Description

Technical Field

[0001] This utility model relates to the field of window hinge technology, specifically to a novel hinge. Background Technology

[0002] Casement windows are a type of window found in traditional residential houses. The window sash opens and closes by moving horizontally, hence the name "casement window." Hinges are installed on one side of the sash and connect it to the window frame. Depending on whether it opens outwards or inwards, they are divided into outward-opening and inward-opening casement windows. These windows are characterized by their simple construction, flexible opening, and good sealing performance when closed, making them the most widely used type of window in residential buildings.

[0003] Currently, the casement window hinges commonly found on the market have a small number of connecting rods, while the window body is relatively heavy. This makes the connecting rods prone to deformation and sagging, resulting in poor overall hinge stability. They are also prone to vibration or even detachment during use and cannot withstand high wind pressure. Furthermore, many hinges lack a locking structure that automatically engages the frame fixing seat and bracket when the window is closed by wind pressure, making their wind pressure resistance weak.

[0004] Meanwhile, existing casement window hinges generally have grooves or rails on the frame mounting base. After long-term use, dust or debris can easily accumulate in the grooves or rails, affecting the sliding of the slider and thus affecting the service life of the hinge. Furthermore, it is difficult to clean.

[0005] This utility model was made based on the above circumstances. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new type of hinge with a simple structure and flexible opening. This new type of hinge does not require an additional sliding structure between the frame fixing seat and the linkage component, making it easier to clean. Moreover, when the hinge is closed to close the window, the support arm and the frame fixing seat can automatically lock together, resulting in good wind pressure resistance.

[0007] This utility model is achieved through the following technical solution:

[0008] A novel hinge includes a frame fixing base and a bracket for mounting a window panel, and further includes a first short rod rotatably connected to the frame fixing base, a first long rod with one end hinged to the first short rod and the other end hinged to the frame end near the bracket, a second short rod rotatably connected to the bracket, and a second long rod with one end hinged to the second short rod and the other end hinged to the frame end near the frame of the frame fixing base, wherein the middle part of the second long rod is rotatably connected to the middle part of the first long rod.

[0009] In the novel hinge described above, both the first long rod and the second short rod are located below the support arm and above the second long rod, while the first long rod is located above the first short rod.

[0010] As described above, the novel hinge has a locking structure between the support arm and the frame fixing seat that improves the sealing effect between the support arm and the frame fixing seat when they are closed.

[0011] As described above, the novel hinge has a locking seat on the frame fixing base, and the locking structure includes a locking tip on the support arm and a lock hole on the locking seat that matches the locking tip.

[0012] In the novel hinge described above, the locking tip is an arc-shaped locking tip, and the lock hole is provided with a corresponding arc surface that matches the arc-shaped locking tip.

[0013] In the novel hinge described above, the width of the second long rod near the frame fixing seat end is greater than the width of the second long rod near the second short rod end.

[0014] In the novel hinge described above, the end of the first long rod that is hinged to the first short rod is bent outward relative to the middle of the first long rod.

[0015] As described above, the new hinge has an adjustment plate on the frame fixing seat for adjusting the installation position of the frame fixing seat on the window frame.

[0016] In the novel hinge described above, the second long rod is hinged to the first long rod, and the bottom of the first long rod is provided with at least one oil storage cavity, which is circumferentially distributed on the outer circumference of the hinge point between the second long rod and the first long rod.

[0017] In the novel hinge described above, the bottom of the second long rod is provided with at least one oil storage cavity, which is circumferentially distributed on the outer circumference of the hinge point between the second long rod and the frame fixing seat.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. The hinge structure of this utility model is simple. With a hinge structure with two four-bar linkages, the support arm can be opened and closed flexibly without the need to set a sliding structure between the frame fixing seat and the linkage component, which makes it easier to clean the window frame and the hinge.

[0020] 2. This utility model has a locking structure between the support arm and the frame fixing seat, which locks the support arm onto the frame fixing seat when the two are closed. This allows the support arm and the frame fixing seat to lock automatically when the window is closed, preventing them from being blown open by the wind and providing good wind pressure resistance.

[0021] 3. This utility model provides an adjusting plate on the frame fixing seat for adjusting the installation position of the frame fixing seat on the window frame. The adjusting plate moves left and right along the axial direction of the frame fixing seat and is fixed on the window frame with the frame fixing seat. The gap between the window sash and the window frame can be adjusted so that the window sash can fit more tightly with the window frame after the window is closed, thereby improving the sealing effect of the window sash and thus improving the wind pressure resistance.

[0022] To more clearly illustrate the structural features and effects of this utility model, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0027] like Figure 1-3 As shown, a novel hinge includes a frame fixing base 1 and a support arm 2 for mounting a window panel. It also includes a first short rod 3 rotatably connected to the frame fixing base 1, a first long rod 4 with one end hinged to the first short rod 3 and the other end hinged to the near-frame end of the support arm 2, a second short rod 5 rotatably connected to the support arm 2, and a second long rod 6 with one end hinged to the second short rod 5 and the other end hinged to the near-frame end of the frame fixing base 1. The middle portion of the second long rod 6 is rotatably connected to the middle portion of the first long rod 4. In this invention, the frame fixing base 1, the first short rod 3, the first long rod 4, and the second long rod 6 form a four-bar linkage, and the support arm 2, the first long rod 4, the second long rod 6, and the second short rod 5 also form a four-bar linkage.

