[0037] In the description of the present application, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present application in combination with the specific content of the technical solution.

[0038] The following will be combined with Figures 1 to 14 to make a detailed description of the embodiments of the present application.

[0039] First, refer to Figures 1 to 3 , the present application provides a linkage sliding device, which includes a first guide rail 100, an anti-jump upper wheel set 200, a second guide rail 300, a transmission wheel seat 400 and a traction component 500. The first guide rail 100 has a first guide groove 2411; the anti-jump upper wheel set 200 is arranged on the first guide groove 2411; the second guide rail 300 has a second guide groove 2321; the transmission wheel seat 400 is arranged on the second guide groove 2321, and a belt (not shown in the figure) is sleeved on the transmission wheel seat 400;

[0040] Then, refer to Figures 4 to 6The shown traction assembly 500 includes a connecting seat 510, a belt clip 520 and a fixing member 220. The connecting seat 510 is fixed to the anti-jump upper wheel. One end of the belt clip 520 has a connecting rod 521, and the other end has a traction member 522. A traction hole 5221 is provided on the traction member 522, and the belt is connected to the traction hole 5221. A fastening hole 511 and a limiting groove 512 are provided on the connecting seat 510. The connecting rod 521 is inserted into the limiting groove 512, and a fastener 530 is connected with the fastening hole 511 in a matching manner to fix the connecting rod 521 on the limiting groove 512.

[0041] During installation, first, align the end of the belt clip 520 with the connecting rod 521 with the limiting groove 512 at the top of the connecting seat 510, and slowly insert it so that the connecting rod 521 falls into the limiting groove 512. Subsequently, select a suitable fastener 530, align its screw rod 532 with the fastening hole 511 on the connecting seat 510, and start screwing. Until the fastener 530 fixes the connecting rod 521 on the limiting groove 512. A plurality of traction holes 5221 for connecting with the belt are provided on the outer side of the traction member 522. Align one end of the belt on the transmission wheel seat 400 with the traction hole 5221 and pass through the relatively arranged traction holes 5221, so as to realize the connection between the belt and the traction assembly 500 by means of the traction hole 5221, thereby connecting the transmission wheel seat 400 and the anti-jump upper wheel set 200 through the traction assembly 500.

[0042] Thus, by providing the traction assembly 500, the belt clip 520 is directly inserted into the limiting groove 512 at the top of the connecting seat 510 through the connecting rod 521. Only by matching the fastener 530 with the fastening hole 511 of the connecting seat 510 can the connection and fixation of the linkage sliding device be completed, and the corresponding components can be replaced conveniently and quickly. At the same time, different specifications of belt clips 520 can be quickly replaced according to different usage scenarios.

[0043] Specifically, continue to refer to Figure 6 The fastener 530 includes a nut 531, a screw rod 532 and an inclined portion 533. The screw rod 532 is connected with the fastening hole 511. The nut 531 and the screw rod 532 are connected through the inclined portion 533, and the inclined portion 533 is arranged to gradually expand towards the direction of the nut 531. Optionally, an external thread is provided on the outer peripheral surface of the screw rod 532, and an internal thread is provided in the fastening hole 511, and the external thread is connected with the internal thread in a matching manner.

[0044] When fixing, align one end of the screw rod 532 with the fastening hole 511 of the connecting seat 510, and screw the screw rod 532 in. The screw rod 532 meshes with the internal thread of the fastening hole 511. At the same time, as the fastener 530 continues to rotate, the screw rod 532 continuously advances in the fastening hole 511. Since the inclined portion 533 is arranged to gradually expand towards the direction of the nut 531, during the advancing process, the inclined portion 533 contacts the connecting rod 521, and continues to advance to further press the connecting rod 521, thereby fixing the connecting rod 521 in the limiting groove 512 and strengthening the fastening effect. Additionally, by providing the inclined portion 533, a traction structure can also be made to be applicable to multiple specifications of the belt clip 520, that is, it can be adapted to belt clips 520 of various different sizes.

