It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0018] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0019] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0020] Reference Figure 1-4, an automatically repairable belt tensioner, comprising a fixed hook 1 installed on a movable sliding door, an adjusting component 2 is installed above the fixed hook 1 through at least two first rivets 3, a connecting piece 5 adjusted by an adjusting spring 4 is installed in the adjusting component 2, an installation gap is arranged between the adjusting component 2 and the fixed hook 1, a sliding piece 6 fixed to the connecting piece 5 is slidably installed in the installation gap, a waist-shaped hole 7 is arranged on the sliding piece 6 corresponding to the first rivet 3, the waist-shaped hole 7 is sleeved on the first rivet 3, a guide wheel 8 is installed at the end of the sliding piece 6, when the belt is stretched and loosened after long-term use, the position of the guide wheel is adjusted instantly by spring adjustment, so that the belt can always be kept in a tensioned state without additional adjustment.

[0021] The adjustment assembly 2 includes a mounting seat 9 with through holes at both ends, an adjusting screw 10, and an adjusting nut 11. The mounting seat 9 is provided with a mounting groove 12 with an upper opening. The mounting groove 12 is used to install the adjusting nut 11, the adjusting spring 4 and the connecting piece 5 in sequence from left to right. The adjusting screw 10 is inserted from the left side of the mounting seat 9, passes through the adjusting nut 11, the adjusting spring 4 and the connecting piece 5 in sequence, and extends from the right side of the mounting seat 9. The adjusting nut 11 is threadedly connected to the adjusting nut 11.

[0022] The bottom of the mounting seat 9 is provided with a square hole for mounting the connecting member 5 . The connecting member 5 is inserted from the bottom of the mounting seat 9 into the mounting groove 12 through the square hole. The square hole is required not to restrict the movement of the connecting member 5 .

[0023] The end of the adjusting screw 10 outside the right side of the mounting seat 9 is provided with an embedding groove 13, and a fixed retaining ring 14 is installed on the embedding groove 13 to prevent the adjusting screw 10 from being pushed out of the mounting seat 9 due to the action of the adjusting spring 4.

[0024] The sliding member 6 is provided with a first mounting hole 15 , and the connecting member 5 is provided with a second mounting hole 16 corresponding to the first mounting hole 15 . The first mounting hole 15 and the second mounting hole 16 are fixed to each other via a second rivet 17 .

[0025] The sliding member 6 is provided with a positioning hole 18 , and the bottom of the connecting member 5 is provided with a positioning protrusion 19 corresponding to the positioning hole 18 , and the positioning protrusion 19 is inserted into the positioning hole 18 .

[0026] The connecting member 5 is an "L"-shaped member, and is composed of a transverse portion and a vertical portion. The second mounting hole 16 and the positioning protrusion 19 are arranged on the transverse portion, and a circular hole for penetrating the adjusting nut 11 is arranged on the vertical portion.

[0027] During the installation process of this product: first, fix the connecting member 5 and the sliding member 6 (the guide wheel 8 is already installed on the sliding member 6), then stack the fixed hook 1, the sliding member 6 and the mounting seat 9 from bottom to top, and then use the first rivet 3 to fix the fixed hook 1 and the mounting seat 9 (the first rivet 3 needs to pass through the waist-shaped hole 7). At this time, the connecting member 5 has been inserted into the mounting groove 12 of the mounting seat 9 through the square hole, and then the adjusting nut 11 and the adjusting spring 4 are placed in the mounting groove 12 (from left to right, the adjusting nut 11, the adjusting spring 4 and the vertical part), insert the adjusting screw 10 from the left side of the mounting seat 9, pass through the adjusting nut 11, the adjusting spring 4 and the vertical part in turn, and extend from the right side of the mounting seat 9, and then install the fixed retaining ring 14 in the embedding groove 13, and the installation is completed at this time.

[0028] The debugging process of this product: first, rotate the adjusting nut 11 to move the adjusting nut 11 in the direction of the adjusting spring 4, and push the sliding member 6 to the right through the connecting member 5 until the adjusting spring 4 is in a compressed state. At this time, the sliding member 6 is pushed to the far right, that is, the first rivet 3 is located at the left end of the waist-shaped hole 7, and the belt is sleeved on the guide wheel 8 (at this time, this product has been installed on the linked sliding door), and the belt is preliminarily tightened. At this time, the position of the guide wheel 8 has not changed, and the belt continues to be tightened to move the guide wheel 8 to the left until the first rivet 3 is located in the middle of the waist-shaped hole 7 (it can also be until the first rivet 3 is located at the right end of the waist-shaped hole 7 to increase the adjustment limit, and the installation worker needs to flexibly adjust according to the actual situation). At this time, the belt adjustment is completed, and finally the two ends of the belt can be fixed.

[0029] When the belt is stretched, the adjusting spring 4 pushes the connecting member 5 to the right, and then pushes the guide wheel 8 to the right, thereby compensating for the distance the belt is stretched, so that the belt can be used to maintain a tensioned state.