[0028] The hinge of this utility model has a simple structure. By setting two four-bar hinge structures, they support and move together. There is no need to set an additional sliding structure (slide groove or slide rail) between the frame fixing seat and the linkage component. The support arm can be opened and closed flexibly, thereby opening and closing the window. This hinge structure omits slide groove or slide rail, making it easier to clean the window frame and window sash.

[0029] Specifically, the first long rod 4 and the second short rod 5 are both located below the support arm 2 and above the second long rod 6, with the first long rod 4 located above the first short rod 3. The frame fixing seat 1 is used to directly and indirectly support the connecting rod and support arm 2 connected above it, preventing the support arm 2 from sagging. More specifically, the width of the end of the second long rod 6 near the frame fixing seat 1 is greater than the width of the end of the second long rod 6 near the second short rod 5. This increases the support area of ​​the second long rod 6, disperses the pressure on the support arm 2, improves the structural strength between the connecting rods, and provides better wind pressure resistance.

[0030] like Figure 1-2 As shown, in this utility model, a locking structure 7 is provided between the support arm 2 and the frame fixing seat 1 to improve the sealing effect between the support arm 2 and the frame fixing seat 1 when they are closed. This allows the support arm 2 to automatically lock onto the frame fixing seat 1 when the window is closed, resulting in a better sealing effect between the window and the window frame, preventing the window from being blown open by the wind, and improving the wind pressure resistance of the hinge.

[0031] Specifically, in this embodiment of the invention, the frame fixing base 1 is provided with a locking seat 8, and the locking structure 7 includes a locking tip 71 provided on the support arm 2 and a locking hole 72 provided on the locking seat 8 that matches the locking tip 71. The locking seat 8 of this invention can be integrally formed with the frame fixing base 1 or separately provided. The two four-bar linkages are connected through the middle of the second long rod 6 and the middle of the first long rod 4, mutually restricting the opening and closing action of the support arm 2. When the rear end of the support arm 2 and the second long rod 6 move towards... Figure 1 When the support arm 2 is rotated in direction B to retract, the locking tip 71 of the support arm 2 rotates towards path A and enters the locking hole 72 on the frame fixing seat 1.

[0032] More specifically, the lock tip 71 is an arc-shaped lock tip 711, and the lock hole 72 is provided with a corresponding arc surface 721 that matches the arc-shaped lock tip 711. The arc-shaped lock tip 711 can enter the lock hole 72 more smoothly along the arc surface 721.

[0033] In this invention, the end of the first long rod 4 that is hinged to the first short rod 3 is bent outward relative to the middle of the first long rod 4. This makes it easier to retract the first long rod 4 onto the frame fixing seat 1 when closing the window, and also expands the opening angle of the support arm 2.

[0034] like Figure 1-3 As shown in the figure, the frame fixing seat 1 is provided with an adjusting plate 9 for adjusting the installation position of the frame fixing seat 1 on the window frame. In this embodiment, the adjusting plate 9 is movably installed on the frame fixing seat 1 along the axial direction of the frame fixing seat 1. The adjusting plate 9 moves left and right along the axial direction of the frame fixing seat 1, and cooperates with the frame fixing seat 1 to fix it on the window frame, adjusting the gap between the window sash and the window frame, so that the window sash can fit more tightly with the window frame after the window is closed, improving the sealing effect of the window sash, thereby further improving the wind pressure resistance effect.

[0035] Specifically, the adjusting plate 9 engages with the frame fixing seat 1 via eccentric rivets 11, thereby allowing for fine-tuning of the left and right positions of the door and window. For example... Figure 2 As shown in this embodiment, the frame fixing seat 1 is provided with an oblong hole 12, and the adjusting plate 9 is provided with a circular hole 91. The oblong hole 12 and the circular hole 91 are provided correspondingly. The eccentric rivet 11 passes through the oblong hole 12 and cooperates with the circular hole 91. The shape of the oblong hole 12 allows the eccentric rivet 11 to move inside it, so that the eccentric rivet 11 can rotate within a certain range, thereby realizing the fine adjustment of the left and right positions of the casement door and window. This allows the casement door and window to be adjusted according to the actual situation during the installation process, ensuring that the gap between the casement door and window and the window frame reaches the optimal state. This not only ensures the smooth opening of the casement door and window, but also improves the sealing performance of the casement door and window.

[0036] like Figure 3 As shown, in this invention, the second long rod 6 is hinged to the first long rod 4. The bottom of the first long rod 4 is provided with at least one oil reservoir 10, which is circumferentially distributed around the outer circumference of the hinge point between the second long rod 6 and the first long rod 4. Furthermore, the bottom of the second long rod 6 is also provided with at least one oil reservoir 10, which is circumferentially distributed around the outer circumference of the hinge point between the second long rod 6 and the frame fixing seat 1. When the second long rod 6 rotates relative to the first long rod 4, or when the second long rod 6 rotates relative to the frame fixing seat 1, a small amount of oil in the oil reservoir 10 can flow out to the hinge point, preventing rust on rivets and other components at the hinge point, and making the rotation between the connecting rods in the new hinge smoother. Moreover, by injecting a certain amount of lubricating oil into the oil storage cavity 10, an oil film is formed between the second long rod 6 and the first long rod 4 or between the second long rod 6 and the frame fixing seat 1, thereby reducing the coefficient of friction between the connecting rods or between the connecting rods and the frame fixing seat 1, which facilitates the swinging of the first long rod 4 and the second long rod 6, thus making the opening and closing of the doors and windows easier.
