[0033] See also Figure 1 The present embodiment provides a door and window hinge structure, including: a frame member 1, a fan member 2, at least two hinge members 3 and a plurality of rotating shafts, the plurality of rotating shafts including at least two first rotating shafts 4 and at least two second rotating shafts 5, one side of each hinge member 3 is rotationally connected to the frame member 1 through the corresponding first rotating shaft 4, and the other side is rotationally connected to the fan member 2 through the corresponding second rotating shaft 5; wherein, at least two hinge members 3 have the same shape and size, and the first rotating shaft 4 and the second rotating shaft 6 have the same shape and size.

[0034] The hinge part 3 and the rotating shaft of this embodiment are each a common accessory, and there is no need to design and manufacture each accessory separately, which is simple to process and has low manufacturing cost. At the same time, it reduces the difficulty of inventory preparation and warehouse management for manufacturers, and also reduces the complexity and error rate of the assembly process.

[0035] Furthermore, the two end surfaces of the hinge member 3 are arranged flush (such as Figure 2 As shown), and the hinge part 3 is made of extruded aluminum profile, therefore, the hinge part 3 only needs to be cut according to the required length during the processing, and no additional processing is required. This processing method is simple and efficient.

[0036] In this embodiment, please refer to Figure 2 and Figure 3 A mounting portion 6 is provided on the frame 1, and a connecting cavity 7 for mounting one side of the hinge member 3 is provided in the mounting portion 6. Frame mounting holes 8 are provided on opposite ends of the mounting portion 6, and both frame mounting holes 8 are connected to the connecting cavity 7. A frame connecting hole 9 is provided on one side of the hinge member 3, and the first rotating shaft 4 passes through one of the frame mounting holes 8, the frame connecting hole 9 and the other frame mounting hole 8 in sequence.

[0037] Since the mounting portion 6 with the connecting cavity 7 is provided on the frame 1, and the connecting cavity 7 is connected with the two frame mounting holes 8, the hinge 3 can be installed by passing the first rotating shaft 4 through the two frame mounting holes 8 and the frame connecting hole 9 at one time. This design greatly simplifies the installation process and improves the installation efficiency. The design of the two frame mounting holes 8 and the frame connecting hole 9 ensures that a stable connection is formed between the hinge 3 and the frame 1. The first rotating shaft 4 passes through these holes in sequence, which not only realizes the connection between the two, but also enhances the firmness of the connection, making the door and window more stable and reliable during use.

[0038] Furthermore, a frame profile fixing portion 10 is also provided on the frame member 1, and the frame profile fixing portion 10 is fixedly connected to the mounting portion 6.

[0039] Two parallel extension blocks 11, one connecting rod 12 and the frame profile fixing portion 10 enclose the connecting cavity 7 or the two parallel extension blocks 11 of the mounting portion 6 and multiple connecting rods 12 enclose the connecting cavity 7. This design enables the hinge member 3 to be conveniently and quickly installed in the connecting cavity 7. No complicated installation steps or tools are required, and the hinge member 3 only needs to be placed in the connecting cavity 7 and fixed, which greatly improves the installation efficiency; at the same time, the extension blocks 11, the connecting rod 12 and the frame profile fixing portion 10 can play a certain protective role on the hinge member 3.

[0040] In this embodiment, a first gasket 13 (such as Figure 1 shown).

[0041] The first gasket 13 is usually made of a material with certain elasticity and wear resistance, such as rubber or plastic. The first gasket 13 can avoid direct contact between the hinge 3 and the mounting portion 6, thereby reducing friction loss and noise between the hinge 3 and the mounting portion 6. This can not only improve the use comfort, but also extend the service life of the hinge 3 and the frame 1.

[0042] In this embodiment, please refer to Figure 2 and Figure 4 The fan member 2 is provided with a connecting portion 14 for installing the other side of the hinge member 3, and fan member mounting holes 15 are provided at opposite ends of the connecting portion 14.

During installation, the second rotating shaft 5 only needs to pass through the fan installation hole 15 and the fan connection hole 16 of the hinge member 3 in sequence to complete the connection between the hinge member 3 and the fan member 2. This design simplifies the installation steps and improves the installation efficiency. The hinge member 3 is connected to the fan member 2 through the second rotating shaft 5 to form a stable connection structure. This design allows the fan member 2 to remain stable during the opening and closing process.

[0044] In this embodiment, a second gasket 17 (such as Figure 1 shown).

[0045] The second gasket 17 is usually made of a material with certain elasticity and wear resistance, such as rubber or plastic. The second gasket 17 can avoid direct contact between the hinge 3 and the connecting portion 14, thereby reducing friction loss and noise between the hinge 3 and the connecting portion 14. This can not only improve the use comfort, but also extend the service life of the hinge 3 and the fan 2.
