Description

Technical Field

[0001] The utility model relates to the technical field of door and window structures, in particular to a high-load-bearing window sash hinge and an outward-opening window structure. Background Art

[0002] Outward-opening windows in buildings are casement windows whose sash partially or entirely protrudes outside when opened. Outward-opening windows are a type of casement window and are widely used in urban commercial and residential buildings, office buildings, high-end residences, villas, and other mid- to high-end structures. Casement windows come in two types: inward-opening and outward-opening. Inward-opening windows are convenient for cleaning, while outward-opening windows take up less space when open.

[0003] Existing outward-opening window structures typically include a window frame with hardware slots, to which the window sash is mounted via a sash hinge. However, the sash hinge is typically mounted on the front side of the window frame (i.e., the side facing the outside of the window). For heavier sashes, the sash hinge structure has poor load-bearing properties and is prone to excessively concentrated stress on the hinge, leading to damage due to localized excessive stress. This shortens the hinge's service life and places excessive demands on the material. Therefore, this type of sash hinge is clearly unsuitable for outward-opening window structures with heavier sashes. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a high-load-bearing window hinge and an outward-opening window structure. This high-load-bearing window hinge has a high load-bearing capacity, is not only suitable for the installation of heavy window sashes, but also can prolong the service life of the window hinge. The technical solution adopted is as follows:

[0005] A high-load-bearing window sash hinge, comprising a window frame mounting base plate and a window sash mounting top plate, characterized in that: it also includes a sliding member, a first connecting rod, a second connecting rod and a third connecting rod, the middle section of the window frame mounting base plate is provided with a strip slide extending along its length direction, the sliding member is installed in the strip slide groove and slidably cooperates with the strip slide groove; the window sash mounting top plate is arranged on the upper side of the window frame mounting base plate, the middle section front side of the window sash mounting top plate is connected to a support plate, the top surface position of the support plate is lower than the top surface of the window sash mounting top plate; the first connecting rod and the second connecting rod are arranged between the window frame mounting base plate and the window sash mounting top plate, the length of the second connecting rod is greater than the length of the first connecting rod degree; the first end of the first connecting rod is hinged to the first end of the window frame mounting base, and the second end of the first connecting rod is hinged to the first end of the support plate; the first end of the second connecting rod is hinged to the second end of the window frame mounting base, and the second end of the second connecting rod is hinged to the second end of the support plate; the third connecting rod is arranged between the first connecting rod and the second connecting rod, the length of the third connecting rod is less than the length of the second connecting rod, the first end of the third connecting rod is hinged to the sliding member, the first end of the third connecting rod is between the first end of the first connecting rod and the first end of the second connecting rod, and the second end of the third connecting rod is hinged to the middle section of the second connecting rod.

[0006] The above-mentioned high-load-bearing window sash hinge is suitable for installing outward-opening window structures with relatively heavy window sashes. During installation, the window frame mounting base of the high-load-bearing window sash hinge can be installed on the rear side of the inner side of the window frame of the outward-opening window structure (i.e., the inner side of the window frame that faces the indoor environment). The window sash is installed on the window sash mounting top plate of the high-load-bearing window sash hinge, with the support plate located below the window sash to support it. (Because the support plate is located on one side of the window sash mounting top plate and its top surface is lower than the top surface of the window sash mounting top plate, interference with the installation of the window sash is avoided at the hinged joint, allowing the window sash to be smoothly installed on the window sash mounting top plate.)

[0007] When the user opens the window sash toward the outside, the window sash mounting top plate swings under the drive of the window sash, and then drives the first connecting rod, the second connecting rod and the third connecting rod to swing relative to the window frame mounting bottom plate (at this time, the sliding member slides relatively along the strip slide groove). Since the window frame mounting bottom plate is installed on the side of the window frame of the outward-opening window structure close to the interior, the first connecting rod and the second connecting rod are located between the window frame mounting bottom plate and the window sash mounting top plate, and the third connecting rod is located between the first connecting rod and the second connecting rod. Therefore, the window frame gravity borne by the window sash mounting top plate can be dispersed to the window frame mounting bottom plate through the first connecting rod, the second connecting rod and the third connecting rod, and the support plate is located under the window sash and supports the window sash, which can support the window sash, so that the high-load-bearing window sash hinge has better load-bearing capacity and can support high-weight window sashes, thereby solving the problem of excessive force concentration on the window sash hinge, and then solving the problem of excessive local stress on the window sash hinge, improving the service life of the window sash hinge, lowering the material requirements for the high-load-bearing window sash hinge, and reducing production costs.

[0008] As a preferred embodiment of the present invention, a first end portion of the window frame mounting base plate is provided with a snap-fit ​​post, and a first end portion of the window sash mounting top plate is provided with a snap-fit ​​interface that snaps into engagement with the snap-fit ​​post. When the user closes the window sash toward the interior, the snap-fit ​​interface on the window sash mounting top plate snaps into engagement with the snap-fit ​​post on the window frame mounting base plate, thereby securing the closed window sash.

