After using for a period of time, problems such as misalignment and non-centering are likely to occur between the pulleys on the sliding seat, which further leads to uneven stress on the pulley mechanism, affecting the use effect and service life of the pulley mechanism. Summary of the Invention

[0003] In order to overcome the defects of the above-mentioned existing technology, the present invention provides a pulley mechanism capable of automatically following the track and a door system thereof.

[0004] The technical solution adopted by the present invention to solve its problems is as follows:

[0005] The present invention first provides a pulley mechanism capable of automatically following the track, including a sliding seat arranged in the horizontal frame of the door leaf and a plurality of pulleys arranged on the sliding seat, wherein:

[0006] A pivot member is provided on the sliding seat, and the sliding seat swings left and right in the horizontal plane where the horizontal frame of the door leaf is located through the pivot member.

[0007] In the pulley mechanism of the present invention, when the door leaf slides on the track, the sliding seat can swing left and right in the horizontal plane where the horizontal frame of the door leaf is located through the pivot member, so that the pulleys in the pulley mechanism can automatically adjust their positions along the track, avoiding problems such as misalignment and non-centering between the pulleys. The pulleys are more silent, smoother during use, and have a longer service life.

[0008] Further, the pivot member is a pivot hole for cooperating with a pivot shaft provided on the horizontal frame of the door leaf; or, the pivot member is a pivot shaft for cooperating with a pivot hole provided on the horizontal frame of the door leaf; or, the pivot member is a convex block for cooperating with a groove provided on the horizontal frame of the door leaf; or, the pivot member is a groove for cooperating with a convex block provided on the horizontal frame of the door leaf.

[0009] Further, arc-shaped protrusions for abutting against the horizontal frame of the door leaf are provided on both sides of the sliding seat, and the sliding seat swings left and right in the horizontal plane where the horizontal frame of the door leaf is located with the arc-shaped protrusions as the fulcrum.

[0010] Further, it further includes a locking assembly for arranging the sliding seat in the horizontal frame of the door leaf; the sliding seat and the locking assembly are in sliding fit, so that the sliding seat can swing left and right in the horizontal plane where the horizontal frame of the door leaf is located.

[0011] Further, the locking assembly includes a fixing piece disposed through the sliding seat and a locking member. The fixing piece has a clamping portion for clamping the horizontal frame of the door leaf and a fixing hole; the locking member sequentially passes through the fixing hole and the sliding seat and abuts against the horizontal frame of the door leaf.

[0012] Further, the locking assembly further includes a locking buckle, which is fixedly engaged with the fixing piece in a clamping manner; a through hole for the locking member to pass through is provided on the locking buckle;

[0013] A first clamping groove for the fixing piece to pass through is provided on the sliding seat, and the locking buckle is slidably engaged with the first clamping groove.

[0014] Thus, the locking buckle and the first clamping groove are slidably engaged, so that the sliding seat can swing left and right in the horizontal plane where the horizontal frame of the door leaf is located.

[0015] Further, the locking buckle is a plastic part, and the fixing piece is a metal piece.

[0016] Thus, the locking buckle made of plastic material can reduce the noise generated by the collision between the locking buckle and the fixing piece when the sliding seat swings left and right in the horizontal plane where the horizontal frame of the door leaf is located.

[0017] Further, the locking member is a bolt, and the fixing hole is a threaded hole matching the bolt.

[0018] Further, a cleaning device is further provided on the sliding seat. The cleaning device includes a brush fixing plate fixed in the sliding seat and a brush provided on the brush fixing plate.

[0019] Thus, when the pulley mechanism slides in the horizontal frame of the door leaf, the brush on the sliding seat can clean the horizontal frame of the door leaf to ensure the stability and smoothness of the pulley sliding.

[0020] In addition, a door system of the present invention includes the above pulley mechanism and a door leaf. A horizontal frame of the door leaf is provided at the bottom of the door leaf, and the pulley mechanism is slidably fixed in the horizontal frame of the door leaf.

[0021] In summary, for a pulley mechanism capable of automatically following the track and its door system of the present invention, when the door leaf slides on the track, the sliding seat can swing left and right in the horizontal plane where the horizontal frame of the door leaf is located through the pivoting member, so that the pulley in the pulley mechanism can automatically adjust its position along the track, avoiding problems such as misalignment and non-centering between pulleys. The pulley is more silent, smoother during use, and has a longer service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 1

[0034] Refer to Figures 1-4, the present invention provides a pulley mechanism 1 that can automatically follow the track, including a sliding seat 11 arranged in the horizontal frame 21 of the door leaf, a plurality of pulleys 12 arranged on the sliding seat 11, and a locking assembly 13 arranged at both ends of the sliding seat 11 and used to arrange the sliding seat 11 in the horizontal frame 21 of the door leaf; a pivot member is provided on the sliding seat 11, and the sliding seat 11 swings left and right in the horizontal plane where the horizontal frame 21 of the door leaf is located through the pivot member.

[0035] Specifically, the sliding seat 11 is of a U-shaped structure and includes two vertically arranged side plates 111 and a bottom plate 112 respectively connecting the two side plates 111. The pivot member is a pivot hole 15 arranged on the bottom plate 112 and used to cooperate with a pivot shaft (not shown in the figure) arranged on the horizontal frame 21 of the door leaf. The sliding seat 11 swings left and right in the horizontal plane where the horizontal frame 21 of the door leaf is located through the pivot hole 15. In addition, arc-shaped protrusions 14 used to abut against the side frames of the horizontal frame 21 of the door leaf are provided on the outer side surfaces of the two side plates 111, and the sliding seat 11 swings left and right in the horizontal plane where the horizontal frame 21 of the door leaf is located with the arc-shaped protrusions 14 as the fulcrum.