[0045] The connecting seat 510 is provided with a fixing hole 211, and a limiting step for riveting and fixing is provided in the fixing hole 211. During installation, place the connecting seat 510 at the corresponding groove position of the anti-jump upper wheel set 200, align the fixing hole 211 on the connecting seat 510 with the corresponding riveting position on the push-pull assembly, then select a rivet corresponding to the limiting step, insert it into the fixing hole 211, and then use a riveting tool to perform a riveting operation on the rivet to further enhance the stability of the connecting seat 510 after installation.

[0046] The top of the connecting seat 510 is provided with a folding edge 513, and a first convex block 514 is provided on the folding edge 513. The connecting seat 510, the folding edge 513 and the first convex block 514 enclose to form a limiting groove 512. When installing the belt clip 520, align the connecting rod 521 of the belt clip 520 with the limiting groove 512, and insert the connecting rod 521 into the limiting groove 512 along the guidance of the limiting groove 512. Subsequently, use the fastener 530 to fix the connecting rod 521. During the process of tightening the fastener 530, the connecting rod 521 is gradually fixed in the limiting groove 512, thereby ensuring that it will not loosen or shift.

[0047] The connecting rod 521 is connected to the traction member 522 through a connecting portion 523, and the connecting portion 523 is arc-shaped. Utilizing the flexibility of the arc-shaped structure, the traction member 522 can be twisted or changed in angle within a certain range. That is to say, through the arc-shaped connecting portion 523, the traction member 522 can rotate at a certain angle along the connecting rod 521, enabling the traction member 522 to flexibly adjust the angle and better adapt to the movement of the belt. Additionally, when connecting to the installation rail, by providing an arc-shaped or "U"-shaped connecting portion 523, interference with the edge of the rail or window frame profile can also be avoided, thereby ensuring the stable operation of the belt clip 520 and enabling it to adapt to different working states.

[0048] The connecting seat 510 is further provided with connecting holes for connecting with other accessories such as adjusting bolts, and the connecting holes are arranged below the fastening holes 511. Exemplarily, after the connecting seat 510 is fixed, other adjusting bolts can be inserted into the connecting holes, so that it is convenient to connect or fix with other components without additionally connecting external connectors on the connecting seat 510.

[0049] Continue to refer to Figure 5 In some embodiments, the traction assembly 500 further includes a pin 540. A plug hole 5222 is provided at the top of the traction member 522, and the plug hole 5222 communicates with the traction hole 5221. The pin 540 is used to at least partially extend into the plug hole 5222 to limit the belt. That is, after the belt is installed into the traction hole 5221, a pin 540 adapted to the plug hole 5222 is selected, one end of the pin 540 is aligned with the plug hole 5222 at the top of the traction member 522, and the pin 540 at least partially extends into the plug hole 5222. Since the plug hole 5222 communicates with the traction hole 5221, the inserted pin 540 will block the movement of the belt in the traction hole 5221, prevent the belt from falling off, and ensure the stable connection between the belt and the traction member 522 of the traction device. Additionally, external threads can be provided on the outside of the pin 540, and corresponding internal threads are provided in the plug hole 5222, so that the pin 540 can be tightened and fixed on the traction member 522 to ensure the stability after the belt is installed.

