[0036] The guide rail profile 12 can be fixed to the guide rail frame 11 and the adjacent guide rail profile 12 by screws, etc. The sliding groove 13 is arranged between the two guide rail grooves 14 to accommodate a sliding member sliding on the guide rail profile 12. The guide rail groove 14 is for the sliding member to slide along the guide rail profile 12. When the guide rail profile 12 is set to multiple, it can slide in conjunction with multiple sliding members. Compared with the traditional guide rail structure in which multiple guide rails are set on an integral profile, the guide rail structure 10 can increase or decrease the number of guide rail profiles 12 according to actual needs, thereby determining the number of guide rails, which can meet the personalized needs of customers. At the same time, for manufacturers, only one size of guide rail profile 12 needs to be processed to meet the various needs of customers, which is more economical.

[0037] The guide rail frame 11 includes two symmetrically arranged bracket profiles 111 . The bracket profile 111 includes a supporting portion 1111 and a fixing portion 1112 . The guide rail profile 12 is fixed between the two supporting portions 1111 . The fixing portion 1112 is provided on the bottom outer side of the supporting portion 1111 .

[0038] The two bracket profiles 111 are connected and supported together by the middle guide rail profile 12. The two bracket profiles 111 have the same structure and are symmetrically positioned relative to the guide rail profile 12, making assembly simpler. The fixing portion 1112 is located outside the supporting portion 1111 and will not affect the operation of the pulley assembly 20.

[0039] An extension plate 1113 is provided on the inner side of the bottom of the support portion 1111 . The extension plates 1113 on the two support portions 1111 do not touch each other, and the support rod 21 extends out of the bottom of the guide rail frame 11 from the gap between the two extension plates 1113 .

[0040] The guide rail frame 11 is hollow inside, and a support seat 16 is fixed inside the guide rail frame 11 . The support seat 16 is arranged on the top of the guide rail profile 12 , and the bottom of the guide rail profile 12 does not contact the bottom wall of the guide rail frame 11 .

[0041] Since the two bracket profiles 111 are symmetrically arranged relative to the guide rail profile 12, the two bracket profiles 111 do not touch each other, so the interior of the guide rail frame 11 is hollow, and the support seat 16 and the guide rail profile 12 are both fixed in the guide rail frame 11. The support seat 16 is used to fix and support the positions of the two bracket profiles 111, which can prevent the two bracket profiles 111 from deforming, avoid the bracket profile 111 from squeezing the guide rail profile 12, and increase the stability of the guide rail structure 10.

[0042] Example 2

[0043] like Figures 1 to 11 As shown, this embodiment provides a sliding pocket door, including a sliding door leaf 30, a pulley assembly 20 and the guide rail structure 10 of Example 1.

The two pulleys 22 slide in two guide rail grooves 14 respectively. The support rod 21 passes through the sliding groove 13 and the accommodating hole 15 and extends from the bottom of the guide rail frame 11. The bottom of the extended support rod 21 is fixed to the top end of the sliding door leaf 30.

[0044] The sliding groove 13 is arranged between the two guide rail grooves 14 to accommodate the top of the support rod 21. The top of the support rod 21 can only move in the sliding groove 13. The sliding groove 13 guides the movement of the top of the support rod 21. The pulley 22 is confined in the guide rail groove 14 and can only slide along the guide rail groove 14. The guide rail groove 14 also guides the movement of the pulley 22. Under the joint guidance of the sliding groove 13 and the guide rail groove 14, the pulley assembly 20 can move steadily in the guide rail structure 10 without any jamming problems.

[0045] When the sliding door leaf 30 is pushed with force, the support rod 21 and the pulley 22 can be driven to slide along the length direction of the guide rail structure 10, thereby achieving a pushing and pulling effect.

[0046] A rotating shaft 23 is provided on both sides of the top of the support rod 21, and the pulley 22 is provided on the rotating shaft 23. As a preferred embodiment, the rotating shaft 23 is fixed on both sides of the top of the support rod 21, and the pulley 22 can rotate relative to the rotating shaft 23, thereby realizing the movement of the pulley 22 in the guide rail groove 14.

[0047] The sliding pocket door also includes a fixed door leaf 40, which is arranged below the guide rail structure 10.
