Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a hinge anti-tilting structure and a hinge. Background Technology

[0002] In door and window hardware systems, hinges play a crucial role in enabling various opening and closing functions of window sashes. The opening and closing of window sashes during daily use depends on the proper functioning of the hinges.

[0003] When existing hinge technologies are applied to casement windows, a significant problem exists. Due to the sash's own weight, it sags, which negatively impacts the hinge, particularly the hinge base plate, which is prone to warping and deformation. Such deformation directly causes the sash to tilt and sag. This tilting and sagging prevents the window from closing properly, severely affecting its functionality. Furthermore, this significantly reduces the window's load-bearing capacity. From a safety perspective, tilted and malfunctioning windows may fall, posing a serious risk to personal safety and property. From a user experience perspective, the window becomes difficult to operate, making both opening and closing challenging, greatly reducing user satisfaction with the window product.

[0004] Currently, several anti-tilting structures have been proposed on the market to address the issue of hinge base plate warping. One type involves placing an anti-tilting structure on the outside of the first link of the hinge base plate. However, this structure is far from the first link, and its actual anti-tilting effect is far less than that of an anti-pry structure connected directly to the first link. Another anti-tilting structure involves riveting a nut block below the adjustment plate. Tightening the nut block clamps the profile, achieving anti-tilting functionality without affecting the adjustment function. However, this structure has significant limitations. It utilizes very little space; for example, it is unsuitable for windows with an inward tilt design due to space constraints. Furthermore, it increases production costs, hindering product market promotion and widespread application. Utility Model Content

[0005] The purpose of this invention is to provide a hinge anti-warping structure and hinge, aiming to solve the problems of poor anti-warping effect and high cost of existing anti-warping structures.

[0006] This utility model embodiment provides a hinge anti-tilting structure, which is installed on a hinge. The hinge includes a first connecting rod and a base plate. One end of the first connecting rod and the base plate are rotatably connected by a riveting shaft. The hinge anti-tilting structure includes an anti-tilting member. The riveting shaft passes through the first connecting rod and the base plate in sequence and is connected to one end of the anti-tilting member. The anti-tilting member is provided with an anti-tilting part. When the hinge is installed on a window frame, the anti-tilting part abuts against the profile mounting groove of the window frame.

[0007] Furthermore, the anti-warping component also includes: a first fixing body, which is fixedly connected to the anti-warping part, and the first fixing body and the anti-warping part are located on the same plane.

[0008] Furthermore, a first recessed platform is provided on the base plate, and the first fixing body is installed on the side of the first recessed platform away from the first connecting rod, so that the anti-tilting part and the base plate form a first limiting groove for cooperating with the side wall of the profile mounting groove.

[0009] Furthermore, it also includes an eccentric shaft, the other end of which is connected to the base plate via the eccentric shaft.

[0010] Furthermore, the anti-warping portion is formed by the anti-warping member extending along the side wall direction of the profile mounting groove.

[0011] Furthermore, the width of the anti-warping portion is less than or equal to the width of the profile mounting groove.

[0012] Furthermore, the anti-warping component also includes: a second fixing body, the second fixing body being fixedly connected to the anti-warping part, the second fixing body and the anti-warping part being located on different planes so that a second limiting groove for cooperating with the side wall of the profile mounting groove is formed between the anti-warping part and the base plate.

[0013] Furthermore, the first connecting rod is provided with a first through hole, the base plate is provided with a second through hole, and the second fixing body is provided with a third through hole and a convex structure. The riveting shaft passes through the third through hole, the second through hole and the first through hole in sequence. The dimensions of the first through hole, the second through hole and the third through hole are all larger than the dimensions of the riveting shaft so that the riveting shaft has tilting space. When the shaft cap of the riveting shaft abuts against the convex structure, there is a gap between the second fixing body and the shaft cap of the riveting shaft.

[0014] Furthermore, the connection between the second fixing body and the anti-tilting part is an arc-shaped structure.

[0015] This utility model embodiment also provides a hinge, including: the above-mentioned hinge anti-tilting structure.

[0016] This utility model discloses a hinge anti-tilting structure and a hinge. The hinge anti-tilting structure is installed on the hinge, which includes a first connecting rod and a base plate. One end of the first connecting rod and the base plate are rotatably connected by a riveting shaft. The hinge anti-tilting structure includes an anti-tilting component. The riveting shaft passes through the first connecting rod and the base plate in sequence and is connected to one end of the anti-tilting component. The anti-tilting component is provided with an anti-tilting part. When the hinge is installed on the window frame, the anti-tilting part abuts against the profile mounting groove of the window frame. This utility model connects the first connecting rod and the anti-tilting component by riveting the shaft and abuts the anti-tilting component against the window frame. This allows the weight of the window sash carried by the first connecting rod to be transferred to the window frame, thus preventing the hinge base plate from warping and deforming, avoiding tilting and sagging of the window sash, and enabling the window sash to close normally. This improves the anti-tilting effect of the hinge and the user experience, as well as the load-bearing capacity and safety of the window sash, while also reducing the cost of the hinge.

