Description

Technical Field

[0001] This utility model relates to the field of door and window hinge technology, and in particular to a hanging groove type door and window hinge bracket and its door and window hinge. Background Technology

[0002] The hinge arm (also called the support arm) of a door and window hinge is usually installed on the profile of the bottom frame of the window sash. It is used to support the weight of the entire window sash and transmit the movement of the window sash to other parts of the hinge, so as to realize the functions of opening, closing and fixing the door and window.

[0003] Currently, common hinge support structures are typically installed by directly inserting the hinge into the corresponding T-slot in the bottom frame profile of the window sash and securing it with screws. However, due to differences in the structural design of various door and window hinges, some hinges require special hinge support structures to adapt to installation needs. For example, the front end of some hinge support arms needs to be recessed so that it can be positioned below the T-slot opening to meet specific installation or functional requirements.

[0004] However, this recessed bracket design has certain drawbacks. Because the front half of the bracket is suspended in the air and lacks effective support, it is prone to bending and deformation when bearing the weight of the window sash, thus reducing the overall structural strength and load-bearing capacity of the bracket. Especially during long-term use, this imbalance of forces accelerates fatigue damage to the bracket, consequently affecting the overall performance and lifespan of the door and window hinges. Furthermore, traditional bracket structures may suffer from inaccurate positioning and loosening during installation, affecting the stability and safety of doors and windows.

[0005] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a hanging groove type door and window hinge bracket and its door and window hinge that are stable under force, simple in structure, high in strength and easy to install.

[0007] This utility model can be achieved through the following technical solutions:

[0008] To solve the above-mentioned technical problems, this utility model provides a hanging groove type door and window hinge bracket, including a bracket body that can be inserted into a T-shaped groove of a corresponding profile. The front part of the bracket body is provided with a recessed plate integrally connected thereto. The two sides of the top surface of the recessed plate are respectively provided with reinforcing structures, wherein the reinforcing structure on one side is a suspension part, and the reinforcing structure on the other side is a limiting part or also a suspension part. The suspension part includes an upwardly protruding first protrusion, and the outer side of the first protrusion is provided with a suspension plate that can be suspended on one side of the T-shaped groove of the corresponding profile. The limiting part includes an upwardly protruding second protrusion, and the outer side of the second protrusion is provided with a positioning surface that can abut against the other side of the T-shaped groove of the corresponding profile. The end of the recessed plate is also provided with a limiting plate that extends upward and can block the end face of the corresponding profile. The suspension part, the limiting part, and the limiting plate are all integrally formed by stamping or bending the recessed plate.

[0009] To further address the technical problems to be solved by this utility model, this utility model provides a slotted door and window hinge support arm in which the top surface of the recessed plate is lower than the lower surface of the support arm body.

[0010] In order to further solve the technical problem to be solved by this utility model, the present utility model provides a connecting transition part at the connection between the bracket body and the sinking plate. The connecting transition part includes a bottom wall and a side wall. The bottom wall is an arc-shaped head located at the rear end of the sinking plate and extending backward. The side wall extends smoothly upward from the periphery of the arc-shaped head to the front end of the bracket body.

[0011] In order to further solve the technical problems to be solved by this utility model, the bottom wall of the grooved door and window hinge support arm provided by this utility model is provided with a raised or grooved reinforcing rib.

[0012] In order to further solve the technical problem to be solved by this utility model, the present utility model provides a grooved door and window hinge support arm, wherein the two sides of the connecting transition part are provided with avoidance notches to avoid the edge of the corresponding profile T-shaped groove.

[0013] This utility model can also be achieved through the following technical solutions:

[0014] A door and window hinge includes a base plate, a short arm, a long arm, and a mounting bracket of the aforementioned slotted door and window hinge. One end of the short arm is rotatably connected to the base plate, and the other end of the short arm is rotatably connected to the front of the bracket. One end of the long arm is rotatably connected to the rear of the bracket, and the other end of the long arm is rotatably connected to a slider. The slider is slidably connected to the base plate along the length of the base plate.

