Description
본 고안은 고무머리볼트에 관한 것으로, 보다 상세하게는 고무머리부와 금속재의 축부 사이의 마찰면적을 증대시켜, 금속재의 축부와 고무머리부의 결합력을 강화시킨 고무머리볼트에 관한 것이다.The present invention relates to a rubber head bolt, and more particularly to a rubber head bolt to increase the friction area between the rubber head and the metal shaft portion, thereby strengthening the bonding force of the metal shaft portion and the rubber head portion.
일반적으로, 고무머리볼트는 볼트의 머리부분에 고무를 성형하여 이에 접촉하는 상대물을 보호하도록 한 것이다.In general, the rubber head bolt is to form a rubber on the head of the bolt to protect the opponent in contact with it.
이러한 종래의 고무머리볼트를 첨부도면을 참조하여 설명하면 다음과 같다.The conventional rubber head bolt will be described with reference to the accompanying drawings.
첨부도면 도 1은 종래의 고무머리볼트를 도시한 도면이다.1 is a view showing a conventional rubber head bolt.
도시된 바와 같이, 고무머리볼트(2)는 그 외주면에 나사산(22)이 형성되고 금속재로 이루어진 원기둥 형상의 축부(20)와, 이 축부(20)의 일단면에 부착된 고무머리부(10)로 이루어진다.As shown, the rubber head bolt 2 has a cylindrical shaft portion 20 formed on its outer circumferential surface and made of a metallic material, and a rubber head portion 10 attached to one end surface of the shaft portion 20. )
이러한 고무머리볼트(2)의 성형은, 금형에 금속재의 축부(20)를 구비한 상태에서 금형에 고무원료를 주입하여 경화시키면, 축부(20)의 일단면에고무머리부(10)가 일체로 부착된 고무머리볼트(2)가 형성된다.In the molding of the rubber head bolt 2, when the rubber raw material is injected into the mold and cured while the metal shaft portion 20 is provided in the mold, the rubber head portion 10 is integrally formed on one end surface of the shaft portion 20. A rubber head bolt 2 is attached thereto.
그러나, 이와 같은 종래의 고무머리볼트(2)는, 고무머리부(10)가 부착되는 축부(20)의 일단면이 매끄럽고 밋밋한 형상으로 형성되어 있기 때문에, 고무머리부(10)와 축부(20) 사이에는 고무의 접착력만이 결합력으로서 작용하여, 전기임팩트나 고무머리부(10)에 과도한 회전력이 작용될 시는, 고무머리부(10)와 금속재의 축부(20)가 서로 분리되어 떨어지게 되고, 그로 인해 고무머리볼트(2)를 더 이상 사용할 수 없게 되는 문제점이 있었다.However, since the one end surface of the shaft portion 20 to which the rubber head portion 10 is attached is formed in a smooth and flat shape, the rubber head portion 10 and the shaft portion 20 have such a conventional rubber head bolt 2. Only the adhesive force of the rubber acts as a bonding force between the), when excessive rotational force is applied to the electric impact or rubber head 10, the rubber head 10 and the metal shaft portion 20 is separated from each other, Thereby, there was a problem that the rubber head bolt 2 can no longer be used.
이에, 본 고안은 전술한 바와 같은 종래기술의 문제점을 해결하기 위해 안출된 것으로, 금속재로 이루어진 축부의 플랜지부를 고무머리부가 완전히 감싸도록 형성하여, 고무머리부와 금속재의 축부 사이의 마찰면적을 증대시킴으로써, 금속재의 축부와 고무머리부의 결합력을 강화시킨 고무머리볼트를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the problems of the prior art as described above, by forming the flange portion of the shaft portion made of a metal material so as to completely wrap the rubber head, the friction area between the rubber head and the shaft portion of the metal material It is an object of the present invention to provide a rubber head bolt which has enhanced the binding force between the shaft portion and the rubber head portion of a metal material.

이하, 본 고안의 바람직한 실시예를 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in detail as follows.
첨부도면 도 2 내지 도 6은 본 고안에 따른 고무머리볼트를 도시한 도면이다.2 to 6 are views showing a rubber head bolt according to the present invention.
도시된 바와 같이, 고무머리볼트(100)는 그 외주면에 나사산(302)이 형성되어 있는 금속재의 축부(300)와, 이 축부(300)의 일단부에 고정된 고무머리부(200)로 이루어진다.As shown, the rubber head bolt 100 is composed of a metal shaft portion 300 is formed with a screw thread 302 on its outer peripheral surface, and a rubber head portion 200 fixed to one end of the shaft portion 300. .
상기 금속재의 축부(300)는, 그 일단부에 축경보다 넓은 직경을 갖는 플랜지부(310)가 일체로 형성된다.The shaft portion 300 of the metallic material is integrally formed with a flange portion 310 having a diameter larger than the shaft diameter at one end thereof.
그리고, 상기 축부(300)의 플랜지부(310) 상면에는, 빗살무늬 형상의 돌출부(312)가 등간격의 방사상(放射狀)으로 형성된다.And, the upper surface of the flange portion 310 of the shaft portion 300, the comb-shaped projection 312 is formed in a radially equal intervals.
한편, 상기 플랜지부(310)의 저면에는 다수의 지지돌부(314)가 이격되게 돌출 형성되고, 상기 지지돌부(314) 사이에는 함몰된 다수의 요홈(316)이 이격되게 형성되어, 사출되는 고무머리부(200)와의 결합력을 증대시킨다.On the other hand, a plurality of support protrusions 314 are formed on the bottom surface of the flange portion 310 to project apart, a plurality of recessed grooves 316 recessed between the support protrusions 314 is formed, the rubber is injected Increase the bonding force with the head 200.
