AI Technical Summary

Technical Problem

The existing trailer towing seat is prone to slippage or displacement due to vibration and impact loads after adjustment, resulting in insufficient height positioning stability.

Method used

The towing bracket traction seat installation structure with anti-slip positioning is adopted. Multiple positioning holes are set on both sides of the fixed frame, and locking pins are set on both sides of the mounting seat. The linkage turntable and the locking pins work together to realize the synchronous operation of the locking pins on both sides. Combined with the design of guide groove and return spring, the mounting seat is stably positioned after adjustment.

Benefits of technology

It improves the height positioning stability of the trailer towing seat during agricultural towing, reduces the risk of slippage or deviation caused by vibration and impact, and is easy to operate with high consistency.

Abstract

本发明涉及农用牵引连接结构的领域,公开了带防滑定位的拖挂架牵引座安装结构,包括固定架、安装座、牵引座、锁止销、联动转盘和操作把手,固定架两侧沿高度方向设有多个定位孔,安装座可上下移动地设于固定架,牵引座设于安装座,两个锁止销分别设于安装座两侧并用于插入对应定位孔内;联动转盘转动设于安装座并与两个锁止销联动配合,操作把手与联动转盘连接。调节高度时,操作把手带动联动转盘转动,使两个锁止销同步脱离定位孔,安装座能够相对固定架上下移动;调节到位后,两个锁止销插入对应定位孔内,实现牵引座的高度锁止。本发明能够提高牵引座高度调节后的防滑定位稳定性。
