Description

Technical Field

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

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. Concealed hinges for windows are used to connect the window sash and the window frame.

[0003] Chinese patent document CN216277428U discloses an adjustable casement door and window hinge, including a fixed plate, a driving rod, a driven rod, a secondary connecting rod, and a window sash linkage rod. The window sash linkage rod includes a lower mounting body that links with the bottom edge of the window sash and a side mounting body that links with the side edge of the window sash. The side mounting body is characterized by having a sealing adjustment mechanism, a lateral position adjustment mechanism that adjusts the left and right gap values ​​of the window sash at the end of the lower mounting body, and a vertical position adjustment mechanism that adjusts the vertical position of the window sash.

[0004] The sliding groove used for limiting is located on the fixed plate, which is mounted on the door and window frame. Therefore, the position of the sliding groove must be separated from the door and window frame to allow the moving parts to move. This will lead to unstable installation. In addition, the sliding groove is located at the end of the connection of each link, where the lever force is the greatest. The pressure of the door and window is released at this position, resulting in poor load-bearing capacity of the hinge. Utility Model Content

[0005] In summary, to overcome the shortcomings of the existing technology, this utility model provides a more stable door and window hinge with stronger load-bearing capacity.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a door and window hinge, comprising a fixed base, a first connecting member, a second connecting member, and a movable base, wherein the two ends of the first connecting member are movably connected to the fixed base and the movable base respectively, and the two ends of the second connecting member are movably connected to the fixed base and the movable base respectively, wherein the first connecting member is provided with a sliding groove, and the second connecting member is provided with a sliding block adapted to the sliding groove at the position of the sliding groove.

[0007] With this configuration, the fixed seat connects to the door and window frame, and the movable seat connects to the door and window body. When the door and window are opened and closed, the first and second connecting parts move between them. The sliding block works with the sliding groove to limit the opening angle of the door and window body. Unlike conventional models, the sliding block and sliding groove in this structure are not located on the fixed seat but on the first connecting part. In this way, the connection between the first connecting part and the fixed part no longer bears the function of limiting movement, but only needs to provide its normal movement function. The load-bearing capacity is stronger and more stable. The sliding block is not located at the end. The force on the second connecting part and the first connecting part only occurs on their mating end surfaces. Therefore, the sliding block itself, which only fits on the side of the sliding groove, does not become the main load-bearing part. It only bears the function of limiting movement and is not affected by the weight of the door and window body, making it more stable.

[0008] Furthermore, it also includes a third connector, with both ends of the second connector hinged to the fixed base and one end of the third connector, respectively, and the other end of the third connector hinged to the movable base, and both ends of the first connector hinged to the fixed base and the movable base, respectively.

[0009] With this configuration, the second connector and the movable part do not need to be connected by a movable connection after the third connector is installed. The ends of the three connectors are all connected to each other by hinges, meaning that the connection position can only rotate. This makes the overall structure more stable and has a stronger load-bearing capacity.

[0010] Furthermore, both the first connector and the third connector are located between the second connector and the movable seat.

[0011] With this configuration, the sliding block on the second connector will face upwards, allowing for a more direct view of the sliding groove and facilitating maintenance and adjustments.

[0012] Furthermore, a bent connector is provided at the hinge position between the first connector and the fixed base.

[0013] With this configuration, the first connector can be directly connected to the mounting base without the aid of gaskets or other parts while positioned above the second connector, resulting in a more stable structure.

[0014] Furthermore, a partition is provided between the second connector and the first connector.

[0015] With this design, the partition can separate the second connector from the first connector, preventing them from coming into direct contact. Both connectors can use materials with higher load-bearing capacity, while the partition can use a more wear-resistant material with less friction, making the opening and closing of doors and windows smoother.

[0016] Furthermore, the partition plate is provided with clearance holes that are adapted to the sliding block.

[0017] With this configuration, the partition can be fitted onto the sliding block, making it more stable and preventing it from sliding during the opening and closing of doors and windows. This also allows for more comprehensive coverage of the contact area between the first and second connecting parts.

[0018] Furthermore, the two sides of the partition are bent toward the direction of the second connector.

[0019] With this design, the bent partition will form a U-shape that wraps around the second connector. In conjunction with the clearance hole, the partition will not slide or rotate, making the structure more stable.

[0020] Furthermore, the sliding groove restricts the movement of the sliding block on the fixed base.

[0021] With this configuration, factors such as the rotation radius can be controlled to ensure that the sliding block is always directly above the fixed seat. In this way, even if the second connecting part is subjected to excessive force and deforms, the deformation will only occur outside the fixed seat and will not affect the sliding block, which will always remain vertically upward.

[0022] Furthermore, the sliding groove is a strip-shaped hole, and the sliding block is cylindrical.

[0023] With this configuration, the cylindrical sliding block and the strip hole cooperate to limit the structure, which is simple and the movement is stable. The first and second connecting parts are already stably connected and will not move in the vertical direction. Therefore, the sliding block does not need to be set with a fastening structure to the sliding groove. The top surface of the sliding block can be lower than the top surface of the sliding groove to achieve the limiting effect. The sliding block can be connected to the second connecting part by conventional methods such as riveting, welding, and threaded connection using cylindrical parts.

[0024] Furthermore, a wear-resistant pad is provided at the connection point between the second connector and the fixed base.

