Description

Technical Field

[0001] The present invention relates to the technical field of hinge structures, and in particular to a structure for increasing the load-bearing capacity of a hinge. Background Art

[0002] A hinge, also known as a hinge joint, is a mechanical device used to connect two solids and allow relative rotation between them. A hinge can be composed of movable components or foldable materials.

[0003] For example, in the Chinese patent with the application number: CN202111009040.9 and the application date of August 31, 2021: A hinge and its hinge seat, including an outer shell, a vertical fine-tuning mechanism, a horizontal fine-tuning mechanism, a first hinge seat, and a second hinge seat; the hinge and the hinge seat are connected through the vertical fine-tuning mechanism and the horizontal fine-tuning mechanism. The installation height of the hinge can be adjusted through the vertical fine-tuning mechanism while the hinge seat remains fixed, so as to adjust the relative height between the two objects connected by the hinge, enabling the two connected objects to be height-aligned. Also, the horizontal position of the hinge can be adjusted through the horizontal fine-tuning mechanism while the hinge seat remains fixed, so as to adjust the degree of overlap between the two objects connected by the hinge, enabling the two connected objects to fit tightly. The hinge structure in this invention patent is usually installed on the door frame and the door panel. The force of the hinge is transmitted to the door panel, and the thickness of the door panel clamping the hinge is limited, usually only 3-4 millimeters on one side. Therefore, it is often necessary to add reinforcing ribs and reinforcing plates outside the door panel of the hinge to increase the strength, which is costly, ugly in appearance, has a short service life of the hinge, and poor load-bearing effect. Therefore, there is a need for improvement. Summary of the Invention

[0004] The present invention provides a structure for increasing the load-bearing capacity of a hinge that can effectively disperse the force on the door panel or door frame where the hinge is installed, enhance the overall load-bearing capacity, has a long overall service life, and is small and convenient for installation; it solves the technical problems existing in the prior art, such as the single hinge structure, inability to disperse the force on the door panel or door frame where the hinge is installed, poor load-bearing effect of the door panel, and short service life.

[0005] The above technical problem of the present invention is solved by the following technical solution: A structure for increasing the load-bearing capacity of a hinge, comprising a horizontal plate and a vertical plate connected vertically. On one side of the horizontal plate close to the vertical plate, a hinge installation groove is provided. A fixed hinge seat is arranged in the hinge installation groove. A rotating hinge seat is connected to the outside of the fixed hinge seat through a hinge rod. A transfer base that surrounds or semi-surrounds the fixed hinge seat is arranged in the hinge installation groove at the connection of the horizontal plate and the vertical plate. The fixed hinge seat is installed on the transfer base, and the side walls of the transfer base are respectively fixed on the vertical plate and the horizontal plate. A clamping mechanism for increasing the stability between the transfer base and the fixed hinge seat is arranged on the side of the transfer base in contact with the fixed hinge seat. The clamping mechanism comprises a thread-shaped clamping protrusion integrally formed on one side of the fixed hinge seat in contact with the transfer side plate. An installation groove that fits the fixed hinge seat is provided on the transfer side plate close to the vertical plate side. A clamping groove that cooperates with the clamping protrusion is provided in the installation groove. The transfer base is also provided with a transfer installation mechanism for increasing the stability between the transfer base and the horizontal plate and the vertical plate. The transfer installation mechanism comprises a vertical plate installation structure and a horizontal plate installation structure. The vertical plate installation structure comprises a vertical plate positioning member and a vertical plate fixing member on the transfer side plate. The horizontal plate installation structure comprises a horizontal plate fixing member on the transfer bottom plate. The vertical plate positioning member comprises a fixed convex block arranged on the first transfer side plate. The vertical plate fixing member comprises a screw installation seat arranged on the first transfer side plate.The fixed hinge seat is installed inside the horizontal plate. The rotating hinge seat is installed outside the fixed hinge seat through a hinge rod. The rotating hinge seat can rotate around the fixed hinge seat. The weight borne by the rotating hinge seat will be transmitted to the horizontal plate through the fixed hinge seat. The horizontal plate is the main load-bearing plate. If the thickness of the horizontal plate is too thin or the weight on the rotating hinge seat is too large, it will cause the horizontal plate to break and affect the service life. The adapter base is embedded between the horizontal plate and the vertical plate, and the side walls of the adapter base are respectively installed on the horizontal plate and the vertical plate. The fixed hinge seat is installed on the adapter base. In this way, the force of the fixed hinge seat on the horizontal plate can be transmitted to the vertical plate through the adapter base, increasing the load-bearing capacity and service life of the horizontal plate. The function of the clamping mechanism is to increase the friction between the adapter base and the fixed hinge seat and enhance the stability between the adapter base and the fixed hinge seat. The clamping protrusion is integrally formed with the fixed hinge seat. The threaded clamping protrusion cooperates with the clamping groove to prevent the fixed hinge seat from shaking. The fixed hinge seat fits in the installation groove, reducing the gap between the fixed hinge seat and the adapter side plate. The closer fit of the two can make the force transmission effect more stable. The function of the adapter installation structure is to increase the stability between the adapter base and the horizontal plate and the vertical plate, and at the same time facilitate the transmission of the force on the horizontal plate to the vertical plate. The vertical plate positioning piece on the adapter side plate is connected to the vertical plate, making the whole adapter base connected to the vertical plate. The vertical plate fixing piece on the adapter side plate can, on the one hand, be connected to the vertical plate to strengthen the connection stability between the whole adapter base and the vertical plate, and on the other hand, can connect and install the adapter side plate and the fixed hinge seat, increasing the connection stability between the fixed hinge seat and the adapter side plate. Two vertical plate installation holes are pre-opened on the vertical plate. The fixed convex block and the screw installation seat can respectively correspond to one vertical plate installation hole. The fixed convex block and the screw installation seat can be respectively embedded in their corresponding vertical plate installation holes, and the fixed convex block, the screw installation seat and the vertical plate installation hole are in interference fit. Since the vertical plate is made of wood, the fixed convex block and the screw installation seat can be more easily embedded into the vertical plate installation holes, and at the same time, the connection stability between the adapter side plate and the vertical plate can be ensured.

