Technical Field
[0001] This utility model relates to the technical field of door and window hardware, and in particular to a door and window hardware with a surface corrosion resistant coating. Background Technology
[0002] In the field of architectural decoration, traditional door and window hardware is mostly made of metal, relying on its high strength and good mechanical properties to enable the opening and closing of doors and windows. However, during the decoration process, metal surfaces are easily contaminated by acidic and alkaline substances such as cement, leading to rust.

However, electroplating layers are prone to wear and peeling, and anti-rust paint has poor weather resistance and is prone to aging and cracking with long-term use. Rusting of metal not only reduces the strength of hardware but also affects the appearance of doors and windows. Utility Model Content

[0061] Furthermore, in a preferred embodiment, the first transmission bar 112 and the second transmission bar 113 are symmetrically arranged; the first transmission bar 112 is provided with a first coupling portion 1121, and the second transmission bar 113 is provided with a second coupling portion 1131; one end of any connecting rod 21 is provided with a rack portion 212, and the other end of the connecting rod 21 is provided with a rack portion 212 or a third coupling portion 213; both ends of any corner actuator 31 are provided with a fourth coupling portion 34; furthermore, the first slide rail 311 and the second slide rail 312 on this corner actuator 31 are each provided with...

When installing the connecting rod assembly 2, firstly, place the first snap-fit part 222 on the second nylon shell 22 into one side of the C-shaped groove, and at the same time, mate the rack parts 212 at both ends of the connecting rod 21 with their corresponding two coupling parts. Then, the connecting rod assembly 2 is pushed towards the C-shaped groove. Due to the reaction force of the C-shaped groove, the second nylon shell 22 undergoes elastic deformation. When the second snap-fit part 223 snaps into the other side of the C-shaped groove, the second nylon shell 22 elastically returns to its original position, thus completing the installation. After installation, the C-shaped groove limits the second nylon shell 22 to maintain its stability.
[0062] Furthermore, in a preferred embodiment, each rack portion 212 has sequentially arranged toothed structures on both sides; the first coupling portion 1121 has two rows of toothed structures, which respectively engage with and limit the toothed structures on both sides of the rack portion 212; the second coupling portion 1131 has two rows of toothed structures, which respectively engage with and limit the toothed structures on both sides of the rack portion 212; the third coupling portion 213 has two rows of toothed structures, which respectively engage with and limit the toothed structures on both sides of the rack portion 212 on different connecting rods 21; and the fourth coupling portion 34 has two rows of toothed structures, which respectively engage with and limit the toothed structures on both sides of the rack portion 212.
[0063] Furthermore, in a preferred embodiment, the linkage assembly 2 further includes two limiting strips 23. The two ends of each limiting strip 23 are connected to the two sides of the second nylon shell 22, and both limiting strips 23 are used to limit the linkage 22.
[0064] Furthermore, in a preferred embodiment, the connecting rod 21 is provided with a through hole 211, and the second nylon shell 22 is provided with a shear pin 224. The shear pin 224 is placed inside the through hole 211. When the lock body 11 moves the connecting rod 21 for the first time, it destroys the shear pin 224. The function of the shear pin 224 is to limit the connecting rod 21 before installation, preventing the connecting rod 21 and the second nylon shell 22 from moving relative to each other in the length direction, thus facilitating storage and installation.
[0065] Furthermore, in a preferred embodiment, the first nylon shell 12, the second nylon shell 22, the third nylon shell 32, and the fourth nylon shell 33 are all made of nylon material, which, due to its good toughness and certain elasticity, facilitates installation.
[0066] Installation steps:
[0067] First, install the lock body assembly 1 on the side of the door or window that can be opened.
[0068] Then, install a corner actuator assembly 3 at each of the two corners on the open side. Specifically: first, place the third locking part 3111 and the fifth locking part 3122 of one corner actuator assembly 3 into one side of the C-shaped slot, and then push the fourth locking part 324 and the sixth locking part 334 into the other side of the C-shaped slot. The other corner actuator assembly 3 is installed in the same way.
[0069] Next, install the connecting rod assembly 2, connecting the lock body assembly 1 to the two corner transmission assemblies 3. Specifically: first, place the first snap-fit portion 222 on the second nylon housing 22 into one side of the C-shaped groove; simultaneously, align the rack portions 212 at both ends of the connecting rod 21 with their corresponding two coupling components. Then, push the connecting rod assembly 2 towards the C-shaped groove. Due to the reaction force of the C-shaped groove, the second nylon housing 22 undergoes elastic deformation. When the second snap-fit portion 223 snaps into the other side of the C-shaped groove, the second nylon housing 22 elastically returns to its original position, thus completing the installation. After installation, the C-shaped groove limits the second nylon housing 22 to maintain its stability.
[0070] In summary, when the lock body assembly 1, the connecting rod assembly 2, and the corner transmission assembly 3 are installed in the mounting groove on the side of the door or window sash, the first nylon shell 12, the second nylon shell 22, the third nylon shell 32, and the fourth nylon shell 33, with their wear-resistant and corrosion-resistant nylon material and structural design, isolate the inner metal parts from the external environment, effectively preventing the metal parts from rusting and providing protection.
[0071] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