[0044] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0045] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0046] Example 1:

[0047] Please see Figure 1-4 This embodiment provides a hinge anti-tilting structure, which is installed on a hinge 1. The hinge 1 includes a first connecting rod 2 and a base plate 3. One end of the first connecting rod 2 and the base plate 3 are rotatably connected by a riveting shaft 4. The hinge anti-tilting structure includes an anti-tilting component 5. The riveting shaft 4 passes through the first connecting rod 2 and the base plate 3 in sequence and is connected to one end of the anti-tilting component 5. The anti-tilting component 5 is provided with an anti-tilting part 51. When the hinge 1 is installed on the window frame, the anti-tilting part 51 abuts against the profile mounting groove 6 of the window frame.

[0048] In this embodiment, the first connecting rod 2 and the anti-tilting component 5 are connected by a riveting shaft 4, and the anti-tilting component 5 is abutted against the window frame. This allows the weight of the window sash carried by the first connecting rod 2 to be transferred to the riveting shaft 4. The riveting shaft 4 then transfers the force it bears to the anti-tilting component 5, which in turn transfers the force it bears to the window frame. This reduces or even eliminates the force exerted by the riveting shaft 4 on the base plate 3, preventing the base plate 3 of the hinge 1 from warping or deforming, thus avoiding tilting and sagging of the window sash. This allows the window sash to close normally, improving the anti-tilting effect of the hinge 1 and the user experience, as well as the load-bearing capacity and safety of the window sash, while also reducing the cost of the hinge 1. The riveting shaft 4 passes sequentially through the first connecting rod 2 and the base plate 3 and is rotatably connected to one end of the anti-tilting component 5. This rotatable connection can be a hinge, and is not limited to a specific rotating pair such as a sliding bearing type rotating pair, a rolling bearing type rotating pair, or other kinematic pairs that can achieve rotation. Of course, in some embodiments, the rotatable connection can also be a riveting connection.

[0049] In this embodiment, the anti-warping component 5 further includes: a first fixing body 52, which is fixedly connected to the anti-warping part 51, and the first fixing body 52 and the anti-warping part 51 are located on the same plane.

[0050] The first fixing body 52 has multiple fixing holes evenly distributed on it to facilitate secure connection with other components via bolts and riveting shafts 4. The anti-warping part 51 is located on the same plane as the first fixing body 52 and is fixed together, forming a more stable overall structure. This design effectively resists warping deformation caused by external forces or pressure, ensuring that the anti-warping part 5 remains flat and stable during use.

[0051] In this embodiment, a first recessed platform 31 is provided on the base plate 3 (e.g., Figure 1 As shown), the first fixing body 52 is installed on the side of the first recessed platform 31 away from the first connecting rod 2, so that the anti-tilting part 51 and the base plate 3 form a first limiting groove 61 for cooperating with the side wall of the profile mounting groove 6 (as shown). Figure 3 (As shown).

[0052] This design effectively enhances the stability of the entire structure. Because the anti-warping part 51 and the base plate 3 are firmly abutted against both ends of the sidewall of the profile mounting groove 6, the sidewall of the profile mounting groove 6 is securely positioned within the first limiting groove 61. This allows the anti-warping part 5 to better prevent warping, thereby improving the overall structure's resistance to deformation.

[0053] In this embodiment, it also includes: an eccentric shaft 7 (such as...) Figure 1 As shown), the other end of the anti-tilting component 5 is connected to the base plate 3 via an eccentric shaft 7.

[0054] By rotating the eccentric shaft 7, the anti-warping component 5 is moved along the length of the base plate 3, which in turn moves the riveting shaft 4 along the length of the base plate 3, thereby moving the first connecting rod 2 connected to the riveting shaft 4. This adjusts the left and right gap between the window sash and the window frame, thus achieving the purpose of adjusting the horizontal gap between the window sash and the window frame. Therefore, even if there are processing errors in the window frame or sagging of the window sash, the horizontal distance between the window sash and the window frame can be adjusted to achieve the best installation state.