[0050] Then refer to Figures 7 to 10 In some embodiments, the anti-jump upper wheel set 200 includes a wheel body 210, a fixing member 220, an anti-jump assembly 230 and an anti-sway assembly 240. The anti-jump assembly 230 and the anti-sway assembly 240 are both arranged on the wheel body 210. A fixing hole 211 is further provided on the wheel body 210, and the fixing member 220 is threadedly connected to the fixing hole 211. A tapered spike portion 221 is provided at the bottom end of the fixing member 220. By providing the anti-sway assembly 240, the anti-jump upper wheel is prevented from swaying left and right in the slide rail. By providing the anti-jump assembly 230, one end of the entire anti-jump upper wheel is prevented from tilting when the sliding door is pushed and pulled; during actual assembly, by providing the spike portion 221, the fixing member 220 is screwed downwards so that the spike portion 221 contacts the slide rail, causing deformation on the contact surface to further fix the entire anti-jump upper wheel. Additionally, the spike portion may not be provided, and a bottom plate may be provided at the bottom of the fixing member. The bottom plate is connected to the bottom of the fixing member, and the bottom plate is pressed against the guide rail by screwing the fixing member.

[0051] In some embodiments, the anti-sway assembly 240 includes a first moving plate 241, a first moving piece, a first guide wheel 243, and a hollow cylinder 244. The first moving plate 241 is disposed on the wheel body 210, the first moving piece is disposed on the first moving plate 241. The first moving plate 241 is slidably connected to the wheel body 210, and the first movable piece 242 is rotatably connected to the first moving plate 241. There are two first guide wheels 243, and the two first guide wheels 243 are disposed at both ends of the first moving piece. A first guide post 2421 is disposed below the first moving piece, and a first guide groove 2411 is formed on the first moving plate 241. The first guide post 2421 is inserted into the first guide groove 2411. That is, when the first moving plate 241 is moved along the length direction of the wheel body 210, it drives the guide piece to rotate left and right. The hollow cylinder 244 sequentially passes through the guide wheel group and the first moving plate 241 and is connected to the fixing hole 211 on the wheel body 210. Furthermore, by providing the anti-sway assembly 240, the first guide wheel 243 is prevented from swaying left and right in the guide rail.

[0052] In some embodiments, the anti-jump assembly 230 includes a jump-stop wheel 231, a movable plate 232, and a jump-stop piece 233. The movable plate 232 is rotatably connected to the wheel body 210 and the jump-stop piece 233 respectively. The jump-stop wheel 231 is disposed on the jump-stop piece 233. A second guide groove 2321 is formed on the movable plate 232, and a second guide post 2331 is formed on the jump-stop piece 233. The second guide post 2331 is inserted into the second guide groove 2321. A third guide groove 213 is formed on the wheel body 210, and a second convex block 2323 corresponding to the third guide groove 213 is formed on the movable plate 232. The second convex block 2323 is inserted into the third guide groove 213.

[0053] The wheel body 210 is provided with a rotation connection hole 212. The connection column 2332 on the jump-stop piece 233 sequentially passes through the fourth guide groove 2322 and the rotation connection hole 212. The movable plate 232 is disposed between the jump-stop piece 233 and the wheel body 210, so that the movable plate 232 can be rotatably connected to the wheel body 210 and the jump-stop piece 233 respectively. The second convex block 2323 is movably connected to the third guide groove 213, that is, the convex block can slide in the guide groove, and the third guide groove 213 is horizontally disposed, so as to limit the lateral movement distance of the jump-stop piece 233, so as to better adjust the position of the jump-stop wheel 231 and further prevent the wheel body 210 from jumping.

[0054] When the sliding door moves, the wheel body 210 may be subjected to an upward force and tend to jump. At this time, the jump-stop wheel 231 contacts the slide rail, and the jump-stop piece 233 slides in the second guide groove 2321 through the second guide post 2331, so that the position of the jump-stop wheel 231 can be adjusted according to the movement condition of the wheel body 210 to offset the upward force, thereby effectively preventing the wheel body 210 from jumping upward and improving the stability of the anti-jump upper wheel during the movement of the sliding door.

