Description

Technical Field

[0001] The utility model belongs to the technical field of curtain tracks, and particularly relates to a track structure with multiple silent strips. Background Art

[0002] At present, most curtain tracks are extruded from aluminum alloy materials. When the running beads slide, they will come into contact with the curtain track, so when the running beads rub against the curtain track, it will generate a relatively large noise, which will also affect the smoothness of the running beads sliding. And when the running beads slide, they will shake, thus coming into contact with the inner wall of the curtain track, affecting the normal use of users.

[0003] In order to solve the deficiencies of the existing technology, people have carried out long-term explorations and put forward various solutions. For example, a Chinese patent document discloses a splicing structure for preventing jamming of a dream curtain track [202321102544.X], which includes a track profile with a track opening on one side for the trolley and / or running beads to be movably arranged. Inside the side of the track profile with the track opening, there is at least one installation groove located at the side of the track opening, and the installation groove extends along the axial direction of the track profile. A silent strip body that extends above the notch of the installation groove and can be slidably arranged with the trolley and / or running beads is inserted into the installation groove, and the silent strip body is installed in the installation groove through a support and positioning structure.
