Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, in particular to a load-bearing component of doors and windows. Background Art

[0002] Modern doors and windows are usually in the form of a door and window body with the side of the door and window frame hinged to the side of the door and window frame. When the door is opened, it is pulled open in a hinged manner. In this case, the weight of the door and window body falls entirely on the hinges that connect the two, which requires high strength of the hinges. Nowadays, in occasions such as sun rooms, heavier doors and windows are used. The supporting force of conventional hinges is not enough. If hidden hinges installed above and below the door and window are used, it will be even more difficult to support. To solve the above technical problems, the applicant has applied for a door and window load-bearing device (application number CN202421953205.7), which includes a first connecting member, a connecting rod, and a second connecting member. The first connecting member and the second connecting member are respectively connected to the door and window frame and the side of the door and window body. One end of the connecting rod is hinged to the first connecting member, and the other end is movably connected to the second connecting member. However, during the opening and closing process of doors and windows, the connecting rod is swung on the first connecting piece and will tilt up during the swinging process. After long-term use, the connecting rod is prone to bending and deformation, causing damage, which not only shortens the service life of the connecting rod but also affects the normal use of doors and windows. Therefore, based on the above problems, the applicant has made further improvements to the above technology. Utility Model Content

[0003] In view of the above problems, the utility model provides a load-bearing assembly for doors and windows with a simple and stable structure and increased service life.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a load-bearing component for doors and windows, comprising a mounting plate, a connecting seat and a transmission rod, wherein the mounting plate is located above the connecting seat and is used to support the transmission rod, and the transmission rod is used to support the connecting seat, and a connecting block is hingedly provided on the connecting seat, and the connecting seat rotates left and right relative to the connecting block along the direction of door and window opening and closing, and the hinged end of the connecting block is close to one end of the transmission rod, and the other end is provided with a through slot, and one end of the transmission rod is hinged to the mounting plate, and the other end passes through the through slot and is suspended in the through slot.

[0005] By adopting the above technical solution, when the doors and windows are in the fully closed state, the connecting seat and the mounting plate are in the same vertical plane. Preferably, the mounting plate is fixedly installed at the side position of the doors and windows main body, and the connecting seat is fixedly installed at the side position of the doors and windows frame. The mounting plate is located above the connecting seat and is used to support the connecting seat. After all parts are installed, the connecting seat installed on the doors and windows frame will conduct the weight of the doors and windows frame to the mounting plate through the transmission rod. In this way, the doors and windows frame will be suspended by the transmission rod, sharing the pressure on the hinge and increasing the load-bearing capacity of the doors and windows. The structure is simple and stable. With such a setting, when the doors and windows are opened, the connecting seat installed on the doors and windows frame will move as the doors and windows are opened. When the connecting seat moves, the transmission rod is driven to swing along the direction of the connecting seat.

Detailed implementation manners

[0043] This specific embodiment is only an interpretation of the present utility model and is not a limitation thereof. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the Patent Law.