[0036] It should be noted that the pivot shaft can be a fixed shaft arranged on the horizontal frame 21 of the door leaf, or a fastener such as a bolt or a screw passing through the horizontal frame 21 of the door leaf, and there is no limitation here as long as it satisfies that the pivot hole 15 can rotate around the pivot shaft; the pivot hole 15 is a through hole arranged on the bottom plate 112.

[0037] Of course, in other embodiments, the pivot member can also be a pivot shaft used to cooperate with a pivot hole 15 arranged on the horizontal frame 21 of the door leaf; or, the pivot member can also be a convex block used to cooperate with a groove arranged on the horizontal frame 21 of the door leaf; or, the pivot member is a groove used to cooperate with a convex block arranged on the horizontal frame 21 of the door leaf, and there is no limitation here as long as it satisfies forming a rotation point that allows the sliding seat 11 to swing left and right in the horizontal plane where the horizontal frame 21 of the door leaf is located around the rotation point.

[0038] In this embodiment, the arc-shaped protrusions 14 on the two side plates 111 are symmetrically arranged, and the arc-shaped protrusions 14 are integrally formed with the sliding seat 11.

[0039] Thus, when the door leaf slides on the track, the sliding seat 11 can swing left and right in the horizontal plane where the horizontal frame 21 of the door leaf is located through the pivot hole 15, so that the pulleys 12 in the pulley mechanism 1 can automatically adjust their positions along the track, avoiding problems such as misalignment and non-centering between the pulleys 12. The pulleys 12 are more silent, smoother during use, and have a longer service life.

[0040] Refer to Figures 3-4, further comprising locking components 13 disposed at both ends of the sliding seat 11. The locking components 13 include locking buckles 133, fixing plates 131, and locking members 132. The fixing plate 131 is in the shape of a long strip plate, with clamping portions 1311 at both ends for clamping into the horizontal frame 21 of the door leaf, and a fixing hole 1312 matching the locking member 132 is provided at the center thereof. A first card slot 16 for the fixing plate 131 to pass through is provided on the sliding seat 11. Thus, the locking member 132 passes through the fixing hole 1312 and the sliding seat 11 in sequence and abuts against the bottom frame of the horizontal frame 21 of the door leaf, thereby realizing the setting of the sliding seat 11 within the horizontal frame 21 of the door leaf.

[0041] In this embodiment, the locking member 132 is a bolt, and the fixing hole 1312 is a threaded hole matching the bolt.

[0042] In addition, the locking buckle 133 is in the shape of a rectangular block, with protrusions extending downward at its four corners, and a through hole 1331 for the locking member 132 to pass through is provided at the center thereof. In addition, symmetrical limiting blocks are provided on both sides of the first card slot 16. When the locking buckle 133 is pressed into the first card slot 16 until it abuts against the limiting blocks, the protrusions on the locking buckle 133 abut against the fixing plate 131 at this time, thereby realizing the clamping and fixing of the locking buckle 133 and the fixing plate 131. At the same time, the locking buckle 133 is in sliding fit with the first card slot 16 on the sliding seat 11.

[0043] In this embodiment, the locking buckle 133 is a plastic part, and the fixing plate 131 is a metal sheet.

[0044] Thus, when the door leaf slides on the track, since the locking buckle 133 and the first card slot 16 are in sliding fit, the sliding seat 11 can swing left and right within the horizontal plane where the horizontal frame 21 of the door leaf is located. In addition, the locking buckle 133 made of plastic material can reduce the noise generated by the collision between the locking buckle 133 and the fixing plate 131 when the sliding seat 11 swings left and right within the horizontal frame 21 of the door leaf.

[0045] Refer to Figure 1 , cleaning devices 17 are further provided on both sides of the sliding seat 11. The cleaning devices 17 include brush fixing plates 171 fixed within the sliding seat 11 and brushes 172 provided on the brush fixing plates 171.

[0046] Thus, when the pulley mechanism 1 slides within the horizontal frame 21 of the door leaf, the brush 172 on the sliding seat 11 can clean the horizontal frame 21 of the door leaf to ensure the stability and smoothness of the sliding of the pulley 12.

[0047] Embodiment 2

[0048] Refer to Figures 5-6, this embodiment also provides a door system, including the pulley mechanism 1 in Embodiment 1 and a door leaf. A horizontal frame 21 of the door leaf is provided at the bottom of the door leaf, and the pulley mechanism 1 is slidably fixed within the horizontal frame 21 of the door leaf. A second slot 211 into which a clamping portion 1311 of the fixing piece 131 can extend is provided within the horizontal frame 21 of the door leaf.

[0049] In summary, for a pulley mechanism 1 and its door system capable of automatically following the track according to the present invention, when the door leaf slides on the track, the sliding seat 11 can swing left and right within the horizontal plane where the horizontal frame 21 of the door leaf is located through the pivot hole 15, so that the pulley 12 within the pulley mechanism 1 can automatically adjust its position along the track, avoiding problems such as misalignment and non-centering between the pulleys 12. The pulley 12 is quieter, smoother during use, and has a longer service life.
