[0048] To make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

[0049] As Figures 1-7 shown, an anti-sway device 100 for a hanging rail sliding door provided by an embodiment of the present invention includes a fixing member 1, a movable member 2, a roller 3, an elastic member 4, and an adjusting member 5. Among them, the fixing member 1 is fixed to the bottom of the hanging rail sliding door to provide an installation basis. The movable member 2 is rotatably installed on the fixing member 1, and a roller 3 is installed on the movable member 2. The elastic member 4 is disposed between the fixing member 1 and the movable member 2 to provide a pre-tightening force, so as to drive the roller 3 to always contact the ground and maintain a constant pressure. The adjusting member 5 is disposed on the fixing member 1 and is connected to the elastic member 4, so as to adjust the magnitude of the pre-tightening force of the elastic member 4, and further adjust the pressure exerted by the roller 3 on the ground (that is: adjust the friction force between the roller 3 and the ground).

[0050] In this embodiment, as Figures 2 to 4 shown, the fixing member 1 is fixed to the inner bottom side of the hanging rail sliding door 200 (refer to Figure 8as shown in the figure), and a receiving cavity 102 with an opening 101 is formed. Specifically, as Figure 3 and Figure 4 shown, the fixing member 1 includes a top plate 11, two side plates 12, a limiting plate 13 and a connecting plate 14. Among them, flange portions 111 are formed on both sides of the top plate 11 for plugging into the door frame 201 of the hanging rail sliding door (as Figure 5 shown). And, a threaded groove 112 is opened at the top of the top plate 11 for installing a bolt 15 to limit the relative position between the top plate 11 and the door frame 201. In addition, a limiting block 113 is provided at one end of the top plate 11 far from the moving member 2 to limit the insertion depth of the top plate 11 into the door frame 201. The two side plates 12 are vertically arranged below the top plate, and the two side plates 12 are parallel to each other. The limiting plate 13 is arranged at the top of the first ends of the two side plates 12 (i.e., Figure 3 the top of the left end of the side plate 12 in the figure) for installing and limiting the adjusting member 5 (detailed description will be given below). The connecting plate 14 is arranged at the bottom of the second ends of the two side plates 12 (i.e., Figure 4 the bottom of the right end of the side plate 12 in the figure), so that an opening 101 is formed between the top plate 11 and the connecting plate 14. Thus, the top plate 11, the two side plates 12, the limiting plate 13 and the connecting plate 14 are used together to enclose a receiving cavity 102 with an opening 101.

[0051] As Figure 6 shown, in this embodiment, the moving member 2 is rotatably installed on the connecting plate 14 of the fixing member 1, and a baffle 21 is formed at one end of the moving member 2 close to the fixing member 1 for abutting against the elastic member 4. And, the roller 3 is rotatably arranged at one end of the moving member 2 far from the fixing member 1 for contacting the ground.

[0052] As Figure 7 shown, in this embodiment, the adjusting member 5 is arranged in the receiving cavity 102 and connected to the elastic member 4 for adjusting the magnitude of the pre-tightening force of the elastic member 4, so as to adjust the magnitude of the pressure exerted by the roller 3 on the ground. Specifically, the adjusting member 5 includes a slider 51 and a threaded rod 52. Among them, the slider 51 is slidably arranged in the receiving cavity 102 to approach or move away from the moving member 2; and, a threaded hole 511 is opened on the slider 51 along the sliding direction. The threaded rod 52 is threadedly connected to the threaded hole 511 of the slider 51 for threadedly cooperating with the slider 51. The elastic member 4 is sleeved on the threaded rod 52, and both ends of the elastic member 4 respectively abut against the slider 51 and the baffle 21. Thus, when the threaded rod 52 is rotated, the slider 51 translates relative to the threaded rod 52 to drive the elastic member 4 to expand and contract, so as to adjust the pre-tightening force of the elastic member 4. And, during the translation of the slider 51, the elastic member 4 exerts an elastic pressure on the slider 51 to drive one end of the threaded rod 52 far from the moving member 2 to always abut against the limiting plate 13.

[0053] In addition, preferably, in this embodiment, bumps 121 are provided on the inner walls of both side plates 12. The bumps 121 and the inner wall of the accommodating cavity 102 cooperate to form a rectangular slideway. The slider 51 is a rectangular slider, and the rectangular slider is slidably matched with the rectangular slideway to guide the sliding of the slider 51.

[0054] In the above embodiment, preferably, as Figure 4 shown, a connection hole 141 is formed in the connection plate 14, and a serrated shaft 6 is inserted through the connection hole 141. The movable member 2 is connected to the serrated shaft 6 so that the movable member 2 can rotate relative to the connection plate 14 about the axis of the serrated shaft 6. It can be understood that since a plurality of serrations are evenly distributed in the circumferential direction of the serrated shaft 6, the friction between the serrated shaft 6 and the inner surface of the connection hole 141 can be increased, so as to prevent the movable member 2 from swinging greatly under the action of an external force, which is beneficial to improving the stability of the structure.

[0055] In the above embodiment, preferably, the fixing member 1 is integrally formed. In other embodiments, the fixing member 1 can also be made into a split structure according to needs, which is not specifically limited herein.

[0056] As Figure 8 shown, an embodiment of the present invention further provides a suspended rail sliding door, and the suspended rail sliding door includes the above anti-swing device.

[0057] In summary, an anti-swing device and a suspended rail sliding door for a suspended rail sliding door provided by an embodiment of the present invention have the following beneficial effects:

[0058] (1) By providing a pre-tightening force through the elastic member, friction is generated between the pulley 5 and the ground, thereby reducing the swing of the door leaf during the pushing and pulling process and improving the stability of the use of the door leaf.

[0059] (2) The adjusting member is composed of the slider 51 and the threaded rod 52 to adjust the magnitude of the pre-tightening force of the elastic member, and further adjust the magnitude of the friction force between the pulley 5 and the ground to adapt to different installation conditions.

[0060] (3) A rectangular slideway is formed on the fixing member 1 to slidably cooperate with the rectangular slider 51, thereby guiding the sliding of the slider 51; and. The top plate 11 of the fixing member 1 can be stably inserted into the door frame of the suspended rail sliding door, ensuring the stability of the installation.
