Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a connecting piece for quick butt joint of construction steel bar, includes connecting cylinder 1, 1 threaded connection of connecting cylinder has twisted steel 2, advances to process through the reinforcing bar top and becomes the screw thread form, through the threaded connection of connecting cylinder 1 with twisted steel 2, makes both tightly fixed together. The inner wall of the connecting cylinder 1 is fixedly provided with a sliding block 3, the sliding block 3 is fixedly connected with a long rod 4, and the sliding block 3 drives the long rod 4 to slide on the connecting cylinder 1. The diapire fixed mounting of connecting cylinder 1 has first sleeve 5, the inner wall of first sleeve 5 and the one end fixed connection of first spring 6, the other end fixed connection of first spring 6 has joint pole 7, and when buckle device 8 relieved spacing, first spring 6 provided a power of popping out first sleeve 5 to joint pole 7. The top of joint pole 7 is the toper form, makes the more firm joint in threaded reinforcement 2 in the top of joint pole 7, makes threaded reinforcement 2 be connected with connecting cylinder 1 and is not appearing not hard up, and the outer wall fixedly connected with buckle device 8 of joint pole 7 breaks away from through buckle device 8's joint, makes joint pole 7 relieve spacingly.
