Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hardware fittings, and in particular to a self-recoverable buffer hinge for building doors and windows. BACKGROUND

[0002] A hinge is a mechanical device used to connect two solid objects, allowing them to rotate relative to each other. It is mainly composed of a rotating pin shaft and a leaf, and is mainly used in building doors and windows.

[0003] The existing building doors and windows mainly use hinges to open and close the doors and windows. The working principle is that one side of the hinge is fixed to the outer wall door frame or window frame, and the other side is fixed to the door or window. The two are connected by a rotating pin shaft, thereby realizing the opening and closing function of the door and window.

[0004] In actual application, when the door is opened, the excessive force often causes the door and window to open too fast, which collides with the wall, causing the door and window to be damaged, and in severe cases, it can easily cause safety hazards. The service life of the hinge is also greatly affected. At the same time, when the door hinge rotates, it cannot be automatically closed, and when the number of people is too large, it is easy to cause unsafe events to occur, and manual closing is required at all times, so it is not suitable for areas with more people. The hydraulic door closer is installed in the ordinary building door and window, which is expensive on the one hand, and the building door and window is more, which will generate a large cost. On the other hand, the hydraulic door closer is installed at one end of the door frame or window frame, and the other end is installed on the door or window, which requires a lot of space. For some special-shaped structures, it is inconvenient, and in actual application, the guide rod of the hydraulic door closer often collides with the wall, causing damage to the door, window and wall to varying degrees. At the same time, it also needs to be installed independently when the door is installed and fixed, which reduces the efficiency of the door installation. SUMMARY

[0005] In order to overcome the defects in the prior art, the present application provides a self-recoverable buffer hinge for building doors and windows, which saves the large cost of installing a hydraulic door closer, greatly saves the labor cost of installation, and also protects the door, window and wall.

[0006] In order to achieve the above purpose, the present application provides a self-recoverable buffer hinge for building doors and windows, comprising:

[0007] a first leaf for mounting to a door frame or window frame;

[0008] a second leaf for mounting to a door leaf or window leaf, the side edges being rotatably connected to the side edges of the first leaf by a rotating pin shaft;

[0009] A return spring is installed between the first leaf and the second leaf, and the two ends of the return spring are fixedly connected to the first leaf and the second leaf respectively and apply a reverse force to the first leaf and the second leaf.

[0010] The return spring deforms as the second leaf rotates relative to the first leaf, causing the door to rotate away from the door frame to open the door. After the door is opened, it returns to its original position, thereby causing the second leaf to rotate closer to the door frame to close the door.

[0011] Alternatively, the return spring deforms as the second leaf rotates relative to the first leaf, causing the window sash to rotate away from the window frame to open the window sash, and then returns to its original position after the window sash is opened, thereby causing the second leaf to rotate closer to the window frame to close the window sash.

[0012] Preferably, the first leaf has a plurality of first mounting holes for securing the first leaf to the door frame or the window frame with the first bolt.

[0013] Preferably, the second leaf has a plurality of second mounting holes for securing the second leaf to the corresponding door leaf or window leaf with a second bolt.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects:

[0015] 1) The structure is simple and the integrated structure is easy to install, saving labor costs.

[0016] 2) The constituent materials are simple, the design principle is simple, and the manufacturing cost is low.

[0017] 3) It can protect and extend the service life of doors, windows and hinges. Attached Figure Description

[0022] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see Figure 1 As shown, this invention provides an integrated self-recovering buffer hinge for building doors and windows, including a first leaf 1 for installation to a door or window frame, a second leaf 2 for installation to a door or window sash, and a return spring 6. The side of the second leaf 2 is rotatably connected to the side of the first leaf 1 via a rotating pin 5. The return spring 6 is installed between the first leaf 1 and the second leaf 2, with both ends fixedly connected to the first leaf 1 and the second leaf 2 respectively, and applying opposing forces to the first leaf 1 and the second leaf 2. The return spring 6 deforms as the second leaf 2 rotates relative to the first leaf 1, causing the door sash to rotate away from the door frame to open the door, and then returns to its original position after opening, thereby causing the second leaf 2 to rotate closer to the door frame to close the door.

[0024] Alternatively, the return spring 6 deforms as the second leaf 2 rotates relative to the first leaf 1, causing the window sash to rotate away from the window frame to open the window sash. After the window sash is opened, it returns to its original position, thereby causing the second leaf 2 to rotate closer to the window frame to close the window sash.

[0025] Furthermore, in this embodiment, the first sheet 1 is provided with a plurality of first mounting holes 3 for fixing the first sheet 1 to the door frame or window frame with the first bolt. Preferably, the second sheet 2 is provided with a plurality of second mounting holes 4 for fixing the second sheet 2 to the corresponding door leaf or window leaf with the second bolt. The instructions require that, before construction, the construction personnel determine the positioning points of the corresponding mounting holes on the door frame, door leaf, or window frame and window leaf, and ensure that the door frame, door leaf, or window frame and window leaf are on the same horizontal line to guarantee the airtightness of the door leaf or window leaf later. After determining the positioning points, first install and fix the corresponding second leaf 2 on one side of the door leaf or window leaf using the second bolt and the second mounting hole 4. Then install the corresponding first leaf 1 on one side of the door frame or window frame. After completion, use a small wrench to start adjusting the return spring 6, while rotating the second leaf 2 to open the door leaf or window leaf and test the automatic return speed of the door leaf or window leaf to a suitable level. After installation, in this embodiment of the invention, the first leaf 1, the second leaf 2, the rotating pin 5, and the return spring 6 are an integrated structure, which is convenient to install, saves the large cost of installing hydraulic door closers, and also greatly saves the labor cost of installation. At the same time, it provides good protection for doors, windows, and walls.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
