Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, in particular to a door and window rear pulley mechanism with a boosting device and a door and window. Background Art

[0002] Existing rear pulleys for doors and windows do not have a good boosting device. When the door leaf is heavy, the thrust is large, and it is easy to cause the pulley to deviate, resulting in an unbalanced force on the entire door leaf, which in turn causes the pulley to be damaged, thereby affecting the normal use of the door and window. Utility Model Content

[0003] The utility model provides a door and window rear pulley mechanism with a boosting device and a door and window. The rear pulley mechanism of the utility model can save time and effort in operating the door and window main body, and maximizes the safety and service life of the pulley.

[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A door and window rear pulley mechanism with a boosting device comprises a rear pulley, a boosting device is arranged at the tail of the rear pulley, and the boosting device comprises a boosting rod, a boosting block and a base.

[0006] Furthermore, the booster rod is a hydraulic rod or a pneumatic rod.

[0007] Furthermore, both ends of the boost rod are connected to the boost block and the base by riveting or screws respectively.

[0008] Furthermore, the tail of the rear pulley is connected to the booster block.

[0009] Furthermore, the rear pulley tail and the booster block are connected by snap connection, riveting or screw connection.

[0010] A door and window using the above-mentioned door and window rear pulley mechanism comprises a door and window body, wherein the door and window rear pulley mechanism is arranged at the bottom of the door and window body and located at the rear end thereof. The base is connected to the profile by screws. Beneficial effects

[0011] The rear pulley mechanism of the utility model can save time and effort in operating the door and window main body by configuring the boosting device, thereby maximizing the safety and service life of the pulley. BRIEF DESCRIPTION OF THE DRAWINGS
