Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a transmission device and a door / window. Background Technology

[0002] With the development of the door and window industry, traditional transmission devices often use bolts, threaded holes, or die-cast connecting columns to connect the transmission bar and transmission components. While these traditional methods can achieve the transmission connection function to a certain extent, they suffer from problems such as unstable transmission, poor control precision, and susceptibility to breakage or fatigue damage. Especially under high load or frequent operation conditions, traditional materials and connection methods often experience instantaneous breakage, affecting the safety and service life of doors and windows. Therefore, a new design solution is urgently needed that can improve the reliability and durability of the transmission system while ensuring stability. Utility Model Content

[0038] See Figures 1 to 11 As shown, this utility model embodiment provides a transmission device, including: a transmission bar 1 and a stamped column 2 connected to the transmission bar 1. The stamped column 2 and the transmission bar 1 are integrally formed and are used to connect the transmission component 3.

[0039] Specifically, the transmission device of this utility model is applied in the field of doors and windows. The transmission component 3 includes a profile 31 installed on the door frame and a transmission rod 32 slidably connected to the profile 31. The transmission rod 32 drives the locking point of the door and window and cooperates with the lock seat of the door and window to realize the opening and closing of the door and window. The transmission rod 32 is provided with a connecting hole (not shown in the figure), and the stamping column 2 extends into and connects to the connecting hole. When the transmission bar 1 of the transmission device drives the stamping column 2 to move, since the stamping column 2 is connected to the transmission rod 32, the transmission rod 32 will slide on the profile 31. The sliding of the transmission rod 32 drives the locking point of the door and window to move, and then cooperates with the lock seat to realize the opening or closing of the door and window. This embodiment adopts a structural design in which the stamping column 2 and the transmission bar 1 are integrally formed, combining the stamping column 2 and the transmission bar 1 into one, providing a more stable and reliable transmission connection method. Due to the gradual deformation characteristics of the stamped column 2, it will not break instantly when the load exceeds the design bearing limit, but will gradually deform until it tears, avoiding the brittle fracture problem that may occur in traditional die-cast or riveted parts. This structure not only improves safety but also enhances the stability during the transmission process, ensuring the reliability of power transmission from the transmission bar 1 to the transmission assembly 3. This makes the control of the transmission assembly 3 more precise and stable, further improving the safety of doors and windows.

[0040] See Figures 1 to 6 and Figures 8 to 11 As shown, in one specific embodiment, the transmission device further includes a housing 4, a rotating component 5, and a transmission component 6. The rotating component 5 and the transmission component 6 are installed inside the housing 4. The rotating component 5 is rotatably connected to the housing 4 and is also drively connected to the transmission component 6. The side of the transmission component 6 away from the rotating component 5 is also drively connected to the transmission bar 1.

[0041] Specifically, the housing 4 extends into and is installed within the profile 31, while the transmission bar 1 is located on the outside of the profile 31. By incorporating the rotating component 5 and the transmission component 6, more precise control and adjustment of power transmission can be achieved, ensuring a more stable and orderly power transmission process from external power input to the final door / window lock point, reducing malfunctions caused by poor power transmission. Simultaneously, by installing the rotating component 5 and the transmission component 6 within the housing 4, these components are protected from external environmental influences, extending their service life and reducing wear and damage. When it is necessary to drive the transmission bar 1 to move, external power is applied to the rotating component 5, causing it to rotate within the housing 4; the rotating component 5 transmits this rotational motion to the transmission component 6, and due to their transmission connection, the transmission component 6 moves accordingly based on the rotation of the rotating component 5; the transmission component 6 further transmits the received power to the transmission bar 1 located on the outside of the profile 31, thereby causing the transmission bar 1 and the stamping column 2 to move along the outside of the profile 31.

[0042] See Figures 5 to 6 and Figures 10 to 11 As shown, in a specific embodiment, the box body 4 includes a first back plate 41 and a second back plate 42. The first back plate 41 is connected to the second back plate 42. Both the first back plate 41 and the second back plate 42 are provided with a rotating hole 411. The rotating component 5 is rotatably connected to the rotating hole 411.

