Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiment of the present invention, all other embodiments obtained by the person skilled in the art without creative work belong to the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present invention, it should be noted that the terms "middle", "upper", "lower", "horizontal", "inner", "outer", etc. indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship which the product of the present invention is usually placed in when in use, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used solely to distinguish one from another, and are not to be construed as indicating or implying relative importance.

Furthermore, the terms "horizontal", "vertical" and the like do not imply that the components are required to be absolutely horizontal or pendant, but rather may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected. Either mechanically or electrically. They may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.

Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Fig. 1-4 show an embodiment of the present invention, which is an automatic closing device for plastic-steel doors and windows. The present embodiment mainly consists of a driver 1 correspondingly mounted on the window sash and a plate 2 and a lock seat 3 mounted on the window frame.

As shown in fig. 4, for the latch bolt assembly 4: the riveting column 14 is riveted on the sliding plate of the driver 1, the handle is arranged in the gear hole of the driver 1, the handle is rotated to drive the sliding plate of the driver 1 to move up and down, and the bolt assembly 4 moves up and down along with the sliding plate. The bolt 16 of the bolt component 4 is provided with an inclined plane II15, and a spring is arranged below the bolt 16 and can move up and down.

As shown in fig. 3, for the gusset plate 2: the slider 13 is riveted on the pinch plate 2 through a rivet A5 and a rivet C12, one end of the tension spring 9 is connected with the rivet C12, and the other end of the tension spring 9 is fixed on the pinch plate 2 through a rivet B10. When the plane 18 of the slide block 13 is subjected to external force, the slide block 13 moves to the other side along the rivet A5 and the rivet C12 along the guide groove 8 along the straight groove 6, and when the external force of the plane 18 disappears, the slide block 13 returns under the action of the tension spring 9.

When a fire disaster happens, the window is automatically closed by falling off of the explosion beads of the existing window closer, and the lock tongue on the driver is matched with the frame piece to lock, so that the fire is prevented from spreading indoors. The specific mode is as follows:

when the window sash is in a flat-open state, the handle is in a horizontal position, the window sash rotates towards the direction of the window frame under external force, the inclined surface II15 of the lock tongue 16 is in contact with the inclined surface 17 of the sliding block 13, the lock housing 16 gradually slides into the sliding block 13, and the lock housing is automatically closed by the straight surface 11.

When the handle is turned to the plumb position, the driver 1 slides along with the handle, the bolt 16 slides out along the inclined surface III17, and the pin 19 is matched with the lock base 3 to lock the window. When the handle is opened, the handle rotates to the horizontal position, the driver sliding plate moves along with the handle, the bolt 16 is driven to contact with the plane 18 and move downwards, and meanwhile, the pin 19 is separated from the lock seat 3, and the handle window sash is pulled to be opened.

Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
