[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1-5 A highly stable anti-jamming tensioner structure includes a tensioner body 1, a webbing 2 at one end of the tensioner body 1, an extension frame 3 fixedly connected to the end of the tensioner body 1 away from the webbing 2, positioning shafts 4 fixedly connected to the top and bottom of the end of the extension frame 3 away from the tensioner body 1, support arms 5 rotatably connected to the outer sides of the two positioning shafts 4, a cleaning component 6 assembled at the end of the support arm 5 away from the positioning shafts 4, the cleaning component 6 being used to remove impurities from the surface of the webbing 2, and an adjustment component 7 provided on the inner side of the extension frame 3, the adjustment component 7 being used to adjust the working position of the cleaning component 6;

[0027] In this embodiment, the tensioner body 1 mainly consists of a metal head, a mechanical rocker arm, a locking mechanism and an end connector. It drives the winch to rotate through the mechanical rocker arm and gradually tightens the webbing 2. This is a mature existing technology and will not be described in detail here.

[0028] The cleaning assembly 6 includes a mounting shaft 8 and a cleaning roller 9. The cleaning roller 9 is sleeved on the outside of the mounting shaft 8. A limiting strip 10 is fixedly connected to the outside of the mounting shaft 8. A limiting groove 11 is opened on the inner wall of the cleaning roller 9, and the limiting strip 10 is also slidably connected inside the limiting groove 11. A displacement plate 12 is slidably connected inside the limiting groove 11. A plurality of locking plates 13 are fixedly connected to the top of the displacement plate 12, and the locking plates 13 pass through the limiting strip 10 and are snapped into the inside of the limiting groove 11. A linkage rod 14 is rotatably connected to the middle of the bottom end of the displacement plate 12. A transmission screw 15 is rotatably connected to the bottom end inside the mounting shaft 8. A displacement block 16 is threadedly connected to the outside of the transmission screw 15, and the end of the linkage rod 14 away from the displacement plate 12 is also rotatably connected to the inside of the displacement block 16.

[0029] In this embodiment, multiple sets of brushes are fixedly connected to the outer side of the cleaning roller 9, and each set of brushes has no less than ten brushes. By setting the brushes, after the webbing 2 comes into contact with the brushes, the brushes can remove impurities on the webbing 2, thus avoiding the presence of impurities that could cause the webbing to jam.

[0030] In this embodiment, the inner wall of the limiting groove 11 is provided with multiple locking grooves, and the locking plate 13 is snapped into the inside of the locking groove. By setting the locking groove, after the locking plate 13 moves out of the limiting strip 10, it can move into the inside of the locking plate 13, thereby locking the position of the cleaning roller 9 and preventing the cleaning roller 9 from moving uncontrollably.

[0031] In this embodiment, a force-receiving knob is rotatably connected to one end of the shaft 8, and the end of the transmission screw 15 near the force-receiving knob is fixedly connected to the force-receiving knob. The force-receiving knob has an internal hexagonal groove in the middle. By setting the force-receiving knob, the operator can easily rotate the transmission screw 15 with the help of an internal hexagonal wrench, ensuring the transmission effect of the transmission screw 15 and making the whole process more convenient.

[0032] Example 2:

[0033] Please see Figure 1-5 This embodiment provides a technical solution based on embodiment one: the adjustment component 7 includes a support screw 17 and a linkage seat 19. The inner side of the extension frame 3 is rotatably connected to the support screw 17, and the outer side of the support screw 17 is threadedly connected to the displacement frame 18. The top and bottom ends of the displacement frame 18 are fixedly connected to the linkage seat 19. The middle of the two support arms 5 is provided with a linkage through groove 20, and one end of the two linkage seats 19 is movably connected to the inside of the two linkage through grooves 20 respectively.

[0034] In this embodiment, a linear guide rod is fixedly connected to the inner side of the extension frame 3, and the displacement frame 18 is also slidably connected to the outer side of the linear guide rod. By setting the linear guide rod, the displacement of the displacement frame 18 can be effectively limited, ensuring the stability of the displacement of the displacement frame 18.

[0035] In this embodiment, a linkage pin is fixedly connected to one end of the linkage seat 19, and the linkage seat 19 is movably connected to the inside of the linkage channel 20 through the linkage pin. By setting the linkage pin, during the process of the linkage seat 19 following the displacement frame 18, the linkage pin can be driven to make adaptive displacement in the linkage channel 20, thereby driving the support arm 5 to make adaptive rotation under the support of the positioning shaft 4.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] Working principle: Before the free end of the webbing 2 is connected to the tensioner body 1, the free end of the webbing 2 is first passed between the two cleaning rollers 9. When the tensioner body 1 winds up the webbing 2, the cleaning rollers 9 can contact the webbing 2 to remove impurities from the webbing 2, thereby ensuring smoothness during subsequent winding and avoiding tape jamming.

[0038] Furthermore, when the cleaning roller 9 is not performing well, the transmission screw 15 is rotated. In conjunction with the connection between the transmission screw 15 and the displacement block 16, the displacement block 16 can be moved along the transmission screw 15. Since the linkage rod 14 is connected between the displacement block 16 and the displacement plate 12, when the displacement block 16 moves linearly, the linkage rod 14 can pull the displacement plate 12, causing the locking plate 13 to disengage from the limit groove 11, thereby unlocking the cleaning roller 9. Then, the cleaning roller 9 can be removed from the mounting shaft 8 and replaced.

[0039] Since the presence of the cleaning roller 9 will affect the winding efficiency of the webbing 2, when the webbing 2 does not need to be cleaned, the support screw 17 is rotated. With the connection between the support screw 17 and the displacement frame 18, the displacement frame 18 can be moved along the support screw 17, and the support arm 5 is pushed to rotate under the support of the positioning shaft 4 through the linkage seat 19, so that the distance between the two cleaning rollers 9 increases. As a result, when winding the webbing 2, the webbing 2 will not fully contact the cleaning roller 9, thereby ensuring the winding efficiency of the webbing 2.
