In addition, the fixing base 20 and the adjusting plate 30 are respectively provided with a first matching portion and a second matching portion, the first matching portion and the second matching portion are matched, the adjusting plate 30 can be placed on the fixing base 20 according to different angles, and when the adjusting plate 30 is located at different angles, limiting components can be formed, so that the adjusting plate 30 is prevented from rotating relative to the fixing base 20 at corresponding positions, namely, the degree of freedom of rotation of the adjusting plate 30 around the axis O is limited. Specifically, a plurality of first matching parts are disposed on the protruding ribs 22, the first matching parts are specifically clamping grooves 23 formed by recessing the outer surfaces of the protruding ribs 22 towards the inner side of the bracket 10, the second matching parts are flanges 33 extending outwards from the periphery of the adjusting plate 30, and the flanges 33 can be matched and clamped into one of the clamping grooves 23, so that the flanges 33 are limited by utilizing two sides of the clamping grooves 23, and the purpose of limiting the rotation freedom degree of the adjusting plate 30 can be achieved. The bolt 50 crosses the bracket 10 along the Y direction and passes through the first long groove 21 on the fixing seat 20 at both sides of the bracket 10 and the second long groove 31 on the adjusting plate 30, the nut 51 of the bolt 50 is pressed on the outer side of one adjusting plate 30, the nut 60 is screwed on the other end of the bolt 50 and pressed on the outer side of the other adjusting plate 30, the two adjusting plates 30 are respectively pressed by the nut 51 and the nut 60 of the bolt 50, the freedom of moving the two adjusting plates 30 along the Y direction towards the direction far away from the bracket 10 is limited, in addition, a hole 12 with larger inner diameter is respectively arranged on the two side walls 11 of the bracket 10 for avoiding the bolt 50 when adjusting the transverse position of the bolt 50, the bolt 50 is sequentially passed through the adjusting plate 30 at one side, the fixing seat 20 and the fixing seat 20 at the other side, the adjusting plate 30 when being assembled, and then the nuts 60 are screwed down, and the two adjusting plates 30 are pressed into the grooves formed on the fixing seat 2.
Referring to fig. 4, in the initial installation, the extending direction of the second slot 31 of the adjusting plate 30 is aligned with the Z direction, the adjusting plate 30 is installed in the groove of the fixing base 20, the flange 33 on the adjusting plate 30 is clamped into the clamping groove 23 through the opening of the clamping groove 23 opposite to the flange 33, the nut 60 is tightened, and the adjusting plate 30 is pressed, at this time, the adjusting plate 30 and the fixing base 20 are kept fixed, at this time, the length direction of the second slot 31 is perpendicular to the length direction of the first slot 21, the second slot 31 is configured to limit the degree of freedom of the bolt 50 in the X direction, and the bolt 50 is limited at the position located in the middle of the first slot 21, namely, the bolt 50 is fixed through the overlapping region of the first slot 21 and the second slot 31. When the axle needs to be adjusted to the left, as shown in fig. 5, the nut 60 is loosened, the adjusting plate 30 is rotated around the axis O by a certain angle according to the clockwise direction, the flange 33 is clamped into the clamping groove 23 opposite to the adjusting plate, and when the adjusting plate 30 is rotated, the center line of the second long groove 31 is staggered by a certain distance from the axis O, namely, the second long groove 31 is eccentrically arranged on the adjusting plate 30, so that the side edge of the second long groove 31 presses the bolt 50 to the left, the bolt 50 moves to the left by a certain distance along the first long groove 21, then the rotating girder is pulled to the left by a certain distance by the bolt 50, the axle on the hanging girder moves to the left by a corresponding distance, and finally, the nut 60 is screwed, at this time, the overlapping area of the first long groove 21 and the second long groove 31 fixes the bolt 50, and the overlapping area is offset to the left side of the first long groove 21. Referring to fig. 6, when the axle needs to be adjusted to the right, the nut 60 is loosened, the adjusting plate 30 is rotated around the axis O by a certain angle according to the anticlockwise direction, the flange 33 is clamped into the clamping groove 23 opposite to the adjusting plate, the side edge of the second long groove 31 presses the bolt 50 to the right, the axle moves a certain distance to the right along with the bolt, finally the nut 60 is tightened, the overlapping area of the first long groove 21 and the second long groove 31 is shifted to the right side of the first long groove 21 and the bolt 50 is fixed, the axle adjusting distance is adjusted, and the rotating angle of the adjusting plate 30 can be determined according to the parallelism of the axle when in actual use, and then the flange 33 on the adjusting plate 30 needs to be clamped into the clamping groove 23 on the fixing seat 20.
In the above-mentioned scheme, by arranging a circle of circular protruding ribs 22 on the fixing seat 20, the limiting part 222 is formed by utilizing the inner edge surface of the protruding ribs 22, the degree of freedom that the adjusting plate 30 slides on the plane XZ is limited, and meanwhile, the adjusting plate 30 can be ensured to rotate around the axis O, furthermore, a plurality of clamping grooves 23 are arranged on the protruding ribs 22 as a plurality of first matching parts, and a flange 33 is arranged on the adjusting plate 30 as a second matching part matched with the first matching parts, because the flange 33 and the clamping grooves 23 are assembled along the Y direction in the drawing, i.e. the adjusting plate 30 and the fixing seat 20 have a certain matching size in the Y direction, and because the adjusting plate 30 is embedded into the clamping grooves 23, the distance of outward displacement of the adjusting plate 30 is larger than the depth of the clamping grooves 23, the limiting component formed by the flange 33 and the clamping grooves 23 can fail, i.e. the limiting effect of the adjusting plate 30 on the bolt 50 can fail, and then the bolt 50 can be caused to shake back and forth along the length direction of the first long groove 21, that is, the nut 60 is loosened slightly, and the adjusting plate 30 can still be limited by the fixing seat 20 and the position of the fixing seat 20 can not be still limited by the fixing seat 50, and the fixing seat 50 is still stably matched with the position; on the other hand, when the nut 60 is screwed down at the time of assembly or when the axle position is adjusted, since the rotation angle of the adjusting plate 30 is limited by the fixing base 20, the adjusting plate 30 does not follow rotation during the screwing down of the nut 60, so that the adjusting accuracy is not affected, that is, the position of the bolt 50 is fixed only after the adjusting plate 30 is rotated to the corresponding angle, and the screwing down of the nut 60 does not change the position of the bolt 50. In a word, compared with the prior art, the adjusting structure can adjust the position of the axle, so that the parallelism of the axle is adjusted, the adjusting plate cannot be displaced due to the running process of the vehicle, the axle can be kept fixed, and the shaking of the axle and the increase of wheel resistance are avoided; in addition, when assembling and adjusting, the axle position can be fixed only after the angle of the adjusting plate is fixed, so that the adjusting precision is improved.