[0055] Inside the wheel body 210, there are also a first adjusting bolt 250 and a second adjusting bolt 260. The first adjusting bolt 250 is threadedly connected to the moving plate. By screwing the first adjusting bolt 250, the first moving plate 241 can be driven to move back and forth along the length direction of the first adjusting bolt 250, thereby driving the first movable piece 242 to rotate; the second adjusting bolt 260 is threadedly connected to the movable plate 232. When the position of the movable plate 232 needs to be adjusted, the second adjusting bolt 260 is screwed. Since the movable plate 232 is threadedly connected to the second adjusting bolt 260, the movable plate 232 will move axially along with the rotation of the bolt, and then the anti-jump piece 233 drives the anti-jump wheel 231 to move to a suitable position.

[0056] Next, referring to Figures 11 to 14 , in some embodiments, the drive wheel seat 400 includes a seat body 410, a drive assembly 420, a guide assembly 430, a third adjusting bolt 440, and a fourth adjusting bolt 450. One end of the seat body 410 is provided with a drive assembly 420 for belt drive connection, and the other end of the seat body 410 is provided with a guide assembly 430 for preventing left and right offset. The third adjusting bolt 440 is connected to the drive assembly 420, and the fourth adjusting bolt 450 is connected to the guide assembly 430 to respectively adjust the positions of the drive assembly 420 and the guide assembly 430.

[0057] Specifically, the drive assembly 420 includes two drive wheels 421 and a sliding plate 422. The two drive wheels 421 are arranged side by side along the width direction of the seat body 410. The sliding plate 422 is arranged on the seat body 410, and the sliding plate 422 is slidably connected to the seat body 410. The two drive wheels 421 are arranged on the sliding plate 422. The sliding plate 422 can move along the length direction of the seat body 410. When the belt tension needs to be adjusted, or when the relative position between the drive wheel 421 and other components needs to be changed, the sliding plate 422 is driven to move along the length direction of the seat body 410 by screwing the adjusting bolt. After adjusting to the appropriate position, the sliding plate 422 is fixed. By flexibly adjusting the position of the sliding plate 422 to drive the drive wheel 421 to move synchronously, the position of the drive wheel 421 is adjusted to adjust the belt tension or the connection position with other components to ensure the stability of the belt drive.

[0058] When it is necessary to adjust the position of the transmission wheel 421, turn the third adjusting bolt 440. Since the bolt is threadedly connected to the sliding plate 422, the rotation of the bolt will be converted into the linear movement of the sliding plate 422 along the length direction of the seat body 410. That is, by changing the turning direction, the sliding plate 422 will move back and forth along the length direction of the seat body 410. After reaching the required position, stop turning to fix the sliding plate 422, thereby realizing the adjustment of the position of the transmission wheel 421 along the length direction of the seat body 410. Therefore, by turning the adjusting bolt to move the sliding plate 422 back and forth along the length direction of the seat body 410 for position adjustment, the operation is convenient and the adjustment efficiency is improved.

[0059] Furthermore, in order to more conveniently adjust the distance between the two transmission wheels 421, an activity block 423 and a fixing bolt 424 are also provided on the movable plate 232. The transmission wheel 421 is arranged on the activity block 423. A kidney-shaped hole 4231 is provided on the activity block 423. One end of the fixing bolt 424 passes through the kidney-shaped hole 4231 and is fixedly connected to the movable plate 232. It can be understood that the kidney-shaped hole 4231 is a hole shape with two parallel sides and two arc sides.

[0060] During actual assembly, two activity blocks 423 are provided. A transmission wheel 421 is fixedly arranged on each activity block 423. After fixing the activity block 423 on the movable plate 232 with the fixing bolt 424, the two transmission wheels 421 are at the initial distance. Loosen the fixing bolt 424 so that the activity block 423 can move within the range of the kidney-shaped hole 4231. Since the transmission wheel 421 is arranged on the activity block 423, moving the activity block 423 will drive the transmission wheel 421 to move together, thereby changing the distance between the two transmission wheels 421.

