Abstract
The utility model relates to a double-line fine-thread drywall screw which is composed of a screw head (1), a screw body (2) and a screw tail (3). The screw head (1) is in a trumpet shape, the end face of the top of the screw head (1) is circular, a stress groove (4) is formed in the center of the end face, threads (5) are arranged on the screw body (2), and the screw tail (3) is sharp. The double-line fine-thread drywall screw is simple in structure and reasonable in design, tapping speed is improved, and meanwhile the double-line fine-thread drywall screw is safe and convenient to use, and has good practical and promotional value.
Description
Technical field
The utility model relates to a kind of drywall screw, especially a kind of two-wire closely-pitched drywall screw.
Background technique
Drywall screw, claims again wallboard nail, is generally used for being connected of gypsum board and rough ground and gypsum board and Lightgage Steel Joist.A kind of as fastening piece, its technical requirements is relatively high, and it can be screwed into keel or steel plate fast not making under the condition in pre-hole, plays good connection and fixation.
At present, because production technology problem, a lot of manufacturer production drywall screw head is not out to justify very much, and some is even slightly square, can not mate with gypsum board completely after drywall screw is screwed into.The tip of some drywall screw is full not, drags silk, cracking phenomena, while causing using, bores not enter, and directly affects its use.The cross recess of some drywall screw is partial to ailhead end face centre position, and screw tail is eccentric, when electric tool is screwed into, occurs rocking, and can not well connect sheet material, makes the easy landing of drywall screw, affects it and normally uses.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, has designed a kind of simple in structurely, attacks speed fast, two-wire closely-pitched drywall screw easy to install.
The utility model solves its technical problem and takes following technological scheme to realize:
A two-wire closely-pitched drywall screw, is comprised of ailhead, rivet nut, nail tail, it is characterized in that: described ailhead is horn-like, and ailhead top end face is rounded, and the center position of end face is provided with stressed groove, and rivet nut is provided with screw thread, and nail tail is pointed.
And described stressed groove is cross grooved.
And, described screw thread by two independently helix group go out.
Advantage of the present utility model and good effect are:
1, the utility model adopts the design of two-wire closely-pitched, and between screw thread, tooth is apart from little, and screw thread is fine and closely woven, has played self tapping from the effect of boring, and can be screwed into fast keel or steel plate not making under the condition in pre-hole, plays good connection and fixation; Necessarily shoot under the prerequisite of speed having guaranteed, be more suitable for the installation of metal joist.
2, the utility model is simple in structure, reasonable in design, improves and to attack fast time, and safe handling is convenient, has good practical and popularizing value.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is plan view of the present utility model;
In figure: ailhead 1, rivet nut 2, nail tail 3, stressed groove 4, screw thread 5.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
As shown in the figure, a kind of two-wire closely-pitched drywall screw described in the utility model, is comprised of ailhead 1, rivet nut 2, nail tail 3.In use, select special electric screw gun to install and use.Its ailhead 1 is inserted in eclectic screw gun, the stressed groove 4 phase interlocks of eclectic screw gun crosshead and ailhead 1 top end face center position, eclectic screw gun is aimed to gypsum board face, drive two-wire closely-pitched drywall screw to rotate, do not beating under the condition of pre-manufactured hole, the two-wire closely-pitched drywall screw of rotation is screwed into keel or steel plate fast, plays good connection and fixation.
It is emphasized that; embodiment described in the utility model is illustrative; rather than determinate; therefore the utility model is not limited to the embodiment described in embodiment; every other mode of executions that drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope that the utility model is protected equally.
Claims (3)
1. a two-wire closely-pitched drywall screw, by ailhead (1), rivet nut (2), nail tail (3), formed, it is characterized in that: described ailhead (1) is horn-like, ailhead (1) top end face is rounded, the center position of end face is provided with stressed groove (4), rivet nut (2) is provided with screw thread (5), and nail tail (3) is pointed.
2. two-wire closely-pitched drywall screw according to claim 1, is characterized in that: described stressed groove (4) is cross grooved.
3. two-wire closely-pitched drywall screw according to claim 1, is characterized in that: described screw thread (5) by two independently helix group go out.
