At least a portion of the mounting plate 2 and at least a portion of the fixing plate 1 are stacked in a second direction. The tensioning wheel 3 is rotatably arranged on the mounting plate 2, and the rotation axis of the tensioning wheel 3 extends along the second direction. Specifically, the tensioning wheel 3 is arranged on the side of the mounting plate 2 away from the fixing plate 1. The mounting plate 2 is connected to the fixing plate 1, and the relative position of the mounting plate 2 and the fixing plate 1 along the first direction is adjustable, so as to adjust the relative position of the tensioning wheel 3 and the fixing plate 1 in the first direction, wherein the first direction is perpendicular to the second direction.

[0037] It should be noted that the second direction is along Figure 2 The first direction is the axial direction of the tension wheel 3 or the thickness direction of the mounting plate 2. Figure 2 The length direction of the mounting plate 2 shown in the figure, the third direction is along Figure 2 The width direction of the mounting plate 2 is shown.

[0038] Among them, Figure 1 As shown, the transmission device 200 includes a first transmission shaft 201 and a second transmission shaft 202 which are spaced apart and arranged in parallel, and a transmission member 203, the transmission member 203 is sleeved on the first transmission shaft 201 and the second transmission shaft 202, and the transmission member 203 can be a transmission belt or a transmission chain. The tensioning wheel 3 can be connected to one of the transmission shafts (the first transmission shaft 201 or the second transmission shaft 202) of the transmission device 200, and adjust the distance between the first transmission shaft 201 and the second transmission shaft 202, so as to adjust the tension of the transmission belt or the transmission chain, and the tensioning wheel 3 can also cooperate with the transmission belt or the transmission chain of the transmission device 200 and be located between the first transmission shaft 201 and the second transmission shaft 202, and adjust the distance that the transmission belt or the transmission chain on the transmission device 200 moves in a certain direction, so as to adjust the tension of the transmission belt or the transmission chain.

[0039] In addition, if Figure 2 As shown, the adjusting member 4 extends along the first direction, is connected to the fixing plate 1 and abuts against the mounting plate 2, and is used to adjust the relative position of the fixing plate 1 and the mounting plate 2 in the first direction. The adjusting member 4 is threadedly connected to the fixing plate 1. When the relative position of the fixing plate 1 and the mounting plate 2 in the first direction is adjusted by the adjusting member 4, the adjusting member 4 can be rotated, and the adjusting member 4 moves along the first direction while the fixing plate 1 remains in position. Since the adjusting member 4 abuts against the mounting plate 2, the mounting plate 2 can move in the moving direction of the adjusting member 4, thereby realizing the adjustment of the relative position between the mounting plate 2 and the fixing plate 1 in the first direction, thereby realizing the adjustment of the tensioning wheel 3, and meeting the tensioning requirements of the transmission device 200.

[0040] like Figure 2As shown, the locking member 5 extends along the first direction, and the locking member 5 is used to connect the fixing plate 1 and the mounting plate 2. The locking member 5 can limit and fix the fixing plate 1 and the mounting plate 2 in the first direction. The fixing member 6 extends along the second direction, and the fixing member 6 is used to connect the fixing plate 1 and the mounting plate 2. The fixing member 6 can limit the fixing plate 1 and the mounting plate 2 in the second direction.

[0041] Optionally, the adjusting member 4, the locking member 5 and the fixing member 6 may all be bolts.

[0042] Among them, before the adjusting member 4 adjusts the relative position of the mounting plate 2 and the fixing plate 1, it is necessary to loosen or remove the locking member 5 and the fixing member 6 first. After the adjusting member 4 is adjusted into place, that is, the mounting plate 2 is adjusted into place relative to the fixing plate 1, it is necessary to tighten the locking member 5 and the fixing member 6, or install the locking member 5 and the fixing member 6 and then tighten them.

The third fastener 301 can move relatively in the fixing hole 18 along the length direction of the fixing hole 18, so as to adjust the relative position of the third fastener 18 and the fixing plate 1 in the second direction, thereby adjusting the position of the entire tensioning device 100 relative to the fixing device or the fixing component 300 in the second direction, so as to better match with the transmission device.

The first adjusting portion 13 and the second adjusting portion 23 are respectively arranged on the same side of the fixing body 12 and the mounting body 22 along the second direction and are arranged opposite to each other in the first direction. Among them, the first adjusting portion 13 and the fixing body 12 are arranged vertically, the second adjusting portion 23 and the mounting body 22 are arranged vertically, a part of the fixing body 12 exceeds the mounting body 22 in the first direction, and the first adjusting portion 13 is connected to the part of the fixing body 12 that exceeds the mounting body 22, so as to achieve an opposite arrangement with the second adjusting portion 23 in the first direction.

[0053] The adjusting member 4 is passed through the first adjusting portion 13 and abuts against the second adjusting portion 23, and the locking member 5 is passed through the first adjusting portion 13 and the second adjusting portion 23, thereby facilitating the arrangement of the adjusting member 4 and the locking member 5, and facilitating the adjusting member 4 to abut against the mounting plate 2 in the first direction, and facilitating the locking member 5 to connect the mounting plate 2 and the fixing plate 1 along the first direction.

In addition, the plurality of adjusting members 4 can better drive the mounting plate 2 to move, thereby adjusting the relative position of the mounting plate 2 and the fixing plate 1, and thus adjusting the position of the tensioning wheel 3.
