JP3069717U - Driving screw - Google Patents

Abstract

(57) [Summary] [Problem] The present invention can be used as a screw by loosening or tightening even after driving by inserting grooves of various tightening tools into a driving tack. In addition, since it is used by being driven, the tightening time can be greatly reduced as compared with the conventional screw. The present invention provides a groove in a non-grooved head of 1-A so that various kinds of tightening tools can be used as in 2-A, and a 2-C screw so that a screw can be tightened by a single driving. The length of the distal end guide portion is made longer and the length of the screw is made constant as shown in 6-B, so that it can be used as a screw, and the tightening time can be greatly reduced.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a screw which can be tightened by driving at the time of connection, and thereafter can be loosened or tightened with various tightening tools.

[0002]

[Prior art]

 The conventional Parker studs were used only by driving them in like nails, so the head had no groove or other structure.

[0003]

[Problems to be solved by the invention]

 The solution has been improved so that it can be used not only as a tack but also as a screw, and the tightening time has been greatly reduced compared to conventional screws.

[0004]

[Means for Solving the Problems]

 In the present invention, various grooves are easily inserted into the head so that various fastening tools can be used so that it can be used not only as tacks but also as screws, and the tip gadging part is lengthened so that the screw stands vertically. In addition, the length of the screw part is also fixed so that it can be tightened with a single driving, so that the tightening time is greatly reduced and the screw can be used as a screw.

[0005]

[Embodiment of the invention]

 Grooves are made in the head so that various tightening tools can be used, and the outside diameter of the head is enlarged so that the grooves are not broken during driving, the force at the time of driving is distributed in a nearly flat shape, and the screw bends in. The length of the tip guide was increased so that it would not stand out. In addition, the length of the threaded part was also set to a certain length so that it could be tightened with a single driving.

[0006]

【Example】

 Hereinafter, embodiments will be described with reference to the accompanying drawings. Since there is no groove in the head of 1-A in FIG. 1, it cannot be loosened or tightened after tightening. Further, since the guide portion 1-B is short, there is a risk that the guide portion may be bent as shown in FIG. Therefore, in order to be able to use the conventional driving tack as a screw, a groove that can be tightened with various tools of 2-A as shown in Fig. 2 is provided, and the head diameter is increased so that the groove is not broken. By tightening the length of the guide portion as shown in FIG. 4 as 2-C so that the screw stands vertically when tightening as shown in FIG. 4, the screw can be tightened as shown in FIG.

If the tightening length of the screw is long, open the bottom of the neck as shown in 6-A of FIG. 6 and determine the length of the 6-B screw to a length that can be driven in once, thereby shortening the tightening time. Shortening is achieved, and the tightening shown in FIG. 7 is completed.

[0008]

[Effect of the invention]

 As described above, the driving screw of the present invention can be tightened by driving, and can be loosened or repeatedly tightened with various types of tightening tools, greatly reducing the time required for screw tightening .

Claims (1)

[Utility model registration claims] The present invention relates to a driving screw which can be loosened or tightened by a groove formed by inserting a groove of various kinds of tightening tools into a head so that it can be tightened or loosened with a driving tack. Also, in order to make it easier to drive, lengthen the tip guide part so that the screw can be set up vertically, and determine the length of the screw part to a fixed length so that tightening can be done by one driving. By increasing the outer diameter of the head and making it almost flat so that the grooves are not broken, the pressure is dispersed and the various grooves are not broken.
It is a driving screw that can be tightened in a number of times so that the tightening time can be significantly reduced compared to conventional screws.