[0044] See the appendix Figure 1-8, A load-bearing component of a door and window disclosed by the present utility model includes a mounting plate 1, a connecting seat 2, and a transmission rod 3. The mounting plate 1 is located above the connecting seat 2 and is used to support the transmission rod 3. The transmission rod 3 is used to support the connecting seat 2. A connecting block 4 is hingedly arranged on the connecting seat 2. The connecting seat 2 rotates left and right along the door and window opening and closing direction relative to the connecting block 4. One end of the hinged end of the connecting block 4 is close to one end of the transmission rod 3, and a through groove 5 is opened at the other end. One end of the transmission rod 4 is hinged to the mounting plate 1, and the other end passes through the through groove 5 and is suspended in the through groove 5. When the door and window is in the fully closed state, the connecting seat 2 and the mounting plate 1 are in the same vertical plane. Preferably, the mounting plate 1 is fixedly installed at the side position of the door and window main body 27, and the connecting seat 2 is fixedly installed at the side position of the door and window frame 28. The mounting plate 1 is located above the connecting seat 2 and is used to support the connecting seat 2. After all parts are installed, the connecting seat 2 installed on the door and window frame 28 will conduct the weight of the door and window frame 28 to the mounting plate 1 through the transmission rod 3. In this way, the door and window frame 28 will be suspended by the transmission rod 3, sharing the pressure on the hinge and increasing the load-bearing capacity of the door and window. The structure is simple and stable. With such a setting, when the door and window is opened, the connecting seat 2 installed on the door and window frame 28 will move as the door and window is opened. When the connecting seat 2 moves, the transmission rod 3 is driven to swing along the direction of the connecting seat 2. When the opening angle between the door and window frame 28 and the door and window main body 27 is greater than 90°, the connecting seat 2 will rotate relative to the connecting block 4 along the door and window opening direction. The connecting block 4 is used to compensate for the swinging range of the transmission rod 3, completing the opening of the door and window frame 28 and the door and window main body 27 from 0° to 180°, avoiding the bending and deformation of the transmission rod 3 during the opening and closing of the door and window, causing damage, ensuring the normal use of the door and window, and at the same time improving the service life of the transmission rod 3 and further improving the reliability of the structure. Of course, the installation positions of the mounting plate 1 and the connecting seat 2 can also be interchanged, that is, the mounting plate 1 is installed on the side of the door and window frame 28, and the connecting seat 2 is installed on the side of the door frame main body 27, with strong versatility.

[0045] In this embodiment, it is further set that: an installation groove 6 for accommodating the connecting block 4 is opened on the connecting seat 2. An installation hole 7 is arranged on the hinged end of the connecting block 4. A connecting shaft 8 is arranged at the position of the installation groove 6 corresponding to the installation hole 7. The connecting block 4 is sleeved on the outer periphery of the connecting shaft 8 through the installation hole 7. The connecting block 4 is arranged in the installation groove 6 and rotates relative to the connecting seat 2 through the cooperation of the connecting shaft 8 and the installation hole 7. The setting of the installation groove 6 is used to position and install the connecting block 4. At the same time, when the connecting block 4 rotates relative to the connecting seat 2, it plays a guiding role, making the relative rotation of the two more stable and improving the reliability of the structure.

[0046] In this embodiment, further settings are made as follows: The connecting shaft 8 includes a main shaft 801 and a cap 802. A first connecting hole 9 is provided on one side above the installation groove 6 and corresponding to the position of the installation hole 7. The cap 802 is arranged at one end of the main shaft 801, and the other end of the main shaft 801 passes through the first connecting hole 9 and the installation hole 7 in sequence. During installation, first insert the connecting block 4 into the position of the installation groove 6, and make the position of the installation hole 7 of the connecting block 4 correspond to the position of the first connecting hole 9. After correspondence, insert the main shaft 801 along the upper side of the installation groove 6 towards the connecting block 4, so that the connecting block 4 is sleeved on the outer periphery of the main shaft 801. After the main shaft 801 is inserted, fix the position of the main shaft 801 through the cap 802. The structure is stable and the disassembly and assembly are convenient.

[0047] In this embodiment, further settings are made as follows: A second connecting hole 10 coaxial with the first connecting hole 9 is provided on one side below the installation groove 6. The other end of the main shaft 801 relative to the cap 802 passes through the first connecting hole 9, the installation hole 7, and the second connecting hole 10 in sequence. The position of the second connecting hole 10 further restricts the axial and radial positions of the other end of the main shaft 801 relative to the cap 802, making its structure more stable, and avoiding displacement damage to the position of the main shaft 801 caused by the swing of the transmission rod 3 when the doors and windows are opened and closed, which affects the normal use of the doors and windows. The main shaft 801 can be a screw or a dowel pin, and the front end head thereof can be arranged in a conical shape for convenient insertion. And a conical groove adapted to the front conical shape of the main shaft 801 is provided at the bottom of the second connecting hole 10 to further restrict the position of the main shaft 801 and avoid displacement, making the structure more stable.

