[0027] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figures 1 to 3 As shown, this is an embodiment of the built-in profile window hinge of the present invention, including a fixed base 10, a support arm 20, and a connecting assembly 30; the connecting assembly 30 connects the fixed base 10 and the support arm 20 respectively; the connecting assembly 30 includes a connecting rod 31, a first load-bearing rod 32, a second load-bearing rod 33, and a sliding module 34. A groove 11 extending along its length is provided in the middle of the fixed base 10, and the sliding module 34 is installed in the groove 11 and slidably connected to the fixed base 10. The two ends of the connecting rod 31 are hinged to the support arm 20 and the fixed base 10 respectively, the two ends of the first load-bearing rod 32 are hinged to the support arm 20 and the sliding module 34 respectively, and the two ends of the second load-bearing rod 33 are hinged to the connecting rod 31 and the sliding module 34 respectively.

[0029] Please see Figure 4-6 In actual use, the fixing seat 10 is fixed to the inside of the frame profile 40, and the sash profile of the window sash 50 is installed on the support arm 20. When the window sash 50 is opened, the window sash 50 drives the support arm 20 to rotate in direction A, and the first load-bearing rod 32 pushes the sliding module 34 to move along the slide groove 11 in direction B. At this time, the support arm 20 and the window sash 50 as a whole will move in direction B, so that the window sash 50 sweeps over the frame profile 40, avoiding collision and ensuring the normal opening and closing of the window sash 50. In this utility model, the structure of the slide groove 11 being placed in the middle can further increase the displacement of the support arm 20 and the window sash 50 in direction B, thereby avoiding interference between the window sash 50 and the frame profile 40 during the opening process, so as to adapt to the thicker built-in profile.

[0030] The following section details the specific structure of hinges for windows with built-in profiles:

[0031] Please see Figure 3 The sliding groove 11 of the fixing base 10 includes a guide hole 111 and a recessed groove 112. The guide hole 111 is an elongated hole that vertically penetrates the fixing base 10. The recessed groove 112 is located on the upper end surface of the fixing base 10 and surrounds the guide hole 111. Please refer to... Figures 1 to 3 A corner 12 is provided at one end of the upper surface of the fixed base 10 (specifically, the end near the frame profile 40). The corner 12 is a V-shaped structure that opens toward the support arm 20. The corner 12 includes an inner wall 121 that is perpendicular to the upper surface of the fixed base 10. The inner wall 121 includes a guide surface 122 and a limiting surface 123 that are connected to each other. The limiting surface 123 extends along the length direction of the fixed base 10, while the guide surface 122 is inclined to the length direction of the fixed base 10.

[0032] The fixed base 10 is provided with multiple recessed mounting positions 13, and the recessed mounting positions 13 are provided with screw holes 131. The fixed base 10 is placed into the frame profile 40, and the screw holes 131 are aligned with the openings on the frame profile 40. The bolts are screwed in to complete the installation of the fixed base 10. Since the recessed mounting position 13 adopts a recessed structure, the head of the bolt will be hidden in the recessed mounting position 13, thereby preventing the bolt head from being higher than the upper end face of the fixed base 10, which would affect the rotation of the first load-bearing rod 32, the second load-bearing rod 33, the connecting rod 31 and the support arm 20.

[0033] In addition, the fixing seat 10 is also provided with multiple locking components 14. The locking components 14 include a fixing rivet 141 and a fixing tab 142 that are fixedly connected. Tightening the fixing rivet 141 causes the fixing tab 142 to rotate, thereby causing the fixing tab 141 to abut against the inner wall of the frame profile 40 to lock the fixing seat 10. At the same time, the locking components 14 can play a role in bearing pressure and withstand the weight of the window sash 50, making the structure more stable.

[0034] Please see Figure 3 The support arm 20 is provided with a third rotating hole 21 and a fourth rotating hole 22. The third rotating hole 21 is used to be hinged to the first load-bearing rod 32 via a shaft, and the fourth rotating hole 22 is used to be hinged to the connecting rod 31 via a shaft.