또한, 상기 고무머리부(200)는, 축부(300)의 플랜지부(310)를 감싸도록 형성된다.In addition, the rubber head 200 is formed to surround the flange portion 310 of the shaft portion 300.
상기 고무머리부(200)는, 플랜지부(310)를 감싸도록 사출 성형되어 플랜지부(310)에 부착 고정되고, 상기 플랜지부(310)의 돌출부(312)에 접하는 고무머리부(200)의 내측 상면에는 돌출부(312)에 대응한 요철(210)이 형성된다.The rubber head part 200 is injection molded to surround the flange part 310 and attached to and fixed to the flange part 310, and of the rubber head part 200 contacting the protrusion part 312 of the flange part 310. Concave-convex 210 corresponding to the protrusion 312 is formed on the inner upper surface.
그리고, 상기 고무머리부(200)의 내측 하면에는 지지돌부(314)에 의해서 이격되어 요홈(316)에 삽입되는 삽입돌부(230)가 형성되어, 고무머리부(200)의 결합력을 향상시킨다.In addition, an inner bottom surface of the rubber head 200 is formed with an insertion protrusion 230 spaced apart from the support protrusion 314 and inserted into the recess 316 to improve the bonding force of the rubber head 200.
따라서, 상기 고무머리볼트(100)는, 축부(300)의 플랜지부(310)와 이를 감싼 고무머리부(200) 사이의 결합력과 아울러, 상기 플랜지부(310)의 돌출부(312)와 고무머리부(200)의 요철(210) 및 상기 플랜지부(310)의 지지돌부(314)와 요홈(316)과 고무머리부(200)의 삽입돌부(230)에 의해 증대된 접촉면적 즉, 마찰면적으로 인해 고무머리부(200)와 축부(300)의 결합력이 증대된다.Thus, the rubber head bolt 100, as well as the coupling force between the flange portion 310 of the shaft portion 300 and the rubber head portion 200 wrapped therein, the protrusion 312 and the rubber head of the flange portion 310 The contact area that is increased by the unevenness 210 of the part 200, the support protrusion 314 of the flange part 310, the groove 316, and the insertion protrusion 230 of the rubber head 200, that is, the friction area. Due to this, the coupling force between the rubber head 200 and the shaft 300 is increased.
또한, 상기 고무머리부(200)의 저면 즉, 상기 축부(300)를 향하는 면에는 완만하게 돌출된 반원단면의 실링부(220)가 원주방향으로 형성되어, 고무머리볼트(100)가 결합되는 피대상물과의 접촉력이 증대되어 고무머리볼트(100)의 수밀성 및 기밀성을 향상시킨다.In addition, the bottom surface of the rubber head 200, that is, the surface facing the shaft portion 300 is formed in the circumferential direction of the sealing portion 220 of the semi-circular cross-section gently projected, the rubber head bolt 100 is coupled The contact force with the object is increased to improve the watertightness and airtightness of the rubber head bolt 100.
한편, 상기와 같이 구성된 고무머리볼트(100)의 사용시에는, 고무머리부(200)가 큰 회전력에도 견뎌 축부(300)와의 분리가 방지됨으로써 고무머리볼트(100)를 보다 견고하게 체결할 수 있다.On the other hand, when using the rubber head bolt 100 configured as described above, the rubber head 200 withstands a great rotational force to prevent the separation from the shaft portion 300 can be tightened more securely the rubber head bolt 100. .
즉, 상기 고무머리볼트(100)를 회전시키기 위해 고무머리부(200)에 제공되는 회전력은, 고무머리부(200)와 축부(300)의 플랜지부(310) 사이에 작용하는 결합력과, 고무머리부(200)의 요철(210)과 삽입돌부(230)가 플랜지부(310)의 돌출부(312)와 요홈(316) 및 지지돌부(314)에 접한 마찰력에 의한 합력보다 작기 때문에, 상기 고무머리부(200)와 축부(300)는 큰 회전력에도 견디는 결합력을 갖추게 된다.That is, the rotational force provided to the rubber head 200 to rotate the rubber head bolt 100, the coupling force acting between the rubber head 200 and the flange portion 310 of the shaft portion 300, rubber Since the unevenness 210 and the insertion protrusion 230 of the head 200 are smaller than the combined force due to the frictional force in contact with the protrusion 312 and the groove 316 and the support protrusion 314 of the flange 310, the rubber Head 200 and the shaft 300 is provided with a coupling force to withstand a large rotational force.
따라서, 상기 고무머리볼트(100)는 견고한 체결력으로 피대상물에 결합되고, 고무머리부(200)의 실링부(220)가 피대상물에 접하여 이의 수밀성 및 기밀성을 향상시킨다.Therefore, the rubber head bolt 100 is coupled to the object with a firm fastening force, the sealing portion 220 of the rubber head 200 in contact with the object to improve its watertightness and airtightness.
이상에서 설명한 바와 같이, 본 고안의 고무머리볼트에 의하면, 고무머리부와 금속재의 축부 사이의 마찰면적이 증대되어, 금속재의 축부와 고무머리부의 결합력이 강화되는 효과가 있다.As described above, according to the rubber head bolt of the present invention, the friction area between the rubber head and the shaft portion of the metal material is increased, and the bonding force between the shaft portion and the rubber head portion of the metal material is enhanced.
