Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and in particular to a door and window hinge structure and a door and window structure. Background Art

[0002] In the door and window lock system, the hinge, as a key component, not only bears the important task of supporting the window sash, but also is responsible for realizing the rotation, opening and closing and load-bearing functions of the window sash. For door and window types such as screen windows that need to be frequently disassembled and cleaned, it is particularly important to adopt a detachable hinge design. Traditional screen window hinge designs usually include two main methods: one is to achieve the detachable function by matching the rotating shaft on the hinge sash bottom plate with the detachable single-hole L-shaped sash fixing shaft hole; the other is to set a vertical plate on the hinge sash bottom plate, which cooperates with the sash fixing to achieve the detachable effect.

[0003] However, both of these traditional design methods have obvious deficiencies in practical applications. Due to the existence of the matching gap, whether it is through the matching of the rotating shaft and the shaft hole, or the matching of the vertical plate and the sash fixing piece, it is inevitable that the window sash will produce obvious shaking during the opening or closing process. This shaking not only affects the sealing and thermal insulation performance of the doors and windows, but may also cause the opening and closing operations of the doors and windows to become unsmooth, and even damage the structure of the doors and windows, thereby greatly reducing the user experience.

[0032] Embodiment 1:

[0033] See also Figure 1-3 The present embodiment provides a door and window hinge structure for connecting a window sash 1, comprising: a sash bottom plate 2, a connecting member 3 and a sash fixing member 4 for connecting the window sash 1, one end of the connecting member 3 is connected to the sash bottom plate 2, and at least two connecting holes 5 are provided on the sash fixing member 4, and at least two connecting holes 5 are located on the same straight line, and the other end of the connecting member 3 passes through the at least two connecting holes 5 to be connected to the sash fixing member 4.

[0034] In this embodiment, the connection member 3 is matched with the plurality of connection holes 5 on the fan fixing member 4 to reduce the allowable tilt between the connection member 3 and the fan fixing member 4, that is, to reduce the activity of the fan fixing member 4. Figure 4 As shown, the same size shaft matches the same size hole, and the fan fixing member 4 with double holes (i.e. Figure 4 a) in the figure is only tilted by 2°, and only has a single-hole L-shaped fan fixing member 4 (i.e. Figure 4 b) in the figure is tilted by 17°, so the double-hole sash fixing member 4 has a better anti-tilting effect, which can largely prevent the window sash 1 from shaking during use, thereby improving the user experience. At the same time, the connection method of the connecting member and the connecting hole makes the installation and removal process of the sash fixing member simple and quick. When installing, just align the connecting hole on the sash fixing member with the connecting member. When disassembling, just take the sash fixing member to easily separate the sash bottom plate and the sash fixing member.

[0035] Among them, the horizontal cross-sectional shape and size of the other end of the connecting member 3 are the same as the shape and size of the connecting hole 5. Such a design can ensure that the other end of the connecting member 3 can pass through the connecting hole 5 on the one hand, and can reduce the fitting gap between the connecting member 3 and the connecting hole 5 on the other hand, thereby reducing the shaking of the window sash 1 during use and improving the user experience.

[0036] In this embodiment, please refer to Figure 3 The fan fixing member 4 includes: a fan fixing plate 6 and a plurality of wing plates 7 fixedly connected to the fan fixing plate 6 , the plurality of wing plates 7 are all arranged on the same side of the fan fixing plate 6 , and one connecting hole 5 is correspondingly arranged on one wing plate 7 .

[0037] Compared with the L-shaped sash fixing member 4, the multiple wing plates 7 distribute the weight and stress of the window sash 1 to multiple fixing points, reducing the burden on a single fixing point. This design helps to reduce damage and deformation caused by stress concentration, and improves the durability and safety of the sash fixing member 4.

[0038] In some embodiments, in order to improve the connection strength of the door and window hinge structure, multiple connecting parts 3 can be set, and the other ends of the multiple connecting parts 3 pass through at least two connecting holes 5 to be connected to the sash fixing parts 4. The multiple connecting parts 3 can disperse the force, thereby reducing the load of a single connecting part 3 and improving the overall load-bearing capacity.

