[0019] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0020] according to Figure 1-7 As shown, a tension link for textile machinery includes a connector 1 with a notch on its surface and outwardly extending fastening protrusions 2 on both sides of the notch. The two fastening protrusions 2 are connected by bolts. The connector 1 has a lubricating oil cavity 3 inside, which communicates with the inner side of the connector 1 through a through hole 4. The two connectors 1 are connected by an assembly assembly, which includes two assembly rods 5 connected to the two connectors 1. The two ends of the assembly rods 5 are respectively provided with a first threaded portion 6 and a second threaded portion 7. The first threaded portion 6 is threadedly connected to the connector 1, and the second threaded portion 7 is connected to an adjustment assembly.

[0021] In the above specific technical solution, in order to reduce the wear of the tension connecting rod on the connecting head 1 during operation, a lubrication oil cavity 3 is provided on the connecting head 1. The operator injects lubricating oil into the lubrication oil cavity 3, and the lubricating oil flows through the through hole 4 to the connection between the connecting shaft and the connecting head 1 to lubricate it.

[0022] Meanwhile, to increase the ease of installation of the tension link, the tension link adopts an assembly type. First, the two heads of the tension link are connected to the first threaded part 6 of the two assembly rods 5, and the second threaded part 7 of the two assembly rods 5 are connected to the adjustment component respectively. If the length of the tension link is not suitable, the length can be adjusted by the adjustment component.

[0023] After the tension link is installed, tightening the bolts on the fastening protrusion 2 can improve the firmness of the connection between the tension link and the connecting shaft and reduce the noise generated by vibration during the operation of the tension link.

[0024] The adjustment assembly includes an adjustment rod 8, with rotating plates 9 at both ends of the adjustment rod 8. Several rotating plates 9 are circumferentially distributed around the central axis of the adjustment rod 8. Each rotating plate 9 has a thread that mates with the second threaded part 7. The rotating plates 9 are rotatably mounted on the inner wall of the adjustment rod 8 near the end of the adjustment rod 8 via a fixing seat 10. The other end of the rotating plate 9 is connected to the inner wall of the adjustment rod 8 via a spring 11. When the second threaded part is not inserted into the adjustment rod 8, the rotating plate 9 is tilted towards the center of the adjustment rod 8 under the action of the spring 11. When the second threaded part is inserted into the adjustment rod 8, the rotating plate 9 changes from an tilted state to a vertical state.

[0025] The middle part of the adjusting rod 8 is provided with two threaded fixing parts 12 with opposite directions of rotation. The two threaded fixing parts 12 respectively cooperate with the second threaded parts 7 on the mounting rods 5 on both sides. The threaded fixing parts 12 at both ends are separated by the partition protrusion 13.

[0026] In the above specific technical solution, when it is necessary to adjust the length of the tension link by adjusting the components, first assemble the tension link, hold the assembly rods 5 at both ends, and then rotate the adjusting rod. By rotating, the adjusting rods at both ends move to the middle or both sides at the same time, thereby adapting to the installation length.

[0027] Specifically, the assembly process of the tension link is as follows: First, the connector 1 is connected to the assembly rod 5. Then, the second threaded part 7 of the assembly rod 5 is inserted into the adjusting rod 8. During the insertion of the second threaded part 7, the rotating plate 9 changes from an inclined state to a vertical state, so that the thread on the rotating plate 9 meshes with the thread on the second threaded part 7. Then, the assembly rod 5 is rotated so that the second threaded part 7 and the threaded fixing part 12 are threadedly engaged. Compared with the prior art where the second threaded part 7 and the adjusting rod 8 are directly connected by threads, this assembly method is more convenient.

[0028] Specifically, after the tension link is assembled, if the length is suitable, by holding the assembly rods 5 at both ends and then rotating the adjusting rod, the adjusting rods at both ends are moved to the middle or to the sides at the same time to adapt to the installation length.

[0029] Preferably, the adjusting rod is polygonal in shape for easy turning.

[0030] Preferably, the fixed base 10 is fixedly installed on the inner wall of the adjusting rod, and the rotating plate 9 is installed on the fixed base 10 through a rotating shaft.

[0031] The connector 1 has an oil injection hole 14 on its side wall and a sealing plug 15 at the oil injection hole 14 to facilitate the injection of lubricating oil into the lubricating oil cavity 3.

[0032] The connector 1 is provided with a fastening bolt 16, which passes through the connector 1 and abuts against the first threaded portion 6. The contact point between the fastening bolt 16 and the first threaded portion 6 is provided with a pattern that is compatible with the first threaded portion 6.

[0033] The adjusting rod 8 is provided with fixing bolts 17 at both ends. The fixing bolts 17 pass through the side wall of the adjusting rod 8 and abut against the second threaded part 7. The fixing bolts 17 are provided with a pattern that is compatible with the second threaded part 7 at the contact point with the second threaded part 7.

[0034] In the above specific technical solution, when the tension link is assembled, tightening the fastening bolt 16 and the fixing bolt 17 can increase the stability of the tension link structure. The fastening principle of the fastening bolt 16 and the fixing bolt 17 is the same.

[0035] The above embodiments are merely exemplary embodiments of the present utility model and are not intended to limit the present utility model. The scope of protection of the present utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present utility model.
