[0010] Example 1: Figure 1 As shown, a steering limit structure of a shock-absorbing front fork of a scooter includes a core shaft 1, a neck tube 2, a limit bolt 3, a nut 4, a left shock absorber 5, a right shock absorber 6, a bearing 7, an open groove 8, a limit piece 9, a lower bolt 10, a dust cover 11, a bolt through hole 12, a connecting piece 13 and a positioning hole 14.
[0011] The spindle 1 is a rotating part, the upper end of the spindle 1 is connected to the handlebar stem, the lower end of the spindle 1 has a positioning hole 14, the lower end of the spindle 1 is connected to the connecting piece 13 by welding, and the two sides of the connecting piece 13 are respectively connected to the left shock absorber 5 and the right shock absorber 6 to form a rotating shock-absorbing front fork.
[0012] The function of the positioning hole 14 is to match the bolt through hole 12 in the neck tube 2. The limiting bolt 3 penetrates the bolt through hole 12 in the neck tube 2 and the positioning hole 14 in the core shaft 1, and also penetrates the opening groove 8 in the limiting member 9 and is then tightened and fixed by the lower bolt 10; when the lower end of the core shaft 1 is connected to the connecting member 13 by welding, the two sides of the connecting member 13 are respectively connected to the left shock absorber 5 and the right shock absorber 6 to form a rotating shock-absorbing front fork, the bearing 7 is penetrated from the core shaft 1, and then Insert the limiting member 9 into the core shaft 1, and then into the neck tube 2, align the limiting bolt 3 with the bolt through hole 12 in the neck tube 2, insert it into the opening groove 8 in the limiting member 9 and continue to insert it into the positioning hole 14 in the core shaft 1, and insert the lower bolt 10 into the other side of the bolt through hole 12 in the neck tube 2 from the other side (the bolt through hole 12 is a through hole), and the top of the lower bolt 10 is inserted into the other side of the hole 14 in the core shaft 1, and finally locked with the limiting bolt 3 to form a tightening.
[0013] At this time, the rotation direction of the front fork is completely realized by utilizing the limit bolt 3 in the open groove 8 in the limit member 7 to realize left and right rotation so as to achieve the limit. The limiting member 9 is a cylindrical tubular shape, and the outer circumference of the limiting member 9 coincides with the inner cavity diameter of the neck tube 2. The outer circumference of the limiting member 9 is connected to the inner cavity of the neck tube 2. An open groove 8 is provided on one side of the limiting member 9, and a bolt through hole 12 is provided in the radial direction of the circumference of one end of the neck tube 2. The limiting bolt 3 is spirally connected to the bolt through hole 12 on one side, and the other end of the limiting bolt 3 is embedded in the open groove 8. The open groove 8 matches the limiting bolt 3 to achieve limiting. The dust cover 11 is covered on the screw hole 12, the core shaft 1 passes through the neck tube 2, the bearing 7 and the limiting member 9, the bearing 7 and the limiting member 9 are connected to the neck tube 2, the lower bolt 10 is connected to the bolt through hole 12 on the other side of the neck tube 2, and the limiting member 9 is fixed in the inner cavity of the neck tube 2 by the lower bolt 10. The holes at both ends of the connecting member 13 are used to fix the left shock absorber 5 and the right shock absorber 6 respectively, and the left shock absorber 5 and the right shock absorber 6 are locked by the nut 4.
[0014] The connecting member 13, the left shock absorber 5 and the right shock absorber 6 are driven by the rotating core shaft 1. When the connecting member 13, the left shock absorber 5 and the right shock absorber 6 are rotated to a certain angle and a limit angle, when the limit angle is reached, one side of the opening slot 8 of the limit member 9 conflicts with the limit bolt 3 to achieve the limit. When the connecting member 13 is rotated in the opposite direction, the limit position of the opening slot 8 in the side direction conflicts with the limit bolt 3 to achieve the limit.

The limiter is designed to be a cylindrical tube, the size of which matches the diameter of the inner cavity of the neck tube, and an open groove is designed on one side of the limiter, and the open groove matches the limit bolt to realize the limit. The holes at both ends of the connector are used to fix the shock absorber and are locked by nuts. The limiter penetrates the mandrel and then penetrates the neck tube, aligns with the fixed hole, and fixes the limiter in the inner cavity of the neck tube by bolts, and then presses the upper limit bolt, and finally covers the decorative cover. The connector and the shock absorber are driven by rotating the mandrel. When the limit angle is reached when the limit angle is reached, the open groove of the limiter conflicts with the limit bolt to realize the limit. When rotating in the opposite direction, it can rotate flexibly. When rotating in the opposite direction to the limit angle, the limit position of the side opening slot conflicts with the limit bolt to achieve limit.
