Description

Technical Field

[0001] This utility model relates to a transmission connection component for windows, belonging to the field of door and window components. Background Technology

[0002] Existing plastic windows use several drive components to open and close the window sash. The transmission locking mechanism typically consists of a fixed rod and a sliding rod, with the sliding rod slidably connected to the fixed rod by rivets. The sliding rod usually has a serrated shape, which engages with another serrated shape on the drive component at the corner of the plastic window to achieve the connection and drive of the components. This connection method causes a significant reduction in transmission efficiency due to dimensional deviations when power is transmitted to the next drive component, resulting in errors in the transmission stroke. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a transmission connection component for windows.

[0004] A window transmission connection assembly is installed within a U-shaped window sash. The assembly includes a fixed rod, a handle, a drive component, a corner component, and an adjusting block connecting the fixed rod and the corner component. The corner component has a sliding rod with a rack at its end. One end of the adjusting block is connected to the fixed rod, and the other end is linked to the rack. The adjusting block has an adjusting element. The overall length of the fixed rod and the corner component is adjusted by the adjusting element driving relative sliding between the adjusting block and the rack. The design of the adjusting block and adjusting element effectively adjusts the relative position between the fixed rod and the corner component, thereby reducing the decrease in transmission efficiency caused by dimensional deviations. The adjustment process can be precisely controlled, ensuring the meshing accuracy between the sliding rod and the rack, and improving the stability and efficiency of power transmission. Using an adjusting block to connect the fixed rod and the corner component simplifies the interconnection between multiple drive components in traditional structures.

[0005] Preferably, the adjusting block includes an adjusting part and a connecting part. The adjusting part has an adjusting hole, and the adjusting element passes through the adjusting hole and abuts against the rack, forming a tight fit between the adjusting part and the rack. This tight fit between the adjusting part and the rack not only reduces transmission errors but also improves the stability of the overall structure. During long-term use, this design helps avoid structural deformation caused by loosening or uneven friction, thereby improving the durability and reliability of the entire transmission system.

[0006] Furthermore, the rack is provided with a first fixing hole, through which the adjusting member passes and connects to the sliding rod. The adjusting member can be tightly connected to the first fixing hole through the adjusting hole. This connection method ensures reliable fixation between the adjusting part and the rack, avoiding errors or loosening caused by weak connection.

[0007] Furthermore, the adjusting component is a bolt, the bottom surface of the adjusting part mates with the toothed surface of the rack, the adjusting hole is an elongated slot, and the bolt passes through the adjusting hole and is fixedly connected to the first fixing hole to determine the position of the adjusting block and the corner component. When the bolt is disconnected from the first fixing hole, the overall length of the fixing rod and the corner component can be adjusted. When it is necessary to adjust the overall length of the fixing rod and the corner component, after the connection between the bolt and the first fixing hole is released, the user can adjust the relative position of the two by moving the bolt within the adjusting hole. This simplifies the adjustment process, eliminating the need for complex disassembly steps, and allowing for quick and convenient fine adjustment of the overall length of the fixing rod and the corner component.

[0008] Furthermore, the bottom of the adjusting part is smooth, and the adjusting component is an eccentric rivet. The eccentric rivet adjusts the overall length of the fixing rod and the corner component through rotation within the first fixing hole. The eccentric rivet design allows for fine-tuning of the contact force between the bottom surface of the adjusting part and the rack through eccentric rotation. Since the rotation of the eccentric rivet causes the adjusting part to shift along the rack direction during adjustment, the overall length of the fixing rod and the corner component can be precisely adjusted. The smooth bottom surface of the adjusting part ensures less friction when in contact with the rack, reducing wear and improving transmission efficiency.

[0009] Furthermore, the connecting part is provided with a first cylindrical pin, and the end of the fixing rod is provided with a second fixing hole. The adjusting hole is fixedly connected to the second fixing hole through the first cylindrical pin. Fixing the adjusting hole and the second fixing hole together with the first cylindrical pin effectively avoids transmission errors caused by loose or misaligned connections. This simplifies the adjustment and connection structure, eliminating the need for complex threads or multiple adjustment components. This structure is simpler and more direct, reducing the complexity of assembly and adjustment, and improving the reliability and durability of the system.

[0010] Preferably, the handle is fixedly mounted on the drive component via a square shaft, the bottom of the fixing rod is provided with a third fixing hole, and the drive component is provided with a second cylindrical pin fixedly connected to the third fixing hole. The connection between the third fixing hole and the second cylindrical pin can prevent misalignment or displacement between components, thereby ensuring that the fixing rod and the drive component maintain a stable relative position during operation, enhancing the reliability and transmission accuracy of the system.

[0011] Preferably, the fixed rod has sliding grooves on both sides, and the U-shaped profile has sliding blocks that slidably engage with the sliding grooves. The sliding blocks can precisely guide the fixed rod to slide along a set trajectory, ensuring relative position stability during transmission and avoiding transmission errors caused by inaccurate engagement. The engagement of the sliding grooves and sliding blocks makes the movement of the fixed rod within the U-shaped profile smoother, reducing the swaying or uneven movement problems that may occur in traditional designs.

