본 고안은 음극선관 체결나사에 관한 것으로, 특히 가전제품의 조립이 완료된 후 외부진동에 의해서 체결나사가 풀려지는 것을 방지토록 하는 음극선관 고정장치에 관한 것이다.The present invention relates to a cathode ray tube fastening screw, and more particularly, to a cathode ray tube fixing device for preventing the fastening screw from being released by external vibration after assembly of the home appliance is completed.

종래에는 제1도에서와 같이, 보스(1)에 나사산을 만들면서 체결되는 나사(2)와, 상기 나사(2)가 보스(1)에 체결된 후 풀림을 방지하도록 하는 돌기(3a)를 갖는 와셔(3)로 구성된다.Conventionally, as shown in FIG. 1, a screw 2 fastened while making a thread on the boss 1 and a protrusion 3a for preventing loosening after the screw 2 is fastened to the boss 1 are provided. Having a washer (3).

이와같이, 종래의 고안을 조립코져 한다면 음극선관 러그(LUG)(4)를 보스(1)위에 얹고서 드라이버나 스패너 등 체결공구를 사용하여 나사(2)를 시계방향으로 회전시켜 체결한다.As described above, in order to assemble a conventional design, the cathode ray tube lug 4 is placed on the boss 1, and the screw 2 is rotated clockwise by using a fastening tool such as a screwdriver or a spanner.

이때 나사(2)는 보스(1)에 나사산(1a)을 만들면서 체결이 이루어진다.At this time, the screw 2 is fastened while making the thread 1a in the boss 1.

이와같이 나사(2)를 계속적으로 조이게 되면 나사머리(2a)에 의해 와셔(3)가 눌리게 되고 와셔(3)의 돌기(3a)는 음극선관러그(4)를 누르게 되면서 나사(2)의 체결은 완료된다.In this way, if the screw 2 is continuously tightened, the washer 3 is pressed by the screw head 2a, and the protrusion 3a of the washer 3 presses the cathode ray tube lug 4 while the screw 2 is fastened. Is complete.

이때 와셔(3)의 돌기(3a)는 음극선관 러그(4) 상부를 탄성적으로 누르게 되고 그 반발력은 다시 나사(2)를 밀어 올리게 되므로 나사(2)는 와셔(3)의 탄성력에 의해 쉽게 이탈되지 않는다.At this time, the protrusion 3a of the washer 3 elastically presses the upper portion of the cathode ray tube lug 4 and the repulsive force pushes up the screw 2 again, so that the screw 2 is easily driven by the elastic force of the washer 3. It does not break away.

그러나 나사의 체결은 단지 와셔의 탄성력에 의해 이루어져 있으므로 나사의 충분하 토오크 상태의 유지가 필수적인데 만약 무거운 하중의 음극선관을 고정하고 있는 경우에 가전제품의 외부진동에 의해 나사의 체결이 풀려지는 문제점이 있었다.However, since the screw is made only by the elastic force of the washer, it is essential to maintain sufficient torque. The screw is loosened by external vibration of household appliances when the cathode ray tube of heavy load is being fixed. There was this.

본 고안은 이러한 문제점을 감안하여 안출한 것으로서, 음극선관 러그를 보스에 체결하는 체결나사와, 상기 체결나사가 보스에 체결됨에 따라 탄성적으로 고정되는 제1고정수단과, 상기 제1고정수단과 결합되어 체결나사의 이탈을 방지하는 제2고정수단으로 구성된 가전제품의 음극선관 고정장치를 제공하여 진동에 의해 체결나사가 풀려지는 것을 방지토록 하는 것이 목적이다.The present invention has been made in view of the above problems, the fastening screw for fastening the cathode ray tube lug to the boss, the first fixing means is elastically fixed as the fastening screw is fastened to the boss, and the first fixing means and It is an object to provide a cathode ray tube fixing device of a home appliance composed of a second fixing means coupled to prevent the separation of the fastening screw to prevent the fastening screw is loosened by vibration.

본 고안의 구성을 제2도 내지 제6도에 의거 설명한다.The configuration of the present invention will be described based on FIGS. 2 to 6.

음극선관 러그(4)를 보스에 체결하는 체결나사(10)와, 상기 체결나사(10)가 체결됨에 따라 탄성적으로 고정되는 제1고정수단(30)과, 상기 제1고정수단(30)과 결합되어 체결나사(10)의 이탈을 막아주는 제2고정수단(20)으로 구성된다.A fastening screw 10 for fastening the cathode ray tube lug 4 to the boss, a first fastening means 30 which is elastically fixed as the fastening screw 10 is fastened, and the first fastening means 30. It is combined with the second fixing means 20 to prevent the separation of the fastening screw 10 is configured.

체결나사(10)는 상부나사산(13)과 하부나사산(14)으로 분리되어 있으며, 상부나사산(13)에서 나사머리(11)로 감에 따라 굵어지는 몸통(12)으로 구성된다.The fastening screw 10 is separated into an upper screw thread 13 and a lower screw thread 14, and is composed of a body 12 that is thickened as it goes from the upper screw thread 13 to the screw head 11.

