We have always taken the unified expressionof high-end residential comfort needs and architectural aesthetics as the coreof our research and development. Collaborating closely with our Italian R&Dand design team, we have deeply led the full-dimensional definition of ourproducts. Adhering to the design philosophy of high-end minimalism across allaspects, we have deeply integrated functional innovation, structural safety,and facade aesthetics. We have launched a new generation of panoramic slidingdoors equipped with exclusive micro-ventilation limit devices, creating amicro-ventilation solution that balances safety, comfort, and quality formodern high-end luxury homes. This design has been applied for a nationalutility model invention patent - Patent No.: 2026209131891

全系列全景推拉门产品可配置微通风限位装置，采用限位锁止设计，支持一键触发微通风模式，操作逻辑简洁直观，充分适配居家场景下的高频使用需求。该装置依托精密机械传动结构，实现窗扇开启距离2-12cm区间的精准限位，用户可根据室内换气需求、室外温湿度与风力条件灵活定制开启幅度，在保障室内空气有序对流置换的同时，从结构根源上规避了推拉门开启状态下带来的安全隐患，让居家日常更稳妥。

The full series of panoramic sliding doorproducts can be equipped with a micro-ventilation limit device, featuring alimit lock design that supports one-button triggering of the micro-ventilationmode. The operation logic is simple and intuitive, fully adapting to thehigh-frequency usage demands in home scenarios. Relying on a precise mechanicaltransmission structure, this device achieves accurate limiting of the windowsash opening distance within a range of 2-12cm. Users can flexibly customizethe opening amplitude according to indoor ventilation needs, outdoortemperature and humidity, and wind conditions. While ensuring orderly airconvection and replacement inside the room, it structurally eliminatespotential safety hazards associated with the sliding door when it is open,making daily home life more secure.

针对居家防盗与儿童防护场景，该限位系统采用室内专属操作逻辑，室外侧无任何可撬动、可操控的开启点位，无法通过室外完成推拉门开启动作，构筑起被动式安全防盗屏障。

For home security and child protectionscenarios, this limit system adopts an indoor-exclusive operation logic. Thereare no pryable or operable opening points on the outdoor side, making itimpossible to open the sliding door from the outside. This establishes apassive security barrier against theft.

在微开启、微通风的使用状态下，既能实现室内外空气的持续轻柔置换，避免大风直吹的不适感，又能全程维持稳定的安全防护属性，真正做到通风、防蚊、安全皆不误。

In the state of micro-opening andmicro-ventilation, it can not only achieve continuous and gentle exchange ofindoor and outdoor air, avoiding the discomfort of direct strong winds, butalso maintain stable safety protection properties throughout the process, trulyachieving ventilation, mosquito prevention, and safety without compromise.

整套限位装置采用内嵌式集成布局，室外侧无外露五金、无突兀结构断点，严格遵循全案高端极简的视觉准则，完整保留了全景推拉门立面的整洁质感与建筑外观的整体性，将功能创新完全隐匿于极简美学之中。

Theentire set of limit devices adopts an embedded integrated layout, with noexposed hardware or abrupt structural discontinuities on the outdoor side. Itstrictly follows the high-end and minimalist visual guidelines of the overalldesign, fully preserving the clean and sleek texture of the panoramic slidingdoor facade and the integrity of the building's exterior. The functionalinnovation is completely concealed within the minimalist aesthetic.

从意大利研发设计团队对人居生活细节的深度考量，到国际品牌贯穿全生产链路的精工品控标准，再到全案高端极简设计理念在每一处构件的落地执行，这套全景推拉门微通风限位装置不仅是一项功能配置，更是高端门窗“功能融于美学、安全藏于日常”设计理念的具象化，为当代高端豪宅门窗系统树立了舒适与安全并重的品质标杆。

From thedeep consideration of the Italian R&D and design team towards the detailsof human living, to the precision quality control standards of internationalbrands throughout the entire production chain, and to the implementation of thehigh-end minimalist design concept in every component, this panoramic slidingdoor micro-ventilation limiter is not only a functional configuration, but alsoa materialization of the design concept of "function integrated intoaesthetics, safety hidden in daily life" for high-end doors and windows.It sets a quality benchmark for contemporary high-end luxury home door andwindow systems that emphasizes both comfort and safety.
