes first trip and makes slider 3 slide to the inboard, when rotatory apron lock targets in place, the interlock of first trip and second trip, rotatory apron and slider 3 keep the lock. When the rotating cover plate needs to be opened, the sliding block 3 is pushed inwards, when the sliding block 3 is forced to slide inwards to the first clamping hook to be separated from the second clamping hook, the sliding block 3 is separated from the rotating cover plate 1, and the rotating cover plate 1 automatically rotates and pops open under the action of the torsion spring 2.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed with the preferred embodiment, it is not limited to the present invention, and any skilled person in the art can make modifications or changes equivalent to the equivalent embodiment of the above embodiments without departing from the scope of the present invention, but all the modifications, changes and modifications of the above embodiments by the technical spirit of the present invention are within the scope of the present invention.