[0055] For further details, please refer to Figure 5 The eccentric shaft 7 includes an eccentric section 71 and a connecting section 72 connected to the eccentric section 71. The eccentric section 71 is offset from the center of the connecting section 72. The eccentric section 71 passes through the base plate 3 and is rotatably connected to the other end of the anti-tilting member 5. When the eccentric shaft 7 is installed on the base plate 3, the side of the connecting section 72 connected to the eccentric section 71 is on the same horizontal plane as the side wall of the profile mounting groove 6.

[0056] The side connecting section 72 and eccentric section 71 is located on the same horizontal plane as the side wall of the profile mounting groove 6. This ensures that when the other end of the anti-tilting component 5 is mounted on the eccentric shaft 7, the anti-tilting component 5 is in a horizontal position. This guarantees that the contact between the anti-tilting component 5 and the side wall of the profile mounting groove 6 is a surface-to-surface contact, increasing the contact area between the anti-tilting component 5 and the side wall of the profile mounting groove 6. A larger contact area also helps to disperse stress, allowing the stress to be more evenly distributed on the contact surface when subjected to external forces, reducing the risk of component damage due to excessive local stress. This design improves the overall structural safety while extending the service life of related components, providing more reliable protection for the structure.

[0057] In this embodiment, the anti-warping part 51 is formed by the anti-warping member 5 extending along the side wall direction of the profile mounting groove 6.

[0058] By extending along the sidewall of the profile mounting groove 6, a continuous mechanical support structure is formed, which can effectively disperse warping stress; at the same time, the extension path in the sidewall direction is perpendicular to the force direction of the anti-warping part 51, which can generate an anti-torque effect.

[0059] In this embodiment, the width of the anti-warping part 51 is less than or equal to the width of the profile mounting groove 6.

[0060] Because the width of the anti-tilting part 51 is less than or equal to the width of the profile mounting groove 6, the installation process becomes more convenient. Installers can easily and accurately insert the anti-tilting part into the profile mounting groove 6 at an angle without additional adjustment or correction, thus saving installation time and reducing installation difficulty.

[0061] In this embodiment, please refer to Figure 1 It also includes at least one connector 8 and at least one nut 9, the connector 8 passing through the base plate 3 and connected to the nut 9, and when the connector 8 is tightened, the nut 9 abuts against the side wall of the profile mounting groove 6.

[0062] The cooperation between connector 8 and nut 9 ensures the stability of the connection between profile mounting groove 6 and base plate 3. Secondly, the operation is relatively simple by tightening connector 8 to make nut 9 abut against the side wall of profile mounting groove 6. Moreover, this connection method facilitates disassembly when maintenance or component replacement is needed; simply loosening connector 8 allows separation of profile mounting groove 6 from base plate 3, greatly improving maintenance efficiency. Simultaneously, this structure also has a degree of adjustability. If a slight gap or positional deviation is found between profile mounting groove 6 and base plate 3 during installation, the tightening of connector 8 can be adjusted to better abut nut 9 against the side wall of profile mounting groove 6, thereby achieving precise installation and ensuring the flatness and stability of the overall structure. Furthermore, when connector 8 is tightened into nut 9, it prevents base plate 3 from wobbling left and right, ensuring that anti-tilting part 51 disengages from the side wall of profile mounting groove 6, thus preventing anti-tilting part 5 from failing to function.

[0063] Furthermore, the connector 8 passes through the base plate 3 and is rotatably connected to the nut 9. The connector 8 can be an internal hex bolt, or other bolts or screws, etc. The rotatable connection can be a hinge. The rotatable connection is not limited to a specific rotating pair, such as a sliding bearing type rotating pair, a rolling bearing type rotating pair, or other kinematic pairs that can achieve rotation. Of course, in some embodiments, the rotatable connection can also be riveted.

[0064] In this embodiment, a second recessed platform 32 is provided on the base plate 3 (e.g., Figure 1 As shown), the nut 9 is installed on the second recessed platform 32 so that an auxiliary limiting groove 62 is formed between the nut 9 and the base plate 3 for mating with the side wall of the profile mounting groove 6 (as shown). Figure 6 (As shown).

[0065] This design effectively enhances the stability of the entire structure. Since the nut 9 and the base plate 3 are firmly abutted against both ends of the sidewall of the profile mounting groove 6, the sidewall of the profile mounting groove 6 is securely positioned within the auxiliary limiting groove 62, thereby better enabling the nut 9 and the connector 8 to perform their fixing functions.

[0066] Please see Figure 7 The installation method of hinge 1 in this embodiment is as follows: first tilt hinge 1 so that anti-tilting part 5 can be hooked into the side wall of profile mounting groove 6, then straighten hinge 1, and then tighten connecting part 8 to realize the installation of hinge 1.

