Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1 - 4 shown, the present utility model provides a technical solution:

[0026] An upper sliding rail structure for a suspended rail door, including an upper sliding rail 1, which is arranged on the ceiling keel of the door frame and is used to guide the opening and closing path of the suspended rail door. The upper sliding rail 1 includes a front sliding rail 11 and a rear sliding rail 12, which are connected to each other. And sliding grooves 13 are opened on the lower sides of the front sliding rail 11 and the rear sliding rail 12. A strengthening component is arranged outside the sliding grooves 13. Moving components are slidably arranged in the sliding grooves 13. The lower sides of the moving components are connected to the upper block of the fan 2 through connection components. The upper block of the fan 2 is used to connect the door panel of the suspended rail door. Through the front and rear arrangement of the front sliding rail 11 and the rear sliding rail 12 and connecting different door panels respectively, the two suspended rail doors can slide relative to each other to realize the opening and closing function of the door.

[0027] In this embodiment, a first partition cavity 3 is provided at the connection between the front slide rail 11 and the rear slide rail 12, and a second partition cavity 4 is provided on the side of the rear slide rail 12 away from the front slide rail 11. Sound insulation and heat insulation components such as foam can be filled in the first partition cavity 3 and the second partition cavity 4 to reduce the volume of noise generated by the moving component when the hanging rail door opens and closes, and the practicability is better. Connection plates 5 are provided on the outer sides of the tops of the front slide rail 11 and the outer side of the top of the second partition cavity 4. The connection plates 5 are used to connect the ceiling keel, and the connection plates 5 and the ceiling keel are fixedly connected by connection bolts or fixing screws; connection plates 5 can also be provided on the top of the rear slide rail 12 and the outer side of the top of the second partition cavity 4, but the stability of providing connection plates 5 on the outer sides of the tops of the front slide rail 11 and the outer side of the top of the second partition cavity 4 is better.

[0028] In this embodiment, sliding ribs 18 are provided on both sides inside the chute 13. The sliding ribs 18 are used to contact the moving component, and the surface of the sliding rib 18 in contact with the moving component is set as a convex arc surface to reduce the friction between the sliding rib 18 and the moving component, making it easier to open and close the hanging rail door, reducing the friction and wear conditions, and extending the service life.

[0029] In this embodiment, the strengthening component includes a strengthening rib 6 and a supporting rib 7. The strengthening rib 6 is provided on the outer side of the side wall of the chute 13, that is, on the outer side of the end of the sliding rib 18 away from the moving component. One side of the strengthening rib 6 is connected to the side wall of the chute 13, and the other side of the strengthening rib 6 is connected to one side of the supporting rib 7. The side of the supporting rib 7 away from the strengthening rib 6 is provided on the outer wall of the upper slide rail 1, and the strengthening rib 6, the supporting rib 7 and the outer wall of the upper slide rail 1 form a structure with a triangular cross-section. The triangle has better stability and can disperse the downward pulling force received by the side wall of the chute 13 on the outer wall of the upper slide rail 1, avoiding stress concentration, that is, avoiding the fracture of the sliding rib 18 that may be caused by an overweight door panel, and improving the stability of the device during use; further preferably, the strengthening rib 6 and the supporting rib 7 are integrally formed with the upper slide rail 1, with better integrity and stronger stability.

[0030] In this embodiment, the moving component includes a translation block 8 and two pulleys 9. The two pulleys 9 are rotatably arranged coaxially on both sides of the translation block 8, and the axis of the pulley 9 is perpendicular to the length direction of the chute 13. The pulley 9 is in rolling contact with the sliding rib 18, and the pulley 9 is set as a frustum shape. The end with the larger diameter of the pulley 9 is arranged close to the translation block 8. By means of the two frustum-shaped pulleys 9 on both sides, the translation block 8 is always in the middle position between the two sliding ribs 18 during the moving process, avoiding the eccentricity of the moving component during movement, and the practicability is better.

[0031] The length direction of the upper slide rail 1 in this embodiment is set as a straight line, which is suitable for the translation of the hanging rail door;

[0032] In another embodiment, the upper sliding rail 1 can also be set as an arc-shaped track, which is used in cooperation with the hanging rail door panel with the same radian. At this time, the frustum-shaped pulley 9 can also make the translation block 8 move stably, avoiding the possibility of deviating from the track. At the same time, the applicable range of the device is increased, and the practicability is better.

[0033] In this embodiment, the connection component includes a fixing column 10. The fixing column 10 is arranged on the translation block 8. The fixing column 10 is sleeved on the threaded column 14, and the fixing column 10 and the threaded column 14 are in threaded connection. The threaded column 14 is arranged on the connecting fan block 15. The lower part of the connecting fan block 15 is fixedly connected to the upper fan block 2 by screws or bolts. The lower part of the upper fan block 2 is connected to the upper side edge of the door panel. By rotating the threaded column 14, the length of the threaded connection between the fixing column 10 and the threaded column 14 is changed, so as to change the overall length of the connection component, thereby changing the height of the connecting fan block 15, and further changing the height of the hanging rail door panel, which is convenient for the installation of the device and the adjustment after long-term use, and improves the practicability and service life of the device.

[0034] In another embodiment, a safety component is further included, which includes a fixing rail 16 arranged inside the front sliding rail 11 and the rear sliding rail 12 and above the translation block 8. The length direction of the fixing rail 16 is parallel to the length direction of the front sliding rail 11. A clamping block 17 is arranged on the translation block 8. The clamping block 17 is T-shaped. One end of the clamping block 17 far away from the translation block 8 is located inside the fixing rail 16, and in the normal use state, the clamping block 17 has no contact with the inner side of the fixing rail 16 and the inner side of the upper sliding rail 1, so as to avoid the friction between the clamping block 17 and the inner side of the fixing rail 16 and the inner side of the upper sliding rail 1. The side of the fixing rail 16 is used to block the clamping block 17 from moving directly downward. When the moving component falls or detaches, the fixing rail 16 and the clamping block 17 can block the possible falling and toppling of the hanging rail door, further improving the safety of the device during use.

[0035] Working principle: First, the upper sliding rail 1 is prefabricated and can be directly installed at the construction site; the moving component and the connection component are connected, and then the whole composed of the moving component and the connection component is placed at any end of the front sliding rail 11 and the rear sliding rail 12. Preferably, multiple groups can be placed to improve stability; then the upper sliding rail 1 with the moving component and the connection component is installed on the ceiling keel of the door frame; then the threaded column 14 is rotated to adjust the height of the connecting fan block 15 according to the size of the door panel; then the upper fan block 2 is arranged on the connecting fan block 15, and finally the door panel is installed on the connecting fan block 15 to complete the installation of the hanging rail door. When the door panel descends after long-term use, only need to remove the door panel, adjust the relative position of the fixing column 10 and the threaded column 14 and then install the door panel, which prolongs the service life of the device; when the moving component suddenly detaches or the sliding rib 18 breaks, the fixing rail 16 and the clamping block 17 can prevent the whole hanging rail door from falling and toppling, further improving the safety during use.