[0061] When it is necessary to increase the distance between the transmission wheels 421, move the two or one of the activity blocks 423 outward; conversely, move the activity block 423 inward. When the distance between the transmission wheels 421 is adjusted to the appropriate position, tighten the corresponding fixing bolt 424 on the activity block 423 to fix the activity block 423 on the sliding plate 422 again. The structure is simple, the adjustment is convenient, the versatility of the transmission assembly 420 is improved, and it can be flexibly adjusted to adapt to the size specifications of other fitting parts.

[0062] Furthermore, during the belt drive process, the belt generates a dragging force on the driving wheel 421, which easily causes the driving wheel 421 to warp and deform, resulting in poor contact between the belt and the driving wheel 421 and accelerating wear. Therefore, in some embodiments, a pressing plate 425 is further provided on the sliding plate 422. One end of the pressing plate 425 is fixed to the movable block 423, and the other end of the pressing plate 425 abuts against the top of the driving wheel 421. Thus, by providing the pressing plate 425, the warping tendency of the driving wheel 421 caused by the dragging force is inhibited. That is to say, the pressing plate 425 can limit the movement of the driving wheel 421, prevent the driving wheel 421 from warping and deforming due to the belt dragging force, extend the service life of the driving wheel 421 and the belt, and further improve the stability of the transmission system.

[0063] In addition, plug heads or end caps usually need to be installed at both ends of the seat body 410 to enhance the structural stability, that is, additional components for closing the end openings need to be provided for assembly, which is inconvenient to use. Therefore, in some embodiments, downward folding portions 411 are respectively provided at both ends of the seat body 410, and the outer end surfaces of each folding portion 411 are flush with the end surfaces of the seat body 410. In this way, there is no need to provide additional plug heads at both ends of the seat body 410.

[0064] Therefore, the folding portions 411 increase the structural stability of the ends of the seat body 410, prevent the frame from gradually deforming under the belt dragging force during the drive process, and improve the stability of the entire driving wheel seat 400. Therefore, the folding portions 411 at both ends of the seat body 410 play the role of replacing the plug heads, not only improving the bending resistance and deformation resistance of the ends of the seat body 410, but also simplifying the structure of the entire seat body 410.

[0065] Further, connection holes are provided on the folding portions 411, and there are two connection holes, which are respectively used to connect with the third adjusting bolt 440 or the fourth adjusting bolt 450. During the installation and adjustment process, the third adjusting bolt 440 or the fourth adjusting bolt 450 is connected to the folding portion 411 through the connection hole, so that the position adjustment of the components on the driving wheel seat 400 can be conveniently realized from the outside of the wheel body. Therefore, the stability of the driving wheel seat 400 is improved, the internal structure is simplified, and the convenience of installation and maintenance is improved.

[0066] In some embodiments, the guiding assembly 430 includes a second moving plate 431 and a second movable piece 432. The second moving plate 431 is disposed on the base body 410 and is slidably connected to the base body 410. The second movable piece 432 is disposed above the second moving plate 431 and is slidably connected to the second moving plate 431. Second guiding wheels 433 are provided at both ends of the second moving plate 431. A fifth guiding groove 4311 is provided on the second moving plate 431. A third guiding post is provided at the bottom of the second movable piece 432, and the third guiding post is connected in cooperation with the fifth guiding groove 4311. The third guiding post is inserted into the fifth guiding groove 4311. In actual setting, there are two fifth guiding grooves 4311, and there are two corresponding third guiding posts, and the positions of the third guiding posts correspond to those of the fifth guiding grooves 4311.

[0067] Similarly, when it is necessary to adjust the position of the second guiding wheel, by screwing the fourth adjusting bolt 450, the movable piece is moved along the length direction of the base body 410. The third guiding post at the bottom of the second movable piece 432 slides in the guiding groove of the second moving plate 431 to form a movable connection, thereby driving the second moving plate 431 to rotate or move, guiding the second moving plate 431 to move in a predetermined direction, and further realizing the adjustment of the position of the second guiding wheel.