[0043] Specifically, the design of the rotating hole 411 on the back plate provides a clear positioning standard for the installation of the rotating component 5, enabling assembly workers to more accurately and conveniently install the rotating component 5 into the appropriate position inside the housing 4, reducing the debugging time and difficulty during the installation process, and improving the assembly efficiency of the entire transmission device. At the same time, this positioning installation method effectively ensures the accuracy of parameters such as the installation angle and position of the rotating component 5, avoiding subsequent transmission problems caused by installation errors. The rotating component 5, through the rotating connection at both ends within the rotating hole 411 on the back plate, has a stable fulcrum and reliable constraint during its rotation. Compared to a design without this double-sided positioning support, it can better resist external interference and the influence of centrifugal force generated during its own rotation, making the trajectory of the rotating component 5 more stable and precise. This ensures that the transmission component 6 connected to it receives stable and uniform power, improving the stability of power transmission throughout the entire transmission path and facilitating more precise control of the locking point. Furthermore, because the rotational force of the rotating component 5 is evenly distributed at the rotation holes 411 on the two back plates, the situation of excessive local force is reduced, thereby lowering the risk of wear between the rotating component 5 and the housing 4 and extending the service life of the components. At the same time, this stable structural design also makes the entire transmission device less prone to failures caused by loosening or displacement of the rotating component 5 during long-term use, improving the structural reliability of the entire transmission device and reducing the frequency of maintenance and component replacement.

[0044] In one specific embodiment, the box body 4 further includes a first buffer pad 43 and a second buffer pad 44 installed between the first back plate 41 and the second back plate 42. The first buffer pad 43 and the second buffer pad 44 are symmetrically arranged on both sides of the rotating member 5 and the transmission member 6. A limiting space (not shown in the figure) corresponding to the rotating member 5 is formed between the first buffer pad 43 and the second buffer pad 44, and an active space (not shown in the figure) corresponding to the transmission member 6 is also formed.

[0045] Specifically, the first buffer pad 43 and the second buffer pad 44 are symmetrically arranged on both sides of the rotating component 5 and the transmission component 6, mainly based on the needs of buffering and limiting. During mechanical transmission, the rotating component 5 and the transmission component 6 will generate vibration and impact forces during operation. The buffer pads are elastic and can absorb these vibrations and impact forces, playing a buffering role and preventing damage caused by rigid collisions or excessive vibrations between components. This protects the rotating component 5, the transmission component 6, and other connected components, maintaining their normal working condition. At the same time, the two buffer pads form a limiting space corresponding to the rotating component 5 and an active space corresponding to the transmission component 6, which limits the range of motion of the rotating component 5 and the transmission component 6. The limiting space ensures that the rotating component 5 rotates within a reasonable area, preventing it from excessively deviating or dislodging due to unexpected situations (such as being subjected to excessive external forces), ensuring the stability and safety of rotation; the active space provides a certain range for the movement of the transmission component 6, allowing it to meet the transmission function while being constrained within a suitable range, ensuring the accuracy of the transmission path. Furthermore, the presence of the buffer pads also serves as an isolation and protection mechanism. On the one hand, it can isolate external dust, moisture, and other impurities, reducing the entry of these factors that may affect the performance of components into the working areas of rotating parts 5 and transmission parts 6, keeping the internal environment relatively clean, which is conducive to extending the service life of components and maintaining stable transmission performance. On the other hand, the buffer pad can isolate the noise generated by rotating parts 5 and transmission parts 6 during operation to a certain extent, reducing the noise level generated by the entire transmission device during operation and improving the user experience. By installing a buffer pad between the first back plate 41 and the second back plate 42, and cleverly using the buffer pad to divide different functional spaces, the buffer and limiting functions of key components are completed within the limited internal space of the box 4, without occupying too much extra space. This makes the layout of each component more compact and reasonable, integrating with the entire transmission device and its overall structure, and enhancing the comprehensive performance of the transmission device without affecting the original transmission function.

