[0024] The present application will be further described in detail below in combination with the drawings and specific embodiments:Figures 1-6 The head pipe adjusting structure for motorcycle simulation test bench comprises a support frame 1, a head pipe 2 and a locking piece 3. The support frame 1 is arranged on the test bench. The support frame 1 comprises left and right support plates. The support piece 11 is fixedly arranged on the left and right support plates. The head pipe 2 is assembled on the support piece 11 and can rotate on the support piece 11.

[0025] The support piece 11 can be a pipe. The pipe comprises a polygonal pipe and a circular pipe. The head pipe 2 is transversely provided with a first groove 21. The first groove 21 is matched with the support piece 11. The head pipe 2 is further provided with a first plane 25. The locking piece 3 is provided with a second groove 31 and a second plane 34. The head pipe 2 is pressed on one side of the support piece 11 through the first groove 21. The locking piece 3 is pressed on the other side of the support piece 11 through the second groove 31. The head pipe 2 and the locking piece 3 are pressed on the support piece 11 from the front and back directions of the support piece 11. The first plane 25 and the second plane 34 are oppositely arranged and face the support piece 11.

[0026] The locking piece 3 is provided with a through hole 33. The head pipe 2 is provided with a fastening hole 24 at the corresponding position. The fastening hole 24 is provided with a thread. A fastening piece 32 is screwed on the fastening hole 24 through the through hole 33 of the locking piece 3. The tail end of the fastening piece 32 is pressed on the outer end of the locking piece 3. The gap between the first plane 25 and the second plane 34 can be adjusted by screwing the fastening piece 32. Thus, the pressing force of the locking piece 3 and the head pipe 2 on the support piece 11 can be adjusted. When the pressing force is large, the locking piece 3 and the head pipe 2 are locked on the support piece 11. The head pipe 2 cannot rotate. When the pressing force is small, the head pipe 2 can rotate on the support piece 11.

[0027] When the head pipe 2 and the locking piece 3 are locked on the support piece 11, the gap between the first plane 25 of the head pipe 2 and the second plane 34 of the locking piece 3 is greater than 1mm and less than 10mm. The locking piece 3 is provided with four through holes 33. Two of the through holes 33 are above the second groove 31. The other two through holes 33 are below the second groove 31. The head pipe 2 is provided with four fastening holes 24. Two of the fastening holes 24 are above the first groove 21. The other two fastening holes 24 are below the first groove 21. The four fastening holes 24 are provided with fastening pieces 32. The head pipe 2 and the locking piece 3 are fastened on the support piece 11 through the four fastening pieces 32.

[0028] Wherein the two fasteners 32 below the second groove 31 are loosened, the locking force of the locking piece 3 and the head tube piece 2 on the support piece 11 is reduced, and the head tube piece 2 can rotate on the support piece 11.

[0029] Wherein the support piece 11 is a circular pipe, loosening the fastener 32 can realize the free rotation of the head tube piece 2 on the support piece 11. Since the support piece 11 is a circular pipe, the head tube piece 2 rotates on the support piece 2 without gears, that is, it realizes stepless adjustment.

[0030] Wherein the support piece 11 is a regular polygon pipe, the first groove 21 is a circular arc groove, which can be buckled on one side of the polygon pipe. Loosening the fastener 32, the head tube piece 2 can also rotate freely on the support piece 11. However, when the head tube piece 2 is pressed on the support piece 11 with the locking piece 3, the contact area between the head tube piece 2 and the support piece 11 is small, so the friction is small, and thus it is easy to slip. Therefore, the support piece 11 is preferably a circular pipe.

[0031] The support frame 1 is provided with a cover piece 12 for shielding the support frame 1 through a threaded piece. The upper end of the cover piece 12 is provided with a long slot hole 121. The upper end of the head tube piece 2 extends upward from the long slot hole 121. When the head tube piece 2 rotates on the support piece 11, the upper end of the head tube piece 2 moves in position. The long slot hole 121 provides a space for the upper end of the head tube piece 2 to avoid contact with the cover piece 12 when the head tube piece 2 rotates.

[0032] The cover piece 12 is also provided with a work hole 122. The position corresponding to the work hole 122 is the position of the locking piece 3. A shielding plate 123 is assembled on the work hole 122. The shielding plate 123 can be rotatably arranged at the lower end of the work hole 122, and the upper end is locked in the upper end of the work hole 122 by buckling. Thus, when adjustment is needed, the shielding plate 123 can be quickly opened to adjust the head tube piece 2 in the work hole 122, and the shielding plate 123 can also be locked on the work hole 122 by screwing. The shielding plate 123 is mainly used to make the cover piece 12 complete and the overall appearance beautiful. It can be quickly disassembled when adjusting, and thus the adjustment of the head tube piece 2 can be quickly realized.

[0033] The upper end of the head tube piece 2 is longitudinally provided with a mounting hole 22 for mounting a handle frame, and the outer wall is also provided with a limiting plate 23 for limiting the rotation angle of the handle frame.

[0034] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features therein can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
