Technical Field
[0001] This utility model relates to the field of handle technology, specifically a safety handle connection structure. Background Technology
[0002] Safety handles are operating parts for doors, windows, or equipment specifically designed to prevent children from accidentally opening them. They enhance safety through multiple protective structures and employ a combination operation (such as pressing and rotating) or an additional locking device to make operation more difficult than a child's ability, thus preventing accidental opening. They are also made of drop-resistant and flame-retardant materials, with rounded surfaces to prevent bumps and knocks. Suitable for home doors, windows, cabinets, and other scenarios, they effectively prevent children from accidentally opening them out of curiosity, which could lead to dangers such as falls or contact with dangerous objects. They provide protection for children while also being easy for adults to use, balancing safety and convenience.
[0003] While existing detachable handle connection structures have improved the inconvenience of maintenance of traditional fixed handles, they still have significant drawbacks: disassembly requires special tools or repeated screw removal and installation, which is cumbersome and time-consuming. For example, in the maintenance of door and window handles in homes, users need to prepare additional tools such as screwdrivers and tighten the screws multiple times to complete the disassembly. For curtain wall handles installed at heights or equipment handles in narrow spaces, such operations are not only inefficient, but may also greatly increase the difficulty of maintenance due to the inconvenience of carrying tools or the limited operating space.

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.
[0024] Please see Figures 1-7In this embodiment of the present invention, a safety handle connection structure includes a mounting plate 1. A connecting ring 2 is fixedly connected to the middle of one side of the mounting plate 1. A connecting ring 3 is fixedly connected to the side of the connecting ring 2 away from the mounting plate 1. Circular connecting blocks 4 are passed through and fixedly connected to the upper and lower parts of the mounting plate 1. A rotating rod 5 is passed through and rotatably connected to the middle of the two circular connecting blocks 4. A locking plate 6 is fixedly connected to the side of the rotating rod 5 away from the circular connecting blocks 4. The other end of the rotating rod 5 passes through the circular connecting blocks 4 and is fixedly connected to a rotating plate 6. Mounting plate 2 8 is installed on the side of mounting plate 1 near the card plate 6. Mounting plate 2 8 is fixed to the preset position of the corresponding handle of the door and window sash with pre-installed screws, ensuring that the positioning hole is completely aligned with the reserved hole of the door and window profile. Then, the pre-assembled integrated module of mounting plate 1, connecting ring 1, connecting ring 2, and rotating handle 12 is attached to the outside of mounting plate 2 8, so that the square tenon at the end of the handle connecting rod 11 passes through the center hole of mounting plate 2 8 and connects with the internal transmission square shaft of the door and window. Mounting plate 2 8 has openings on both the upper and lower sides. The card plate corresponds to the slot 9, and the card plate 6 cooperates with the card plate corresponding to the slot 9. The card plates 6 on the upper and lower sides of the mounting plate 1 will be inserted into the card plate corresponding slot 9 of the mounting plate 2. Both sides of the inner cavity of the two card plate corresponding slots 9 are provided with arc-shaped grooves 10, and the arc-shaped grooves 10 communicate with the card plate corresponding slots 9. The side of the card plate 6 corresponding to the card plate corresponding slot 9 rotates in the arc-shaped groove 10. The mounting plate 1, the connecting ring 1, the connecting ring 2, and the middle of the mounting plate 2 are rotatably connected to the middle of the mounting plate 2. The handle connecting rod 11 is rotatably connected to the middle of the outer wall of the handle connecting rod 11. The limiting boss and the annular groove of the mounting plate 1 are precisely matched to ensure that the handle assembly maintains axial positioning accuracy during rotation. The handle connecting rod 11 is fixedly connected to the rotating handle 12 on the side away from the connecting ring 3. Rotating the handle 7 clockwise drives the eccentric rotating rod 5, causing the rotating plate 6 to rotate and lock in the arc groove 10. Finally, the reset baffle 22 automatically adsorbs and closes by using the magnetic block 23 and the magnetic block 21 to shield the operating parts and prevent accidental contact. When disassembling, it is only necessary to repeat the above steps in reverse, and no tools are needed throughout the process.
