본 고안은 휴대용 전기 디스크 그라인더의 숫돌을 외부의 충격으로부터 보호하는 역할을 하는 보호카버에 관한 것으로, 좀더 구체적으로는 보호카버를 간단한 조작에 의해 임의의 각도로 회전 고정시킬 수 있음은 물론 작업도중에 보호카버가 회전하는 것을 방지할 수 있는 보호카버 장치를 제공하기 위한 것이다.The present invention relates to a protective cover that serves to protect the grinding wheel of a portable electric disk grinder from external shocks. More specifically, the protective cover can be fixed and rotated at any angle by a simple operation as well as protection during operation. It is to provide a protective cover device that can prevent the cover is rotated.

종래에는 제3도 및 제4도에 도시한 바와 같이 숫돌(12)의 상단부분을 감쌀 수 있는 형태로된 숫돌카버(2)의 상부에 고정돌기(13a)를 가진 반원형상의 카버랜드(13)를 일체형으로 고정하고 이 카버랜드(13)의 일측에는 역시 고정돌기(14a)를 가진 동일한 형상의 체결밴드(14)를 스크류(15)로 결합하는 수단에 의해 숫돌카버(2)를 디스크 그라인더 본체의 하방 베어링 하우징(1)에 결합할 수 있게 하였다.Conventionally, a semi-circular carver land 13 having a fixing protrusion 13a on the top of the whetstone cover 2 in a shape capable of wrapping the upper part of the whetstone 12 as shown in FIGS. 3 and 4. To the wheel and the disc grinder body by means of coupling the fastening band 14 of the same shape having the fixing protrusion 14a to the screw 15 on one side of the carver land 13 by a screw 15. To the lower bearing housing (1).

따라서, 조립시 스크류(15)를 푼 상태에서 카버랜드(13)와 체결밴드(14)에 형성된 각 고정돌기(13a), (14a)를 베어링 하우징(1)에 형성된 홈으로 끼운후 스크류(15)를 조여주면 스크류의 체결력에 의해 각 밴드(13), (14)가 베어링 하우징(1)의 원주면에 밀착 고정되므로 숫돌카버(2)는 숫돌(12)을 감싼 상태로 유동하지 않게된다.Therefore, in the state of loosening the screw 15 at the time of assembly, each of the fixing protrusions 13a and 14a formed in the carver land 13 and the fastening band 14 is inserted into the groove formed in the bearing housing 1, and then the screw 15 ), The bands 13 and 14 are tightly fixed to the circumferential surface of the bearing housing 1 by the fastening force of the screw, so that the whetstone cover 2 does not flow while wrapping the whetstone 12.

그러나 상기한 종래의 장치는 숫돌카버(2)가 스크류(15)의 조임력에 의해 고정되는 구조이어서 그라인더 사용시의 진동에 의해 스크류(15) 약간 풀리는 경우 숫돌카버(2)가 작업자의 의사에 관계없이 임의의 방향으로 회전하여 작업에 지장을 초래하게 되고, 또 작업방향의 변경에 따라 숫돌카버(2)의 위치를 변경시킬 필요가 있을때에는 그때마다 드라이버로 스크류(15)를 풀어 숫돌카버(2)를 소정의 위치로 회전시킨 후 다시 스크류를 조여주어야 하는 사용상의 불편함이 있다.However, the conventional apparatus described above has a structure in which the grindstone cover 2 is fixed by the tightening force of the screw 15 so that when the screw 15 is slightly loosened by the vibration when using the grinder, the grindstone cover 2 is irrespective of the operator's intention. If it is necessary to change the position of the grindstone cover 2 in accordance with the change of the work direction by rotating in any direction and the work direction is changed, loosen the screw 15 with a screwdriver every time the grindstone cover 2 After rotating to a predetermined position there is an inconvenience in use to tighten the screw again.

본 고안은 종래의 장치가 지닌 이와 같은 결점을 해결하기 위한 것으로 이를 첨부된 도면에 의해 더욱 상세히 설명하면 다음과 같다.The present invention is to solve the above-mentioned drawbacks of the conventional apparatus and will be described in more detail by the accompanying drawings as follows.

숫돌카버(2)의 상부에 원형의 링밴드(3)를 일체형으로 고정하여 그 링밴드(3)의 양측에 ㄱ자상으로 절곡된 브라켓(5), (6)을 결합함과 함께 링밴드(3)의 일측에 형성된 구멍(4)에는 멈춤핀(7)을 스프링(8)으로 탄력설치하여 브라켓(6) 바깥측으로 돌출된 멈춤핀(7)의 끝부분에 놉(9)을 고정하고 베어링 하우징(1)의 원주면에는 다수의 고정홈(10)을 형성하여 멈춤핀(7)이 어느하나의 고정홀에 선택적으로 끼워져 결합될 수 있게한 것이다.A circular ring band 3 is fixed to the upper part of the whetstone cover 2 integrally, and the brackets 5 and 6 bent in an A shape on both sides of the ring band 3 are combined with the ring band ( In the hole (4) formed on one side of the 3) the stop pin (7) is elastically installed with a spring (8) to fix the knob (9) to the end of the stop pin (7) protruding out of the bracket (6) and bearing A plurality of fixing grooves 10 are formed on the circumferential surface of the housing 1 to allow the stop pin 7 to be selectively fitted into any one fixing hole.

