Referring to fig. 1 to 2, the curtain rail according to the embodiment of the present invention includes a rail frame 10, wherein lower portions of two sides of the rail frame 10 respectively extend inward to form sliding tables 11, and a hanger frame 20 can pass through between the two sliding tables 11. The top surface of the sliding table 11 is provided with a groove 110 arranged along the sliding direction, the groove 110 includes a first sliding surface 111 and a second sliding surface 112, the first sliding surface 111 and the second sliding surface 112 are respectively located at two sides of the lowest position 113 of the groove 110, and the first sliding surface 111 and the second sliding surface 112 are respectively used for abutting against the rolling members 21. Because the rolling member 21 rolls along the groove 110, the groove 110 has a certain limiting effect on the rolling member 21, and the horizontal transverse displacement of the rolling member 21 in the rolling process is avoided, so that the friction is increased, and even the damage and the noise are caused.

As an alternative embodiment, referring to fig. 2, the first sliding surface 111 and the second sliding surface 112 are both flat surfaces, and the first sliding surface 111 and the second sliding surface 112 are connected at an obtuse angle. The bottom end of the first sliding surface 111 and the bottom end of the second sliding surface 112 are joined to form an obtuse-angle-shaped opening which is opposed to the parting line 212 of the roller 21; the parting line 212 of the roller 21 is located above the lowest portion 113 of the groove 110, and the roller 21 does not contact the first sliding surface 111 or the second sliding surface 112, thereby preventing the parting line 212 of the roller 21 from directly rolling-contacting the first sliding surface 111 or the second sliding surface 112 of the groove 110, which causes noise.

As another optional embodiment, the first sliding surface 111 and the second sliding surface 112 are both arc surfaces, the first sliding surface 111 and the second sliding surface 112 are connected in an arc, and optionally, the first sliding surface 111 and the second sliding surface 112 are connected to form a complete arc surface. Likewise, the parting line 212 of the roller 21 is located above the lowest part 113 of the groove, and the roller 21 does not contact the first sliding surface 111 or the second sliding surface 112, thereby preventing the parting line 212 of the roller 21 from directly rolling-contacting the first sliding surface 111 or the second sliding surface 112 of the groove 110, which causes noise.

Furthermore, the first sliding surface 111 and the second sliding surface 112 are symmetrically arranged, so that the two rolling surfaces 211 of the roller 21, which are respectively abutted against the first sliding surface 111 and the second sliding surface 112, are uniformly stressed, and the condition of excessive wear due to uneven stress is prevented.

Referring to fig. 1, the curtain rail assembly according to the embodiment of the present invention includes the curtain rail and a plurality of hanger frames 20. The two sides of the hanger bracket 20 are respectively provided with a rolling member 21, the bottom of the hanger bracket 20 is provided with a hanging wheel 23, in the embodiment, the rolling members 21 are rollers. The wheel hanger 20 can extend between the two sliding tables 11, and the two rolling members 21 of each wheel hanger 20 correspond to the two grooves 110 of the track frame 10 one by one, i.e. for a single wheel hanger 20, the two rolling members 21 of the wheel hanger 20 correspond to the two grooves 110 one by one, respectively. The rolling elements 21 roll along the grooves 110, in particular, the rolling elements 21 abut against the first sliding surface 111 and the second sliding surface 112 of the respective groove 110, the lowest part 113 of the groove 110 is opposite to the parting line 212 of the rolling elements 21, and a gap is provided between the lowest part 113 of the groove 110 and the parting line 212 of the rolling elements 21, i.e., the groove 110 is spaced from the parting line 212 of the rolling elements 21.

Preferably, referring to fig. 3, the rolling surface 211 of the rolling member 21 abutting against the first sliding surface 111 is an arc surface, and the rolling surface of the rolling member 21 abutting against the second sliding surface 112 is an arc surface, so as to better adapt to different grooves 110, and in addition, the rolling member 21 and the first sliding surface 111 can be ensured to be in point contact or line contact, so as to reduce the generation of noise; the contact of the rolling elements 21 with the second sliding surface 112 is the same.

The embodiment of the utility model provides a curtain, it includes curtain cloth and curtain rail set spare, and curtain cloth is connected with hanging wheel 23. Furthermore, the top of the hanger 20 is provided with a fastening slot 22 for installing a wire buckle, and after the wire buckle is installed on the fastening slot 22, all the wire buckles are strung up by using a wire, so that the distance between two adjacent hangers 20 can be maintained, and collision can be prevented.