[0009] As a further preferred solution of the present invention, the card interface is arc-shaped, and the card interface matches the outer peripheral surface of the card post.

[0010] As a preferred solution of the present invention, the length of the window frame mounting base plate is 25-35 cm, and the width of the window frame mounting base plate is 20-40 cm.

[0011] As a preferred solution of the present invention, the length of the window sash mounting rod is 15-25 cm, and the length of the support plate is 4-10 cm.

[0012] As a preferred solution of the present invention, the length of the first connecting rod is 5-15 cm, the length of the second connecting rod is 15-25 cm, and the length of the third connecting rod is 5-15 cm.

[0013] As a preferred solution of the present invention, the distance between the hinge point between the first end of the first connecting rod and the window frame mounting base plate and the hinge point between the second end of the first connecting rod and the support plate is 75 mm±4 mm.

[0014] As a preferred embodiment of the present invention, a limiting post is provided on the middle section of the window frame mounting base plate. The limiting post is located between the strip-shaped slide groove and the first connecting rod and engages with the first end of the first connecting rod. With this structure, the limiting post can be used to limit the first end of the first connecting rod, thereby limiting the maximum swing angle of the first connecting rod around the window frame mounting base plate, thereby controlling the maximum opening and closing angle of the window sash mounting top plate.

[0015] As a preferred embodiment of the present invention, the window frame mounting base plate is provided with a plurality of first screw mounting holes sequentially distributed along its length, and the window sash mounting top plate is provided with a plurality of second screw mounting holes sequentially distributed along its length. The window frame mounting base plate can be mounted to the rear portion of the inner side of the window frame of the outward-opening window structure via the plurality of first screw mounting holes, and the window sash can be mounted to the window sash mounting top plate of the high-load-bearing window sash hinge via the plurality of second screw mounting holes.

[0016] A outward-opening window structure comprises a window frame, at least one window sash and at least one hinge group, the window sash being mounted on the inner side of the window frame through the hinge group, each hinge group comprising two hinges arranged side by side up and down, the two hinges being respectively located on the upper and lower sides of the window sash, and characterized in that: the hinge adopts the high-load-bearing window sash hinge, the window frame mounting base plate of the high-load-bearing window sash hinge is mounted on the rear side of the inner side of the window frame, the bottom and top of the window sash are respectively mounted on the window sash mounting top plates of the two high-load-bearing window sash hinges of the hinge group, the support plate of the high-load-bearing window sash hinge on the lower side of the hinge group is located below the window sash and supports the window sash, and the support plate of the high-load-bearing window sash hinge on the upper side of the hinge group is located above the window sash and presses the top of the window sash.

[0017] When the user opens the window sash toward the outside, the window sash mounting top plate swings driven by the window sash, and then drives the first connecting rod, the second connecting rod and the third connecting rod to swing relative to the window frame mounting bottom plate (at this time the sliding member slides relatively along the strip slide groove). Since the window frame mounting bottom plate is installed on the side of the window frame close to the interior of the room of the outward-opening window structure, the first connecting rod and the second connecting rod are located between the window frame mounting bottom plate and the window sash mounting top plate, and the third connecting rod is located between the first connecting rod and the second connecting rod. Therefore, the window frame gravity borne by the window sash mounting top plate can be dispersed to the window frame mounting bottom plate through the first connecting rod, the second connecting rod and the third connecting rod. Moreover, the support plate is located below the window sash and supports the window sash, which can support the window sash, so that the high-load-bearing window sash hinge has better load-bearing capacity, thereby solving the problem of excessive force concentration on the window sash hinge, and then solving the problem of excessive local stress on the window sash hinge, thereby improving the service life of the window sash hinge, lowering the material requirements for the high-load-bearing window sash hinge, and reducing production costs.

[0018] The above-mentioned window frame can adopt existing technology, and its specific structure can refer to the overall turning frame in the Chinese utility model patent specification with authorization announcement number "CN212105564U" and patent name "A transfer structure for outward-opening windows".

[0019] In this specification, the front and the rear are respectively: the side of the frame of the outward-opening window structure close to the outside of the window is the front, and the side of the frame of the outward-opening window structure close to the room is the rear.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] This high-load-bearing window sash hinge is suitable for the installation of outward-opening window structures with high-weight window sashes. The window frame gravity borne by the window sash mounting top plate can be dispersed to the window frame mounting bottom plate through the first connecting rod, the second connecting rod, and the third connecting rod, thereby solving the problem of excessive force concentration on the window sash hinge, and then solving the problem of excessive local stress on the window sash hinge. It has a high load-bearing capacity, which increases the service life of the window sash hinge, and the material requirements for the high-load-bearing window sash hinge are reduced, thereby reducing production costs.
