[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 16As shown, a suspended door rail system that is easy to adjust in height includes a hanging rail 1 and a hanging rail pulley 31 that slidably cooperates with the hanging rail 1; the hanging rail pulley 31 is transitionally connected to the hanging door 2 through a height adjustment device 5.

[0043] The height adjustment device 5 includes a mounting shell 51 fixedly connected to the hanging door 2, and a vertical slide 511 and a transverse slide 512 which are interconnected are arranged in the mounting shell 51; a horizontal slider 52 is slidably arranged in the transverse slide 512, and a sloped portion 521 is arranged at the bottom of the horizontal slider 52, and a vertical sliding member 53 which slides up and down is arranged in the vertical slide 511; the vertical sliding member 53 includes an inclined plate portion 531 located below the inclined portion 521 and fitted with the inclined portion 521, and vertical plate portions 532 extending upward to the top of the mounting shell 51 are respectively arranged on both sides of the inclined plate portion 531; the vertical plate portion 532 is cooperatively connected with the hanging rail pulley 31; an adjusting bolt 54 is rotatably arranged on one side of the mounting shell 51, and the adjusting bolt 54 extends along the setting direction of the transverse slide 512, and a threaded hole 522 matching the adjusting bolt 54 is arranged on the horizontal slider 52.

[0044] Under the gravity of the hanging door 2, the mounting shell 51 fixed on the hanging door 2 is always subjected to a downward pulling force formed by the gravity of the hanging door 2, and this pulling force also acts on the horizontal slider 52, so the inclined surface 521 at the bottom of the horizontal slider 52 is always in close contact with the inclined plate 531 under the above pulling force. At the same time, due to the limiting effect of the horizontal slide 512 on the horizontal slider 52, the horizontal slider 52 can only move horizontally along the horizontal slide 512; the limiting effect of the vertical slide 511 on the vertical slide 53 can only move vertically along the vertical slide 511. Therefore, by rotating the adjusting bolt 54 to drive the horizontal slider 52 to slide in the horizontal slide 512, when the horizontal slider 52 slides horizontally, the height of the portion of the inclined surface 521 located in the vertical slide 511 forms an adjustment of the upper and lower positions. Since the inclined plate portion 531 is always in close contact with the inclined portion 521, the vertical sliding member 53 is fixed relative to the external reference object. Therefore, when the height of the portion of the inclined portion 521 located in the vertical slideway 511 rises relative to the vertical slideway 511 (such as Fig.17 As shown in part 17-a of the figure, the inclined plate portion 531 and the vertical plate portion 532 rise relative to the vertical slide 511, and the vertical plate portion 532 gradually extends out of the mounting shell 51. The length of the portion of the vertical plate portion 532 extending above the mounting shell 51 becomes longer, and the distance between the hanging door 2 and the hanging rail 1 becomes farther. Finally, the hanging door 2 descends relative to the hanging rail 1, and the adjustment of the hanging door 2 close to the ground is completed. When the height of the portion of the inclined portion 521 located in the vertical slide 511 decreases relative to the vertical slide 511 (as shown in part 17-a of the figure), the inclined plate portion 531 and the vertical plate portion 532 gradually extend out of the mounting shell 51. As the length of the portion of the vertical plate portion 532 extending above the mounting shell 51 becomes longer, the distance between the hanging door 2 and the hanging rail 1 becomes farther. Finally, the hanging door 2 descends relative to the hanging rail 1, and the adjustment of the hanging door 2 close to the ground is completed. Fig.17As shown in part 17-b of the figure), the inclined plate portion 531 and the vertical plate portion 532 descend relative to the vertical slide 511, and the vertical plate portion 532 gradually enters the mounting shell 51. The length of the portion of the vertical plate portion 532 extending above the mounting shell 51 becomes shorter and shorter. Finally, the hanging door 2 rises relative to the hanging rail 1, completing the adjustment of the hanging door 2 away from the ground.

[0045] like Fig.17 As shown, when the hanging door 2 is close to and in contact with the external ground (such as Fig.17 As shown in part 17-a of the figure, when the hanging door 2 is pushed or pulled, friction will be generated with the ground, and the ground will interfere with the hanging door 2, which will increase the movement resistance of the hanging door 2 and make it difficult for the hanging door 2 to move smoothly. At this time, it is necessary to adjust the hanging door 2 away from the ground and make it closer to the hanging rail 1. Therefore, the position of the horizontal slider 52 is adjusted by adjusting the bolt 54 to make the hanging door 2 rise (as shown in part 17-a of the figure). Fig.17 As shown in part 17-b of the figure), when the rising distance of the hanging door 2 is adjusted to H2, the rising distance of the bottom of the hanging door 2 relative to the ground also increases by H2, and finally the hanging door 2 is moved away from the ground to avoid the interference of the ground on the hanging door 2, thereby ensuring the pushing, pulling and opening and closing of the hanging door 2.

[0046] Specifically in this embodiment, Figure 2 and Figure 3 As shown, the hanging rail pulley 31 is arranged on the wheel seat 32 , and the vertical sliding member 53 is connected to the wheel seat 32 through a connecting rod 61 .