도면중 미설명부호 11은 브라켓(5)을 링밴드(3)에 결합하기 위한 스크류이다.Reference numeral 11 in the figure is a screw for coupling the bracket 5 to the ring band (3).

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

먼저 숫돌카버(2)를 베어링 하우징에 조립할때에는 멈춤핀(7)의 끝부분에 고정된 놉(9)을 바깥방향으로 당긴 상태에서 링밴드(3)부분을 베어링 하우징(1)에 결합하게 되는데, 놉(9)을 당기면 스프링(8)이 압축되면서 멈춤핀(7)이 함께 당겨지고 이 상태에서 링밴드(3)에 결합된 브라켓(5), (6)중 놉(9)이 결합된 부분의 브라켓(6)을 바깥으로 당겨주면 브라켓 사이의 간격이 벌어지게되므로 ㄱ자상으로 절곡된 각 브라켓(5), (6)의 상단 절곡부분을 베어링 하우징(1)에 형성된 홈으로 끼울수 있게 된다.First, when assembling the whetstone cover 2 to the bearing housing, the ring band 3 is coupled to the bearing housing 1 while the knob 9 fixed to the end of the stop pin 7 is pulled outward. When the knob 9 is pulled, the spring 8 is compressed and the stop pin 7 is pulled together, and in this state, the knob 9 of the brackets 5 and 6 coupled to the ring band 3 is engaged. Pulling out the bracket (6) of the part will open the gap between the brackets, so that the upper bent portion of each bracket (5), (6) bent in a shape to fit into the groove formed in the bearing housing (1) do.

이렇게 각 브라켓(5), (6)이 베어링 하우징(1)의 홈에 끼워질 수 있도록 된 상태에서 숫돌카버(2)를 회전시켜 멈춤핀(7)이 베어링 하우징(1) 원주면에 형성된 다수(통상 8-12개)의 고정홈(10)중 어느하나의 고정홈과 일치되게한 후 당겨져 있던 놉(9)을 놓으면 스프링(8)의 복원력에 의해 멈춤핀(7)이 고정홈(10)에 끼워짐과 동시에 브라켓(6)도 안쪽으로 이동하여 베어링 하우징(1)의 홈으로 끼워지게되므로 숫돌카버(2)는 고정되는 것이다.In this state, each of the brackets 5 and 6 can be fitted into the grooves of the bearing housing 1, thereby rotating the whetstone cover 2 so that the stop pins 7 are formed on the circumferential surface of the bearing housing 1. When the knob (9) is pulled out after matching the fixing groove of any one of the fixing grooves (typically 8-12 pieces), the stop pin 7 is fixed by the restoring force of the spring (8). At the same time, the bracket 6 is also moved inwards to be fitted into the groove of the bearing housing 1, so that the whetstone cover 2 is fixed.

즉, 멈춤핀(7)이 고정홈(10)에 끼워진 상태에서는 멈춤핀(7)에 의해 숫돌커버(2)의 회전이 불가능해지고 베어링 하우징(1)의 홈으로 끼워진 각 브라켓(5), (6)에 의해 숫돌카버(2)가 하방으로 흘러내리지 않게되는 것이다.That is, in the state in which the stop pin 7 is fitted into the fixing groove 10, the brackets 2 cannot be rotated by the stop pin 7, and the respective brackets 5, (which are fitted into the grooves of the bearing housing 1) ( By 6) the whetstone cover 2 will not flow down.

또 가공물의 작업방향에 따라 숫돌카버(2)의 회전위치를 변경시킬 필요가 있을 때 놉(9)을 당겨 멈춤핀(7)이 고정홈(10)에서 빠져나오게한 후 숫돌카버(2)를 원하는 위치로 회전시킨 다음 당겼던 놉(9)을 놓아주기만 하면 멈춤핀(7)이 다른 고정홈에 끼워져 고정되므로 드라이버와 같은 공구를 사용하지 않고도 숫돌카버(2)의 위치를 용이하게 변경시킬 수 있게 되는 것이다.In addition, when it is necessary to change the rotational position of the grindstone cover 2 according to the working direction of the workpiece, pull the knob 9 so that the stop pin 7 comes out of the fixing groove 10, and then remove the grindstone cover 2 Simply turn the knob (9) to the desired position and then release the stop pin (7) into the other fixing groove so that it can be easily repositioned without the use of tools such as a screwdriver. Will be.

이상에서와 같이 본 고안은 스크류에 의한 밴드의 조임력에 따라 숫돌카버가 베어링 하우징에 조립되는 종래의 장치와는 달리 브라켓과 멈춤핀에 의해 숫돌카버가 베어링 하우징에 조립되는 구조이어서 그라인더의 사용시 진동이 가해지는 경우에도 숫돌카버가 견고한 조립상태를 유지할 수 있게되고 숫돌카버의 위치변경 조작이 용이해지는 사용상의 편리함을 제공한다.As described above, the present invention has a structure in which the grinding wheel cover is assembled to the bearing housing by the bracket and the stop pin, unlike the conventional device in which the grinding wheel cover is assembled to the bearing housing according to the tightening force of the band by the screw. Even when applied, the grindstone cover can maintain a solid assembly state and provide convenience in use that facilitates the position change operation of the grindstone cover.