[0046] More specifically, the limiting space is semi-circular, and the moving space is rectangular. The semi-circular limiting space precisely limits the rotation range of the rotating component 5, ensuring its rotation trajectory remains within a reasonable circular motion state. This avoids problems such as interference or damage to other components that might occur due to uncontrolled positioning of the rotating component 5, greatly improving the accuracy and stability of the rotating component 5's rotation and ensuring that the connected transmission component 6 receives stable and reliable power input. The rectangular moving space also precisely constrains the linear movement of the transmission component 6, ensuring it moves strictly according to the preset direction and range. This guarantees the accuracy of the transmission component 6 in transmitting power, reduces deviations in the power transmission direction, helps to more accurately control the locking point, and improves the operational precision of the entire transmission device. This specific spatial design makes full use of the limited space inside the housing 4, clearly and compactly dividing the moving areas of the rotating component 5 and the transmission component 6, avoiding situations such as idle space or crowded components caused by unreasonable spatial layout. Each component can operate in an orderly manner within its respective suitable space, resulting in a more compact and regular internal structure of the entire transmission device. This reduces the overall size of the transmission device, making it easier to install and arrange in applications such as doors and windows. It also facilitates better coordination and collaboration with other related components. Precise motion constraints on the rotating component 5 and the transmission component 6 reduce unnecessary friction and collisions between components, lowering wear rates and extending their service life. Simultaneously, improved motion regularity and stability reduce the probability of malfunctions during long-term use, enhancing the overall reliability of the transmission device, reducing the frequency of maintenance and component replacement, and lowering operating costs. It is understood that in other embodiments, the shapes of the limiting space and the active space can be adjusted according to different specifications and performance requirements of the rotating component 5 and the transmission component 6.

[0047] See Figures 5 to 7 As shown, in one specific embodiment, the transmission bar 1 is provided with a locking part 11 on the side close to the transmission member 6, and the side of the transmission member 6 away from the rotating member 5 is locked to the locking part 11.

[0048] Specifically, a robust mechanical connection is constructed by setting a snap-fit ​​part 11 on the side of the transmission bar 1 near the transmission component 6, and snapping the transmission component 6 away from the rotating component 5 with it. This snap-fit ​​structure forms a reliable connection between the two components, ensuring that the transmission component 6 and the transmission bar 1 do not easily separate during relative movement, thus guaranteeing their continuity as adjacent links in the transmission path and allowing power to be smoothly transmitted from the transmission component 6 to the transmission bar 1. Compared to other connection methods (such as simple fitting), the snap-fit ​​method maintains greater stability under tension, pressure, and vibration, meeting the requirement for long-term stable power transmission in the frequent opening and closing of doors and windows. It effectively converts the movement of the transmission component 6 into the corresponding movement of the transmission bar 1, enabling subsequent control of the locking point. Furthermore, compared to using complex connectors (such as bolts and nuts) or more precise transmission mating structures, the snap-fit ​​connection method is relatively simple, easy to implement, and easy to assemble. While ensuring the reliability of the transmission connection, it reduces the use of additional parts, making the connection between the transmission bar 1 and the transmission component 6 more compact. This helps the entire transmission device to achieve a reasonable layout in a limited space, and reduces the problems of increased cost, increased assembly difficulty and increased potential failure points caused by too many parts. It is in line with the overall transmission device's design concept of structural simplification and efficiency.

[0049] In one specific embodiment, the snap-fit ​​portion 11 is arranged perpendicular to the transmission direction of the transmission bar 1.

[0050] Specifically, there are two locking parts 11, which are locked onto both sides of the transmission component 6, forming a symmetrical connection structure. From a mechanical point of view, when the transmission component 6 transmits power to the transmission bar 1, the resulting force is evenly distributed on the two locking parts 11, making the transmission bar 1 more balanced and symmetrical in all directions. This avoids instability such as tilting or loosening of the connection due to excessive force on one side, greatly enhancing the stability of the connection between the transmission component 6 and the transmission bar 1, and ensuring the reliability of the connection structure during power transmission. This double-sided locking method is similar to applying uniform tension or pressure to both sides of an object to fix it. Compared with the design of a single locking part 11, it can better cope with various complex external forces (such as vibration, impact forces in different directions, etc.) generated during the frequent opening and closing of doors and windows. It meets the design requirements of high strength and high stability for key connection parts in mechanical transmission, ensuring that power can be continuously and stably transmitted from the transmission component 6 to the transmission bar 1. The two locking parts 11 on both sides of the transmission component 6 not only serve a connecting function but also provide precise positioning and guidance for the transmission component 6 relative to the transmission bar 1. During movement, the transmission component 6 is restricted by the locking parts 11 on both sides, allowing its movement trajectory to more accurately align with the transmission direction of the transmission bar 1. This reduces potential issues such as deviations in power transmission direction or reduced transmission efficiency caused by relative positional discrepancies. Consequently, the movement of the transmission component 6 can be more effectively converted into the corresponding movement of the transmission bar 1, improving the accuracy and stability of the entire transmission path and meeting the functional requirements for precise control of the locking point action.

