[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In the present invention, it should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0025] A flexible tensioning device for a synchronous belt, such as Figure 1 - Figure 8 As shown, it includes a support 1, a slide groove 2 is provided on the support, a slider 3 fixed to the synchronous wheel mechanism is installed in the slide groove, a fixing seat 4 is fixedly installed on the support on one side of the slider, a connecting piece 5 extends from the slider toward the fixing seat side, and an adjusting bolt 6 extends from the fixing seat toward the connecting piece. An elastic device 7 is provided between the adjusting bolt and the connecting piece, which drives the slider to slide in the slide groove when the adjusting bolt moves toward the connecting piece. One end of the elastic device is connected to the adjusting bolt, and the other end is connected to the connecting piece.

[0026] like Figure 3 - Figure 6As shown, the chute is a trapezoidal chute that is narrow at the top and wide at the bottom, and the slider is a trapezoidal slider that is narrow at the top and wide at the bottom. By configuring the chute and slider in a trapezoidal shape with a narrow top and wide bottom, the slider can be embedded in the chute and is not easily dislodged during sliding, thereby securing the slider. Furthermore, the slider is provided with a screw hole 10 for securing the synchronous wheel mechanism. Screws for securing the synchronous wheel mechanism are inserted into the screw hole, and the screws are used to better secure the synchronous wheel mechanism 14 to the slider. Furthermore, a slider through-hole 11 is provided at the center of the slider for the synchronous wheel mechanism's rotating shaft to extend into, and a waist hole 12 is provided on the support for the synchronous wheel mechanism's rotating shaft to extend into. When the synchronous wheel mechanism is mounted on the slider, the synchronous wheel mechanism's rotating shaft extends from the slider through-hole 11 into the waist hole 12 of the support. As the slider slides, it drives the synchronous wheel mechanism's rotating shaft within the waist hole 12 to adjust the tension of the synchronous belt, providing a good guiding effect.

[0027] like Figure 7 and Figure 8 As shown, the fixed base 4 includes a base plate 41 and a side plate 42 connected to the base plate. The base plate is fixed to the support by bolts. The side plate is provided with a through hole 43 for the adjusting bolt to pass toward the connecting member. The adjusting bolt on the side plate facing away from the connecting member is mounted with a nut 8. By loosening the nut 8 of the adjusting bolt, the adjusting bolt is allowed to extend further through the through hole 43 in the side plate into the compression elastic device, thereby pushing the slider and the synchronous pulley mechanism to move, thereby gradually tightening the synchronous belt mechanism. After the elastic device is compressed to the required tension of the synchronous belt on the synchronous belt mechanism, the synchronous belt is tensioned. During operation or after a period of operation, if the synchronous belt shows signs of loosening or stretching, the nut 8 of the adjusting bolt is loosened to further increase the compression of the elastic device, thereby tensioning the synchronous belt, making operation more convenient. In addition, the support on the fixed base side is provided with a connecting lug 9. Securing the base plate to the bottom of the connecting lug with bolts 13 further saves space on the support and reduces interference with the adjusting bolt. In addition, a triangular reinforcing plate 44 inclined toward the support is provided between the bottom plate and the side plate. One side of the reinforcing plate is connected to the side plate, and the bottom side of the reinforcing plate is connected to the bottom plate. The reinforcing plate 44 can strengthen the connection between the fixed side plate and the bottom plate.

[0028] The elastic device adopts a spring or a compression spring, and the connecting piece adopts a stud. One end of the stud is fixed to one side of the slider, and the other end extends from the slider side and toward the fixed seat. Then one end of the spring is inserted into the adjusting bolt and connected with the adjusting bolt, and the other end is inserted into the stud and connected with the stud.

[0029] The above embodiments are merely illustrative of the detailed embodiments of the present invention. The present invention is not limited to the detailed embodiments described above, nor does it imply that the present invention must rely on the detailed embodiments described above in order to be implemented. Persons skilled in the art should understand that any improvements to the present invention, equivalent replacements of raw materials for the present invention, addition of auxiliary ingredients, and selection of specific methods, etc., fall within the scope of protection and disclosure of the present invention.
