Description

Pulley adjustment device for mobile doors and windows

technical field

The utility model relates to a track type door and window installation assembly, in particular to a movable door and window pulley adjusting device.

Background technique

In the building decoration industry, the manufacture of aluminum or wooden doors requires the aluminum or wooden door to slide on the upper and lower tracks. Or the upper part of the wooden door leaf is equipped with an adjustable upper wheel, a rotating plate is riveted to the front end of a bottom plate, two pulleys are installed at both ends of the rotating plate, a traction plate is connected to one end of the rotating plate, and a pulley is connected to the other end of the traction plate There are screw holes on the ear plate, and a vertical ear plate is connected to one end of the bottom plate. There are screw holes on the vertical ear plate. A cross screw is installed between the two screw holes, and a boss is welded on the bottom plate. The inner side of the rotating plate at the bottom of the first pulley is an arc surface. When the cross screw is turned, the traction plate stretches the rotating plate and rotates around the boss, so that the linear distance between the two pulleys can be changed from narrow to wide, or from wide to wide. Narrowing, so that the wheel walls of the two pulleys are closely attached to the two inner walls of the upper track, ensuring smooth sliding of the aluminum door leaf or wooden door leaf. But this adjustment upper wheel structure is simple, not flexible enough, and assembly is not firm.

Aluminum alloy doors and windows or plastic steel door and window frames are often connected with corner brackets when they are spliced and installed. Attached drawings 1 and 2 show the relatively common aluminum automatic corner brackets and their installation methods on the door and window frames. . As shown in the figure, the corner code 9 is provided with two code nails 91 perpendicular to each other. When installing, first drill installation holes on the two frames of the frame body 8 to be installed, insert the code nail 91 in the installation hole, and then fasten the corner code 9, thereby the two frames 8 are fixedly connected. After the corner code was installed, the code nail stretched into the mounting groove 81 of the frame body. For some frames with shallow installation grooves, it is difficult to install the adjustable upper wheel due to the obstruction of the code nails.