[0051] See Figure 9 As shown, in one specific embodiment, the transmission member 6 includes a first transmission plate 61, a base plate 62 and a second transmission plate 63 connected in sequence. At least one side of the first transmission plate 61 and the second transmission plate 63 is formed with a snap-fit ​​groove 64, which snaps into the snap-fit ​​part 11.

[0052] Specifically, the first transmission plate 61, the base plate 62, and the second transmission plate 63 are connected in sequence in a П shape. The first transmission plate 61 is located close to the first back plate 41, the second transmission plate 63 is located close to the second back plate 42, and the base plate 62 is attached to the transmission bar 1. Both sides of the first transmission plate 61 and the second transmission plate 63 are provided with snap-fit ​​grooves 64, which snap-fit ​​into the snap-fit ​​part 11.

[0053] The П-shaped structure gives the transmission component 6 high structural stability, enabling it to better withstand various external forces during long-term power transmission, reducing the risk of component deformation and damage, and extending the service life of the transmission component 6. Simultaneously, the support of the two back plates and the secure connection with the transmission bar 1 further enhance this stability, allowing the entire transmission device to maintain normal operation even under frequent use (such as frequent opening and closing of doors and windows), reducing the probability of the entire transmission device failing due to a malfunction of the transmission component 6, and improving the durability and reliability of the entire transmission device. The close fit between the base plate 62 and the transmission bar 1 increases the contact area between them, facilitating a more even and sufficient transfer of power from the transmission component 6 to the transmission bar 1, reducing energy loss and directional deviation during power transmission, and improving the efficiency and accuracy of power transmission. Furthermore, the precise engagement of the two side locking slots 64 with the locking part 11 precisely constrains the relative position and movement of the transmission component 6 and the transmission bar 1, ensuring that the movement of the transmission component 6 can be accurately converted into the corresponding movement of the transmission bar 1. This makes the control of the locking point more precise, improving the accuracy and stability of the door and window opening and closing operations. This structural design of the transmission component 6, while meeting functional requirements, also achieves a reasonable and compact layout within the housing 4, making full use of limited space resources and avoiding space waste and interference between components. Moreover, its relatively regular shape and clear installation position requirements make the assembly process simpler and more intuitive. Assembly workers can more easily install it in the correct position and connect it with other components, improving the assembly efficiency of the entire transmission device and reducing assembly difficulty and potential failure risks caused by improper assembly.

[0054] Furthermore, the snap-fit ​​part 11 is L-shaped, and the snap-fit ​​groove 64 is rectangular.

[0055] Specifically, the L-shaped locking part 11 has unique geometric advantages. Its two mutually perpendicular sides can limit and constrain the locking groove 64 from different directions, making the connection between the transmission component 6 and the transmission bar 1 more robust and reliable. This effectively copes with various complex external forces generated during frequent operation of doors and windows, ensuring the stability of the connection during power transmission. The rectangular locking groove 64 and the L-shaped locking part 11 are mutually adapted, clearly defining the spatial range for accommodating the locking part 11. This provides a precise positioning and matching area for the locking part 11, ensuring that the locking part 11 is effectively constrained in all directions after being inserted into the locking groove 64. This ensures that the locking structure will not experience arbitrary displacement or shaking during power transmission, meeting the requirements for precise and stable connection of key connection parts in mechanical transmission. Furthermore, during power transmission, the force is transmitted from the transmission component 6 to the locking part 11 of the transmission bar 1 through the locking groove 64. The design of the L-shaped locking part 11 and the rectangular locking groove 64 allows the force to be evenly distributed across multiple contact surfaces, avoiding stress concentration at a certain point or in a certain local area. For example, when the transmission component 6 applies a pushing or pulling force to the transmission bar 1, the force is transmitted through the locking groove 64 and each contact surface of the locking part 11. Through the large contact area and reasonable geometric shape matching, the force is dispersed, reducing the possibility of component damage or connection failure due to excessive local force, ensuring the safety and effectiveness of power transmission, and helping to extend the service life of components and maintain the stable operation of the entire transmission device.

