Description

Pulley for lifting sliding door and window

Technical Field

The utility model relates to the technical field of door and window pulleys, in particular to a pulley for lifting a sliding door and window.

Background

The pulley that current promotion sliding door when removing need remove through the pulley to the gum cover on the bearing of pulley is single groove, and the in-process pulley that removes takes place to rock easily, thereby makes the pulley take place to incline and leads to the door and window slope easily, and stability is relatively poor.

Disclosure of Invention

The utility model aims to solve the technical problem of poor stability in the prior art by providing a pulley for lifting a sliding door or window.

To achieve the above object, there is provided a pulley for lifting sliding doors and windows, comprising: the pulley assembly, the pulley assembly both sides are provided with two backplate, backplate lateral wall fixedly connected with fixed axle, the outside rotation of fixed axle is connected with the bearing, the gum cover has been cup jointed to the bearing outside, two recesses have been seted up on the gum cover outer circumference, set up two recesses on the outside gum cover of bearing, utilize two recesses and two slide rails to cooperate, make pulley assembly can keep stable when removing, avoid taking place the card.

According to the pulley for lifting the sliding door and window, the two inner walls of the grooves are matched with the sliding rail, and the outer walls of the sliding rail are in sliding connection with the inner walls of the grooves.

According to the pulley for lifting the sliding door and window, the inside of the bearing is rotationally connected with the outside of the fixed shaft.

Additional aspects and advantages of the utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.

The utility model aims to provide a pulley for lifting a sliding door and window, which mainly has the innovation points that:

the utility model utilizes the two grooves to be respectively matched with the two sliding rails, so that the pulley is kept stable in the moving process, the inclination is avoided, and the jamming of the door window and the sliding rails is avoided.
