The invention relates to the related field of semitrailer traction seats, and provides a traction seat locking device which is convenient, safe and light in weight. The device comprises a pull rod, a limiting block, a safety lock, a lever, a thrust spring, a hook lock, inclined iron and an inclined iron pin. The pull rod is connected with the thrust spring and the inclined iron and controls movement of the inclined iron, the hook lock is fixed to the position of the point A and can rotate along with the point A, the point E of the hook lock can collide with the point F of the lever during rotation, and the limiting block is fixed to the side face of the traction base shell and used for fixing the position of the pull rod and preventing the pull rod from sliding. The lever is fixed to the point B and the point C of the inner surface of the traction base shell, and the safety lock, the inclined iron pin and the thrust spring are used for controlling the position of the inclined iron. Through cooperative arrangement of the pull rod, the inclined iron pin, the safety lock and the thrust spring, locking of the traction seat of the semitrailer can be achieved.

    本发明涉及半挂车牵引座相关领域,提供了一种方便、安全、重量小的牵引座锁止装置。其中包括拉杆、限位块、安全锁、杠杆、推力弹簧、钩锁、斜铁和斜铁销。所述拉杆与推力弹簧、斜铁相连接,控制斜铁的移动,钩锁固定在A点位置,且可以随着A点转动,转动时钩锁的E点能够与杠杆的F点发生碰撞,限位块固定在牵引座壳体的侧面用于固定拉杆的位置,防止拉杆发生滑动,杠杆固定在牵引座壳体的内表面B点和C点,安全锁、斜铁销和推力弹簧用于控制斜铁的位置。本发明通过拉杆、斜铁销、安全锁以及推力弹簧的配合设置,能够实现对半挂车牵引座的锁止。