[0012] The beneficial effects of this invention are as follows: The design of the adjusting block and adjusting component effectively adjusts the relative position between the fixed rod and the corner component, thereby reducing the decrease in transmission efficiency caused by dimensional deviations. The adjustment process can be precisely controlled, ensuring the meshing accuracy between the sliding rod and the rack, and improving the stability and efficiency of power transmission. Using the adjusting block to connect the fixed rod and the corner component simplifies the interconnection between multiple drive components in traditional structures. Attached Figure Description

[0023] like Figure 1-5 As shown, this is an embodiment of a window transmission connection assembly of the present invention. Installed within a U-shaped window sash 1, the transmission connection assembly includes a fixed rod 2, a handle 3, a driving component 4, a corner component 5, and an adjusting block 6 for connecting the fixed rod 2 and the corner component 5. The corner component 5 is provided with a sliding rod 51, and the end of the sliding rod 51 is provided with a rack 511. One end of the adjusting block 6 is connected to the fixed rod 2, and the other end is linked to the rack 511. The adjusting block 6 is provided with an adjusting element 7. The overall length of the fixed rod 2 and the corner component 5 is adjusted by the adjusting element 7 driving the adjusting block 6 to slide relative to the rack 511. Through the design of the adjusting block 6 and the adjusting element 7, the relative position between the fixed rod 2 and the corner component 5 can be effectively adjusted, thereby reducing the decrease in transmission efficiency caused by dimensional deviations. The adjustment process can be precisely controlled to ensure the meshing accuracy between the sliding rod 51 and the rack 511, improving the stability and efficiency of power transmission. The use of adjusting block 6 to connect fixed rod 2 and corner component 5 simplifies the interconnection between multiple drive components 4 in the traditional structure.

[0024] The adjusting block 6 includes an adjusting part 61 and a connecting part 62. The adjusting part 61 is provided with an adjusting hole 611. The adjusting member 7 passes through the adjusting hole 611 and abuts against the rack 511, forming a tight fit between the adjusting part 61 and the rack 511. The tight fit between the adjusting part 61 and the rack 511 not only reduces transmission errors but also improves the stability of the overall structure. During long-term use, this design helps to avoid structural deformation caused by loosening or uneven friction, thereby improving the durability and reliability of the entire transmission system.

[0025] The rack 511 is provided with a first fixing hole 512. The adjusting member 7 passes through the adjusting hole 611 and the first fixing hole 512 and is connected to the sliding rod 51. The adjusting member 7 can be tightly connected to the first fixing hole 512 through the adjusting hole 611. This connection method ensures reliable fixation between the adjusting part 61 and the rack 511 and avoids errors or loosening caused by weak connection.

[0026] The adjusting component 7 is a bolt 71. The bottom surface of the adjusting part 61 mates with the toothed surface 612 of the rack 511. The adjusting hole 611 is an elongated slot. The bolt 71 passes through the adjusting hole 611 and is fixedly connected to the first fixing hole 512 to determine the position of the adjusting block 6 and the corner component 5. When the bolt 71 is disconnected from the first fixing hole 512, the overall length of the fixing rod 2 and the corner component 5 can be adjusted. When it is necessary to adjust the overall length of the fixing rod 2 and the corner component 5, after the connection between the bolt 71 and the first fixing hole 512 is released, the user can adjust the relative position of the two by moving the bolt 71 within the adjusting hole 611. This simplifies the adjustment process, eliminating the need for complex disassembly steps, and allowing for quick and convenient fine adjustment of the overall length of the fixing rod 2 and the corner component 5.

[0027] This embodiment differs from the previous embodiment in that the bottom of the adjusting part 61 is smooth, and the adjusting member 7 is an eccentric rivet 72. The eccentric rivet 72 adjusts the overall length of the fixing rod 2 and the corner component 5 through rotation within the first fixing hole 512. Due to the design of the eccentric rivet 72, the contact force between the bottom surface of the adjusting part 61 and the rack 511 can be finely adjusted through eccentric rotation. Since the rotation of the eccentric rivet 72 causes the adjusting part 61 to shift along the rack 511 during adjustment, the overall length of the fixing rod 2 and the corner component 5 can be precisely adjusted. The smooth bottom surface of the adjusting part 61 ensures less friction when it contacts the rack 511, reducing wear and improving transmission efficiency.

[0028] The connecting part 62 is provided with a first cylindrical pin 621, and the end of the fixing rod 2 is provided with a second fixing hole 21. The adjusting hole 611 is fixedly connected to the second fixing hole 21 through the first cylindrical pin 621. Fixing the adjusting hole 611 and the second fixing hole 21 through the first cylindrical pin 621 effectively avoids transmission errors caused by loose connections or misalignments. This simplifies the adjustment and connection structure, eliminating the need for complex threads or multiple adjustment components. This structure is simpler and more direct, reducing the complexity of assembly and adjustment, and improving the reliability and durability of the system.

[0029] The handle 3 is fixedly mounted on the drive component 4 via a square shaft 31. The bottom of the fixing rod 2 is provided with a third fixing hole 22, and the drive component 4 is provided with a second cylindrical pin 41 fixedly connected to the third fixing hole 22. The connection between the third fixing hole 22 and the second cylindrical pin 41 can prevent the components from shifting or misaligning, thereby ensuring that the fixing rod 2 and the drive component 4 maintain a stable relative position during operation, enhancing the reliability and transmission accuracy of the system.

[0030] The fixed rod 2 has sliding grooves 23 on both sides, and the U-shaped profile 1 has sliding blocks 11 that slide in conjunction with the sliding grooves 23. The sliding blocks 11 can precisely guide the fixed rod 2 to slide along a set trajectory, ensuring the relative position stability during transmission and avoiding transmission errors caused by inaccurate fit. The cooperation between the sliding grooves 23 and the sliding blocks 11 makes the movement of the fixed rod 2 within the U-shaped profile 1 more stable, reducing the swaying or uneven movement problems that may occur in traditional designs.

[0031] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.

[0032] Although the present invention has been described with reference to several specific embodiments, it should be understood that the present invention is not limited to the specific embodiments disclosed. The present invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
