[0001] This utility model relates to the technical field of hinge devices, specifically a wind pressure and torque resistant hinge device for a ventilator. Background Technology
[0002] In the field of building ventilation, ventilators are crucial components for achieving indoor-outdoor air circulation. The stability of their hinge mechanisms and their wind pressure resistance directly affect the safety and reliability of ventilator use. Existing ventilator hinge mechanisms typically employ simple pivot connection structures. When the window sash is subjected to strong wind pressure, the torque generated by the wind pressure can easily cause the window sash to deform, open uncontrollably, or even be damaged, indicating insufficient wind pressure resistance. Furthermore, traditional hinge structures are mostly based on single-link transmission, lacking effective torque transmission and distribution mechanisms. Long-term use can easily lead to component wear due to concentrated stress, and they lack automatic reset functions, requiring manual operation to close the window sash, resulting in low convenience.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1-3 As shown, this utility model provides a wind-pressure-resistant torque hinge device for a window, including a window frame connecting seat 1 and a window sash connecting seat 2, as well as a rigid torque arm 3 and a sliding member 4. One end of the rigid torque arm 3 is rotatably connected to the window frame connecting seat 1 via a first rotating shaft 7, and the other end is provided with a longitudinally extending guide groove 5. The sliding member 4 is rotatably connected to the window sash connecting seat 2 via a second rotating shaft 8 and is slidably nested in the guide groove 5. The contact surface between the inner wall of the guide groove 5 and the sliding member 4 is a pressure-resistant bearing surface, which is used to transmit a reverse torque to the window frame connecting seat 1 when the window sash is subjected to wind pressure.
[0023] This embodiment mainly consists of core components such as window frame connecting seat 1, window sash connecting seat 2, rigid torque arm 3, and sliding component 4. These components work together to achieve wind pressure resistance and torque transmission functions.
[0024] When the window sash is subjected to external wind pressure, the wind pressure is transmitted through the window sash to the window sash connecting seat 2. The window sash connecting seat 2 drives the sliding member 4 to move via the second rotating shaft 8. Since the sliding member 4 is slidably nested in the guide groove 5 of the rigid torque arm 3, the sliding member 4 slides longitudinally within the guide groove 5. The contact surface between the inner wall of the guide groove 5 and the sliding member 4 is a pressure-resistant bearing surface. During the sliding process, the sliding member 4 transmits the force generated by the wind pressure to the pressure-resistant bearing surface. After the pressure-resistant bearing surface receives this force, it causes the rigid torque arm 3 to rotate around the first rotating shaft 7, thereby transmitting the reverse torque to the window frame connecting seat 1. This reverse torque is opposite in direction to the torque generated by the wind pressure on the window sash, offsetting part or all of the wind pressure torque, effectively resisting the effect of wind pressure on the window sash, and maintaining the stability of the window sash.
[0025] Furthermore, the rigid torque arm 3 has a U-shaped cross-section structure, with its two side walls recessed inward to form the guide groove 5. The sliding member 4 is a rectangular slider, which is clearance-fitted with the guide groove 5. The U-shaped cross-section structure of the rigid torque arm 3, with its two side walls recessed inward to form the guide groove 5, provides a stable sliding track for the sliding member 4. The rectangular slider 4, with its clearance fit to the guide groove 5, ensures both flexible sliding within the guide groove 5 and effective force transmission and bearing by the compressive load-bearing surface.
[0026] Through the design of rigid torque arm 3, sliding part 4 and pressure-resistant bearing surface, when the window sash is subjected to wind pressure, it can effectively transmit the reverse torque to the window frame connecting seat 1, offset the torque generated by the wind pressure, improve the stability of the window in strong wind environment, and avoid problems such as deformation, damage or uncontrolled opening of the window sash due to excessive wind pressure.
[0027] Furthermore, the guide groove 5 is provided with a limiting boss 10 at its end, which is used to limit the maximum displacement stroke of the slider 4. The limiting boss 10 at the end of the guide groove 5 can limit the maximum displacement stroke of the slider 4, prevent the slider 4 from sliding out of the guide groove 5, ensure that the device operates within the normal working range, and avoid device failure due to excessive sliding of the slider 4.
[0028] Furthermore, it also includes a preload spring 6 for applying an elastic preload force in the closing direction to the window sash. The preload spring 6 is a torsion spring. The preload spring 6 is provided with a first lever arm 9 and a second lever arm 13. One end of the first lever arm 9 is fixed to the rigid torque arm 3 near the first rotating shaft 7, and one end of the second lever arm 13 is connected to the sliding member 4.
[0029] A torsion spring is sleeved on the first rotating shaft 7, with its first lever arm 9 abutting against the window frame connecting seat 1 and its second lever arm 13 abutting against the rigid torque arm 3. When the window sash is opened, the preload spring 6 is torn by the rotation of the rigid torque arm 3, storing elastic potential energy and applying an elastic preload force in the closing direction to the window sash.
[0030] Furthermore, the preload spring 6 is sleeved on the first rotating shaft 7. The first lever arm 9 of the preload spring 6 abuts against the window frame connecting seat 1, and the second lever arm 13 abuts against the rigid torque arm 3. When the window sash is subjected to wind pressure, the elastic preload force of the preload spring 6 and the reverse torque transmitted by the rigid torque arm 3 work together to enhance the ability to resist wind pressure. When the wind pressure disappears, the preload spring 6 releases its elastic potential energy, causing the window sash to close automatically, thus achieving automatic reset of the window sash.
[0031] Furthermore, the surface of the pressure-bearing surface is provided with a wear-resistant coating, which is made of polytetrafluoroethylene (PTFE) or hard alloy. The PTFE or hard alloy wear-resistant coating on the surface of the pressure-bearing surface can reduce frictional loss between the sliding element 4 and the inner wall of the guide groove 5, extend the service life of the hinge device, and reduce maintenance costs.
[0032] Furthermore, a double-link anti-torsion structure is provided between the window frame connecting seat 1 and the window sash connecting seat 2. The double-link anti-torsion structure includes an auxiliary link, the two ends of which are respectively hinged to the window frame connecting seat 1 and the window sash connecting seat 2 via a third rotating shaft 11 and a fourth rotating shaft 12.
[0033] The system includes an auxiliary connecting rod, whose two ends are hinged to the window frame connecting seat 1 and the window sash connecting seat 2 via a third pivot 11 and a fourth pivot 12, respectively. When the window sash is subjected to wind pressure, this structure works in conjunction with the rigid torque arm 3 to further disperse and transmit torque, enhance the torsional stiffness and stability of the entire hinge device, reduce the stress on individual components, and improve the overall wind pressure resistance of the device.
[0034] Furthermore, both the window frame connecting seat 1 and the window sash connecting seat 2 are provided with elongated oval mounting slots for adjusting the hinge's installation position. These elongated oval mounting slots on the window frame connecting seat 1 and the window sash connecting seat 2 allow for a certain range of positional adjustment during hinge installation. By adjusting the installation position, the installation requirements of different windows can be accommodated, ensuring the accuracy and reliability of the hinge installation, enabling better cooperation among components, and fully utilizing the performance of the wind pressure torque-resistant hinge device.
[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
