The invention discloses a device for connecting a trailer load with a trailer hook ball head, which comprises a base connected to the trailer load; the clamping mechanism is used for clamping the tow hook ball head, the clamping mechanism comprises two clamping components, and at least one clamping component is pivoted to the base; clamping curved surfaces matched with the surface of the tow hook ball head are arranged on the opposite inner walls of the two clamping components, and when the two clamping components are closed, the clamping curved surfaces jointly form an openable space used for receiving the tow hook ball head; a concave avoiding area is arranged in the clamping curved surface, and a gap is formed between the concave avoiding area and the outline of the corresponding tow hook ball head. The tow hook ball head connector has the advantage that the problem that a ball head of an existing tow hook ball head connector is prone to shaking in the dragging process is solved. The transverse swing resistance is remarkably improved, the connection between the connecting ball head and the connector body is more stable, the connecting ball head and the connector body are not prone to shaking in the dragging process, local stress concentration caused by rigid constraint is avoided, and the fracture risk is reduced.

    本发明公开了用于拖车负载与拖车钩球头连接的装置,包括:基座,其连接到拖车负载;以及,夹持机构,其用于夹持拖车钩球头,该夹持机构包括两个夹持构件,至少一个夹持构件枢接到基座;两个夹持构件相对的内壁上均设有与拖车钩球头表面适配的夹持曲面,当两个夹持构件闭合时,夹持曲面共同形成用于接收拖车钩球头的可开合空间;夹持曲面内设有凹陷避让区,凹陷避让区与对应的拖车钩球头轮廓之间形成间隙。本发明的优点是:解决目前拖钩球头连接器在拖拽过程中容易出现球头晃动的问题。显著提升抗横向摆动的能力,让连接球头和连接器本体连接更加稳定,不易在拖拽过程中出现晃动,避免因刚性约束导致的局部应力集中,降低断裂风险。