[0025] A slot 13 is formed on one side of the outer wall of the handle connecting rod 11, located within the inner cavity of the connecting ring 2 3. A sliding groove 14 is formed on the upper part of the inner cavity of the connecting ring 2 3. A pressing plate 15 is connected to the inner cavity of the sliding groove 14, and the bottom side of the pressing plate 15 is beveled. The top of the pressing plate 15 passes through the connecting ring 2 3 and is fixedly connected to a push plate 16. A compression groove 17 is formed at the bottom of the sliding groove 14 within the inner cavity of the connecting ring 2 3. A limiting plate 18 is slidably connected to one side of the inner cavity of the compression groove 17. Springs 19 are fixedly connected to both sides of the inner cavity of the compression groove 17 away from the limiting plate 18, and the tops of the springs 19 are fixedly connected to the limiting plate 18. A locking rod 20 is fixedly connected to the middle of the limiting plate 18, passing through the sliding groove 14. The top of the locking rod 20 abuts against the pressing plate 15, and the side of the locking rod 20 away from the limiting plate 18 passes through... The connecting ring 2 3 cooperates with the slot 13. When the door and window are not in use, the push plate 16 is pushed outward, which causes the pressing plate 15 to move laterally in the sliding groove 14. The beveled surface of the pressing plate 15 pushes the locking rod 20 and the spring 19 downward until the bottom of the locking rod 20 is fully inserted into the slot 13 opened at the top of the rotating handle 12, realizing the mechanical locking function and effectively preventing children from accidentally opening it. Magnetic blocks 21 are installed on both sides of the mounting plate 1 near the handle 7. The outer wall of the connecting ring 2 is rotatably connected to the baffle 22 between the mounting plate 1 and the connecting ring 2 3. Magnetic blocks 23 are fixedly connected to the side of the baffle 22 near the magnetic blocks 21, and the magnetic blocks 23 cooperate with the magnetic blocks 21. When the baffle 22 is moved, the magnetic blocks 23 are released from the magnetic lock and disengaged from the magnetic blocks 21, exposing the hidden handle 7.
[0026] The working principle of this utility model is as follows: When installing the door and window handle assembly, firstly, the mounting plate 28 is fixed to the preset position of the corresponding handle on the door and window sash using pre-installed screws, ensuring that the positioning hole is completely aligned with the reserved hole of the door and window profile. Then, the pre-assembled integrated mounting plate 1, connecting ring 12, connecting ring 23, and rotating handle 12 are attached to the outside of the mounting plate 28, so that the square tenon at the end of the handle connecting rod 11 passes through the center hole of the mounting plate 28 and connects with the internal transmission square shaft of the door and window. At this time, the clamping plates 6 on the upper and lower sides of the mounting plate 11 will... Insert the card into the corresponding slot 9 of the mounting plate 28 to form the initial positioning. Then, rotate the baffle 22 to release the magnetic lock. Magnetic block 23 disengages from magnetic block 121, exposing the hidden handle 7. Rotate the handle 7 clockwise to drive the eccentric rotating rod 5, causing the rotating card 6 to rotate and lock in the arc groove 10. Finally, the baffle 22 is reset to automatically adsorb and close using magnetic block 23 and magnetic block 121, shielding the operating parts to prevent accidental contact. When disassembling, simply repeat the above steps in reverse. No tools are needed throughout the process, allowing for quick installation and disassembly.
[0027] When the doors and windows are not in use, push the push plate 16 outward to cause the pressing plate 15 to move laterally in the sliding groove 14. The angled surface of the pressing plate 15 pushes the locking rod 20 and the spring 19 downward until the bottom of the locking rod 20 is fully inserted into the locking groove 13 opened at the top of the rotating handle 12, thereby realizing the mechanical locking function and effectively preventing children from accidentally opening it.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