제1고정 수단(30)은 상부로 돌출 형성된 돌출부(31)와, 상기 돌출부(31)주위에 복수개 형성된 탄성홈(32)과, 상기 탄성홈(32) 사이의 돌출부 주위에 복수개 형성된 안착돌기(33)와, 상기 돌출부(31) 내측에 형성된 고정나사산(34)과, 상기 돌출부(31)에서 하부로 형성되어 제1고정수단(30)을 음극선관 러그(4)에 안착시켜서 움직임을 차단하는 스토퍼(35)로 구성된다.The first fixing means 30 includes a protrusion 31 protruding upward, a plurality of elastic grooves 32 formed around the protrusion 31, and a plurality of seating protrusions formed around the protrusion between the elastic grooves 32. 33), a fixed screw thread 34 formed inside the protrusion 31, and a lower portion of the protrusion 31 to seat the first fixing means 30 on the cathode ray tube lug 4 to block movement. It consists of a stopper 35.

제2고정수단(20)은 제1고정수단(30)의 돌출부(31)가 벌려지므로서, 안착 돌기(33)가 안착되는 안착홈(21)과, 상기 안착홈(21)을 형성시키도록 해주는 외측홈(22)과, 상기 제1고정수단(30)의 스토퍼(35)에 삽설되는 고정홈(23)으로 구성된다.The second fixing means 20 is formed so that the protrusions 31 of the first fixing means 30 are opened, thereby forming a seating groove 21 on which the seating projection 33 is seated, and the seating groove 21. The outer groove 22 and the fixing groove 23 is inserted into the stopper 35 of the first fixing means (30).

본 고안의 작용, 효과를 첨부도면에 의해 상세히 설명한다.The operation and effects of the present invention will be described in detail by the accompanying drawings.

본 고안을 조립코져 한다면 체결나사(10)를 제2고정수단(20), 제2고정수단(30)에 순차적으로 관통시켜 결합하게 되면 제5도와 같은 상태가 된다.When the present invention is assembled, the fastening screw 10 passes through the second fixing means 20 and the second fixing means 30 in sequence so as to be in a state as shown in FIG. 5.

이와같이 상기의 상태에서 제6도에서와 같이 체결 나사(10)의 하부 나사산(14)을 음극선관 러그(4)의 구멍(41)과 보스(50)에 끼워서 드라이버로 체결나사(10)를 시계 방향으로 회전시켜 조이면 하부 나사산(14)이 보스 내측에 나사산을 만들면서 진입하게 된다.In this manner, as shown in FIG. 6, the lower thread 14 of the fastening screw 10 is inserted into the hole 41 and the boss 50 of the cathode ray tube lug 4, and the fastening screw 10 is clocked with a screwdriver. When the screw is rotated in the direction, the lower thread 14 enters while making a thread inside the boss.

그리고, 제1고정수단(30)의 돌출부(31) 내측에 형성된 고정나사산(34)과 맞물려 회전하는 상부나사산(13)의 진입이 이루어지면서 몸통(12)이 닿게 된다.Then, the body 12 is brought into contact with the entry of the upper screw thread 13 which rotates in engagement with the fixed screw thread 34 formed inside the protrusion 31 of the first fixing means 30.

이와같이 체결나사(10)를 계속적으로 조이게 되면 체결나사(10)의 몸통(12)이 제1고정수단(30)의 돌출부(31)내로 진입함에 따라 안착돌기(33)가 점차적으로 외측으로 벌려지게 된다.When the fastening screw 10 is continuously tightened in this way, the body 12 of the fastening screw 10 enters the protrusion 31 of the first fixing means 30 so that the seating protrusion 33 is gradually spread outward. do.

이와같이 안착돌기(33)가 제2고정수단(20)의 안착홈(21)에 삽설되어지는데 이것은 제2고정수단(20)이 가전제품의 사용에 의해 심한 진동을 받더라도 회전되지 않으므로 결국 체결나사(10)는 절대로 풀려지지 않게 되는데 고정홈(23)은 스토퍼(35)위해 삽설되고 고정돌기(24)는 음극선관 러그(4)를 누르게 된다.In this way, the seating protrusion 33 is inserted into the seating groove 21 of the second fixing means 20. This is because the second fixing means 20 is not rotated even when subjected to severe vibration by the use of home appliances. 10) is never released, the fixing groove 23 is inserted for the stopper 35 and the fixing protrusion 24 is pressed against the cathode ray tube lug (4).

그리고 제1고정수단(30)의 스토퍼(35) 역시 음극선관 러그(40) 사이에 삽설되므로 제1고정수단(30)은 절대로 움직이지 않는다.In addition, since the stopper 35 of the first fixing means 30 is also inserted between the cathode ray tube lugs 40, the first fixing means 30 never moves.

따라서, 종래와 다르게 새로운 고정수단이 부가되므로서 가전제품에 어떤 진동이 가해지더라도 체결나사의 풀림이 방지되므로 가전제품의 품질을 향상시키는 유용한 고안이다.Therefore, unlike the prior art, a new fixing means is added, and thus any loosening of the fastening screw is prevented even if any vibration is applied to the home appliance, which is a useful design to improve the quality of the home appliance.
