XINMEIDE AUXILIARY LOCKS
Core Products
Auxiliary locks are auxiliary anti-theft reinforcement components besides the main door lock. Specifically designed to improve the anti-theft level of entrance doors, security doors and villa gates, they effectively enhance the door's resistance to violent opening and prevent risks such as prying and breaking through multi-directional locking structures. Xinmeide auxiliary locks are widely compatible with various doors such as steel security doors, solid wood entrance doors, villa copper doors and engineering gates, forming a double protection system with the main lock. Covering scenarios like home decoration, high-end villas and commercial buildings, they provide door manufacturers with highly reliable anti-theft reinforcement solutions.
Product Series
Specializing in the R&D and production of auxiliary locks, Xinmeide offers a full range of high-quality products. The detailed categories and core advantages are as follows:
1. Classified by Installation Position
Heaven-Earth Auxiliary Locks: Adopt upper and lower synchronous bolt design, precisely engaging with the locks at the top and bottom of the door to form vertical locking reinforcement, preventing the door from being forced pried and deformed. Suitable for doors with high anti-theft requirements such as security doors and villa gates, the bolts stretch smoothly, enabling more convenient linkage control with the main lock.
Side Auxiliary Locks: Installed on the side of the door, forming horizontal multi-layer protection with the main lock points. The bolts are thickened and reinforced, featuring excellent impact resistance and saw-proof performance. Suitable for high-frequency use scenarios such as entrance doors and shop doors, effectively improving the overall anti-theft stability of the door.
Concealed Auxiliary Locks: Embedded structural design, flush with the door surface after installation, without damaging the door's appearance. Meanwhile, it avoids the bolt being exposed and damaged by external forces, suitable for scenarios that value both appearance and performance such as high-end villa doors and customized entrance doors.
2. Classified by Material
304 Stainless Steel Auxiliary Locks: Made of high-quality stainless steel plates by stamping, with precision polishing and anti-rust treatment. Moisture-resistant and corrosion-resistant, suitable for outdoor gates and doors in coastal areas, not easy to rust or deform after long-term use, with a long service life.
Zinc Alloy Auxiliary Locks: Hard texture and high malleability, supporting surface processes such as electroplating and spraying, with rich colors and high cost-effectiveness. Suitable for scenarios such as indoor entrance doors and ordinary security doors, balancing anti-theft performance and cost control.
3. Classified by Control Method
Linkage-type Auxiliary Locks: Linked with the main lock handle, rotating the main lock handle can synchronously control the opening and closing of the auxiliary lock. Easy to operate without separate control, suitable for scenarios pursuing convenience such as home entrance doors and apartment doors.
Independent-type Auxiliary Locks: Equipped with exclusive control knobs or keys, which can be opened or locked independently, flexibly adapting to different needs. For example, lock the auxiliary lock to enhance anti-theft when no one is at home, and only use the main lock for convenient entry and exit when someone is at home.