[0047] Furthermore, if Figures 8 to 12 , Figures 14 to 16 As shown, the bottom of the wheel seat 32 is provided with a connecting seat 4, and the connecting seat 4 is provided with a evacuation slot 47 which is open on one side. The top of the connecting rod 61 is provided with a hanging block 62 which is used to be suspended above the evacuation slot 47. Specifically, the tops of the two vertical plate portions 532 located on both sides of the inclined plate portion 531 are connected by a transition connecting plate 533, and the connection strength can be strengthened by welding; one side of the connecting rod 61 is connected to the transition connecting plate 533, and the other side of the connecting rod 61 is connected to the hanging block 62. The connecting rod 61 is also preferably connected to the transition connecting plate 533 and the hanging block 62 respectively by welding. When connecting, first fix the connecting seat 4 to the bottom of the wheel seat 32, then insert the connecting rod 61 into the evacuation slot 47 from the open end of the evacuation slot 47, and at the same time, make the hanging block 62 located above the evacuation slot 47, so as to complete the hanging connection between the hanging door 2 and the wheel seat 32.

[0048] Furthermore, if Fig. 9 , Figure 15 to Figure 16As shown, the connecting seat 4 includes a bottom plate 41, and the two sides of the bottom plate 41 are respectively extended upward to form a first extension portion 42 and a second extension portion 44; the tops of the first extension portion 42 and the second extension portion 44 are respectively provided with a first ear plate 43 and a second ear plate 45 extending outward (the side opposite to the first extension portion 42 and the second extension portion 44 is the outer side), and the extension height of the second extension portion 44 is less than the extension height of the first extension portion 42, and the height difference H1 (see Fig.16 ) is greater than the thickness of the hanging block 62, a pad block sleeve 46 is provided on the top of the second ear plate 45, the thickness of the pad block sleeve 46 is the same as the height difference H1, and the avoidance slot 47 is provided on the side facing the second ear plate 45; the first ear plate 43 and the second ear plate 45 are respectively fixedly connected to the wheel seat 32 by bolts, and the second ear plate 45 and both sides of the avoidance slot 47 are fixedly connected to the wheel seat 32 by bolts, two pad block sleeves 46 are used and are respectively provided on both sides of the avoidance slot 47, and the spacing between the two pad block sleeves 46 is greater than the width of the hanging block 62; a limiting portion 48 is provided on the top of the bottom plate 41, and the limiting portion 48 is located between the first ear plate 43 and the second ear plate 45 and is distributed on both sides of the avoidance slot 47, and the length of the hanging block 62 is the same as the spacing between the first extension portion 42 and the second extension portion 44.

[0049] The purpose of this design is: first, the height difference H1 (see Fig.16 ) is greater than the thickness of the hanging block 62, and the spacing between the two cushion block sleeves 46 is greater than the width of the hanging block 62 so that after the connecting seat 4 is fixed on the wheel seat 32, there is enough space above the avoidance notch 47 to allow the hanging block 62 to move from above the second ear plate 45 to above the bottom plate 41. Second, the bottom plate 41, the first extension portion 42, the second extension portion 44 and the limiting portion 48 form a limiting groove, which is used to accommodate and limit the hanging block 62, so that the hanging block 62 is stuck in the above-mentioned limiting groove to prevent the hanging block 62 from moving in the horizontal direction, thereby ensuring the stability when the hanging door 2 is moved.

[0050] Preferably, Fig.12 As shown, the cushion block sleeve 46 is sleeved on the outer side of the connecting bolt corresponding to the second ear plate 45 .

[0051] Specifically in this embodiment, Figures 4 to 7 , Fig.12As shown, the height adjustment device 5 is connected to the hanging door 2 through a fixing plate 55. A receiving groove 21 for receiving the height adjustment device 5 is provided at the top door corner of the hanging door 2, and the receiving groove 21 is open to one side of the top frame and the side frame of the hanging door 2. The fixing plate 55 is configured as an angle plate structure and welded to the mounting shell 51. The two plate arms of the fixing plate 55 are respectively welded to the top of the mounting shell 51 and the side facing the door frame of the hanging door 2, and the two plate arm parts of the fixing plate 55 are fixed to the hanging door 2 by bolts. It should be noted that in this embodiment, the fixing plate 55 part located above the mounting shell 51 is located between the two vertical plate parts 532 and below the transition connecting plate 533 to avoid interference with the up and down sliding of the vertical sliding member 53.

[0052] Preferably, Figure 7 As shown, a connection groove 22 is provided on the hanging door 2 and at the open end of the receiving groove 21. The opening depth of the connection groove 22 is the same as the thickness of the fixing plate 55. The fixing plate 55 is fixed inside the connection groove 22 by bolts. The connection groove 22 is used to accommodate the fixing plate 55. After the fixing plate 55 is installed inside the connection groove 22, the surface of the fixing plate 55 is flush with the side of the hanging door 2, which not only increases the beauty of the installation, but also prevents the fixing plate 55 from affecting the sealing of the hanging door 2 when it is closed.

[0053] In this embodiment, the adjusting bolt 54 is rotatably mounted on the fixing plate 55. Fig. 9 and Fig.13 As shown, the adjusting bolt 54 is a countersunk bolt, and the adjusting bolt 54 passes through the fixing plate 55 and extends to the inside of the transverse slideway 512. A limiting plate 541 is welded to the outside of the adjusting bolt 54, and the limiting plate 541 is close to the inner side of the fixing plate 55. The limiting plate 541 limits the horizontal movement of the adjusting bolt 54, so that the adjusting bolt 54 can only rotate on the limiting plate 541.

[0054] Preferably, the hanging rail 1 is made of an integrally formed high-strength aluminum alloy material without any welding or bolted joints, thereby ensuring the overall structural strength and stability of the rail. The integrally formed design eliminates joints, effectively avoiding stress concentration and improving the overall bearing capacity and service life of the rail.

[0055] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. Although this specification is described in accordance with the implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
