Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically a metal hinge with self-buffering function. Background Technology

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can be made of movable components or foldable materials. Hinges are generally installed on cabinets or doors and windows, and are divided into detachable and fixed types. Currently, there is a type of metal hinge with a self-buffering function, mainly including hydraulic hinges (damping hinges), which are characterized by a buffering function when the cabinet door is closed, minimizing the noise generated by the cabinet door colliding with the cabinet body when it closes.

[0003] In the prior art, Chinese utility model patent CN211950055U discloses a metal hinge, including an upper hinge, a lower hinge, a connector for connecting the upper and lower hinges, several bolts and sleeves, wherein the upper hinge is installed on the door panel and the lower hinge is installed on the door frame. The upper hinge has a downward-opening groove and the lower hinge has an upward-opening internal threaded hole. The connector includes an upper hexagonal prism and a lower threaded post. The hexagonal prism is inserted into the groove of the upper hinge, and the threaded post is rotatably connected to the internal threaded hole by threads.

[0004] In the aforementioned technique, the bolt is passed through the hexagonal countersunk hole of the upper hinge and the through hole in the door panel. Then, the sleeve is inserted from the inside of the door panel and connected to the bolt. Similarly, the lower hinge is installed on the door frame. The connector is then connected to the internal threaded hole of the lower hinge through a threaded post. Finally, the upper hinge on the door panel is fitted onto the hexagonal prism of the connector through a downward-facing groove. However, after installation, over time, the bolts at the upper and lower hinges and the connector may be corroded by moisture in the air, which may lead to loosening and potentially cause the door panel to detach from the door frame.

[0005] In view of this, the present invention solves the above-mentioned technical problems by proposing a metal hinge with a self-buffering function. Utility Model Content

[0006] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a metal hinge with a self-buffering function. The threaded connection between the first and second threads allows the protective cover to be installed on top of the auxiliary bolt, preventing corrosion from air and extending its service life. Furthermore, the compression pad contacts the top of the auxiliary bolt, compressing it and reducing impact when opening the door. This prevents the auxiliary bolt from shaking violently, avoiding the risk of loosening and falling off due to shaking, and improving stability during fixing. This solves the problems mentioned in the background technology.

[0007] This utility model provides the following technical solution: a metal hinge with self-buffering function, comprising: a hinge body, multiple mounting blocks fixed on both sides of the hinge body, an auxiliary bolt connected to the internal thread of the mounting block, a first thread on the outer wall of the auxiliary bolt, a protective cover on the top of the mounting block, a second thread on the inner wall of the protective cover, the first thread and the second thread being threadedly connected, and a compression pad fixed inside the protective cover, the bottom of the compression pad contacting the top of the auxiliary bolt.

[0008] As a preferred embodiment of this utility model, the top of the protective cover has two storage slots, the inside of the storage slots contains a desiccant, the inner wall of the storage slots has two connecting holes, and a sealing plug is inserted into the inside of the storage slots.

[0009] As a preferred embodiment of this utility model, the hinge body has an internal mounting groove, a sound-absorbing cotton board is fixed inside the mounting groove, and the bottom of the hinge body has multiple sound-absorbing holes.

[0010] As a preferred embodiment of this utility model, a buffer plate is fixed inside the mounting groove.

[0011] As a preferred embodiment of this utility model, the top of the hinge body is provided with multiple fixing holes.

[0012] As a preferred embodiment of this utility model, the outer wall of the hinge body is coated with an anti-corrosion coating.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the hinge body is first fixedly installed using fixing holes and mounting parts, and then secured with auxiliary bolts. This increases the number of fixing points, making installation more secure and improving stability. Simultaneously, the threaded connection between the first and second threads allows the protective cover to be installed on top of the auxiliary bolt, preventing corrosion from air and extending its service life. Then, a compression pad contacts the top of the auxiliary bolt, compressing it and reducing impact when the door is opened, thus preventing violent shaking of the auxiliary bolt and avoiding the risk of loosening or falling off. This improves the stability of the fixing process. Furthermore, the desiccant dehumidifies the air inside the protective cover, keeping it dry and reducing external influences on the auxiliary bolt, further enhancing the fixing effect.
