Hollow section sliding sash with disappearing screen window

Abstract

A sliding window made of hollow section and with hidden screen window is composed of a window frame made of hollow section, glass window sashes, and hidden screen window installed in window frame. Its advantages are high strength, good sealing performance, low cost and beautiful appearance.

Description

technical field [0001] The invention relates to a push-pull hollow profile window with an invisible screen window made of a hollow profile with a special cross section. Background technique [0002] Since the advent of plastic or plastic-steel sliding windows with invisible screens, screens do not take up extra space, are very convenient to install and use, are simple, beautiful and practical, and are loved by people. The market prospect is promising, so many manufacturers are committed to design and development Produce more reasonable and perfect new products. At present, the more advanced way of placing invisible screens is to roll the screens in the window frame. Such as the Chinese patent whose patent No. is 96231490.0, it is to be designed into two parts by the window frame that needs to place the window screen, and a part is designed as a cross-section as a trapezoidal substrate, and the other part is designed as a cross-section that is an L-shaped cover, and the cove...

Problems solved by technology

In the structural composition of the sliding window, the functions of the upper frame, the lower frame and the side frame are not the same. It coincides with the side frame of the window sash, etc., so their respective structures are not the same, which brings a series of negative effects on the production, economy and performance of the sliding window, and in this patent, because the two sides Due to the modification of one side of the frame, the structure of the two sides of the frame is also different, which aggravates the negative impact

The negative effects described are: 1. Different window frames need to use profiles of different structures, which reduces the versatility of the profiles and increases the cost of molds for the production of profiles. The price of profiles is higher, which directly increases the production cost; 2. Different profiles are used in production, which has high requirements for production equipment and operators, and the production process is relatively complicated; 3. Since the length of each window frame is generally inconsistent, and the length of profiles is usually constant, it is not conducive to the rational use of profiles; 4. Due to the different structure of the profiles used in each window frame, the matching degree of the welding surface is poor, which directly leads to low welding strength, which affects the strength of the entire sliding window and other aspects of performance
