Curtain tracks are important accessories for hanging curtains. However, due to the limitations of existing technology, existing curtain tracks have the following shortcomings and deficiencies:

[0003] 1. Curtains are divided into two types according to their production methods. One is hook-type curtains, which are suitable for curtain tracks and Roman rods with hook rings. The other is punched curtains, which are only suitable for Roman rods. In comparison, hook-type curtains are the preferred choice of most families due to their simple shape and easy disassembly and washing. Limited by existing technology, the pulley grooves and pulleys of existing curtain tracks are all vertically facing downwards. The track and the curtain must keep a distance and cannot touch each other. Similarly, the hook-type Roman rod and the curtain must keep a distance and cannot touch each other, otherwise it will affect the normal pulling of the curtain, causing light leakage between the existing hook-type track or Roman rod and the curtain, affecting the shielding and privacy of the curtain.

[0033] The embodiments of the technical scheme of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the present application, therefore only as an example, and cannot limit the protection scope of the present application.

[0034] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be the usual meaning understood by the technical personnel skilled in the art to which the present application belongs.

[0035] As Figure 1 shown, the present application provides a three-track integrated curtain track and assembly, comprising a track 1, a sealing element 5, an installation code 4 and 6, a roller 2, a pulley 3.

[0036] As Figure 4As shown, the track has one track and three grooves 111, 112, 12 and openings at both ends. The roller 2 enters and exits the two roller grooves 111 and 112 in the middle of the track 1 through the openings, and the pulley 3 enters and exits the pulley groove 12 at the bottom of the track 1 through the openings.

[0037] like Figures 3 to 5 and Figure 9 As shown, the two roller grooves 111 and 112 in the middle of the track 1 are polygonal side track structures extending along the length of the track 1. The two roller grooves 111 and 112 are respectively arranged with multiple rollers 2 at intervals. The four roller wheels 22 of the roller 2 are respectively pressed against the four side tracks 1112 and 1122 at a vertical angle to the four roller wheels 22. On the track 1, the four roller wheels 22 of the roller 2 in the two roller grooves 111 and 112 are respectively fitted and pressed on four side roads 1112 and 1122 of the polygonal side road structure of the roller grooves 111 and 112, and roll left and right. The roller hanging arms 21 of the rollers 2 in the two roller grooves 111 and 112 in the middle of the track 1 extend laterally out of the roller groove notches 1111 and 1121 in the opposite direction. The roller hanging arms 21 are suspended without contacting the track 1. After the curtain is hung on the roller hanging ring 23 arranged at the top of the roller hanging arm 21, the curtain covers the lower half A of the track 1, solving the light leakage problem between the curtain and the track in the prior art.

[0039] like Figures 1 to 3 As shown, notches 512 are provided on both sides of the main head 51 to enclose the roller arms 21. The roller arms 21 at the outermost ends of the two roller grooves 111 and 112 in the middle of the track 1 are placed between the main head 51 and the auxiliary head 52. The main head 51 and the auxiliary head 52 are each provided with screw holes. The main head 51 and the auxiliary head 52 are connected to the connecting member 53 via screws on the connecting member 53. The rollers 2 at the outermost ends of the roller grooves 111 and 112 of the track 1 are fixed in the sealing member 5. After the curtains are mounted, they will not move left or right when pulled, preventing light leakage from the curtains at the ends of the two roller grooves 111 and 112 in the middle of the track 1. The main head hanging ring 511 is used to fix the curtains at both ends of the pulley groove 12. After the curtains are mounted, they will not move left or right when pulled, preventing light leakage from the curtains at both ends of the pulley groove 12 at the bottom of the track 1.

[0040] like Figure 4 and Figure 8 As shown, the spring buckle of the top mounting bracket 4 is snapped into the mounting bracket slot 13 of the track 1, and then the track 1 is installed in the curtain box or on the ceiling.

[0041] As Figure 7 and Figure 9 As shown in the wall-mounted code 6 for installing the track 1 to the wall, first install the support body 61 of the wall-mounted code to the wall, then install the code card slot 13 on one side of the track 1 into the hanging ear 611 of the support body 61, and then insert the code card slot 13 on the other side of the track 1 into the fixed block 621, and then use the screw 631 to fix the track 1 and the fixed block 621 to the support body 61. The design of the wall-mounted code 6 facilitates the installation of the track 1 to the wall position.
