The pulley base is arranged into the cavity of the body, and the wheels are arranged in the pulley base. One end of the body is provided with tightening adjusting screws which are tightened with the door and window, an oblique slope is installed on the bottom of the cavity of the body, and an oblique slope is correspondingly arranged on the bottom of the pulley base, as well as a height adjusting screw is arranged between the body and the pulley base. The utility model has the advantages of easy to assemble and disassemble, suitable for assembling door and window, flexible and simple in operation; the utility model also has simple and reasonable structure, and the height of the pulley can be adjusted timely.
Description
One, technical field
The utility model relates to a kind of door and window assembly, is used for the assembly pulley that door and window is moved in push-and-pull on particularly a kind of frame that is contained in door and window.
Two, background technology
The employed door and windows of building such as modern room, hotel, office building mostly are the push-pull door and window that aluminium alloys, plastic-steel or other materials are made, promptly door and window in orbit move left and right and or close or open.This door and window is directly by in groove, the protruding stupefied embedding doorframe track, and some installs pulley on the base of door and window, moves in orbit by pulley.The former moves effort, and the door and window wearing and tearing are big, and the employed pulley of the latter is not an individual member, but is fixed on the door and window, and the installing/dismounting inconvenience is particularly more inconvenient for the assembling type door-window installation, and the height of pulley can not be regulated.
Three, summary of the invention
1, goal of the invention: the purpose of this utility model provides a kind of nimble, easy installation and removal, height-adjustable door and window assembly pulley of moving.
2, technical scheme: for achieving the above object, assembly pulley described in the utility model is characterized in that it comprises body, pulley base and wheel, and pulley base places in the cavity of body, wheel is contained in the pulley base, an end of body be provided with make body with the fastening fastening adjustment screws of the door and window of adorning.
Middle part, cavity bottom surface at described body is provided with the bottom surface, slope, is provided with corresponding slope in the bottom surface of corresponding pulley base, is provided with bearing pin between two slopes, between the same end of body and pulley base, is provided with the height adjustment screw that pulley base is moved along slope.
Operating principle of the present utility model is: assembly pulley is embedded in the section bar notch of door and window bottom, the rotation fastening adjustment screws is fixed assembly pulley and door and window, again rotation height adjustment screw, along moving on the slope, body cavity bottom surface, regulate the height of pulley by pulley base.
3, beneficial effect: the utility model compared with prior art, its remarkable advantage is: 1, easy installation and removal is suitable for assembling type door-window; 2, flexible operation, convenience; But the height of 3 timely adjustment pulleys is with the elasticity of control door and window in doorframe; 4, simple in structure, reasonable in design.
