In the description of this application, unless otherwise expressly defined, terms such as "set," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0028] The following is combined Figures 1 to 8 The embodiments of this application are described below.

[0029] Based on the above, this application provides a traction device, which includes a connecting seat 100, a belt clamp 200, and a fastener 300. The connecting seat 100 has a limiting groove 110 at its top. One end of the belt clamp 200 has a connecting rod 210, and the other end has a traction member 220. The connecting rod 210 and the traction member 220 are connected, and the connecting rod 210 is inserted into the limiting groove 110. The connecting seat 100 has a fastening hole 120, and the fastener 300 is engaged with the fastening hole 120 to fix the connecting rod 210 to the limiting groove 110.

[0030] During installation, first align the end of the belt clip 200 with the connecting rod 210 with the limiting groove 110 on the top of the connecting seat 100, and slowly insert it so that the connecting rod 210 falls into the limiting groove 110. Then, select a suitable fastener 300, align its screw 320 with the fastening hole 120 on the connecting seat 100, and begin tightening. Continue tightening until the fastener 300 secures the connecting rod 210 to the limiting groove 110.

[0031] Therefore, the belt clip 200 is directly inserted into the limiting groove 110 at the top of the connecting seat 100 via the connecting rod 210. It can be fixed simply by engaging the fastener 300 with the fastening hole 120 of the connecting seat 100. This allows for convenient and quick replacement of the corresponding parts. At the same time, belt clips 200 of different specifications can be quickly replaced according to different usage scenarios.

[0032] Reference Figure 3 And refer to Figure 5 In some embodiments, the fastener 300 includes a nut 310, a screw 320, and an inclined portion 330. The screw 320 is connected to the fastening hole 120. The nut 310 and the screw 320 are connected through the inclined portion 330. The inclined portion 330 is gradually widened towards the nut 310, and both sides of the inclined portion 330 are gradually inclined outwards towards the nut 310. Optionally, the outer circumferential surface of the screw 320 is provided with an external thread, and the fastening hole 120 is provided with an internal thread, with the external thread and the internal thread engaging for connection.

[0033] During fixing, align one end of the screw 320 with the fastening hole 120 of the connecting seat 100 and screw the screw 320 in, so that the screw 320 engages with the internal thread of the fastening hole 120. Simultaneously, as the fastener 300 continues to rotate, the screw 320 continuously advances within the fastening hole 120. Since the inclined portion 330 is gradually widened towards the nut 310, during the screwing process, the inclined portion 330 contacts the connecting rod 210, and as it continues to screw in, it further presses the connecting rod 210, thereby fixing the connecting rod 210 within the limiting groove 110 and enhancing the fastening effect. Furthermore, by providing the inclined portion 330 on the fastener 300, a single traction structure can be used with multiple belt clip specifications, meaning that one connecting seat 100 can accommodate belt clips of various sizes.

[0034] Next refer to Figure 2 In some embodiments, the connector 100 is provided with a fixing hole 130, and a limiting step 140 for riveting is provided in the fixing hole 130. During installation, the connector 100 is placed at the corresponding position of the push-pull assembly, so that the fixing hole 130 on the connector 100 is aligned with the corresponding riveting position on the push-pull assembly. Then, a rivet corresponding to the limiting step 140 is selected and inserted into the fixing hole 130. Then, a riveting tool is used to rivet the rivet to further enhance the stability of the connector 100 after installation.

[0035] In some embodiments, the outer side of the traction member 220 is provided with a plurality of traction holes 221 for connection with the belt 500. One end of the belt 500 is aligned with the traction hole 221 and passed through the opposing traction hole 221 to achieve connection between the belt 500 and the traction device by means of the traction hole 221.

[0036] Furthermore, bolts or other suitable connectors can also be used to limit the movement of belt 500, for example, see reference. Figure 7 The diagram shows a connection method between a belt 500 and a connector. The traction device also includes a pin 400. The top of the traction member 220 is provided with a plug hole 222, which is connected to the traction hole 221. The pin 400 is used to at least partially extend into the plug hole 222 to limit the belt 500. In other words, after installing the belt 500 into the traction hole 221, select a pin 400 that matches the insertion hole 222, align one end of the pin 400 with the insertion hole 222 on the top of the traction member 220, so that the pin 400 is at least partially inserted into the insertion hole 222. Since the insertion hole 222 is connected to the traction hole 221, the insertion of the pin 400 will prevent the belt 500 from moving in the traction hole 221, preventing the belt 500 from falling off, and ensuring a stable connection between the belt 500 and the traction member 220 of the traction device. Alternatively, an external thread can be provided on the outside of the pin 400, and a corresponding internal thread can be provided in the insertion hole 222 to tighten and fix the pin 400 on the traction member 220, ensuring the stability of the belt 500 after installation.

[0037] In some embodiments, the top of the connecting seat 100 is provided with a folded edge 150, and a protrusion 160 is provided on the folded edge 150. The connecting seat 100, the folded edge 150, and the protrusion 160 surround to form a limiting groove 110. When installing the belt clip 200, align the connecting rod 210 of the belt clip 200 with the limiting groove 110, and insert the connecting rod 210 into the limiting groove 110 along the guide of the limiting groove 110. Then, use the fastener 300 to fix the connecting rod 210. During the tightening of the fastener 300, the connecting rod 210 is gradually fixed in the limiting groove 110, thereby ensuring that it will not loosen or shift.

[0038] In some embodiments, the connecting rod 210 is connected to the traction member 220 via a connecting portion 230, which is arc-shaped. The flexibility of the arc-shaped structure allows the traction member 220 to twist or change angle within a certain range. In other words, through the arc-shaped connecting portion 230, the traction member 220 can rotate along the connecting rod 210 at a certain angle, allowing it to flexibly adjust its angle and better adapt to the movement of the belt 500. Furthermore, when connected to the mounting rail, the arc-shaped or "U"-shaped connecting portion prevents interference with the edges of the rail or window frame profile, thus ensuring stable operation of the belt clamp 200 and its adaptability to different working conditions.

[0039] In some embodiments, the connector 100 is further provided with a connection hole 170 for connecting with other accessories such as adjusting bolts, and the connection hole 170 is located below the fastening hole 120. For example, after the connector 100 is fixed, adjusting bolts can be inserted into the connection hole 170, and it is not necessary to provide additional connectors on the connector 100 to easily connect or fix it with other components.

[0040] This application also provides a linked sliding door, which includes the traction device described above. (See reference...) Figure 8 In actual assembly, after the transmission wheel seat and the anti-jump upper wheel are installed in the track groove, the transmission wheel seat and the anti-jump upper wheel seat can be connected by a traction device. The connection and adjustment are convenient, which not only improves the convenience of operation, but also enhances the overall aesthetics and practicality.
