Abstract
A self-closing type hinge comprises a hinge shaft, a fan side hinge blade and a frame side blade. The fan side hinge blade and the frame side hinge blade are integrally connected in a hinged mode through the hinge shaft. The self-closing type hinge is characterized in that balls are arranged between the lower contact face of the fan side hinge blade which is located in the hinged connection place and the upper contact face of the frame side hinge blade which is located in the hinged connection place, the contact plane of the frame side hinge blade and the ball is an inclined contact face, and the inclined angle of the inclined contact face is 3 to 7 degrees. The self-closing type hinge improves the contact face of two hinge blades of the hinge based on an existing common hinge, enables the hinge blades to achieve automatic closing of an opened fan through cross component force of the self-gravity of the opened fan, is free from extra energy, economical, environment-friendly and strong in practical applicability.
Description
Technical field
The present invention relates to the hinge of a kind of door, window or wing, particularly relate to a kind of self-closing hinge, belong to E05D3/02 (2006.01) the I technical field in the International Patent Classification (IPC), be applied to some indoor opening door-leafs, but performance is not high wishes again the place that can realize autoshutdown when using opening door-leaf unmanned, such as washroom, locker etc. to closing.
Background technology
Existing hinge is made of by bearing pin is hinged left hinge, right hinge.Various hinges have appearred in published patent documentation, for example: publication number is a kind of " hinge " that the utility model patent of CN201794411U provides, comprise frame hinge, hinge axis and fan hinge, wherein, this frame hinge and this fan hinge are provided with reinforcing rib, utilize simultaneously existing design notch on the section bar, establish boss on the hinge, directly be inserted in the notch, then be screwed on section bar, solved the problem of hanging under the sash, becoming flexible.
Publication number is a kind of " hinge " that the utility model patent of CN 2771431Y provides, comprise left hinge, right hinge and rotating shaft, between the plane of rotation of the left and right hinge in the rotating shaft, be provided with thrust bearing, the change sliding friction is rolling friction, has advantages of that rotation is flexible, bearing capacity is large and the life-span is long.
Because hinge of the prior art is to use as the axis of rotation of the opening door-leafs such as door and window, want to realize that the opening door-leaf autoshutdown must just can finish by other devices such as door closers.Because the existence of these devices so that complex structure has increased the probability that goes wrong, has also affected the degree of freedom of opening door-leaf, and has increased engineering cost.Not very high position for some to closing performance requirement, thirst for that then a kind of simple mechanism is arranged, need not expend excess resource, can allow opening door-leaf when unmanned the use, realize autoshutdown, recover its cutting function.
Summary of the invention
The objective of the invention is to solve the problems referred to above that prior art exists, a kind of novel self-closing hinge is provided, do not changing outside its original function, can utilize the hinge place that certainly focuses on of opening door-leaf to produce cross component force, realize the opening door-leaf autoshutdown.Friction when reducing opening and closing weakens the loss to hinge, and this self-closing hinge has been set up ball especially, replaces sliding friction with rolling friction, makes its activity freely.
In order to solve the problems of the technologies described above, the technical scheme that the present invention provides is: this self-closing hinge, include hinge axis, fan side hinge and frame side hinge, fan side hinge and frame side hinge are integrally formed by hinge axis is hinged, be characterized in being provided with ball between the contact surface on the contact surface and frame side hinge under the fan side hinge of hinged place, the plane that frame side hinge contacts with ball is a contact inclined-plane, and the angle of inclination on this contact inclined-plane is 3-7 °.
The invention has the beneficial effects as follows: on the basis of the original design of ready-made hinge, the contact surface of two hinges of hinge is improved, the cross component force that it is produced simply by virtue of the opening door-leaf deadweight, just can realize the autoshutdown of opening door-leaf, need not to expend extra resource, economy is environmental protection again, and practicality is very strong.
Description of drawings
The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the outline drawing of self-closing hinge of the present invention.
Fig. 2 is the expanded view of self-closing hinge of the present invention.
Fig. 3 is the stereogram of self-closing hinge of the present invention.
Sequence number explanation among the figure: 1. hinge axis, 2. fan side hinge, 3. frame side hinge, 4. ball.
The specific embodiment
The present invention will be further described in detail below in conjunction with Fig. 1～Fig. 3.
The present invention provides this self-closing hinge and is made of hinge axis 1, fan side hinge 2, frame side hinge 3 and ball 4, fan side hinge 2 and frame side hinge 3 are by hinge axis 1 hinged being integrally formed, be provided with ball 4 between the contact surface on 2 times contact surfaces of fan side hinge of hinged place and the frame side hinge 3, replace sliding friction with rolling friction, make its activity freely, the plane machining that frame side hinge 3 contacts with ball 4 becomes to have certain angle of inclination, the plane that frame side hinge 3 is contacted with ball 4 is the contact inclined-plane, and the angle of inclination on this contact inclined-plane is 5 °.Then fan side hinge 2 under the Action of Gravity Field of opening door-leaf, can produce cross component force on the contact inclined-plane, this cross component force will force opening door-leaf to rotate around direction of principal axis to component, realizes the autoshutdown of opening door-leaf.
Claims (1)
1. self-closing hinge, include hinge axis, fan side hinge and frame side hinge, fan side hinge and frame side hinge are integrally formed by hinge axis is hinged, it is characterized in that being provided with ball between the contact surface on the contact surface and frame side hinge under the fan side hinge of hinged place, the plane that frame side hinge contacts with ball is a contact inclined-plane, and the angle of inclination on this contact inclined-plane is 3-7 °.
