Drawings

Fig. 1 is a schematic view of the three-dimensional structure of the present invention.

In the figure: 1. a rotating base; 11. a groove; 12. a through hole; 2. a gland; 21. a U-shaped opening; 3. a fastening unit; 31. a bolt; 32. a nut; 4. a pin shaft; 5. and (4) an anti-drop baffle.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings.

Referring to the attached drawings, a scaffold rotating fastener comprises two fastener units, each fastener unit comprises a rotating seat 1, a gland 2 and a fastening unit 3, the inner side surfaces of the rotating seat 1 and the gland 2, which are contacted with a clamped scaffold steel pipe, are of circular arc structures, the two rotating seats 1 are hinged through a pin shaft 4, so that the two fastener units can rotate at any angle around the pin shaft 4 to realize connection of the two scaffold steel pipes at different angles, one end of each rotating seat 1 is hinged with one end of the gland 2, the bottom of the other end of each rotating seat 1 is provided with a groove 11, the side wall of each groove 11 is provided with a through hole 12, the other end of each gland 2 is provided with a U-shaped opening 21, each fastening unit 3 comprises a bolt 31 and a nut 32, each bolt 31 is T-shaped, the T-shaped head of each bolt 31 is arranged in the corresponding groove 11 in a hinged mode, the threaded end of each bolt 31 penetrates through the through hole 12 and can swing in the through hole 12 at a certain angle, the nut 32 is screwed on the bolt 31, the anti-falling baffle 5 is integrally welded at the top end of the threaded end of the bolt 31, and the diameter of the anti-falling baffle 5 is larger than that of the bolt 31 and used for preventing the nut 32 from falling off.

During installation, a scaffold steel pipe is placed into one of the rotary seats 1, the gland 2 hinged to the rotary seat is rotated, the scaffold steel pipe is pressed, the bolt 31 is rotated to enable the bolt 31 to be embedded into the U-shaped opening 21, then the nut 32 is screwed tightly, the rotary seat 1 and the gland 2 are locked tightly to finish fastening of the steel pipe, then the other fastener unit is rotated to a required angle according to the installation requirement of the other steel pipe, the installation process is repeated, and therefore the erection work of the two scaffold steel pipes according to a certain angle is finished; when the steel pipe is disassembled, the nut 32 is unscrewed, the fastening of the gland 2 and the rotating seat 1 to the steel pipe is released, the anti-falling baffle 5 at the top end of the threaded end of the bolt 31 can prevent the nut 32 from falling, the worries of operators are relieved, and the cost is saved.
