The invention relates to the technical field of ring control pipeline low-pressure ventilation, in particular to a large-flow wide-angle air conditioning nozzle which comprises a ball seat, the ball seat is of a structure with two open ends, an exhaust pipe is arranged on the inner wall of the ball seat in a sleeving mode and rotationally connected with the ball seat, and the bottom end of the exhaust pipe extends out of the bottom end of the ball seat to serve as an exhaust outlet. A valve piece is hinged to the inner wall of the exhaust pipe, a deflector rod is fixedly connected to the top of the valve piece, a baffle ring is further arranged above the valve piece and fixedly connected with the inner wall of the ball seat, a limiting fork matched with the deflector rod is arranged on the inner side wall of the baffle ring, and when the exhaust pipe is rotated, the valve piece turns over the exhaust pipe to be conducted under the action of the deflector rod and the limiting fork. When the exhaust pipe is rotated, the valve piece is turned over under the action of the shifting rod and the limiting fork, when the exhaust pipe is rotated by a half circle, the exhaust pipe can be completely opened, the opening time is greatly shortened, and the problem that in the prior art, a spiral lifting structure rotary knob is adopted, and the opening time is too long is solved.
本发明涉及环控管路低压通风技术领域,具体涉及一种大流量宽角度空气调节喷嘴,包括球座,所述球座为两端开口结构,球座内壁套装有排风管,排风管与球座转动连接,排风管底端延伸至球座底端外部作为排风口,所述排风管内壁铰接有活门片,活门片顶部固定连接有拨杆,所述活门片上方还设有挡环,挡环与球座内壁固定连接,挡环内侧壁设有与拨杆相配合的限动叉,转动排风管时,活门片在拨杆和限动叉的作用下实现翻转排风管导通;本发明当转动排风管时,活门片在拨杆和限动叉的作用下实现翻转,当转动排风管半圈时,排风管即可完全打开,开启时间大大缩短,此种方式解决了现有技术中采用螺旋式升降结构旋钮全部开启时间过长的问题。
