상기 구조로 되어 있는 본 발명 실시예에 의한 연장관 관절구조의 작용을 살펴보기로 한다.The operation of the extension tube joint structure according to the embodiment of the present invention having the above structure will be described.

사용자가 본 발명 실시예에 의한 청소기로 청소를 할 때, 일직선의 연장관(20,50)으로 청소하기 곤란한 탁자 밑의 청소 시에는 상기 손잡이(55)에 설치된 레버(68)를 도 2에 표시된 화살표 방향인 안으로 당겨주게 된다.When the user cleans using the vacuum cleaner according to the embodiment of the present invention, when cleaning under the table that is difficult to clean with straight extension tubes 20 and 50, the lever 68 installed on the handle 55 is indicated by the arrow shown in FIG. 2. Pull in.

상기 작용에 의하여 와이어(64)와 연결된 레버(68) 일단은 도 3에 도시된 바와 같이 지지판(66) 방향으로 이동하게 되며, 일단에 연결된 와이어(64)가 아래로 밀리며 힘을 전달하게 된다. 상기 와이어(64)를 타고 전달된 힘은 와이어(64)와 연결되어서 상부연장관(50) 하단에 장착된 잠금돌기(60)의 일단을 아래로 밀게 된다.As described above, one end of the lever 68 connected to the wire 64 moves in the direction of the supporting plate 66 as shown in FIG. The force transmitted through the wire 64 is connected to the wire 64 to push down one end of the locking projection 60 mounted on the lower end of the upper extension pipe 50.

이로 인하여, 잠금돌기(60) 일단과 일체로 형성된 잠금돌기(60) 타단은 원형판 잠금홈(46)에 삽입된 상태에서, 도 3에 도시된 바와 같이 상부로 이동하여 잠금홈(46)에서 분리되어 상기 관절회전부(30)의 회전이 자유롭게 된다. 상기 상태로된 청소기의 손잡이(55)를 하부로 약간 내리는 것에 의하여 상기 하부연장관(20)은 아래로 꺾이게 되어서, 가구 밑의 청소가 용이해진다.Due to this, the other end of the locking projection 60 formed integrally with one end of the locking projection 60 is inserted into the circular plate locking groove 46, and moved upward to separate from the locking groove 46 as shown in FIG. The rotation of the joint rotation unit 30 is free. The lower extension tube 20 is bent downward by slightly lowering the handle 55 of the cleaner in the above state, thereby facilitating cleaning under the furniture.

그리고, 사용자가 상기 레버(68)를 놓으면 레버(68)의 일단을 지지하고 있는 스프링에 의하여 레버(68)를 원위치로 하기 위한 복귀력이 작용하게 되며, 이에 따라 상기 와이어(64)와 연결된 잠금돌기(60)는 원위치로 이동하게 된다.Then, when the user releases the lever 68, the return force for returning the lever 68 to the original position by the spring supporting one end of the lever 68 acts, thereby locking the connection with the wire 64 The projection 60 is moved to the original position.

사용자는 가구 밑의 청소를 끝낸 후에, 다시 상부연장관(50)과 하부연장관(20)을 일직선으로 위치하는 것에 의하여 도 2에 도시된 바와 같이, 상기 잠금돌기(60)는 잠금홈 측면의 경사부를 따라 이동하여 잠금홈(46)에 삽입되어 고정되는 것에 의하여, 상기 관절회전부(30)의 회전을 방지하게 된다.After the user finishes cleaning under the furniture, the upper extension tube 50 and the lower extension tube 20 are positioned in a straight line, as shown in FIG. 2, so that the locking protrusion 60 is inclined at the side of the locking groove. By moving along and being inserted into the locking groove 46 to be fixed, the rotation of the joint rotation part 30 is prevented.

상기에서 관절회전부(30)의 작용을 상세히 살펴보면, 내측회전부 제1연결관(36)과 접하여 있는 외측원형부(40)의 일단이 내측원형부(34)의 일단과 소정길이 접하는 위치까지 회전하게 되면, 외측원형부(40)의 타단은 내측원형부(34)의 타단과 소정길이 접하는 위치에서 제1연결관(36)과 접하는 위치까지 회전하게 된다.Looking at the action of the joint rotation unit 30 in detail, one end of the outer circular portion 40 in contact with the inner rotating first connection pipe 36 to rotate to a position in contact with one end of the inner circular portion 34 a predetermined length.