[0039] In this embodiment, the side edges of the fan fixing plate 6 are provided with side wings 8 (such as Figure 3 As shown), the window sash 1 is provided with a sliding groove 9 (as shown Figure 5 As shown), the side wing 8 is slidably installed in the sliding groove 9.

[0040] The design of the side wings 8 and the sliding grooves 9 makes it very simple to install, maintain and replace the sash fixing plate 6 with the window sash 1. The side wings 8 can be easily slid into the sliding grooves 9 on the window sash 1 without complicated fixing steps or tools, thereby greatly saving installation, maintenance and replacement time and cost.

[0041] Furthermore, two opposite sides of the sash fixing plate 6 are both provided with side wings 8 , and two sliding grooves 9 are provided on the window sash 1 , and each side wing 8 is slidably installed in the corresponding sliding groove 9 .

[0042] The sliding fit of the two side wings 8 in the sliding groove 9 reduces the friction and wear between the sash fixing plate 6 and the window sash 1, which helps to reduce the loss of components and improve the durability of doors and windows.

[0043] In this embodiment, the connecting member 3 is a rotating shaft, one end of which is connected to the fan bottom plate 2 , and the other end of which passes through at least two connecting holes 5 to be rotatably connected to the fan fixing member 4 .

[0044] The connection mode of the rotating shaft makes the installation and removal process of the fan fixing member 4 simple and quick. When installing, it is only necessary to align the connection hole 5 on the fan fixing member 4 with the rotating shaft. When removing, it is also only necessary to take the fan fixing member 4 to easily separate the fan bottom plate 2 and the fan fixing member 4.

[0045] In this embodiment, please refer to Figure 2 and Figure 3 , and also includes: a fixing member 10, a fixing hole 11 is provided on the fan fixing plate 6, one end of the fixing member 10 is connected to the fixing hole 11, and the other end of the fixing member 10 abuts against the window sash 1 to limit the relative sliding of the fan fixing plate 6 and the window sash 1.

[0046] The setting of the fixing member 10 is mainly used to achieve a stable connection between the sash fixing plate 6 and the window sash 1. One end of the fixing member 10 is connected to the fixing hole 11, and the other end abuts against the window sash 1 and presses against the window sash 1. The friction force between the fixing member 10 and the window sash 1 achieves a stable connection between the sash fixing plate 6 and the window sash 1.

[0047] The fixing member 10 may be a screw, a bolt or other component with a thread, and the fixing hole 11 may be a threaded hole. The threaded connection between the fixing member 10 and the fixing hole 11 can realize a stable connection between the sash fixing plate 6 and the window sash 1.

[0048] In this embodiment, when observed along the axial direction of the fixing hole 11 , the projection of the straight line formed by the two connecting holes 5 on the fan fixing plate 6 deviates from the center of the fixing hole 11 .

[0049] Since the connecting hole 5 does not overlap with the fixing hole 11, interference between the fixing member 10 and the connecting member 3 can be avoided during the installation of the fan fixing plate 6 and the fixing member 10. At the same time, the relevant components can be disassembled and installed more conveniently, which reduces the difficulty of maintenance and improves the maintenance efficiency.

[0050] The installation process of the door and window hinge structure of this embodiment is as follows: since the sash fixing parts 4 need to be installed on the upper and lower sides of the window sash 1, the upper sash fixing part 4 is first installed at the accurate position on the upper side of the window sash 1, and then the lower sash fixing part 4 is preliminarily fixed at an approximate position that does not affect the assembly of the lower hinge and the window sash 1, and then the upper sash fixing part 4 is connected to the connecting part 3 through the connecting hole 5, and then the window sash 1 is preliminarily placed on the sash base plate 2 of the lower hinge, and then the lower fixing part 10 is loosened, and then the sash fixing part 4 is slid downward to connect it to the connecting part 3 through the connecting hole 5, and then the fixing part 10 is tightened to achieve the final fixed connection between the window sash 1 and the hinge.

