Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, and in particular to an inward-opening and inward-tilting hinge. Background Technology

[0002] Inward-opening and tilt-and-turn windows are a common type of window, widely used in modern architecture because they combine both inward opening and tilt-and-turn mechanisms. The top hinge is one of the core components of an inward-opening and tilt-and-turn window; it not only bears the weight of the window but also ensures a good seal when the window is closed.

[0003] Currently, most inward-opening and tilt-and-turn hinges on the market achieve a sealing effect through the cooperation of a pin and a sealing locking block on the side of the hinge. This design has some drawbacks. First, the structure is complex, usually requiring multiple components to work together, such as the pin, locking block, and spring. This complex structure not only increases production costs but also makes installation and maintenance more difficult. Second, because the fit between the pin and the locking block requires high precision, they are prone to wear after long-term use, leading to a decrease in sealing performance and even problems such as air leakage and water leakage.

[0004] Therefore, the industry urgently needs an inward-opening and inward-tilting hinge with a simple structure and reliable sealing performance to solve the above-mentioned problems in the existing technology. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an inward-opening and inward-tilting hinge.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] 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.

[0035] like Figures 1 to 9 As shown, this is an embodiment of the present invention, which provides an inward-opening and tilt-and-turn hinge. Its function is to connect the door and window sash and the door and window frame. It is mainly used in inward-opening and tilt-and-turn windows, which are windows that can open inwards and tilt upwards inwards. In order to ensure the sealing effect, both the door and window sash and the door and window frame are provided with sealing strips.

[0036] The aforementioned inward-opening and tilting hinge includes a sash connecting assembly 10, a connecting rod 20, and a frame connecting assembly 30. The sash connecting assembly 10 is used to connect with the door / window sash, and the frame connecting assembly 30 is used to connect with the door / window frame. The two ends of the connecting rod 20 are rotatably connected to the sash connecting assembly 10 and the frame connecting assembly 30, respectively. The relative rotation of the sash connecting assembly 10, the connecting rod 20, and the frame connecting assembly 30 enables the door / window sash to be closed or opened. The sash connecting assembly 10 includes a fixed component 11, a sliding rod 12, and a movable component 13. The sliding rod 12 is slidably connected to the fixed component 11 and one end is connected to the movable component 13. The fixed component 11 is rotatably connected to one end of the connecting rod 20. The movable component 13 is provided with a sealing lock post 14. The connecting rod 20 is provided with a middle groove 21. The frame connecting assembly 30 includes a first connecting rod 31 rotatably connected to the connecting rod 20. The bottom of the first connecting rod 31 is provided with a vertically arranged sealing lock block 32. It should be added that the other end of the first link 31 is connected to the control handle of the inward opening and tilting window through the linkage hardware. When the control handle is rotated, it can drive the fixed component 11 and the movable component 13 to move closer or further apart.

[0037] In actual use, when it is necessary to close the door or window sash and achieve a sealing effect, push the door or window sash so that it moves toward the door or window frame. At this time, the connecting rod 20 swings, and the sash connecting assembly 10 moves toward the frame connecting assembly 30. It should be noted that, as Figure 5 As shown, at this time, the sealing lock pin 14 has not entered the intermediate groove 21, therefore the sealing lock pin 14 does not interfere with the first connecting rod 31. When the door and window sash moves into the door and window frame, as... Figures 6 to 8 As shown, at this time, the fan connecting assembly 10, the connecting rod 20, and the frame connecting assembly 30 overlap vertically; then, rotating the control handle causes the movable component 13 to move closer to the fixed component 11. At this time, the sealing locking pin 14 enters the intermediate groove 21 and slides along the intermediate groove 21. After sliding a certain distance, as shown... Figures 1 to 5 As shown, the sealing lock pin 14 presses against the sealing block 32, causing the sealing strips of the door / window sash and the door / window frame to squeeze against each other, achieving a sealing effect. Simultaneously, the sealing lock pin 14 engages with the intermediate groove 21, restricting its movement in the width direction of the intermediate groove 21, thus locking the door / window sash. Conversely, when it is necessary for the door / window sash to open or tilt inwards, rotating the control handle moves the movable component 13 away from the fixed component 11, disengaging the sealing lock pin 14 from the intermediate groove 21 and releasing the lock on the door / window sash.

