[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] This utility model provides, for example Figure 1-4 The single guide wheel chain shown includes multiple connecting chain pieces 1, each consisting of a first chain piece 2 and a second chain piece 3. Adjacent connecting chain pieces 1 are connected by an intermediate section 4. A circular hole 5 is provided between the first chain piece 2 and the second chain piece 3. A pulley 6 is provided between the first chain piece 2 and the second chain piece 3. Fixed shafts 7 are installed at both ends of the pulley 6. A telescopic rod 8 is installed on the fixed shaft 7, with one end of the telescopic rod 8 extending into the circular hole 5.

[0023] The installation process of this single guide wheel chain is as follows: connect multiple connecting chain pieces 1 through intermediate sections 4, shorten the telescopic rod 8 on the pulley 6 so that the telescopic rod 8 moves between the first chain piece 2 and the second chain piece 3, and when the telescopic rod 8 moves to the round hole 5, extend the telescopic rod 8 so that the pulley 6 can be installed on the connecting chain piece 1.

[0024] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 4 The fixed shaft 7 has a square groove 9. The telescopic rod 8 includes a square rod 10 located in the square groove 9. One side surface of the square rod 10 and the inner side surface of the square groove 9 are connected by a telescopic spring 11. A round rod 12 is installed at one end of the square rod 10. A universal ball bearing 13 is installed at one end of the round rod 12. The round rod 12 can extend into the round hole 5.

[0025] The telescopic rod 8 extends and retracts as follows: A square groove 9 is provided on the fixed shaft 7. When the telescopic rod 8 is shortened, the square rod 10 can be moved into the square groove 9, thereby reducing the size of the entire guide wheel. When the square rod 10 moves into the square groove 9, the telescopic spring 11 can be compressed. When the round rod 12 moves to the round hole 5, the square rod 10 is released. Under the elastic force of the telescopic spring 11, the telescopic rod 12 can be pushed outward, thereby allowing the guide wheel to be installed. The universal ball bearing 13 can reduce the friction during the installation of the guide wheel.

[0026] Refer to the instruction manual appendix Figure 3Included with instruction manual Figure 4 A baffle 14 is installed at the end of the circular rod 12 away from the universal ball bearing 13. The baffle 14 can press against the inside of the connecting chain 1 to facilitate the positioning of the guide wheel.

[0027] Refer to the instruction manual appendix Figure 1 An extension plate 15 is installed between the first chain link 2 and the second chain link 3. The extension plate 15 can increase the width of the first chain link 2 and the second chain link 3, thereby increasing the tensile strength.

[0028] This utility model provides, for example Figure 5-7 The single guide wheel chain installation fixture shown includes a workbench 16, with U-shaped limit blocks 17 installed on both sides of the upper end of the workbench 16, and the two ends of the extension plate 15 pressing against the inner side of the U-shaped limit blocks 17. A guide frame 18 is installed on the upper end of the U-shaped limit blocks 17, and the guide frame 18 can guide the telescopic rod 8.

[0029] The installation process of the single guide wheel chain is as follows: The worker clamps the extension plate 15 into the U-shaped limit block 17, which makes it easier to position the connecting chain piece 1. Then, the telescopic rod 8 is placed into the guide frame 18. As the guide wheel is pushed downward, the telescopic rod 8 can be gradually compressed, which makes it easier to install the guide wheel.

[0030] Refer to the instruction manual appendix Figure 5 Instruction manual attached Figure 6 Included with instruction manual Figure 7 The guide frame 18 includes two limiting slides 19 located above the U-shaped limiting block 17. The limiting slides 19 are connected to the upper end of the U-shaped limiting block 17 via connecting rods 20. An inclined slide 21 is installed on the upper end of the limiting slides 19.

[0031] The process of the guide frame 18 guiding the telescopic rod 8 is as follows: the universal ball bearings 13 and the round rod 12 at both ends of the telescopic rod 8 are placed into the inclined slide 21. When the guide wheel is pushed downward, the round rod 12 can be pushed to one side under the action of the inclined surface of the inclined slide 21, which makes it easier to compress the telescopic rod 8. Then it can enter the inner side of the connecting chain plate 1 through the limiting slide 19.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
