A height adjustment method for sliding doors and windows

Abstract

The invention belongs to the technical field of door and window installation, and particularly relates to a height adjusting method of a sliding door and window. A pulley assembly adopted in the method comprises an outer frame and a pulley assembly body, the outer frame is mounted at the bottom of the door and window through screws, and sliding grooves are horizontally formed in the front and rearside walls of the outer frame; and the pulley assembly body comprises sliding blocks, supporting plates, pulleys, first springs and a cylinder assembly, the sliding blocks are located in the slidinggrooves in the front and rear side walls of the outer frame, the two sliding blocks are arranged in the same sliding groove, one end of each of the two sliding blocks is connected to the left and right side walls of the corresponding sliding groove through the first springs, the supporting plates are located in grooves of the outer frame, the two supporting plates are arranged as one set and aresymmetricalleft and right, the middles of the two supporting plates are hinged to the two sliding blocks respectively, the pulley is mounted at the bottom of each supporting plate, the cylinder assemblyis horizontally arranged between the two supporting plates, and the left and right ends of the cylinder assembly are hinged to the upper ends of the two supporting plates respectively. The height adjustment of the pulley assembly can be achieved through the swinging press of the door and window, and the installation and disassembly are convenient.

Description

technical field [0001] The invention belongs to the technical field of door and window installation, in particular to a method for adjusting the height of sliding doors and windows. Background technique [0002] In decoration, doors and windows are installed in the door frame on the wall through door and window accessories. The pulley is a commonly used door and window accessory, which is generally installed at the bottom or top of the door and window. Sliding makes it easier for people to push the doors and windows. Due to the different degrees of linear tolerance and non-right angle tolerance in the manufacturing process and installation process of doors and windows, sliding doors and windows will be derailed and stuck during use.

Problems solved by technology

Due to the different degrees of linear tolerance and non-right angle tolerance in the manufacturing process and installation process of doors and windows, sliding doors and windows will be derailed and stuck during use. Smooth movement, the upper part of the pulley assembly is connected with the door leaf or window sash, and the lower part slides along the ground rail with a pulley, but there are two kinds of existing door and window ground rail pulley assemblies, one is that the pulley is fixed and riveted on the pulley assembly, and its disadvantages are When in use, it cannot be swung up and down for automatic fine-tuning. When the ground rail is not completely level, the pulley on the pulley assembly cannot fully contact the ground rail. The danger of this kind of pulley assembly is gradually eliminated; the other is to install an inner shell mechanism in the pulley assembly, and the inner shell mechanism can be adjusted by swinging up and down. At present, the ground wheels on the market have oblique holes on the inner shell. There is a vertical hole at one end of the inner shell, but the angle of the ground wheel with this structure is not flexible to adjust up and down, and the angle of swing is small, and when the adjusting bolt is adjusted to the limit position, that is, the inner shell is adjusted to the lowest or highest position. state, the entire inner shell can only swing to one side, and cannot achieve the effect of seesaw swinging on both sides. It is difficult to accurately adjust the height of doors and windows, which reduces the quality of installation and affects subsequent use.
