FASTENING ELEMENT FOR INCREASING FIXING STABILITY

Abstract

The present invention provides a fastening element for increasing fixing stability, the fastening element having a drill part formed at the bottom tip of the lower end of a fixing piece so that a fixing groove can be easily formed by means of the drill part when the fixing groove is formed on a structure, wherein one side of the drill part is formed to be pointed and the other side thereof is formed to be blunt so that the fastening element is easily screw-fastened to the fixing groove of the structure and, simultaneously, can be prevented from being loosened by external vibration and the like. The present invention has a protruding part protruding downward from the lower surface of a flange, so that the protruding part is pressed and fixed to the upper surface of the structure so as to enable the fastening element to be more firmly fixed to the structure. In addition, a polygonal upper flange is formed on the upper surface of the flange, and thus a fastening part or the upper flange of the fixing piece is fastened using a wrench and the like, so that the fastening element can be easily fixed onto the structure.

BEST MODE FOR CARRYING OUT THE INVENTION

[0025] The preferred embodiment of the present invention will be described hereinafter in detail with reference to FIGS. 3 to 7. In FIGS. 3 to 7, elements of performing the same function are denoted by the same reference numerals. In the meantime, in the detailed description and the accompanying drawings, illustration and explanation on the detailed technical construction and operation of elements, which have no direct connection with the technical features of the present invention, will be omitted, and only the technical constructions directly related with the present invention will be briefly illustrated and explained.

[0026] Referring to FIGS. 3 to 7, a fastening element for increasing fixing stability according to a preferred embodiment of the present invention includes a fixture 20, a flange 30 and a drill section 40.

[0027] The fixture 20 is intended to be fixedly fastened to a fixing recess 102 of a structure 100. The fixture 20 includes a fastening part 21, a threaded upper end 22 formed below the fixture (20), and a threaded lower end 23 formed below the upper end 22 so as to be fixedly fastened to the fixing recess 102 of the structure 100. The fastening part is rotated by means of a fastening tool. The fastening tool refers to a tool such as a spanner, a wrench or the like.

[0028] The outer circumferential surface of the fastening part of the fixture 20 is formed in a circular or polygonal shape, and the fastening part 21 has a polygonal shaped recess 211 formed therein to allow any one selected from between the circular-shaped fastening part 21 and the polygonal-shaped fastening part 21 to be rotated by the fastening tool. In other words, the fastening part 21 has a polygonal outer circumferential surface and a polygonal shaped recess 211 formed therein as shown in FIG. 5(a), has a circular outer circumferential surface and a polygonal shaped recess 211 formed therein as shown in FIG. 5(b), and has a polygonal outer circumferential surface with no recess formed therein as shown in FIG. 5(c).

[0029] The fixture 20 includes a cut-out part 24 formed on the lower end 23 thereof in such a manner as to be incised extending from the drill section 40 to the flange 30 at a certain angle. The cut-out part 24 includes a molded sharp edge 241 formed on one side thereof so as to form the fixing recess 102 on the structure 100 and a blunt edge 242 formed on the other side thereof. In other words, the sharp edge 241 is formed on one side of the cut-out part 24 to correspond to a rotational direction of the fastening element 10 so that when the fastening element 10 is rotated, a screw thread is formed on an inner circumferential surface of the fixing recess 102 of the structure 100 and simultaneously the fastening element 10 is easily fixedly fastened to the structure 100. The blunt edge 242 formed on the other side of the cut-out part 24 can prevent the fastening element 10 from being loosened with respect to the rotational direction of the fastening element 10.

[0030] The flange 30 is formed extending radially outwardly from an outer circumferential surface of a connection portion between the upper end 22 and the lower end 23 of the fixture 20. In addition, as shown in FIG. 6, a plurality of protrusions 31 is formed protrudingly downwardly from an underside of the flange 30 and a polygonal upper flange 32 is formed on a top surface of the flange 30. In this case, the upper flange 32 has a diameter smaller than that of the flange 30 and larger than that of the upper end 22 of the fixture 20.

[0031] As described above, only the protrusions may be formed on the underside of the flange 30 or only the upper flange 32 may be formed on the top surface of the flange 30. Alternatively, the protrusions 31 and the upper flange 32 may be formed on the underside and the top surface of the flange 30, respectively.

[0032] The drill section 40 is configured to form the fixing recess 102 on the structure 100 and is formed at a bottom tip of the lower end 23 of the fixture 20.

[0033] As described above, according to the fastening element for increasing fixing stability 10 of the present invention, the drill section 40 is formed at the bottom tip of the lower end 23 of the fixture 20 so that the fixing recess 102 can be easily formed on the structure 100 by the drill section 40, and the cut-out part 24 is formed on the lower end 23 of the fixture 20 in such a manner as to be formed sharp at one side thereof and formed blunt at the other side thereof so that the fastening element 10 can be easily screw-fastened to the fixing recess 102 of the structure 100 and simultaneously can be prevented from being loosened due to external vibration and the like.

[0034] In addition, the protrusion 31 is formed protrudingly downwardly from the underside of the flange 30 so that the protrusion 31 can be pressed against the top surface of the structure 100 to allow the fastening element 10 to be more securely fastened to the structure 100.

[0035] Further, the polygonal upper flange 32 is formed on the top surface of the flange 30 so that the fastening part 21 of the fixture 20 or the upper flange 32 can be tightened by using a wrench or the like to allow the fastening element to be easily fixedly fastened to the structure 100.

[0036] FIG. 7 is a cross-sectional view showing a fastening process of a fastening element for increasing fixing stability according to a preferred embodiment of the present invention.

[0037] Referring to FIG. 7, the position where to fasten the fastening element to the structure 100 is identified, and then the fastening element 100 for increasing fixing stability is placed at the identified position on the structure 10. Thereafter, the fastening part 21 of the fixture 20 or the upper flange 32 (not shown) of the flange is caused to be rotated by using a fastening tool. In this case, the fastening tool may be a spanner or a wrench. When the fastening element 10 is rotated by fastening tool, the drill section 40 is rotated while forming the fixing recess 102 on the structure 100, and a screw tap is formed on an inner circumferential surface of the fixing recess 102 of the structure 100 by the lower end 23 of the fixture 20 to cause the fastening element 10 for increasing fixing stability to be fixedly fastened to the fixing recess 102 of the structure 100. At this time, the protrusions 31 of the flange 30 are pressed against a top surface of the structure 100 while being brought into close contact with the top surface of the structure 100 so that the fastening element 10 is more securely fastened to the structure 100.

[0038] While the fastening element for increasing fixing stability according to a preferred embodiment of the present invention has been described and illustrated in connection with specific exemplary embodiments with reference to the accompanying drawings, it will be readily appreciated by those skilled in the art that it is merely illustrative of the preferred embodiments of the present invention and various modifications and changes can be made thereto within the technical spirit and scope of the present invention.
