The nut of said structure, locking wheel inserts in the mounting plate hole clipping, blocks and can not advance until limited plate; Mounting hole on another section bar is aimed at the tapped hole on the limiting board, and inserting bolt, bolt screws in the tapped hole of nut; When rotating, bolt drives the nut rotation; In the hole clipping side is provided with on the mounting plate the inserted part incision guiding groove, the nut rotation is placed restrictions on structure in the chocking construction on the inserted part and the guiding groove and is contacted; Nut is no longer with the bolt rotation, and last locking block and bolt are locked simultaneously; Nut is fastened in the hole clipping of mounting plate; Nut contacts with the mounting plate face; Nut has enough rigidity and intensity is born bigger shearing force, and should design hole clipping on lower installation board not fragile, can satisfy mounting plate with the secondary of another section bar and repeatedly assemble and be connected.
The utility model further is set to: described locking wheel body side face is provided with two locking blocks that are provided with along locking wheel body radial symmetric; Described annular guiding groove has two, and corresponding hole clipping sidewall is provided with and two two inserted parts that annular guiding groove is suitable.
Said structure is provided with, and symmetrically arranged two locking blocks make nut be connected the back stress balance with mounting plate, and guiding groove and inserted part clamping are reliable, and locking block is provided with conveniently.
The utility model further is set to: the described structure stops that exceeds of placing restrictions on; Place restrictions on piece and be located at the guiding groove end; This end be guiding groove along the end on the nut sense of rotation, the described chocking construction stop surface that to be the inserted part form along the end of nut screw-in direction and hole clipping sidewall.
Through adopting technique scheme, can be through placing restrictions on piece effectively with the unidirectional stop of swivel nut, make guiding groove fully with after cabinet cooperates, nut no longer rotates with bolt, finally reaches the connection of screwing of bolts and nuts.
The utility model further is set to: the described piece outer surface of placing restrictions on is the cambered surface setting, and said stop surface is and places restrictions on the suitable inner concave arc surface in piece surface.
Employing said structure design is placed restrictions on outer surface and the stop surface of piece and can be fitted fully, and the minimizing bolt causes damage at the effect lower limit stops and the stop surface of rotational shear power when screwing.
Below in conjunction with accompanying drawing the utility model is further described.
