Specific embodiments

Extremely shown in Figure 7 as Fig. 1, a kind of inserting fastening type multifunction scaffold, by cross bar 5, vertical rod 6, socket 1, plug 4 and brace 8 form the one or both ends of plug position hand cross bar or brace, socket is fixed in the vertical rod, and axle is provided with swivelling cover 2 in the vertical rod of socket upper end.The intrinsic spacing ring 3 of cover in the vertical rod of swivelling cover upper end, the effect of spacing ring are that retaining is pressed swivelling cover, make swivelling cover only can come back rotation between spacing ring and socket, and can not move up and down along vertical rod.Described swivelling cover is by four conical rebate, 14 upper ends that rotarily open or seal socket in vertical rod.Press required separation distance welding socket in the vertical rod, assembling swivelling cover and welded limiting ring in the cross bar two ends of Len req solder plug, are installed plug at the brace two ends of Len req.

Described socket is made of interior endless tube 15, the outer snap ring 11 of opening, spacing Kato 12, card key 10, conical rebate and protruding block 13, and described protruding block is higher than the outer snap ring upper surface of opening, and protruding block is positioned at a side of the outer snap ring of two adjacent openings upper end.Protruding block is two, and its effect is to cooperate the notch part on the swivelling cover to realize the location of swivelling cover to the unlatching and the sealing of conical rebate.Four opening wild card central spacer distances of separating are positioned at outside the endless tube, and middle wall fuses by card key and interior endless tube outer wall in the every outer snap ring of opening, and spacing Kato is positioned on the endless tube wall at middle part, the outer snap ring lower end of two adjacent openings.Space between interior endless tube outer wall and adjacent two card keys and the adjacent outer snap ring inwall of two openings surrounds the conical rebate that can insert for plug, and conical rebate 14 can be up big and down small, with stable bag card plug.Socket adopts one-step casting to form.

Described swivelling cover by interior ring 20, opening outer shroud 21, connecting key 22, knock piece 23 and notch part 24 is constituted, the protruding block setting of described notch part respective socket upper end, described knock piece be positioned at connecting key corresponding opening external annulus on.The effect of knocking piece is to be beneficial to the rotation swivelling cover.Obviously, the shape of cross section of swivelling cover should be identical with big small size with the projection of shape that socket upper end and protruding block upper surface constitute with big small size.Notch part during work on the swivelling cover cooperates with protruding block on the socket to be realized locking and unblanking.When two protruding block sides touch mutually on two notch part sides on the swivelling cover and the socket, be that opening outer shroud on the swivelling cover and connecting key are when vertically overlapping with outer snap ring of the opening on the respective socket and card key, swivelling cover is opened conical rebate, this moment, plug can inject in the conical rebate by swivelling cover, then pound with a hammer again and knock piece opening outer shroud on the swivelling cover and the outer snap ring of the opening on connecting key and the respective socket and card key are vertically interlaced, swivelling cover seals each conical rebate upper end, the locking plug is finished and is built scaffold in each conical rebate.Otherwise can take from plug in each conical rebate, finish the dismounting scaffold.
