Product Advantages
|
Functional dimensions |
Unique advantages of PVC lock buckle |
Compared with traditional metal locks |
|
Dynamic stress compensation |
Elastic slot absorbs thermal expansion and contraction of the door body (±3mm) |
Hard connection of metal parts can easily cause cracks in PVC doors |
|
Anti-theft and anti-pry |
Hidden ratchet structure, the greater the external force, the tighter the lock |
Exposed lock tongue can be easily attacked by crowbars |
|
Silent closure |
Silicone damping layer reduces impact noise (<30 dB) |
The sound of metal collision can reach 60 decibels |
|
Visual invisibility |
The lock body is embedded in the grid, with only 2mm trigger paddle exposed |
External locks destroy the overall beauty of the fence |
Material advantages
1. Three-layer composite structure
[Outer layer] Anti-UV modified PVC
│── Anti-ultraviolet agent concentration 12%, 10-year fading rate <5%
[Middle layer] Glass fiber reinforced layer
│──Tensile strength increased to 65MPa (pure PVC only 40MPa)
[Inner layer] 304 stainless steel movement
│──Salt spray test > 1000 hours without rust
2. Low temperature toughness guarantee
-40℃ anti-brittle crack formula: Add elastomer POE (ethylene-octene copolymer), impact strength retention rate > 85%
Freeze-thaw test: -30℃→25℃ cycle 50 times, lock opening and closing resistance change ≤15%
Advantages and features
-
Super weather resistanceThrough professional weather resistance tests, the color change does not exceed 0.5 NBS units after continuous exposure to ultraviolet radiation of 80W/㎡ for 6000 hours; the lock buckle has no deformation, cracking, etc. after 100 cycles of testing in extreme temperature environments of -40℃ to 70℃. It can adapt to various harsh climate conditions and its service life far exceeds that of similar products.
-
Silent opening and closingThe lock core adopts a unique tooth design and precision manufacturing process, and the anti-pry level reaches Class C. After simulated violent opening tests, it can still maintain structural integrity when subjected to external forces exceeding 1500N, effectively preventing illegal intrusions and providing reliable security for homes, parks and other places.
-
Convenient installationEquipped with a full range of installation components, including screws, expansion tubes, etc. According to actual tests, ordinary users follow the installation guide and can complete the installation of a single lock buckle in an average of only 10 minutes, which is 60% higher than the installation efficiency of traditional fence lock buckles.
-
Low maintenance costDue to the combination of PVC materials and stainless steel parts, the lock does not need frequent maintenance work such as painting and rust prevention. Compared with iron locks, it can save about 80% of maintenance costs each year, greatly reducing the user's use burden.
-
Not easily deformedA special silent buffer gasket is added to the movable parts of the lock, and the noise generated when opening and closing the door is less than 25 decibels. It is especially suitable for noise-sensitive places such as residential areas, schools, hospitals, etc., to create a quiet and comfortable environment.
-
Wide adaptabilityThrough testing of more than 100 different specifications and types of PVC fence doors on the market, the lock can adapt to more than 95% of the products, whether it is a single door, double door, or fence doors of different thicknesses (10mm - 50mm) and widths, it can be easily installed and used to meet diverse market needs.

|
Weather resistance |
Place the lock in a simulated extreme climate environment chamber to simulate strong ultraviolet rays, heavy rain, high temperature, low temperature and other conditions, and continue testing for 18 months |
No obvious fading or deformation on the exterior, normal function |
Meet the standards, stable performance |
|
Anti-theft performance |
Use professional lock picking tools and equipment to simulate violent lock picking, technical lock picking and other behaviors |
Within the specified time (30 minutes), the lock core is not damaged and the lock buckle is not opened |
Excellent anti-theft performance |
|
Durability |
Use automated equipment to simulate the lock opening and closing 200 times a day, and test the equivalent number of times for 8 years |
Opening and closing are smooth, the wear of parts is within the allowable range, and there is no damage |
Long service life, meet long-term use needs |
|
Ease of installation |
Invite personnel with different professional levels to install, record the installation time and operation difficulty feedback |
The average installation time does not exceed 15 minutes, and the operation is simple and easy to understand |
Easy to install, good user experience |
|
Noise |
In a silent environment, use a high-precision noise tester to measure the noise generated when the lock is opened and closed |
The noise value does not exceed 30 decibels |
Achieve silent effect, excellent performance |
|
Adaptability |
Select PVC fence doors of different brands and specifications on the market for installation testing |
Can adapt to more than 95% of PVC fence doors |
Wide adaptation range, strong compatibility |