[0035] The support arm 20 has a horizontally extending protrusion 23 near the end of the frame profile 40. The protrusion 23 has a triangular cross-sectional shape and is used to cooperate with the corner bracket 12. When the window sash 50 is closed, the support arm 20 rotates towards the fixing seat 10. When it rotates to a certain angle, the protrusion 23 extends into the corner bracket 12 and abuts against the guide surface 122. After further rotation, the protrusion 23 is completely retracted into the corner bracket 12, at which point the protrusion 23 abuts against the limiting surface 123. On the one hand, the guide surface 122 guides the protrusion 23, that is, it guides the movement of the support arm 20; on the other hand, when the protrusion 23 is completely retracted into the corner bracket 12, the corner bracket 12 limits the protrusion 23, preventing the hinge from shaking when the window sash 50 is closed, thus affecting the structural stability. The support arm 20 is provided with a mounting hole 24, and the mounting bracket 22 is provided with a mounting block 25 perpendicular to it; both the mounting hole 24 and the mounting block 25 are used to connect with the window sash 50.

[0036] Please see Figure 3 The sliding module 34 includes a connecting plate 341, a sliding block 342, and an adjusting block 343. The sliding block 342 is slidably connected to the slide groove 11. The connecting plate 341 is located at the upper end of the fixed base 10 and is fixedly connected to the sliding block 342. The adjusting block 343 is located at the lower end of the fixed base 10 and is fixedly connected to the sliding block 342. The connecting plate 341, the sliding block 342, and the adjusting block 343 are all provided with a first rotating hole 344 and a second rotating hole 345. The first rotating hole 344 is used to hinge with the first load-bearing rod 32, and the second rotating hole 345 is used to hinge with the second load-bearing rod 33.

[0037] The sliding module 34 also includes a fastening screw 346 that vertically penetrates the connecting plate 341, the sliding block 342, and the adjusting block 343. Rotating the fastening screw 346 causes the connecting plate 341 and the adjusting block 343 to move closer or further apart, adjusting the clamping force of the connecting plate 341 and the adjusting block 343 on the fixing seat 10, thereby adjusting the sliding damping of the sliding block 342. This provides a certain degree of damping when opening and closing the window sash 50, and the damping is adjustable to meet user needs. Meanwhile, the adjusting block 343 includes a housing 3431 and a connecting block 3432. The housing 3431 protects the connecting block 3432, further improving structural stability.

[0038] Specifically, such as Figure 3As shown, the sliding block 342 includes a sliding body 3421 and a guide member 3422 disposed at the lower end of the sliding body 3421. The sliding body 3421 is slidably connected in the recessed groove 112 to prevent the protrusion from affecting the rotation of the first load-bearing rod 32, the second load-bearing rod 33, the connecting rod 31, and the support arm 20. The guide member 3422 is inserted into the guide hole 111, and the outer wall of the guide member 3422 abuts against the inner wall of the guide hole 111, thus guiding the linear sliding of the sliding block 342. The guide member 3422 is centrally located at the bottom of the sliding body 3421 and is cylindrical. The connecting plate 341, the sliding block 342, and the adjusting block 343 are all provided with connecting holes 3423, which are coaxially arranged with the guide member 3422. Fastening screws are threaded into the connecting holes 3423 of the connecting plate 341, the sliding block 342, and the adjusting block 343 to realize the assembly connection of the connecting plate 341, the sliding block 342, and the adjusting block 343.

[0039] Compared to existing technologies, the hinge for built-in profile windows involved in this utility model includes a fixed base 10, a support arm 20, and a connecting component 30. The connecting component 30 includes a connecting rod 31, a first load-bearing rod 32, a second load-bearing rod 33, and a sliding module 34. A groove 11 is provided in the middle of the fixed base 10, and the sliding module 34 is slidably connected to the groove 11. The groove 11 is centrally located, and both the first load-bearing rod 32 and the second load-bearing rod 33 have one end hinged to the sliding module 34. By adjusting the hinge structure, the displacement of the support arm 20 along the groove 11 is increased, thereby increasing the displacement of the window sash 50 and preventing interference between the window sash 50 and the frame profile 40 during opening, thus accommodating thicker built-in profiles. In addition, the sliding module 34 includes a connecting plate 341, a sliding block 342, and an adjusting block 343; by adjusting the clamping force between the connecting plate 341 and the adjusting block 343 and the fixed seat 10 through screws, the damping of the sliding block 342 sliding along the slide groove 11 can be adjusted; so that the damping of the window sash 50 is adjustable and the adjustment method is simple, which meets the user requirements.

[0040] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
