Technical Field

The invention belongs to the technical field of sliding door pulleys, and particularly relates to a pulley for a sliding door.

Background

The sliding seat is an accessory of a modern sliding door and window and is designed for back and forth movement of a door leaf and a window sash, but the sliding seat pulley of the existing sliding door and window is not high in bearing and poor in smooth degree effect, so that the problem needs to be solved by designing a pulley for the sliding door.

Disclosure of Invention

The present invention is directed to a pulley for a sliding door, which solves the above-mentioned problems of the prior art.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a pulley for push-and-pull door, includes shell and inner shell, the inner shell embedding is in the inside of shell, the inside of inner shell is connected with the bearing pulley through pulley accessory two and pulley accessory one, the one end of shell is provided with the nut, the nut passes through the screw and is connected with the shell, the shell passes through outer nail and is connected with the inner shell, the inside one end that is close to the screw of shell is provided with the card, and the screw cooperation is used.

Preferably, the two bearing pulleys are symmetrically arranged and are in rolling connection in the inner shell.

Preferably, the screw penetrates through the shell and the clamping piece to be in threaded connection with the nut.

The invention has the technical effects and advantages that: this pulley for sliding door through setting up the linkage relation between bearing pulley, outer nail, card, shell, screw, pulley accessory one, nut, pulley accessory two and the inner shell for this pulley bearing is effectual, and the smoothness improves moreover, and simple structure is fit for using widely.
