Abstract

The utility model discloses a threaded nail which is composed of a nail head, a nail body and protruded tooth-shaped threads arranged on the side surface of the nail body, wherein the tooth-shaped threads are five line threads, the spiral line of the five line threads and the axis form a 30-degree angle, the distance of the adjacent threads is 2mm, and the depth of the thread is 0.5mm. In the utility model, the five line tooth-shaped threads are arranged on the threaded nail body, so as to lead the threaded nail to be stressed easily and to be threaded into a wall body or a wood plate easily; furthermore, as the spiral line of the five line threads and the axis form the 30-degree angle, the nail body is hard to be pulled out. Compared with the prior art, the threaded nail has the advantages of simple structure, convenient installation and wide application and the like.

Description

Drive screw

Technical field:

The utility model belongs to link, the drive screw of fixedly connected usefulness in particularly a kind of home decoration.

Background technique:

At present in home decoration, often need to use iron nail to fixedly mount, its mainly be with iron nail by knocking, it is fixed in body of wall or the plank, reach the effect that is connected and fixed.This iron nail is given a shock easily to produce and becomes flexible, and especially when being subjected to axial tension, pulls out from body of wall or plank easily.

Summary of the invention:

Iron nail is subjected to the problem that axial tension is pulled out when mounted easily in the prior art from body of wall or plank in order to overcome, and the purpose of this utility model is to provide a kind of drive screw.

For achieving the above object, the utility model is mainly by the following technical solutions:

A kind of drive screw, by the head of a nail (1), nail body (2) be arranged at protruding dentation screw thread (3) formation of nail body (2) side, wherein said dentation screw thread (3) is five line screw threads, the helix of this five lines screw thread becomes 30 ° of angles with axis, and the spacing between the adjacent thread is 2mm, and the degree of depth of screw thread is 0.5mm.

The described head of a nail (1) surface is the plane.

The utility model is provided with five line dentation screw threads by following closely on the body at screw, thereby makes this drive screw stressed easily, can be easy to enter in body of wall or the plank, in addition because the helix of five line screw threads becomes 30 ° of angles with axis, thereby makes screw be not easy to pull out.Compared with prior art, the utlity model has simple in structure, easy for installation, advantage such as be widely used.

Description of drawings:

Fig. 1 is the utility model stereogram.

Fig. 2 is the utility model sectional view.

Fig. 3 is user mode figure of the present utility model.

Identifier declaration among the figure: the head of a nail 1, nail body 2, screw thread 3, ailhead 4, body of wall 5.

Embodiment:

For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.

See also Fig. 1, shown in Figure 2, the utility model provides a kind of drive screw, this drive screw mainly is made of the head of a nail 1, nail body 2 and screw thread 3, and wherein screw thread 3 is five line dentation screw threads, and it is arranged at nail body 2 sides, be convex, these screw thread 3 upper ends are the head of a nail 1, and the head of a nail 1 upper surface is a plane, by beaing drive screw are entered with convenient, be provided with the light body of 4mm between the screw thread 3 and the head of a nail 1, screw thread 3 lower ends are ailhead 4.

The helix of wherein above-mentioned this screw thread 3 becomes 30 ° of angles with the axis of drive screw, and the spacing between the adjacent thread is 2mm, and the degree of depth of screw thread is 0.5mm.

The related drive screw of the utility model includes two kinds of specifications: a kind of is the long 65mm that is, diameter is the drive screw of 3mm; A kind of is the long 50mm that is, diameter is the drive screw of 2mm.

As shown in Figure 3, Fig. 3 is the utility model user mode figure.At first drive screw is fixed in body of wall 5 places, beats the head of a nail of drive screw then by iron hammer, it can be hammered into, this drive screw can directly hammer in the body of wall 5, need not to rotate with instrument.

The screw thread that is provided with on the utility model nail body is five line dentation screw threads, and the spacing between the adjacent thread is 2mm, and the degree of depth of screw thread is 0.5mm, thereby can effectively increase frictional force, makes the attachment difficult drop-off.

More than a kind of drive screw provided by the utility model is described in detail, used specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.

Claims (2)

1. drive screw, by the head of a nail (1), nail body (2) be arranged at protruding dentation screw thread (3) formation of nail body (2) side, it is characterized in that described dentation screw thread (3) is five line screw threads, the helix of this five lines screw thread becomes 30 ° of angles with axis, and the spacing between the adjacent thread is 2mm, and the degree of depth of screw thread is 0.5mm.

2. drive screw according to claim 1 is characterized in that the described head of a nail (1) surface is the plane.