[0051] Embodiment 2:

[0052] In this embodiment, please refer to Figure 6-9The connecting member 3 includes: a connecting vertical plate 12 and a connecting fixing plate 13, the connecting vertical plate 12 and the connecting fixing plate 13 are fixedly connected and combined into an L shape, the connecting fixing plate 13 is connected to the fan bottom plate 2, and the connecting vertical plate 12 passes through at least two connecting holes 5 to connect to the fan fixing member 4.

[0053] Since the connecting fixing plate 13 is directly connected to the sash bottom plate 2, and the connecting vertical plate 12 is connected to the sash fixing member 4 through the connecting holes 5, the installation process becomes simple and direct. This design reduces the complexity of the installation process and improves the installation efficiency. The design of the L-shaped connecting member 3 allows the connecting fixing plate 13 to be adjusted according to the size and shape of the sash bottom plate 2, and the connecting vertical plate 12 is connected to the sash fixing member 4 through multiple connecting holes 5, which also increases the flexibility and adaptability of the installation.

[0054] In this embodiment, the fixing plate 13 is connected to the fan bottom plate 2 by rivets 14 (such as Figure 7 The rivet 14 connection has high strength and stability, which can ensure that the connection fixing plate 13 and the fan bottom plate 2 are firmly connected and not easy to loosen or deform. This connection method can withstand greater force and vibration, ensuring the stability and reliability of the structure.

[0055] In some embodiments, the connection fixing plate 13 is detachably connected to the fan bottom plate 2. Specifically, the connection fixing plate 13 is detachably connected to the fan bottom plate 2 by screws or bolts. The detachable design of the screw connection simplifies the maintenance and replacement process. The staff only needs to remove the corresponding screws to remove the damaged parts and then install new parts, which reduces the difficulty and cost of maintenance.

[0056] In this embodiment, please refer to Figure 6-9 , also includes: a fixing member 10, a fixing hole 11 is provided on the sash fixing plate 6, and an avoidance hole 15 is provided on the connecting vertical plate 12. The fixing member 10 passes through the avoidance hole 15 and the fixing hole 11 in sequence and abuts against the window sash 1. The fixing member 10 is connected to at least one of the avoidance hole 15 and the fixing hole 11.

[0057] The setting of the avoidance hole 15 can ensure that when the sash fixing member 4 is installed on the connecting member 3 and then the fixing member 10 is tightened to achieve a stable connection between the sash fixing member 4 and the window sash 1, the connecting vertical plate 12 will not hinder the installation of the fixing member 10, thereby simplifying the installation steps, improving the installation efficiency, and reducing the installation time and labor costs.

[0058] The fixing member 10 may be a screw or a bolt, the fixing hole 11 may be a threaded hole, and the avoidance hole 15 may be a blind hole. Through the threaded connection between the fixing member 10 and the fixing hole 11, a stable connection between the sash fixing plate 6 and the window sash 1 can be achieved.

[0059] The installation process of the door and window hinge structure of this embodiment is as follows: since the sash fixing parts 4 need to be installed on the upper and lower sides of the window sash 1, the lower sash fixing part 4 is first initially fixed in an approximate position that does not affect the assembly of the lower hinge and the window sash 1, and then the upper sash fixing part 4 is slid into the sliding groove 9 while being detached from the fixing part 10, and moved to the upper side of the lower sash fixing part 4, when the sash bottom plate 2 of the upper hinge is well matched with the window sash 1, the upper sash fixing part 4 is pushed to connect it with the connecting vertical plate 12 of the upper hinge, and then the fixing part 10 is installed to achieve the fixed connection between the upper hinge and the window sash 1, and then the window sash 1 is placed on the sash bottom plate 2 of the lower hinge, and then the fixing part 10 on the lower sash fixing part 4 is removed, and then the lower sash fixing part 4 is slid downward to connect it with the connecting vertical plate 12 of the lower hinge, and finally the fixing part 10 is installed to achieve the fixed connection between the lower hinge and the window sash 1.
