The Toilet Cubicle Hinges are stainless steel spring hinges designed specifically for public toilet partition doors, ensuring automatic return and stable rotation. Typically installed on glass or compact panel doors, they automatically return to a closed or neutral position after opening, providing enhanced privacy and cleanliness. Their matte satin finish resists fingerprints and scale, providing a smooth touch. Designed to balance safety and practicality, they offer stability and durability even under frequent use in public spaces, providing a reliable opening and closing experience for toilet partition systems.

High-Precision Shaft

The hinge core utilizes a Φ18 mm precision stainless steel shaft. The core is CNC-machined and high-temperature hardened, achieving a surface hardness of HRC42-45. Axial play is controlled within 0.05 mm, ensuring smooth, wobble-free rotation. After 100,000 opening and closing cycles, the torque variation rate is less than 5%, effectively ensuring long-term stable operation.

Automatic Return

The hinge features a dual-spring structure with a rebound torque controlled between 1.8 and 2.2 Nm, automatically returning to the closed position within 90 degrees. This torque design, proven to withstand loads of 35 to 45 kg, ensures that bathroom partition doors close smoothly and automatically after opening, preventing ajarness and enhancing user convenience and privacy. The spring is made of fatigue-resistant steel wire, boasting a lifespan of over 150,000 cycles.

Reinforced Structure

The hinge body is 2 mm thick and formed using a single-piece stamping process, with no welds at the edges or corners, enhancing tensile strength and torsional resistance. According to static load tests, a single hinge can withstand a vertical load of up to 60 kg, and when installed in pairs, it can safely support a door weight of 120 kg.

Corrosion Resistance

When made of SUS316 stainless steel, its chloride pitting potential is over 60% higher than that of SUS304, allowing it to withstand 480 hours of continuous rust-free operation in an environment with 90% humidity and 5% salt spray. A satin finish forms a dense oxide protective layer, effectively resistant to corrosion from chemical cleaning agents.

Precise Installation

The hinge hole spacing is standardized, with a center-to-center distance of 36 mm, compatible with the hole positions of mainstream international partition systems. During installation, the door verticality can be fine-tuned using built-in adjustment holes, compensating for up to 3 mm of deviation. This structure improves construction efficiency and reduces installation deviation, ensuring uniform door gaps and a tight closure, enhancing overall aesthetics and sealing.

Public Bathroom Partitions

Widely used in public restroom partition doors. The hinges allow the door to close automatically, maintaining a clean and organized space. The stainless steel structure resists long-term moisture damage, extending its service life. Users experience smooth and quiet door opening and closing, reducing impact and noise, and enhancing overall restroom comfort.

Medical Facilities

Used in partition systems in hospitals and clinics, they effectively ensure automatic repositioning and closing of the door. Their corrosion resistance withstands medical cleaning agents and disinfectants, preventing surface oxidation and discoloration. The automatic return function reduces the frequency of door handle contact, improving hygiene standards and meeting the cleanliness requirements of medical environments.

Educational and Office Buildings

In public areas such as schools, the hinges maintain the door closed, preventing wind-induced swaying and damage. Their stable structure withstands frequent use and prevents loosening. The matte finish reduces glare, meeting the safety and visual comfort standards of campuses and offices.

Commercial Facilities and Stations

Used in high-traffic areas such as shopping malls, subway stations, and public restrooms, these hinges withstand frequent opening and closing, maintaining wear resistance and stability. Their automatic return design automatically closes the door after use, enhancing privacy and ensuring cleaning efficiency. The durable design reduces maintenance and lowers management costs.

Regular Cleaning

It is recommended to wipe the hinge surface with a neutral detergent and a soft cloth every two weeks to remove water stains and dirt, then rinse with clean water and dry. Avoid using chlorine-containing cleaners, as they may damage the stainless steel's passivation film. Keeping the surface clean prevents salt deposits, improving the hinge's corrosion resistance and finish.

Lubrication and Maintenance

Apply a small amount of waterproof lubricant to the hinge every three months to maintain smooth rotation and reduce friction noise. In high-use locations such as airports and shopping malls, maintenance should be reduced to every two months. Regular lubrication significantly extends the life of the hinge core and spring, maintaining a consistent opening force.

Screw Inspection

Check the tightness of the fixing screws every six months and re-tighten if necessary. Screws may become slightly loose due to prolonged use or vibration, affecting the door's closing accuracy. Regular inspections ensure proper door leaf alignment and prevent loosening that could cause hinge misalignment or door sagging.

Spring Return Test

It is recommended to test the spring return force annually. If the door returns slowly or cannot close completely, the internal spring assembly or the entire hinge set should be replaced promptly. Regular inspections can prevent doors from remaining open or returning unsteadily in public places, ensuring the safety and functionality of the partition system.