[0038] The structure of the fan connection component 10 will be described in detail below:

[0039] Please see Figure 1-9 The fixing component 11 is fixed to the door / window sash, and the bottom of the fixing component 11 is provided with a movable groove 111 extending along its own length. The fixing component 11 is provided with a vertically arranged limiting member 112. In this embodiment, the limiting member 112 is a threaded columnar hardware, and the bottom end of the limiting member 112 vertically protrudes from the bottom surface of the fixing component 11. A positioning block 113 is fixedly provided at the upper end of the fixing component 11. The positioning block 113 is provided with a vertically penetrating positioning groove 114, wherein the positioning groove 114 includes a first locking position 114a and a second locking position 114b arranged opposite to each other along the length direction of the positioning block 113, wherein the first locking position 114a and the second locking position 114b are both provided with protrusions 114c at the junctions with the positioning groove 114.

[0040] Please see Figure 1-9 The slide rod 12 is slidably connected to the movable groove 111 of the fixed component 11; one end of the slide rod 12 is connected to the movable component 13; the other end of the slide rod 12 is fixedly provided with a connector 121, and the slide rod 12 is connected to the linkage hardware through the connector 121 to realize the connection with the control handle. In addition, the slide rod 12 is provided with a limiting groove 122 extending along its own length direction, and the bottom end of the limiting component 112 is inserted into the limiting groove 122; when in use, the control handle drives the slide rod 12 to slide in the movable groove 111, at which time the limiting component 112 slides in the limiting groove 122. It can be understood that the length of the limiting groove 122 is the maximum distance of relative sliding between the fixed component 11 and the movable component 13; the limiting component 112 cooperates with the limiting groove 122 to improve the stability of relative sliding between the movable component 13 and the fixed component 11.

[0041] Please see Figure 3 The bottom of the movable component 13 is provided with a sound-silencing block 131. The sound-silencing block 131 is made of elastic plastic material. When the movable component 13 slides, the sound-silencing block 131 cooperates with the profile groove of the door and window sash to reduce the noise during sliding and ensure smooth and stable sliding.

[0042] The movable component 13 is provided with a coaxially arranged and interconnected sinking groove 132 and a connecting hole 133. The sinking groove 132 is disc-shaped. Correspondingly, the sealing locking pin 14 includes an integrally formed pressing pin 141, a rotating disk 142 and a connecting pin 143 arranged sequentially from top to bottom. The pressing pin 141 is located at the upper end of the rotating disk 142 and the axis of the pressing pin 141 coincides with that of the rotating disk 142. The connecting pin 143 is located at the lower end of the rotating disk 142 and the connecting pin 143 is eccentrically arranged with the rotating disk 142. During assembly, the connecting pin 143 is installed in the connecting hole 133 and the rotating disk 142 is movably connected in the sinking groove 132. The clamping pin 141 is used to cooperate with the sealing block 32. When the connecting pin 143 rotates around the axis of the connecting hole 133, the clamping pin 141 is eccentrically adjustable. Adjusting the position of the clamping pin 141 ensures that it can press the sealing block 32 tightly, thus ensuring a sealing effect. Furthermore, the upper end of the clamping pin 141 is provided with a polygonal hole 144. In this embodiment, an internal hexagonal hole is used to cooperate with tools such as wrenches to realize the rotation of the sealing block 14, thereby adjusting the position of the clamping pin 141.