[0025] With this configuration, the hinge position of the second connecting part, which is mainly subjected to rotational force, can be fitted with a wear-resistant shim, making its rotation process smoother and more durable. Attached Figure Description

[0032] Referring to the accompanying drawings, this utility model provides the following technical solution: a door and window hinge, including a fixed base 1, a first connecting member 2, a second connecting member 3, and a movable base 4. The two ends of the first connecting member 2 are movably connected to the fixed base 1 and the movable base 4, respectively. The two ends of the second connecting member 3 are movably connected to the fixed base 1 and the movable base 4, respectively. The first connecting member 2 is provided with a sliding groove 201, and the second connecting member 3 is provided with a sliding block 301 adapted to the sliding groove 201.

[0033] With this configuration, the fixed seat 1 is connected to the door and window frame, and the movable seat 4 is connected to the door and window body. When the door and window are opened and closed, the first connecting piece 2 and the second connecting piece 3 will move between them. The sliding block 301 will cooperate with the sliding groove 201 to limit the opening angle of the door and window body. Unlike conventional models, the sliding block 301 and the sliding groove 201 in this structure are not located on the fixed seat 1 but on the first connecting piece 2. In this way, the connection position between the first connecting piece 2 and the fixed piece no longer bears the role of limiting, but only needs to provide its normal movement function. The load-bearing capacity is stronger and more stable. The sliding block 301 is not located at the end. The force on the second connecting piece 3 and the first connecting piece 2 only occurs on their mating end surfaces. Therefore, the sliding block 301, which only fits on the side between the sliding groove 201, will not become the main load-bearing part. It only bears the role of limiting and will not be affected by the weight of the door and window body, making it more stable.

[0034] In a preferred embodiment, the third connector 5 is further included. The two ends of the second connector 3 are respectively hinged to the fixed base 1 and one end of the third connector 5, and the other end of the third connector 5 is hinged to the movable base 4. The two ends of the first connector 2 are respectively hinged to the fixed base 1 and the movable base 4.

[0035] With this configuration, after setting the third connector 5, the second connector 3 and the movable part do not need to be connected. The ends of the three connectors are all connected to each other in a hinged manner, that is, the connection position can only rotate, making the overall structure more stable and the load-bearing capacity stronger.

[0036] In this preferred embodiment, both the first connector 2 and the third connector 5 are located between the second connector 3 and the movable seat 4.

[0037] With this configuration, the sliding block 301 on the second connector 3 will face upwards, making it easier to see the condition of the sliding groove 201 and facilitating maintenance and adjustment.

[0038] In this preferred embodiment, a bent connector 202 is provided at the hinge position between the first connector 2 and the fixed base 1.

[0039] With this configuration, the first connector 2 can be directly connected to the fixed base 1 without the aid of gaskets or other parts while being located above the second connector 3, resulting in a more stable structure.

[0040] In this preferred embodiment, a partition 302 is provided between the second connector 3 and the first connector 2.

[0041] With this configuration, the partition 302 can separate the second connector 3 and the first connector 2, preventing them from coming into direct contact. Both can use materials with higher load-bearing capacity, while the partition 302 uses a more wear-resistant material with less friction, making the opening and closing process of the doors and windows smoother.

[0042] In this preferred embodiment, the partition 302 is provided with a clearance hole 3021 that is adapted to the sliding block 301.

[0043] With this configuration, the partition 302 can be fitted onto the sliding block 301, making it more stable and preventing it from sliding during the opening and closing of doors and windows. This also allows for more comprehensive coverage of the contact area between the first connector 2 and the second connector 3.

[0044] In this preferred embodiment, the two sides of the partition 302 are bent toward the direction of the second connector 3.

[0045] With this configuration, after bending, the partition 302 will form a U-shape that wraps around the second connector 3. In conjunction with the clearance hole 3021, the partition 302 will not slide or rotate, making the structure more stable.

[0046] In a preferred embodiment, the sliding groove 201 restricts the movement of the sliding block 301 on the fixed base 1.

[0047] With this configuration, factors such as the rotation radius can be controlled to ensure that the sliding block 301 is always directly above the fixed base 1. In this way, even if the second connecting piece 3 is subjected to excessive force and deforms, the deformation will only occur outside the fixed base 1 and will not affect the sliding block 301. The sliding block 301 will always be vertically upward.

[0048] In this preferred embodiment, the sliding groove 201 is a strip-shaped hole, and the sliding block 301 is cylindrical.

[0049] With this configuration, the cylindrical sliding block 301 and the strip hole cooperate to limit the structure, which is simple and the movement is stable. The first connecting piece 2 and the second connecting piece 3 are already stably connected and will not move in the vertical direction. Therefore, the sliding block 301 does not need to be set with a fastening structure to the sliding groove 201. The top surface of the sliding block 301 can be lower than the top surface of the sliding groove 201 to achieve the limiting effect. The sliding block 301 can be connected to the second connecting piece 3 by conventional methods such as riveting, welding, and threaded connection using cylindrical parts.

[0050] In this preferred embodiment, a wear-resistant pad 303 is provided at the connection position between the second connector 3 and the fixed base 1.

[0051] With this configuration, the hinge position of the second connecting piece 3, which is mainly subjected to force and rotation, is equipped with a wear-resistant pad 303, which makes its rotation process smoother and more durable.
