Description
Technical Field
[0001] The utility model relates to the technical field of doors and windows, in particular to a hidden automatic closing hinge with a buffer. Background Art
[0002] Hinges play a crucial role in the opening and closing system of doors and windows. They not only need to provide a stable connection between the frame and sash, but also allow for flexible rotation between the two. This function is primarily achieved through the hinge's internal pivot mechanism and its two-piece housing.
[0003] However, traditional hinge designs have limitations. Once rotated to the open position, they typically remain stationary and lack the ability to automatically close after opening. In certain work environments or daily life scenarios, this automatic closing function is essential because it reduces manual operation and improves convenience.
[0004] Furthermore, some existing technologies attempting to implement automatic closing functions often rely on external tension springs or hydraulic mechanisms. These devices are not only complex in structure but also often take up additional space during installation, potentially affecting the aesthetics and usable space of doors and windows.
[0005] Therefore, developing a new type of hinge that can achieve automatic closing of doors and windows without sacrificing space and aesthetics has become a worthy research direction. This hinge should have a compact design and be able to integrate the automatic closing mechanism in an unobtrusive position, thus providing a more intelligent and user-friendly user experience without interfering with the normal use of doors and windows. Utility Model Content
[0006] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a hidden automatic closing hinge with buffering, so that the hinge can achieve buffering to avoid collision during the opening process, and can automatically rotate and close after opening, and make the structure of the hinge compact and concealed.

DETAILED DESCRIPTION
[0025] In order to make the purpose, principle and structure of the present invention more clear, it is further described below with reference to the accompanying drawings and specific embodiments.
[0026] See also Figure 1-7 The utility model provides a hidden automatic closing hinge with buffer, comprising:
[0027] The hinge frame adjustment shell 1 is provided with a cavity.
[0028] The hinge frame blade 2 is connected to the lower portion of the cavity of the hinge frame adjustment shell 1 , and a first through hole 2 . 1 is provided on one side of the hinge frame blade 2 .
[0029] A hinged door leaf 4, wherein the upper cross-section of the hinged door leaf 4 is concave, a second through hole 4.1 is formed at the end of one side of the upper portion of the hinged door leaf 4, and an extended connecting section is provided on the other side of the upper portion of the hinged door leaf 4;
[0030] The hinged door leaf adjusting shell 3 is connected to the extended connecting section of the hinged door leaf blade 4.
[0031] A spring shaft 5 is disposed within the first through-hole 2.1 of the hinge frame blade 2 and connected to the second through-hole 2.1 on the upper portion of the hinged door blade 2. The upper end of the spring shaft 5 can be a square or flat shaft. It is fixedly connected to the first through-hole 2.1 of the hinge frame blade 2 and movably connected to the second through-hole 4.1 of the hinged door blade 4 via a bearing consisting of a retaining ring 5.9, a steel ball sleeve 5.10, and a steel ball 5.11. Rotation of the hinge frame blade 2 drives the spring shaft 5 with it, allowing it to rotate freely within the second through-hole 4.1 without any obstruction.
[0032] The buffer 6 is arranged on one side of the upper cavity of the hinge frame adjustment shell 1. The hinge door leaf blade 4 can touch the buffer 6 when it rotates. The buffer 6 will give the hinge door leaf blade 4 a feedback force, and then gradually deform and shrink, so that the hinge frame adjustment shell 1 and the hinge door leaf adjustment shell 3 fit together. The buffer 6 can play a role of buffering and damping.
[0033] The hinge frame adjustment shell 1 is provided with step-structured connecting sections at both the upper and lower ends for connecting to door and window frame profiles.
[0034] The hinge frame blade 2 is connected to the hinge frame adjustment shell 1 through an adjusting screw.
[0035] The spring shaft 5 includes a shaft 5.1 and a spring 5.2. One end of the shaft 5.1 is inserted into the second through hole 4.1 on the upper portion of the hinged door leaf 4 through the bearing. The other end of the shaft 5.1 is provided with a plurality of guide wheel holes 5.3 and an automatic closing guide wheel 7 is inserted therein. The automatic closing guide wheel 7 is a tubular structure sleeved on the lower end of the shaft 5.1. The automatic closing guide wheel 7 is provided with an arc-shaped groove 7.1 spiraling upward along the circumference of the automatic closing guide wheel 7. The guide wheel pin 5.4 is inserted into the guide wheel hole 5.3 at the other end of the shaft and cooperates with the arc-shaped groove 7.1. The bottom of the automatic closing guide wheel 7 is provided with a spring 5.2 and a plastic gasket 5.7. The automatic closing guide wheel 7 and the spring 5.2 are arranged in the first through hole 2.1 of the hinge frame leaf 2. The bottom of the spring 5.2 is also provided with a screw 5.5 for adjusting the hinge automatic closing force. The screw 5.5 for adjusting the hinge automatic closing force is provided with an adjustment limit pin 5.6 and abuts against each other through a spring gasket 5.8.
[0036] See also Figure 7 , opening the door and window profile 8 can make the hinge frame adjustment shell 1 rotate, and the rotation of the hinge frame adjustment shell 1 can drive the rotation of the hinge frame blade 2 fixed to it, and the rotation of the hinge frame blade 2 drives the rotation of the rotating shaft 5.1 fixedly connected in the first through hole 2.1, and the guide wheel pin 5.4 in the guide wheel hole 5.3 on the rotating shaft 5.1 can rotate accordingly. Because the guide wheel pin 5.4 cooperates with the arc groove 7.1, when the guide wheel pin 5.4 rotates, the automatic closing guide wheel 7 can be pressed downward along the arc groove 7.1, and the spring 5.2 is compressed and accumulates elastic potential energy under the pressing action of the automatic closing guide wheel 7. The elastic coefficient of the spring 5.2 can be adjusted by adjusting the thread feed amount of the automatic closing force screw 5.5, that is, the elastic potential energy generated by the screw 5.5 during deformation can be adjusted, and the limit pin 5.6 is adjusted to ensure that the spring 5.2 only deforms in the vertical direction.
[0037] When the door and window profile 8 needs to be closed, it is only necessary to remove the force applied to the profile 8. The spring 5.2 releases the elastic potential energy generated by the deformation, and the automatic closing guide wheel 7 is lifted upward by the spring 5.2. The lifting of the automatic closing guide wheel 7 causes the guide wheel pin 5.4 to slide along the arc groove 7.1. Due to the spiral design of the arc groove 7.1, the sliding of the guide wheel pin 5.4 can drive the rotating shaft 5.1 to rotate. The rotation of the rotating shaft 5.1 further drives the hinge frame blade 2 and the hinge frame adjustment shell 1 to rotate in sequence, thereby realizing the automatic closing of the door and window.
[0038] During the above movement, since the rotating shaft 5.1 and the first through hole 2.1 are movably connected via the bearing, the rotating shaft 5.1 can be limited while the free rotation of the rotating shaft 5.1 in the first through hole 2.1 is not hindered.
[0039] The hinge door leaf adjustment housing 3 has step-structured connecting sections at both ends for connecting to the door and window leaf profiles. The hinge frame adjustment housing 1 is also provided with adjusting screws 9 for adjusting the installation position of the hinge frame adjustment housing 1 on the profile 8.
[0040] The above description is only a specific implementation method of this utility model, but the protection scope of this utility model is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by this utility model, can make equivalent substitutions or changes based on the technical solutions and new concepts of this utility model, which should be covered by the protection scope of this utility model.
