* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 와셔본체 2 : 외측구멍협지용탄성편DESCRIPTION OF SYMBOLS 1 Washer main body 2: Elastic part for outer hole clamping
3 : 중앙구멍 4 : 절취부3: center hole 4: cutout
5 : 내측돌기 협지용 탄성편5: elastic piece for sandwiching the inner protrusions
본 고안은 목재 또는 연질성 사출물의 본체와 타측의 목재 또는 사출물의 본체를 보다 간편하고 견고하게 고정할 수 있도록 고안된 록킹와셔에 관한 것이다.The present invention relates to a locking washer designed to fix the main body of wood or soft injection molding and the main body of wood or injection molding on the other side more simply and firmly.
종래에 사출물 본체를 고정시키려면 도면 제3도의 (a)도와 (b)도와같이 스크류를 사용할 경우는 작업이 번거러울 뿐아니라 자재가 많이 소요되는 전후면 한쪽으로 스크류 머리가 돌출되게 되어 외형상으로 미려하지 못하였으며 스크류가 결착되는 사출돌기부가 미완되어 스크류가 쉽게 이탈되는 결점이 있었으며 도면 제3도의 (c)도의 경우에는 록킹와셔를 사용하여 임의의 판재를 고정시키기 위하여 사용되는 록킹와셔인 것으로 이는 사출물 본체에 돌설시킨 돌출부에 판재를 끼운다음 뒷면에서 와셔를 고정하는 것으로서 작업이 번거럽고 또한 뒷면이 개방되는 구조가 아니면 사용이 불가능한 결점이 있었다.Conventionally, in order to fix the main body of the injection molding, when the screw is used as shown in (a) and (b) of FIG. 3, the screw head protrudes to one side of the front and rear surfaces, which is not only cumbersome, but also requires a lot of materials. It was not beautiful, and there was a defect that the screw is easily detached because the injection protrusion part where the screw is fixed is missing. In the case of (c) of FIG. 3, the locking washer is used to fix an arbitrary plate using a locking washer. Inserting the plate into the protrusion protruding into the main body of the injection molding, and then fixing the washer on the back side, the work was cumbersome and the defect was impossible to use unless the structure is open on the back side.
본 고안은 종랭의 결점을 시정하기 위하여 고안된 것으로서 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is designed to correct the shortcomings of the end of the cooling bell as described in detail by the accompanying drawings as follows.
외측 둘레에 다수의 외측 구멍협지용 탄성편(2)을 후방으로 다소 경사돌출되게 절곡하여 형성시킨 와셔본체판(1)에 뚫은 중앙구멍(3)의 내측둘레에 외측구멍협지용 탄성편(2)과 대향 방향으로 절취부(4)에 의하여 전방으로 다소 경사돌출되는 내측 돌기 협지용탄성편(5)을 절곡형성시켜서된 것이다.Elastic piece for outer hole clamping (2) in the inner circumference of the central hole (3) drilled in the washer body plate (1) formed by bending a plurality of outer hole clamping elastic piece (2) to the rear periphery slightly inclined outwardly Is formed by bending the inner protruding sandwich elastic member 5 which is slightly obliquely projected forward by the cutout portion 4 in the opposite direction.
도면중 미설명부호 6은 일측사출물 본체 7은 타측사출물 본체 8은 일측사출물 돌기 9는 타측 사출물본체의 요입 구멍 10은 스크류를 표시한 것이다.In the drawings, reference numeral 6 denotes one injection molding main body 7, the other injection molding main body 8, one injection molding protrusion 9, and the recess hole 10 of the other injection molding main body is a screw.
이와같은 본 고안은 일측사출물본체(6)의 돌기부(8)에 록킹와셔(1)를 강압적으로 끼워 넣어 주게 되며 와셔(1)의 중앙구멍(3)의, 내주면이 절취부(4)에 의하여 형성된 내측돌기 협지용탄성편(5)이 일측사출물 본체(6)의 외주벽을 파고 들어감과 동시에 록킹와셔(1)의 외측구멍협지용탄상편(2)은 목재등의 타측사물물 본체(7)의 요입구멍(9)의 내부벽을 타고 들어가게 됨에 따라 일측사출물본체(6)의 돌기부(8)의 외주벽에 끼워 물림된 내측돌기협지용탄성편(5)과 타측사출물본체(7)의 요입구멍(9)의 내부벽에 끼워물림된 외측구멍협지용 탄성편(2)으로서 단일체로 형성된 와셔본체(1)에 의하여 일측사출물본체(6)와 타측사출물본체(7)가 견고하고 안정하게 고정조립되는 것이다.The present invention is such that the locking washer (1) is forcibly inserted into the projection (8) of one side injection molding body 6, the inner peripheral surface of the central hole (3) of the washer (1) by the cutout (4) The formed inner projection clamping elastic piece 5 penetrates the outer circumferential wall of the one-side injection body 6, and at the same time, the outer hole holding carbon upper piece 2 of the locking washer 1 is the other side object body such as wood. As the inner wall of the concave hole 9 of the concave hole 9 is inserted, the concave hole of the inner projection clamp elastic piece 5 and the concave hole of the other injection body 7 which are fitted into the outer circumferential wall of the projection 8 of the one injection body 6 The one side injection body 6 and the other side injection body 7 are firmly and stably assembled by the washer body 1 formed as a single body as the elastic piece 2 for outer hole clamping which is fitted to the inner wall of (9). will be.
이와같이된 본 고안은 와셔본체의 내외면 둘레에 내측 또는 외측으로 다소 경사지게 절곡하여 형성시킨 다수의 탄성편에 의하여 사출물본체의 요입구멍과 돌기부의 내외주벽에 강압적으로 파고 들어가면서 물려지게 되므로 사출물의 평탄도가 다소 만족하지 않더라도 사출물의 조립상태가 견고하고 안전하게 고정되는 것이며 조립 고정작업이 간편하고 용이한 것이다.In this way, the present invention has a flatness of the injection molding because it is pushed into the inner and outer circumferential walls of the indentation hole and the protrusion of the injection molding body by a plurality of elastic pieces formed by bending inclined inward or outward around the inner and outer surfaces of the washer body. Is somewhat unsatisfactory, the assembly state of the injection molding is firmly and securely fixed and the assembly fixing operation is simple and easy.