[0056] It is understood that in other embodiments, the shapes of the snap-fit ​​portion 11 and the snap-fit ​​groove 64 may be set to other shapes.

[0057] See Figures 5 to 6 and Figure 8 As shown, in one specific embodiment, the transmission device further includes a rotating shaft 7, the rotating component 5 is provided with a shaft hole 51, the transmission component 6 is provided with a transmission groove 65, the transmission groove 65 is provided in an elongated oval shape, and the rotating shaft 7 is movably connected to the shaft hole 51 and the transmission groove 65.

[0058] Specifically, by utilizing the cooperation between the rotating shaft 7, the shaft hole 51, and the transmission groove 65, the rotational motion of the rotating component 5 is successfully converted into the linear motion of the transmission component 6. This allows the entire transmission path to smoothly transition from external rotational power input to the linear motion output of the transmission bar 1, ensuring the continuity and rationality of the motion form during power transmission. This provides a foundation for precise control of the opening and closing of doors and windows, enhancing the functionality and practicality of the transmission device. This motion conversion method, achieved through the movable connection of the rotating shaft 7, gives the transmission device excellent flexibility, enabling it to adapt to different power input conditions and the actual requirements of opening and closing doors and windows. Whether it's manual operation with varying degrees of force or potential future adaptation to electric drives with different power levels, the transmission device can adjust the motion state of the transmission component 6 through the flexible movement of the rotating shaft 7 within the transmission groove 65, thereby ensuring the stable operation of the entire transmission device. This broadens the application range of the transmission device, allowing it to be used in various types of door and window systems with different usage scenarios. The relatively simple yet efficient transmission structure constructed using the rotating shaft 7 achieves motion conversion and power transmission functions while optimizing the internal spatial layout of the transmission device, making it more compact and reducing problems such as interference between components and installation difficulties caused by complex structures. Furthermore, the stable fit between the rotating shaft 7 and the shaft hole 51 and transmission groove 65, along with the rational design of the entire transmission structure, improves the reliability of the transmission device, reduces the probability of failure due to structural complexity, helps extend the service life of the transmission device, reduces the frequency of maintenance and component replacement, and enhances overall performance and economy.

[0059] Furthermore, both the first transmission plate 61 and the second transmission plate are provided with transmission grooves 65, and the side of the rotating member 5 with the shaft hole 51 is located between the first back plate 41 and the second back plate 42.

[0060] Both the first transmission plate 61 and the second transmission plate are provided with transmission grooves 65, so that the rotating shaft 7 has corresponding moving tracks on both sides. This double-sided symmetrical structure provides more uniform and stable support and guidance for the rotating shaft 7. When the rotating shaft 7 moves during transmission, the transmission grooves 65 on both sides work together to effectively prevent the rotating shaft 7 from deviating or wobbling due to unilateral force or insufficient support. This ensures that the rotating shaft 7 always moves smoothly along the predetermined trajectory within the transmission grooves 65, thereby ensuring the accuracy and stability of motion conversion between the rotating component 5 and the transmission component 6, which meets the requirements of precise and stable operation of key moving parts in mechanical transmission. In addition, by placing the side of the rotating component 5 with the shaft hole 51 between the two back plates and making the rotating shaft 7 cooperate with the transmission grooves 65 on the two back plates, a compact and orderly transmission structure is constructed within the limited internal space of the box 4. This layout makes full use of the space between the back plates, making the relative positions of the components clearer and more reasonable. It facilitates coordination with other peripheral components (such as transmission bar 1, buffer pad, etc.), enhances the integrity and coordination of the overall structure of the transmission device, optimizes space utilization efficiency, and avoids space waste and difficulties in assembly and maintenance caused by loose or unreasonable component layout. It is in line with the design concept of the entire transmission device for compact structure and easy operation.

