Abstract

The utility model relates to a quick nut locking device. The inner ring of a perforation of an assembly object is sheathed with a soft lining whose bottom surface forms a locking hole, and a screw can be screwed in the locking hole. A shim is sheathed beneath a nail head of the screw nail. In the assembly process, the screw nail which is sheathed with the shim is screwed in locking hole of the bottom surface of the soft lining and then is locked in the structure body. When the screw nail is locked and abutted on the top surface of the assembly object, and simultaneously, the bottom surface of the lining floats upwards through the rotation action of the screw nail to be extruded and deformed, and the screw thread of the screw nail is oppressed and can not be rotated continuously. So the screw nail and the assembly object are locked, and a buffer action is formed.

Therefore, the purpose of this utility model is to provide a kind of quick nut fastening structure, form the soft lining that a lockhole can make screw screw in the sheathed bottom surface of the perforation inner ring of loading object, be arranged with a pad in the ailhead below of screw in addition, the lockhole that its screw system that is with pad screws in the soft lining of loading object inner ring in advance in assembly process is locked in the locking body again, when its screw is locked when being resisted against the state of loading object end face, its soft lining bottom surface meeting upwards buoyance lift extrusion-deformation because of the turn of screw simultaneously, and the thread of screw imposed a urgent power, go deep in the structure because the torsion that is applied is excessive to force screw, avoid causing the debentition phenomenon of structure destruction even; And make its screw stop to continue to go deep in the structure by the packing effect of lining and pad, further reach the height gap that to adjust automatically between loading object and structure, because all multifactor in the course of working, the height that causes each locking point can't all be maintained at same level height and the height difference that forms to cooperate its loading object itself.

A time purpose of quick nut fastening structure of the present utility model is in the fit mode that directly is placed on loading object perforation inner ring by its lining, can directly make the perforation of loading object and the quick involutory location of lockhole of lining.

A kind of quick nut fastening structure is characterized in that main structure includes:

One lining, this lining are the soft structures of a hollow, and its bottom center position is formed with a lockhole, in addition lockhole are made ring formation tool helical in it in the mode of cutting sth. askew, and screw screws in the lockhole of lining;

One is arranged with the screw of pad, this screw can be general mechanical screw or wood screw, the tip of screw extends to form the guide portion of an elongate, and this pad that is sheathed on screw ailhead below can be general tack pad again, or the bottom surface outer shroud is formed with the pad of saw tooth structure.
