Description

Wind-proof hinge

The utility model relates to the hinge that uses on the door and window in the building construction, relates in particular to a kind of Wind-proof hinge that can prevent to make because of wind-force the door and window closure.

The Chinese utility model patent that the patent No. is 91215638.4, notification number is 2101726U discloses a kind of Wind-proof hinge, it comprises convex page plate, concave page plate, hinge jaw, between convex page plate and concave page plate, be provided with protruding gripper shoe and recessed gripper shoe, be hinged between two gripper shoes.During use, open door and window and make the angle between two gripper shoes reach 180 °, this moment, wind-force can not make door and window close; When needs were closed the doors and windows, the hinge pop-up between the concave, convex gripper shoe made two gripper shoe disengaging activity dead points once artificially, just can close the doors and windows then, uses very inconvenient.

The purpose of this utility model is to provide a kind of Wind-proof hinge, and it can open or close door and window to direct convenience, and does not need any parts of mobile hinge.

For achieving the above object, the technical solution adopted in the utility model is: described Wind-proof hinge comprises: active page plate, fixed leaf plate, and active page plate and fixed leaf plate are hinged by hinge jaw; Fixed leaf plate is provided with pin, and pin is provided with gripper shoe and spring; The rear wall overlap joint of spring one end and fixed leaf plate, the other end contacts with gripper shoe, makes gripper shoe be subjected to downward elastic force all the time; Gripper shoe can be rotated around pin, and the bottom surface of gripper shoe contacts with the top of active page plate; The active page plate can be held in the cavity of fixed leaf plate, gripper shoe can be held in the cavity of active page plate.

Further technical scheme of the present utility model is: on the basis of said structure, be provided with roller at the top of active page plate, roller is arranged on the active page plate by roller pin, and the external surface of roller contacts with the bottom surface of gripper shoe.

The utility model has the advantages that: more direct convenience open or close door and window, use more laborsaving.

The utility model will be further described below in conjunction with the drawings and specific embodiments.

Fig. 1 is the utility model Wind-proof hinge open mode structural representation;

Fig. 2 is that the utility model Wind-proof hinge closes up the status architecture schematic diagram;

Fig. 3 is the structural representation of active page plate portion among Fig. 1.

As shown in Figure 1, described Wind-proof hinge comprises: active page plate 1, fixed leaf plate 2, and active page plate 1 and fixed leaf plate 2 are hinged by hinge jaw 3; Fixed leaf plate 2 is provided with pin 4, and pin 4 is provided with gripper shoe 5 and spring 6; One end of spring 6 and the rear wall of fixed leaf plate 2 overlap joint, the other end contacts with gripper shoe 5, makes gripper shoe 5 be subjected to downward elastic force all the time; Gripper shoe 5 can be rotated around pin 4, and the bottom surface of gripper shoe 5 contacts with the top of active page plate 1; As shown in Figure 2, active page plate 1 can be held in the cavity 10 of fixed leaf plate 2, gripper shoe 5 can be held in the cavity 11 of active page plate 1.

As shown in Figure 3, in the present embodiment, be provided with roller 7 at the top of active page plate 1, roller 7 is arranged on the active page plate 1 by roller pin 8, and the external surface of roller 7 contacts with the bottom surface of gripper shoe 5.The purpose that roller 7 is set is the power of can reducing friction, and uses more laborsaving; The top of active page plate 1 can certainly be arranged to smooth garden arcuation or other smooth form.

During use, fixed leaf plate 2 is installed on doorframe or the window frame, active page plate 1 is installed on door or the window and gets final product.

When hinge was in as shown in Figure 1 open mode, this moment, door and window just was in closed condition.When opening the door, active page plate 1 closes up to the direction of fixed leaf plate 2 under the promotion of door, and roller 7 moves and promotes gripper shoe 5 simultaneously to fixed leaf plate 2 directions along the bottom surface of gripper shoe 5 and upwards rotates; In the present embodiment, curved surface is arranged in the bottom surface of gripper shoe 5, when door and window opens to certain angle as greater than 60 ° the time, this moment, roller 7 also moved to the inner side of gripper shoe 5, promptly inwardly (near fixed leaf plate 2) is by behind the turning point 9 of curved surface, elastic force effect because of spring 6, gripper shoe 5 is just further pressed to fixed leaf plate 2 with active page plate 1 automatically, until the cavity 10 of active page plate 1 being compressed into fixed leaf plate 2,5 of gripper shoes are pressed in the cavity 11 of active page plate 1, be that hinge is in state as shown in Figure 2, this moment, door and window was opened fully.Because the elastic force effect of spring 6, wind-force can not make automatically closing door and window, thereby can prevent to smash the generation of adverse events such as glass of door and window effectively.

Close the door or during window, active page plate 1 leaves fixed leaf plate 2 under the drive of door or window opposite motion when promptly doing with above-mentioned opening the door; When door and window close to certain angle as less than 45 ° the time, this moment, roller 7 moved to the outer fix of gripper shoe 5, after promptly again outwards (close active page plate 1) passes through the turning point 9 of curved surface, gripper shoe 5 is under the effect of spring 6, promote active page plate 1 by roller 7 and further open until door and window is closed, hinge returns to open mode as shown in Figure 1 again.

In sum, when the open angle of door and window during less than 45 ° of angles, door and window can be closed automatically, and this more can demonstrate its advantage when using in the room that uses air-conditioning or heater unit, can save similar accessories such as extension spring is installed on door and window, uses very convenient.When the open angle of door and window during greater than 60 °, hinge can help further to open door and window automatically, and is more laborsaving during use.Certainly, the above-mentioned angle of opening automatically and closing the doors and windows can be provided with as required, and promptly the curve form by gripper shoe 5 bottom surfaces are set and the position of turning point 9 are provided with above-mentioned angle, and not only are confined on described 45 ° and 60 °.
