Specifications And Selection of Fork Handles For Broken Bridge Aluminum Windows

As the core operating component of broken bridge aluminum windows, the fork handle undertakes multiple functions such as opening and closing, locking, and adjustment. Today, this article will discuss in depth the professional selection method of fork handles for broken bridge aluminum windows from the aspects of specification parameters, selection points, installation and maintenance.

I. Analysis of specification parameters of fork handles

The specification parameters of fork handles directly affect their performance and adaptability. The total length of standard fork handles is generally between 100-120mm, and the width of the fork opening is 12-14mm. These dimensions have been verified by long-term practice and can meet the use requirements of most broken bridge aluminum windows. Special specifications of fork handles need to be customized according to the specific window type. For example, narrow frame windows require shorter handles, while heavy windows require reinforced handles.

Material selection is the key factor in determining the service life of the handle. The surface of high-quality zinc alloy handles is treated with multi-layer electroplating, which has excellent corrosion resistance and a service life of more than 10 years. Although stainless steel is more expensive, it performs better in highly corrosive environments such as coastal areas. The surface treatment process not only affects the aesthetics, but also the durability of the handle. A good surface treatment can effectively prevent fading and wear.

Mechanical properties are an important indicator for measuring the quality of handles. The torsional strength of a high-quality handle should reach more than 50N·m, and the number of repeated opening and closing times can reach more than 50,000 times. These parameters directly affect the service life and operating feel of the handle, and should be focused on when selecting.

2. Scientific selection method of fork handles

The type of window determines the selection of handles. Casement windows need to choose handles with larger operating torque to ensure the sealing of the windows; sliding windows need to choose handles with light operation for daily use. For heavy windows, it is recommended to choose reinforced handles to ensure smooth operation and safe use.

The use environment is an important consideration for selection. In coastal areas or high humidity environments, stainless steel or handles with special anti-corrosion treatment should be preferred. In areas with large temperature differences, materials with small thermal expansion and contraction coefficients need to be selected to prevent deformation or failure of the handles.

Safety is an important indicator for the selection of handles. High-quality fork handles should have an anti-pry design and a reasonable distribution of locking points, which can effectively improve the overall safety of the window. At the same time, the operating force of the handle should be moderate, ensuring that children cannot open it easily and that it is convenient for adults to operate it daily.

III. Key points for the installation and maintenance of fork handles

The installation accuracy directly affects the performance of the handle. During installation, it is necessary to ensure that the clearance between the handle and the transmission is within 0.5mm. Too large a clearance will cause unsmooth operation, and too small a clearance will increase wear. The installation angle should be strictly controlled at 90 degrees, and the deviation should not exceed 2 degrees.

Daily maintenance is the key to extending the service life of the handle. It is recommended to clean and lubricate the handle every six months, and use special lubricants to maintain the rotating parts. Avoid using corrosive detergents to prevent damage to the surface treatment layer.

Professional methods are required for troubleshooting. When the operation is not smooth, check whether the transmission system is deformed or loose, and do not force the operation. Damaged handles should be replaced in time to avoid affecting the overall performance of the window.

The scientific selection and correct use of the fork handle not only affects the performance of the thermally-insulated aluminum window, but also affects the overall quality of the building.