[0061] See Figures 1 to 5 As shown, in one specific embodiment, the transmission device further includes a cover 8, and the transmission bar 1 is slidably connected to the cover 8.

[0062] Specifically, the cover 8 is located on the side of the transmission bar 1 away from the profile 31, and its primary function is to provide protection. During daily use of doors and windows and under various environmental conditions, the cover 8 can prevent dust, moisture, foreign objects, and other external factors from entering the area where the transmission bar 1 is located. This prevents these impurities from adhering to the surface of the transmission bar 1, affecting the smoothness of its sliding connection with other components (such as connecting rods) and the overall transmission performance. It protects the transmission bar 1 and the entire transmission path, helping to maintain the normal operation of the transmission device and extend its service life. The transmission bar 1 is slidably connected to the cover 8, meaning that the cover 8 provides an additional support surface for the transmission bar 1. When the transmission bar 1 slides, the cover 8 can apply a certain constraint to the transmission bar 1, making its movement trajectory more stable and reducing potential instability such as swaying or deviation during movement. This ensures that the transmission bar 1 can slide accurately along the predetermined direction, guaranteeing the precision of the cooperation between the transmission bar 1 and other components during power transmission, meeting the requirement for stable movement of key moving components in mechanical transmission.

[0063] In one specific embodiment, the transmission device further includes a first connecting component 9, one end of which is connected to the cover 8 and the other end of which is used to connect to the box 4.

[0064] More specifically, the first connecting assembly 9 includes a first screw 91 and a nut block 92, the nut block 92 being installed between the first back plate 41 and the second back plate 42, one end of the first screw 91 being connected to the cover 8, and the other end being connected to the nut block 92.

[0065] The first connecting assembly 9 uses a combination of a first screw 91 and a nut block 92. By installing the nut block 92 between the first back plate 41 and the second back plate 42, a solid connection base is provided for the first screw 91. One end of the first screw 91 is connected to the cover 8, and the other end is screwed into the nut block 92, forming a simple and reliable connection. This connection utilizes the tightening principle of screws and nuts, and can maintain the relative position stability between the cover 8 and the box 4 under certain tensile and shear forces, thus ensuring the structural stability of the entire transmission device.

[0066] Furthermore, the first back plate 41, the second back plate 42, the first buffer pad 43, the second buffer pad 44 and the nut block 92 are all provided with fixing holes 45, and the first back plate 41, the second back plate 42, the first buffer pad 43, the second buffer pad 44 and the nut block 92 are detachably fixedly connected by fixing posts 46 connected to the fixing holes 45.

[0067] Specifically, the fixing post 46 connects multiple components into a whole, ensuring the stability of their relative positions. This allows components such as the first back plate 41, the second back plate 42, the first buffer pad 43, the second buffer pad 44, and the nut block 92 to work collaboratively under load, improving structural stability. During long-term use, this connection method effectively prevents transmission performance degradation or structural damage caused by loose connections between components, ensuring the reliability of the transmission device. Even under complex operating environments and frequent operation, it maintains good working condition. Furthermore, the simple fixing post 46 connection method optimizes the internal spatial layout of the transmission device, avoiding the use of complex connecting components, making the entire structure more compact and improving space utilization. Simultaneously, during assembly, the fixing holes 45 provide clear positioning for the components, making assembly operations simpler, reducing assembly difficulty and time, improving assembly efficiency, facilitating mass production and large-scale application, and also facilitating component disassembly and maintenance.

[0068] In one specific embodiment, the transmission device further includes a second connecting component 10, one end of which is connected to the cover 8, and the other end is used to connect to the profile 31.