[0048] In this embodiment, further settings are made as follows: An avoidance notch 11 for avoiding the transmission rod 3 is provided above the other end of the installation groove 6 relative to the connecting shaft 8. With the setting of the avoidance notch 11, when the opening and closing angle between the window and door frame 28 and the window and door body 27 is less than 90°, the transmission rod 3 will be located in the avoidance notch 11, reducing the volume of the connecting seat 2 and making the structure more compact.

[0049] In this embodiment, further settings are made as follows: A connecting rod 12 is provided between the mounting plate 1 and the transmission rod 3. A sliding long hole 13 is longitudinally provided on the mounting plate 1. The hinge shaft on the transmission rod 3 is located in the sliding long hole 13, and both ends of the connecting rod 12 are hinged to the transmission rod 3 and the mounting plate 1 respectively. The connecting rod 12 can pull the transmission rod 3 to increase the stability of the transmission rod 3, and after being connected to the connecting rod 12, one end of the transmission rod 3 will slide while being hinged in the sliding long hole 13, reducing the displacement of the end of the transmission rod 3 connected to the connecting seat 2 in the vertical direction during the swinging process, and keeping it as much as possible on the same horizontal plane, making the connection more stable.

[0050] This embodiment is further configured as follows: a T-shaped pin 14 is provided at one end of the transmission rod 3 facing the through slot 5, and the T-shaped pin 14 includes a head 1401 and a rod 1402. One end of the rod 1402 is connected to the transmission rod 3, and the other end passes through the through slot 5 and is connected to the head 1401. The outer diameter of the rod 1402 is smaller than the inner diameter of the through slot 5, and the outer diameter of the head 1401 is larger than the inner diameter of the through slot 5. The end of the transmission rod 3 will be provided with an assembly hole that is compatible with the rod portion 1402 of the T-shaped pin 14. During installation, the end of the transmission rod 3 is aligned with the position of the through slot 5, and then the rod portion 1402 is inserted into the assembly hole along the lower end of the through slot 5. The installation is convenient. After installation, the rod portion 1402 is placed in the through slot 5, and its head 1401 will be stuck at the bottom of the through slot 5, preventing the transmission rod 3 from being out of the position of the through slot 5, and the structure is more stable. The transmission rod 3 is buckled on the connecting block 4 through the T-shaped pin 14, so that the weight of the door and window frame 28 will be suspended at the position of the T-shaped pin 14 by the connecting block 4, and the structure is more stable and easy to install.

[0051] This embodiment further provides that the head portion 1401 is arc-shaped at one end facing the rod portion 1402. When the transmission rod 3 is positioned at the through slot 5 and swings to open or close the door or window, the head portion 1401 is arc-shaped at one end facing the rod portion 1402, thereby reducing the contact area between the arc surface and the through slot 5, effectively preventing friction and wear and extending the service life.

[0052] This embodiment further provides that the longitudinal cross-section of the through-slot 5 is trapezoidal. The transmission rod 3 is suspended in the through-slot 5. When the door or window is opened or closed, the longitudinal cross-section of the through-slot 5 is trapezoidal, which increases the space for the transmission rod 3 to swing, prevents the transmission rod 3 from being rigidly broken, and improves its service life.

[0053] This embodiment further provides that the connecting base 2 includes a mounting member 201 and a movable member 202, wherein the mounting member 201 and the movable member 202 are slidably connected, the mounting groove 6 is located on the movable member 202, and the mounting member 201 is provided with an adjusting member 203 for adjusting the position of the movable member 202 on the mounting member 201. The mounting member 201 can be fixed to the door and window frame 28 via a plurality of bolts, and the movable member 202 changes its position on the mounting member 201 via the adjusting member 203, thereby adjusting the tightness between the transmission rod 3 and the movable member 202, resulting in a reliable structure and convenient adjustment.

[0054] In this embodiment, it is further provided that: a plugging slot 15 is arranged on one side of the moving member 202 corresponding to the mounting member 201, a plug connector 16 adapted to the plugging slot 15 is arranged on the mounting member 201, and the plug connector 16 moves up and down along the direction of the plugging slot 15 through an adjusting member 203.
