The invention provides a self-positioning structure for a vulcanized rubber pipe clamp of an air filter. The self-positioning structure comprises a hose and a clamp, wherein an annular positioning groove is formed in the end of the hose; a positioning column is arranged on the annular positioning groove, and the diameter of the outer end of the positioning column is greater than that of a rod part; the clamp comprises a clamp band and an end screw part; a positioning long hole in the circumferential direction is formed in the position, close to the end screw part, of the clamp band, the widthof the positioning long hole is smaller than the diameter of the outer end of the positioning column, and the width of the rod part of the positioning column is matched with the width of the positioning long hole; a clamping end is arranged at the end of the positioning long hole, and the inner diameter of the clamping end is greater than the diameter of the outer end of the positioning column; limiting blocks are arranged on the annular positioning groove; the end screw part is in a limited state in the circumferential direction after being clamped into the limiting blocks; and a screw on theend screw part is screwed up and the clamp band is tensioned to fixedly connect the hose to a rigid pipe. According to the self-positioning structure, the fixing of the mounting position of a bolt head of the clamp and the consistency of the orientation of the bolt head are ensured, the design clearance and the production assembly property are met, and rapid assembly is realized.

    本发明提供了一种空滤器硫化橡胶管道卡箍自定位结构,包括软管和卡箍,软管端头处开设有环形定位槽,环形定位槽上设置有定位柱,定位柱外端头直径大于杆部直径,卡箍包括卡箍带和端头螺杆部,卡箍带靠近端头螺杆部设置有沿圆周方向的定位长孔,定位长孔的宽度小于定位柱外端头直径,定位柱杆部的宽度与定位长孔的宽度相适配,定位长孔端头处设置有卡入端,卡入端内径大于定位柱外端头直径,环形定位槽上设置有限位块,端头螺杆部卡入限位块后在圆周方向处于限位状态,拧紧端头螺杆部上的螺杆拉紧卡箍带将软管固定连接在硬管上。本发明保证了卡箍螺栓头安装位置的固定和螺栓头朝向的一致性,满足设计间隙以及生产装配性,实现快速装配。
