Door and Window Hardware Accessories General Knowledge - 钧记五金知识讲堂(2)

As the living environment and living space are increasingly concerned and valued, as a relatively independent and complete architectural original, the role and position of the door and window system in the entire building has been significantly improved. Many important functions of the door and window system are achieved through hardware accessories. China's door and window hardware industry has continued to innovate for many years, which has effectively promoted the performance improvement and function innovation of the door and window system. This article will use Wuhan Min Kee hardware accessories as an example to introduce the technical innovations in the aspects of product development, design, production and application of door and window hardware accessories in recent years in terms of comfort, security and intelligence.
1.Comfort degree: The multi-point locking system with reasonable hardware design gives the doors and windows the best sealing, thermal insulation and noise reduction performance, creating a quiet and comfortable living space; through the compact structure of the transmission and operating devices, to achieve Diversified opening and ventilation of doors and windows. Flat open and flat open are classic open methods that have been popular for decades. Based on this, a variety of auxiliary and special opening methods have been derived, such as micro slit ventilation (providing 45 degree ventilation slots). Tilt flat open (opposite to the traditional flat open and tilt open order), lift push and pull tilt (applicable to large opening fan), full hidden hinge, high window opening, middling flip, etc.; user-friendly product design , Gives the end user of the door and window a comfortable feel and convenient operation, such as lifting fan protection (freely closing the sash, preventing the window sash from sagging), preventing misoperation (to avoid damage and danger caused by wrong actions), squatting type introduction device (from Tilting position is more effortless and convenient when closing doors and windows, especially for high windows, silent tongues (to eliminate collision noise when closing doors), auxiliary functions built into hands, and other additional functions (open limit, tilt Turn positioning, etc.).
Large opening fan push-pull system: Lifting push-pull and push-pull tilting doors are designed for the free division of indoor space and the communication and integration of living room and nature. The push-pull mechanism, which is controlled by the handle, can easily perform the push-pull open-close operation without wearing the sealant. The unique low threshold design allows children's bikes and disabled vehicles to easily cross.
2. The safety (security) of security doors and windows is getting more and more attention. In order to meet the requirements of different buildings for security and anti-theft performance, we have introduced strict anti-theft grade standards, from the configuration of anti-theft locks to complete testing methods and procedures.
For windows, the typical anti-theft lock design introduced by China's hardware manufacturers, in order to prevent the sash from being lifted in the tilted state, adds a horizontal tilting locking bar under the sash, which significantly improves the security level of the entire window. .
In addition, in order to improve the safe use of doors and windows, the anti-misoperation function has become a standard configuration of doors and windows. In addition, adding the locking function (pressing the lock or the lock cylinder) and installing the accessories with the locking function in the handle can improve the safe use and the anti-theft performance of the doors and windows to varying degrees. For example, the hardware production handle can be divided into separate open and close handles and non-separate open and close handles, in which the seven-character handles can be individually locked.
3. The concept of intelligent and intelligent doors and windows is naturally produced along with the humanization and digitization of human society. The intelligentization of doors and windows reflects the future of the development of the doors and windows industry.
The main connotations of smart doors and windows include the following aspects:
Replacement of the handle operation by the motor drive to achieve the opening and closing of doors and windows. This is a prerequisite for automatic control.
Sensors are installed at the lock points or outdoors to collect data on door opening/closing status and external climate parameters. Through the use and processing of these data, the monitoring of opening and closing of doors and windows of buildings and the coordinated control of air conditioning heating systems are realized. The automatic control of opening and closing of doors and windows through programming or network, opening and closing doors and windows according to user's specific requirements (time, interval or outside conditions) to realize personalized and intelligent ventilation of doors and windows, is an organic component of the intelligent human environment. section.
