Description

Technical Field

[0001] This application belongs to the technical field of hinge structures, specifically relating to a concealed hinge structure. Background Technology

[0002] A hinge is a hinge device consisting of two metal pieces, mainly used to connect the moving parts of doors, windows, cabinets, and other objects. This hardware has the characteristic of quiet operation; brass hinges are widely used in door products to reduce noise, and their selection criteria include a structural design with built-in ball bearings to ensure smooth and silent opening and closing. However, most existing hinges are directly installed onto the door leaf with screws, which not only easily leads to hinge detachment but also may cause damage to the door leaf due to the concentrated pressure at the screw points. Therefore, a solution to these problems is urgently needed. Utility Model Content

[0003] The purpose of this application is to provide a concealed hinge structure to address the shortcomings of existing technologies. In practical applications, this structure can increase the strength of the connection and reduce the possibility of damage to the door leaf due to the installation of the hinge structure.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] A concealed hinge structure includes a mounting plate, a cross hinge, and mounting screws for fixing the two together. The mounting plate is mounted on the side of the corresponding outer door frame away from the cross hinge. The cross hinge includes a first hinge and a second hinge connected by a rotary bearing. Both ends of the first hinge, the second hinge, and the mounting plate are provided with corresponding mounting holes for the mounting screws to pass through.

[0006] As an improvement to the concealed hinge structure described in this application, the mounting plate includes a plate body and two horizontally extending mounting bodies on the upper and lower sections of the plate body, and the mounting holes are provided in the mounting bodies.

[0007] As an improvement to the concealed hinge structure described in this application, a gap is left between the two mounting bodies to form a clearance space, and the clearance space corresponds to the cross hinge.

[0008] As an improvement to the concealed hinge structure described in this application, the plate is provided with fixing holes and is configured to be fixedly installed on the back of the corresponding outer door frame by mounting screws.

[0009] As an improvement to the concealed hinge structure described in this application, the mounting screw passes through the first hinge and the corresponding outer door frame and is fixed to the mounting plate.

[0010] As an improvement to the concealed hinge structure described in this application, the concealed hinge structure also includes a fixing screw identical to the mounting screw structure, and the second hinge is fixed to the outer door sash by the fixing screw.

[0011] As an improvement to the concealed hinge structure described in this application, the thickness of the mounting plate is set between 3 mm and 6 mm.

[0012] The beneficial effects of this application are as follows: The concealed hinge structure of this application includes a mounting plate, a cross hinge, and mounting screws for fixing both. The mounting plate is installed on the side of the corresponding outer door frame away from the cross hinge. The cross hinge includes a first hinge and a second hinge connected by a rotating bearing. Both ends of the first hinge, the second hinge, and the mounting plate are provided with corresponding mounting holes for the mounting screws to pass through. In actual use, by setting the connection structure between the mounting plate installed on the side of the door frame away from the cross hinge and the cross hinge, the strength bearing of the hinge structure and the door frame installation can be transferred from the position of a single mounting hole to the position of the iron fixing plate. This realizes the transfer of the installation pressure bearing position from a point to a surface, dispersing the pressure force while increasing the installation firmness.

[0028] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. This specification and claims do not distinguish components based on differences in name, but rather on differences in function. The term "comprising" throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to." "Approximately" means that within an acceptable margin of error, those skilled in the art can solve the technical problem and substantially achieve the technical effect within a certain margin of error. Furthermore, terms such as "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] The following is in conjunction with the appendix Figures 1-5 The present application will be further described in detail with reference to specific implementation methods, but this is not intended to limit the present application.

[0032] Implementation

[0033] A concealed hinge structure includes a mounting plate 1, a cross hinge 2, and mounting screws 3 for fixing the two together. The mounting plate 1 is mounted on the side of the corresponding outer door frame 100 away from the cross hinge 2. The cross hinge 2 includes a first hinge 21 and a second hinge 22 connected by a rotating bearing 23. The first hinge 21, the second hinge 22, and both ends of the mounting plate 1 are provided with corresponding mounting holes 4 for the mounting screws 3 to pass through.

[0034] In this embodiment, the mounting plate 1 is installed on the side of the corresponding outer door frame 100 away from the cross hinge 2. The mounting screw 3 passes through the first hinge 21 and the corresponding outer door frame 100 and is fixed to the mounting plate 1. The second hinge 22 is fixed to the outer door sash 200 by the fixing screw 5. The structure of the fixing screw 5 is the same as that of the mounting screw 3, so that the mounting hole 4 is universal and the cross hinge 2 does not need to be considered when it is installed, thus reducing the installation difficulty.

[0035] In practical applications, by setting a connection structure between the mounting plate 1 installed on the side of the door frame 100 away from the cross hinge 2 and the cross hinge 2, the strength bearing of the hinge structure and the installation of the door frame 100 can be transferred from the position of a single mounting hole to the position of the mounting plate 1. This realizes the transfer of the bearing position of the installation pressing force from a point to a surface, dispersing the pressing force while increasing the installation firmness.

[0036] Specifically, the mounting plate 1 includes a plate body 11 and two horizontally extending mounting bodies 12 on the upper and lower sections of the plate body 11. Mounting holes 4 are provided in the mounting bodies 12. The plate body 11 has fixing holes 111, which are configured to fix the mounting plate 1 to the corresponding outer door frame 100 by mounting screws 6. A gap is left between the two mounting bodies 12 to form a clearance space 13. The clearance space 13 corresponds to the part of the cross hinge 2 that does not have mounting holes 4, which can further alleviate the pressure caused by installation.

[0037] Specifically, the thickness of the mounting plate 1 is set between 3 mm and 6 mm. In this embodiment, the thickness of the mounting plate 1 is set to 5 mm to achieve a better effect of dispersing the compressive force. The thickness can be adapted to meet actual needs.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this application is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this application are within the scope of protection of this application. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this application.
