进一步的,头管1由三段以上的圆管组成,最下端圆管22以及次下端圆管21分别插入前叉根部孔26和前叉上管3内。Further, the head pipe 1 is composed of three or more round pipes, and the lowermost round pipe 22 and the lower lower end pipe 21 are inserted into the front fork root hole 26 and the front fork upper pipe 3, respectively.
进一步的,头管1中的最下端圆管22的外径略小于次下端圆管21,两圆管的轴心并不相同,二者的外径相切。Further, the outer diameter of the lowermost end pipe 22 in the head pipe 1 is slightly smaller than the lower end pipe 21, and the axial centers of the two pipes are not the same, and the outer diameters of the two pipes are tangent.
进一步的,前叉上管3内壁轴心与前叉根部孔26的轴心平行但不重合,前叉根部孔26的轴心较前叉上管3的内壁轴心稍向后叉方向偏移。Further, the inner wall axis of the front fork upper tube 3 is parallel to the axis of the front fork root hole 26 but does not overlap, and the axis of the front fork root hole 26 is slightly offset from the inner wall axis of the front fork upper tube 3 toward the rear fork direction. .
进一步的,头管1的最下端圆管可通过前叉上管3内壁后插入前叉根部孔26,并 利用其偏移量,通过旋转达到固定前叉上管3、前叉4及其自身的目的。Further, the lowermost end tube of the head pipe 1 can be inserted into the front fork root hole 26 through the inner wall of the front fork upper tube 3, and With its offset, the purpose of fixing the front fork upper tube 3, the front fork 4 and itself is achieved by rotation.
进一步的,通过前叉螺丝孔25固定在前叉上的弹簧止栓5由固定螺丝19、弹簧片27、插销20组成。Further, the spring stopper 5 fixed to the front fork through the front fork screw hole 25 is composed of a fixing screw 19, a spring piece 27, and a plug 20.
进一步的,插销20在弹簧片27的压力上插入前叉通孔24,随后与头管1相接触,头管最下端圆管23的适当位置设有通孔23,在旋转头管1以固定前叉4、前叉上管3及其自身的动作中,头管通孔23与弹簧止栓5的插销20重合,插销20在弹簧片27的压力下插入头管通孔23,达到防止头管1继续旋转和非正常拔出的目的。由于头管折叠单元的折叠操作主要由头管的旋转来完成,所以前叉上管3的铰轴管上设有止进凸起18,与之相对应的车架主梁6的主梁头管16的下端设有两个凸喙17。Further, the latch 20 is inserted into the front fork through hole 24 at the pressure of the spring piece 27, and then is in contact with the head pipe 1, and a through hole 23 is provided at a proper position of the lowermost end pipe 23 of the head pipe, and is fixed at the rotary head pipe 1 In the front fork 4, the front fork upper tube 3 and its own operation, the head tube through hole 23 coincides with the bolt 20 of the spring stopper 5, and the bolt 20 is inserted into the head tube through hole 23 under the pressure of the spring piece 27 to prevent the head. Tube 1 continues to rotate and the purpose of abnormal extraction. Since the folding operation of the head tube folding unit is mainly performed by the rotation of the head tube, the hinge tube of the front fork upper tube 3 is provided with a stopping protrusion 18, and the main beam head tube of the frame main beam 6 corresponding thereto is provided. The lower end of the 16 is provided with two tenons 17.
进一步的,在固定前叉折叠单元的操作中,头管1插入前叉上管3与前叉根部孔26,并带动前叉上管3和前叉4以主梁头管16轴心为轴进行旋转,当旋转到某一位置时,前叉上管3的止进凸起18与主梁头管16上的一个凸喙17相抵触,前叉上管3以及前叉4因此固定住,头管得以独立旋转,以止通过旋转达到固定头管1、前叉上管3和前叉的目的。Further, in the operation of fixing the front fork folding unit, the head pipe 1 is inserted into the front fork upper tube 3 and the front fork root hole 26, and the front fork upper tube 3 and the front fork 4 are driven to the main beam head tube 16 axis as an axis. Rotating, when rotated to a certain position, the retaining projection 18 of the front fork upper tube 3 is in contact with a tenon 17 on the main beam head tube 16, and the front fork upper tube 3 and the front fork 4 are thus fixed. The head tube is independently rotated to achieve the purpose of fixing the head pipe 1, the front fork pipe 3 and the front fork by rotation.
进一步的,当使用人要进行折叠前叉的操作时,只需向反方向旋转头管1,已固定的头管1带动前叉上管3、前叉4旋转到某一位置时,前叉上管3上的止进凸起18与另一个凸喙相抵触,前叉上管3和前叉4由止无法跟进旋转,同时固定在前叉4上的弹簧止栓5的弹簧片27上端与另一端的凸喙17接触,并在这一凸喙17的作用下弹起,带动插销20抽离头管通孔23,由此,在两个因素的同时作用下,头管得以继续旋转,松动头管1、前叉上管3、前叉4之间的固定,并拔出,而后前叉4以前叉铰轴10为轴进行折叠动作。Further, when the user wants to perform the operation of folding the front fork, it is only necessary to rotate the head pipe 1 in the opposite direction, and the fixed head pipe 1 drives the front fork upper tube 3 and the front fork 4 to rotate to a certain position, the front fork The retaining projection 18 on the upper tube 3 is in contact with the other tenon, and the front fork upper tube 3 and the front fork 4 are rotated by the spring tab 27 of the spring stop bolt 5 which is fixed to the front fork 4. The upper end is in contact with the tenon 17 at the other end, and is bounced under the action of the tenon 17 to drive the bolt 20 away from the head tube through hole 23, whereby the head tube can continue under the action of two factors. The rotation, the loose head tube 1, the front fork upper tube 3, and the front fork 4 are fixed and pulled out, and the rear front fork 4 is folded by the front fork hinge shaft 10 for the shaft.
在通过双手分别控制坐杆7的拔插以及头管1的旋转后,后叉9和前叉4得以向主梁6方向纵向折叠,随后坐杆7和头管1完全拔出并放入折叠后的前叉4后叉9之间的空隙内,完成折叠动作。After the insertion and removal of the seat bar 7 and the rotation of the head pipe 1 are separately controlled by both hands, the rear fork 9 and the front fork 4 are longitudinally folded toward the main beam 6, and then the seat bar 7 and the head pipe 1 are completely pulled out and placed in a folded state.