[0043] The structure of connecting rod 20 will be described in detail below:

[0044] Please see Figure 1-9 In this embodiment, the connecting rod 20 includes an integrally formed first horizontal segment 22, a connecting segment 23, and a second horizontal segment 24 arranged sequentially. The first horizontal segment 22 and the second horizontal segment 24 are respectively used to connect with the fan connecting assembly 10 and the frame connecting assembly 30. The connecting segment 23 is inclined, such that the first horizontal segment 22 is higher than the second horizontal segment 24. Specifically, the top of the sealing lock post 14 is lower than the first horizontal segment 22, and the top of the sealing lock post 14 is lower than the second horizontal segment 24. An intermediate groove 21 is provided in the connecting segment 23 and extends to the first horizontal segment 22 and the second horizontal segment 24 at both ends. Figure 5 and Figure 8 As shown, when the movable component 13 and the fixed component 11 are relatively close, the sealing locking pin 14 enters the intermediate groove 21 through the bottom of the first horizontal section 22; conversely, when the movable component 13 and the fixed component 11 are relatively far apart, the sealing locking pin 14 exits the intermediate groove 21; the state switching is achieved through the above operation.

[0045] In addition, a movable column 25 is provided at the connection between the connecting rod 20 and the fixed component 11. The movable column 25 is fixedly connected to the connecting rod 20 and is inserted into the positioning groove 114 on the fixed component 11. When the door or window sash is opened or closed, the movable column 25 moves along the positioning groove 114. Specifically, when the door or window sash is fully opened, the movable column 25 enters the first locking position 114a, and when the door or window sash is fully closed, the movable column 25 enters the second locking position 114b. Since both the first locking position 114a and the second locking position 114b are provided with protrusions 114c, the movable column 25 is restricted from detaching, thereby improving the stability of the door or window sash in use.

[0046] The structure of the frame connector component 30 will be described in detail below:

[0047] Please see Figure 1-9 The frame connecting assembly 30 includes a first connecting rod 31, which has multiple holes for connecting with the door and window frame. The sealing lock block 32 includes an integrally formed pressing part 321 and a guide part 322. The pressing part 321 is rectangular and extends along the length of the first connecting rod 31. The guide part 322 is arc-shaped and located at one end of the pressing part 321. The guide part 322 guides the sealing lock pin 14. When the movable member 13 and the fixed member 11 are relatively close, the sealing lock pin 14 passes through the guide part 322 and abuts against the pressing part 321.

[0048] Finally, please see Figure 3 To ensure the relative swing of the fan connecting assembly 10 and the frame connecting assembly 30, a second connecting rod 40, a third connecting rod 50, and a fourth connecting rod 60 are also provided. The second connecting rod 40 connects the fixing member 11 and the connecting rod 20 respectively. The third connecting rod 50 connects the connecting rod 20 and the first connecting rod 31 respectively. The fourth connecting rod 60 connects the connecting rod 20 and the first connecting rod 31 respectively. At the same time, the third connecting rod 50 and the fourth connecting rod 60 are cross-hinged.

[0049] Compared to existing technologies, the inward-opening and tilt-and-turn hinge of this utility model includes a sash connecting assembly 10, a connecting rod 20, and a frame connecting assembly 30. The sash connecting assembly 10 includes a fixed component 11, a sliding rod 12, and a movable component 13, with a sealing locking pin 14 provided on the movable component 13. The connecting rod 20 has a central groove 21. The frame connecting assembly 30 has a sealing locking block 32. When the door / window sash is closed, the sealing locking pin 14 passes through the central groove 21 and engages with the sealing locking block 32. Through the mutual cooperation of the sealing locking pin 14, the central groove 21, and the sealing locking block 32, the sealing strips of the door / window sash and the door / window frame are squeezed against each other, resulting in a good sealing effect. At the same time, the above structure makes the overall structure compact and stable, with a long service life, improving the reliability of inward-opening and tilt-and-turn doors and windows.

[0050] 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.
