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. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-3, the utility model provides a technical solution: the utility model provides a construction scaffolding's screw, including bolt body 1, bolt body 1 comprises double-screw bolt 101 and head 102 two parts, and double-screw bolt 101 is the external screw thread cylinder, double-screw bolt 101 surface threaded connection has nut 2, the one end that head 102 was kept away from to double-screw bolt 101 is provided with screw hole 3, screw hole 3 and 4 threaded connection of screw, the hexagonal head bottom fixedly connected with spring 5 of screw 4, spring 5 keeps away from the one end fixedly connected with gasket 6 of screw 4, one side that spring 5 was kept away from to gasket 6 contacts with one side that head 102 was kept away from to nut 2, gasket 6 and the equal activity of spring 5 cup joint are on the surface of double-screw bolt 101, install nut 2 when using after double-screw bolt 101 surface locking, cup joint spring 5 and gasket 6 to double-screw bolt 101 surface and screw hole 3 are inserted to screw 4 again, screw 4.

As a technical optimization scheme of the utility model, head 102, hexagonal head and nut 2's shape is the same, screw up or when becoming flexible use the same type spanner can, simplify instrument quantity, improve the portability.

As a technical optimization scheme, gasket 6 is the ring form, the diameter of gasket 6's hole is greater than the diameter of double-screw bolt 101, when screw 4 is installed to threaded hole 3, screw 4 precession screw hole 3 in-process spring 5 and gasket 6 all synchronous revolution, make spring 5 only receive the pressure of vertical direction and compress when screw 4 screws up, no torsional force, can not reset and the counter-rotation is not hard up because of spring 5 when can guaranteeing screw 4 screws up, spring 5's elasticity is in vertical direction, can increase the extrusion force of screw thread between screw 4 and the screw hole 3, increase the extrusion force of screw thread between nut 2 and the double-screw bolt 101 simultaneously, thereby improve threaded connection's fastness.

As the utility model discloses a technical optimization scheme, the axis of bolt body 1 and the coincidence of the axis of screw 4, bolt body 1 and the mutual locking other side of screw 4 can guarantee holistic stability.

To sum up can, the utility model discloses a set up bolt body 1, screw hole 3, screw 4, spring 5 and gasket 6, solved and can lead to screw and nut cooperation to produce not hard up in the long-term use of construction scaffolding, not hard up can arouse the phenomenon that construction scaffolding is connected insecure and collapses, consequently has the problem of potential safety hazard.