[0015] To further address the technical problems to be solved by this utility model, a door and window hinge provided by this utility model also includes a reinforcing arm, one end of which is rotatably connected to the base plate, and the other end of which is rotatably connected to the middle of the long arm.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The reinforcing structure on both sides of the top surface of the recessed plate in this utility model achieves stable suspension by setting a suspension part on one side and utilizing the cooperation between the suspension plate and the T-shaped groove of the profile; a limiting part or another suspension part is set on the other side, wherein the limiting part uses the positioning surface to abut against the edge of the T-shaped groove to restrict the torsion of the support arm. This unique reinforcing structure design effectively improves the overall stability and load-bearing capacity of the support arm, avoids deformation or damage caused by uneven stress, and significantly improves the service life of the support arm. At the same time, the support arm structure is simple, and can be formed entirely by integral stamping or bending, with fewer manufacturing processes and lower cost.

[0018] 2. In this utility model, the connection transition between the support arm body and the sunken plate adopts a combination of an arc-shaped bottom wall and an inclined side wall, achieving a smooth stress transition and reducing stress concentration. Simultaneously, the reinforcing ribs on the bottom wall further enhance the strength and rigidity of the connection transition. This connection transition ensures that the support arm can evenly transfer the force to the support arm body when bearing load, thereby improving the overall structural strength and reliability of the support arm.

[0023] Figure 4 This is a three-dimensional structural diagram of the support arm in Embodiment 2. Detailed Implementation

[0024] 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.

[0025] Example 1:

[0026] like Figures 2 to 3 As shown, this embodiment provides a slotted door and window hinge bracket, which mainly includes a bracket body 1 and a recessed plate 2. The bracket body 1 can be inserted into the T-shaped slot of the door and window profile, thereby realizing the connection and fixation between the bracket and the profile (of course, screws are also used for fastening). The recessed plate 2 is integrally connected to the front of the bracket body 1 and is located at the lower front of the bracket body 1.

[0027] To enhance the structural strength and stability of the sunken plate 2, this embodiment provides reinforcing structures on both sides of the top surface of the sunken plate 2. The reinforcing structure on one side is the suspension part 3, while the reinforcing structure on the other side is the limiting part 4.

[0028] The suspension part 3 includes an upwardly protruding first protrusion 31 and a suspension plate 32. The first protrusion 31 is preferably an arch bridge-shaped structure, thereby improving its own strength and rigidity. The suspension plate 32 is disposed on the outer side of the first protrusion 31, and its shape and size are designed to fit with one side of the T-slot of the door and window profile, thereby realizing the suspension function and reliably fixing the bracket to the profile.

[0029] The limiting part 4 includes an upwardly protruding second protrusion 41. The second protrusion 41 can take various shapes, such as an arch or a protrusion. The outer surface of the second protrusion 41 is a positioning surface 42, the position and angle of which are designed to abut against the other edge of the T-slot of the door and window profile, thereby limiting the torsion of the recessed plate 2 at the front end of the support arm, ensuring the stability of the support arm under force, and avoiding deformation or damage caused by uneven force.

[0030] Furthermore, to further improve the overall stability of the support arm, this embodiment also provides an upwardly extending limiting plate 5 at the end of the recessed plate 2. The limiting plate 5 can abut against the end face of the door and window profile, thereby restricting the horizontal movement of the support arm and improving the positioning accuracy and reliability of the support arm.

[0031] To simplify the production process and reduce manufacturing costs, this embodiment preferably uses an integral stamping or bending method to manufacture the suspension part 3, the limiting part 4, and the limiting plate 5, so that they form an integral structure with the sinking plate 2, avoiding the use of welding or bolt connections, thereby reducing the number of parts and assembly steps and improving production efficiency.

[0032] In order to enable the bracket to better adapt to the structure of the door and window profiles, in this embodiment, the top surface of the recessed plate 2 is lower than the lower surface of the bracket body 1, thereby providing sufficient space for the installation of other components.

