Window frame to prevent dust from entering the chute

Abstract

The invention discloses a window frame preventing dust from entering a slide groove. The window frame preventing dust from entering the slide groove comprises a window frame body and a window. The slide groove is formed in the bottom of the window frame body, and two zipper tapes are arranged at the two sides of the slide groove correspondingly and matched with each other. Two zipper heads in a reversed direction are arranged at the zipper tapes, the window is arranged between the two zipper tapes, and fixed structures used for fixing the zipper heads are arranged at the two sides of the window. Grooves holding zipper teeth of the zipper tapes are formed in the two sides of the window, guide grooves are formed in the upper and lower sides of the zipper teeth, and guide raised lines matched with the guide grooves are arranged at the two sides of the grooves downwards. By adoption of the structure in the process of moving the window, the zipper head at the front of the forward direction of the window separates the two zipper tapes and the zipper head at the back of the forward direction of the window locks the two zipper tapes, thereby making the slide groove sealed by the zipper tapes all the time, preventing the dust from entering zippers, and preventing dust and impurities from affecting the sliding of the window.

Description

technical field [0001] The invention belongs to the technical field of alloy window frames, in particular to a window frame for preventing dust from entering a chute. Background technique [0002] The window frame is the transition layer between the wall and the window, which plays a role in fixing and preventing the surrounding walls from collapsing. There is a chute at the bottom of the window frame, and the window slides in the chute. Since the chute is isolated into multiple areas, it is difficult to remove the dust and impurities in the chute. If things go on like this, it is necessary to manually remove the impurities in the chute, otherwise the It will cause the window to not open and close smoothly. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a window frame that prevents dust from entering the chute. This structure can keep the chute in a closed state when the window is sliding, thereby preventing ...
