【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of locking drywall screw, is equipped with anti-
The rinforcement bar structure of pine, good fixing effect, security risk caused by avoiding connection not close.
To achieve the above object, the utility model proposes a kind of locking drywall screw, including the head of a nail, nail body, ailhead, reinforcing
Muscle, the head of a nail lower end connected nail body, the nail body lower end are equipped with ailhead, and the head of a nail, nail body, ailhead are an integral structure,
Screw thread is evenly provided with the nail, the bottom of the head of a nail is equipped with transition arc, and the bottom of the transition arc is equably
Equipped with several rinforcement bars.
Preferably, the head of a nail top end surface is rounded.
Preferably, the tapered structure of ailhead.
Preferably, the center of the head of a nail top end surface is equipped with stress groove, the stress groove can be that linear type is recessed
Slot or cross groove.
Preferably, the rinforcement bar is extended to the front position of nail body by the bottom end of transition arc, the rinforcement bar
Setting direction is parallel with nail body direction, and the side of the rinforcement bar is trapezium structure wide at the top and narrow at the bottom.
Preferably, the outside of the rinforcement bar is equipped with the little groove of several levels.
The beneficial effects of the utility model：A kind of locking drywall screw of the utility model, the bottom of the head of a nail are equipped with transition arc,
The bottom of transition arc is evenly provided with several rinforcement bars, and after screw is screwed into, rinforcement bar can play clamping fixed plate, prevent
The effect of screw loosening；The side of rinforcement bar is trapezium structure wide at the top and narrow at the bottom, and the outside of rinforcement bar is equipped with the small of several levels
Groove can further strengthen anti-loosening ability.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
【Description of the drawings】
Fig. 1 is a kind of structure diagram of locking drywall screw of the utility model.
In figure：The 1- heads of a nail, 2- nail body, 3- ailheads, 4- rinforcement bars, 11- transition arcs, 12- stress groove, 21- screw threads,
