Self-locking double-sleeve straight thread sleeve connecting structure

BAI JIANPING

The invention discloses a self-locking double-sleeve straight thread sleeve connecting structure which comprises a straight thread sleeve, a double-shoulder straight thread screw sleeve, a single-shoulder straight thread screw sleeve and a lock nut. A first reinforcing steel bar component with a first reinforcing steel bar screw head is connected with one end of the straight thread sleeve through the double-shoulder straight thread screw sleeve; a second reinforcing steel bar component with a second reinforcing steel bar head is connected with the other end of the straight thread sleeve through a single-shoulder straight thread sleeve, and the single-shoulder straight thread sleeve is locked in the straight thread sleeve through a lock nut. According to the invention, the first reinforcing steel bar component part and the second reinforcing steel bar component part are stably connected in the straight thread sleeve through the double-shoulder straight thread screw sleeve, the single-shoulder straight thread screw sleeve and the lock nut by utilizing the butting and locking performance of the end face of the straight thread screw head, that is, the thread self-locking connection of the reinforcing steel bar connecting piece is achieved by adopting a split combination mode, the construction is simple and convenient, and the construction efficiency is improved. Quality detection is convenient and visual, and popularization and use are facilitated.

本发明公开了一种自锁双套直螺纹套筒连接结构，包括直螺纹套筒、双肩直螺纹丝套、单肩直螺纹丝套和锁母，带有第一钢筋丝头的第一钢筋部品部件通过双肩直螺纹丝套与直螺纹套筒一端连接，带有第二钢筋丝头的第二钢筋部品部件通过单肩直螺纹丝套与直螺纹套筒另一端连接，且单肩直螺纹丝套通过锁母锁紧在直螺纹套筒内。本发明利用直螺纹丝头端面对顶锁紧性能，通过双肩直螺纹丝套、单肩直螺纹丝套和锁母，使得第一钢筋部品部件和第二钢筋部品部件稳固地连接在直螺纹套筒内，即采用分体组合方式达到钢筋连接件螺纹自锁的连接，施工简单便捷，质量检测方便直观，便于推广使用。
