In the preferred embodiment, a spring 12 is provided on the straight rod section 13, the straight rod section 13 passes through the retaining ring 11, and the lower end thereof is connected to the transition rod 14. .

在立管 6的上部，在立管内设置一便于销杆 10插入销孔 7的引导 件 9。 销孔 7是与销杆 10的锥形段相配合的锥形孔。  On the upper part of the riser 6, a guide 9 is provided in the riser to facilitate the insertion of the pin 10 into the pin hole 7. The pin hole 7 is a tapered hole that cooperates with the tapered section of the pin shaft 10.

将连接转板 15与自行车阴管 21相固定的方式可以是任何形式， 其要求是保证连接转板 15绕铰接轴 16转动。 本实用新型所使用的方 法为， 在连接转板 15上开有一便于锁紧杆 18的横销 1^ 插入的横孔 20。 锁紧杆 18可转动地安装底座 25上， 底座 25通过螓钉 24固定在 自行车阴管 21上。  Any method can be used to fix the connecting rotating plate 15 and the bicycle tube 21, and the requirement is to ensure that the connecting rotating plate 15 rotates about the hinge shaft 16. The method used in the present invention is that a horizontal hole 20 is formed on the connecting rotating plate 15 for the insertion of a horizontal pin 1 ^ of the locking lever 18. The locking lever 18 is rotatably mounted on the base 25, and the base 25 is fixed on the bicycle tube 21 by a nail 24.

图 1和 3为车把处于锁紧状态，锁紧杆 18的横销 1— 9¾1入转板 15 的开孔 20内， 此时， 阴筒 21与立管 6成一直线， 销杆 10在弹簧 12 的作用下处于释放状态， 销杆 10的锥形段插入销孔 7内， 车把转轴 2 不能在转套 3内转动。  Figures 1 and 3 show the handlebars in the locked state. The horizontal pins 1-9¾1 of the locking lever 18 enter the openings 20 of the swivel plate 15. At this time, the female tube 21 is aligned with the riser 6, and the pin 10 is in the spring. In the release state under the action of 12, the tapered section of the pin 10 is inserted into the pin hole 7, and the handlebar rotating shaft 2 cannot rotate in the rotating sleeve 3.

图 2为车把处于折叠状态，锁紧杆 18的横销 19从转板 15的开孔 20中转出， 立管 6可绕铰接轴 16向内侧转动 90度， 由于铰接轴 16 和销钉 17之间有一定的距离，在立管 6绕轴 16转动时，销杆 10被逐 渐拉紧， 销杆 10被从销孔 7中拉出， 此时， 车把转轴 2可以在转套 3 内在 360度的范围转动。 FIG. 2 shows the handlebar in a folded state, the cross pin 19 of the locking lever 18 is turned out of the opening 20 of the turn plate 15, and the riser 6 can be rotated 90 degrees inwardly about the hinge shaft 16. Since the hinge shaft 16 and the pin 17 There is a certain distance between them. When the riser 6 rotates around the shaft 16, the pin 10 is gradually tightened, and the pin 10 is pulled out of the pin hole 7. At this time, the handlebar shaft 2 can be turned on the sleeve 3. Rotate within 360 degrees.

当车把展开时. 立管 6绕转轴 16向外转动， 转板 15与底座 25 结合， 转动锁紧杆 1 S , 使横销 19旋入横孔 20内， 再转动车把 23， 当车把转轴 2中的销孔 7与销杆 10对准时，销杆 10在弹簧 12的作用 下顶入销孔 7， 车把 23被固定。  When the handlebar is unfolded, the riser 6 rotates outward about the rotating shaft 16, the rotating plate 15 is combined with the base 25, and the locking lever 1 S is rotated so that the transverse pin 19 is screwed into the transverse hole 20, and then the handlebar 23 is rotated. When the pin hole 7 in the rotating shaft 2 is aligned with the pin rod 10, the pin rod 10 is pushed into the pin hole 7 under the action of the spring 12, and the handlebar 23 is fixed.

以上通过一具体实施例对本实用新型进行了详细描述， 但本实用 新型并不局限于此， 在本实用新型的构思范围内可以作出多种变化， 这对本领域技术人员来讲， 是显而易见的。  The present invention has been described in detail through a specific embodiment, but the present invention is not limited thereto, and various changes can be made within the scope of the concept of the present invention, which is obvious to those skilled in the art.
