The quick locking tractor comprises a cast steel shell, a ball cavity and a mounting groove which are communicated with each other are formed in the two sides of the bottom end of the cast steel shell respectively, and an adjustable adjusting bolt is arranged in the ball cavity. When the locking assembly is rotated downwards, under the action of the limiting structure, the bottom sleeve gasket ring makes contact with the inner top wall of the cast steel shell, the compression spring has downward force, the clamping spring drives the pull rod to move downwards, the lifting inner block makes contact with the adjusting bolt, the ball head is effectively locked, and under the action of the compression spring, the clamping spring and the bottom sleeve gasket ring, the locking assembly is not prone to loosening; the tractor is simple in structure, convenient to operate and capable of achieving quick locking of equipment, the overall length is quite short due to the internal structural layout of the tractor, and the distance between the ball head and the pull rod on the rear portion is short. In this way, the moment borne by the pull rod is small when the pull rod is used. Due to the characteristic, the tractor can be used for a larger load and can be mounted on a large trailer, and the application range of the tractor is widened.

    本发明实施例公开了一种拖车用的快速锁紧牵引器,包括铸钢壳体,所述铸钢壳体的底端两侧分别开设有相互连通的球腔和安装槽,所述球腔的内部设置有可调节的调节螺栓。向下旋转锁紧组件,在限位结构的作用下,底套垫片环和铸钢壳体的内顶壁接触,压簧有个向下的力,使得卡簧带动拉杆向下移动,升级内块和调节螺栓接触,对球头进行有效锁紧,在压簧、卡簧和底套垫片环的作用下,锁紧组件不易松动,且操作方便,能够实现设备的快速锁紧,该牵引器内部的结构布局使得整体的长度相当短,球头离后部的拉杆距离短。如此,使用的时候拉杆上的承受的力矩会比较小。这个特点也帮助牵引器能够用于更大的负载,能安装于大型拖车上,提高了牵引器的适用范围。