[0069] Specifically, the second connecting component 10 is a second screw 101, with its two ends connected to the cover 8 and the profile 31, respectively. The second connecting component 10 uses the second screw 101 to directly connect the cover 8 and the profile 31, using the screw's tightening force to tightly connect the two components. Screws, as a common connecting element, have advantages such as simple structure, strong connection, and low cost. They can effectively connect different components tightly together, ensuring that the relative position between the cover 8 and the profile 31 remains unchanged during the operation of the transmission device, while also transmitting the corresponding force to ensure the integrity of the entire structure. Through the first connecting component 9 and the second connecting component 10, the cover 8 forms a detachable fixed connection with the box 4 and the profile 31. This design connects the cover 8, box 4, and profile 31 into a whole, ensuring smooth force transmission between components during the operation of the transmission device, maintaining the stability of the entire structure, and avoiding disruption of the overall force balance and structural stability due to loose connections. This ensures reliable operation of the transmission device and achieves a functional organic combination of convenient disassembly and structural stability. Furthermore, during operation, since the cover 8, box 4, and profile 31 are in a fixed state, the transmission structure between the rotating part 5, transmission part 6, transmission bar 1, and connecting rod is more stable, thereby improving the reliability of the transmission device.

[0070] See Figures 5 to 7 As shown, in a specific embodiment, the transmission bar 1 is further provided with a sliding groove 12. The length direction of the sliding groove 12 is consistent with the transmission direction of the transmission bar 1. The first connecting component 9 and the second connecting component 10 both pass through the sliding groove 12.

[0071] Specifically, the length of the sliding groove 12 is longer than the distance between the first connecting component 9 and the second connecting component 10. The longer sliding groove 12 provides ample space for the movement of the transmission bar 1, avoiding obstruction of its normal movement due to the length limitation of the connecting components. This ensures that the transmission bar 1 can move freely in its transmission direction, making power transmission smoother and improving the working efficiency of the transmission device. Simultaneously, the through-type connecting component ensures stable force transmission, guaranteeing a stable and reliable force transmission path from other components to the transmission bar 1, and improving the accuracy and stability of the locking point control.

[0072] In one specific embodiment, there are two sliding grooves 12, and the two sliding grooves 12 are located at both ends of the transmission member 6, and the first connecting component 9 and the second connecting component 10 are both provided corresponding to the sliding grooves 12.

[0073] Specifically, the two sliding grooves 12 provide more precise motion guidance for the transmission bar 1, improving the motion accuracy and stability of the connecting components and avoiding potential motion deviations that may occur with the single-track sliding groove 12. This enhances the precision of the locking point control, making the opening and closing of doors and windows more accurate. The precise motion trajectory ensures efficient power transmission within the transmission device, avoiding energy loss and reduced power transmission efficiency due to motion deviations. This allows the entire transmission device to more accurately transmit power from the transmission bar 1 to the locking point, improving the performance and user experience of the transmission device. The number of the first connecting component 9 and the second connecting component 10 corresponds to the number of sliding grooves 12, and both are set in two sets. This makes the connection structure between the cover 8, the box 4, and the profile 31 more balanced and stable, significantly enhancing the structural stability of the transmission device. By balancing forces and providing precise motion guidance, damage to components caused by uneven forces and unstable motion is reduced. This allows the transmission device to remain stable when subjected to various external impacts from door and window opening and closing, as well as forces generated by internal transmission, extending the service life of the transmission device and ensuring reliable locking point control during long-term use.

[0074] See Figures 2 to 5 As shown, in a specific embodiment, the cover 8 is provided with two first support portions 81 along the length direction of the cover 8 on the side close to the transmission bar 1, the transmission bar 1 is located between the two first support portions 81, and the side of the transmission bar 1 close to the cover 8 is provided with two second support portions 13 corresponding to the two first support portions 81, the second support portions 13 are attached to the first support portions 81.

[0075] Specifically, the fitting design of the first support part 81 and the second support part 13 significantly enhances the structural stability of the transmission bar 1, providing stable support and positioning for the transmission bar 1. This allows the transmission bar 1 to withstand greater forces during movement without shifting, reducing the risk of transmission failures caused by instability of the transmission bar 1 and ensuring the stable operation of the entire transmission device. Even under the impact of frequent opening and closing of doors and windows or other external forces during long-term use, this support structure can ensure the stability of the transmission bar 1's position, extending the service life of the transmission device and improving the overall reliability of the transmission device.

