Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-4, a steel structure self-adaptive rapid connecting piece comprises a loop bar 1, a screw 2 is connected with an inner cavity of the loop bar 1 in a threaded manner, a hexagonal groove 3 is formed in the upper end of the screw 2, a base 4 is arranged at the lower end of the screw 2, the diameter of the base 4 is smaller than that of the loop bar 1, the loop bar 1 is divided into a thread section 5 and a polished rod section 6 from top to bottom, a nut 7 and a gasket 8 are sequentially arranged from top to bottom on the upper portion of the outer side of the thread section 5, a conical sleeve 9 is sleeved on the lower portion of the outer side of the polished rod section 6, a T-shaped chute 10 is uniformly arranged on the outer side of the conical sleeve 9, a sleeve 11 is sleeved on the outer side of the conical sleeve 9, a retaining sleeve 12 is fixedly arranged at the upper end of the sleeve 11, the retaining sleeve 12 is positioned below the gasket 8, a through groove 13 corresponding to the T-shaped chute 10 is, the bolt is fixed through the sliding fit between the T-shaped sliding groove 10 and the T-shaped sliding block 15, and meanwhile, the bolt is detached and ejected through the screw rod 2.
The lower extreme of sleeve pipe 11 is fixed and is provided with taper uide bushing 16, and the lower extreme internal diameter of uide bushing 16 is the same with loop bar 1 external diameter, and the setting of loop bar 1 lower extreme outside is the slope spigot surface, makes sleeve pipe 11 be convenient for insert the mounting hole through uide bushing 16 to make the bolt be convenient for install.
