[0029] like Figures 1 to 9 As shown, a linkage belt locking structure includes a base 1, a locking member 2 and a linkage belt 3. The linkage belt 3 includes a belt body 31 and belt teeth 32. The linkage belt 3 has an overlapped portion 33 formed by partially overlapping a small length of the belt body 31, and the belt teeth 32 are arranged on the outside of the overlapped portion 33. In the overlapped portion 33, two belt bodies 31 are attached to each other on the inner side, and the position of the overlapped portion 33 can be formed by folding the closed linkage belt 3, or by overlapping the opened linkage belt 3 at two end positions. The linkage belt 3 is locked at the overlapped portion 33, and after being locked, the linkage belt 3 is in a closed ring shape as a whole.

[0030] The base 1 includes a first buckle plate 11, which is provided with a through hole 111. The overlapping portion 33 passes through the through hole 111, that is, the width of the through hole 111 is greater than the sum of twice the thickness of the belt body 31 and twice the height of the belt teeth 32. Both the belt body 31 and the belt teeth 32 of the overlapping portion 33 can pass through the through hole 111.

[0031] The lock member 2 includes a second buckle portion 21, which is relatively fixed to the first buckle plate 11 in the length direction of the stacking portion 33. The second buckle portion 21 is provided with a buckle hole 211 that can only accommodate the two belt bodies 31 of the stacking portion 33, that is, the belt teeth 32 cannot pass through the buckle hole 211, and the buckle hole 211 is provided with an opening 212 that can allow the two belt bodies 31 of the stacking portion 33 to pass through. The two belt bodies 31 of the stacking portion 33 pass through the buckle hole 211, and the belt teeth 32 of the stacking portion 33 are arranged on the outside of the buckle hole 211. Figure 5 The second buckle portion 21 is clamped between two adjacent belt teeth 32 , and the second buckle portion 21 cannot pass through the through hole 111 .

[0032] When installing the linkage belt 3, the linkage belt 3 is partially overlapped to form an overlapped portion 33, referring to Figure 3 , insert the overlapping portion 33 into the through hole 111 of the first buckle plate 11 of the base 1, and then move the second buckle portion 21 of the locking member 2 close to the overlapping portion 33 from the opening 212, and the belt body 31 between two adjacent belt teeth 32 enters the buckle hole 211 from the opening 212, so that the second buckle portion 21 is clamped between the two adjacent belt teeth 32, and at least one belt tooth 32 on one side of the overlapping belt body 31 is in the through hole 111. In addition, the first buckle plate 11 and the second buckle portion 21 are also relatively fixed in the length direction of the overlapping portion 33.

[0033] The locking structure uses the first buckle plate 11 and the second buckle part 21 and the second buckle part 21 and the linkage belt 3 to fix in the length direction of the overlapped part 33, so as to lock the linkage belt 3 with the through hole 111 of the base 1. It is not necessary to use screws to tighten and lock the linkage belt 3, and the installation operation is relatively simple. In addition, the linkage belt 3 extends separately on both sides of the overlapped part 33. Figure 1 , the overlapping portion 33 and the locking member 2 can be closer to the pulley.

[0034] In some specific embodiments, an anti-slip portion is provided at the opening 212 , and the anti-slip portion can prevent the stacked portion 33 from slipping out of the opening 212 .

[0035] After the overlapped portion 33 enters the button hole 211, the overlapped portion 33 is not easy to escape from the opening 212 under the limiting effect of the anti-escape portion, so that the overlapped portion 33 is kept in the button hole 211 during operation, thereby improving the stability of the locking linkage belt 3. In other embodiments, the width of the button hole 211 can also be set to be slightly less than twice the width of the belt body 31, so that the belt body 31 and the button hole 211 are tightly connected by interference fit, which can also achieve the anti-escape effect.

[0036] Furthermore, the anti-slip portion is an anti-slip protrusion 213, which is arranged on the second buckle portion 21, and the anti-slip protrusion 213 protrudes toward the inner side of the opening 212. After the overlapping portion 33 of the linkage belt 3 enters the buckle hole 211, the anti-slip protrusion 213 is at least partially outside the linkage belt 3 to block the linkage belt 3. Although the anti-slip protrusion 213 will also hinder the belt body 31 of the overlapping portion 33 from entering, since the belt body 31 has a certain elasticity, the belt body 31 can be compressed when the belt body 31 enters the opening 212 by hand, and the belt body 31 can rebound after entering the buckle hole 211, and the anti-slip protrusion 213 can prevent the overlapping portion 33 from escaping. When the linkage belt 3 needs to be disassembled, the opening 212 can be opened with a tool to facilitate the removal of the linkage belt 3. In other embodiments, the anti-detachment portion can be a rotating bar arranged next to the opening 212, one end of the rotating bar is rotatably connected to the second buckle 21 on one side of the opening 212, and the other end of the rotating bar can be rotated to the other side of the opening 212 and snapped to close the opening 212.

[0037] Furthermore, a recess 214 is provided at the opening 212, and the recess 214 is provided on the opposite side of the anti-slipping protrusion 213. Since the anti-slipping protrusion 213 may hinder the linkage belt 3 from entering the buckle hole 211, the recess 214 is provided on the opposite side of the anti-slipping protrusion 213 to increase the distance between the anti-slipping protrusion 213 and facilitate the linkage belt 3 to pass through the opening 212.

[0038] Furthermore, the lower side of the anti-slip protrusion 213, the lower side of the recess 214 and the upper side of the recess 214 are all provided with rounded corners 215. The rounded corners 215 can facilitate the linkage belt 3 to enter the opening 212 more smoothly.

[0039] The structure of the locking member 2 may refer to the following embodiments 1, 2 and 3, or other structures that can achieve relative fixation of the second buckle portion 21 and the first buckle plate 11 in the length direction of the overlapping portion 33 .

[0042] After the overlapped portion 33 enters the buckle hole 211, the two second buckle plates 23 of the lock fastener 2 are on both sides of the first buckle plate 11 of the base 1, so that the second buckle portion 21 and the first buckle plate 11 are relatively fixed in the length direction of the overlapped portion 33, and the structure is relatively simple.