[0006] Preferably, the adapter base is a U-shaped or L-shaped base. The adapter base includes two adapter side plates in contact connection with the vertical plate and an adapter bottom plate embedded inside the horizontal plate. The adapter base can be U-shaped or L-shaped. The L-shaped adapter base can semi-enclose the fixed hinge seat. In this invention, the U-shaped adapter base is taken as an example for illustration. The U-shaped adapter base can mostly enclose the fixed hinge seat, facilitating the transmission of the force on the fixed hinge seat to the vertical plate through the adapter base. The bottom of the fixed hinge seat is installed on the adapter bottom plate, and the side of the fixed hinge seat is installed on the adapter side plate. The adapter side plate is in contact connection with the vertical plate. In this way, the force of the fixed hinge seat on the horizontal plate can be effectively transmitted to the vertical plate, dispersing the force on the horizontal plate.

[0007] Preferably, the two adapter side plates include a first adapter side plate and a second adapter side plate that are parallel to each other. The first adapter side plate is in contact with the vertical plate, and the second adapter side plate is integrally formed with the adapter bottom plate. A transfer installation mechanism is provided on the first adapter side plate, and a clamping mechanism is provided on the second adapter side plate. The second adapter side plate is integrally formed with the adapter bottom plate, so that the force received by the fixed hinge seat will be transmitted to the second adapter side plate. The first adapter side plate is in contact with the vertical plate, so that the force on the second adapter side plate can be transmitted to the vertical plate. At the same time, the size of the first adapter side plate is larger than that of the second adapter side plate, which can increase the contact area with the vertical plate and thus enhance the effect of force transmission.

[0008] Preferably, the clamping mechanism further includes a plurality of clamping bumps integrally formed on the adapter side plate close to the vertical plate and embedded in the fixed hinge seat. The clamping protrusions can be embedded into the fixed hinge seat to increase the stability between the adapter side plate and the fixed hinge seat, effectively preventing the fixed hinge seat from moving along the adapter side plate. The number of clamping bumps is 2, and the number of clamping protrusions can be increased or decreased according to actual situations. In this invention, 2 clamping protrusions are taken as an example for illustration. The 2 clamping protrusions are symmetrically distributed on the adapter side plate and embedded in the fixed hinge seat, which increases the stability between the adapter side plate and the fixed hinge seat and prevents the fixed hinge seat from shaking in the adapter base.

[0009] Preferably, the horizontal plate fixing member is a bottom plate screw hole opened on the adapter bottom plate, and a limit screw is installed in the bottom plate screw hole. One end of the limit screw with a larger-sized nut is embedded in the horizontal plate. The limit screw is installed on the fixed hinge seat through the bottom plate screw hole. At this time, the nut of the limit screw can be embedded in the horizontal plate, playing the role of limiting and increasing stability.

[0010] Preferably, the horizontal plate installation structure further includes an adapter extension plate parallel to the adapter bottom plate. A hinge installation hole is opened on the adapter extension plate, and a hinge installation screw is provided in the hinge installation hole. The hinge installation hole is a hole that penetrates the fixed hinge seat and the adapter extension plate. A hinge installation screw is installed in the hinge installation hole, which can not only fix the fixed hinge seat on the adapter extension plate, but also fix the whole of the adapter extension plate and the fixed hinge seat in the horizontal plate.

[0011] Preferably, a fastening mechanism for increasing the friction between the fixed hinge seat and the adapter base is provided on the fixed hinge seat. The fastening mechanism includes a camshaft rotatably installed on the fixed hinge seat, and the camshaft contacts and tightens against the adapter side plate on the side away from the vertical plate. The camshaft can rotate within the fixed hinge seat. As the camshaft rotates, the protruding side of the camshaft will contact and tighten against the adapter side plate on the side away from the vertical plate, thereby increasing the stability between the fixed hinge seat and the adapter base and ensuring the tightness of their connection.

[0012] Preferably, side plate screw holes are provided on the first transfer side plate. By providing side plate screw holes on the extended part of the first transfer side plate into the horizontal plate and then installing screws in the side plate screw holes, the first transfer side plate can be fixed to the horizontal plate, enhancing the stability and fastening of the connection between the transfer base and the horizontal plate.

[0013] Preferably, a cover plate is provided on the fixed hinge seat above the hinge mounting hole. The cover plate is provided on the fixed hinge seat above the hinge mounting hole, covering the camshaft and the hinge mounting screw, shielding the adjusting parts to prevent accidental touch from causing structural loosening and also having a dust-proof effect.

[0014] Therefore, a structure for increasing the load-bearing capacity of a hinge according to the present invention has the following advantages: effectively dispersing the stress on the horizontal plate to the vertical plate, greatly increasing the load-bearing capacity of the horizontal plate, having a longer service life for the overall structure, and the transfer base structure is small and convenient for installation.
