Problems solved by technology

[0002] At present, whether it is plastic steel or aluminum alloy doors and windows on the market, the doors and windows are supported by the pulleys in the bottom grooves, so that they can be moved easily. The doors are not processed in parallel, so that the force on the pulleys at both ends is even, and the pulley at the end with a large force surface is very easy to damage, resulting in frequent maintenance. If it is not repaired in time, it will directly affect the use. The chute is not parallel. In fact, one roller is still working, and the gravity it bears is relatively large, especially for plastic steel doors or doors and windows filled with fillers in plastic steel doors, which appear to be heavier, which makes it difficult for one roller to bear. Doors and windows are difficult to move due to a broken roller, which affects people's daily life.

Embodiment Construction

[0006] The present invention will be further described below in conjunction with accompanying drawing:

[0007] See accompanying drawing 1, the roller shaft (2) at both ends of the roller frame (5) passes through the roller (1) flexibly, and the roller shaft (2) is fixedly connected with the roller frame (5) to form a pulley; the balance shaft ( 6) pass through the connecting hole at the upper end of the roller frame (5) to form a flexible connection, and the two ends of the balance shaft (6) are fixed on both sides of the balance frame (3).

[0008] See attached drawing 1, the roller shaft (2) at both ends of the roller frame (5) passes through the roller (1) flexibly, and the two ends of the roller shaft (2) and the roller frame (5) are riveted to achieve a fixed connection , forming a pulley; the balance shaft (6) passes through the connecting hole at the upper end of the roller frame (5) to form a flexible connection, and the two ends of the balance shaft (6) are fixed on ...

Abstract

The invention relates to a balanced type double pulley, which comprises a roller, a roller shaft and a roller frame, wherein a balanced shaft which is fixed on a balanced frame is moveably connected with the roller frame, and both ends of the balanced frame are provided with mounting holes. The balanced type double pulley overcomes the phenomenon that a single roller is forced which is caused by that two roller shaft centers are not parallel to a chute or a door and a window frame are not parallel. Thereby reducing maintaining times, the events that a door and a window are hard to move, which are caused by that a roller is damaged to influence human daily life can not happen.

Description

1. Technical field: [0001] The invention relates to a balanced double pulley, which relates to the technical field of architectural hardware components and is applied to doors and windows. 2. Background technology: [0002] At present, whether it is plastic steel or aluminum alloy doors and windows on the market, the doors and windows are supported by the pulleys in the bottom grooves, so that they can be moved easily. The doors are not processed in parallel, so that the force on the pulleys at both ends is even, and the pulley at the end with a large force surface is very easy to damage, resulting in frequent maintenance. If it is not repaired in time, it will directly affect the use. The chute is not parallel. In fact, one roller is still working, and the gravity it bears is relatively large, especially for plastic steel doors or doors and windows filled with fillers in plastic steel doors, which appear to be heavier, which makes it difficult for one roller to bear.