[0076] See Figure 6 As shown, in one specific embodiment, both ends of the transmission bar 1 are connected to support blocks 14, and the two sides of the support blocks 14 respectively abut against two second support parts 13.

[0077] Specifically, the stamping column 2 has a through hole (not shown in the figure), and the support block 14 is connected to the through hole. By setting the support block 14, the transmission bar 1 can be additionally supported and reinforced, preventing deformation or displacement of the transmission bar 1 during movement or under force, thus improving the structural stability of the transmission bar 1. The support block 14 is connected to the through hole in the stamping column 2, ensuring the reliability of the connection between the support block 14 and the transmission bar 1. This allows the support block 14 to stably provide support and reinforcement for the transmission bar 1, preventing loss of support due to loose connection during use, ensuring the stability and reliability of the entire structure. Furthermore, the stamping column 2 is reused, avoiding the need for additional connecting structures, making the entire transmission device structure more compact. Since the stamping column 2 is made using a stamping process, the connection structure between the stamping column 2 and the connecting hole is not easily damaged, further improving the reliability of the connection.

[0078] In one specific embodiment, the transmission bar 1 is a stainless steel transmission bar 1.

[0079] Specifically, the high strength and corrosion resistance of the stainless steel transmission bar 1 ensure that the power transmitted from the transmission component 6 is transmitted to the stamping column 2 more stably and reliably, reducing the risk of power loss or transmission interruption due to the degradation of the transmission bar 1's own performance, thereby ensuring smooth and reliable operation of doors and windows. In conjunction with the one-piece molded stamping column 2 structure, the excellent mechanical properties of stainless steel help ensure the strong and integral connection between the two, preventing loosening or damage at the connection due to excessive differences in the thermal expansion coefficients of different materials. Furthermore, the rigidity of stainless steel allows for better coordination with the transmission components 3 (such as profile 31, transmission rod 32, etc.), improving the overall coordination performance of the transmission system and preventing issues with the transmission bar 1 from affecting the fit between the door and window locking points and lock seats, thus ensuring the safety performance of the doors and windows.

[0080] See Figures 1 to 11 As shown, this utility model also provides a door and window, which includes the transmission device as described above.

[0081] Specifically, the doors and windows also include the door frame, profile 31, transmission rod 32, locking point, and lock seat as described above. The transmission device, profile 31, transmission rod 32, locking point, and lock seat are all installed on the door frame. This door and window design organically integrates the aforementioned transmission device with the door frame, profile 31, transmission rod 32, locking point, and lock seat. When it is necessary to open or close the doors and windows, an external force is applied to the transmission bar 1 of the transmission device. Since the stamping column 2 is integrally formed with the transmission bar 1, the stamping column 2 will move with the transmission bar 1; the stamping column 2 drives the transmission rod 32 connected to it to slide within the profile 31; the sliding of the transmission rod 32 will drive the locking point of the door and window to move, and the movement of the locking point will change its engagement state with the lock seat, thereby controlling the opening and closing of the doors and windows.

[0082] The integrated molding structure of the stamped column 2 and the transmission bar 1 in the transmission device ensures the stability of power transmission, avoiding the brittle fracture problem that may occur due to traditional connection methods, and improving the safety and reliability of the transmission. The gradual deformation characteristics of the stamped column 2 can prevent sudden failure under overload, further ensuring the safety of doors and windows during use, especially for some large or heavy doors and windows, which can better cope with possible sudden loads. The entire door and window system tightly integrates the transmission device and other components of the door and window, reducing the complex connection structure between components, simplifying the assembly process, improving assembly efficiency, and making the overall structure more compact, reducing possible failure points. This integrated design can improve the overall performance of doors and windows and reduce various problems caused by loose connections or poor fit of components, such as loosening and jamming. Reliable power transmission from the transmission bar 1 to the transmission component 3 allows for more precise control of the opening and closing of doors and windows, and users can more easily adjust the opening and closing degree of doors and windows, improving the user experience.

[0083] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
