Description

Technical Field

[0001] This utility model relates to the field of building hardware accessories technology, and in particular to a hinge for aluminum alloy doors and windows. Background Technology

[0002] In existing building door and window systems, hinges are key components connecting door and window sashes to frames, and their performance directly affects the flexibility of opening and closing, sealing performance, and service life of doors and windows.

[0003] However, in the current technology, most common aluminum alloy door and window hinges are ordinary hinge structures or sliding hinges, and some parts are inconvenient to assemble quickly. Therefore, when drilling for installation, damage to a single part will render the whole thing unusable. At the same time, some hinges have a simple functional structure and lack adjustment mechanisms, making it difficult to fine-tune the height and level of the door and window after installation, thus presenting certain limitations.

Mounting component one includes a first connecting plate 104, which is movably connected to the support base 1 through two damping washers 103, and has a collar structure at one end for easy establishment of a hinge relationship with other components. Mounting component two includes a second connecting plate 105, which is also movably disposed between the two damping washers 103, and has a symmetrical sleeve structure on one side for expanding the connection method. A groove 1051 is provided on the surface of the second connecting plate 105 for limiting, guiding, or reducing structural weight. The overall structure is flexible and reliable, and is suitable for various adjustable connection occasions.

[0036] In this embodiment, the collar on the surface of the first connecting plate 104 is embedded in the groove 1051, the rubber bushing 1011 is embedded in the collar on the surface of the first connecting plate 104 and the second connecting plate 105, and the damping washer 103 is first fitted onto the surface of the internal thread sleeve 101 and in contact with the support seat 1. Then, the entire rubber bushing 1011 is moved to fit onto the outer surface of the internal thread sleeve 101, another damping washer 103 is placed on the other end of the rubber bushing 1011, and the fastening bolt 102 is threaded into the inside of the internal thread sleeve 101. The overall assembly of the equipment is carried out through the assembly components, which facilitates the assembly and replacement of parts.

[0037] In Example 2, a collar at one end of the first connecting plate 104 is embedded in the groove 1051 of the second connecting plate 105, achieving structural guidance and limiting connection. The collars on the first connecting plate 104 and the second connecting plate 105 are the same size and form a stable rotational connection with the internal threaded sleeve 101 through the rubber bushing 1011. A slider 201 and a spring 202 are provided between the two mounting plates 2 to achieve the guiding and elastic reset functions of the connection structure. A sliding rod assembly 1043 is provided on the inner wall of the first connecting plate 104, which forms a guiding fit with the corresponding slider 201. At the same time, it is connected to the mounting plate 2 through a long bolt 1042 to achieve position adjustment. A long bolt 2053 is provided at the bottom of the second connecting plate 105, which cooperates with another set of sliders 201 through the sliding rod assembly 2054 to achieve synchronous guidance and support. The spring 202 is fixed on the inner walls of the first connecting plate 104 and the second connecting plate 105 respectively, providing elastic restoring force for the entire structure and improving connection stability and operational comfort.

[0038] In this embodiment, rotating the long bolt 1042 inside the first connecting plate 104 causes the long bolt 1042 connected to the surface to move laterally left and right, and the slider 201 is limited by the sliding rod assembly 1043. When rotating the long bolt 1053 inside the second connecting plate 105, the mounting plate 2 on the surface is adjusted vertically, and the slider 201 is limited by the sliding rod assembly 1054.

[0039] Working principle: Before use, the collar on the surface of the first connecting plate 104 is embedded in the groove 1051, and the rubber bushing 1011 is embedded in the collar on the surfaces of the first connecting plate 104 and the second connecting plate 105. The damping washer 103 is pre-fitted onto the surface of the internally threaded sleeve 101 and contacts the support base 1. Then, the entire rubber bushing 1011 is fitted onto the outer surface of the internally threaded sleeve 101, and another damping washer 103 is placed on the other end of the rubber bushing 1011. The fastening bolt 102 is threaded into the internally threaded sleeve 101, thus assembling the entire device. The modular assembly facilitates the assembly and replacement of parts. Furthermore, rotating the long bolt 1042 inside the first connecting plate 104 causes the long bolt 1042 connected to the surface to move laterally left and right, and the slider 201 is limited by the sliding rod assembly 1043. When rotating the long bolt 1053 inside the second connecting plate 105, the mounting plate 2 on the surface is adjusted vertically, and the slider 201 is limited by the sliding rod assembly 1054. The springs 202 on the surfaces of the two mounting plates 2 are respectively connected to the surfaces of the first connecting plate 104 and the second connecting plate 105, which facilitates the reset operation. The mounting holes on the surface are used for planar adjustment of the position, which facilitates fine-tuning of the position and makes installation easier.
