The invention discloses a trailer connecting device capable of preventing unhooking. The device comprises a fixed base, a movable female seat and a connecting ball head, wherein a fixed female seat isarranged on one end surface of the fixed base; a spherical accommodating groove and a movable female seat groove matched with the movable female seat are formed in the fixed female seat; a connectingball head inlet for placing the connecting ball head into the spherical accommodating groove is formed in the inner wall of the spherical accommodating groove; the movable female seat groove is communicated with the spherical accommodating groove through a connecting ball head inlet, an inlet groove matched with the connecting ball head inlet is formed in the movable female seat, and the movablefemale seat is connected to the fixed female seat in a rotating mode. The area of the connecting ball head wrapped by the spherical accommodating groove formed in the fixed female seat is large, the connecting stability is effectively improved, and the phenomenon that when a vehicle runs on a bumpy road surface, connecting parts are prone to being disengaged from one another is avoided.

    本发明公开了一种防止脱钩的挂车连接装置,包括固定底座、活动母座和连接球头,所述固定底座的一端面上设置有固定母座,所述固定母座上开设有球形容纳槽和与活动母座相配合的活动母座凹槽,所述球形容纳槽的内壁上开设有将连接球头放入球形容纳槽内部的连接球头入口,所述活动母座凹槽与球形容纳槽之间通过连接球头入口相连通,所述活动母座上开设有与连接球头入口相配合的入口凹槽,所述活动母座转动连接于固定母座上。本发明中连接球头被固定母座上开设的球形容纳槽包裹面积大,有效提高了连接稳定性,避免车辆行驶在坑洼路面时容易出现连接部分相互脱离的现象。