[0067] Example 2:

[0068] Please see Figure 8-10This embodiment provides a hinge anti-tilting structure, which is installed on a hinge 1. The hinge 1 includes a first connecting rod 2 and a base plate 3. One end of the first connecting rod 2 and the base plate 3 are rotatably connected by a riveting shaft 4. The hinge anti-tilting structure includes an anti-tilting component 5. The riveting shaft 4 passes through the first connecting rod 2 and the base plate 3 in sequence and is connected to one end of the anti-tilting component 5. The anti-tilting component 5 is provided with an anti-tilting part 51. When the hinge 1 is installed on the window frame, the anti-tilting part 51 abuts against the side wall of the profile mounting groove 6 of the window frame.

[0069] In this embodiment, the first connecting rod 2 and the anti-tilting component 5 are connected by the riveting shaft 4, and the anti-tilting component 5 is abutted against the window frame. This allows the weight of the window sash carried by the first connecting rod 2 to be transferred to the riveting shaft 4. The riveting shaft 4 then transfers the force it bears to the anti-tilting component 5, which in turn transfers the force it bears to the window frame. This reduces or even eliminates the force exerted by the riveting shaft 4 on the base plate 3, preventing the base plate 3 of the hinge 1 from warping or deforming, thus avoiding the tilting and sagging of the window sash. This allows the window sash to close normally, improving the anti-tilting effect of the hinge 1 and the user experience, as well as the load-bearing capacity and safety of the window sash. At the same time, it also reduces the cost of the hinge 1.

[0070] For further details, please refer to Figure 10 and Figure 11 The anti-tilting component 5 also includes: a second fixing body 53, which is fixedly connected to the anti-tilting part 51. The second fixing body 53 and the anti-tilting part 51 are located on different planes so that a second limiting groove 63 is formed between the anti-tilting part 51 and the base plate 3 for cooperating with the side wall of the profile mounting groove 6.

[0071] Meanwhile, the second fixing body 53 can be provided with multiple positioning holes, which can accurately align with other components, thereby ensuring the stability of the entire structure. By setting the second fixing body 53 and the anti-warping part 51 on different planes, the rigidity and deformation resistance of the overall structure can be effectively increased. This not only better resists warping or twisting caused by external forces, but also provides more stable support.

[0072] Furthermore, the connection between the second fixing body 53 and the anti-tilting part 51 is an arc-shaped structure 531 (e.g., Figure 10 (As shown). The arc-shaped structure 531 ensures that the anti-tilting component 5 will not cause accidental injury to the operator during operation, and also helps to improve installation efficiency. In addition, when the second fixing body 53 and the anti-tilting part 51 are connected through the arc-shaped structure 531, this design can effectively distribute external stress or load to a larger area, thereby reducing the situation of single-point stress and improving the stability and durability of the overall structure.

[0073] In this embodiment, a first through hole 21 is provided on the first connecting rod 2 (e.g., Figure 12As shown), a second through hole 33 is provided on the base plate 3 (as shown). Figure 13 As shown), the second fixing body 53 is provided with a third through hole 532 and a convex structure 533 (as shown). Figure 10 As shown), the riveting shaft 4 passes sequentially through the third through hole 532, the second through hole 33, and the first through hole 21. The dimensions of the first through hole 21, the second through hole 33, and the third through hole 532 are all larger than the dimensions of the riveting shaft 4 so that the riveting shaft 4 has tilting space. When the shaft cap 41 of the riveting shaft 4 (as shown) Figure 11 When the second fixing body 53 (as shown) comes into contact with the convex hull structure 533, there is a gap between the second fixing body 53 and the shaft cap 41 of the riveting shaft 4.

[0074] The design of the convex bulge structure 533 creates a height difference between the two sides of the riveting shaft 4 (where the shaft cap 41 is riveted downwards) connected to the first connecting rod 2 and the base plate 3 (e.g., Figure 11 As shown, the distance E between the second fixed body 53 and the shaft cap 41 of the riveting shaft 4 is greater than the distance F between the shaft cap 41 of the riveting shaft 4 and the convex structure 533. At the same time, since the dimensions of the first through hole 21, the second through hole 33 and the third through hole 532 are all greater than the dimensions of the riveting shaft 4, the riveting shaft 4 can swing left and right instead of being riveted straight up and down. Therefore, the hinge 1 can swing left and right relative to the window frame, and the window sash can tilt inward with the hinge 1.

[0075] Please see Figure 14 The installation method of hinge 1 in this embodiment is as follows: first tilt hinge 1 so that anti-tilting part 5 can be hooked into the side wall of profile mounting groove 6, then straighten hinge 1, and then tighten connecting part 8 to realize the installation of hinge 1.

[0076] This embodiment also provides a hinge 1, including: the hinge anti-warping structure of the above embodiment.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