[0033] To improve the strength and rigidity of the connection between the support arm body 1 and the recessed plate 2, this embodiment also provides a connection transition section 6 between them. The connection transition section 6 includes a bottom wall 61 and a side wall 62. The bottom wall 61 is located at the rear end of the recessed plate 2, and the bottom wall 61 is preferably a rearwardly extending arc-shaped head structure (that is, the boundary line between the rear end of the bottom wall 61 and the front end of the side wall 62 is arc-shaped or U-shaped). The side wall 62 extends smoothly upward from the periphery of the arc-shaped head to the front end of the support arm body 1, thereby uniformly transferring the force of the recessed plate 2 to the support arm body 1. This structure can reduce stress concentration and increase structural strength.

[0034] To further improve the strength of the connecting transition portion 6, this embodiment may also provide a raised or recessed reinforcing rib 611 on the bottom wall 61.

[0035] To avoid interference between the support arm and the profile, this embodiment also provides clearance notches 63 on both sides of the connecting transition portion 6. The clearance notches 63 can avoid the edges on both sides of the T-groove of the door and window profile, thereby ensuring that the support arm can be smoothly inserted into the T-groove of the profile.

[0036] In this embodiment, the design of the suspension plate 32 of the suspension part 3 holding the profile, the positioning surface 42 of the limiting part 4 restricting the torsion of the sinking plate 2 at the front end of the support arm, and the limiting plate 5 restricting the horizontal movement of the support arm effectively ensures the stability of the support arm under force, improving its structural strength and service life. At the same time, this embodiment uses an integral molding method to manufacture the various components of the support arm, which simplifies the production process and reduces manufacturing costs.

[0037] Example 2:

[0038] like Figure 4 As shown, the difference between this embodiment and the first embodiment described above is that the reinforcing structures on both sides of the top surface of the sunken plate 2 are both suspension parts 3. That is to say, in this embodiment, suspension structures are used on both sides of the support arm to fix the support arm.

[0039] More specifically, in this embodiment, the suspension parts 3 on both sides are designed in a figure-7 shape, which allows them to better fit with the edges of the T-grooves of the door and window profiles, improving the reliability and stability of the suspension. Of course, the suspension parts 3 can also adopt other shapes, such as L-shape, U-shape, etc., as long as the suspension function can be achieved.

[0040] This embodiment is suitable for applications requiring high stability and load-bearing capacity of the support arm. By employing a dual-side suspension structure, the overall strength and rigidity of the support arm can be effectively improved, enabling it to withstand greater loads and exhibit better resistance to deformation.

[0041] Example 3:

[0042] like Figure 1As shown, this embodiment also discloses a door and window hinge, which mainly includes a base plate 7, a short arm 8, a long arm 9, and the hanging groove type door and window hinge support arm in the above embodiment one or embodiment two.

[0043] One end of the short arm 8 is fixed to the base plate 7 via a rotatable connection, while the other end is fixed to the front of the support arm (i.e., the recessed plate 2) via a rotatable connection. One end of the long arm 9 is fixed to the rear of the support arm (i.e., the support arm body 1) via a rotatable connection, while the other end is connected to a slider via a rotatable connection. The slider slides along the length of the base plate 7, thereby realizing the opening and closing functions of the door and window.

[0044] To further improve the stability and load-bearing capacity of the door and window hinges, this embodiment may also include a reinforcing arm 91. One end of the reinforcing arm 91 is fixed to the base plate 7 by a rotatable connection, while the other end is fixed to the middle of the long arm 9 by a rotatable connection. Through the connection of the reinforcing arm 91, the load borne by the long arm 9 can be effectively distributed, improving its resistance to deformation.

[0045] The door and window hinge structure in this embodiment is simple and compact, and easy to install and maintain. By adopting the hanging groove type door and window hinge support arm as described in Embodiment 1 or Embodiment 2, the overall performance and service life of the door and window hinge can be effectively improved.
